The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
∠ 4 is an exterior angle of the triangle, then
∠ 4 = ∠ 2 + ∠ 3
please help me find the area
Answer: 150m
Step-by-step explanation: you first remove 5 from 20 to get what you should multiply for your triangle then you get 15 and multiply it by 12 to get 180 then you divide by 2 since it’s a triangle, to get 90 then you find the area of the rectangle by multipling 5 by 12 to get 60 then 60+90=150
Answer:
150 meters
Step-by-step explain
He formula for a triangle is a=bh/2. it ends up being a=12x15/2=90.
The formula for a rectangle is 12x5=60.
You take both and add them together and you get 150.
So the answer is 150 meters.

A. 223 were not playing volleyball
B. 12 books on each shelf with 3 books left over..
C. 12.15$ a day
D. 12.15 miles per day.
Step-by-step explanation:
A. Subtract 20 from 243.
B. Since books cant be divided into fractions, you take 243 divided by 20, which is 12.15. However, we have to say 12 with 3 leftover because books isn't money, a distance measure, etc. and cannot be cut into pieces.
C. 243 / 20 is 12.15
D. 243 / 20 is 12.15

To test the hypothesis that the population standard deviation sigma 12.1, a sample size n=7 yields a sample standard deviation 10.394. Calculate the P- value and choose the correct conclusion. Your answer: The P-value 0.016 is not significant and so does not strongly suggest that sigma<12.1. The P-value 0.016 is The P-value 0.016 is significant and so strongly suggests that sigma<12.1. The P-value 0.381 is not significant and so does not strongly suggest that sigma<12.1. The P-value 0.381 is O significant and so strongly suggests that sigma<12.1. The P-value 0.021 is not significant and so does not strongly suggest that sigma<12.1. The P-value 0.021 is significant and so strongly suggests that sigma<12.1. suggests that sigma<12.1. The P-value 0.015 is not significant and so does not strongly suggest that sigma<12.1. The P-value 0.015 is significant and so strongly suggests that sigma<12.1. The P-value 0.199 is not significant and so does not strongly suggest that sigma<12.1. The P-value 0.199 is O significant and so strongly suggests that sigma<12.1.
The calculated p-value is 0.016, which is significant. However, it does not strongly suggest that the population standard deviation (sigma) is less than 12.1.
In hypothesis testing, the p-value is used to determine the strength of evidence against the null hypothesis. In this case, the null hypothesis is that the population standard deviation (sigma) is equal to 12.1. The alternative hypothesis would be that sigma is less than 12.1.
A p-value of 0.016 means that if the null hypothesis were true (sigma = 12.1), there is a 1.6% chance of obtaining a sample with a standard deviation of 10.394 or lower. Typically, a p-value below a chosen significance level (e.g., 0.05) is considered statistically significant. However, in this case, the p-value of 0.016 is still relatively close to the significance level, indicating a moderate level of evidence against the null hypothesis.
Therefore, based on the given information, we can conclude that the p-value of 0.016 is significant, but it does not strongly suggest that the population standard deviation is less than 12.1. Strong evidence would require a smaller p-value, further away from the significance level, to support the alternative hypothesis.

9) set 21 and 22 be rings with identities ter and 1R₂, respectively. Prove that the set of all Toleals of R1X22 = $ Il x I₂: It is on Ideal of 21 and is an ideal of R2}.
The Set of all ideals of R₁×R₂, denoted as I₁×I₂, is an ideal of R₁×R₂, and it is also an ideal of R₁ and R₂ separately.
To prove that the set of all ideals of R₁×R₂, denoted as I₁×I₂, is an ideal of R₁×R₂, we need to demonstrate that it satisfies the necessary properties of an ideal.
1. Closure under addition: Let (a, b) and (c, d) be two elements in I₁×I₂. We need to show that their sum, (a, b) + (c, d), is also in I₁×I₂. Since both (a, b) and (c, d) are in their respective ideals, this implies that a+c is in I₁ and b+d is in I₂. Therefore, (a+c, b+d) is in I₁×I₂, showing closure under addition.
2. Closure under scalar multiplication: Let (a, b) be an element in I₁×I₂ and (r, s) be an arbitrary element in R₁×R₂. We need to show that their scalar product, (a, b)(r, s), is in I₁×I₂. Since a is in I₁, and R₁ is a ring with identity, we have ar is in I₁. Similarly, since b is in I₂ and R₂ is a ring with identity, we have bs is in I₂. Therefore, (ar, bs) is in I₁×I₂, demonstrating closure under scalar multiplication.
3. Contains additive identity: The additive identity in R₁×R₂ is (0, 0). Since both I₁ and I₂ are ideals, they contain their respective additive identities. Therefore, (0, 0) is in I₁×I₂.
Since the set of all ideals of R₁×R₂, denoted as I₁×I₂, satisfies closure under addition, closure under scalar multiplication, and contains the additive identity, it meets the definition of an ideal of R₁×R₂.
Additionally, since I₁×I₂ is a subset of both I₁ and I₂, it is an ideal of R₁ and R₂ individually.
In conclusion, the set of all ideals of R₁×R₂, denoted as I₁×I₂, is an ideal of R₁×R₂, and it is also an ideal of R₁ and R₂ separately.

Tom's dad is putting crown molding around the top of all of the walls in Tom's bedroom. The dimensions of his bedroom are shown. A rectangle that is eleven and three-fourths feet wide and fifteen and three-fourths feet long. Each foot of crown molding costs $0.85. What is the total cost of the crown molding?
Answer:
$157.30
Step-by-step explanation:
Width of the rectangular bedroom = 11 3/4 feet
Length of the rectangular bedroom = 15 3/4 feet
Area of the rectangular bedroom = length × width
= 15 3/4 × 11 3/4
= 63/4 × 47/4
= 2,961 / 16
= 185.0625 feet ²
Area of the rectangular bedroom = 185.0625 feet ²
Cost of each foot of crown molding = $0.85
Total cost of the crown molding = 185.0625 × $0.85
= $157.303125
Approximately,
Total cost of the crown molding = $157.30

On any weekday during the semester, the probability that Beth does yoga is 0.75, the probability that Beth walks is 0.40, and the probability that Beth does both is equal to 0.20. Round your answers to two decimals. Write your answers in the form O.XX! What is the probability that Beth does yoga knowing that she walked? What is the probability that Beth walks knowing that she did yoga? Are the events "Beth does yoga" and "Beth walks" independent events? Are the events "Beth does yoga" and "Beth walks" dependent events?
The probability that Beth does yoga knowing that she walked is 0.50. The probability that Beth walks knowing that she did yoga is 0.27. The events "Beth does yoga" and "Beth walks" are dependent events.
To calculate the probability that Beth does yoga knowing that she walked, we use the formula for conditional probability. The probability of Beth doing yoga given that she walked is equal to the probability of both events occurring (Beth does both) divided by the probability of the given event (Beth walks). In this case, the probability of Beth doing yoga and walking is 0.20, and the probability of Beth walking is 0.40. Therefore, the probability that Beth does yoga knowing that she walked is 0.20/0.40 = 0.50.
Similarly, to calculate the probability that Beth walks knowing that she did yoga, we use the formula for conditional probability. The probability of Beth walking given that she did yoga is equal to the probability of both events occurring (Beth does both) divided by the probability of the given event (Beth does yoga). In this case, the probability of Beth doing yoga and walking is 0.20, and the probability of Beth doing yoga is 0.75. Therefore, the probability that Beth walks knowing that she did yoga is 0.20/0.75 ≈ 0.27.
Since the conditional probabilities are not equal to the individual probabilities of each event, we can conclude that the events "Beth does yoga" and "Beth walks" are dependent events. The occurrence of one event affects the probability of the other event, indicating a dependence between the two activities.

There are 30 red marbles and the ratio of black to yellow is 4/5, so 4/5=orange/green=orange/30.
30 is 6 times 5, so black=6 times 4=24. There are 24 black marbles.
Total of black and yellow=24+30=54.
40% of the marbles are green so 60% are black/yellow. Also 60% is 54 marbles.
60% is 60/100=3/5 so 3/5 of the total is 54 marbles, therefore 1/5 is 54/3=18 and 2/5 is the number of red marbles=2 times 18=36 red marbles.

95% confidence interval.
99% confidence interval.
A. The 95% self-belief interval for the percentage of humans making plans to take a one-week excursion this summer time is approximately 0.351 to 0.369.
B. The 99% confidence c programming language for the share of people planning to take a one-week vacation this summer time is approximately 0.348 to 0.372.
C. The 99% self-assurance c program language period is wider than the 95% confidence c language.
A. To assemble the 95% confidence c programming language for the percentage of individuals who plan to take a one-week excursion this summer time, we will use the formula for the self-belief c programming language of a proportion:
CI = p ± z * [tex]\sqrt{((p(1 - p)) / n)}[/tex]
in which p is the pattern percentage, z is the z-score corresponding to the preferred self-belief degree, and n is the sample size.
From the given relative frequency distribution, we will see that the proportion of humans planning to take a one-week excursion is 0.36. The pattern size is 3,057.
Using a z-table for a 95% confidence stage, the z-score similar to a two-tailed test is approximately 1.96.
Plugging the values into the formula, we have:
CI = 0.36 ± 1.96 * [tex]\sqrt{((0.36(1 - 0.36)) / 3,057)}[/tex]
Calculating this expression, we get:
CI = 0.36 ± 1.96 *[tex]\sqrt{ (0.2304 / 3,057)}[/tex]
CI = 0.36 ± 1. 96 * 0.00473
CI ≈ 0.36 ± 0.00928
Therefore, the 95% self-belief interval for the percentage of humans making plans to take a one-week excursion this summer time is approximately 0.351 to 0.369.
B. To assemble the 99% self-assurance c programming language, we use the same formula as above however with a unique z-score.
Using a z-table for a 99% self-belief level, the z-rating similar to a two-tailed take a look at is approximately 2.576.
Plugging the values into the formula, we've got:
CI = 0.36 ± 2.576 * [tex]\sqrt{((0.36(1 - 0.36)) / 3,057)}[/tex]
Calculating this expression, we get:
CI = 0.36 ± 2.576 * [tex]\sqrt{(0.2304 / 3,057)}[/tex]
CI = 0.36 ± 2.576 * 0.00473
CI ≈ 0.36 ± 0.01217
Therefore, the 99% confidence c programming language for the share of people planning to take a one-week vacation this summer time is approximately 0.348 to 0.37.
C. The 99% self-assurance c p2rogram language period is wider than the 95% confidence c language. This is because a higher self-belief stage requires a larger margin of mistakes, resulting in a wider range across the factor estimate.

The pair (6, 3) in R, (6, 4) in R, and (C, 3) in R couldn't be matched with any pair in S, so they are not included in the composition relation RS.
To find the composition relation RS of R with S, we need to combine the ordered pairs in R and S in a way that the second element of each pair in R matches the first element of the pair in S.
Let's perform the composition:
R = {(2, 1), (6, 3), (6, 4), (C, 3)}
S = {(1, y), (1, 2), (2, w), (3, z)}
To form RS, we match the second element of each pair in R with the first element of each pair in S:
(2, 1) in R matches with (1, y) in S, so we combine them to form (2, y).
(2, 1) in R matches with (1, 2) in S, so we combine them to form (2, 2).
(6, 3) in R doesn't match with any pair in S.
(6, 4) in R doesn't match with any pair in S.
(C, 3) in R doesn't match with any pair in S.
Therefore, the composition relation RS is: RS = {(2, y), (2, 2)}
