If one of the 50 states is chosen at random, then a dice is rolled. Find the probability of getting a state that starts with the letter A and a number less than 3. Pls, help me this is due by tomorrow at 8 am!
Answers
Note: 2/75 = 0.0267 = 2.67% approximately
========================================================
Explanation:
The states that start with "A" are:
AlabamaAlaskaArizonaArkansasWe have four states out of 50 total. The probability of picking a state that starts with "A" is 4/50 = 2/25.
When rolling a single die, the possible outcomes are {1,2,3,4,5,6}. The subset {1,2} represents any time we roll less than three. There are 2 ways to roll less than three, out of 6 ways total. So we have a probability of 2/6 = 1/3 here.
We'll multiply the fractions to get our answer:
(2/25)*(1/3) = (2*1)/(25*3) = 2/75

Answer:
this is so easy like just put variables a in b
Step-by-step explanation:
hope you get it
The Question is what is the mean of the snakes lengths. The mean means you line all of your numbers up in order then you add all of the numbers up and when you get the total you divide the total plus the amount of numbers you have. So in this case the numbers would be: 8,17,22,39,44..next you would add all them up so it would be the next step would be to count the numbers up and divide that by the total...so it will be 5/130=26 so the mean for this question will be 26....hope it helps :)

1 and 2 are complementary angles. The measure of 1 is 54 . The measure of 2 is 6(x +1). Find the value of x.
Answers
Answer:
x = 5
Step-by-step explanation:
Complementary angles are two angles that add up to 90 degrees. 90 - 54= 36, so 6(x+1), or 6x+6 = 36. You subtract 6 from both sides to get 6x=30, then divide by 6 on both sides to get x=5. So the answer would be x=5.
You are buying decorations for a birthday party. Six rolls of crepe paper and 20 balloons cost $11.90. After you start decorating, you need more supplies. You buy 2 more rolls of crepe paper and 15 more balloons for $6.05.
Answers
Answer: $1.15
Step-by-step explanation:
The question is How much did each roll of crepe paper cost?
Let the cost of crepe paper be x
Let the cost of balloons be y.
Six rolls of crepe paper and 20 balloons cost $11.90. This will be:
6x + 20y = 11.90 ......... i
2 more rolls of crepe paper and 15 more balloons for $6.05. This will be:
2x + 15y = 6.05 ......... ii
6x + 20y = 11.90 ......... i
2x + 15y = 6.05 ......... ii
Multiply equation i by 15
Multiply equation ii by 20
90x + 300y = 178.50 ........ iii
40x + 300y = 121 ........ iv
Subtract iv from iii
50x = 57.50
x = 57.50/50
x = 1.15
Therefore, a crepe paper cost $1.15

On the SAT exam, a total of 25 minutes is allotted for students to answer 20 math questions without the use of a calculator. A guidance counselor would like to know if the students in his school are prepared to complete this portion of the exam in the time allotted. To investigate, the counselor selects a random sample of 35 students and administers this portion of the test. The students are instructed to turn in their test as soon as they have completed the questions. The mean amount of time taken by the students is 23.5 minutes with a standard deviation of 4.8 minutes. The counselor would like to know if the data provide convincing evidence that the true mean amount of time needed for all students of this school to complete this portion of the test is less than 25 minutes. What are the appropriate hypotheses?
H0: μ = 23.5 versus Ha: μ < 23.5, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
H0: μ = 23.5 versus Ha: μ > 23.5, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
H0: μ = 25 versus Ha: μ < 25, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
H0: μ = 25 versus Ha: μ > 25, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
Answers
Answer:
H0: μ = 23.5 versus Ha: μ < 23.5, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam
The hypothesis is H0: μ = 25 versus Ha: μ < 25, So option (C) is the correct answer.
What is mean and standard deviation?Mean is the ratio of the sum of all the observations and the total number of observations in a data set. The standard deviation is a statistic that measures the dispersion of a data set relative to its mean and is calculated as the square root of the variance.
For the above suituation,
There are 20 math questions to be answered in 25 minutes.
After investigation with 35 students, the meantime needed for them is 23.5 and the standard deviation is 4.8.
From the above information, we can say that the hypothesis, H0: μ = 25 versus Ha: μ < 25, where μ = the true mean amount of time needed for students of this school to complete this portion of the exam.
Hence we can conclude that the hypothesis (C) is the correct answer.

Colin was thinking of a number. Colin adds 10, then divides by 6 to get an answer of -8. What was the original number?
Answers
Answer: - 58
Step-by-step explanation:
First, let us think of this number as x.
The first direction is to add 10 to it which is now x+10
After, we divide this by 6 getting -8.
This would look like (x + 10)/y = -8
Now, we solve
We go backwards so first step Is to multiply -8 by 6. This would get us -48. Then we subtract 10 since we added ten in the first place giving us -58.
The final answer is -58
Answer:
The original number was -58
Step-by-step explanation:
Step 1: Do -8*6 to find out what the numerator was.
Step 2: After finding that the numerator was -48 you would subtract 10 getting -58
Step 3: Check your work : -58+10 = -48
-48/6 = -8
