Answer:
The possibility of rolling a
3
on a fair die and getting tails on a coil is
1
12
. Based on this probability, there are
12
possible outcomes. As only 1 out of 12 possiblities would get this outcome, it is not a likely outcome.
Step-by-step explanation:
The probability of rolling a
3
on a fair die is
1
6
because there is only one
3
out of
6
numbers. The probability of getting tails on a coin is
1
2
because there are
2
possibilities and tails is one of them. To get the probability of rolling a
3
on a fair die and getting tails on a coil, we multiply their probabilities:
1
6
⋅
1
2
=
1
12
There are
12
possiblities because for each of the
6
possibilites for rolling a die, there are
2
possibilites for flipping a coin.

Given the function rule y = 3x + 11, what is the value of x if y = 57
Hint: Make sure you are substituting for the correct variable!
Step-by-step explanation:
3x+11=57
subtract 11 from both sides and you will get this
3x=46
Divide by 3
42/3. 3/3
X=14
Answer:
15.333
Step-by-step explanation:
3x+11=57(y)
reverse the question
so:
57-11=46
46 divided by 3=15.333
so x=15.333

The average annual cost of the first year of owning and caring for a cat is $1,500. A sample of 81 will be used. Based on past studies, the population standard deviation is assumed known with σ = $198. What is the margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat?
Answer:
The margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat is of $43.12.
Step-by-step explanation:
We have that to find our [tex]\alpha[/tex] level, that is the subtraction of 1 by the confidence interval divided by 2. So:
[tex]\alpha = \frac{1 - 0.95}{2} = 0.025[/tex]
Now, we have to find z in the Ztable as such z has a pvalue of [tex]1 - \alpha[/tex].
That is z with a pvalue of [tex]1 - 0.025 = 0.975[/tex], so Z = 1.96.
Now, find the margin of error M as such
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
In which [tex]\sigma[/tex] is the standard deviation of the population and n is the size of the sample.
Sample of 81
This means that [tex]n = 81[/tex]
What is the margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat?
[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]
[tex]M = 1.96\frac{198}{\sqrt{81}}[/tex]
[tex]M = 43.12[/tex]
The margin of error for a 95% confidence interval of the mean cost of the first year of owning and caring for a cat is of $43.12.

x=
m∠=
Answer:
x = 21, m∠A = 23°, the measure of angle in the right = 67°
Step-by-step explanation:
The angles of a triangle sum up to 180°.
Right angles equals to 90°.
Thus, (2x - 19)° + (3x + 4)° + 90° = 180°
=> 5x + 75 = 180
=> 5x = 105
=> x = 21
m∠A=> 2(21) -19 = 23°
the measure of angle in the right=> 3(21) + 4 = 67°

Twenty-four out of the forty pies at a bake sale are coconuts pies. What
percent of the pies are coconut?
Answer:
60%
Step-by-step explanation:
Total number of pies = 40
Number of coconut pies = 24
Percentage of coconut pies :
(Number of coconut pies / total number of pies) * 100%
(24 / 40) * 100%
0.6 * 100%
= 60%
60% of pies are coconut pies

The Wiggins Family ate dinner at a restaurant. The total cost of the meal was $85.60. The family left a 15% tip for the waiter. How much money was the total bill? (Make sure you type your answer using $ and the decimal)
Fast please
Answer:
$98.44
Step-by-step explanation:
You already know how much the actual dinner was so all you have to do is figure out how much 15% of the $85.60 is which is $12.84 meaning that they left a tip of $12.84 for the waiter. Then you would just add the cost of the dinner with the tip to get the total amount they spent. $85.60 + $12.84 = $98.44. So the total amount the Wiggins spent is $98.44

A long year-end status report for work is 134 pages long. You need to print 16 copies for a meeting next week. How much is the paper going to cost for those reports? Paper is sold in reams (500 pages) for $3.53 each. Give your answer to the nearest cent, only for the paper you use (partial reams are OK)
Answer:
The total cost of the copies will be $ 15.14.
Step-by-step explanation:
Given that a long year-end status report for work is 134 pages long, and I need to print 16 copies for a meeting next week, to determine how much is the paper going to cost for those reports if paper is sold in reams (500 pages) for $ 3.53 each the following calculation must be performed:
(134 x 16) / 500 = X
2,144 / 500 = X
4.288 = X
500 = 100
144 = X
144 x 100/500 = X
14,400 / 500 = X
28.8 = X
100 = 3.53
28.8 = X
28.8 x 3.53 / 100 = X
101.664 / 100 = X
1.016 = X
1.016 + (3.53 x 4) = X
1.016 + 14.12 = X
15,136 = X
Therefore, the total cost of the copies will be $ 15.14.
Carefree offers two type of care packages. The food packages sell for 20$ and the game packages sell for 32$. In one day Carefree sold 25 Care packeges. the receipt for those packages totaled 602$ How many of each type of package were sold
Answer:
Number of game package = 16.5
Number of food package = 8.5
Step-by-step explanation:
LET :
Food package = a
Game package = b
a + b = 25 - - - (1)
20a + 32b = 602 - - - (2)
a = 25 - b
Put a = 25 - b into (2)
20(25 - b) + 32b = 602
500 - 20b + 32b = 602
12b = 102
b = 102 / 12
b = 8.5
a = 25 - b
a = 25 - 8.5
a = 16.5
Number of game package = 16.5
Number of food package = 8.5

A rectangular park is 70 meters wide and 100 meters long.
Give the length and width of another rectangular park that has the same perimeter but a smaller area.
9514 1404 393
Answer:
60 m wide and 110 m long
Step-by-step explanation:
The more the shape deviates from a square, the smaller the area will be. The area can be reduced by making the park longer and narrower. The sum of length and width must remain the same for the perimeter to be unchanged.
Given park: 70 m × 100 m = 7000 m²
Smaller park: 60 m × 110 m = 6600 m² -- less area than 7000 m²
