Answer:
They are congruent bc they are the same size and shape
Answer:
Congruent by SAS
Step-by-step explanation:
As given by the diagram, we have two congruent sides already. From the set of parallel lines, we see that two angles are congruent because they are corresponding. Luckily, this angle falls between the two congruent sides, which gives you the proof of SAS.

Fint the are and perimeter of the shape at the bottom
Answers
Answer:
Area: 59.5 ft squared
Perimeter: 31.6 feet
Step-by-step explanation:
Area:
For the area of the square, you're going to use the formula length times width. The length and width are both 7, so you'll do 7 times 7, which is 49. Next, you need to find the area of the triangle. It's a bit more confusing since they give you the hypotenuse (7.6 ft), but they did that to try and trick you. The area of a triangle is length times width divided by two. So, you're going to take the width (3) and multiply it by the length (7). The length is 7 because the length of the square and the triangle are the same since the bottom of the triangle is the same length as the top of the square. Anyway, using the formula, you will do 7 times 3 divided by 2, which is 21 divided by 2, which is 10.5. Add the 10.5 to the 49 we got from the square, and you'll get 59.5 feet squared.
Perimeter:
For the perimeter, you just need to add the side lengths. Starting at the top and going to the right, we can add 7.6+7+7. We don't get the left length, but it's the same as the rest of the square (7) because all sides of a square are equal. So, now we have 7.6+7+7+7, which is 28.6, and we just need the last one which is 3, so the final answer is 31.6 feet.
Answer:
Area: 59.5 ft squared
Perimeter: 31.6 feet

A sample of 2,500 people was asked how many cups of coffee they drink in the morning. You are given the following sample information. Cups of Coffee Frequency 0 700 1 900 2 600 3 300 2,500 Refer to Exhibit 5-7. The variance of the number of cups of coffee is _____.
Answers
Answer: V(X) = 0.96
Step-by-step explanation: Variance is defined as the average of the squared difference from the sample or population mean.
For a discrete frequency distribution is calculated following the steps:
1) Determine expected value or mean:
[tex]E(X)=\frac{\Sigma xf}{\Sigma f}[/tex]
[tex]E(X)=\frac{0(700)+1(900)+2(600)+3(300)}{2500}[/tex]
E(X) = 1.2
2) Multiply frequency and the squared difference of x and expected value:
[tex]f(x-E(X))^{2}[/tex]
[tex]700(0-1.2)^{2}=1008\\900(1-1.2)^{2} = 36\\600(2-1.2)^{2} = 384\\300(3-1.2)^{2} = 972[/tex]
3) Add them:
[tex]\Sigma [f(x-E(X))^{2}][/tex] = 1008 + 36 + 384 + 972 = 2400
4) Divide the sum per frequency total:
[tex]V(X)=\frac{\Sigma [f(x-E(X))^{2}]}{\Sigma f}[/tex]
[tex]V(X)=\frac{2400}{2500}[/tex]
V(X) = 0.96
The variance of the number of cups of coffee is 0.96.

Mrs. Dimitri purchased a case of yogurt cups. Out of every 10 yogurt cups, 6 are strawberry. There are 30 yogurt cups in the case. How many yogurt cups are strawberry?
Answers
Answer:
18
Step-by-step explanation:
The ratio of strawberry yogurt cups to all of the yogurt is 6:10. We know that there are 30 total yogurt cups, which is the same as 3 times 10. to find the number of strawberry cups, 6 should be multiplied by 3 as well to equal 18. 18:30 is still the same ratio as 6:10
Michael can mow 5 lawns in 36 minutes. At this rate, how long will it take him to mow 15 lawns?
Answers
Answer:
It would take him 108 minutes to mow the lawn.
Step-by-step explanation:
We can do proportion.
[tex] \frac{5 \: lawns}{36 \: minutes} = \: \frac{15 \: lawns}{x} [/tex]
[tex]36 \times 15 = 540 \\ 5 \times x = 5x[/tex]
[tex] \frac{540}{5} = \frac{5x}{5} [/tex]
[tex]108 = x[/tex]

Suppose you have two six-sided dice where each side is equally likely to land face up when rolled. What is the probability that you will roll doubles?
Answers
Answer:
1/3 of chance
The probability that you will roll doubles will be 1/36.
What is probability?Probability is defined as the ratio of the number of favourable outcomes to the total number of outcomes in other words the probability is the number that shows the happening of the event.
Probability = Number of favourable outcomes / Number of sample
Given that you have two six-sided dice where each side is equally likely to land face up when rolled.
The favourable outcomes are {2,2} = 1.
Total outcomes = 36
The probability will be calculated as,
Probability = 1 / 36
