Kadesha says that the triangles represent a translation. Which explains whether Kadesha is correct?


A. Kadesha is correct because triangle ABC is the pre-image and triangle A' B' C' is the image.

B. Kadesha is correct because each point in triangle ABC moves five units up.

C. Kadesha is not correct because the number of units between points A and B is different than those between points A' and B'.

D. Kadesha is not correct because a translation is a horizontal movement.

Answers

Answer:

C

Step-by-step explanation:

C is correct because a translation is just a movement across the graph- but in this case, the shape has not just moved, but the space between the points has changed. In a translation, the shape does not change at all.

For B: You're trying to get to 60, not 45.

For C: Same thing as A: +7.5 is not equal to x 2.

Therefore, D is correct :D

7 is the largest stem and 9 is the largest leaf on that stem

there are only 3 leaves greater than 30 but under 40 they are 31, 31, and 39

Chloe is drinking 3/5 cup of water every 6 minutes. How many cups will they drink in 2 hours?

Answers

Answer:

12 cups

Step-by-step explanation:

One of the easiest ways to solve this problem is to first turn the fraction into a decimal. 3/5=0.6

The second step is to see how much water Chloe drinks in an hour. Since there are 60 minutes in an hour and 6 times 10 is 60, we do 0.6 times 10 to see how much water Chloe drinks in one hour. 0.6x10=6

The third and final step is to double 6. We do this because 6 is how many cups of water Chloe drinks in one hour, but we need to find two. 6x2=12.

Therefore, Chloe would drink 12 cups of water in 2 hours.

Answer:

Step-by-step explanation:

12 cups. You have to divide 120 by 6, then you divide that answer (20) by 3/5, which is 0.6 in decimal form, your answer should be 12 cups of water.

The scatter plot below shows the average traffic volume and average vehicle speed on a certain freeway for 50 days in 1999.
Which statement best describes the relationship between average traffic volume and average vehicle speed shown on the scatter plot?

As traffic volume increases, vehicle speed increases at first, then decreases.
As traffic volume increases, vehicle speed decreases at first, then increases.
As traffic volume increases, vehicle speed increases.
As traffic volume increases, vehicle speed decreases

Answers

as traffic volume increases, vehicle speed decreases!

Traffic Volume and vehicle speed are negatively correlated that means that  as the  traffic volume increases , the vehicle speed will decrease.

What is negative correlation in scatter plot?

When the points in the scatter plot are in the pattern of falling from left to right it means the data is negatively correlated ,It means that the value of one variable decreases when the value of another variable increases.

Or we can say that the variable over x axis increases then variable for y - axis decreases.

As shown in the scatter plot in  the question , we can that the points are falling from left to right , therefore there must be negative correlation

between Average traffic Volume And Average Vehicle speed.

Therefore, as the traffic volume increases , the vehicle speed will decrease.

Suppose you know that ∠S and ∠Y are complementary, and that m∠S = 5(m∠Y) − 150°. Find m∠Y.

Answers

Answer:

∠s + ∠y are complementary

∴ ∠s + ∠y = 90°

∠s = 4(∠y ) -100

s + y = 90

4y - 100 + y = 90

5y = 90 + 100

5y = 190

y = 38

Ans: y = 38°

For each frog, the temperature of its habitat (in degrees Celsius) and the frequency of its mating call (in tones per second) are recorded. The 96 percent confidence interval for estimating the population slope of the linear regression line predicting mating call frequency based on habitat temperature is given by 2.3410.768. Assume that the conditions for inference for the slope of the regression line have been met. Which of the following is the correct interpretation of the calculated confidence interval?a. We are 96 percent confident that the increase in mating call frequency of an individual frog when its habitat temperature increases by 1 degree Celsius is between 1.573 and 3.109 tones per second. b. We are 96 percent confident that the average increase in mating call frequency in the sample of frogs when habitat temperature increases by 1 degree Celsius is between 1.573 and 3.109 tones per second. c. We are 96 percent confident that the average increase in mating call frequency in the population of frogs when habitat temperature increases by 1 degree Celsius is between 1.573 and 3.109 tones per second. d. We are 96 percent confident that the average increase in habitat temperature in the sample of frogs when mating call frequency increases by one tone per second is between 1.573 and 3.109 degrees Celsius. e. We are 96 percent confident that the average increase in habitat temperature in the population of frogs when mating call frequency increases by one tone per second is between 1.573 and 3.109 degrees Celsius.
