In analyzing statistical data, which do you think is more likely: a correlation coefficient of 0.9 or a correlation coefficient

of 1.0? Explain.
Imagine that you have plotted many data points on an xy-plane. Your points seem to align into a clear best-fit line. Do you think this best-fit line can help you make predictions about future data? Explain your answer, and give one or more examples to support it.

You're studying how well students remember vocabulary after they stop studying a new language. The first student you study remembers 95% of the French words she learned 3 months later, but only 70% of the words 12 months later.

Before studying more students, you wonder: Is a decreasing linear model or an exponential decay model likely to be a better fit for data about remembering? Decide which model you think will be better. Explain your reasoning.

Triangles MNQ and MOP are similar. What is the slope of segment MO?
asambeis [7]

Answer:

D. 3/2

Step-by-step explanation:

The scale factor is 1/2 from OP / NQ = 1/2. Because of that, MQ is equal to half of MP and QP is equal to half of MP. Therefore, QP = MQ = 2. The slope of MO is rise over run which is 6 / 4 or 3 / 2.

Wes works at a science lab that conducts experiments on bacteria. The population of the bacteria multiplies at a constant rate,
Dmitry [639]

Answer:

Correct answer: at 2 p.m. the population was 10,000

                          at 3 p.m. the population was 50,000

Step-by-step explanation:

At 1 p.m. population was 2,000

At 2 p.m. or after  first hour, the population of bacteria increases

in this way 2,000 · k  

At 3 p.m. or after second hour, the population of bacteria increases

2,000 · k²

At 4 p.m. or after third hour, the population of bacteria increases 2,000 · k³

2,000 · k³ = 250,000 =>  k³ = 250,000 / 2,000 = 125

k = ∛125 = 5  => k = 5

At 2 p.m. or after  first hour, the population of bacteria was 2,000 · 5 = 10,000

At 3 p.m. or after second hour, the population of bacteria was 2,000 · 5² =

= 2,000 · 25 = 50,000

Please help, it’s due today :)

Answer:

x =5

Step-by-step explanation:

We can use ratios for the side lengths

9              x

--------- = -----------

9+18       x+10

Using cross products

9 (x+10) = x * (9+18)

Distribute

9x+90 = x*27

9x+90 = 27x

Subtract 9x from each side

9x-9x+90 = 27x-9x

90 = 18x

Divide each side by 18

90/18 = 18x/18

5 =x
