You are analyzing a scatter plot that has a negative correlation. What is true of the of the x and y values?

Answers

Answer:

As x increases, y decreases

Correlations on a scatter plot can either be positive or negative. When it has a negative correlation, it means the x values increases as the y values decreases.

There are basically two types of correlation on the scatter plot

Positive correlationNegative correlation

A positive correlation is such that as x increases, y also increases.

However, a negative correlation is such that as x increases, y decreases.

Hence, we can conclude that the x and y values of a scatter plot with negative correlation are in opposite direction.

See attachment for a scatter plot with negative correlation.

Select the TWO expressions that are greater than 3.

Answers

Answer:

1.67 + 1.4 = 3.07

2.97 + 0.004 = 2.974

3.017 - 0.05 = 2.967

5.503 - 2.52 = 2.983

1.67 + 1.4, and 4.5 - 1.47 are the two expressions that are greater than 3.

1.67 + 1.4 = 3.07

SAME SCENARIO - DIFFERENT QUESTION

Eliza intends to buy a new vehicle. She wishes to estimate the average fuel efficiency (in miles per gallon) of all family sized SUVs currently available on the market. Eliza selects a random sample of 15 family sized SUVs on the market and looks up their fuel efficiency on a trusted website. The results of the random sample are shown below:

27, 28, 30, 28, 28, 31, 29, 33, 28, 28, 31, 33, 41, 41, 25

If Eliza were to take another random sample of 15 SUVs from the same population, would she be likely to get the exact same value for the mean?

Question 2 options:

Yes, it is likely that Eliza will get the exact same value for the sample mean


No, it is not likely that Eliza will get the exact same value for the sample mean

plz help i will give brainliest

Answers

First what your gonna do is find the slope. So y2-y1/x2-x1 so 17-12/220-120= 5/100 so 1/20. Then you have to put that into slope intercept form. So y=1/20x + b. Then plug in points for x and y. I’ll use 12 and 120. So 12 = 1/20(120)+ b = 12=6+b then subtract 6 from both sides to get b= 6. So your answer is y= 1/20x +6

Answer:

18 dimes, 12 quarters

Step-by-step explanation:

We are to solve the system of linear equations for D and Q, where D is the number of dimes and Q is the number of quarters.

Each dime is worth $0.10 and each quarter $0.25.  Thus, D dimes are worth ($0.25/dime)D and Q quarters ($0.25/quarter)Q.

The sum of D and Q comes out to 30 coins, a mixture of dimes and quarters:  D + Q = 30, so Q = 30 - D.  

Now let's solve this equation:  ($0.10/dime)D + ($0.25/quarter)Q = $4.80.

Substitute 30 - D for Q:

($0.10/dime)D + ($0.25/quarter)(30 - D) = $4.80

This is now entirely in D (no Q shows up).  Performing the indicated multiplication, we get 0.10D + 0.25(30) - 0.25D = 4.80

Combining like terms:  0.10D - 0.25D = -0.15D, and -7.5 + 4.80 = -2.7

Thus, -0.15D = -2.70, and so D = 2.70/0.15 = 18 (There are 18 dimes.)

Since Q = 30 - D, and D - 18, Q = 30 - 18 = 12 (There are 12 quarters)

18 dimes and 12 quarters ..........
