Answer:

C. 2/3

Step-by-step explanation:

p(event) = (number of desired outcomes)/(total number of outcomes)

The total number of outcomes is the sum of the numbers of all chips.

5 + 3 + 7 = 15

The desired outcomes are any red or blue chips to be drawn.

There are 3 red chips and 7 blue chips.

3 + 7 = 10

Number of desired outcomes = 10

p(red or blue) = 10/15 = 2/3

Answer: C. 2/3

If the correlation between height and weight of a large group of people is 0.75​, find the coefficient of determination​ (as a​
Shtirlitz [24]
Independent variable is the predictor variable which is the height and dependent variable is the response variable which is weight in this scenario.

The square of correlation coefficient gives the coefficient of determination. It is denoted by R² (R squared).

We are given:
R = 0.75

So,
R²  = 0.75²

R² = 0.5625

R²  = 56.25 %
The coefficient of determination tells how much of the trend of dependent data can be explained by the independent data using the linear regression model. So in the given case, Height can explain 56.25% of the trend in the weight.

Divide each side by 5

ky -6 = 3y -6

Add 6 to each side
