Answer:

  (1/2, 0), (0, -2)

Step-by-step explanation:

We can determine the slope from ...

  slope = (change in y)/(change in x) = (10 -2)/(3 -1) = 8/2 = 4

Then an equation for the line can be written for slope m and point (h, k) as ...

  m(x -h) -(y -k) = 0

Using the slope we calculated and the first point, we have the equation ...

  4(x -1) -(y -2) = 0

  4x -4 -y +2 = 0 . . . . . eliminate parentheses

  4x -y = 2 . . . . . . . . . . put in standard form

Now, we can divide by the constant on the right to put this into intercept form:

  x/(x-intercept) + y/(y-intercept) = 1

  x/(1/2) + y/(-2) = 1

The x-intercept is 1/2; the y-intercept is -2.

In science class, the students observed 24 of the 300 frogs from the local aquarium. If 6 of the frogs observed had spots, how m
Alona [7]

Answer:

225 frogs

Step-by-step explanation:

Total population of frogs = 300 frogs.

Observed population of frogs = 24

6 of the 24 observed frogs had spots

Which means , the number of frogs that did not have spots = 24 - 6 = 18 frogs.

We were told to find how many of the total population can be predicted to NOT have spots. We would form a proportion.

If 24 frogs = 18 frogs with no spots

300 frogs = Y

Cross multiply

24Y = 300 × 18

Y = (300 × 18) ÷ 24

Y = 5400 ÷ 24

Y = 225 frogs.

This means out of 300 frogs, 225 frogs do not have spots.

Therefore, the total population that can be predicted to NOT have spots is 225 frogs.

the total population can be predicted to NOT have spots

General formula for a simple linear regression :

y = ab + c

Where ;

y = predicted variable ; a = slope / gradient

b = predictor / independent variable ; c = intercept

From the result obtained from the calculator :

y = -0.01246X + 74.65552

Correlation Coefficient is used to measure the strength of relationship between linear variables.

The regression Coefficient obtained is - 0.20

This shows that there is a weak negative correlation between the age at auction and the price at which painting is sold. This is because the negative sign means that value of y decreases as x increases or vice versa, however, due to a correlation vale which is closer to 0 than 1 or - 1, we can conclude that the negative relationship between the variables is weak.
