A bag contains 22 coins consisting of quarters and nickels. The total value of the coins is $3.90. How many nickels are in the b
bezimeni [28]

Answer:

8 Nickels

Step-by-step explanation:

Since a Nickel is worth 5 cents ($0.05)

And a Quarter is worth 25 ($0.25)

and theres 22 coins

8 of those coins would be nickels which would mean we add 8 nickels up

8 x 0.05 = 0.4

then we add the quarters up

14 x 0.25 = 3.5

3.5 + 0.4 = $3.90

For a sample of eight​ bears, researchers measured the distances around the​ bears' chests and weighed the bears. Minitab was us
ExtremeBDS [4]

Answer:

There is a linear correlation between chest size and weight,0.8482

Step-by-step explanation:

Given that for a sample of eight​ bears, researchers measured the distances around the​ bears' chests and weighed the bears.

the value of the linear correlation coefficient is r = 0.921.

i.e. there is a strong positive correlation from the value of r.

H_0: r=0\\H_1: r\neq 0

(Two tailed test at 5% level for correlation coefficient)

Test statistic t = \frac{r\sqrt{n-2 } }{\sqrt{1-r^2}} \\=5.791

p value <0.00001

Since p is less than 0.05 we reject H0

a) There is a  linear correlation between chest size andweight

b)--  R^2 = 0.8482 proportion of the variation in weight can be explainedby the linear relationship between weight and chest size

Find the equation of the line passing through the points (0,7) and (5,-3). <br>​
Dennis_Churaev [7]

Answer:

y = - 2x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = \frac{y_{2}-y_{1}  }{x_{2}-x_{1}  }

with (x₁, y₁ ) = (0, 7 ) and (x₂, y₂ ) = (5, - 3 )

m = \frac{-3-7}{5-0} = \frac{-10}{5} = - 2

The line crosses the y- axis at (0, 7 ) ⇒ c = 7

y = - 2x + 7 ← equation of line
