Answer:

Radius is 43/π

Step-by-step explanation:

<u>Circumference of a circle:  C = 2πr</u>

<u />

<u>Step 1:  Solve for r</u>

86 / 2π = 2πr / 2π

<em>43/π = r</em>

<em />

Answer:  Radius is 43/π

How do you write <br><br> 40/25<br> as a percentage?
rosijanka [135]
<span>What percent of 40 is 25? 
Let x = what percent 
of = multiplication 
is means = 
We now write it in math terms: 
x times 40 = 25 

40x = 25 
Divide both sides by 40 to find x. 
x = 25/40 
x = 0.625 
Change the decimal number 0.625 to a percent. 
x = 62.5%

1000 views=£2<br> how many views are required to make £31?
dedylja [7]
1000 = £2
10 x 1000 = 10,000 = £20
15,000 = £30
16,000 = £32
Not sure if you want specifically 31 but I’d say if you do it would be 15,000 views

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
