Applying pythagorean theorem:-

$\\ \sf\longmapsto 8^2-5^2=b^2$

$\\ \sf\longmapsto 64-25=b^2$

$\\ \sf\longmapsto b^2=39$

$\\ \sf\longmapsto b=\sqrt{39}$

$\\ \sf\longmapsto b=6.24$

Construct a linear equation for the linear data presented in the table

yaroslaw [1]

Answer:

y = -7x

Explanation:

Take two points from table: (-4, 28), (-3, 21)

Find slope:

$\sf slope: \dfrac{y_2 - y_1}{x_2- x_1} \ \ where \ (x_1 , \ y_1), ( x_2 , \ y_2) \ are \ points$

$\rightarrow \sf slope\ (m): \dfrac{21-28}{-3-(-4)} = -7$

Now find equation:

$\sf y - y_1 = m (x - x_1)$

$\rightarrow \sf y - 21 = -7(x - (-3))$

$\rightarrow \sf y = -7(x +3) + 21$

$\rightarrow \sf y = -7x -21 + 21$

$\rightarrow \sf y = -7x$

A student is finding the measures of the angles in a triangle that have the ratio 4:4:7. Find the mistake and correct it.

7nadin3 [17]

suppose 4:4:7 be 4x, 4x, 7x

or, 15x = 180°

or, X = 180/15

or, X = 12

therefore,

4x = 4x12= 48

4x= 4x12= 48

7x= 7x12= 84

so if you plus all of them you get 180

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
