Sladkaya [172]

Answer:

2.60

Step-by-step explanation:

z-score is the difference between the score and mean, divided by the standard deviation.

$z = \frac{x - \mu}{\sigma}$

$z = \frac{91-77.5}{5.2} = \frac{13.5}{5.2} \approx 2.596$

So 2.6 is an answer close enough.

Find the value of x round to the nearest tenth

zzz [600]

Answer:

4.1 cm

Step-by-step explanation:

The segment marked x bisects the chord, so the triangle shown has legs x and 7.8, and hypotenuse 8.8.

The Pythagorean theorem can be used to find x:

8.8² = x² +7.8²

x² = 8.8² -7.8² = 77.44 -60.84 = 16.60

x = √16.6

x ≈ 4.1 . . . cm

If the length of a rectangular field is twice the width and the perimeter is 24. Write an equation that an be used to solve for

Sedbober [7]

If we use the width as x we have 2x with both widths and 4x with both lengths. So 6x=24 and x=4. So length is 8 and width is 4.

What is the slope of the line on the graph? Enter your answer in the box. A coordinate grid that includes the line y equals nega

RUDIKE [14]

we have

the equation of the line is $y=-2x$

the points are

$A(3,-6)\\B(0,0) \\C(-3,6)$

Method 1

we know that

A relationship between two variables, x, and y, represent a direct variation if it can be expressed in the form $y/x=k$ or $y=kx$

In this problem we have a direct variation

The constant of proportionality k is equal to the slope of the line

$k=-2$

$m=-2$

therefore

the answer is

the slope of the line is equal to

$m=-2$

Method 2

we know that

the formula to calculate the slope between two points is equal to

$m=\frac{y2-y1}{x2-x1}$

we have

$A(3,-6)\\B(0,0)$

substitute in the formula

$m=\frac{0+6}{0-3}$

$m=\frac{6}{-3}$

$m=-2$

therefore

the answer is

the slope of the line is equal to

$m=-2$
