Answer:

c=-16

Step-by-step explanation:

we have

-\frac{1}{8}c=2

solve for c

That means-----> isolate the variable c

Multiply by -8 both sides

-\frac{1}{8}c(-8)=2*(-8)

Simplify

c=-16

Write an equation of the line below​
Ratling [72]

Answer:

y = 3/5 + 4

Step-by-step explanation:

Given Coordiantes:

(0,4) - Y-intercept

(5,7) - Coordinates

To make an equation, first find the slope.

m=\frac{rise}{run} =\frac{y}{x}

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

m=\frac{7-4}{5-0}

m=\frac{3}{5}

In decimals:

m = 0.6

Now convert to point slope.

y-y_{1} =m(x-x_{1} )

y-4=\frac{3}{5} (x-0)

In decimals:

y-4=0.6(x-0)

Now convert to slope-intercept form.

Find the Equation of the Line:

y=mx+b

by solving for y using the Point Slope Equation.

y = 3/5 + 4

A desk manufacturer claims that the average time it takes to assemble a desk is 90 minutes with a standard deviation of 32 minut
stealth61 [152]

Answer:

The standard deviation of the sample mean is 4 minutes

Step-by-step explanation:

The Central Limit Theorem estabilishes that, for a normally distributed random variable X, with mean \mu and standard deviation \sigma, the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean \mu and standard deviation s = \frac{\sigma}{\sqrt{n}}.

For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.

In this problem, we have that:

The standard deviation of the population is 32.

Sample of 64.

So

s = \frac{32}{\sqrt{64}} = 4

The standard deviation of the sample mean is 4 minutes

Lindsey is practicing her downhill skiing. Slope A descends 15 vertical feet for every 24 horizontal feet. Slipped B descends 12
soldier1979 [14.2K]

Answer:

She should ski on Slope B because it is steeper

Step-by-step explanation:

Slope A

We need to find the "slope"

15/24 = 5/8  


Slope B

12/16 = 3/4


To compare, we need a common denominator

5/8    3/4*2/2

5/8     6/8

    <

Slope B is steeper because the slope  is greater

She should ski on Slope B because it is steeper
