Answer:

x = $59.85

Step-by-step explanation:

100% = $63

95% = x

100x = 95*63

100x = 5985

x = $59.85

Answer:

x = 2

Step-by-step explanation:

note that 4096 = $8^{4}$ , then

$8^{2x}$ = $8^{4}$

Since bases on both sides are equal, both 8 , then equate the exponents

2x = 4 ( divide both sides by 2 )

x = 2

the width of a rectangle is half as long as the length. The rectangle has an area of 98 square feet. What are the length and wid

Andrews [41]

Let's call them: W and L

Then area: A = W × L

We can replace: L = 2 × W

So: A = W × 2W=98→

2W^2=98 →W^2=98/2=49

→W=√49=7

→L=2×W=2×7=14

Conclusion: The rectangle is 7*14 ft

Hope this helps :)

The paint used to make lines on roads must reflect enough light to be clearly visible at night. Let μ denote the true average re

tatuchka [14]

Answer:

We conclude that average reflectometer reading for a new type of paint is greater than 20

Step-by-step explanation:

We are given the following in the question:

Population mean, μ = 20

Sample size, n = 13

Alpha, α = 0.05

First, we design the null and the alternate hypothesis

$H_{0}: \mu = 20\\H_A: \mu > 20$

Formula:

$t_{stat} = \displaystyle\frac{\bar{x} - \mu}{\frac{\sigma}{\sqrt{n}} } = 3.2$

Degree of freedom = n - 1 = 13 - 1 = 12

Now, we calculate the p-value with the help of standard table.

P-value = 0.004

Since, the p-value is less than the significance level, we fail to accept the null hypothesis and reject it.

Thus, there is enough evidence to support that average reflectometer reading for a new type of paint is greater than 20
