Answer:

2 weeks

Step-by-step explanation:

 8 + 2x = 6 + 3x

<u>-6</u>          <u> -6</u>

2   + 2x = 0  + 3x

The tuft bind strength of a synthetic material used to make carpets is known to have a mean of 100 lb and standard deviation of
emmasim [6.3K]

Answer:

The null hypothesis is: H_{0}: \mu = 100

The alternative hypothesis is: H_{a}: \mu > 100

Step-by-step explanation:

At the null hypothesis, we test if the mean is equal to a certain value.

At the alternate hypothesis, we test if the mean is less than, more than, or different from the value tested at the null hypothesis.

The tuft bind strength of a synthetic material used to make carpets is known to have a mean of 100 lb and standard deviation of 20 lb.

This means that the null hypothesis is: H_{0}: \mu = 100

Could it be that the average tuft strength is above 100 lb?

The world above means that the appropriate alternative hypothesis is: H_{a}: \mu > 100

The formula for the volume of a sphere is. What is the formula solved for r?
nataly862011 [7]

Answer:

r = \sqrt[3]{\dfrac{3V}{4 \pi}}

Step-by-step explanation:

V = \dfrac{4}{3}\pi r^3

\dfrac{4}{3}\pi r^3 = V

\pi r^3 = \dfrac{3V}{4}

r^3 = \dfrac{3V}{4 \pi}

r = \sqrt[3]{\dfrac{3V}{4 \pi}}
