Answer:

  C.  3/10 * 2/5

Step-by-step explanation:

3 of the 10 horizontal stripes are colored orange, representing a fraction of 3/10.

2 of the 5 vertical stripes are colored purple, representing a fraction of 2/5.

The area of overlap is 6 of the 50 small boxes, so represents the product ...

  3/10 * 2/5 = 6/50

trapecia [35]

Answer:

The p-value is significantly low(<0.01), which means that the data provides convincing evidence that the true mean advertisement length is longer than 45 seconds.

Step-by-step explanation:

An online streaming service providing television programs claims that a 30-minute program will stream with advertisements that average 45 seconds. Test if the true mean advertisement length is longer than 45 seconds.

At the null hypothesis, we test if the mean time is of 45 seconds, that is:

H_0: \mu = 45

At the alternate hypothesis, we test if the mean is more than 45 seconds, that is:

H_1: \mu > 45

The test statistic is:

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, s is the standard deviation and n is the size of the sample.

45 is tested at the null hypothesis:

This means that \mu = 45

They recorded the times of 21 randomly selected advertisements. The mean and standard deviation for these times are 46.67 and 2.78.

This means that n = 21, X = 46.67, s = 2.78

Value of the test-statistic:

t = \frac{X - \mu}{\frac{s}{\sqrt{n}}}

t = \frac{46.67 - 45}{\frac{2.78}{\sqrt{21}}}

t = 2.75

P-value of the test and decision:

The p-value of the test is the probability of finding a sample mean above 46.67, which is a right-tailed test, with t = 2.75 and 21 - 1 = 20 degrees of freedom.

With the help of a calculator, this p-value is of 0.0062.

The p-value is significantly low(<0.01), which means that the data provides convincing evidence that the true mean advertisement length is longer than 45 seconds.

Could someone help me answer this? <br> Solve -2log8(x + 1) = -8.<br> Thanks so much!
drek231 [11]
Step one, divide both sides by -2
log8(x+1)=4

if the base is 10, and the 8 is together with (x+1): (cannot tell from the way it is written)
8(x+1)=10^4=10000
x+1=1250
x=1249

if the 8 is a base, 
8^4=(x+1)
x+1=4096
x=4095

Super confused definitely need help on this
Marat540 [252]

Answer:

(x-5)(x+8)=x^2+3x-40

Step-by-step explanation:

So we have the expression:

(x-5)(x+8)

To multiply, distribute the left to the terms on the right:

=(x-5)(x)+(x-5)(8)

Distribute:

=(x^2-5x)+(8x-40)

Combine like terms:

=(x^2)+(-5x+8x)+(-40)

Simplify:

=x^2+3x-40

Therefore:

(x-5)(x+8)=x^2+3x-40
