Answer:

0.0076260072727272727272727272....

Step-by-step explanation:

78125*55*x=32768

x=0.007626007272

If you were asking for (5⁷)(55)x= $5^{8}$ though,

$5^{7} *55$ can be rewritten as $5^{8} * 11$

Therefore, $5^{8} *11*x=5^{8}$

and x= $\frac{1}{11}$

Calculate

$\sf\longmapsto4296875x=32768$

Divide both sides by 4296875

$\sf\longmapsto \dfrac{4296875x}{4296875} = \dfrac{32768}{4296875}$

Answer

$\sf\longmapsto \: x = \dfrac{32768}{4296875}$

A fine fabric was selling for $10.50 per half yard. Joni bought 2 1/3 yards. How much did he spend? Brainliest for correct answe

gregori [183]

Answer:

$49 is spended by him.

solution given:

rate=for $10.50 per half yard=$10.50/0.5=$21 per yard

area=2 1/3=7/3yards

now

total cost =rate× area =$21×7/3=$49

A total of 17,100 seats are still available for the next hockey game. If 62% of the tickets are sold, how many seats are in the

MrRa [10]

Answer:

We have

seats x ( 62 / 100 ) = (seats - 17,100);

seats x 62 = 100 x (seats - 17,100);

seats x 62 = seats x 100 - 1710000;

1,710,000 = seats x 38;

seats = 1,710,000 ÷ 38;

seats = 45,000;

The correct answer is c. 45,000 seats;

A random sample of n = 45 observations from a quantitative population produced a mean x = 2.5 and a standard deviation s = 0.26.

oee [108]

Answer:

P-value (t=2.58) = 0.0066.

Note: as we are using the sample standard deviation, a t-statistic is appropiate instead os a z-statistic.

As the P-value (0.0066) is smaller than the significance level (0.05), the effect is significant.

The null hypothesis is rejected.

There is enough evidence to support the claim that the population mean μ exceeds 2.4.

Step-by-step explanation:

This is a hypothesis test for the population mean.

The claim is that the population mean μ exceeds 2.4.

Then, the null and alternative hypothesis are:

$H_0: \mu=2.4\\\\H_a:\mu> 2.4$

The significance level is 0.05.

The sample has a size n=45.

The sample mean is M=2.5.

As the standard deviation of the population is not known, we estimate it with the sample standard deviation, that has a value of s=0.26.

The estimated standard error of the mean is computed using the formula:

$s_M=\dfrac{s}{\sqrt{n}}=\dfrac{0.26}{\sqrt{45}}=0.0388$

Then, we can calculate the t-statistic as:

$t=\dfrac{M-\mu}{s/\sqrt{n}}=\dfrac{2.5-2.4}{0.0388}=\dfrac{0.1}{0.0388}=2.58$

The degrees of freedom for this sample size are:

$df=n-1=45-1=44$

This test is a right-tailed test, with 44 degrees of freedom and t=2.58, so the P-value for this test is calculated as (using a t-table):

$P-value=P(t>2.5801)=0.0066$

As the P-value (0.0066) is smaller than the significance level (0.05), the effect is significant.

The null hypothesis is rejected.

There is enough evidence to support the claim that the population mean μ exceeds 2.4.
