1 answer:

8 0

Since you need to find the area of a square napkin, you need to know what the formula for a square is. It is height multiplied by base. So a square is equal in all sides. 8×8=64
Answer: 64 in²

Mr. Hinckley owns 83 acres of land, he divides the land into eight equal sections to sell to eight buyers which phrase describes

anygoal [31]

Alright, lets get started.

Mr. Hinckley owns 83 acres of total land.

He divides the land into eight equal sections to sell to eight buyers.

It means, we could find the land each buyer receives by dividing total land by 8.

So, each buyer receives land = $\frac{83}{8}$

So, each buyer receives land = 10.375 acres

So, the answer is 10.375 acres lands received by each buyer. : Answer

Hope it will help :)

The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.

SVEN [57.7K]

Answer:

n = -3

Step-by-step explanation:

The difference of the square of a number and 24 is equal to 5 times that number. Find the negative solution.

I'm going to call the number "n."

n² - 24 = 5n subtract 5n from both sides to get the equation equal to zero

- 5n -5n

n² - 5n - 24 = 0 factor the trinomial into the multiplicatin of two binomials

we need factors (numbers that multiply) to -24 that add up to

-5. The only factors for -24 that will add up to -5 are -8 and 3.

(n-8)(n+3) = 0 set each binomial equal to zero and solve for n

n-8 = 0 or n+3 = 0

+8 +8 -3 -3

n = 8 or n = -3 n = -3 is the negative solution

. You are interested in the amount of time teenagers spend weekly working at part-time jobs. A random sample of 15 teenagers was

agasfer [191]

Answer:

$t=\frac{147.3-120}{\frac{50}{\sqrt{15}}}=2.115$

Now we can calculate the degrees of freedom

$df=n-1=15-1=14$

If we find a critical value in the t distribution with 14 degrees of freedom who accumulates 0.05 of the area in the right we got $t_{critc}= 1.761$

Since the calculated value is higher than the critical value we have enough evidence to conclude that the true mean is significantly higher than 120 minutes for the average time of part time jobs

Step-by-step explanation:

Information given

$\bar X=147.3$ represent the sample mean for the amount of time spent at part time jobs

$s=50$ represent the sample standard deviation

$n=15$ sample size

$\mu_o =120$ represent the value to check

$\alpha=0.05$ represent the significance level

t would represent the statistic

$p_v$ represent the p value for the test

System of hypothesis

We want to analyze if the true mean for the amount of time spent at part time jobs is higher than 120, the system of hypothesis would be:

Null hypothesis: $\mu \leq 120$

Alternative hypothesis: $\mu > 120$

Since we don't know the population deviation the statistic is given by:

$t=\frac{\bar X-\mu_o}{\frac{s}{\sqrt{n}}}$ (1)

Replacing the info given we got:

$t=\frac{147.3-120}{\frac{50}{\sqrt{15}}}=2.115$

Now we can calculate the degrees of freedom

$df=n-1=15-1=14$

If we find a critical value in the t distribution with 14 degrees of freedom who accumulates 0.05 of the area in the right we got $t_{critc}= 1.761$

Since the calculated value is higher than the critical value we have enough evidence to conclude that the true mean is significantly higher than 120 minutes for the average time of part time jobs
