Savannah bought barn wood for $60 for 5 pieces. She spent $40 on materials to paint

Kisachek [45]

Her profit per each wood is $5 so her total profit is $25

because
60 divided by 5 is 12, so each wood is 12 dollars
she spent 40 dollars on materials so 40 divided by 5 is 8, so she spent $20 on each piece of wood to paint it because 12(price of wood)+8(cost of materials per wood)= 20
and shes sells them for 25
so 25-20=5
5x5=25
so the answer is $25 profited

All of the following expressions have the same value except

MrMuchimi

Answer:

1 - 4/5-(-1/5)

Step-by-step explanation:

1. - 4/5-(-1/5)

= -0.8+0.2 (if there is a minus sign inside and outside of the parenthesis, when we destroy that parenthesis, both the minus signs will be multiplied and becomes a (+).) (Making it to the percentile).

= -0.6

2. - 4/5-1/5

= -0.8-0.2

= -1

3. -(4/5+1/5)

= -(0.8+ 0.2) (Making those to the percentile).

= -(1) = -1 (When we destroy the parenthesis, if there is a minus sign outside the parenthesis, the result will become a minus.)

From the above expressions, we can see that after calculating, the second and third expressions have the same value, i. e. -1. However, the result of the first expression is different, and we get -0.6. So option one is the right choice.

The manager of a grocery store has selected a random sample of 100 customers. The average length of time it took these 100 custo

SSSSS [86.1K]

Answer:

The 95% confidence interval would be given by (2.804;3.196)

Step-by-step explanation:

Previous concepts

A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".

The margin of error is the range of values below and above the sample statistic in a confidence interval.

Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".

$\bar X=3.0$ represent the sample mean

$\mu$ population mean (variable of interest)

$\sigma=1$ represent the population standard deviation

n=100 represent the sample size

The confidence interval for the mean is given by the following formula:

$\bar X \pm z_{\alpha/2}\frac{\sigma}{\sqrt{n}}$ (1)

Since the Confidence is 0.95 or 95%, the value of $\alpha=0.05$ and $\alpha/2 =0.025$ , and we can use excel, a calculator or a table to find the critical value. The excel command would be: "=-NORM.INV(0.025,0,1)".And we see that $z_{\alpha/2}=1.96$

Now we have everything in order to replace into formula (1):

$3.0-1.96\frac{1}{\sqrt{100}}=2.804$

$3.0+1.96\frac{1}{\sqrt{10}}=3.196$

So on this case the 95% confidence interval would be given by (2.804;3.196)
