Answer:
x = 7.423891441
Step-by-step explanation:
Hey There!
So they want you to solve for x using law of sines
Law of sines states that sin ( an angle) divided by it's opposite side equals sin( a different angle) divided by its opposite side
so basically
[tex]\frac{sin23}{x} =\frac{sin90}{19}[/tex]
now we can solve for x
step 1 multiply each side by sin 23
the fraction would split and it would be
[tex]x=\frac{19sin23}{sin90}\\x = 7.423891441[/tex]
So we can conclude that x = 7.423891441

square meter. What is the intensity of light 200 meters below the surface
Answers
9514 1404 393
Answer:
316 lumens/m²
Step-by-step explanation:
We assume your intensity function is ...
f(x) = 50,000(0.975^x) . . . . x meters below the surface
__
Use 200 for x and do the arithmetic.
f(200) = 50,000(0.975^200) ≈ 316 . . . . lumens/m²

Answers
Answer:
8,10,12
Step-by-step explanation:
Answer:
integer 1 = 8
integer 2 = x+2 = 8+2 = 10
integer 3 = x+4 = 8+4 = 12
Step-by-step explanation:
integer 1 = x , smallest
integer 2 = y , x+12
integer 3 = z , largest, x+4
three times the smallest is twice the largest.
3 (x) = 2 (x+4)
solve for x:
3x = 2x + 8
3x-2x = 8
x = 8
Replacing:
integer 1 = 8
integer 2 = x+2 = 8+2 = 10
integer 3 = x+4 = 8+4 = 12

Ninja gym membership costs $33 per month after an initial membership fee. You paid a total of $338 after 5 months. Write an equation that gives you the total cost related to the months of your gym membership.
Answers
To find this you have the equation 33x + m = 338. It tells us that this is after 5 months, so now we put 5 into x and multiply to get 165. Now the equation looks like 165 + m = 338. Subtract 165 from both sides to find m, which leaves us with 173 for the initial fee. Now you just have to rewrite the equation to be 33x + 173 = Total amount

Step-by-step explanation:
Use the point-slope formula for the equation of a straight line:

Bob gets paid an annual salary of $30,000 and earns 5% commission on all sales he makes. If Bob wants to make $6,000 this month, how much in sales does he need to have?
a.
$50,000
b.
$70,000
c.
$90,000
d.
$120,000
Answers
Answer:
The answer is 70,000 sales.
Bob gets paid an annual salary of $30,000, which means that monthly he gets:
$30,000 : 12 months = $2,500 per month
x - number of sales
Bob earns 5% commission on all sales he makes: x * 5% = x * 0.05 = 0.05x
The function is:
f(x) = 2,500 + 0.05x
Bob wants to make $6,000 this month: f(x) = 6,000
2500 + 0.05x = 6000
0.05x = 6000 - 2500
0.05x = 3500
x = 3500 : 0.05
x = 70000 sales
Step-by-step explanation:
Sales for the month should amount to $70,000
Annual salary = $30,000
Commission on sales = 5%
To make 6000 in a month :
Monthly salary = $30000 / 12 = $2500
Month earning = $2500 + 5% × (monthly sales)
Month earning = $6000
Let month sales = m
6000 = 2500 + 0.05m
6000 - 2500 = 0.05m
3500 = 0.05m
m = 3500 / 0.05
m = 70,000
Sales for the month should be 70,000

Two years ago, the average number of customers in your all of your company's stores per week was 3173 customers. This figure had increased 6% over the previous two years. Assume that you are doing a current study to test the claim that the mean weekly number of customers is different than it was two years ago. Assume a population standard deviation of 1,550 customers. Suppose you look at a random sample of 73 stores and find an average weekly customer total of 3,391. You wish to test the claim stated above at the 0.10 level. Run the appropriate hypothesis test.
Required:
Write ONLY the conclusion to your hypothesis test.
Answers
Answer:
Accept the null hypothesis
Step-by-step explanation:
Two years ago, the average number of customers in your all of your company's stores per week was 3173 customers. Assume that you are doing a current study to test the claim that the mean weekly number of customers is different than it was two years ago.
The null hypothesis is:
[tex]H_{0} = 3173[/tex]
The alternate hypothesis is:
[tex]H_{A} \neq 3173[/tex]
The test statistic is:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
In which X is the sample mean, [tex]\mu[/tex] is the value tested at the null hypothesis, [tex]\sigma[/tex] is the standard deviation and n is the size of the sample.
Due to our test, we have that [tex]\mu = 3173[/tex]
Assume a population standard deviation of 1,550 customers.
This means that [tex]\sigma = 1550[/tex]
Suppose you look at a random sample of 73 stores and find an average weekly customer total of 3,391.
This means that [tex]n = 73, X = 3391[/tex]
Test statistic:
[tex]z = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}[/tex]
[tex]z = \frac{3391 - 3173}{\frac{1550}{\sqrt{73}}}[/tex]
[tex]z = 1.24[/tex]
p-value:
Since we are testing if the mean is different of a value, and the z-score is positive, the pvalue is 2 multiplied by 1 subtracted by the pvalue of z = 1.24.
z = 1.24 has a pvalue of 0.9251
2*(1 - 0.9251) = 2*0.0749 = 0.1498
0.1498 > 0.1, which means that we accept the null hypothesis, that is, that the mean weekly number of customers is equal to what it was two years ago at the 0.1 level of significance.
