This question is incomplete, the complete question is;
In two shipments of fruit, A and B, the proportions of fruit that are apples are [tex]P^"_{A}[/tex] and [tex]P^"_{B}[/tex] , respectively. Suppose that independent random samples of 50 fruit from A and 100 fruit from B. Let [tex]P^"_{A}[/tex] be the sample proportion of apples from shipment A and [tex]P^"_{B}[/tex] be the sample proportion of apples from shipment B. What is the mean of the sampling distribution of [tex]P^"_{A}[/tex] - [tex]P^"_{B}[/tex] ?
Answer:
the mean of the sampling distribution is [tex]P^"_{A}[/tex] - [tex]P^"_{B}[/tex]
Step-by-step explanation:
Given the data in the question;
let [tex]X_{A}[/tex] be number of apples from the shipment A
and [tex]X_{B}[/tex] be number of apples from shipment B
[tex]P^"_{A}[/tex] = [tex]X_{A}[/tex] / [tex]n_{A}[/tex] = [tex]X_{A}[/tex] / 50 { x ¬ Bin(np )
{ [tex]X_{A}[/tex] = 50[tex]P^"_{A}[/tex] )
[tex]P^"_{B}[/tex] = [tex]X_{B}[/tex] / [tex]n_{B}[/tex] = [tex]X_{B}[/tex] / 100
( [tex]X_{B}[/tex] = 100[tex]P^"_{B}[/tex] )
E( [tex]P^"_{A}[/tex] - [tex]P^"_{B}[/tex] ) = E( [tex]X_{A}[/tex] / [tex]n_{A}[/tex] - [tex]X_{B}[/tex] / [tex]n_{B}[/tex] )
= E( [tex]X_{A}[/tex] / 50 - [tex]X_{B}[/tex] / 100 )
= E([tex]X_{A}[/tex]) / 50 - E([tex]X_{B}[/tex]) / 100
= 50[tex]P^"_{A}[/tex] / 50 - 100[tex]P^"_{B}[/tex] / 100
= [tex]P^"_{A}[/tex] - [tex]P^"_{B}[/tex] { E(X) = np ]
Therefore, the mean of the sampling distribution is [tex]P^"_{A}[/tex] - [tex]P^"_{B}[/tex]

15 + w = 3w - 11
Solve for W
Answer:
w=13
Step-by-step explanation:
15+w=3w-11
+11 +11
26+w=3w
-w -w
26=2w
26/2=2w/2
13=w
Answer:
w =13
Step-by-step explanation:
15+w=3w−11
Collect like terms
15+11=3w−w
Simplify
26=2w
Divide both sides of the equationy 2
26/2=2w/2
Simplify
13=w
switch sides
w=13
What would the equation be for this then

Samples of laboratory glass are in small, light packaging or heavy, large packaging. Suppose that 2% and 1% of the sample shipped in small and large packages, respectively, break during transit. If 58% of the samples are shipped in large packages and 42% are shipped in small packages, what proportion of samples break during shipment
Answer:
Total proportion of samples that break during shipment [tex]1.42[/tex] %
Step-by-step explanation:
Let the total number of glasses shipped is equal to [tex]100[/tex]
[tex]58[/tex] % of the glasses are shipped in large packets [tex]\frac{58}{100}*100 = 58[/tex]
[tex]42[/tex] % of the glasses are shipped in small packets [tex]\frac{42}{100}*100 = 42[/tex]
Number of broken glasses in small package [tex]= \frac{2}{100} * 42 = 0.84[/tex]
Number of broken glasses in large package [tex]= \frac{1}{100} * 58 = 0.58[/tex]
Total proportion of samples that break during shipment
[tex]\frac{0.84 + 0.58}{100} *100 = 1.42[/tex] %

Find an equation of the tangent line to the curve at the given point. y = 6x - x^3, (1,5)
Step-by-step explanation:
Recall that the first derivative of an equation gives us the SLOPE for the tangent line.
So first, we should find the first derivative.
[tex]\frac{dy}{dx} = 6 - 3x^2[/tex]
With the first derivative, we can solve for the SLOPE of the tangent line at (1,5).
Using x = 1.
[tex]slope = 6 - 3(1)^2[/tex]
A tangent line is a line. And has the form [tex]y = mx +b[/tex]
Where m is the SLOPE of the line. and b is the y-intercept.
To get to this equation, let's use the point-slope technique.
[tex]y-y_1 = m(x-x_1)[/tex]
[tex]y - 5 = m(x-1)[/tex]
Solve for slope, substitute it into this equation for m and solve. That is the equation of the tangent line at the point (1,5).

What is unit conversion?It is the conversion of one unit to another unit with its standard conversion.
1 minute = 60 seconds
1 hour = 60 minutes
1 km = 1000 m
1 m = 100 cm
We have,
Shed dimensions in the blueprint:
Wide = 7 inches
Length = 3 inches
The scale factor:
34 inch = 3 feet
This means,
Multiply 7/34 on both sides of (1).
7/34 x 34 inch = 7/34 x 3 feet
7 inch = 21/34 feet
7 inch = 0.62 feet _____(A)
Multiply 3/34 on both sides of (1).
3/34 x 34 inches = 3/34 x 3 feet
3 inches = 0.26 feet ______(B)
From (A) and (B) we get,
Wide = 0.62 feet
Length = 0.26 feet
The actual dimension of the shed.
Length = 0.26 feet
Wide = 0.62 feet
Thus,
The dimension of the actual shed.
Length = 0.26 feet
Wide = 0.62 feet

how can I do this, can you explain me
Answer:
Step-by-step explanation:
Start with h(t) = -16t^2 + initial height, which here is h(t) = -16t^2 + 1296. Set this = to zero, which corresponds to the object hitting the ground (h = 0):
0 = -16t^2 + 1296. Dividing all terms by -16, we get t^2 = 81, whose positive square root is 9. It takes 9 seconds for the object to hit the ground.

Tina invests $3,700 into an account with a 4.4% interest that is compounded quarterly. How much money will she have in
this account if she keeps it for 8 years?
Round your answer to the nearest cent.
DO NOT round until you have calculated the final answer.
Answer:
5250.96
Step-by-step explanation:
The 4.4% interest rate compounded quarterly means that you get 4.4%/4 four times a year. Over 8 years, that is 32 times. Since we use decimals, not percentages, we get
[tex]3700(1+0.044/4)^(4*8)=5250.96[/tex]

Katie wants to know how much she needs to deposit into a two year CD account in order to earn $100 in simple interest. The account currently has a 1.5% interest rate. Round to the nearest cent . SHOW ALL WORK FOR ANY CREDIT!!
Answer:
To obtain $ 100 in simple interest with a rate of 1.5%, Katie must deposit $ 6,666.66.
Step-by-step explanation:
Given that Katie wants to know how much she needs to deposit into a two year CD account in order to earn $ 100 in simple interest, knowing that the account currently has a 1.5% interest rate, the following calculation must be performed:
X x 0.015 = 100
X = 100 / 0.015
X = 6,666.66
6,666.66 x 1.015 = 6,766.66
Thus, to obtain $ 100 in simple interest with a rate of 1.5%, Katie must deposit $ 6,666.66.
