The pooled sample proportion requires two samples combined to estimate the single p instead of estimating p1 and p2 separately. Therefore, it's true.
What is a pooled sample?It should be noted that the pooled sample of a proportion is the weighted average of the proportion from the two samples.
In this case, the combined pool sample is called the poooled sample proportion and it's used in expression of the standard error.
In conclusion, the correct option is true.

You text your friend for 15 minutes on friday night and for 25 minutes on saturday night. what is the percent of increase? (round to nearest whole percent)
Answer:
66%
Step-by-step explanation:
This doesn't really require any equations, it's just brain work.
15 can be easily divided into 3 parts, each part consisting of 5 units. Here, it will be 5 minutes, then, if it's 5 minutes for each 33%(this number is rounded), then, that means that for 10 minutes, it will be 66%. You can understand this because the amount of increase in minutes is 10 minutes, and if each 5 minutes = 33% of increase, then 33+33=66, so hence, our answer is 66%.

Haven baskets manufacturers 83,575 woven baskets a year. determine the minimum sales price Haven baskets must sell each basket for to break even, if the total annual fixed costs are $817,363.50 and the variable cost per basket is $12.17.
$21.95
$24.50
$29.65
$31.25
Answer:
Step-by-step explanation:
Givens
Number of baskets sold = 83575
sale price of each = x
Fixed Cost of producing these baskets = 817363.50
Variable cost whis is part of the production of each basket = 12.17
Break Even means the costs = income.
Equation
83575*x = 12.17*83575 + 817363.50 Combine the multiplied facts
Solution
83575x = 1017107.75 + 817363.50 Combine addition on right
83575x = 1834471.25 Divide by 83575
x = 1834471.25/83575
Answer: x = 21.95
In Texas, the average number of tornadoes in May was about 154% of the average number of tornadoes in April. Write and solve a proportion to find the average number of tornadoes that occurred in April.
The table of the average number of tornadoes is an illustration of proportions
The average number of tornadoes in April is 28
How to determine the average number of tornadoes in April?From the table, we have:
Average number of tornadoes in May in Texas = 43
From the question, we have:
May = 154% * April
This gives
43 = 154% * April
Express as decimal
43 = 1.54 * April
Divide both sides by 1.54
April = 27.9
Approximate
April = 28
Hence, the average number of tornadoes in April is 28

The expression equivalent to 23−14x+12x−16 is 7 - 2x
How to find equivalent expressions?Here we simply take our expression to simplify it.
We start with:
23−14x+12x−16
First, we combine all the terms having x and combine other constant values.
(23 - 16) + (-14x + 12x)
Now we solve the two parts of the above expression we will get,
7 + (- 2x)
Simplifying we get,
7 - 2x
Therefore the equivalent expression is 7 - 2x

sketch the region enclosed by the lines x=0 x=6 y=2 and y=6 find the area of the region
Answer:
24 units²
Step-by-step explanation:
Given:
Region enclosed by the line x = 0, x = 6, y = 2 and y = 6.To find:
SketchAreaThe area enclosed by these lines can be expressed as:
[tex]\displaystyle \large{\int_0^6 \int_2^6 dy dx }[/tex]
For:
[tex]\displaystyle \large{\int_2^6 dy}[/tex]
Recall:
[tex]\displaystyle \large{\int_a^b dy = [y]_b^a = a-b}[/tex]
Therefore:
[tex]\displaystyle \large{\int_2^6 dy = [y]_2^6 = 6-2 = 4}[/tex]
Now we we have:
[tex]\displaystyle \large{\int_0^6 4dx}[/tex]
Recall:
[tex]\displaystyle \large{\int_a^bk dx = [kx]_a^b = kb-ka}[/tex]
for k = constant
Therefore:
[tex]\displaystyle \large{\int_0^6 4 dx = [4x]_0^6 = 4(6)-4(0) = 24}[/tex]
Hence, the area of region is 24 units²

A cylinder has a volume of 825.192 cubic centimeters. The diameter of the cylinder is 12 cm. What is the height of the cylinder?
Answer:
Step-by-step explanation:
diameter = 12 cm
r = 12 ÷2 = 6cm
Volume of cylinder
[tex]\boxed{Volume=\pi r^{2}h}[/tex]
πr²h = 825.192 cubic cm
3.14 * 6 * 6 * h = 825.192
[tex]h =\dfrac{825.192}{3.14*6*6}[/tex]
h = 7.3 cm
Answer:
Height of cylinder is 7.3 cm
Step-by-step explanation:
Given :-
Diameter of cylinder is 12m , so radius would be 6mVolume of cylindrical is 825.192 cm³To find :-
Height of cylinderSolution:-
Volume of Cylinder = πr²h
825.192 cm³ = 3.14 × 6 × 6 × h

What is the value of x? Your answer may be exact or rounded to the
nearest tenth.
The value of x in the given figure is 91 degrees.
What is Triangle?A triangle is a three-sided polygon that consists of three edges and three vertices.
We need to find the value of x in the given figure.
To find x, firstly we need to find the unknown interior angle.
By Angle sum property the sum of three angles of a triangle is 180 degrees.
a+54+37=180
a+91=180
Now subtract 91 from both sides
a=180-91
a=89 degrees.
Now let us find the value of x which is adjacent to 89 degrees.
The sum should be 180 degrees
a+x=180
89+x=180
Subtract 89 from both sides
x=91 degrees
Hence, the value of x in the given figure is 91 degrees.

Answer:

Step-by-step explanation:
V=l*w*h V=1/2*b*h*l
V of the rectangular block: 15*5*8 = 600
V of the triangular prism--it's easiest to solve half of it, then just multiply that answer by 2: 1/2*5*7*9 = 157.5
When you double it, it cancels out the 1/2

if ey/n + k = t, what is y in terms of e, n, k, and t?
1) y= tn+k/e
2) y= tn-k/e
3) y= n(t+k)/e
4) y= n(t-k)/e
Answer:
option 4
Step-by-step explanation:
To write in terms of y
Step 1: subtract k from both sides
[tex]\sf \dfrac{ey}{n} + k - k = t -k\\\\\\\dfrac{ey}{n}=t-k[/tex]
Step 2: Multiply the entire equation by n
[tex]\sf n*\dfrac{ey}{n}=n*(t-k)\\\\\\ey=n(t-k)[/tex]
Step 3: Divide the entire equation by 'e'
[tex]\sf \dfrac{ey}{e}=\dfrac{n(t-k)}{e}\\\\\\\boxed{y =\dfrac{n(t-k)}{e}}[/tex]
