Apple launches an ad campaign for iPhone 12. Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign. How many social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2% (ME=0.02)?
Answer:
social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%
Sample size 'n' = 625
Step-by-step explanation:
Step(i):-
Given data Apple launches an ad campaign for iPhone 12
Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign
probability of positive reactions p = 1/2
Probability of negative reactions q = 1-p = 1/2
we know that [tex]\sqrt{p(1-p}\leq \frac{1}{2}[/tex]
Step(ii):-
Given margin of error = 2 % =0.02
The margin of error is determined by
[tex]M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }[/tex]
[tex]0.02 = \frac{\frac{1}{2} }{\sqrt{n} }[/tex]
[tex]\sqrt{n} =\frac{1}{2 X0.02}[/tex]
√n = 25
squaring on both sides, we get
n = 625
A cylindrical garbage can has the dimensions shown.
A cylinder has a diameter labeled twelve inches and height labeled fifteen inches.
What is the area of the horizontal cross section of the cylinder? Use 3.14 for π.
Answer:
113.04 square inchesStep-by-step explanation:
Horizontal cross-section of a cylinder is a circle with same dimension as its base
Given diameter
12 inchesArea formula
A = πr² = πd²/4So the area of cross section is:
A = 3.14*12²/4 = 113.04 square inchesThe ratio of the side lengths of a triangle is 2:3:4. The shortest side is 15 inches. What is the perimeter? Explain. Pleas show your work. I will give brainiest to the best and first answer
Ratio of the sides of the triangles,
2 : 3 : 4
Let's consider each side to be
2x,3x and 4x
Therefore the perimeter of the triangle is,
2x + 3x + 4 x = 9x
The shortest side is 15 inches.
We know that the smallest value in the above ratio is 2
Therefore,
2x = 15 inches
x = 7.5 inches
☞Perimeter of the triangle
= 9x
= 9 * 7.5 inches
= 67.5 inches

which value of p is the solution of 5p-1=2p+20
Answer:
p=7
Step-by-step explanation:
5p-1=2p+20 first add 1 to both sides to get 5p=2p+21, then subtract 2p from both sides to get 3p=21, then divide by three to get p=7
Since the 1800s, fossil fuels have been used to meet the energy needs of many human activities.
Select TWO statements that describe what the scientists will observe in the ecosystem after fossil fuels have been extracted and burned.
Group of answer choices
There is more available space for carbon to become fossil fuels.
There is less carbon in storage.
There will be less carbon in the water.
There is more carbon in the atmosphere.
There will be more carbon respired by organisms.
There will be less carbon released through decomposition.
Answer:
Below.
Step-by-step explanation:
There will be more carbon in the atmosphere.
There is less carbon in storage.
Answer:
1. There is more carbon in the atmosphere.
2. There is more available space for carbon to become fossil fuels.
Step-by-step explanation:
When plants and animals die, their bodies, wood and leaves decays bringing the carbon into the ground. Some is buried and will become fossil fuels in millions and millions of years. Each year, five and a half billion tons of carbon is released by burning fossil fuels. Of this massive amount, 3.3 billion tons stays in the atmosphere. When fossil fuels are burned, they release nitrogen oxides into the atmosphere, which contribute to the formation of smog and acid rain.

Step-by-step explanation:
Paul, Colin and Brian are waiters.
One night the restaurant earns tips totalling £78.40.
They share the tips in the ratio 2:1:5.
How much more does Brian get over Colin?
Let 2x = Paul
Let x = Colin
Let 5x = Brian
2x + x + 5x = 78.40
8x = 78.40
x = 78.40 ÷ 8
x = 9.8
Brian gets 5(9.8) which is 49.
Colin gets 9.8.
Brain over Colin means 49/9.8 = 5.
Brain gets £5 more than Colin in terms of a tip.

Nancy Boone’s new automobile had an MSRP of $27,853.00. The dealer prep charge was $278.50 and the title fee was $25.00. Options totaled $2,375.50. Find the sales tax rate, to nearest hundredth percent, if the total cost was $32,591.22 and the sales tax applied to everything but the title fee.
Answer:
The sales tax included in the sale of the car is 15.76%.
Step-by-step explanation:
Given that the MSRP of the car bought by Nancy Boone is $ 27,853, and the total cost of the car was $ 32,591.22, including sales tax, plus a dealer prep charge of $ 278.50 and a title fee of $ 25, to find out the percentage of sales tax ( which does not include the title fee) it is necessary to perform the following calculation:
32,591.22 - 25 = 32,566.22
27,853 + 278.5 = 100
32,566.22 = X
28,131.5 = 100
32,566.22 = X
(32,566.22 x 100) / 28,131.5 = X
3,256,622 / 28,131.5 = X
115.76 = X
115.76 - 100 = 15.76
Thus, the sales tax included in the sale of the car is 15.76%.
