Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
Tan(65) = Opp / 10
10* Tan(65) = Opp
21.445 = Opp
so the height of the tree is approx 21.4 feet ( to the nearest 10th )

Data from a representative sample were used to estimate that 31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money. You decide to conduct a survey to estimate this proportion for the current year. What is the required sample size if you want to estimate this proportion with a margin of error of 0.05
Answer:
The required sample size is 329.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
31% of all computer users in a recent year had tried to get on a Wi-Fi network that was not their own in order to save money.
This means that [tex]\pi = 0.31[/tex]
Confidence level is not given, so we assume 95%.
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
What is the required sample size if you want to estimate this proportion with a margin of error of 0.05?
We need a sample size of n. n is found when M = 0.05. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.05 = 1.96\sqrt{\frac{0.31*0.69}{n}}[/tex]
[tex]0.05\sqrt{n} = 1.96\sqrt{0.31*0.69}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.31*0.69}}{0.05}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.31*0.69}}{0.05})^2[/tex]
[tex]n = 328.6[/tex]
Rounding up
The required sample size is 329.

Sophie can type 128 words in three minutes how many minutes will it take her to type 576 words?
Answer:
13 minutes and 30 seconds
Step-by-step explanation:
Okay so first you would divide 128 by 576. But since it takes her 3 minutes just to type 128 words you have to multiply 4.5 times 3. It will take her 13.5 minutes to type 576 words or 13 minutes and 30 seconds.
What is the population in 2020 of a place that has a population of 4 million people in 2011 and is growing at a rate of 1.3%?
Answer:
370 million
Step-by-step explanation:
In the 10 years from 2000 to 2010, the population was multiplied by the factor ...
100% + 9.6% = 109.6% = 1.096
In the next 20 years from 2010 to 2030, the population will be multiplied by that factor twice, if it grows at the same rate:
2030 population = (308 million)·(1.096²) ≈ 370 million
Reasoning : Why is the numerator greater than
the denominator in a fraction that is equivalent
to a percent greater than 100?
Answer:
See the explanation
Step-by-step explanation:
When the numerator is less than the denominator, the result is always less than 1, that is 0. something and this will give a percentage less than 100, but when the numerator is greater than the denominator, th result is greater than 1, and any figure greater than 1 gives a percentage that is greater than 100
example
Numerator >Denominator
=4/2*100
=2*100
=200%
Numerator <Denominator
=2/4*100
=0/5*100
=50%
How many days is 1,000 hours?
Answer:
41.6666667 or 41 2/3 days
Step-by-step explanation:
There are 24 hours in a day. So you need to divide the hours by 24.
1000/24 is 41 and 2/3 days
Answer:
41.666667
Explanation:
Divide by 24 because 1 day is 24 hours
1000 / 24 = 41.666667

Two sides of a right triangle are 8 and 12. Find the missing side of 8 and 12 are a leg and a hypotenuse.
Answer:
8.94 if no rounding is necessary.
Step-by-step explanation:
Pythagorean Theorem. What we know is only one leg and the hypotenuse, sooo...
8² + b² = 12²
64 + b² = 144
Subtract 64 from both sides...
64 - 64 + b² = 144 - 64
b² = 80
[tex]\sqrt{80}[/tex] = 8.94 if you're not rounding.
What is the common difference between successive terms in the sequence?
2, 8, 14, 20, 26, ...
-6
-4
ООО

о в
Let be a1 = 8 and a2 = 8 [ From question ]
We have to find out common differences which denoted by letter d .
d = a2 - a1 [ Formula ]
= 8 - 2
= 6
Thus,the common difference between successive terms in the sequence is 6 .
Answer:
6.
Step-by-step explanation:
We have to find out common differences which denoted by letter d .
d = a2 - a1 [ Formula ]
= 8 - 2
= 6
Also,
2+6=8 +6=14 +6=20 +6=26
So, It's Added Up By 6.
What is the surface area of this triangular pyramid?
___square inches
Answer:
Surface area = 10.7 in.²
Step-by-step explanation:
Surface Area of triangular pyramid = BA + P*L
Base Area (BA) = ½*nh
b = 2 in.
h = 1.7 in.
BA = ½*2*1.7 = 1.7 in.²
Perimeter (P) = 2 + 2 + 2 = 6 in.
Slant height (L) = 3 in.
Plug in the values
Surface Area = 1.7 + ½*6*3
Surface area = 10.7 in.²
2/10 convert to a decimal
Answer:
0.2 is the answer
-your welcome and have a great day!!
What is the area?
30
32 in
Step-by-step explanation:
Here's your solution
=> Base = 32 In
=> Height = 30 in
=> Area of traingle = 1/2*base *height
=> putting the value of base and height in formula
=> Area = 1/2*30*32
=> Area = 480 in sq
