The base of a 15 foot ladder is 9 feet from a building. The top of the leaning ladder reaches and makes contact with the building’s roof. On the corner of the building, a 6 foot flagpole is erected on the roof. What is the height from the base of the building to the top of the flagpole? Please show your work.
9514 1404 393
Answer:
18 feet
Step-by-step explanation:
The ladder length represents the hypotenuse of a right triangle with a base of 9 and an unknown height (h). We can find that height by using the Pythagorean theorem.
9² +h² = 15²
h² = 225 -81 = 144
h = √144 = 12
So, the ladder extends 12 feet up the side of the building. That is the height of the roof. The top of the flagpole is 6 feet above that, so the top of the flagpole is ...
12 ft + 6 ft = 18 ft
above the ground.
The height to the top of the flagpole is 18 feet.

The enrollment at a university increased from 16,000 students to 20,000 students over a period of 5
years. What is the percent increase in enrollment?
difference
net/
Answer:
25%
Step-by-step explanation:
Initial no of students = 16,000
Final no of students = 20,000
We need to find the percent increase in enrollment.
The increase in no of students = 20,000 - 16,000
= 4000
Percentage = (increase/initial no of students) × 100
[tex]\%=\dfrac{4000}{16000}\times 100\\\\=25\%[/tex]
Hence, the percent increase is 25%.

then your baby sister took 3 10-3=2
There is 2 left because you subtract 5 from 10 and that leave you with 5 and then you subtract three and get 2 and that’s your answer 2
The meaning of significance. Asked to explain the meaning of "statistically significant at the α=0.05 level," a student says: "This means that the probability that the null hypothesis is true is less than 0.05." Is this explanation correct? Why or why not?
Answer:
This explanation is not correct
Explanation:
Significance level is the probability that the null hypothesis rejected is in fact true. If we say there is a significance level of 0.10 or 10%(α=0.10 level) then there is a 10% chance of incorrectly rejecting the null hypothesis when there is actually no difference.
If we wish to reach a conclusion on rejection or acceptance of the null hypothesis, we could use the p value(the probability that observed results or more extremee results are true given null hypothesis)which we compare with the significance level to conclude. If the significance level is 0.10 and p value is 0.07(since p value is less than significance level) , we reject the null hypothesis and vice versa.
The significant level, α = 0.05 level specifies a probability of the correctness of the null hypothesis.
The student is correct in the statement "This means that the probability that the null hypothesis is true is less than 0.05"
Reasons:
The significant level specifies the the likelihood of rejecting a true null
hypothesis, such that a 5% significance level indicates that the risk of
drawing a conclusion that there is a difference in a sample, when the
samples are similar is 5%, and therefore, the probability that null
hypothesis is true is 5% or 0.05.
The level of significance is a specification that indicates the amount of
evidence required within a sample to allow the rejection of the null
hypothesis, and reach a conclusion that the observed effect is statistical
significant at the α = 0.05 level.
Therefore;
The statement by the student that "This means that the probability that the null hypothesis is true is less than 0.05" is correct.

There are 3 times as many dogs as cats.
If the total number of dogs and cats is 16, how many dogs are there?
Answer:
there are 12 dogs.
Step-by-step explanation:
d= dogs now plug in the 4 into your equation.
c= cats d=3(4)
d+c=16 d=12
3c+c=16
4c=16 SO THEREFORE THERE ARE 12 DOGS :)

As of the moment I am writing this question, the population of the United States is 326,891,705 people. You are building an app that targets the US population and expect to get 1/10 of 1% of the population using your app in the first 4 months. The estimated data you need to store per user averages 10 GB. What is the minimum storage you must plan to have in place for app to serve the users in the first 4 months
Answer:
3.3 PB
Step-by-step explanation:
It is given tat the population of the U.S = 326,891,705 people.
Population expected to use the app in first 4 months = 1/10 of 1%
Storage capacity of an user is = 10 GB
Therefore,
[tex]$\frac{1}{10} \text{ of}\ 1$[/tex] % = 0.1%
= 0.001
The user content = 0.001 x 326,891,705
= 326891.705 users
10 GB storage per user.
Therefore,
Size = 326891.705 x 10
= 3268917.05 GB
= 3.26 PB
Hence size of the minimum storage would be 3.3 PB.
