Step-by-step explanation:
ALL YOU HAVE TO DO IS MULTIPLY 1/2 AND 12, WHICH GETS YOU 6! now in seconds just multiply 6 times 60 to get 360!
Answer:
6 minutes
Step-by-step explanation:
We multiply the amount of problems by the time per problem to get the equation (1/2)(12)=x where x is the time she takes to complete 12 questions. (1/2)*(12) = 6.

Given the two similar triangles below. What is the measure of x?
Answer:
x=2.4
Step-by-step explanation:
as the 2 triangles are similar,
[tex] \frac{6}{x} = \frac{5}{2} [/tex]
therefore ;
[tex]x = \frac{6 \times 2}{5} [/tex]
[tex]x = 2.4[/tex]
Answer:
The answer would be 2.4
Step-by-step explanation:
This is because 5 is the same as 2, and 7 is the same as y, and then 6 is the same as x. If you divide 5 by 2 you get 2.5 if you divide 6 by 2.5 you get 2.4

(10 A person flying a kite has released
123 ft of string. The string makes an
angle of 21 degrees with the ground. How high
is the kite ?
Answer:
The kite is about 44.1 feet high.
Step-by-step explanation
Since you are trying to find the height, you would draw a triangle to diagram which sides you need to use. The 123 ft of string would be the hypotenuse of the triangle while the 21 degrees is the theta. You are trying to find the height and from the theta that would be the opposite side so you would use sine because you are using opposite and hypotenuse.
sin21=x/123
You have sin of 21 because that is the angle measure, then opposite over hypotenuse which is x/123.
You then multiply both sides by 123 to get the variable of x alone on one side.
123sin21=x
Then just plug this into your calculator and round to the nearest tenth and you get 44.1 feet.

An air-conditioning repair technician claims to complete 67% of repairs in under an hour. A random sample of 31
repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random
sample that were completed in under an hour.
The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317. Does this
result provide convincing evidence against the technician's claim?
Yes, it is expected that 22 of the units at most will be repaired in under an hour.
Yes, the probability of seeing the sample result is so far from what is expected that the probability of it occurring by
chance alone is very unlikely.
No, there is a very small chance of seeing the sample result. It is unlikely to occur by chance alone.
No, the difference between the sample result and what is expected is not extreme enough. The probability of it
occurring by chance alone is not unlikely.
Answer:
D No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.
Step-by-step explanation:
Got it right on unit test review
The probability of it occurring by chance alone is not unlikely.
We have given that,

repairs was chosen, and 22 of those were completed in under an hour. Let p = the proportion of the random.
The sample was completed in under an hour.
What is the probability?Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one.
The probability that 71% or more of this technician's repairs were completed in under an hour is 0.317.
D No, the difference between the sample result and what is expected is not extreme enough. The probability of it occurring by chance alone is not unlikely.

A text book publisher wants to estimate the number of sentences per paragraph in a history textbook. The publisher count the number of sentences in 150 randomly selected paragraphs. The results are shown in the table. Based on the data what is the mean number of sentences per paragraph in the textbook?
A. 4
B. 5
C. 10
D. 15
Using the weighed mean, it is found that the mean number of sentences per paragraph in the textbook is given by:
B. 5
What is the weighed mean?The weighed mean is given by the sum of all elements in a data-set multiplied by it's weight, divided by the sum of the weights.
In this problem:
The sum of the values multiplied by it's weights is: 1 x 0 + 2 x 3 + 3 x 20 + 4 x 43 + 5 x 36 + 6 x 25 + 7 x 10 + 8 x 8 + 9 x 2 + 10 x 3 = 750.Considering that there are 150 books, we have the mean is:
M = 750/150 = 5.
Hence option B is correct.
