A file that is 242 megabytes is being downloaded. If the download is 13.2% complete, how many megabytes have been downloaded? Round your answer to
the nearest tenth.
Answer:
31.9 mb
Step-by-step explanation:
242 is the total amount of megabytes in this situation so times 242 by .132 is equal to 13.2% of the total amount of megabytes
What is the value of x?
Answer:
The value of x=12
Step-by-step explanation:
because the whole thing is 90 and the other angles are equal to 78 if you add them together. So you would subtract 90-78 which equals 12.

There are 90 monkeys in a zoo.
72 like to eat bananas
31 like to eat apples
24 like to eat apples AND bananas
How many monkeys (out of the 90), like to eat only apples or only bananas, but not both?
Answer:
66
Step-by-step explanation:
Well funny enough I think this is a twisted quiz coz directly the last statement says;24 like to eat both apples and bananas,so those that don't like both but like either of them is simply 90-24=66.

"Fifty-seven more than two times j"
Answer:
2j+57
Step-by-step explanation:
Two times a umber j is expressed as 2j
if Fifty-seven is more than two times j", this means we will have to add 57 to 2j as shown;
f(j) = 2j + 57
Hence the statement written as a function is expressed as 2j+57
In the drawing below, line h is parallel to line k.
What is the value of y?
A. 135
B. 15
C. 35
D. 145
Answer:
D. 145
Step-by-step explanation:
the lines are parallel, so you can set the two expressions equal to each other:
2x + 5 = 3x - 10
x - 10 = 5
x = 15
then plug in x to the angle next to y: 2(15) + 5 = 35°
180 - 35 = 145°

what is the answer to this simplify
2(3 + 5y)
Answer:
6 + 10y
Step-by-step explanation:
Hi,
To begin, you need to distribute the 2 to 3 and 5y (same thing as multiplying it).
2(3 + 5y)
6 + 10y
(Multiply the 2 by 3 and then the 2 by 5y)
Since 6 doesn't have a variable and 10y does, you can't combine them and, therefore, 6 + 10y is your answer.
I hope this helps :)

Area = 47.5 yd²
What are the solution(s) to the quadratic equation 40 - x2 = 0?
O x = +2/10
O x = +4/10
O x = +2/5
x = +4V5
Answer:
±2sqrt(10)
Step-by-step explanation:
40 - x^2 = 0
Add x^2 to each side
40 -x^2 + x^2 = x^2
40 =x^2
Take the square root of each side
±sqrt(40) =sqrt(x^2)
±sqrt(4)sqrt(10) =x
±2sqrt(10) =x

Much concern has been expressed regarding the practice of using nitrates as meat preservatives. In one study involving possible effects of these chemicals, bacteria cultures were grown in a medium containing nitrates. The rate of up take of radio-labeled amino acid (in dpm, disintegrations per minute) was then determined for each culture, yielding the following observations:
7251 6871 9632 6866 9094 5849 8957 7978 7064 7494 7883 8178 7523 8724 7468
Suppose that it is know that the mean rate of uptake for cultures without nitrates is 8000. Do the data suggest that the addition of nitrates results in a decrease in the mean rate of uptake? Test the appropriate hypotheses using a significance level of .10.
Please use all 9 steps to answer this question with exact numbers in the question. Thank you!!
1. Describe the population characteristic about which hypotheses are to be tested.
2. State the null hypothesis H0.
3. State the alternative hypothesis Ha.
4. Choose the significance level, a, for the test. Note: Many times a will be specified in the problem, so just state it here. If it is not given, you are free to choose an appropriate significance level like a = .05
5. Check to make sure that any conditions/assumptions required for the test are reasonable. Note: Even if you believe that the assumptions have not been met, make a note of that and then say, "but we will proceed with the test anyway".
6. Clearly display the test statistic to be used and calculate the observed value of the test statistic.
7. Determine the P-value associated with the observed value of the test statistic.
8. State the conclusion (reject H0 or fail to reject H0) with reference to the level of significance.
9. State a final conclusion in the context of the problem.
Answer:
1) μ = 8000
2) H0: μ ≥8000
3) Ha: μ < 8000
4) α= 0.10
5) If the sample size is at least 15 a student's t test can be used.And we assume that the variances of the two independent groups are almost equal.
6) t= x`- μ/ s.d/ √n = -0.816
7) The P- value = 0.214083.
8) The critical region is [-∞, -1.345]
9) Fail to Reject the Null Hypothesis
Step-by-step explanation:
1) The population characteristic is the population mean =μ = 8000
2) The claim is that the addition of nitrates results in a decrease in the mean rate of uptake i.e μ < 8000
The null hypothesis is that μ ≥ 8000
2) Null hypothesis: H0: μ ≥8000
3) Alternative hypothesis: Ha: μ < 8000
4) The significance level alpha = α= 0.10
5) If the sample size is at least 15 a student's t test can be used.And we assume that the variances of the two independent groups are almost equal.
Calculating mean and standard deviation using a calculator
Sample Size, n: 15
Mean= ∑ x/n = x`=: 7788.8
∑ x/n= 116832/15
St Dev, s.d(n-1) : 1002.4307
6) Test Statistic: student's t Test with d.f = n-1 = 14
t= x`- μ/ s.d/ √n
t= 7788.8-8000/1002.4307/√15
t= -0.816
7) The P- value for the observed t value is 0.214083.
The result is not significant at p < 0.10. H0 is accepted.
8) The Critical value for one sided t test at α =0.1 with 14 d.f is less than t= -1.3406
Hence the critical region is [-∞, -1.345]
Since the calculated t -0.816 value does not fall in the critical region [-∞, -1.345] there is not sufficient evidence to reject H0
9) Fail to Reject the Null Hypothesis
Sample does not provide enough evidence to support the null hypothesis and conclude that the data suggest that the addition of nitrates do not result in a decrease in the mean rate of uptake. The claim is rejected.

Lucas and Tayvan can paint a house in 1 hour working together. If Tayvan works alone, he can paint the house in 1.5 hours. How long would it take Lucas to complete the job on his own?
Answer:
1 hour
Step-by-step explanation:
no explanation its common sense lol
Lucas can complete the work on his own in 3 hours if Lucas and Tayvan can paint a house in 1 hour working together. If Trayvon works alone, he can paint the house in 1.5 hours.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Lucas and Tayvan can paint a house in 1 hour working together. If Trayvon works alone, he can paint the house in 1.5 hours.
Let x be the time that took by Lucas to complete the job on his own
From the question:
1/x + 1/1.5 = 1/1
Because Trayvon can paint the house in 1.5 hours
After solving the above equation:
1/x = 1 - 1/1.5
1/x = (1.5-1)/1.5
1/x = 0.5/1.5
x = 1.5/0.5
x = 3 hours
Thus, Lucas can complete the work on his own in 3 hours if Lucas and Tayvan can paint a house in 1 hour working together. If Trayvon works alone, he can paint the house in 1.5 hours.
