Answer:
8/35
Step-by-step explanation:
Step 1
We can't subtract two fractions with different denominators. So you need to get a common denominator. To do this, you'll multiply the denominators times each other... but the numerators have to change, too. They get multiplied by the other term's denominator.
So we multiply 3 by 5, and get 15.
Then we multiply 1 by 7, and get 7.
Next we give both terms new denominators -- 7 × 5 = 35.
So now our fractions look like this:
15
35
−
7
35
Step 2
Since our denominators match, we can subtract the numerators.
15 − 7 = 8
So the answer is:
8
35
Step 3
Last of all, we need to simplify the fraction, if possible. Can it be reduced to a simpler fraction?
To find out, we try dividing it by 2...
Nope! So now we try the next greatest prime number, 3...
Nope! So now we try the next greatest prime number, 5...
Nope! So now we try the next greatest prime number, 7...
Nope! So now we try the next greatest prime number, 11...
No good. 11 is larger than 8. So we're done reducing.
There you have it! The final answer is:
3/7
−
1/5
=
8/35
Answer:
eight over thirty- five, 8
35
Step-by-step explanation:
In order to subtract the fractions you have to do a simple mathematics step I learned in sixth grade and I still use it now, i'm in ninth grade.
So the tactic I learned in middle school was, keep change flip.
1- Take the three over the seven: 3
7
(Second part of step one)1- Then you do the same to the one and five: 1
5
2- When you subtract a fraction you cannot do it with different denominators. Therefor you have to find the same number in both of the numerator or denominator.(Across from each other)
So multiply the different denominator by each other: 3 x 5= 15
Then you do it with the one and the seven: 1 x 7= 7
Then next you give both the denominators new fractions
This is what they would look like now
15 - 7
35 35
Since the denominators match now you can subtract the numerators.
4- 15- 7= 8
So the answer for this step is now 8 over 35.
3- The last step you have to simplify the fraction. The fraction can sometimes be reduced to smaller parts. ( like 1 over 2 was simplified by 2 over 4 and so on and so on) So first you need to divide it by 2, at least try. Since you can't do that you try the next biggest prime number, 3. And you cannot do that so that moves us on to the next prime number, 5 you cannot. There are both the prime numbers, 7 and 11 but that will not work because seven can't do anything but give you a decimal and 11 is far to greater for the fraction. So you would go for the prime number in between 7 and 9, 8.

Question 1 of 10
What is the probability that a data value in a normal
distribution is between a zscore of -1.52 and a z-score of -
0.34? Round your answer to the nearest tenth of a percent.
A. 28.3%
B. 30.3%
C. 29.3%
D. 27.3%
SUBMIT
Answer:30.3
Step-by-step explanation:
30.3% is the probability that a data value in a normal distribution is between a z-score of -1.52 and a z-score of -0.34.
What is probability?Probability is a number that expresses the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
We can use a standard normal distribution table or calculator to find the probability that a data value falls between two given z-scores.
The probability of a data value being between a z-score of -1.52 and a z-score of -0.34 is equal to the area under the standard normal distribution curve between these two z-scores. We can find this area by subtracting the area to the left of -0.34 from the area to the left of -1.52:
P(-1.52 < z < -0.34) = P(z < -0.34) - P(z < -1.52)
Using a standard normal distribution table or calculator, we can find that P(z < -0.34) is approximately 0.3665 and P(z < -1.52) is approximately 0.0643. Therefore, the probability of a data value being between a z-score of -1.52 and a z-score of -0.34 is:
P(-1.52 < z < -0.34) = 0.3665 - 0.0643 = 0.3022
Rounding this answer to the nearest tenth of a percent, we get:
P(-1.52 < z < -0.34) ≈ 30.2%
Therefore, the closest answer choice is B, 30.3%.

Fay read an article that said 26% of Americans can speak more than one language. She was curious if this
figure was higher in her city, so she tested H, : p=0.26 vs. H : p > 0.26, where p represents the
proportion of people in her city that can speak more than one language.
She found that 40 of 120 people sampled could speak more than one language. The test statistic for these
results was 2 1.83.
Assuming that the necessary conditions are met, what is the approximate P-value for Fay's test?
You may round to three decimal places.
P-value
Answer:
0.0336
Step-by-step explanation:
the hint says so
According to the result of the test statistic, the approximate p-value for Fay's test is of 0.034.
How to find the p-value of a test?
It depends on the test statistic z, as follows.
For a left-tailed test, it is the area under the normal curve to the left of z, which is the p-value of z.For a right-tailed test, it is the area under the normal curve to the right of z, which is 1 subtracted by the p-value of z.For a two-tailed test, it is the area under the normal curve to the left of -z combined with the area to the right of z, hence it is 2 multiplied by 1 subtracted by the p-value of z.In this problem, we are testing if the proportion is greater than a value, hence it is a right-tailed test.
The test statistic is z = 1.83, which has a p-value of 0.966.
1 - 0.966 = 0.034.
Hence, the approximate p-value for Fay's test is of 0.034.

Two friends are to meet at the library. Each independently and randomly selects an arrival time within the same one-hour period. Each agrees to wait a maximum of fifteen minutes for the other to arrive. What is the probability that they will meet
Answer:
The probability that they will meet is 0.4375
Step-by-step explanation:
Let A and B be two friends who choose to meet the same one-hour period.Since there are 60 minutes in an hour therefore n= 60
A can wait for 15 minutes
So the probability of A to meet is given by P(A)= (15/60)= 1/4
Similarly
B can wait for 15 minutes
So the probability of B to meet is given by P(B)= (15/60)= 1/4
The probability that A cannot meet is given by 1- P(A)= 1-1/4= 3/4
Similarly
The probability that B cannot meet is given by 1- P(B)= 1-1/4= 3/4
And
The probability that both A and B cannot meet is given by = 3/4*3/4= 9/16
So the probability that both will meet = 1- 9/16= 7/16= 0.4375

How many sides does a polygon have if the sum of the interior angles is 2240
?
Answer:
Note: it seems a typo, should be 2340 instead of 2240
Sum of interior angles of a polygon:
S = 180(n - 2)We have:
S = 2340Find n:
180(n - 2) = 2340n - 2 = 2340/180n - 2 = 13n = 1515 sides
90(2n-4)=Sum of interiors
2240=90(2n-4)2240=180n-360180n=2600n=2600/180n=14.4=14what’s the value of x ?
Answer:
x=70
Step-by-step explanation:
Because these angles are on the opposite sides of each other, they have to add up to 180. This will make the equation 2x-5+45=180. Simplify this to get 2x+40=180. Subtract 40 from both sides to get 2x=140. Divide each side by 2 to isolate x. x=140/2. Simplify this to get x=70.

which expression defines function h?
Answer:
[tex]h(x) = (\frac{f}{g})(x)[/tex]
Step-by-step explanation:
Given
[tex]f(x) = 3x^3 + 9x^2 -12x[/tex]
[tex]g(x) = x - 1[/tex]
[tex]h(x) = 3x^2 + 12x[/tex]
Required
What defines h(x)
Looking at the degree of f(x), g(x) and h(x), we have:
[tex]h(x) = (\frac{f}{g})(x)[/tex]
See proof
[tex]h(x) = (\frac{f}{g})(x)[/tex]
This gives:
[tex]h(x) = \frac{f(x)}{g(x)}[/tex]
[tex]h(x) = \frac{3x^3 + 9x^2 -12x}{x - 1}[/tex]
Factorize
[tex]h(x) = \frac{(3x^2 + 12x)(x - 1)}{x - 1}\\[/tex]
[tex]h(x) = 3x^2 + 12x[/tex]

What is the degree measure of FEG?
A 20°
B 31°
C 56°
D
124°
Answer:
C) 56
Step-by-step explanation:
DEG and FEG are on a straight line forming 180 degree.
Set your formula up as
180 = (3x+31)+(2x-6)
180 = 3x +2x +31 - 6
180 - 31 + 6 = 5x
155 = 5x
155/5 = x
31 = x
Now substitute 31 in place of x
FEG = (2*31-6)
FEG = 56

4 23
5 18

Answer:
1/12
Step-by-step explanation:
To find experimental probability you have to solve the Number of times an event occurs / Total number of trials. So since the 5 only appears once and there are 12 numbers, it would be 1/12. Did this help?
The experimental probability of rolling 5 will be 0.18.
What is probability?Its fundamental concept is that someone will nearly surely occur. The proportion of positive events in comparison to the total of occurrences. Then the probability is given as,
P = (Favorable event) / (Total event)
The table is given below:
Number Total
1 12
2 16
3 21
4 23
5 18
6 10
The experimental probability of rolling a 5 is calculated as,
P = 18 / (12 + 16 + 21 + 23 + 18 + 10)
P = 18 / 100
P = 0.18
Thus, the probability is 0.18.
