Answer:
D. 24%Step-by-step explanation:
Number of 4 generated is 7 and number of 7 generated is 5.
Total of 7 + 5 = 12 outcomes out of 50:
P(4 or 7) = 12/50 = 24/100 = 24%The experimental probability of the computer generating a 4 or a 7 is D. 24%.
What is experimental probability?Experimental probability calculates the probability of some event from the results of experiments.
For an event E, we get the experimental probability of that event
[tex]P_e(E) = \dfrac{\text{Number of times E occurred}}{\text{Number of times experiments was done}}[/tex]
where P_e(E) is denoting the experimental probability of occurrence of E.
A computer generates 50 integers from 1 to 8 at random. The results are recorded in this table.
Outcome 1 2 3 4 5 6 7 8
Number of times outcome occurred
5 8 9 7 4 6 5 6
The Total of 7 + 5 = 12 outcomes out of 50:
The experimental probability of the computer generating a 4 or a 7
P(4 or 7) = 12/50
= 24/100
= 24%

A Tom bought these 3 t shirts at the sale price of $ 14. 50. How much money did he save compared to the original total of the t shirts B what percentage of the total price did Tom save
Answer:
$2.47
14.6%
Step-by-step explanation:
Total of the original prices:
$3.99 + $6.99 + $5.99 = $16.97
He paid $14.50 for the 3 shirts.
$16.97 - $14.50 = $2.47
He saved $2.47.
The percent he saved is
2.47/16.97 × 100% = 14.6%

Answer:
The ratio is 1/2 : 2.
The value of the ratio is 1/4.
The amount of salt in the recipe is 1/4 the amount of flour.
Step-by-step explanation:
The ratio of the salt to flour is the amount of salt and the amount of flour
1/2 cup salt and 2 cups flour would be 1/2 : 2 The value of a ratio is the ratio simplified (if we make the 1/2 a whole number we would multiply both sides of the ratio by 2 to get 1:4 or 1/4).
1/2 cup is a fourth of 2 cups
I'm not super familiar with ratio values but I'm pretty sure this is correct.

Answer:
The mode if 5, because 5 occurs 8 times, which is more than any other numbers occurring more than once. The median is 6, and this is because when you line up the numbers in order and cross them off to find the middle number, it is 6. I rounded to the mean to about 6.4. I got this by adding all of the numbers up, or by doing 12 + 40 +18 +7, etc, and got the total of 165. Because there is a total of 26 data points, I divided those numbers and got 6.3461, which ends up rounding to 6.4.

If 1 inch represents 10 miles on a map, then how many inches will represent
120 miles?
Answer:
12 inches
Step-by-step explanation:
120/10 * 1 = 12 inches
Answer:
12 inches
Step-by-step explanation:
This question is asking for us to find the amount of inches that is represented to the amount of miles given (120 miles). In order to do this, let's divide the amount of miles that we need to find out for inches, over what information we already have. By dividing 120 over 10, that will give us the amount of inches that 120 miles represents. So:
120 miles / 10 miles = 12 inches.
This is true, because fractions are basically like division. As our example shows, 120 ÷ 10 = 12, which is true.
I hope that this helps.

Two kindergarteners participated in a fundraiser event "Walk
Backwards for Hunger" last weekend. John walked 2/3 of a mile and Mary
walked 3/4 of a mile. Together, they raised $93.50. How much money, each, did
John and Mary raise? Just so you know, the amount raised is proportional to
distance walked
Answer:
John = $44 Mary = $49.50
Step-by-step explanation:
2/3 + 3/4 = 17/12
17/12x = 93.5
17/12x x 12 = 93.5 x 12
17x = 1122
17x/17 = 1122/17
x = 66
2/3x = 66 x 2/3
2/3x = 44
3/4x = 66 x 3/4
3/4x = 49.5
44 + 49.5 = 93.5
John earned $44 while Mary earned $49.5.

MF lent $5,000 to Amit on January 01, 2020. (For simplicity, we assume there is no interest.) At the time of loan issuance, MF estimated that $500 of loans receivable would probably be uncollectible, based on their knowledge of historical credit losses.
From the information given regarding the loan, the amount that will be expected is $4500.
What is an uncollectible loan?It should be noted that an uncollectible loan or account uncollectible are the receivables or loans that have no chance of being paid.
From the question, the amount lent is $5000 and the uncollectible is $500. Therefore, the amount that will be expected to be collected will be:
= $5000 - $500.
= $4500
In conclusion, $4500 will be expected.

There are 1213 registered voters in Paul's village. During the last election 887 people actually voted. Which of the following is approximately the ratio of the number of the people who voted to the total number of registered voters in the village?
Answer:
3 : 4
Step-by-step explanation:
Given:
1213 = total number of registered voters887 = people who votedratio of people who voted to total number of registered voters:
To find the approx ratio, round both numbers to the nearest hundred:
887 ≈ 9001213 ≈ 1200Therefore, 887 : 1213 ≈ 900 : 1200
The greatest common factor of 900 and 1200 is 300,
so we can reduce the ratio further by dividing both sides by 300:
⇒ 900 : 1200 = 3 : 4

What is the amplitude of the function shown in the graph?
Enter your answer in the box.
Answer:
1.5
Step-by-step explanation:
Amplitude: the height from the center line to the maximum or minimum point.
We can either determine the center line, or we can measure the height between the max to min points and divide that by 2.
From inspection of the graph, the max points are at y = -0.5 and the min points at y = -3.5
Therefore, the distance between them = -0.5 - -3.5 = 3
Divide by 2 = 3/2 = 1.5
Therefore, the amplitude = 1.5
