The positive number a is 2,352% of the sum of the positive numbers b and c, and b is 84% of c. What percent of b is a?
Answer: We can start by using the information given to set up an equation. We know that:
a = 2,352% of (b + c)
b = 84% of c
We can express the first equation in terms of percentages by dividing both sides by 100:
a = 23.52(b + c)
We can also express the second equation in terms of percentages by dividing both sides by 100:
b = 0.84c
Now we can substitute the second equation into the first equation:
a = 23.52(0.84c + c)
a = 23.52(1.84c)
So a = 43.1184c
To find the percentage of b, we divide b by a and multiply by 100:
percentage of b = (b / a) * 100
Now we substitute values of a and b
percentage of b = (0.84c / 43.1184c) * 100
percentage of b = (0.84 / 43.1184) * 100
Which simplify to
percentage of b = 1.9425 %

Seven television sets are chosen at random (i.e without replacement) from a shipment of 240 television sets of which 15 are defective. Calculate the probability that at least 1 of the chosen televisions are defective
Answer:
7/16
Step-by-step explanation:
Probability calculates the likelihood of an event occurring. The likelihood of the event occurring lies between 0 and 1. It is zero if the event does not occur and 1 if the event occurs.
For example, the probability that it would rain on Friday is between o and 1. If it rains, a value of one ids attached to the event. If it doesn't a value of zero is attached to the event.
Proportion of defective televisions in the shipment = 15/240 = 1/16
Probability that 1 of the 7 chosen is defective = 1/16 x 7 = 7/16

University officials hope that changes they have made have improved the retention rate. Last year, a sample of 1937 freshmen showed that 1517 returned as sophomores. This year, 1636 of 2038 freshmen sampled returned as sophomores. Determine if there is sufficient evidence at the 0.05 level to say that the retention rate has improved. Let last year's freshmen be Population 1 and let this year's freshmen be Population 2. Step 2 of 3: Compute the value of the test statistic. Round your answer to two decimal places.

Delpha buys 20 packs of gum. Three fifths of the packs contain bubble gum. How many packs of bubble gum does Delpha buy?
Answer:
12
Step-by-step explanation:
Find 3/5 of 20, or 60% of 20
60%=0.60
0.60*20=12
So Delpha buys 12 packs of bubble gum.

In discreet measurements only take the whole numbers within a permitted range. For example, count of people, number of objects etc. Ordinary, logically ordered categorical values. For example, the size of clothes,
Nominal measurements include not logically ordered categorical values. For example, nationality, language etc. The scale of measurements most reasonably applies to Confidence in Science is ordinal.

A Norman window is a window with a semi-circle on top of regular rectangular window. (See the picture.) What should be the dimensions of the rectangular part of a Norman window to allow in as much light as possible, if there are only 12 ft of the frame material available? I'm reporting you if you send be a bitly link
Answer:
length = 4 feet, and width = 2 feet
Step-by-step explanation:
Given that 12 feet of the frame material is available for the rectangular part of Norman's window. Then,
Perimeter = 2 (length + width)
Perimeter of the frame = 12 feet
So that,
Perimeter = 2 (length + width)
12 = 2 (length + width)
length + width = [tex]\frac{12}{2}[/tex]
length + width = 6 feet
Therefore, to allow much light as possible, the dimensions of the window would be; length = 4 feet, and width = 2 feet.
Susan invested a total of $9000 in two accounts. One account pays 3% interest and the other account pays 6% interest. The total return from both accounts was $450.
The money invested in a account with 3% interest is $3000 and the money invested in a account with 6% interest is $6000.
What is the simple interest?Simple interest is a method to calculate the amount of interest charged on a sum at a given rate and for a given period of time.
Simple interest is calculated with the following formula: S.I. = (P × R × T)/100, where P = Principal, R = Rate of Interest in % per annum, and T = Time.
Given that, Susan invested a total of $9000 in two account.
One account pays 3% interest and the other account pays 6% interest.
Let the money invested in a account with 3% interest be x.
Then, the money invested in a account with 6% interest be 9000-x.
The total return from both accounts was $450.
Here, (x×3×1)/100 + ((9000-x)×6×1)/100 =450
3x+54000-6x=45000
54000-3x=45000
3x=9000
x=$3000
So, 9000-x=$6000
Therefore, the money invested in a account with 3% interest is $3000 and the money invested in a account with 6% interest is $6000.
