The principal amount for account A is $200 and for account B is $700.
Account B earns more simple interest than account B in first month.
Given,
Account A
Simple interest, SI = $9.25
Time period, T = 15 months = 1 1/4 = 5/4 years
Rate of interest, R = 3.7%
Account B
Simple interest, SI = $25.20
Time period, T = 18 months = 1 1/2 = 3/2 years
Rate of interest, R = 2.4%
We have to find the principal amount for each account and also the account which earned the more simple interest;
Here,
Simple interest, SI = PRT/100
P is the principal amount
Now,
Account A.
Principal amount,SI = PRT/100
9.25 = (P × 3.7 × 5/4) / 100
9.25 × 100 = P × 4.625
P = 925/4.625
P = $200
Simple interest for first month,SI = PRT/100
SI = (200 × 3.7 × 1/15) / 100
SI = 2 × 3.7 × 1/15
SI = $0.493
Next,
Account B
Principal amount,SI = PRT/100
25.20 = (P × 2.4 × 3/2) / 100
25.20 × 100 = P × 3.6
P = 2520/3.6
P = $700
Simple interest for first month,SI = PRT/100
SI = (700 × 2.4 × 1/18) / 100
SI = 7 × 2.4 × 1/18
SI = $0.933
Here,
The principal amount for account A is $200
The principal amount for account B is $700
Simple interest for first month;
Account A = $0.493
Account B = $0.933
Therefore,
In first month account B earns more simple interest than account A.

yard of fabric. The fabric costs $8 per yard.
You'll apply properties of multiplication in the following steps to find the total cost of the fabric.
1. Use multiplication to write an expression for the amount of fabric needed to make 13 pairs of wings. (2 points)
2. Multiply the amount of fabric by the price per yard to find an expression for the total cost.(2 points)
3. Use the associative and commutative properties to rearrange the terms in the expression to make it easier to calculate. Explain why the rearranged expression is easier to work with. (3 points)
4. Simplify your expression to find the total cost. Show your work. (3 points)
1) An expression for the amount of fabric needed to make 13 pairs of wings is; 3/4 * $8 = $6 each
2) An expression of the total cost is; 3/4 * $8 * 13 = $78
3) The way we will use associative and commutative properties is to start by treating 1 yard of fabric like the fraction 4/4.
4) Simplifying equals $78
How to solve algebra word problems?We are told that each pair of wings is made with 3/4 yard of fabric. Since the fabric costs $8 per yard. Thus;
1) 3/4 * $8 will give us the cost of the amount required for 3/4 yard of fabric. 3/4 * $8 = $6 each
2) Now, we are told that Mr. Townsend needs to make 13 pairs of butterfly wings and as such;
Amount needed to make 13 pairs is expressed as; 3/4 * $8 * 13 = $78
3) Treat 1 yard of fabric like the fraction 4/4.
Now, if this 1 fabric is equal to $8, then it means that 3/4 of the fabric will be $6. That is for one pair of butterfly wings, there's 13 of those so multiply $6 by 13.
This pattern is easier because we know how much 1 fabric costs, but we don't know what 3/4 of it does, so we treat 1 yard of fabric as the fraction 4/4.
4) Simplifying the expression gives; $78

I have a triangle with c as hypotenuse, b as opposite, and nothing for adjacent. Bottom left corner is 62 degrees and the right bottom corner is 90 degrees. Round answer to nearest 16th of an inch
Question is incomplete. Answering in a general way;
The side CA has a length of [tex]\sqrt{c^{2}-b^{2} }[/tex] and Angle C is of 28 degrees.
Given,
Right angled triangle ABC
Length of side AB = b
Length of side BC = c
Angle B = 62°
Angle A = 90°
We have to find the length of side CA and Angle C;
Here,
According to Pythagorean theorem,
Hypotenuse = [tex]\sqrt{base^{2}+altitude^{2} }[/tex]
Here,
Altitude = [tex]\sqrt{Hypotenuse^{2} -Base^{2} }[/tex]
CA = [tex]\sqrt{c^{2} -b^{2} }[/tex]
Now,
Sum of interior angles of a triangle is 180°
Then,
∠A + ∠B + ∠C = 180°
So,
90° + 62° + ∠C = 180°
∠C = 180° - 152°
∠C = 28°

The percentage is calculated by dividing the required value by the total value and multiplying by 100.
The population has increased by 51.56% from last year to this year.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Number of population last year = 2,639,000,000
Number of population this year = 3,999,635,444
The best estimate of the total population of last year and this year.
= [ (3,999,635,444 - 2,639,000,000) / 2,639,000,000 ] x 100

Since the random sample of 200 patients are classified irrespective of their health conditions , as to whether or not they took an omega-3 fish oil tablet daily
what is random sample ?The most basic random sample gives each unit in the population an equal probability of being chosen.
calculation
The study in question is an observational one. No treatments were used in the study because there were none.
b) Since the 200 patients who made up the random sample were divided into groups without regard to their physical health.
When patients are divided into groups at random, it may be discovered that one group's patients are in better health than the other. The results then might become skewed. Therefore, our study's conclusion might be false.
c) The outcomes of this study cannot be generalized.
We cannot determine the actual cause of the elevated cholesterol level because the study is observational. The conclusions of an observational study cannot therefore be generalized.

Given,
In the question:
There are some colored pins in a bag. The pins can be green, yellow, purple, or grey. A pin is going to be taken at random from the bag.
The table shows the probabilities of picking a purple or grey pin.
The table is not given in the question :
So, The table is :
Colors: Green Yellow Purple Grey
Probability: 0.35 0.25
To find the :
a)Complete the table.
There are 14 purple pins in the bag.
b)Work out how many green pins are in the bag.
Now, According to the question:
The probability is the ratio between the possible outcomes over the total outcomes:
The value of the probability of possible outcomes is greater than 0 and smaller than 1 (0 < P < 1)
The sum of the probabilities of all outcomes must equal 1.
A bag contains some green, yellow, purple and grey pins
∵ The probability of picking a purple pin P(purple) = 0.35
The probability of picking a grey pin P(grey) = 0.25
→ The total of all possible outcomes is 1
The sum of the probability of green and yellow pins = 1 - 0.35 - 0.25
The sum of the probability of green and yellow pins = 0.4
P(green) + P(yellow) = 0.4 ⇒ (1)
∵ The probability of picking a green pin is 3 times the probability
of picking a yellow pin
P(green) = 3 P(yellow) ⇒ (2)
→ Substitute (2) in (1)
3 P(yellow) + P(yellow) = 0.4
4 P(yellow) = 0.4
→ Divide both sides by 4
P(yellow) = 0.1
The probability of picking a yellow pin is 0.1
→ Substitute P(yellow) in (20 by 0.1
P(green) = 3(0.1)
P(green) = 0.3
The probability of picking a green pin is 0.3
Green = 0.3, Yellow = 0.1
There are 14 purple pins in the bag
P(purple) = 0.35
0.35 of purple pins = 14
→ To find the total number of pins in the bag divide 14 by 0.35
The total number of pins = 14 ÷ 0.35
The total number of pins = 40 pins
P(green) = 0.3
The number of green pins = 0.3 × 40
The number of green pins = 12 pins
Hence, There are 12 green pins in the bag.
