In 15 years, the account will be worth $1896 if the 3.7% interest is compounded monthly on initial deposit of $1100.
What is compound interest?It is the addition of interest to the principal sum of a loan or deposit, or in other words, interest on principal plus interest.
Given Data
A = [tex]P(1+\frac{r}{100} )^{t}[/tex]
P=$1100
r =3.7%
t = 15years
Substitute the values in formula, A = [tex]P(1+\frac{r}{100} )^{t}[/tex]
A= 1100(1+{3.7/100})¹⁵
A = 1100(1+0.037)¹⁵
A = 1100(1.037)¹⁵
A= 1100(1.724)
A= 1896.4
Round off to nearest cent - $1896
Hence, $1896 will the account be worth in 15 years

Determine whether the following possible responses should be classified as interval, nominal, ratio or ordinal data The starting salaries of new phd graduates from a statistics program
The starting salaries of new phd graduates from a statistics program illustrates a ratio data.
How to explain the information?The four basic levels of measuring scales—nominal, ordinal, interval, and ratio are used to collect data in the form of multiple-choice questions on surveys and questionnaires.
Each scale serves the same purpose as the preceding scale, and all survey question scales are incremental levels of measurement.
Nominal: the data can only be categorized.
Ordinal: the data can be categorized and ranked.
Interval: the data can be categorized and ranked, and evenly spaced.
Ratio: the data can be categorized, ranked, evenly spaced and has a natural zero.
Therefore, the starting salaries of new phd graduates from a statistics program illustrates a ratio data.

Answer:
2A/h = b
Step-by-step explanation:
To get b by itself, you have to reverse each operation for the other variables.
h is being multiplied by b here, so to reverse it, you would divide h on both side of the equation. This will give you...
A/h = 1/2b (h is not on the right side anymore because it got canceled out.)
Next you will get rid of the 1/2 by multiplying both sides of the equation with the reciprocal. The reciprocal of 1/2 is 2/1. This will give you..
2A/h = b (1/2 is not on the right side anymore because it got canceled out by 2/1 (1/2 x 2/1 = 1))
Step-by-step explanation:
this is the formula for the area of a triangle :
half off the baseline times the height (to this baseline).
to solve an equation for one variable involved means to end up with only that variable on one side, and everything else on the other side.
the whole time we keep the equality alive, so any change done on one side has to be done on the other side as well.
A = 1/2 × b × h
to solve for b means we want to get rid of the 1/2 and the h factor.
let's start with the 1/2 factor : we multiply both sides by 2.
2A = b × h
and to get rid of h, we need to divide both sides by h :
2A/h = b
and that's it.
Ken received his bank statement in the mail and checked it to verify his recent pay increase.
Ken has direct deposit so his paycheck is sent electronically to his account. The previous
month's pay was $5,320.10. Ken's account activity showed a $651.22 previous balance,
checks of $5,211.39, ATM withdrawals of $250 and a service charge of $4.50. If Ken's new
balance is $982.01, what increase in pay was direct deposited?
The pay increase that was directly deposited into Ken's account is $476.58.
In the question, we are asked to find the pay increase, that was directly posited in Ken's account, given that Ken received his bank statement in the mail and checked it to verify his recent pay increase. He has direct deposit so his paycheck is sent electronically to his account. The previous month's pay was $5,320.10. His account activity showed a $651.22 previous balance, checks of $5,211.39, ATM withdrawals of $250, and a service charger of $4.50. Also, we are informed that his new balance was $982.01.
We assume the pay increase to be $x.
Thus, his this month's pay will be $(5,320.10 + x).
This will be added in his previous month's balance, to get $651.22 + $(5,320.10 + x) = $(5,971.32 + x).
Now, the check of $5,211.39, ATM withdrawal of $250, and the service charge of $4.50 will be deducted from this to get $(5,971.32 + x) - $5,211.39 - $250 - $4.50 = $(505.43 + x).
This is the final balance of Ken's account.
But, we are given that Ken's new balance was $982.01.
Thus, we get an equation 505.43 + x = 982.01, which can be solved by subtracting 505.43 from both sides to get:
505.43 + x - 505.43 = 982.01 - 505.43,
or, x = 476.58.
Thus, the pay increase that was directly deposited into Ken's account is $476.58.

Based on the given parallelogram, a height of 5 units long as estimated by Leon is not reasonable.
What is the height of the parallelogram?The height of the parallelogram can be found by counting the number of squares from the base of the parallelogram to the top. The squares are given in the graph which is shown attached.
When this counting is done, we get 6 squares.
6 units is therefore the height of the parallelogram which means that Leon's estimate of 5 units is therefore not reasonable.

A student takes out 2 loans to pay for college. One loan at 9% interest and the other at 12% interest.
The total amount borrowed is $65,000, and the interest after 1 year for both loans is $6,360.
Find the amount of each loan.
The loan amount at 9% interest is $48,000.
The loan amount at 12% interest is $17,000
What are the loan amounts?The first step is to form a system of equations that can be used to determine the required values:
0.09a + 0.12b = $6,360 equation 1
a + b = $65,000 equation 2
Where:
a = amount of the loan at 9% interest
b = amount of the loan at 12% interest
What is each loan amount?Multiply equation 2 by 0.09
0.09a + 0.09b = 5850 equation 3
Subtract equation 3 from equation 2
0.03b = 510
Divide both sides of the equation by 0.03
b = 510 / 0.03
b = $17,000
Subtract 17,000 from 65,000
a = 65,000 - 17,000
a = $48,000

3(2x+2)-3x= 6+3x you have to distribute the 3 (which you did correctly.)
6x+6-3x=6+3x
what you did wrong was canceling out the threes. you cannot cancel out the threes here because the one on the left is negative. What you should do is add 3x to each side like this.
6x+6-3x=6+3x

6x+6=6+6x
since both sides are equal and we obtain 0=0, this means the equation is in fact an identity which is true for all values of x.

Zachary Company reported the following data regarding the product it sells: Sales price $48 Contribution margin ratio 25% Fixed costs $336,000 Required Use the contribution margin ratio approach and consider each requirement separately. What is the break-even point in dollars? In units?
Answer:
The break-even point in dollars is 1,344,000 and in units is 28,000. The break-even point is calculated by dividing the fixed costs by the contribution margin. In this case, 336,000 ÷ .25 = 1,344,000. The break-even point in units is then calculated by dividing the break-even point in dollars by the sales price. In this case, 1,344,000 ÷ 48 = 28,000.

Diana, Elsa, Flora and Hannah agreed to share the cost of a present equally for their mother. Hannah did not bring her money so the other 3 sisters paid for her share. Flora paid 4/5 of what Diana and Elsa paid. Diana paid $10 less than Elsa. The ratio of Diana and Elsa share is 1:4. When they reached home, Hannah returned her sisters' their share of money. Hannah returned Flora $84. (a) How much did Diana and Elsa pay altogether? (b) How much did Hannah pay Diana?
Using proportions, it is found that:
a) Diana and Elsa paid $105 altogether.
b) Hannah paid Diana $21.
What is a proportion?A proportion is a fraction of a total amount, and the measures are related using a rule of three. Due to this, relations between variables, either direct(when both increase or both decrease) or inverse proportional(when one increases and the other decreases, or vice versa), can be built to find the desired measures in the problem, or equations to find these measures.
Hannah returned Flora $84, and Flora paid 4/5 of what Diana and Elsa paid, hence the amount Diana and Elsa received by Hannah is given as follows:
4/5x = 84
0.8x = 84
x = 84/0.8
x = 105.
Hence Diana and Elsa paid $105 altogether.
For item b, we have that the ratio of Diana and Elsa share is 1:4, hence Diana got 1/5 of the amount paid by Hannah, hence:
1/5 x 105 = 21.
Hannah paid Diana $21.

What are Kyle's monthly repayments?
The monthly repayment Kyle has to pay on the television based on the hire purchase agreement is R229.
What is the monthly repayment?The monthly repayment is the amount to be paid monthly with interest on the given loan amount.
We have,
Price of the television = R5600
Deposit amount:
= 15% of 5600
= 15/100 x 5600
= 0.15 × 5600
= 840
Now,
The remaining amount:

The monthly repayment amount of 14% per annum is:
A = [ P( R/12 )( 1 - R/12 [tex])^{n}[/tex] ] / ( 1 + r/12 [tex])^{n}[/tex] - 1
