Mr. Moore deposits $3,550 in a money market account with an interest rate of 22%. If he does not deposit or withdraw any money from the account, how much will he have at the end of 9 months?
Answer:
$10,579, assuming that 22% is the rate per month
Step-by-step explanation:
Here, I'll assume that the interest rate is per month.
The simple interest formula is [tex]I=Prt[/tex] (Interest = principal * rate * time). The rate and time need to use the same units.
The principal is $3550, the rate is 0.22, and the time is 9, so [tex]I=(3550)(0.22)(9)[/tex]. The product is 7029.
This is added to how much money he already has: 7029+3550=10579

Refer to the Exhibit Student Grades. The professor has informed the class that 7.93 percent of her students received grades of A. What is the minimum score needed to receive a grade of A
This question is incomplete, the complete question is;
Refer to the Exhibit Student Grades. A professor at a local university noted that the grades of her students were normally distributed with a mean of 73 and a standard deviation of 11.
The professor has informed the class that 7.93 percent of her students received grades of A. What is the minimum score needed to receive a grade of A
Answer:
the minimum score needed to receive a grade of A is 88.51
Step-by-step explanation:
Given the data in the question;
Let x represent the grades of the students that were normally distributed with mean μ = 73 and standard deviation σ = 11.
so, The professor has informed the class that 7.93 percent of her students received grades of A
the minimum score needed to receive a grade of A will be:
P( X > x ) = 7.93 %
P( X > x ) = 0.0793
1 - P( X ≤ x ) = 0.0793
- P( X ≤ x ) = 0.0793 - 1
- P( X ≤ x ) = - 0.9207
P( X ≤ x ) = 0.9207
⇒ P( X-μ/σ ≤ x-μ/σ ) = 0.9207
so, x-μ/σ = InvNormal( 0.9207 )
x-μ/σ = 1.41
(x - 73) / 11 = 1.41
(x - 73) = 1.41 × 11
(x - 73) = 15.51
x = 15.51 + 73
x = 88.51
Therefore, the minimum score needed to receive a grade of A is 88.51

What is twice the difference of a number and 6 is 5
Answer:
8.5
Step-by-step explanation:
Twice the difference of a number and 6 equals 5 is written algebraically as 2(x-6)=5, where x is the number. Solving for x:
2(x-6)=5
(x-6)=5/2
x=6+5/2
x=17/2
So the number is 17/2, or, expressed as a decimal number, 8.5
Use the Distributive Property to solve the equation.
3 = 3/4 ( b - 8 )
Answer:
b = 12
Step-by-step explanation:
First, distribute 3/4 to both terms in the parentheses:
3 = 3/4(b - 8)
3 = 3/4b - 6
Now, solve for b:
9 = 3/4b
12 = b
So, the answer is b = 12
Answer:
12
Step-by-step explanation:
3 = 3/4 x (b-8)
Distribute 3/4 through the parentheses
3 = 3/4 b - 6
Multiply both sides of the equation by 4
12 = 3b - 24
Move the variable to the left - hand side and change its sign
-3b = -24 - 12
Calculate the difference
-3b = -36
Divide both sides of the equation by -3
B = 12

Consider this Revenue Advertising Expense situation.
A drugstore that sells a certain brand of vitamin capsule estimates that
the profit P (in pesos) is given by P = −50x³ + 2400x² − 2000, 0 ≤ x ≤ 32 where x is the amount spent on advertising (in thousands of pesos). An
advertising agency provides four (4) different advertising packages with
costs listed below.
Which of these packages will yield the highest revenue
for the company?
A. Package A: Php 8,000.00

Answer:
3/8
Step-by-step explanation:
you have to find the LCM (least common multiplier) of 2,and 8 and that would be 8 therefore youd change the fractions from 1/2-1/8 to 4/8-1/8 you subtract the tops and keep the bottoms the same as 8. so 4-1=3 therefore the anwser would be 3/8

A verandah of width 2.25 m is constructed all along outside a room which is 5 m long and 3 m wide. Find:
(1) the area of verandah and
(ii) the cost of cementing the floor of verandah at the rate of 7 275 per m².
who answers first will be marked as brainliest iam serious no scam
Answer:
(i)The length of room = 5.5 m and width of the room = 4 m
The length of room with verandah = 5.5 + 2.25 + 2.25 = 10 m
The width of room with verandah = 4 + 2.25 + 2.25 = 8.5 m
Area of verandah = Area of room with verandah – Area of room without verandah = Area of ABCD – Area of EFGH = (AB x AD) – (EF x EH) = (10 x 8.5) – (5.5 x 4) = 85 – 22 = 63 m2
(ii) The cost of cementing 1 m2 the floor of verandah = Rs 200 The cost of cementing 63 m2 the floor of verandah = 200 x 63 = Rs 12,600

The class sells them for $2.95, assuming $0.95 manufacturing cost per, leaving $2.00 profit per bag. If they sell 900-1000 packages at $2.00, it leaves $1800-$2000 profit.
Answer:
if you see they have 2.95 and 0.95 you need to combert to a decimal and then you need to subtract 900 and 1,000
