Options :
A. 0.8d
B. d-0.2
C. d-0.2d
D. 1-0.2d
Answer:
A. 0.8d ; d - 0.2d
Step-by-step explanation:
Given that:
Cost of item = d dollars
Discount on items = 20%
Expression represemting the discounted price :
(100% - 20%) x d
80% * d
0.8d
(100% - 20%) x d
(1 - 0.2)d
d - 0.2d
Jeremiah makes 25% of the three-point shots he attempts. For a warm up, Jeremiah likes to shoot three-point shots until he successfully makes one. Let M be the number of shots it takes Jeremiah to successfully make his first three-point shot. Assume that the results of each shot are independent. Find the probability that Jeremiah's first successful shot occurs on his 3rd attempt. You may round your answer to the nearest hundredth. P(M=3)=
Answer: .14
Step-by-step explanation: Khan Academy
Answer:
0.14
Step-by-step explanation:
First off, please read clearly.
This problem is asking for the probability that (M = 3).
The correct answer for this P(M = 3) problem is 0.14 through Khan Academy.
Even when you solve it, it is 0.14. The equation would be zero point twenty-five multiplied by parenthesis one minus zero point twenty-five closed parenthesis to the power of two. Written out the equation would be the following:
0.25x(1-0.25)^2
*** DO NOT MIX THIS UP WITH A VERY SIMILAR PROBLEM TO THIS. ***
There is a problem using this same Jeremiah situation but it asks for P(M < 4).
If you want the answer for P(M < 4) it is 0.58 so
P(M < 4) = 0.58
And another Jeremiah problem that asks for P(M > 6).
If you want the answer for P(M > 6) it is 0.18 so
P(M > 6) = 0.18
Have a nice day :)

28-3(2+4)+9
With explanation
Answer:
Go through PEMDAS
Step-by-step explanation:
28-3(2+4)+92+4=628-3(6)+96+9=1528-3+1528-3=2525+15=40Answer:
19
Step-by-step explanation:
Result:
28 - 3(2 + 4) + 9 = 19/1 = 19
Spelled result in words is nineteen.
How do you solve fractions step by step?
Add: 2 + 4 = 6
Multiple: 3 * the result of step No. 1 = 3 * 6 = 18
Subtract: 28 - the result of step No. 2 = 28 - 18 = 10
Add: the result of step No. 3 + 9 = 10 + 9 = 19

Find angles a, b and c?
Please help.
Answer:
B=112 degrees A=68 degrees and C=68 degrees
Step-by-step explanation:
the opposite angle of the 112-degree angle is the angle on the top left of the page, this means both of the angles are the same. You can then tell that that angle is the same as the one across from it because it shows on the page. You can then figure out the opposite angle which is B so that means angle B is equal to 112 degrees. To figure out angle A you can just do 180 minus the angle B which is 112 degrees. You now know angle A which is 68 degrees, now to find the angle C you just have to notise that angle C is the opposite angle of angle A. This means that algle C is also 68 degrees.
Answer:
a=112
b=68
c=112
Step-by-step explanation:
Oliver, Lily, and Ella are hoping to save money. Oliver thinks saving money in a shoe box in his closet every month is a good idea. He decides to start with $150, and then save $75 each month. Lily was given $4000 from her Great Uncle Merv, and decides to put the money into an account that has a 7% interest rate that is compounded annually. Ella has earned $4500 working at the gas station and decides to put her money in the bank in an account that has a 7.5% interest rate that is compounded continuously. Part 1: Describe the type of equation that models Oliver’s situation. Create that equation of Oliver’s situation. Using the equation you created, how much
money will be in Oliver’s account after 2 years? 10 years?
1. What is being asked in the problem and what does that mean?
2.What do you know and what does it mean? What plan are you going to try?
3. Write out your thinking and work.
4. Write out your response to the question, explaining your answer and what it means.

This is for the algebra 2 portfolio, Algebra 2 B Unit 3 Lesson 7: Viruses and Viral Videos Portfolio
Answer:
Step-by-step explanation:
Part 1:
1. What is being asked in the problem and what does that mean?
Oliver is meaning to save more money than Lilliana
2.What do you know and what does it mean? What plan are you going to try?
It means that Oliver is trying to be reponsible and save money for a nice house. Use an equalizer and solve it.
3. Write out your thinking and work.
Since Olivier saves 150 per month, we multiply that with the number of years and then subtract the $75 he already saved up (since we only need to calculate the amount that he saved over the months.
2 yr of months: 150x30 -75 = 4480
10 yr of months: 150x180 - 75 = 21,993
4. Write out your response to the question, explaining your answer and what it means.
2 months of years: $4480
10 months of years: $21993
Part 2:
1. What is being asked in the problem and what does that mean?
Liliana needs to save money and we are asked to help her.
2.What do you know and what does it mean? What plan are you going to try?
It means that we have to use an equalizer to give to her so she can save the money over the years.
3. Write out your thinking and work.
Use formulaic methods. Since she has interest on her money, we have to include it:
i = log(x-4*7)^k
i is the interested amount, x is the variable we use, and k is the number of times. 7 is the interest
i = log(4000-4*7)^2 for 4000 at 7% interest over 2 years
i = log(4000-4*7)^10 for 4000 at 7% interest over 10 years
4. Write out your response to the question, explaining your answer and what it means.
Amount after 2 years: $30,000
Amount after 10 years: $15,671
Part 3:
1. What is being asked in the problem and what does that mean?
How we can help Ella save for her college.
2.What do you know and what does it mean? What plan are you going to try?
We can try using formulaic methods like we did for Dan in the previous assignment.
3. Write out your thinking and work.
l = (a/b)^q where l is the amount saved, a is the initial amount of dollars, b, is the time, and q is the interest
2 years: (4500/2)^4.5 = 2,500
10 years: (4500/10)^4.5 = 40,650
4. Write out your response to the question, explaining your answer and what it means.
After 2 years: $2500
After 10 years: $40,650

A record sells for $7.98. Johann bought one on sale for $5.98. Estimate the amount saved as a percent of the regular price.
Answer:
25.06%
Step-by-step explanation:
We can use the percentage formula for this problem:
p = 100(y/x)
Let's simplify it:
p = 100(5.98/7.98)
p = 100(0.7494)
100 * 0.7494 = 74.94
100.00 - 74.94 = 25.06
Therefore, Johann saved 25.06% on the record.

Rectangle P is a scale drawing of rectangle F using a scale factor of 150%. The area of rectangle F is 32 square units. What is the area of rectangle P?
Limit you answer to digits only
Answer:
128 square units
Step-by-step explanation:
At first I thought it would be as simple as 150% of 32 = 48.
Then I thought about increasing the sides of the rectangle 150% and that would make it 4 times larger.

The perimeter of the square below can be described by the expression 64 + 12y.
A square.
Which of the expressions describes the length of one side of the square?
A square has 4 equal sides.
64/4 = 16; 12 y/4 = 3 y
16 + 12y
4 + 12y
4 + 3y
16 + 3y
Answer:
the answer would be 16+3y
Step-by-step explanation:
length of one side of a square is perimeter/4
so (64+12y)/4
64/4 +12y/4
=16+3y
