Answer:
6 points
Step-by-step explanation:
1/10=x/20cross multiply the x with the 10 and the 20 with the 1 so that you are now left with the fraction 10x/2010x divided by 20 will give you x=2to check and make sure this is still equivalent with the 10% of shots Madeline makes divide 2/20Since this is still 10 percent Madeline makes 2 out of every 20 shots Multiply those 2 shots by three points since it was from the three point line and we get 6 pointsHope that helps :)
Using the binomial distribution, it is found that she would be expected to make 6 points.
For each shot, there are only two possible outcomes, either she makes it, or she misses it. The probability of making a shot is independent of any other shot, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
Probability of exactly x successes on n repeated trials, with p probability, which has expected value given by:
[tex]E(X) = np[/tex]
In this problem:
She takes 20 shots, hence [tex]n = 20[/tex].She has a 10% probability of making each shot, hence [tex]p = 0.1[/tex]The expected number of shots she makes is given by:
[tex]E(X) = np = 20(0.1) = 2[/tex]
Since each shot from the three-point line is worth 3 points, she is expected to make 2 x 3 = 6 points.

100 POINTS+BRAINLIEST 8TH GRADE MATH PT 6: SIMPLIFY THE GIVEN EXPRESSION -I know how to do the distributive property but i don't know the rules to remember when dealing with rearranging subtraction sings like the one in the first set of parenthesis. please tell me how to accurately simplify an expression with those subtraction signs
thanks so much!!
Answer:
[tex]-x + 9[/tex]
Step-by-step explanation:
Hello!
We want to combine any like terms and distribute the signs properly to the terms in the parentheses.
First, remove the parentheses by distributing the signs:
[tex]-(2x - 1) + 3(x + 4) - 2(x + 2)[/tex][tex]-(2x) - (-1) + 3(x) + 3(4) - 2(x) - 2(2)[/tex]The simplified form is [tex]-x + 9[/tex].
Another way to think about the negative sign is by replacing it with -1, so essentially you are multiplying the whole parentheses by -1.

you are going to paint the sixth sector spinner shown.There are 4 colors to choose from. How many different ways can u paint this spinner if each color can be used more than once and there are no other restrictions
Answer:
There are 4096 options to choose from.
Step-by-step explanation:
6 sections each with 4 colours to choose from : 4⁶ = 4096
The spinner with 6 different parts and 4 different colors can be painted in 4⁶ ways.
What are permutation and combination?A permutation is an arrangement of things where order matters, AB and BA are two different permutations.
The combination is a selection of things where order does not matter, AB and BA are the same combinations.
Given, you are going to paint the sixth sector spinner shown and there are 4 colors to choose from also each color can be used more than once and there are no other restrictions.
∴ The first part can e painted in 4 different ways and as there are no restrictions every 6 parts can be painted in 4 different ways.
So, the total no. of ways to color this spinner with 6 different parts and 4 different colors are,
4×4×4×4×4×4 ways,
= 4⁶ ways.

The sum of the digits of a two-digit number is 5. If nine is subtracted from the number, the digits will be reversed. Find the number.
If the tens digit is x, then the equation is:
The number is:
Answer: 32
Step-by-step explanation:
The only numbers that can have 2 digits and two of which equal to five can only be:
3+2
2+3
4+1
1+4
So the numbers are: 41,14,23, and 32.
41-9=32
14-9=5
23-9=14
32-9=23
Since the question is asking for the number who’s difference is the reverse of one of the numbers. The only possible answer is 32 because 32-9= 23. (23 is the reverse of 32)

There are 5 blue socks in Josh’s drawer. After he removes 3 non-blue socks, the probability to pick a blue sock at random becomes . How 1/7 many non-blue socks were in Josh’s drawer originally?
Answer: There is 5 non blue sock in Josh's drawer
Step-by-step explanation:
The denominator shows the total of nonblue and blue socks. So there are 7 non-blue and blue socks in the drawer after he removes 3 non blue socks.To find how many non-blue where in the drawer originally you need to find how many non blue are in the draw after removing the three. So you subtract 7 from 5 which gives you 2. So there are 2 non-blue socks in the drawer after removing the three. Now you need to find how many non-blue were there before he removed the three. So add the 3 non blue socks that he removed to the two that were there after which gives you five.

6.) Michael & Melissa both claim to be earning a C average, 70% to 79%, in their Latin Class. Use the table below to explain their reasoning and determine which student is earning a C average.
To figure out the average of Michael and Melissa we must add up all their test scores and divide the by 7; which is the number of tests they took.
Michael:
(80+76+73+70+40+25+10)/7
Melissa:
(88+83+75+70+60+65+62)/7
Michael's average is 53.4
Melissa's average is 71.9
So Melissa is earning a C in Latin.

Which expression is equivalent to 56x-28y + 42?
a.) 8(7x - 3y + 6). b.) 7(8x + 4y +6z)
c.) 7(8x - 4y + 6)
Answer:
Letter c
Step-by-step explanation:
You are distributing the 7 to each term in the parentheses.
7(8x) is 56 x
Here is the tricky part. You can think of it a couple of ways:
7(-4y) = -28y a positive times a negative is a negative.
or 7(4y) = 28 , but then remember that you are subtracting so it will become -28
7(6) = 56
56x - 28y +42
Answer:
c.) 7(8x - 4y + 6)
Step-by-step explanation:
if we solve 7(8x-4y+6), we get;
56x-28y+42

What is the total amount due after 6 months on an initial loan of $1,400 at 12.5% annual interest.
Answer: $1487.50
Step-by-step explanation:
hey there again!
Facts:
Principal (starting amount): $1,400
Annual interest rate: 12.5% of the principal. Whenever you get an annual interest rate as a percentage, its always that percentage of the starting amount.
Time given: 6 months, 1/2 a year
the question asks "total amount due' in 6 months. Basically, we want to know how much they will have in their account after 6 months.
Step 1: Find how much interest he will get in 6 months as a percentage.
6 months is 1/2 of a year, so find 1/2 of 12.5
1/2 of 12.5
1/2 x 12.5
0.5 x 12.5
6.25%
Step 2: Find how much interest he gets, but as a number.
Principal: $1400
6.25% of 1400= $87.50
Step 3: Find the total amount of money he will have after 6 months.
he starts with 1400, and gets an additional $87.50 added to his account after 6 months. How much does he have now?
To answer this, add to find the total:
87.50+1400= $1487.50

how much will you have to pay back in total if you borrowed $400 from the bank for a year at 12%
You would have to pay back $448 in total after one year.
What is the amount on the loan?The simple interest formula can be expressed as;
I = P × r × t
Where I is interest, P is principal, r is interest rate and t is time.
Given the parameters:
Principal P = $400 (the initial loan amount)
Rate r = 12% = 12/100 = 0.12
Time t = 1 year
Interest = ?
To determine the interest, we can use the above formula for simple interest:
I = P × r × t
Interest = $400 × 0.12 × 1
Interest = $48
Money to be paid back will be:
Amount = Principal + Interest
Amount = $400 + $48
Amount = $448
Therefore, the accrued amount to be paid is $448.
