Answer:
-4/9
Step-by-step explanation:
The scatter plot shows the relationship between the test scores of a group of students and the number of hours they play computer games in a week: Part A: What is the group of points labeled A called? What is the point labeled B called? Give a possible reason for the presence of point B. Part B: Describe the association between students' test scores and the number of hours they play computer games. I'm giving 20 points for this!!
Answer:
part a - clusters
part b - outlier
That one person couldve been really smart or studied a lot after he played video games
For the most part the less time a student spends on computer games the higher the test score is
Step-by-step explanation:
This problem says to write the product of the sum and the difference. (x+5)(x-5). I'm not sure what my teacher is asking me to do.
Step-by-step explanation:
step 1. x + 5 and x - 5 are polynomials.
step 2. x + 5 is a sum, x - 5 is a difference.
step 3. (x + 5)(x - 5) is a product which means to multiply. So "multiply" using FOIL.
step 4. (x + 5)(x - 5) = x^2 - 5x + 5x- 25 = x^2 - 25.
2. Classify the angle as acute, obtuse, right or straight.
O acute
O obtuse
Oright
straight
HELP ASAP
Answer:
Please include the details of the angle
Step-by-step explanation:
When the angle is 93 degrees, the the angle is a obtuse angle. option B is correct.
Given that the measure of angle A is 93 degrees, we can classify the angle as follows:
Angle A = 93 degrees
We know that if angle is less than 90 degrees, it is acute.
if angle is greater than 90 degrees, it is obtuse.
if angle is equal to 90 degrees, it is right angle.
Since the angle measures greater than 90 degrees, it falls within the range of an obtuse angle.
Therefore, the correct classification for angle A is obtuse.

tan(A—B)=tanA—tanB/1+tanAtanB
Answer:
tan (A−B)=tan(A)−tan(B)/1+tan(A)tan(B)tan(A−B)=tan(A)−tan(B)/1+tan(A)tan(B)
1+tan(A)tan(B) To prove this, we should know that:

Each month Marla pays a $30 cell phone bill from her bank account. At the
end of one year, what is the change in the amount of money in Marla's account
because of her cell phone bill? Write a multiplication equation to represent the
problem. Explain what the product represents.
Answer:
-$360.00 change
Step-by-step explanation:
Now there is either some information missing, like her starting total in the bank; or they want you to explain the net change. But the way the question is worded it is stating she is paying $30 over 12 months. This means she has paid $360.00 in that 12 months aka 1 year. Her bank account should have had a balance. So you could technically say B for balance. B-30*12. To get your answer. Although there are many ways to write an equation expression of this question. If you know the starting balance then it's better. But you could assume her starting balance was $0. Which would be 0-30M*12 where M could represent monthly. And the same answer would occur of 360. Is there more information?
30*12= X (x equals the total paid)
X-30*12 (if x is her balance before paying any money)

Paul has a collection of nickels and
dimes that has
a total value of
& 12.50. He Has 150 coins in all. How
many dimes does paul have?
Answer:
#nickels = 50
#dimes = 100
Step-by-step explanation:
system of equations:
n + d = 150
.05n + .10d = 12.50
let n = '150 - d' and substitute this into the second equation
.05(150-d) + .10d = 12.5
7.5 - .05d + .10d = 12.5
.05d = 5
d = 5/.05
d = 100
n = 50

Matrix A has 2 rows and 3 columns whereas matrix B has3 rows and 2 column
Can AB be multiplied? Can BA be multiplied? Give the reason
Step-by-step explanation:
for any matrix multiplication number of columns of first matrix should be equal to number of rows of second matrix.
For AB
A has 3 columns and B has 3 rows so it matches . Hence can be multiplied.
For BA
B has 2 columns and A has 2 rows it also matches so can be multiplied
