Answer:
A.)
the correlation between the number of hours students spent studying and the score on the science test seems to be that the people who spent more time studying got a better score than the people who didn't/ did less.
B.)
y = a - b ^x
a = 57
b = 5
because every .5 hours adds 5 points to the score
y = 57 (5) ^x
and as a function
F(x)= 57(5)
C.)
slope: 10
y / x
5 / 0.5
= 10
y-intercept: 57
x is 0 and y is 57 that is the y-intercept
it has a positive slope.

Joe and Josh each want to buy a video game. Joe has $14 and saves $10 a
week. Josh has $26 and $7 a week. In how many weeks will they have the
same amount?
pls help and give a step by step explanation
Answer:
Number of week they have same amount = 4 week
Step-by-step explanation:
Given:
Amount Joe have = $14
Joe's saving per week = $10
Amount Josh have = $26
Josh saving per week = $7
Find:
Number of week they have same amount
Assume;
Number of week they have same amount = a
So,
(14 + 10a) = (26 + 7a)
3a = 12
a = 4
So,
Number of week they have same amount = 4 week

A rectangular poster has an area of 38 square feet. It is 4 3/4 feet wide at its base. What is the height of the poster? HELP I NEED ANSWERS QUICK
Answer:
8
Step-by-step explanation:
The formula for area is length x width or length x height, height and width mean the same thing in some problems such as this one. To find the height, you need to divide the area by the width. 38 divided by 4 3/4 = 8.

54 divided by 7 is???
[tex] \implies \sf \boxed{ \sf7.71}[/tex]
The remainder is 5 when 54 is divided by 7.
What is Division?Division in mathematics is the process of dividing an amount into equal parts. For instance, we may split a group of 20 people into four groups of 5, five groups of 4, and so on.
Given:
We have to divide 54 by 7.
So, the division is
7 | 54 | 7
49
-_____
5
Then, the remainder is 5 because we do not have number further and 5 is smaller than divisor.

What is (f +g)(y) for the functions
look at the picture for answer choices :)
Answer:
B
Step-by-step explanation:
Remark
I'm not sure why (f + g)x is there at all. All you are instructed to do is add the two given functions together.
Solution
(f+g)y = 5x^2 - 2y + 1 - 3y^2 - y - 2
(f+g)y = 2y^2 - 3y - 1
That's B

find the value of given expression
[tex] \sqrt{99 \times 33 \times 3} [/tex]
Answer:
√{99×33×3}=√{33×3×33×3}=√(33²×3²)=±33×3=±99
Answer:
99
Step-by-step explanation:
Cause 33×3=99 ,and the function of the root is to get the number that we multiply it ti itself
For example [tex]\sqrt{4}[/tex] =2 cause 2×2=4 ,so[tex]\sqrt{2*2}[/tex] =[tex]\sqrt{4}[/tex] which is =2
so [tex]\sqrt{99^{2} }[/tex] =99

(11y-36)°
63°
Solve for y
Answer:
y = 9°
Step-by-step explanation:
Vertical Angles law
63° = 11y - 36
63+36 = 99
11y = 99
y = 9
The measures of the angles of a triangle are shown in the figure below. Find the
measure of the largest angle.
Answer:
largest ∡ = 81°
Step-by-step explanation:
44 + 3x - 11 + 4x - 7 = 180
7x + 26 = 180
7x = 154
x = 22
4(22)-7 = 81

Answer:
4
Step-by-step explanation:
30*4=120 because 12=3*4 and 30*4 is basically 3*4*10, and since it's asking for the scale factor, we test to see if 12*4=48, which it does.

Write the equation of the line in fully simplified slope-intercept form.
Answer:
y = 1/2x + 1
Step-by-step explanation:
The slope is the change in y over the change in x. The line goes down one and two left, making the slope 1/2.
The line crosses the y axis at positive 1 and that is the y-intercept.

SOMEONE PLEASE HELP ME ILL GIVE YOU BRAINLY IF YOU GET IT RIGHT!!!!
Answer:
A
Step-by-step explanation:
Answer:
C
Step-by-step explanation:
1. P(E)>P(D) (Event E is more likely to occur, therefore it has a greater probability)
2. P(E)>0.5 (The probability of event D is given as 0.5, so rewrite P(D) in the inequality)
3. 0.5 is equal to 0.5 and 0.1 is less than 0.5, so you can rule out options A and D
4. This leaves us with options 1.5 and 0.9, but it is impossible to have a probability that is greater than equal to one, so you can immediately rule out B
5. After this elimination process, the only remaining answer is C) P(E)=0.9
If y is directly proportional to x and y = 17.5 when x = 21.
