Consider this scatter plot.(a) How would you characterize the relationship between the hours spent on homework and the test
scores? Explain.

(b) Paul uses the function y = 8x + 40 to model the situation. What score does the model predict for 3 h
of homework?

(c) What does the number 40 in Part (b) mean in the context of the situation?

Answers

Answer 1

Answer: A) the more time spent on homework the higher the test score

B) y =8x+40 = y=8(3)+40 = 24+40 = 64

C) 40 would be the test score if no time was spent doing homework

Answer 2

Answer:

Answer:

We have been given the scatter plot:

(a)We can clearly see from the plot that there is direct proportion between the number of hours of homework and test scores.

Direct proportion means if hours of homework increases then test score increases and vice-versa.

(b) we have been given a function y=8x +40

We need to predict for 3 hours of homework put x=3 in above function as x represents hours of homework we get:

y=8(3)+40

y=24+40

y=64

Hence test score will be 64 for 3 hour of homework.

of in mathematics means multiplication
is means the equal sign
lets call out number 'n'
so we have

9 = (1/4)n
9 x 4 = (1/4) x 4 x n
36 = n

so n equals to 36

I need to write an even number between 7 and 16 draw a picture an them write a sentence to explain why it is an even number

Answers

An even number is a number that is divisible by 2.
This means that dividing this number by 2 yields no remainder (the remainder is zero).

The even numbers between 7 and 16 are:
8 as 8/2 = 4 and remainder is zero
10 as 10/2 = 5 and remainder is zero
12 as 12/2 = 6 and remainder is zero
14 as 14/2 = 7 and remainder is zero

Step-by-step explanation:

Which graph represents the function f (x) = StartFraction 2 x Over x squared minus 1 EndFraction?

Answers

By analyzing the asymptotes we can find the graph of the rational function. Also a graph is provided below.

Which graph represents the function?

We have the rational function:

f(x) = (2x)/(x^2 - 1).

First, you can see that we have two zeros on the denominator. One happens when x = 1 and the other when x = -1.

This means that the graph of this function will have two vertical asymptotes at these values. (four actually as we have one going to each end in each point).

With that description we can find the graph of the function, I will also post it so you can recognize it.

Answer:

Step-by-step explanation:

f(x) = 2 / (x^2 - 1) is better written as

f(x) = ------------------

(x - 1)(x + 1)

This is undefined at x = -1 and x = 1; there are vertical asymptotes at x = -1 and x = 1.

The y-intercept is found by letting x = 0; we get

f(x) = ------------------ = -2 => (0, -2)

(0 - 1)(0 + 1)
