Duane scored 9 out of 11 on his Science homework and 17 out of 20 on his History homework. He concluded that he scored higher in Science
because he got only two answers wrong while in History he got three
answers wrong. Find Duane's percentage score to determine if his
conclusion is accurate

Duane's conclusion is wrong

Step-by-step explanation:

We can calculate the percentage scores by dividing the number of answers right by the total number of questions:

Science homework: 9/11 = 0.82, or 82%

History homework: 17/20 = 0.85, or 85%

So, Duane's conclusion is wrong because his percentage score for history was higher than the one for science.

step-by-step explanation:

i have done this all on a piece of paper but idk how to put it on here cuz it needs to be drawn

the speed is   miles per hour > is false

step-by-step explanation:

we know that  

a relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form or

in a proportional relationship the constant of proportionality k is equal to the slope m of the line and the line passes through the origin

the graph shown in the figure represent a direct variation

the slope of the line represent the speed

for the point

substitute the values of x and y

the linear equation is equal to

statements

case a) it takes hours to go miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct

case b) the speed is   miles per hour

the statement is false

because the speed is

case c) the unit rate for the trip is

the statement is true

because the speed is equal to the slope of the linear equation

case d) it took minutes to go the first miles

the statement is true

because

substitute

for

find the value of y in the linear equation

> is correct
