Help Pls. The Number Of Questions That Students Missed On A 50 Question Science Midterm Is Represented

Answers

Answer 1

Answer: Read the step by step to learn and find the answer.

Step-by-step explanation:

We know that to grade something by percentage missing a certain amount of questions effects your grade. Think back to your last test. Maybe you got 3 or 4 wrong and ended up getting an 80 percent. Here we are going based off 50 questions. We know that if we get 19 questions wrong out of 50 we would get a 62%. If we got 14 wrong we would have a 72%. 9.5=81%. 6=88% and 4=92%. We already know the answer is NOT d or c because each section of the box and whisker is 25%. This means that the answer is 100% B. Especially because they asked what was most likely true and none of the other answers matched up.

Linear function f is shown in the graph. Write the slope-intercept form of the equation representing this function.

Answers

Y=3x-7 more characters because the app won’t let me put only the answer

The equation representing the function f(x) -

y = 4x - 8

We have a linear function f(x) as shown in the graph.

We have to determine the slope-intercept form of the equation representing this function.

What is the Slope - intercept form of the equation of a straight line ?

The Slope - intercept form of the equation of a straight line is as follows -

y = mx + c

where -

m - slope of line

c - intercept of line on y - axis.

According to the question, we have -

c = - 8 = intercept of line on y - axes.

Intercepting coordinates on  y - axes = (0, -8).

Intercepting coordinates on x - axes = (2, 0).

Slope = m = [tex]\frac{-8-0}{-2 -0}[/tex] = 4

Therefore, the equation representing the function f(x) -

y = 4x - 8.

Given that,

Wyatt invested $1,600 in an account paying an interest rate of 52% compounded annually.

Wyatt amount after 17 years is computed as,

                   [tex]Amount=1600*(1+\frac{52}{100} )^{17}\\\\Amount=\$ 1974517.5[/tex]    

Joshua invested $1,600 in an account paying an interest rate of 47%

compounded quarterly.    

Joshua amount after 17 years is computed as,

             [tex]Amount=1600*(1+\frac{47}{100} )^{17}\\\\Amount=\$ 1118187.6[/tex]

Wyatt have more money as compared to Joshua,

              1974517.5 - 1118187.6 =  $ 856329.9

Answers

Answer:

(-3,13) (-2,10) (-1,7) (0,4) (1,1) (2,-2) (3,5) (4,8)  are your graph points.

Step-by-step explanation:

Okay so to find the points, you have to create a table graph with a set of x values.

in this case, your equation y=-3x+4 the x can be replace with a set of numbers and these will be your plots.

-3(-3)+4= 13

-3(-2)+4= 10

-3(-1)+4= 7

-3(0)+4= 4

-3(1)+4= 1

-3(2)+4= -2

-3(3)+4= -5

-3(4)+4= -8

Naturally with these points a shape will form ideally a straight line. Hopefully this helps and good luck!

To find slope on the graph you use rise/run like #1 you go up 3 and across 2 so it’s 3/2 and positive because the line is going up if it were going going down it’s a negative slope…now to find it with the formula it says it right there y2-y1 over x2-x1 for example 14-10 over -7-8 and simplify if you can…on the table you will do the same as you did with the formula on #15 you will use the formula like this 2-5 over -2+3 because we all know when you subtract a negative with a negative you’re basically adding them together
