Answer:
a) Grade = 93, Standard score = 1.5
Grade = 62, Standard score = -1.6
b) Standard scores = 0.6, Grade = 84
Standard scores = 1.2, Grade = 90
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 78
Standard Deviation, σ = 10
Formula:

a) Grade = 93

Grade = 62

b) We have to find grades of student
Standard scores = 0.6

Grade = 84
Standard scores = 1.2

Grade = 90
Answer:
377/389
Step-by-step explanation:
Add all the values together:
12 + 352 + 25 = 389
352 visitors purchased one costume. 25 visitors purchased more than 1 costume. Add these values.

Put this value and the number of visitors to the site total together as a fraction
377/389
This fraction can't be simplified. This is the answer
Answer:
C) 2 ÷ 4 = 1/2
Step-by-step explanation:
Answer:
y= 4x+3
Step-by-step explanation:
To write your equation, solve for the slope.
(y2-y1)/ (x2-x1)
Find two coordinate points from the table.
(0,3) (1,7)
(7-3)/ (1-0)= 4
m=4
Use point-slope equation to find your equation.
(y-y1)=m(x-x1)
(y-3)=4(x-0)
y-3= 4x
y= 4x+3
