On a test that has a normal distribution, a score of 60 falls two standard deviations above the mean, and a score of 42 falls on
Sergeu [11.5K]

Answer:

48

Step-by-step explanation:

Given that:

A  \ score  \ of \  60  \ falls \  two  \ standard   \ deviations \  above \  the \ mean \\ \\ A \  score \ of \ 42  \ falls \  one  \ standard  \ deviation \ below  \ the \ m ean

The interval for score = 60 - 42 = 18

If we divide it by the 3 standard deviations; the interval result into

= 18/3

= 6

So, the standard deviation is 6, and the mean = 42 + 6

= 48

What Is the y-intercept of the two points that cross through (8,1) and (-3,1)?
kramer

Answer:

(0,1)

Step-by-step explanation:

The line made by these two points is perfectly horizontal since the value of y in both points is the same. When the y value is the same in all given points, that number is also the y-intercept and the line doesn't cross the x axis.

(The opposite applies as well: If the x value is the same in all given points, that number is also the x-intercept and the line doesn't cross the y axis. In that case, that means the line is vertical)

If f(x) varies directly with x and f(x) = 4 when x = 12, then what is the value of f(x) when x = 60?
ANTONII [103]
ANSWER

f(60)=3\times60=180

EXPLANATION
We were given that
f(x)
varies directly as
x.

We can write this mathematically as,

f(x) \propto \: x.

This implies that,

f(x) = kx
where k is the constant of variation.

f(4)=4k

This implies that,

4k=12

k = 3

The equation becomes

f(x)=3x

When x=60

f(60)=3\times60=180
