X= 5/8 or in decimal form it is x= 0.625
Answer: B. This student's test grade was 2.4 standard deviations above the mean test grade.
====================================================
Explanation:
The z score tells us how far away the raw score is from the mean. This distance is in terms of standard deviations.
- z = 1 means we're 1 standard deviation above the mean
- z = 2 means we're 2 standard deviations above the mean
and so on.
Negative z scores indicate the raw score is below the mean.
- z = -1 means we're 1 standard deviation below the mean
- z = -2 means we're 2 standard deviations below the mean
and so on. So that's why z = 2.4 indicates the students test grade was 2.4 standard deviations above the mean.
Answer:
your question is not correct can you send me a pic
First, find where they are equal
because g(x) grows at a faster rate so it will somwehre start to go past f(x)
solve for x such that f(x)=g(x)
so
3x+30=x²+20
minus (3x+30) both sides
0=x²-3x-10
facotr
what 2 numbers multiply to get -10 and add to get -3?
-5 and 2
0=(x-5)(x+2)
set each to zero
0=x-5
5=x
0=x+2
-2=x
at x=5 and -2
test points between them
at x=-3, g(x)>f(x)
at x=0, f(x)>g(x)
at x=6, g(x)>f(x)
so g(x)>f(x) when x<-2 or x>5
so I think the teacher is looking for that point when g(x)<f(x) then g(x)>f(x)
so that would be at x=5
Answer:
D. All of these
Step-by-step explanation:
In order to construct a circle, you have to find the chord of the circle, the center of the circle, and the radius. These all need to be known if you want to create a circle. You must have all the information, or you will not be able to create your circle. The answer is D. all of these.
