Answer:
The value for the test statistics = 3.48
Step-by-step explanation:
Given that:
population mean 
= 75
sample size n = 25
sample mean 
= 78.48
standard deviation = 5
The value for the test statistics can be computed by using the formula:
z = 3.48
The value for the test statistics = 3.48
Answer:
5,525
Step-by-step explanation:
You have 1,045 students in Roosevelt.
and for Truman its 5 times as much
times= multiply
so you multiply 1,o45 by 5
should look like this:
1,045 *5
answer: 5,525
A= 1/2 b= -3 c= -2
that's it.
H(x) = 125^x
Domain: all the real numbers (from negative infinity to infinity)
Range: all the positive real numbers.
As x decreases 125^x decreases approaching to 0. The function will never reach the value 0 but will approximate to it as x goes to negative infinity. The rate of decreasing gets lower and lower, with a limit of zero, when x becomes more and more negative.
As x increases 125^x increases indefinetely and at an increasing rate. That means that the increase is accelerated (the bigger the value of x the bigger the rate of increasing).
Answer:
equation: a/.5b=h
h=9
Step-by-step explanation:
a=1/2bh
divide both sides by 1/2b to get h alone
a/.5b=h
a/.5b=h
54/0.5(12)=h
54/6=h
9=h
