All you have to do is divide the numerator and the denominator by 3 and you get your answer which is 1/6
Answer:
We want to verify if the true proportion of the alumni provide monetary contributions is higher than 0.15 (Alternative hypothesis), the system of hypothesis are.:
Null hypothesis:
Alternative hypothesis:
And the best answer for this case would be:
Ha: p > 0.15
Step-by-step explanation:
Information given
n=250 represent the random sample taken
X=40 represent the number of people on the alumni mailing list
estimated proportion of people on the alumni mailing list
is the value to verify
z would represent the statistic
represent the p value
Hypothesis to test

Equivalent Expressions are expression that have the same value on both side of the equal sign.
Expression 1:
First simplify both sides of the expression. One of them are already fully simplified.
8x-4y=4(-y+2x)
8x- 4y=-4y+8x
This expression IS an equivalent expression.
Expression 2:
Do the same as in expression one (we will be simplifying all of the expressions).
8x+4y=4(2x+y)
8x+4y=8x+4y
This expression IS an equivalent expression.
Expression 3:
4x-8y=4(-x+2y)
4x-8y=-4x+8y
This expression IS NOT an equivalent expression.
Expression 4:
4x+8y=4(x+2y)
4x+8y=4x+8y
This expression IS an equivalent expression.
Expression 5:
4x+8y=4(8xy)
4x+8y=32xy
This expression IS NOT an equivalent expression.
Answer:
40
Step-by-step explanation:
<h2><u>Ratios </u></h2>
16 is to 10 as what number is to 25
this makes use of ratios
16 : 10
x : 25
hence we can make use of cross multiplication
10x = 16 * 25
10x = 400
<u>x = 40</u>
<u />
<h3><u>the number is 40</u></h3>
Answer:
A
Step-by-step explanation:
plug it in
(-3)^2+(4)^2=9+16=25
