Answer:
0.002
Step-by-step explanation:
We need to estimate the standard error of the mean, so we can use it as a standard deviation of the sample of 50 males.
Standard error of the mean = standard deviation/√n
Standard error of the mean = 32/√50 = 4.52
Now we can use this Standard error of the mean to estimate z as follows:
Z = (x – mean)/standard deviation
Z = (190-177)/4.52
Z = 2.87
Using a Z table we can find probability that mean is under 190
P (z<190)= 0.998
For the probability that the mean exceed 190 lbs we substract from 1
P(z>190) = 1 - 0.998 = 0.002
Originally the ratio is 5:3, but we can make this ration 5x:3x because its equal. By doing so, we know that 5x+3x=32.
Now just solve the equation:
5x+3x=32
8x=32
x=4.
Now insert x into ratio.
Since she needs 3x of guava juice, she needs 3*4 fl oz of guava juice. She need 12 fl oz of guava juice.
Answer:
12 FL OZ of guava juice.
Answer:
option 4
Step-by-step explanation:
fog(x)=(x-5)²+4
=x²-10x+25+4
fog(x)=x²-10x+29
Answer:
y = -1/3x + 5/3
Step-by-step explanation:
First solve the equation. Simply put it is y = -1/3x + 5/9.
So, we have our slope which is -1/3. Now just plug it in.
y - y1 = m(x - x1)
y - 2 = -1/3(x - (-1))
Distribute.
y - 2 = -1/3x - 1/3
Add 2 to both sides
you get y=-1/3x + 5/3
15x + 4 would be the algebraic expression
