X is equal 3. to do this, you do reverse of order of operations. So this means that you would to the 'times 2' first by dividing 4 by 2 to make it 2. then, in the parenthesis, since there is a 'minus 1', therefore you are going to add 1+2 which equals three. <span />
Answer:
hello your question is incomplete attached below is the complete question
answer :
H0 : <em> u </em>= 21.62 ( Null hypothesis )
H1 : <em> u</em> = 21.62 ( alternative hypothesis )
Step-by-step explanation:
Formulating hypothesis that can be used to determine whether the population mean rate at 5 CCF of residential water discharged by U.S public utilities differs from $21.62
H0 : <em> u </em>= 21.62 ( Null hypothesis )
H1 : <em> u</em> = 21.62 ( alternative hypothesis )
Answer:
0.0057
Step-by-step explanation:
- Narrow it down.
- The point P is between 5 * 10^-3 and and 6*10^-3
- When you go to the bottom line, P is on the 7th division from the left.
- Going from left to right increases P
- P is on a line that goes between 5 and 6. Each division is 1/10. So P is in the tenth place.
- One of the answers is 5.7 * 10^-3
- The other answer is .0057
- I really don't know which one to choose because we are given no direction. As a programmer, 0.0057 would be easier to program. I would choose it.
- If it is not correct, then 5.7 * 10^-3 is the answer.
Answer:
b 125
Step-by-step explanation:
first you know that you have 2 and 5 as similar numbers you both square them so that they become a ratio of area which is 4/25 after you do 4/25=20/x and you do cross multiply then you find 125. hope that helped understand.
Answer:
x = - 6 ± 
Step-by-step explanation:
Given
x² + 12x = 1
To complete the square
add ( half the coefficient of the x- term )² to both sides
x² + 2(6)x + 36 = 1 + 36
(x + 6)² = 37 ( take the square root of both sides )
x + 6 = ± ( subtract 6 from both sides )
x = - 6 ± ← exact solutions
