The correct answer is 6/7.
Answer:
$15.40
Step-by-step explanation:
At a given hourly rate, the pay is proportional to the hours spent earning it. So, we have ...
pay/hours = $17.92/3.2 = (mowing pay) / 2.75
Multiply by 2.75 to get ...
(mowing pay) = $17.92·(2.75/3.2) = $15.40
Hilary earned $15.40 mowing lawns.
Answer:
H0 : mu1 = mu2
Ha : mu1 ≠ mu2
Which means
Null hypothesis H0; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is the same/equal
Alternative hypothesis Ha; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is different (not equal)
Step-by-step explanation:
The null hypothesis (H0) tries to show that no significant variation exists between variables or that a single variable is no different than its mean(i.e it tries to prove that the old theory is true). While an alternative Hypothesis (Ha) attempt to prove that a new theory is true rather than the old one. That a variable is significantly different from the mean.
Therefore, for the case above;
H0 : mu1 = mu2
Ha : mu1 ≠ mu2
Which means
Null hypothesis H0; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is the same/equal
Alternative hypothesis Ha; the true mean price when buying from a friend mu1 and the true mean price when buying from a stranger mu2 is different (not equal)
They did not use the distributive property correctly in step one the correct answer is Step 2: 9y-24=10+3y
Good luck mate :P
Answer:
Step-by-step explanation:
<u>Use the formula:</u>
<u>Substitute the values and find P:</u>
- P = 2(30 +75) = 2(105) = 210
