Mathematics
1 answer:
Margaret [11]3 years ago
6 0

If you want to multiply a decimal by a whole number, just ignore the decimal point and multiply like normal! Then, bring the decimal point back for the answer. for example 2×0.2

first multiply 2*2=4

and then place the decimal we have one value after decimal so the answer is 0.4

Hillary earned $17.92 weeding gardens for 3.2 hours she was paid the same hourly rate to mow lawns Hillary mowed lawns for 2.75
Sindrei [870]

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.

We want to use this information to determine if there is an effect of friendship. In other words, is the mean price when buying
saw5 [17]

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)
