First you got to subtract 100 from 50 than you have to divide 50 by 8 and then multiply by 3
First we can subtract the sales tax so we are just working with what's left: $17 - $0.92 = $16.08. Then we multiply the price of the sandwiches by 2 for the number Corey bought: 5.25 x 2 = $10.50. Then subtract that amount from what you have left: $16.08 - 10.50 = 5.58. Then, take that amount and divide it by three drinks: $5.58 / 3(drinks) = $1.86 per drink. I don't see the table so I hope this answers the question well enough!:)
Answer:
f(x)=1/4(5-x)²
Step-by-step explanation:
f(11)=1/4(5-11)²
1/4(-6)²
1/4(36)
=9
Answer:
See explanation below
Step-by-step explanation:
Since each time after the person gets off the scale, the reading is 2 lb the person's weight must be near the mean of
148-2, 151-2, 150-2, 152-2; that is to say, near the mean of 146, 149, 148, 150 = (146+149+148+150)/4 = 148.25
We could estimate the uncertainty as <em>the standard error SE
</em>
where
<em>s = standard deviation of the sample
</em>
<em>n = 4 sample size.
</em>
Computing s:
So, the uncertainty is 1.479/2 = 0.736
<em>It is not possible to estimate the bias, since it is the difference between the true weight and the mean, but we do not know the true weight.
