To find the cost per pound you simply divide the amount paid by the amount purchased
For Beef it would be:
$7.20 ÷ 2.0 = $3.60
For Pork it would be:
$8.10 ÷ 2.5 = $3.40
For Chicken it would be:
$9.80 ÷ 3.5 = $2.8
Answer: 8/145
Step-by-step explanation: Rewriting the table
Positive and Negative stand for the result of the test
Yes and No stand for having the disease
Positive | Negative | Total
<u>Yes </u><u> | 137 | 8 | 145</u>
<u>No </u><u> | 16 | 139 | 155</u>
<u>Total</u><u> | 153 | 147 | 300</u>
<u />
probability of getting someone who tests negative, given that he or she had the disease.
P(Negative | Yes) = <u>P(Negative ∩ Yes)</u> = <u> 8 </u>
P(Yes) 145
<u />
Answer:
a) P(X≥143)=0
b) This contradicts the study as getting a sample with this proportion is almost impossible (if the proportion of 68% is true).
Step-by-step explanation:
If we use the normal approximation to the binomial distribution we have the following parameters (mean and standard deviation):
Then, we can calculate the probability of X being equal or more than 143 using the z-score:
This contradicts the study as getting a sample with this proportion is almost impossible (if the proportion of 68% is true).
Answer:
(6,8)
Step-by-step explanation:
The rule for 90 degree rotation is (x,y)=(-y,x)
So the answer is (6,8)
Answer:
<h2><em><u>
The cube is the answer.</u></em></h2>
Step-by-step explanation:
The rectangular prism has a volume of 112.
The second rectangular prism has a volume of 81.
THe third rectangular prism has a volume of 108.
<h2><em><u>
The cube has a volume of 125.</u></em></h2>
Hope it helps!
