There are some numbers missing in your table. We think the values are supposed to be the ones shown in the attachment.
The number of people that are older than 35 and have a hemoglobin level between 9 and 11 is 46. The total number of people older than 35 is 162, so the proportion of people older than 35 with the hemoglobin level of interest is ...
... 46/162 ≈ 0.284
The appropriate choice is B. 0.284.
_____
<em>Here's how you get there with the formula for conditional probability.</em>
P(9-11 | >35) = P(9-11 & >35)/P(>35) . . . . conditional probability formula
P(9-11 | >35) = (46/429) / (162/429) = 46/162

hope this might be useful
Answer:
True
Step-by-step explanation:
64x³ + 125
64x³ = (4x)³ ← a perfect cube
125 = 5³ ← a perfect cube
Thus 64x³ + 125 ← is a sum of cubes
Answer:
$599
Step-by-step explanation:
Given: Discount- 40% off on original price.
Gift card= $25
Total cost before taxes is $334.40
Lets assume the original price be "x".
We know there is 40% on original price and Perry uses $25 gift card.
Remember; Total cost= 
Now, finding the original price of Iphone.
⇒ 
⇒ 
Adding both side by 25
⇒
⇒
Dividing both side by 0.60
⇒ 
∴ 
Hence, the original price of iphone is $599
To find the height, you would do the area divided by the base, or in this case,187.5 / 25 which equals 7.5 inches. Hope this helped!
