Answer:
0.8762 or 87.62%
Step-by-step explanation:
Since our mean is μ=14.3 and our standard deviation is σ=3.7. If we're trying to figure out what percentage is P(10 ≤ x ≤ 26) equal to we must first calculate our z values as such:
Our x value ranges from 10 to 26 therefore let x=10 and we obtain:
If we look at our z-table we find that the probability associated with a z value of -1.16 is 0.1230 meaning 12.30%.
Now let's calculate the z value when x = 26 and so:
Similarly, we use the z-table again and find that the probability associated with a z value of 3.16 is 0.9992 meaning 99.92%.
Now we want to find the probability in between 10 and 26 so we will now subtract the upper limit minus the lower limit in P(10 ≤ x ≤ 26) therefore:
0.9992 - 0.1230 = 0.8762
or 87.62%
Answer:
x=-23
Step-by-step explanation:
-3.8x-5.9x=223.1
-9.7x=223.1
x=223.1/-9.7
x=-23

Step-by-step explanation:
A cube's sides are all equal
Answer:
P = $240,000 – $196,000 = $44,000.
The expected value is a weighted average of each possible value weighted by its probability.
EV = ($44,000)(0.75) + ($–196,000)(0.25) = $–16,000.
The expect average profit is $–16,000.
The company should not make the product.

Nearest 1,000 = 24,062,000
Nearest 100,000= 24,100,000
Hope its correct :)
