Answer:
In the picture above.
Step-by-step explanation:
First: I solved the right side to get y=93.
Second:calculate the triangle to get z=15.
Third: x=90.
Answer:
<u>Infinitely</u><u> </u><u>many</u><u> </u><u>solutions</u>
Step-by-step explanation:
There are 2 variables in this equation. Since, there are infinite many numbers, we can substitute them in x & y. This will lead to an <u>infinite</u><u> </u><u>number</u><u> </u><u>of</u><u> </u><u>solutions</u><u>.</u>
Answer:
300000
Step-by-step explanation:
An easy way to solve this is find 6x5 which is 30 and then add all of the 0s at the end from the equation which is 4 zeros
Answer:
0.0869
Step-by-step explanation:
The arc electronic company had an income of 90 million dollars last year.
Mean(μ) = 75 million dollars
Standard deviation (σ) = 11 million dollars
Probability that the randomly selected will earn more than arc did last year = Pr(x>90)
Using normal distribution,
Z = (x - μ) / σ
Z = (90 - 75) / 11
Z = 15/11
Z = 1.36
From the normal distribution table, 1.36 = 0.4131
Φ(z) = 0.4131
Recall that when Z is positive, Pr(x>a) = 0.5 - Φ(z)
= 0.5 - 0.4131
= 0.0869
