The answer for the question shown above is: <span>B. Both powers should be in the dominator with positive exponent.
The explanation is shown below:
1. You have the following expression given in the problem above:
x⁻3y⁻9
2. The negative exponents indicates that </span>x⁻3y⁻9 should be in the denominator with positive exponents. Therefore, you have:
x⁻3y⁻9=1/x^3y^9
Answer: 8.4
Step-by-step explanation:
You would convert 25 into a decimal 0.25 and then you would multiply it by 34 which would get you 8.4 hope this helped brutherr

Answer:
It flew 1,365 miles
Step-by-step explanation:
Just multiply the speed in mph by the time in hours so 455 * 3
Given:
μ = $3.26 million, averaged salary
σ = $1.2 million, standard deviation
n = 100, sample size.
Let x = random test value
We want to determine P(x>4).
Calculate z-score.
z = (x - μ)/ (σ/√n) = (4 - 3.26)/(1.2/10) = 6.1667
From standard tables,
P(z<6.1667) = 1
The area under the distribution curve = 1.
Therefore
P(z>6.1667) = 1 - P(z<=6.1667) = 1 - 1 = 0
Answer: The probability is 0.
