The answer for "-2a + 3b" is 5.
To solve this equation, you must first find "a" and "b". A^3 times B^2 = 72. In this case, a = 2 (2*2*2 = 8) and b = 3 (3*3 = 9) since their outcomes multiplied together equal 72.
Now you fill in for "a" and "b". "-2*2 + 3*3" before adding you do all the multiplying, which leaves "-4 + 9". Combining like terms gives you 5.
I hope this helps!!

Step-by-step explanation:
Is the Square Root of 225 Rational or Irrational? 225 can be expressed as the ratio of two integers. As 225 can be expressed as 225 = 225/1. Thus 225 is rational.
Answer:
(D) If the null hypothesis is true, the probability of observing a mean reduction of at least 13 ppm is 0.095
Step-by-step explanation:
The P-value represent the probability of a sample like the one we are testing, given that the null hypothesis is true. In other words, the probablities of getting that sample by pure chance.
That is why if the P-value is smaller than the significance level, it is considered evidence that the null hypothesis is not true.
In this test, the test claim is that new process for producing yarn reduces the mean amount of volatile organic compounds (VOCs) emitted by carpet.
As the reduction is expressed as a positive number, this is an upper-tail test (μ>13 ppm).
Then, the P-value represents then the probability of getting a sample with mean reduction of VOCs of 13 ppm or more, given that the null hypothesis is true.
