Step 1. Find the Greatest Common Factor (GCF)
GCF = 3m^2
Step 2. Factor out the GCF <span>(Write the GCF first. Then, in parentheses, divide each term by the GCF.)
3m^2(15m^2/3m^2 + -12m^3/3m^2)
Step 3. Simplify each term in parentheses
3m^2(5 - 4m)</span>

<span>Simplifying 15m2 + -12m3 = 0 Solving 15m2 + -12m3 = 0

Solving for variable 'm'. Factor out the Greatest Common

Factor (GCF), '3m2'. 3m2(5 + -4m) = 0 the factor is 3.

Factor completely 3x2 - 21.

VMariaS [17]

3x² - 21

Factor 3 from both terms:

3 (x² - 7)

To me, that's as far as you should need to go. But if you want to get
completely carried away, you could go one step further, since you have
the difference of two squares:

3 (x + √7) (x - √7)

Of course, there's no end now, because the last binomial could be
considered another difference of two squares, so you'd have to
factor that too:

3 (x + √7) (√x + ⁴√7) (√x - ⁴√7)

but to me, this would be nonsense.

Answer:

Step-by-step explanation:

51 ÷ 7.2 is about 7.08 continued but you can't make .08 of a braclet so it's just 7

patriot [66]

Answer:

See below.

Step-by-step explanation:

6.) (5)/6 ≤ 1 (Yes)

7.) 1.4(11) > 16

15.4 > 16 (No)

8.) 11.1 + 9.8 ≥ 21.01

20.9 ≥ 21.01 (No)

9.) 2.5 < (90)/30

2.5 < 3 (Yes)

10.) 1/2 > 3(1/6)

1/2 > 1/2 (No)

11.) 2.16 ≥ 3(0.6) - 0.5

2.16 ≥ 1.8 - 0.5

2.16 ≥ 1.3 (Yes)

12.) x < 2 (x is less than 2.)

13.) x ≥ -1 (x is greater than or equal to -1.)

Suppose that the quarterly sales levels among health care information systems companies are approximately normally distributed w

cupoosta [38]

Answer:

The cutoff sales level is 10.7436 millions of dollars

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = \frac{X - \mu}{\sigma}$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

In this problem, we have that:

$\mu = 12, \sigma = 1.2$
