Answer: m = 7 or -2
Step-by-step explanation:
Quadratic Formula!
Polynomial Form:
So in this example a: 1 b: -5 c: -14
You get:
m = 7 or -2
Check by plugging a value back in for m

The better statistics which can be used to compare the given distributions are mean and standard deviation.
<h3>What is a z-core?</h3>A z-core is also referred to as a standard score and it can be defined as a statistical measure of the distance between a data point (raw score) and the mean, especially when standard deviation units are used.
In Mathematics, z-scores can either be negative or positive and it is generally calculated by using this formula:
<u>Where:</u>
- x is the observed data or sample mean.
- u is the mean.
is the standard deviation.
In conclusion, the better statistics which can be used to compare the given distributions are mean and standard deviation.

<h2>The answer isStep-by-step explanation:
Let the building contractor bought 1000 cement in total.
70% of 1000 = 700 cements were from A and (1000 - 700) = 300 cements were from B.
The number of undamaged bag from A was 95% of 700 = and the number of undamaged bags from B was 70% of 300 =
.
Total undamaged bags were (665 + 210) = 870.
The probability that an undamaged bag is from A is .
