Answer:
-26
Step-by-step explanation:
Hello There!
For this problem all we have to do is plug in -5 into x and calculate the value
so..
-3|-5|+2(-5)-1
so first things first | | means absolute value
The absolute values of -5 is 5 so the equation would be
-3(5) + 2(-5) - 1
-3*5=-15
2*-5=-10
-15-10=-25
-25-1=-26
so the answer would be -26

Step-by-step explanation:
I assume you want the roots. Here we go:
Use the quadratic formula: 
.
The discriminant is 900 - 1008, or -108 (so we will need i, the complex number that means 
).
This means on the top you get 30 + 6isqrt3 and on the bottom you get 12.
So the fraction is 
Note: This is just one of the roots, I am sure you can find the second one!

Step-by-step explanation:
We know that the:
mean = 93.9
standard deviation = 3.12
In calculating how many standard deviation a number is away from the mean, we simply deduct the mean from the highest and lowest number in the set, then dividing it by the standard deviation. This is also known as getting the z score which has the following formula:
Z = (highest/lowest number - mean)/ standard deviation
For the highest number which is 99, Z = (99 - 93.9) / 3.12 = 1.6
For the lowest number which is 88, Z = (88 - 93.9) / 3.12 = -1.89
All the quiz grades fall within 2 standard deviations away from the mean.
