Answer:
Step-by-step explanation:
Replacing X with -3 ves you -2(-3) + 5 > 13. -2(-3) is 10 + 5 > 13. 10 + 5 gives you 15, which is greater than 13.

Step-by-step explanation:
Previous concepts
A confidence interval is "a range of values that’s likely to include a population value with a certain degree of confidence. It is often expressed a % whereby a population means lies between an upper and lower interval".
The margin of error is the range of values below and above the sample statistic in a confidence interval.
Normal distribution, is a "probability distribution that is symmetric about the mean, showing that data near the mean are more frequent in occurrence than data far from the mean".
sample size 1
sample size 2
sample mean for group 1
sample mean for group 2
sample deviation for group 1
sample deviation for group 2
Solution to the problem
For this case the confidence interval is given by:
And the degrees of freedom are given by:
We want a 95% of confidence o then the significance level is 1-0.95 =0.05 and 
if we find a critical value in the t distribution with 36 degrees of freedom we got:
And replacing we got:
Answer:
you need a d/protector to do this

Answer:
ok, so two to the 19th power is 524,288, 2 to the 5th power is 32. 524,228 x 32=16,775,296.
2 to the 12th power is 4096, 3 to the 3rd power is 8, 4096 x 8=32,768.
16,775,296/32,768
after that just simplify.
hopefully my answ helps, i think i did it correctly, my brain is ded
Answer:
36
Step-by-step explanation:
consecutive even numbers are 2,4, 6...
Let the smallest of the 3 numbers be x.
2nd number= x+2
3rd number
=x+2+2
= x+4
sum of the 3 numbers= x +x+2 +x+4
114= 3x+6
3x= 114 -6 (-3 on both sides)
3x= 108 (simplify)
x= 108 ÷3
x= 36
Thus, the smallest number is 36.
Let's check!
36+38+40= 114 ✓
