Answer:
353.35 is the answer of this question
So the equation is x + 2x + 5= 29
Here are the steps -5 -5
-----------------------
3x = 24
Divide both sides by 3 so you get
x = 8
Then look back at the question, the second number has to be twice that number plus 5
So the 1st number is 8 The second # is 2(8)+5= 21
Answer:
Option 1 is correct.
Step-by-step explanation:
Given angle
. we have to find the quadrant and the reference angle.
Angle given is
Hence, the angle is 110° lies in second quadrant.
Now reference angle, the smallest angle that you can make from the terminal side of an angle with x-axis.
which is 
Hence, option 1 is correct.
Answer:
The correct answer is
(0.0128, 0.0532)
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of
, and a confidence interval
, we have the following confidence interval of proportions.

In which
Z is the zscore that has a pvalue of 
For this problem, we have that:
In a random sample of 300 circuits, 10 are defective. This means that
and 
Calculate a 95% two-sided confidence interval on the fraction of defective circuits produced by this particular tool.
So
= 0.05, z is the value of Z that has a pvalue of
, so
.
The lower limit of this interval is:

The upper limit of this interval is:

The correct answer is
(0.0128, 0.0532)
Answer:
b(ab-1`)
Step-by-step explanation:
Just remove "b" from both terms and place it outside the parentheses.
