A lay office assistance gets 236.39 every two weeks. How much will they make in a year? Round to the nearest cent
Answer:
Step-by-step explanation:round the number then x it by 12
Answer:
$5673.36
Step-by-step explanation:
4 weeks in a month
12 months in a year
Therefore, they get paid twice in a month.
236.39 * 2(twice in a month) = 472.78 per month
Take this and times it by 12 since there are 12 months in a year.
472.78*12 = 5673.36

Ten samples of coal from a Northern Appalachian source had an average mercury content of 0.242 ppm with a standard deviation of 0.04 ppm. Find a 95% confidence interval for the mean mercury content of coal from this source. Round the answers to four decimal places.
Answer:
0.2172<x<0.2668
Step-by-step explanation:
The formula for calculating the confidence interval is expressed as;
CI = xbar ± (z*s/√n)
xbar is the average = 0.242ppm
z is the z score at 95% confidence = 1.96.
s is the standard deviation = 0.04pm
n is the sample size = 10
substitute the values into the formula;
CI = xbar ± (z*s/√n)
CI = 0.242 ± (1.96*0.04/√10)
CI = 0.242 ± (1.96*(0.04/3.1623))
CI = 0.242 ± (1.96*(0.01265))
CI = 0.242 ± (0.02479)
CI = (0.242-0.02479, 0.242+0.02479)
CI = (0.2172, 0.2668)
Hence a 95% confidence interval for the mean mercury content of coal from this source is 0.2172<x<0.2668.

Alpha Pharmaceuticals is manufacturing a new antibiotic. The amount of active substance in each pill is normally distributed with a mean of 20 mg and a standard deviation of 2.5 mg. What is the probability of a pill having more than 24.125 mg active substance?
Answer:
The probability of a pill having more than 24.125 mg active substance is 0.0495.
Step-by-step explanation:
Let X denote the amount of active substance in each pill.
It is provided that,[tex]X\sim N(20,\ 2.5^{2})[/tex]
Compute the probability of a pill having more than 24.125 mg active substance as follows:
[tex]P(X>24.125)=P(\frac{X-\mu}{\sigma}>\frac{24.125-20}{2.5})[/tex]
[tex]=P(Z>1.65)\\\\=1-P(Z<1.65)\\\\=1-0.95053\\\\=0.04947\\\\\approx 0.0495[/tex]
Thus, the probability of a pill having more than 24.125 mg active substance is 0.0495.
Find the sum of the interior angle measures of the green polygon,
Then sum of the interior angle measures is
Answer:
The sum of interior angles of given polygon is 900°
Step-by-step explanation:
A regular polygon is a n-sided figure with n sides and the length of all sides is same.
In the diagram, we have a polygon with 7 sides.
The formula given is used to calculate the sum of interior angles of a polygon
[tex]Sum\ of\ interior\ angles = (n-2)*180[/tex]
Here n is the number of sides of polygon
In the given polygon
n = 7
So,
[tex]Sum = (7-2)*180 = 5*180 = 900[/tex]
Hence,
The sum of interior angles of given polygon is 900°

What is congruence?Triangle congruence: If all three corresponding sides and all three corresponding angles are equal in size, two triangles are said to be congruent. Slide, twist, flip, and turn these triangles to create a similar appearance. They are in alignment with one another when moved. "≅" is the congruence symbol.
How to solve it?Use the following figure to understand the answer.
The Proof is
1. KM=KO=5 (GIven)
2. MN=3 (Given)
3. KN=KM+MN=8 (because the lengths are equal to the sum of their parts.)
4. KL=8 (Given)
5. KL=KN (from 3,4 substitution)
6. NO=ML=9 (Given)
7. ΔKLM=ΔKNO the congruence criterion used is SSS congruence.

When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. ∠1 is the angle of depression from point Q to R.
What is an angle?When two straight lines or rays intersect at a shared endpoint, an angle is generated. An angle's vertex is the common point of contact. Angle is derived from the Latin word angulus, which means "corner."
