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

2. The probability that a car will come to a complete stop at a particular stop sign is 0.4. Assume that the next four cars
arrive at the stop sign are independent of one another. Find each of the following probabilities:
a) None of the four cars come to a complete stop?
Answers
Answer:
[tex]P(X = 0) = 0.1296 [/tex]
Step-by-step explanation:
This can be solved using the binomial distribution because the cars arriving at the stop are independent of each other. This means we will use:
[tex]P(X = x) = \binom{n}{x} p^{x} q^{n - x}[/tex]
Where p is the probability of success, q = 1 - p is the probability of failure and n is the number of cars sampled.
p = 0.4
q = 0.6
n = 4
Therefore,
[tex]P(X = 0) = \binom{4}{0} 0.4^{0} 0.6^{4}[/tex]
This is equal to
[tex]P(X = 0) = 1 \times 1 \times 0.1296 [/tex]
[tex]P(X = 0) = 0.1296 [/tex]

The weight of water in a person’s body varies directly as his/her body weight. The body of 170-lb person contains about 119-lb of water. How much water is in the body of a person who weighs 120-lb?
Answers
Answer:
119-50 pounds = 69 so 169 pounds -step explanation: blood= weight (k)
Step-by-step explanation:
y=kx
2
4.6 = 170k
finding the constant of variation
3
k= 0.02875
4
equation relates quarts of blood to weight
5
RESULT
4.6 = 170k
y= 0.02875x
y= 0.02875(175)= 5.03125
Answer:
Ww=84 lb
Step-by-step explanation:
Proportions
A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:
y=k.x
Where k is the constant of proportionality.
The value of k is obtained by using the values of a specific point.
The weight of water Ww in a person's body varies directly as their body weight Wb as follows:
Ww=k.Wb
We are given a 170-lb person contains 119 lb of water. Substituting:
119=k.170
Solving for k:
k=119/170=0.7
The function is:
[tex]Ww=0.7\cdot Wb[/tex]
To find how much water is in the body of a 120-lb person, we substitute Wb=120:
[tex]Ww=0.7\cdot 120[/tex]
Ww=84 lb
Find the sum of the interior angle measures of the green polygon,
Then sum of the interior angle measures is
Answers
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°

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.
Answers
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?
Answers
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.
