Answer:
$2600
Step-by-step explanation:
Given that:
the employee earns $50,000 in a year
The amount of money on wages paid by the employee towards social security = 5.2% of their gross wage
= [tex]\dfrac{ 5.2 \times 50000}{100}[/tex]
= $2600
if an employee makes $50,000 in the year, he will pay $2600 towards social security.
The other employees that paid 7.3% of their gross wages will not be regarded since they're paying it from their own fund.
Residents of the town of Maple Grove who are connected to the municipal water supply are billed a fixed amount monthly plus a charge for each cubic foot of water used. A household using 1500 cubic feet was billed $80, while one using 2100 cubic feet was billed $92. Write an equation for the total cost of a resident's water as a function of cubic feet of water used.
Answer:
A = 50 + 0.02x
Step-by-step explanation:
Let the fixed amount be m
Let the charge for each cubic ft used be c
Let the amount of cubic ft of water used be x.
Let the total cost per month be A
Now, for the first household, they used 1500 cubic feet in a month and were billed $80.
This means, x = 1500 ft³ and A = $80
Since, we are told they are charged a fixed amount plus a fee per cubic ft consumed. We can say that;
m + cx = A
Thus,
m + 1500c = 80 - - - - (eq1)
For 2nd household:
They used 2100 cubic feet was billed $92.
Thus;
m + 2100c = 92 - - - - (eq 2)
Let's subtract eq1 from eq 2 to get;
2100c - 1500c = 92 - 80
600c = 12
c = 12/600
c = 0.02
Putting 0.02 for C in eq1 gives;
m + 1500(0.02) = 80
m + 30 = 80
m = 80 - 30
m = 50
From m + cx = A, we can say that;
50 + 0.02x = A

Answer:
7 + 9 = 16
Step-by-step explanation:
The commutative law states that a + b = b + a and ab = ba.
This means that 9 + 7 = 7 + 9.
Therefore, we can rewrite the equation as 7 + 9 = 16.
The five number summary of a dataset was found to be: 45, 46, 51, 60, 66
An observation is considered an outlier if it is below:____________.
An observation is considered an outlier if it is above:____________.
Answer/Step-by-step explanation:
Given the five summary of a data set:
45 - min
46 - Q1
51 - Median
60 - Q3
66 - Max
Thus, any number less than [tex] Q_1 - (1.5*IQR) [/tex], or any number that is greater than [tex] Q_3 + (1.5*IQR) [/tex] would be considered an outlier.
The IQR of the data set = Q3 - Q1 = 60 - 46 = 14
Thus,
[tex] Q_1 - (1.5*IQR) = 46 - (1.5*14) = 46 - 21 = 25 [/tex]
Therefore, an observation is considered an outlier if it is below: 25.
[tex] Q_3 + (1.5*IQR) = 60 + (1.5*14) = 60 + 21 = 81 [/tex]
Therefore, an observation is considered an outlier if it is above: 81.

A dot-com company’s CEO is worried that the employees feel over-worked. She waits till 7 p.m. one night and proceeds to briefly interview each employee still there to see whether they feel she is overworking them. What problems are there with this approach?
Answer:
Time wastage and not formal enough
Step-by-step explanation:
He didn't have to wait till that time to ask the the question, besides keeping them there will cause uneasiness between the workers because it's already late.
Another point is that some people might not decided to give him the reply face to face, as they night sound rude or something more than that.
A more formal approach and less time consuming and less stressful method like may be filling of forms, papers , or complaint letters should be used instead.
Find the relative extrema of the function, if they exist. Also, state the intervals where the function is increasing or decreasing. g
Answer:
The question is not complete. I will explain relative extrema and how to calculate it.
Step-by-step explanation:
The singular of extrema is extremum and it is simply used to describe a value that is a minimum or a maximum of all function values.
A function will have relative extrema (relative maximum or relative minimum) at points in which it changes from decreasing to increasing, or vice versa.
So if f(y) is a function of y
Function f(d) will be is a relative maximum of f(y),if there exists an interval (a, b) containing d
such that for all y in (a, b) , f(y) ≤ f(d)
Function f(d) will also be a relative minimum of f(y),if there exists an interval (a, b) containing d
such that for all y in (a, b) , f(y) ≥ f(d)
Kindly note that If f(d) is a relative extrema of f(y), then the relative extrema occurs at y = d.
For the local extrema of a critical point to be determined, the function must go from increasing, that means positive [tex]f^{'}[/tex], to decreasing, that means negative [tex]f^{'}[/tex], or vice versa, around that point.
[tex]f^{'}[/tex] is determined by finding the first derivative of the function f(y). The relative extrema will therefore allows us to check for any sign changes of f′ around the function's critical points.
you put $500 in your bank account. With a interest rate of 5%, how long will it take the account to reach $600?
Answer:
4 years hope this helps
Step-by-step explanation:
Answer:
4 Years
Step-by-step explanation:
t = I/Pr
Note the 600 is the total amount in the account.
Therefore Interest, I = 600 - 500 = 100.
t = 100 / (500 * 5%)

In a right triangle, the side opposite angle has length 4.84 meters and the hypotenuse has length 7.01 meters. What is the sine of the angle?
Answer:
0.69
Step-by-step explanation:
Let θ be the angle.
The following data were obtained from the question:
Opposite = 4.84 m
Hypothenus = 7.01 m
Sine θ =?
The sine of the angle θ can be obtained as follow:
Sine θ = Opposite /Hypothenus
Sine θ = 4.84/7.01
Sine θ = 0.69
Therefore, the sine of the angle is 0.69
Solve the equation below and find the variation constant, k .Find y when x = 7 and z=5, if y varies jointly as x and 2, and y= 14 and x = 4 when z= 3
Variation Constant: k = 7/6
y = 245/6 when x = 7 and z = 5
====================================
Explanation:
"y varies jointly as x and z" means that y = kxz
We have (x,y,z) = (4,14,3) as one triple, so,
y = kxz
14 = k*4*3
14 = 12k
12k = 14
k = 14/12
k = 7/6 is the variation constant
The equation goes from y = kxz to y = (7/6)xz
----------------
Plug in x = 7 and z = 5 to find y
y = (7/6)xz
y = (7/6)*7*5
y = (7/6)*(7/1)*(5/1)
y = (7*7*5)/(6*1*1)
y = 245/6

Which data set could be represented by the box plot shown below?
Answer/Step-by-step explanation:
The answer choices to this question showing possible set of data that could be represented by the box plot is missing.
However, here's how to find out which data set could be represented by the box plot.
The box plot given displays of a five-number summary consisting of,
1. The minimum value = 24
2. The second quartile = 27
3. The median value = 31
4. The third quartile = 33
5. The maximum value = 34
With these values known, you can easily find out which data set the box plot represents. Thus, the data set that has a min value of 24, max value of 34, and a median of 31 should be the data set that the box plot is representing. If you have more than one options having these same three values, then proceed to find the second and third quarter to determine which one is the most appropriate.

A plant is already 15 centimeters tall, and it will grow one centimeter every month. Let H be the plant's height (in centimeters) after M months. Write an equation relating H to M. Then graph your equation using the axes
Answer:
H = 15 + M
Step-by-step explanation:
The plant starts out at 15 cm tall, therefore the y intercept is (0,15) and there is an x intercept but it isn't valid in this case as a plant cannot grow backwards (I assume). The domain would be (0,infinity) and the range would be (15,infinity).

FIND THE VALUE OF X2 FOR 20 DEGREES OF FREEDOM AND AN AREA OF .010 IN THE RIGHT TAIL OF THE CHI SQUARE
Answer:
The critical value of chi-square for 20 degrees of freedom and 0.01 level of significance is 37.57.
Step-by-step explanation:
We have to find the value of chi-square for 20 degrees of freedom an area of 0.01 in the right tail of the chi-square.
As we know that in the chi-square table; there is one vertical column represented by 'P' (the level of significance and one horizontal column represented by '[tex]\nu[/tex]' which is degrees of freedom.
Here, the degrees of freedom given to us is 20.
and the level of significance is 0.01 or 1% for the right tail of chi-square.
By looking at the chi-square table, the critical value of chi-square for 20 degrees of freedom and 0.01 level of significance is 37.57.
