Answer:
$ 78.68
Step-by-step explanation:
The following data were obtained from the question:
Pay >>>>>>>>>> Frequency
40 – 59 >>>>>> 15
60 – 79 >>>>>> 58
80 – 99 >>>>>> 27
100 – 119 >>>>> 22
Mean pay =?
Next, we shall determine the class pay. This can be obtained by adding the pay together and dividing by 2 as shown below:
L => is the lower pay interval
U => is the upper pay interval
Pay >>>>>>>>>> Class pay [(L+U)/2)]
40 – 59 >>>>>> 49.5
60 – 79 >>>>>> 69.5
80 – 99 >>>>>> 89.5
100 – 119 >>>>> 109.5
Thus, the table becomes
Pay >>>>>> Class pay >> Frequency
40 – 59 >> 49.5 >>>>>>> 15
60 – 79 >> 69.5 >>>>>>> 58
80 – 99 >> 89.5 >>>>>>> 27
100 – 119 > 109.5 >>>>>> 22
The mean pay can be obtained as follow:
Summation of class pay and frequency (ΣCF) = (49.5×15) + (69.5×58) + (89.5×27) + (109.5×22)
= 742.5 + 4031 + 2416.5 + 2409
= 9599
Summation of frequency (ΣF) = 15 + 58 + 27 + 22
= 122
Mean pay = ΣCF / ΣF
ΣCF = 9599
ΣF = 122
Mean pay = 9599 / 122
Mean pay = $ 78.68
Therefore, the mean pay is $ 78.68

Find the value of x that makes N the Incenter of the triangle
Answer:
um im not 100% but i think 47
Step-by-step explanation:
The value of x for the given triangle is found to be 6.
What is Pythagoras theorem?Pythagoras theorem states that in a right angled triangle, the sum of the squares of the perpendicular and base is equal to the square of the hypotenuse. It can be written as h² = p² + b².
Given triangle has N as the incentre.
Which implies that NJ = NL= NK.
Now, apply Pythagoras theorem in ΔANK to obtain,
AN² = AK²+ NK²
=> 37² = 35² + NK²
=> NK²= 37²- 35²
=> NK²= 144
=> NK = 12
Then, As per the question it can be written as,
2x = 12
=> x = 6
Hence, the value of x for the point N to be the incentre is 6.

The citizens of a city were asked to choose their favorite type of pet. The circle graph shows how the citizens answered. If 95000 citizens answered the question, how many chose Cat?
Answer:
21% chose cats
Step-by-step explanation:
On a certain hot summer day, 738 people used the public swimming pool.The daily prices are 1.50 for children and 2.00 for adults.The receipts for admission totaled 1306.00 .How many children and how many adults swam at the public pool that day?
Answer:
A = 340 adult.
C = 398 children.
Step-by-step explanation:
Let the number of children be C
Let the number of adults be A
Translating the word problem into an algebraic equation, we have;
A + C = 738 .......equation 1
1.5C + 2C = 1306 .......equation 2
A = 738 - C .......equation 3
Substituting eqn 3 into eqn 2, we have;
1.5(738 - C) + 2C = 1306
1107 - 1.5C + 2C = 1306
1306 - 1107 = 2C - 1.5C
199 = 0.5C
C = 199/0.5
C = 398 children.
Now, to find the value of A.
From equation 3;
A = 738 - C
A = 738 - 398
A = 340 adult.
The legs of a right triangle measure 5 inches and 9 inches.
What is the measure of the smallest angle of the triangle?
Enter your answer, rounded to the nearest tenth of a degree, in the box.
Answer:
29.1
Step-by-step explanation:
Use logic.
Jk. Tan(x) = 5/9 so x = tan^-1(5/9)
Use a graphing calculator in degrees mode.
The measure of the smallest angle of the triangle would be equal to 29.1
What are trigonometric identities?Trigonometric identities are the functions that include trigonometric functions such as sine, cosine, tangents, secant, and, cot.
A right-angle triangle is a triangle that has a side opposite to the right angle the largest side and is referred to as the hypotenuse. The angle of a right angle is always 90 degrees.
We are given that the legs of a right triangle measure 5 inches and 9 inches.
We need to find the measure of the smallest angle of the triangle
Tan(x) = 5/9
Therefore, we have;
x = tan^-1(5/9)
x = 29.1

whats warmer -3 or -4 degree celcius
Help pleaseee I need some assistance right now
Answer:
69°
Step-by-step explanation:
if CA and AT are congruentsides, this means that the angle of C and T must also be the same.
In order for a triangle to be a triangle, they must meet the angle of 180 degrees.
We know CAT is = to 42
So we subtract 42 from 180 = 138 degrees
we then divide 138 by 2 and we get 69
angles c + t are both 69 degrees
Answer:
69°
Step-by-step explanation:
The measure of angle A is given as 42 and the sum of interior angles in a triangle is equal to 180° we subtract 42 from 180 and divide the result with 2 because this is an Isosceles triangle since |AC| = |AT| m<C = m<T
(180 - 42) ÷ 2 = 69°
Moshde runs a hairstyling business from her house. She charges $45 for a haircut and style. Her monthly expenses are $960. She wants to be able to put at least $1,200 per month into her savings account order to open her own salon. How many “cut & styles” must she do to save at least $1,200 per month?
Answer:
48 cuts and styles
Step-by-step explanation:
Moshde needs to make 48 haircuts and style per month to save $1,200.
Moshde makes $45 per haircut and yet incurs $960 in expenses every month.
She needs to cut enough hair that she makes the $960 in expenses and then a further $1,200 that she can put in savings.
The formula to find out the number of cuts she needs to make is:
= (Monthly expenses + Desired profit) / Profit per cut
= (960 + 1,200) / 45
= 2,160 / 45
= 48 hair cuts and style
In conclusion, Moshde needs to make 48 haircuts per month.

Alejandro was curious if sample median was an unbiased estimator of population median. He placed ping pong balls numbered from 000 to 323232 in a drum and mixed them well. Note that the median of the population is 161616. He then took a random sample of 555 balls and calculated the median of the sample. He replaced the balls and repeated this process for a total of 505050 trials. His results are summarized in the dotplot below, where each dot represents the sample median from a sample of 555 balls. A dot plot for a sample median has a scale from 0 to 30. The number of dots for each is as follows. 0, 0. 1, 0. 2, 0. 3, 0. 4, 1. 5, 1. 6, 2. 7, 1. 8, 0. 9, 1. 10, 5. 11, 3. 12, 2. 13, 4. 14, 1. 15, 3. 16, 4. 17, 4. 18, 1. 19, 2. 20, 4. 21, 2. 22, 0. 23, 1. 24, 2. 25, 1. 26, 1. 27, 0. 28, 2. 29, 2. 30, 0. Based on these results, does sample median appear to be a biased or unbiased estimator of population median
Answer:
Sample median appears to be an unbiased estimator of the population median
Step-by-step explanation:
The sample median appears to be centered near 16
The required sample median appears to be an unbiased estimator of the population median
