Answer:
sin 60 =√3/2 = 0.8660
Step-by-step explanation:
sin 60 = opposite/hypotenuse
sin 60 = x√3/2x
sin 60 = √3/2 since x cut x
sin 60 = 0.8660 or √3/2
What is the value of x? Please help
Answer: x = 21
Step-by-step explanation:
5x + (3x + 12) = 180
8x + 12 = 180
8x = 168
168/8 = 21
Suppose you were to draw all possible samples of size 36 from a large population with a mean of 650 and a standard deviation of 24. You then compute the sample mean x-bar for each sample. From the long list of sample means, you create the sampling distribution of the sample mean, assigning probabilities to all possible values of x-bar.
Required:
What is the shape of the sampling distribution you would expect to produce?
Answer:
By the Central Limit Theorem, it is approximately normal with mean 650 and standard deviation 4.
Step-by-step explanation:
Central Limit Theorem
The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].
For a skewed variable, the Central Limit Theorem can also be applied, as long as n is at least 30.
Mean of 650 and a standard deviation of 24.
This means that [tex]\mu = 650, \sigma = 24[/tex].
Sample of 36:
This means that [tex]n = 36, s = \frac{24}{\sqrt{36}} = 4[/tex]
What is the shape of the sampling distribution you would expect to produce?
By the Central Limit Theorem, it is approximately normal with mean 650 and standard deviation 4.
All employees in Department A attend the sales training programme. Some employees in Department A attend the technical training programme. Some employees who attend both training programmes are in Department B. Conclusion: All employees who attend the sales training programme and who attend the technical training programme are in Department A. If the assumptions are true, is the conclusion:
a. Correct
b. Cannot be determined based on the information available
c. Incorrect
Answer:
c. Incorrect
Step-by-step explanation:
According to the third sentence in assumption "Some employees who attend both training programmes are in Department B.", it is clear that there are certain employees in department B, who are attending both the training. Hence, all the employees who attend the sales training programme and who attend the technical training programme are not in Department A. Some of them are in department B as well.
Therefore, the conclusion is not correct and the final answer is:
c. Incorrect

The admission fee at an amusement park is $3.50 for children and 13.00 for adults. On a certain day, 288 people entered the park, and the admission fees collected totaled $2,338.00. How many children and how many adults were admitted?
There were ___ children and ____ adults admitted into the park
Answer:
148 children and 140 adults were admitted.
Step-by-step explanation:
Given that the admission fee at an amusement park is $ 3.50 for children and $ 13.00 for adults and on a certain day, 288 people entered the park, and the admission fees collected totaled $ 2,338.00, to determine how many children and how many adults were admitted you must be perform the following calculation:
13 - 3.5 = 9.50
288 x 3.50 = X
1.008 = X
2338 - 1008 = 1330
1330 / 9.5 = 140
288 - 140 = 148
148 x 3.5 + 140 x 13 = X
2338 = X
Therefore, 148 children and 140 adults were admitted.
Which of the following is always one of the data values in a data set?
Answer:
mean
Step-by-step explanation:
1. The mean is always one of the data values. 3. The mode is always one of the data values.
Answer: The mode.
Step-by-step explanation: The answer to this question is the mode, the answer is mode because there might be some numbers that show up the same amount of times like a different number. So there might be TWO modes :’).
Here are the definitions for mean, median, mode, and range:
Mean (the “average”) —> the sum of the numbers in the data set divided by the amount of numbers in the data set.
Median (the “middle”) —> the number in the middle of the data set, when the numbers are placed in numerical order.
Mode (the “most”) —> the number in the data set that shows up the most often.
Range —> the difference between the data set’s largest number and the data set’s smallest number.

Determine if lines AB and CD are parallel, perpendicular, or neither. A(5,-8), B(-2,-10), C(-6,-13), D(-2,1)
Answer: The answer is neither because the slopes are 2/7 and 7/2.
Step-by-step explanation:
While these answers look like they are perpendicular, they are not since the signs are the same. If they were perpendicular the signs would be different. Ex: 2/7 and -7/2. These points are perpendicular since their signs changes as well as being "flipped".

One electrician charges a flat fee of $55 to come to the house, $20 per
hour, and the cost of all materials. If h represents the number of hours that
the electrician spent fixing the problem, C represents the total charge, and m
represents the cost of materials, which of the following equations shows how
to determine the total fee charged?
C=20+55h+m
C=mh+55 +20
C=(55+20)h+m
C=55+20h+m
Answer:
C=55+20h+m
Step-by-step explanation:
C = flat fee + dollars/hour + material expense
C = 55 + 20h + m

how is y=2x^2-8x+9 rewritten in vertex form.
9514 1404 393
Answer:
y = 2(x -2)^2 +1
Step-by-step explanation:
Start by factoring the leading coefficient from the x-terms.
y = 2(x^2 -4x) +9
Now identify the coefficient of x, -4, and figure half of that: -2. Square this number and add it inside the parentheses. At the same time, subtract the equivalent value outside parentheses. (The leading coefficient must be taken into account.)
y = 2(x^2 -4x +4) +9 -2(4)
Put in the desired form.
y = 2(x -2)^2 +1
This matches vertex form ...
y = a(x -h)^2 +k . . . . . . . . . vertical scale factor 'a'; vertex (h, k)

A father has four sons, with heights of 68, 71, 72, and 75 inches. Determine the sampling distribution of
the sample mean height and the sampling distribution of the sample range of height for samples of
size n= 2.
The sampling distribution of the sample mean height and the sampling distribution of the sample range of height are 71.5 inches and 7 inches.
What is a mean?It is the average value of the set given.
It is calculated as:
Mean = Sum of all the values of the set given / Number of values in the set
We have,
Heights: 68, 71, 72, and 75 inches
Now,
Mean height.
= (68 + 71 + 72 + 75) / 4
= 286/4
= 71.5 inches
Sample range.
= Highest height - Lowest height
= 75 - 68
= 7 inches
Thus,
The mean height is 71.5 inches.
The sample range of height is 7 inches.

1) 14 units2 2) 16 units2 3) 17 units2 4) 19 units2
Answer:
4th option: 19 units2Step-by-step explanation:
The given figure can be divided as (i) upper rectangle, (ii) lower rectangleThen,
(i) Breadth of upper rectangle = 2 units
Length of upper rectangle = 8 - 1 = 7 units
Therefore,
Area of the upper rectangle = 7 × 2 = 14 units2
(ii) Breadth of lower rectangle = 1 unit
Length of lower rectangle = 5 units
Therefore,
Area of the lower rectangle = 5 × 1 = 5 units2
Since,
Area of the figure is = Area of upper rectangle + Area of lower rectangle
= 14 units2 + 5 units2
= 19 units2 (Ans) (4th option)
