Find the mean of the following set of numbers. 4,10,12,8,6
Answer:
Mean = 8
Step-by-step explanation:
The mean is another way of describing the average. To find the mean, you need to (1) add all of the numbers together and (2) divide by the amount of numbers added.
(Step 1)
4 + 10 + 12 + 8 + 6
= 40
(Step 2)
4, 10, 12, 8, 6 -----> There are 5 numbers
40 / 5

A computer randomly picks a number from the group 20, 21, 22, 23, 24, 25, 26, 27. What is the probability the number is greater than 24 or less than 21?
Answer:
The answer you're looking for is .5
Step-by-step explanation:
Cause 20 is less than 21, and 25, 26, and 27 is larger than 24, and that's 4 numbers. There's 8 numbers in total, so your answer is 4/8. Divide that by 4, and you get 1/2. That's 50%, if you're thinking out of "1" then it would be ".5"
Answer: 0.5 or 50%
Numbers-Set {20, 21, 22, 23, 24, 25, 26, 27}
Total outcomes: 8
numbers greater than 24 are 25, 26, 27 - 3 numbers
number less than 21 is 20 - 1 number
Total favorable outcomes: 3 + 1 = 4
Probability = favorable outcomes/total outcomes = 4/8 = 0.5

Answer:
108 cm²
Step-by-step explanation:
The composite shape can be divided as shown into a trapezoid and a triangle. The area of the shape is the sum of the areas of those parts.
__
trapezoidThe top portion of the shape is marked as a trapezoid with bases 12 cm and 6 cm, and height 6 cm. Its area is given by ...
A = 1/2(b1 +b2)h
A = 1/2(12 cm +6 cm)(6 cm) = 1/2(18 cm)(6 cm) = 54 cm²
__
triangleThe bottom portion of the shape is marked as a triangle. The triangle has a base of 12 cm and a height of (15 cm -6 cm) = 9 cm. Its area is ...
A = 1/2bh
A = 1/2(12 cm)(9 cm) = 54 cm²
__
total areaThe area of the composite figure is the sum of the areas of its parts:
total area = trapezoid area + triangle area
total area = 54 cm² +54 cm² = 108 cm²
The area of the logo is 108 cm².

Calculating the measured of anglesFrom the question, we are to determine the measures of the angles
i) acute ∠AOB
From the given diagram,
∠AOB = 10°
ii) acute ∠COD
From the given diagram,
∠COD= 25°

Calculate the perimeter of the triangle for problems
B. Calculate the area of the triangle for problems
Answer:
To calculate the perimeter of a triangle, add the length of its sides. For example, if a triangle has sides a, b, and c, then the perimeter of that triangle will be P = a + b + c.
Answer:
1) 21.24cm
2)19.8ft
3)22.84mm [2.284cm]
Step-by-step explanation:
To calculate the perimeter of a triangle, add the length of its sides.
1) perimeter = 5.4+8.84+7
=> 5.4+8.84+7 = 21.24,
21.24cm
2) perimeter = 6.6 + 6.6 + 6.6 i.e 6.6* 3
=> 6.6 x 3 = 19.8
19.8ft
3) perimeter = 8.3 + 4.9 + 9.64
=> 8.3 + 4.9 + 9.64 = 22.84
22.84mm or 2.284cm
AREA
1) it's a right triangle,
=> Area of a right triangle = 1/2 × base × height.
=> here, base is a and height is b
=> a = 7, b = 5.4
=> now we multiply it,
=> 7*5.4 = 37.8
=> now multiply it with 1/2,
=> 1/2 x 37.8 = 37.8/2
=> 37.8/2 = 18.9
2) it's an equilateral triangle,
18.8620
the formula is √3 a^2/ 4
=> √3* 6.6^2/ 4
=> 75.4481/4 = 18.8620
3) 20.335
base = a = 8.3
height = b = 4.9
=> 8.3 * 4.9 = 40.68
=> 40.68/2 = 20.335

Write an equation for the line that is parallel to the given line that passes through the given point.
y = -6x + 2; (-1,2)
Answer:
The correct answer is y = -6x - 4
Step-by-step explanation:
The given equation of the line : y = -6x + 2
Now, the general equation of the line in the slope-intercept form is given by : y = mx + c
Now, comparing the given equation with the general form, We get slope, m = -6
We need to find the equation of the line which is parallel to the given line and since the slope of two parallel lines are equal so the slope of the required line will also be -6
And it passes through the point (-1, 2)
The required equation will be :
⇒ y - 2 = -6 × (x + 1)
⇒ y - 2 = -6x - 6
⇒ y = -6x - 4
Therefore, The required equation is y = -6x -4
Hence, The correct answer is. y = -6x - 4

Answer:
342
Step-by-step explanation:
First, there are 9 one-digit numbers, so 9x1=9. Next, there are 90 two-digit numbers, so 90x2=180. There are 51 numbers between 100-150, so 51x3=153. Now, we do 9+180+153=342 digits.

Break the numbers down by the number of digits in that sequence.
Number of digits 1 to 9 = 9
Number of digits from 10 to 99
There are 90 numbers between 10 and 99
Each has 2 digits
The total number of digits is 180
Number of digits from 100 to 150
There are 51 numbers between 100 and 150
Each has 3 digits
The total number of digits = 3*51 153 Add

If a company reports operating profit of $70 million, earns net income of $50 million in year 8, has 20 million shares of common stock outstanding, pays a dividend of $1. 50 per share, and has annual interest costs of $15 million--all in year 8, then
The company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million
How do we calculate EPS and retained earnings?Note: The options for the questions are as follows:
A. the company's total earnings for Year 8 would be $10 million (net income of $50 million less interest costs of $10 million less dividend payments of $30 million = $10 million).
B. the company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million (net income of $50 million less dividend payments of $30 million).
C. the company's credit rating would be no less than an A because operating profit is seven times higher than annual interest costs.
D. the company's EPS for Year 8 would be $5.50 and its retained earnings for Year 8 would be $10million (net income of $50 million less interest costs of $10 million less dividend payments of $30million).
E. the company's EPS for Year 8 would be $1.50 (operating profit of $70 million less interest costs of$10 million, less dividend payments of $30 million= $30 million divided by 20 million shares).
The question can now be answered as follows:
From the question, we can calculate the following:
EPS = Net income / Number of shares of common stock outstanding = $50 million / 20 million = $2.50
Dividend payments = Number of shares of common stock outstanding * Dividend per share = 20 million * $1. 50 = $30 million
Retained earnings = Net income - Dividend payments = $50 million - $30 million = $20million
Therefore, the correct option is B. the company's EPS for Year 8 would be $2.50 and its retained earnings for Year 8 would be $20 million (net income of $50 million less dividend payments of $30 million).

A jeweler wants to combine a 60% gold alloy with a 20% gold alloy to make 1000 grams of 50% gold alloy. How many grams of 60% alloy should be used?
Answer:
750 grams of 60% alloy
Step-by-step explanation:
Define x = amount of 60% alloy and y = amount of 20% alloy
Equating the amounts of gold:
0.6x+0.2y = 1000(0.5)
Since there must be 1000 grams total:
x+y = 1000
Writing the 2 resulting equations together:
0.6x + 0.2y = 500
x + y = 1000
Multiply the first equation by 5:
3x + y = 2500
x + y = 1000
Subtracting the 2nd equation from the 1st:
2x = 1500
x = 750
Answer: 750 grams of 60% alloy

Step-by-step explanation:
I don't know what Alls are, but if Carlos insists, we can calculate how much he can spend on Alls with the expression:
($31.50) + r [tex]\leq[/tex] $40
This says the sum of what Carlos has already spent (hot dogs and hamburgers) plus the amount he spends on Alls (rolls?), r, must be equal to or less than the $40 he has allowed himself to spend.

The graph of a linear function f passes through
the point (1,4) and has a slope of -2.
What is the zero of f?
Answer:
x = -1
Step-by-step explanation:
(x1,y1) = (1,4) and m = 2
(y-y1)/(x-x1) = m
derive the linear function first before finding the zero.
(y-4)/(x-1) = 2
cross multiply
y-4 = 2(x-1)
y-4= 2x - 2
y = 2x - 2+4
y. = 2x + 2 is the linear equation
at y = 0 gives the zero
2x + 2 = 0
2x = -2
x = -2/2
x = -1 is the zero
