Answer:
A, C, T
Step-by-step explanation:
A subset simply means a set of which all of its elements are contained in a larger set :
To obtain the subsets of B={1,2,3,4,5,6,7,8,9,10}.
We observe the smaller sets whose entire elements can be found in B
D={0,2,4,6,8,10,12} = not a subset of B ; B does not contain 0
A={5,6,7} = subset of B, all elements Cann be found in B
C={2} = subsets of B, 2 can be found in B
T={1,2,3,4,5,...,8} = subset of B; all elements can be found in B

find the value of using property of 3295×999+3295 Solution
Answer:
3295000
Step-by-step explanation:
3295×999+3295
3295 * 999 = 3291705
3295×999+3295
3295 * 999 + 3295
3291705 + 3295 = 3295000
Suppose you are interested in investigating the wage gender gap using data on earnings of men and women. Which of the following models best serves this purpose?
A. Wage=βo +β1, Female + u, where Female (=1 if female) is an indicator variable and u the omor term.
B. Wage =βo + u where u is the error term.
C. Female= βo+ β1 Wage + u where Female (=1 if female) is an indicator variable and u the error term.
D. Male =βo+β1 Female+ u where Male (=1 if male) is an indicator variable and u the error term
Consider the regression model
Wage=βo + β1Female + u
Where Fomale (=1 if female) is an indicator variable and u the error term.
Identify the dependent and independent variables in the regression model above.
Wage is the__________ variable, while FP the ________ varlabie.
Answer:
A. Wage=βo +β1, Female + u, where Female (=1 if female) is an indicator variable and u the error term.
Wage = dependent variable
FP = Independent variable.
Step-by-step explanation:
The model selected model shows the relationship between the wages earned by male and female gender based on earnings of the two gender groups.
Wage is the dependent variable while factors upong which their wage depends on will be adopted as the independent variable. Since gender is categorical and cannot be used in that form during regression analysis. The it can be converted into a dummy or encoded variable. Such as treating female as = 1.
24-67-88+77-77+78-55+888
Answer:
780
Step-by-step explanation:
24 - 67 = - 43
- 43 - 88 = - 131
- 131 + 77 - 77 = - 131
- 131 + 78 = - 53
- 53 - 55 = - 108
- 108 + 888 = 780

Answer:
10m = height
Step-by-step explanation:
Volume of a Cylinder = πr²(h), where r is the radius and h is the heigh of the circle, therefore;
=> 1000π = π(10)²(h)
=> 1000π = 100π(h)
=> 1000π/100π = h
=> 10 = h
Hope this helps!

A = 28.26 sq yds
Step-by-step explanation:
diameter (D) = 6 yds
radius (r) = D/2 = 3 yds
A = πr^2
= (3.14)(3 yds)^2
= 28.26 sq. yds
The function g(x) =x^2 is transformed to obtain function h:
h(x) = g(x) + 1.
Which statement describes how the graph of h is different from the graph of g?
OA.

The sum of two numbers is 32. One number is 10 more than the other. Find the numbers
Answer:
12 and 10
Step-by-step explanation:
Answer:
11 and 21
Step-by-step explanation:
Let the first number equal x. If the first number, the second number is ten more, and can represented as x + 10. Now, the sum is 32, so we can add the two numbers to get 32:
x + x + 10 = 32
2x + 10 = 32
2x = 22
x = 11
If the first number 11, the second number is 10 more, and therefore is 21.

Answer:
b) 7x² - 12x√14 + 72
Step-by-step explanation:
Let's solve the problem,
→ (x√7 - 3√8)(x√7 - 3√8)
→ (x√7 - 3√8)²
→ 7x² - 12x√14 + 72
Hence, option (b) is correct.
solve for x.
there’s a 76 and x.
Answer:
104
Step-by-step explanation:
The angle is supplementary, so the total angle measure (of 79 and x) is 180. Just subtract the value we have (76) from the total value (180), and you get x.
A window in the shape of a rectangle as shown below has a width of 2X +1 and the length of X squared minus 5X -7
Answer;
14x-12
Explanation:
Since we are not asked what to fine, we can find the perimeter of the rectangle
Perimeter = 2(L+W)
Perimeter = 2(2x+1+5x-7)
Perimeter = 2(7x - 6)
Perimeter = 14x - 12
Hence the perimeter of the rectangle is 14x-12
Find the median of the data in the dot plot below.
Answer:
The median is 6.
Step-by-step explanation:
To find the median, put the numbers in order then find the middle number. In this data set, there are 2 numbers, so you add those 2 and divide by 2.
5+7 equals 12. 12 divided by 2 is 6.
Find the area and perimeter of the figure below
Answer:
p ≈ 97 cm

Step-by-step explanation:
First figure out the missing lengths
The triangle on the right is a standard 9 - 12 - 15 right triangle
The triangle in the left is a right isosceles triangle so the sides are both the same 12cm. The hypotenuse is found using c² = a² + b² and is approx 17 cm
--------------------------
perimeter
p ≈ 12 + 22 + 9 + 15 + 22 + 17
p ≈ 97 cm
Area
a = left triangle + rectangle + right triangle
a = (1/2)(12*12) + (12*22) + (1/2)(9*12)
a = 390 cm²

Find The length of one leg of a right triangle if the length of the hypotenuse is 18 feet and the length of the other leg is 14 feet. Leave your answer as a simplified radical.
Answer:
a = 8√2
Step-by-step explanation:
a² + b² = c²
a² +14² = 18²
a² + 196 = 324
Subtract 196 from both side
a² = 128
Take the square root of both sides
a = √128
a = √(64 * 2)
a = 8√2

Nicholas performs an experiment in which he pulls a marble from a bag. In his experiment, he finds that he is twice as likely to pull a red marble as a blue marble. If Nicholas pulls 10 red marbles, how many blue marbles does he pull?
Answer:
Nicholas pulls 5 blue marbles from the bag.
Step-by-step explanation:
Since Nicholas performs an experiment in which he pulls a marble from a bag, and in his experiment, he finds that he is twice as likely to pull a red marble as a blue marble, to determine, if Nicholas pulls 10 red marbles, how many blue marbles does he pull, the following calculation must be performed:
10/2 = X
5 = X
Therefore, Nicholas pulls 5 blue marbles from the bag.
Two lines and a ray intersect to form five angles. The angles are numbered in the diagram 1 through 5.
If the measure of ∠4 is 55°, what is the measure of ∠2?
Answer:
[tex]\angle 2 =145^\circ[/tex]
Step-by-step explanation:
Given
[tex]\angle 4 = 55^\circ[/tex]
Required
Find [tex]\angle 2[/tex]
From the attached image, we have:
[tex]\angle 5 = 90[/tex] --- right angle
So, we have:
[tex]\angle 5 +\angle 4 = 90 + \angle 4[/tex]
Substitute: [tex]\angle 4 = 55^\circ[/tex]
[tex]\angle 5 +\angle 4 = 90 + 55[/tex]
[tex]\angle 5 +\angle 4 = 145[/tex]
To solve for [tex]\angle 2[/tex], we have:
[tex]\angle 2 =\angle 5 +\angle 4[/tex] --- Vertically opposite angles
So:
[tex]\angle 2 =145^\circ[/tex]
