Please help me, there is a screenshot of the question below
Answer:
3?
Step-by-step explanation:
Solve y=f(x) for x. Then find the input when the output is – 3.
f(x) = 1/2x-3
x=
The input is
when the output is -3.
Given:
[tex]y=f(x)[/tex]
[tex]f(x)=\dfrac{1}{2}x-3[/tex]
To find:
The input when the output is – 3.
Solution:
We have,
[tex]f(x)=\dfrac{1}{2}x-3[/tex]
Substituting [tex]f(x)=y[/tex], we get
[tex]y=\dfrac{1}{2}x-3[/tex] ...(i)
We need to find the input when the output is – 3. It means, we have to find the value of x when [tex]y=-3[/tex].
Putting [tex]y=-3[/tex] in (i), we get
[tex]-3=\dfrac{1}{2}x-3[/tex]
[tex]-3+3=\dfrac{1}{2}x[/tex]
[tex]0=\dfrac{1}{2}x[/tex]
Multiply both sides by 2.
[tex]0=x[/tex]
Therefore, the input is 0 when the output is -3.
What is the range of the data
Answer:
56
Step-by-step explanation:
The range of a box and whisker graph is the difference of the furthest point to the right and furthest point to the left. 76-20 = 56
Answer:
The range is 56.
Step-by-step explanation:
The range is the greatest value subtracted by the smallest value.
76 - 20 = 56.

The shoes you want are $95. They are on sale for 40% off . What is the sale price for the shoe ?
Answer:
57
Step-by-step explanation:
90 - 40% = 57
Answer:
The shoes would be $57
Step-by-step explanation:
To calculate percentage you use the equation:
P% x N = A
Before we use it we convert the number 40 into the tenths place of a decimal, 0.40.
Now we use it!
.40 x 95 = 38
38 would be 40%, so we remove it from the last total aka 95
95 - 38 = 57
a. Show the sampling distribution of p, the proportion of groceries thrown out by your sample respondents.b. What is the probability that your survey will provide a sample proportion within 6.03 of the population proportion
Answer:
The corresponding p - value will be is < 0.00001 which is less than 0.05
Step-by-step explanation:
Suppose p= 0.12 and n= 540 then the standard deviation can be taken out as √p(1-p)/n= √0.12(1-0.12)/540= 0.014
For the probability that the survey will provide a sample proportion within 6.03 of the population proportion
we will find the z statistic
z= p^-p/√p(1-p)/n
But √p(1-p)/n= 0.014 and p^-p= 6.03
Putting the values
z= 6.03/0.014= 430.71
The corresponding p - value will be is < 0.00001 which is less than 0.05

If A is a 2x2 matrix and B is a 2x1 matrix, what is the dimension of AB?
Answer:
2x2 matrix
Step-by-step explanation:
Given
Dimension of matrices A = 2x2 matrix
Dimension of matrices B = 2x1 matrix
The dimension of matrix AB can be gotten by cancelling the row of matrices 1 and column of matrices 2.
After cancelling both row and column, the remaining dimension will be 2x2 matrix. Hence the dimension of AB is 2x2 matrix
What is the measure of angle of 1?
Answer:
m<1 = 118
Step-by-step explanation:
The remote angles theorem states that when one extends one of the sides of a triangle, the sum of the two non-adjacent angles is equal to the measure of the angle between the extension of the side and a side of a triangle. One can apply this theorem here by stating that
(28) + (90) = m<1
Remember, a box around an angle signifies that its measure is (90) degrees.
Solve this problem by performing the operation,
118 = m<1
In most residence, the largest bedroom is considered the Masters Bedroom. Which bedroom would be considered the Masters Bedroom based on area? * bed room 2 bedroom 1
Answer:
Bedroom 2 will be considered as the Master bedroom.
Step-by-step explanation:
Area of bedroom 1 = Area of room 1 - Area of the closet 1
Area of the room 1 = Length × Width
= (2.5 + 1.4) × (4.3+0.6)
= 3.9 × 4.9
= 19.11 m²
Area of closet 1 = 1.5 × 0.6
= 0.90 m²
Area of bedroom 1 = 19.11 - 0.90
= 18.21 m²
Area of bedroom 2 = Area of room 2 - (Area of bathroom + Area of Hall)
Area of room 2 = (3 + 3.1) × (2.5 + 2.4)
= 6.1 × 4.9
= 29.89 m²
Area of bathroom = 3 × 2.5
= 7.5 m²
Area of Hall = 1.2 × 2.4
= 2.88 m²
Area of bedroom 2 = 29.89 - (7.5 + 2.88)
= 29.89 - 10.38
= 19.51 m²
Since, area of bedroom 2 is greater than bedroom 1.
Therefore, Bedroom 2 will be considered as the Master bedroom.

solution of f'(x) = 9x2+2x (-2,2)
Answer:
f(x) = 3x³ + x² + 22
Step-by-step explanation:
Given
f'(x) = 9x²+2x
To get f(x), we will be integrating the function
f(x) = 9x³/3 + 2x²/2 + C
f(x) = 3x³ + x² + C
at (-2,2)
2 = 3(-2)³ +(-2)² + C
2 = -24 + 4 + C
2 = -20 + C
C = 2+20
C = 22
Get the required function
f(x) = 3x³ + x² + C
f(x) = 3x³ + x² + 22

PEMDAS. VERY IMPORTANT. THIS ACRONYM WILL HELP YOU WHEN SOLVING MULTI-STEP PROBLEMS. IF YOU DO NOT KNOW IT, SEARCH IT UP. I'LL BE USING PART OF THIS ACRONYM TO SOLVE THIS PROBLEM.
First you solve things in paratheses:
1. (14 ÷ 2) x 5 + 6 -> (7) x 5 + 6
2. {3 x (4 + 1)} ÷ 5 -> {3 x 5} ÷ 5 -> 15 ÷ 5
Then, you multiply or divide next:
1. (7) x 5 + 6 -> 35 + 6
2. 15 ÷ 5 = 3
We already have the answer to number 2, but not number one, so we will keep going. Finally, you subtract or add:
1. 35 + 6 = 41
Now you have your answers. Hope this helps!
Mrs. Joyce calculated the class mode on her latest test. 18 students took it and the mode was 83. Three days later the four absent kids made it up and scored 77, 83, 68, and 80. What is the new mode
Answer:
83 is still the mode
Step-by-step explanation:
The maximum possible value for the new mode is 83.
What is mode?The data value that is repeated the most in the data set is called the mode of the given data set.
Given is that Mrs. Joyce calculated the class mode on her latest test. 18 students took it and the mode was 83. Three days later the four absent kids made it up and scored 77, 83, 68, and 80.
Initially, the mode of the class of 18 students is 83. This means that most of the students scored the 83 marks in the test. After four students took the test, the maximum probability that the mode will remain 83 is the highest. Also, one of the four numbers scored 83 itself.
Therefore, the maximum possible value for the new mode is 83.

What is the area of the figure?
Answer:
b. 366 square inches
Step-by-step explanation:
The area of a triangle is 1/2×Base×Height. There are 2 pairs of identical triangles so you multiply each equation by 2.
2×(1/2×10×12) = 120 in²
2×(1/2×18×12) = 216 in²
120 in² + 216 in² = 336 in²
Answer:
336 square units
Step-by-step explanation:
Generally, to find the area of the given quadrilateral (which is presumably a kite), one uses the following formula,
[tex]\frac{(base)*(hieght)}{2}[/tex]
In this picture, one can see that the diagonals (dotted lines that connect opposite corners) are given, but their measurements are split up as per the segments they are divided into. In order to find the lengths of each diagonal, add up the two parts. To find the area of the figure, substitute the results into the given formula to find the area,
[tex]12+12=24\\\\10 + 18 = 28[/tex]
Substitute,
[tex]\frac{24*28}{2}\\\\=\frac{672}{2}\\\\=336[/tex]

A summer camp has 492 campers who will be going on an outing. Estimate the number of vans needed to accommodate the entire camp if each van can comfortably
hold 12 passengers. Then calculate the actual number of vans that will be needed.
Answer: 41 vans will be needed.
Step-by-step explanation:
There are a total of 492 campers. We know that each van can hold a total of 12 passengers.
So, simply divide 492 by 12 to get the total amount of vans needed.
492/12 = 41 vans.
