What is the solution set of \ x|x<-3\ cap\ x|x>5\ ?
Answer:
Let set A = {x|x<-3}
Let set B = {x|x>5}
The solution for set A could be graphically represented with a number line that contained an unshaded circle surrounding the integer -3 and all values to the left or less than -3 would be shaded.
The solution for set B could be graphically represented with a number line that contained an unshaded circle surrounding the integer 5 and all values to the right of 5 or greater than 5 would be shaded.
If you placed the two number lines close to each other, you would see that they do not intersect.
Thus there is no solution for the intersection of set A and set B as defined in the given problem.

Convert 1AA from hexadecimal to decimal.
1AA = 426
What an odd class...
Answer:
426 in decimal.
Step-by-step explanation:
Step 1) Count the digits in 1AA, which in this case is 3 digits, and convert each digit to Hex.
Step 2) Starting from the last number in Step 1, multiply the first number with 1, the second number with 16, and the third number with 256.
Step 3) Add up all the numbers you got in Step 2 to get the answer.
Following the instructions above, your math should look like this:
10 x 1 = 10
10 x 16 = 160
1 x 256 = 256
10 + 160 + 256 = 426
Thus, we got the following answer:
1AA = 426
If a function is defined by the formula y=1/2x + 3 and its domain is given by the set {-4,0,8}, then which of the following sets gives the function's range?
Answer:
y = {1, 3, 7}
Step-by-step explanation:
Given
y = ½x + 3
Domain: {-4, 0, 8}
Required
Determine the range of the function
To do this, we simply substitute each value of the domain in the given expression
We start with the first
Substitute -4 for x in y = ½x + 3
y = ½ * -4 + 3
y = -2 + 3
y = 1
Then 0
Substitute 0 for x in y = ½x + 3
y = ½ * 0 + 3
y = 0 + 3
y = 3
Lastly, 8
Substitute 8 for x in y = ½x + 3
y = ½ * 8 + 3
y = 4 + 3
y = 7
Hence, the range of the function is:
y = {1, 3, 7}
Answer:1,3,7
Step-by-step explanation:
Simplify the expression:
8(x - 5) + 7(3x + 4)
Answer:
29x-12
Step-by-step explanation:
29x-12
Step-by-step explanation:
8•x=8×
8•-5=-40
7•3x=21x
7•4=28
-40+28=-12
21x+8x=29x
The area of a rectangular painting is 8613 cm?.
If the length of the painting is 99 cm, what is its width?
Answer:
The width is 87 cm
Step-by-step explanation:
The area of a rectangle is given by
A = l*w
8613 = 99 * w
Divide each side by 99
8613 / 99 = 99 w /99
87 = w
The width is 87 cm
Answer:
Step-by-step explanation:
Given
The area of a rectangular painting=8613 cm^2
Length of painting=99cm
Solution
Area of the rectangular painting=8613
Length×width=8613
99×width=8613
Width=8613/99
Width =87cm

A tile factory earns money by charging a flat fee for delivery and a sales price of $0.25 per tile. One customer paid a total of $3,000 for 10,000 tiles. The equation y – 3,000 = 0.25(x – 10,000) models the revenue of the tile factory, where x is the number of tiles and y is the total cost to the customer.
Which function describes the revenue of the tile factory in terms of tiles sold?
The answer is 1.C 2.$500

Suppose that the amount of snowfall per storm in Lincoln is normally distributed with µ = 4.2 inches and standard deviation µ = 2.3 inches (totally made up data). If the mayor decides that only the top 5% of storms should have school cancelled, what is the cutoff snowfall for school to be cancelled?
Answer:
7.9835
Step-by-step explanation:
Given that :
Mean snowfall per storm (µ) = 4.2 inches standard deviation (s) = 2.3 inches
Only the top 5% of storm should result in school being canceled :
Cut off snowfall for school to be canceled '
P(Z ≥ 5%) ; p(Z ≥ 0.05) = 1.645
Using the z relation :
Z = (x - m) / s
1.645 = (x - 4.2) /2.3
x - 4.2 = 2.3 * 1.645
x - 4.2 = 3.7835
x = 3.7835 + 4.2
x = 7.9835
Cut off snowfall for school to be canceled 7.9835

I need help with this.
Answer:
C
Step-by-step explanation:
(-2,4) means that it excludes the numbers -2 and 4 from the set, but includes all the numbers in between -2 and 4!
A. this equals 4, so that's eliminated.
B. this equals -2, eliminated as well.
C. this equals 0.01! Which is in the set!
D. this equals 9.8696, WAY over 4!
The answer is C!
(side note, (-2,4) excludes -2 and 4, while [-2,4] includes -2 and 4. You can mix and match also! (-2,4] would exclude -2 but include 4, for example)

Find endpoints on a standard normal distribution with the given property. The area between is about 0.88 . Round your answers to three decimal places and place the endpoints in increasing order.
Answer:
-1.555 and 1.555
Step-by-step explanation:
For a standard normal distribution:
P(- Ƶ ≤ Z ≤ Ƶ) = 0.88
The normal distribution on the curve is symmetrical about Z = 0
Thus
P( -Ƶ ≤ Z ≤ 0) = P( 0 ≤ Z ≤ Ƶ)
However;
This implies that:
P( -Ƶ ≤ Z ≤ 0) + P( 0 ≤ Z ≤ Ƶ) = 0.88
2P ( 0 ≤ Z ≤ Ƶ) = 0.88
P( 0 ≤ Z ≤ Ƶ) = 0.44
P(Z ≤ Ƶ) - P( Z ≤ 0) = 0.44
Since P(Z ≤ 0) = 0.50
P(Z ≤ Ƶ) = 0.44 + 0.50
P(Z ≤ Ƶ) = 0.94
From the probability value table
z = 1.555
Thus the endpoints are:
-1.555 and 1.555
Alexander spent a total of 12.5 hours on a science project for the Science Fair. His sister, Laura, spent 16.6 hours on a science project. How many more hours did Laura spend on her project than Alexander spent on his?
Answer:
4.1 I think
Step-by-step explanation:
I just subtracted in my head
Answer:
4.1 hours
Step-by-step explanation:
Laura spent 4.1 more hours on her project than Alexander spent on his. If we split each number into 2 parts (like this: 12.5 -> 12 and .5; 16.6 -> 16 and .6) then we can subtract 12 from 16 and .5 from .6 to get 4 and .1. we add those together to get 4.1
tell whether the transformation appears to be a rigid motion. explain
Answer:
If you turn it or flip it over or move it it is essentially the same shape. If you try to stretch the paper or fold it you change what the shape is so it is not a rigid motion. Since the two circles are not the same size then it is not a rigid motion
Find the slope between the points. �. (5, −3) (7, 4)
Answer: slope is [tex]\frac{7}{2}[/tex] or 3.5
Step-by-step explanation:
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] = [tex]\frac{4-(-3)}{7-5}[/tex] = [tex]\frac{7}{2}[/tex]
Answer:
[tex]\boxed {\boxed {\sf m= \frac{7}{2} \ or \ 3.5 }}[/tex]
Step-by-step explanation:
The slope formula is the change in y over the change in x.
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
In this formula, (x₁, y₁) and (x₂, y₂) are the points given. We are given the points (5, -3) and (7,4). Therefore,
[tex]x_1=5 \\y_1= -3\\x_2=7 \\y_2=4[/tex]
Substitute the values into the formula.
[tex]m=\frac{4--3}{7-5}[/tex]
Solve the numerator.
4 - -3 = 4+3 = 7[tex]m=\frac{7}{7-5}[/tex]
Solve the denominator
7-5=2[tex]m=\frac{7}{2}[/tex]
[tex]m=3.5[/tex]
The slope between the points is 7/2 or 3.5
