Rachel ate 3/8 of the pizza in total from pepperoni pizza and cheese pizza.
What is an expression?The mathematical expression combines numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.
Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also denote the logical syntax's operation order and other properties.
Given that Rachel ate 1/8 of the pepperoni pizza and 1/4 of the cheese pizza.
The total pizza eaten will be calculated as,
1/4 = 2/8
1/8 + 2/8 = 3/8
Hence, Rachel ate 3/8 of the pizza in total from pepperoni pizza and cheese pizza.

Find a 95% confidence interval for the true population proportion.
In a survey of 765 employees of a large company, 30% said that they had high job satisfaction.
Answer:
The 95% confidence interval for the true population proportion is (0.27, 0.33).
Step-by-step explanation:
The (1 - α)% confidence interval for population proportion of is:
[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
The information given is:
[tex]\hat p=0.30\\n=765\\\text{Confidence level}=95\%[/tex]
The critical value of z for 95% confidence level is, 1.96.
Compute the 95% confidence interval for the true population proportion as follows:
[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
[tex]=0.30\pm 1.96\times\sqrt{\frac{0.30(1-0.30)}{765}}\\\\=0.30\pm 0.0325\\\\=(0.2675, 0.3325)\\\\\approx (0.27, 0.33)[/tex]
Thus, the 95% confidence interval for the true population proportion is (0.27, 0.33).

Step-by-step explanation:
1) x+y=37
x-y=13 or x=13+y
Put x=13+y into equation 1:
13+y+y=37
y+y=24
y=12
x=25
Order of operation with Integers
Answer:
8
Step-by-step explanation:
we have to follow PEDMAS.
what we have to do in each operation:
Parenthesis ~ 100 + 8 to the second power
Exponents ~ 10 to the 2nd power, 8 to the 2nd power, 2 to the 3rd power
Multiplication ~ none
Division ~ 10 to the 2nd power - (100 + 8 to the second power) divided by 2 to the 3rd power
Addition ~ 100 + 8 to the 2nd power
Subtraction ~ 10 to the 2nd power - (100+8 to the second power)
doing the work:
we start with P: but in what we have to do in the Parenthesis, there is an exponent and addition. we do the exponent first. 8 to the second power is 64. now we can add. 100 + 64 = 164.
E: we did the 2nd exponent, but we need the other 2 for later. 10 to the 2nd power is 100, and 2 to the 3rd power is 8.
we can skip M because there isn't any multiplication to do.
D: we have to do 10 to the 2nd power - (100 + 8 to the second power) first. 100-164= 64. now we can devide. 64 devided by 8 = 8
A: we already did the addition in the parenthesis part.
S: we already did the addition in the parenthesis part.

UT is the midsection of triangle QRP. If UT= x+9 and QP=4x-27, what is the length of QP?
Answer:
Step-by-step explanation:
4x - 27 = 2(x + 9)
2x = 27 + 18
x = 45 ÷ 2 = 22.5
QP = 4(22.5) - 27 = 63 units

1. m ≥ -28/5
2. m ≤ -28/5
3. m ≥ -18/5
4. m ≤ -18/5
Answer:
Number 1
Step-by-step explanation:
-5(m + 1) ≤ 23
Distribute
-5m - 5 ≤ 23
-5m ≤ 23 + 5
-5m ≤ 28
-m ≤ 28/5
Since we divide by a negative the ≤ flips to ≥
m ≥ -28/5

Solve the proportion 20/3=?/6
Answer:
40
Step-by-step explanation:
3x2=6 so 20x2=40. It is a 6.66:1 ratio.
The value of the unknown number in the equation 20/3 = ?/6 is 40.
What is the value of the missing number?Given the equation in the question:
20/3 = ?/6
To solve the equation 20/3 = ?/6, first represent the missing number with x:
20/3 = x/6
Cross-multiply and solve for the unknown value.
x × 3 = 20 × 6
Multiply 3 and x:
3x = 20 × 6
Multiply 20 and 6:
3x = 120
Next, divide both sides by 3:
3x/3 = 120/3
x = 120/3
x = 40
Therefore, the value of x is 40.

Applying the exterior angle of a triangle theorem, m<WUV = 36°
What is the Exterior Angle of a Triangle Theorem?The exterior angle of a triangle theorem states that the measure of the angle formed, when one side of a triangle is extended, is equal to the sum of the opposite interior angles of that triangle.
Applying the exterior angle of a triangle theorem:
m<WUV + m<UVW = m<VWX
Substitute
2x + 8 + 3x + 16 = 8x - 18
Add like terms
5x + 24 = 8x - 18
5x - 8x = -24 - 18
-3x = -42
-3x/-3 = -42/-3
x = 14
m<WUV = 2x + 8
Plug in the value of x
m<WUV = 2(14) + 8
m<WUV = 28 + 8
m<WUV = 36°
Therefore, applying the exterior angle of a triangle theorem, m<WUV = 36°
