Answer:
let monday be a = 800 (nearest 100)
let tuesday be b = 700 (nearest 100)
a+b = 800 + 700 = 1500
a+b = 1500

In the diagram m<8=11y+7 and m<3=y+17.What is m<2
Answer:
C. 150
Step-by-step explanation:
Given:
m<8 = 11y + 7
m<3 = y + 17
Required:
Find m<2
Solution:
m<8 + m<3 = 180 (supplementary angles and linear pair theorem)
11y + 7 + y + 17 = 180 (substitution)
Collect like terms
12y + 24 = 180
Subtract 24 from each side
12y = 180 - 24
12y = 156
Divide both sides by 12
y = 156/12
y = 13
m<2 = m<8 (alternate exterior angles are congruent)
m<2 = 11y + 7
Substitute y = 13 into the equation
m<2 = 11(13) + 7 = 143 + 7
m<2 = 150°

What is 3 2/3 minus 1 1/4
Answer: 2 5/12
3⅔ - 1¼ = 2 5/12
Because of the vertical angles and alternate interior angles we know these are similar triangles. Use what you know about proportional sides to solve for the unknown side ,x
Answer:
x = 20
Step-by-step explanation:
Length 6 corresponds to length 15
Length 8 corresponds to length x
15 ÷ 6 = 2.5
8 • 2.5 = 20
x = 20
2.5 is the scale factor of the small triangle to the big triangle.

Given g(x) = -x + 3, solve for x when g(x) = -1.
Answer:
4
Step-by-step explanation:
It's ok! This is simple. Simply plug in your given values. Since g(x) = -1, plug that into the equation.
g(x) = -x + 3
g(-1) = -(-1) + 3
=1+3
=4
Answer:
- x + 3 = - 1 ⇒ x = 4

Step-by-step explanation:
The computers of six faculty members in a certain department are to be re- placed. two of the faculty members have selected laptop machines and the other four have chosen desktop machines. suppose that only two of the se- tups can be done on a particular day, and the two computers to be set up are randomly selected from the six (implying 15 equally likely outcomes; if the com- puters are numbered 1,2,...,6, then one outcome consists of computers 1 and 2, another consists of computers 1 and 3, and so on).
(a) what is the probability that both selected setups are for laptop computers?
(b) what is the probability that both selected setups are desktop machines?
(c) what is the probability that at least one selected setup is for a desktop computer?
(d) what is the probability that at least on computer of each type is chosen for setup?
Answer:
A) The probability that both selected setups are for laptop computers is 0.067
B)The probability that both selected setups are desktop machines is 0.4
C)The probability that at least one selected setup is for a desktop computer is 0.933
D)The probability that at least on computer of each type is chosen for setup is 0.533
Step-by-step explanation:
Number of laptops = 2
Number of desktops = 4
Total number of outcomes = 15
a) what is the probability that both selected setups are for laptop computers?
Total number of outcomes = 15
So, the probability that both selected setups are for laptop computers = [tex]\frac{1}{15}=0.067[/tex]
b)what is the probability that both selected setups are desktop machines?
Number of desktops = 4
Number of desktops to be chosen = 4
We will use combination
No. of ways to select two desktops =[tex]^4C_2=\frac{4!}{2!(4-2)!}=6[/tex]
So,the probability that both selected setups are desktop machines=[tex]\frac{6}{15}=0.4[/tex]
(c) what is the probability that at least one selected setup is for a desktop computer?
P(at least 1 desktop)=1-P(No desktop)
P(at least 1 desktop)=1-P(both laptops)
P(at least 1 desktop)=1-0.067=0.933
So,the probability that at least one selected setup is for a desktop computer is 0.933
d) what is the probability that at least on computer of each type is chosen for setup?
No. of ways to select one desktop [tex]=^4C_1=\frac{4!}{1!(4-1)!}=4[/tex]
No. of ways to select one laptop =[tex]^2C_1=\frac{2!}{1!(2-1)!}=2[/tex]
So, No. of ways to select one laptop and one desktop= [tex]4 \times 2 = 8[/tex]
So,the probability that at least on computer of each type is chosen for setup=[tex]\frac{8}{15}=0.533[/tex]
In 2018, homes in East Baton Rouge (EBR) Parish sold for an average of $239,000. You take a random sample of homes in Ascension parish and find that the average home sale price was $246,000 in 2018. You test the hypothesis that the mean of the home prices from Ascension parish is higher than the EBR mean. Suppose the p-value for the test is 0.045. At the 0.10 level of significance your conclusion is:_______
A. There is evidence that the average home price of homes sold in Ascension parish in 2018 is higher than the average price of homes sold in EBR parish.
B. There is no evidence that the average home price of homes sold in Ascension parish in 2018 is higher than the average price of homes sold in EBR parish.
C. There is not enough information for decision-making.
Answer:
Option B: There is no evidence that the average home price of homes sold in Ascension parish in 2018 is higher than the average price of homes sold in EBR parish
Step-by-step explanation:
We are given;
Population mean of EBR Parish; μ1 = $239,000
Sample mean of Ascension parish; x2 = $246,000
P-value = 0.045
Population mean of Ascension parish; μ1 =?
Now,let's define the hypothesis;
Null Hypothesis; H0: μ2 = μ1
Alternative hypothesis; Ha: μ2 > μ1
Now, we are told that the level of significance is 0.1.
Thus; α = 0.1
Now,the level of significance of 0.1 is greater than the p-value which is 0.045 and thus we will fail to reject the null hypothesis and conclude that there is not enough evidence to conclude that the average home prices in Ascension parish in 2018 is higher than the average price of homes sold in EBR parish.
Carlos spends at least 45 minutes each day on the internet. Write an inequality which could be used to describe the amount of time,x, that Carlis spends on the internet.
Answer:
x ≤ 45 mins
Step-by-step explanation:
At least can be changed into less than or equal to.
Also, at most would be greater than or equal to.
Therefore, you simply need a less than or equal to sign.

Let g(x) = 2x and h(x) = x2 + 4. Evaluate (h ∘ g)(−2)
Answer:
[tex](h(g))(-2)=-32[/tex]
Step-by-step explanation:
Evaluate h ⋅ g
Replace the function designators in h ⋅ g with the actual functions.
[tex](h(g))(-2)=(x^{2} +4)(2x)[/tex]
[tex]=2x^{2}x+8x[/tex]
Multiply [tex]x^{2}[/tex] by x by adding the exponents.
[tex]=2x^{3}+8x[/tex]
Evaluate h ⋅ g at −2.
[tex]=2(-2)^{3}+8(-2)[/tex]
Simplify
[tex]=-16-16[/tex]
subtract 16 from -16
[tex](h(g))(-2)=-32[/tex]

The product of 5 and the difference of 9 and a number.
Answer: 5(9-x)
Step-by-step explanation:
Based on the question, let the number be represented by x.
From the question, we are informed that we've a product, this means that we need to multiply 5 by the difference of 9 and x.
In the order of operations, we've to multiply first before we subtract. Therefore, the equation will be written as:
= 5 × (9 - x)
= 5(9-x)

tan∧2 3Ѳ = 3, Ѳ is acute, then Ѳ is = PLEASE ANSWER FAST
Answer:
20
Step-by-step explanation:
We are given:
Tan²3Θ = 3
taking the square root of both the sides
Tan 3Θ = √3
3Θ = Arctan(√3)
the Arctan function takes a value as an input and outputs the angle at which you will have tanΘ = the input value
3Θ = 60
Θ = 20°
