<3
Answer:
1. True
2. True
Step-by-step explanation:
So we are playing with variables here, lets look at 1.
5x + 9 = 29 if x = 4
This means that if x equals 4, would it make the equation true? Let's find out :
Substitute :
5(4) + 9 = 29
20 + 9 = 29
This is true, let's do the same for 2. :
7x - 8 = 13 if x = 3
7(3) - 8 = 13
21 - 8 = 13
This is also true.

State sales tax S is directly proportional to retail price p . An item that sells for 172 dollars has a sales tax of 12.32 dollars. Find a mathematical model that gives the amount of sales tax S in terms of the retail price p . Function: S ( p )
Answers
Answer:
[tex]s(p) =\frac{77p}{1075}[/tex]
Step-by-step explanation:
Given
s = sales tax
p = retail price
The variation is represented as:
[tex]s\ \alpha\ p[/tex]
s = 12.32 when p = 172.
Required: Determine function s(p)
[tex]s\ \alpha\ p[/tex]
Convert to equation
[tex]s = kp[/tex]
Where k is the constant of variation.
Make k the subject
[tex]k =\frac{s}{p}[/tex]
Substitute values for s and p
[tex]k =\frac{12.32}{172}[/tex]
Multiply by 100/200
[tex]k = \frac{1232}{17200}[/tex]
Simplify:
[tex]k =\frac{77}{1075}[/tex]
To get the function, we substitute 77/1075 for k in:[tex]s = kp[/tex]
[tex]s =\frac{77}{1075}p[/tex]
[tex]s =\frac{77p}{1075}[/tex]
Express as a function
[tex]s(p) =\frac{77p}{1075}[/tex]
A large operator of timeshare complexes requires anyone interested in making a purchase to first visit the site of interest.

In addition, 10% of day visitors ultimately make a purchase, 25% of night visitors make a purchase, and 20% of those visiting for two nights make a purchase. Suppose a visitor is randomly selected. What is the probability that the visitor makes a purchase
Answers
Answer:
0.1575 = 15.75% probability that the visitor makes a purchase
Step-by-step explanation:
We have these following probabilities:
55% probability that a visitor selects a day visit, and in this case, 10% probability of making a purchase.
25% probability that a visitor chooses a one-night visit, and in this case, 25% probability of making a purchase.
20% probability that a visitor chooses for a two night visit, and in this case, 20% probability of making a purchase.
What is the probability that the visitor makes a purchase
[tex]p = 0.55*0.1 + 0.25*0.25 + 0.2*0.2 = 0.1575[/tex]
0.1575 = 15.75% probability that the visitor makes a purchase

It is reported that 50% of all computer chips produced are defective. Inspec- tion ensures that only 5% of the chips legally marketed are defective. Unfortunately, some chips are stolen before inspection. If 1% of all chips on the market are stolen, find the probability that a given chip is stolen given that it is defective.
Answers
The required, probability that a given chip is stolen given that it is defective is approximately 0.019, or 1.9%.
To find the probability that a given chip is stolen given that it is defective, we can use Bayes' theorem. Bayes' theorem allows us to update the probability of an event based on new information.
Let's define the events:
A: A chip is stolen.
B: A chip is defective.
We are given the following probabilities:
P(B) = 0.50 (50% of all computer chips produced are defective).
P(B'|A) = 0.05 (inspection ensures that only 5% of the chips legally marketed are defective, which means 95% are not defective).
P(A) = 0.01 (1% of all chips on the market are stolen).
We want to find P(A|B), which is the probability that a given chip is stolen, given that it is defective.
Bayes' theorem states:
P(A|B) = (P(B|A) * P(A)) / P(B)
We can calculate P(B|A) as follows:
P(B|A) = 1 - P(B'|A) = 1 - 0.05 = 0.95
Now, let's plug the values into Bayes' theorem:
P(A|B) = (P(B|A) * P(A)) / P(B)
P(A|B) = (0.95 * 0.01) / 0.50
P(A|B) = 0.019
Therefore, the probability that a given chip is stolen given that it is defective is approximately 0.019, or 1.9%.

Ingredients for 7 cakes
49 g sugar

63 ml milk
Here is a list of ingredients for 7 cakes. Aaron makes some cakes. He uses 50g of flour. How many cakes did he make?
Answers
Answer:
He made 5 cakes
Step-by-step explanation:
49 divided by 7 = 7
56 divided by 7 = 8
70 divided by 7 = 10
63 divided by 7 = 9
So for one cake you would need 7 g sugar, 8 g butter, 10 g flour, and 9 ml milk. So, 50 divided by 10 = 5 cakes

What is the x intercept of the graph of the inequality 2x + 3y > 12
Answers
Answer: x intercept = 6
This is the location (6,0)
===============================================================
Explanation:
I assume you're talking about the boundary line of the inequality. The boundary line equation is 2x + 3y = 12
To find the x intercept, plug in y = 0 and solve for x
2x + 3y = 12
2x + 3(0) = 12
2x = 12
x = 12/2
x = 6
The boundary line 2x+3y = 12 crosses the x axis at x = 6.
We can say the x intercept is x = 6. This is the location (6,0).
Side note: the y intercept is y = 4, which is found by plugging in x = 0 and solving for y.

Each cube inside the rectangular prism has an edge length of inch. What is the volume of
the rectangular prism?
256 in.
81 in
3 in
9 in.
Answers
Answer:
Step-by-step explanation:
length = 6 x 1/3 = 2 inches
width = 4 x 1/3 = 4/3 inches
height = 8 x 1/3 = 8/3 inches
volume = lwh = 2 x 4/3 x 8/3 = 64/9 cubic inches
Another approach is the following:
There are 6 x 4 x 8 = 192 cubes inside the prism,
Each cube has a volume of 1/27 cubic inches.
Therefore total volume = 192 x 1/27 = 192/27 = 9

A man wishes to keep some money in savings de-
posit at 25% compound interest so that after 3
years he can buy a car for N150000. How much
does he need to deposit now?
Answers
Answer:
He needs to deposit N76800 now.
Step-by-step explanation:
The amount of money is compound interest after t years is given by:
[tex]P(t) = P(0)(1+r)^t[/tex]
In which P(0) is the initial amount of money invested and r is the interest rate, as a decimal.
25% compound interest so that after 3 years to buy a car for N150000.
This means that:
[tex]t = 3, P(t) = 150000, r = 0.25[/tex]. So
[tex]P(t) = P(0)(1+r)^t[/tex]
[tex]P(t) = P(0)(1+0.25)^t[/tex]
[tex]P(t) = P(0)(1.25)^t[/tex]
[tex]150000 = P(0)(1.25)^3[/tex]
[tex]P(0) = \frac{150000}{(1.25)^3}[/tex]
[tex]P(0) = 76800[/tex]
He needs to deposit N76800 now.
