Answer:
p₁ = 0.98 p₀
p₂ = 0.98 p₁
Step-by-step explanation:
Given - N 2008 price of houses were declining by 2% each year.
If a house was purchased for $195,000.
To find - Write the equation that models the situation.
Proof -
Let us assume that
p₀ = initial price of house
p₁ = price of house after 1 year
p₂ = price of house after 2 years
Now,
Given that, p₀ = $195,000
Then,
p₁ = p₀ - 2% p₀
= p₀( 1 - 2%)
= p₀ ( 98%)
⇒p₁ = 98% p₀
⇒p₁ = [tex]\frac{98}{100}[/tex] p₀
⇒p₁ = 0.98 p₀
Now,
Also p₂ = p₁ - 2% p₁
By doing the same process as above, we get
p₂ = 0.98 p₁

What is an equation for the line that passes through points (2.-3) and (1, 2)? (+ 3) = -5(x - 2) b. (y - 3) = 5(x ! 2) (y - 3) = -5(.x + 2) d. (+3) = S(x - 2)
Answer:
A. y + 3 = -5(x - 2)
Step-by-step explanation:
The slope is:
2 - (-3) / 1 - 2 = 5 / -1 = -5.
Then, put it in point slope form (which was [tex](y - y1) = m(x-x1)[/tex] where m is the slope, and (x1, y1) is the coordinate point it gives you. You can use m = -5, x1 = 2 and y1 = -3.)
y + 3 = -5(x - 2)

Marcy is baking blueberry pies to sell at her bakery. She starts with 8 3/4 cartons of blueberries, of which she uses 1/2 for the first batch of pies. How many cartons of blueberries does Marcy use for the first batch of pies?
Answer: Marcy used [tex]\dfrac{35}8[/tex] cartons of blueberries for the first batch of pies.
Step-by-step explanation:
Given: Quantities of blueberries = [tex]8\dfrac34[/tex] cartons
[tex]=\dfrac{8\times4+3}{4}=\dfrac{35}{4}[/tex] cartons
Blueberries used for first batch = [tex]\dfrac12[/tex] of (Total)
[tex]=\dfrac12\times\dfrac{35}{4}\\\\=\dfrac{35}{8}[/tex]cartons
Hence, Marcy used [tex]\dfrac{35}8[/tex] cartons of blueberries for the first batch of pies.
Use the given information to write the equation of a line.
slope = -2 and passes through through (1,1)
Answer:
y = -2x - 1
Step-by-step explanation:
If you already know the slope. Just find out the y-intercept. Plug the coordinates into the equation.
y = mx + b
y = -2x + b
1 = -2(1) + b
1 = -2 + b
-1 = b

A recent increase in sales of microchips has forced a computer company to buy a new processing machine to help keep up with demand. The builders of the new machine claim that it produces fewer defective microchips than the older machine. From a random sample of 90 microchips produced on the old machine, 5 were found to be defective. From a random sample of 83 microchips produced on the new machine, 3 were found to be defective. The quality control manager wants to construct a confidence interval to estimate the difference between the proportion of defective microchips from the older machine and the proportion of defective microchips from the new machine.
The final question is;
Why is it not appropriate to calculate a two-sample z-interval for a difference in proportions?
Answer:
The normality of the sampling distribution of the difference in sample proportions cannot be established.
Step-by-step explanation:
To use the two-sample z-interval for a difference in proportions, some conditions must be met which help us to know the normality of the distribution.
The conditions are;
- The method of sampling for each population must be simple random sampling.
- The samples must be independent.
- Each sample must include at least 10 successes and 10 failures.
- Each population must be a minimum 20 times its sample.
In this case, we are not given the population size and as such we cannot ascertain the last condition I wrote above since the sample proportion we are given alone isn't sufficient. Also, they both don't include at least 10 failures. Thus the normality of the sample proportions cannot be established.
Answer: the normality of the sampling distribution of the difference in sample proportions cannot be established

Answer:
C
Step-by-step explanation:
Given
p + 15 = 4 ( isolate p by subtracting 15 from both sides )
p = - 11 → C
Answer:
p -11 + 15 = 4

Valley Mills Sports Center has a total of 318 footballs and basketballs. There are 76 more footballs for sale than basketballs.
How many footballs are for sale?
A. 121
B. 176
C. 197
D. 242
The number of footballs that are for sales when its known that there are total 318 footballs and basketballs and there are 76 more footballs for sale than basketballs, is given by: Option C: 197
How to form mathematical expression from the given description?You can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.
Given that:
Total number of basketballs and footballs in the considered sports center = 318 (assuming they're for sales, as rest of the question is talking about footballs and basketballs being for sales)Number of footballs = 76 + Number of basketballsAssume that:
Number of footballs = xNumber of basketballs = yThen we get two equations, as:
[tex]x+y = 318\\x = 76 + y[/tex]
Substituting the variable x in first equation by the expression obtained in second equation for x, we get:
[tex]x + y = 318\\(76 + y) + y = 318\\76 + 2y = 318\\\text{Subtracting 76 from both the sides}\\\\2y = 318 - 76 = 242\\\\\\2y = 242\\\\\text{Dividing both the sides by 2}\\\\y = \dfrac{242}{2} = 121[/tex]
Thus, we got: Number of basketballs = y = 121
Using this result and the first equation, we get:
[tex]x + 121 = 318\\x = 318 - 121 = 197[/tex] = number of footballs.
Thus, the number of footballs that are for sales when its known that there are total 318 footballs and basketballs and there are 76 more footballs for sale than basketballs, is given by: Option C: 197

Gilberto's family traveled 2 7 of the distance to his grandmother's house on Saturday. They traveled 4 5 of the remaining distance on Sunday. What fraction of the total distance to his grandmother's house was traveled on Sunday?
Answer:
the fraction of the total distance traveled on the sunday is [tex]\frac{4}{7}[/tex]
Step-by-step explanation:
The computation of the fraction of the total distance traveled on the sunday is given below:
[tex]= 1 - \frac{2}{7} \times \frac{4}{5}\\\\= \frac{5}{7} \times \frac{4}{5}\\\\= \frac{4}{7}[/tex]
Hence, the fraction of the total distance traveled on the sunday is [tex]\frac{4}{7}[/tex]
We simply multiplied the two fractions

First Parenthesis then exponents; however in the parenthesis we have an exponent so first we do the exponent and then the addition.
4^4 x (6^3 + 56) = ?
4^4 x (216 + 56)
4^4 x (272) = ?
then we do the exponents and after that multiply
