Bert’s pizza contains x toppings.
Ernie’s pizza contains 4 times the number of toppings as Bert’s pizza.
The total number of toppings on the two pizzas is 15.
What is x, the number of toppings on Bert’s pizza?
Answer:
x=3
Step-by-step explanation:
x = number of toppings on berts pizza
Berts pizza has 1x toppings
Ernies pizza has 4x toppings
there are 15 toppings on both pizzas
x + 4x = 15 (combine like terms)-> 5x=15 (divide both sides by 5)-> x=3

Avery is tracking the height of a plant that grows at a constant rate. After the third week, the plant is 8.5 centimeters high. After the seventh week, the plant is 18.5 centimeters high. What was the original height, in centimeters, of the plant and how many centimeters did it grow per week?
Answer:
Original Plant was 1cm and it grew 2.5 cm per week.
Step-by-step explanation:
Using the Slope Formula (y2-y1/x2-x1)we can get how many centimeters it will grow in a week.
18.5cm-8.5cm/7-3
10cm/4
2.5 cm per week.
The original height of the plant were 1 cm and raised at rate of 2.5 cm per week.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
In 3rd week, plant height = 8.5 cm
In seventh week= 18.5 cm
So, the height in-between 4 weeks = 18.5 - 8.5 = 10
then, the height raised in one week = 10/4 = 2.25 cm
Thus, the original height of the plant were 1 cm and raised at rate of 2.5 cm per week.

Write a recursive formula for the sequence below. Use the variable "n" for your formula in your answer.
{2, -8, 32, -128, 512, ... }
Answer:
[tex]\begin{cases}a_1 = 2\\\\a_{n} = -4*a_{n-1}\end{cases}[/tex]
============================================
Explanation:
The first line of the answer says "the first term is 2".
The second line says "take any term and multiply by -4 to get the next term".
The [tex]a_n[/tex] represents the nth term while [tex]a_{n-1}[/tex] is the term just before it.
The second line shown above is the same as writing [tex]a_{n+1} = -4*a_n[/tex]
---------------
The -4 is found by dividing any term over its previous one
-8/2 = -4
32/(-8) = -4
-128/32 = -4
512/(-128) = -4
This shows the common ratio is -4 and this sequence is geometric.
The “Star Player” paradox haunts many pro athletes. For example, an NBA player may be highly rated, but their statistics don’t quite match up. For example, Lebron James in 2015 made 293 shots “outside the paint” (i.e., not under the basket). But his basket-scoring percentage this year when shooting at these distances was a dismal 34%. Roughly, how many of these baskets did he make?

Use elimination to determine which ordered pair is the solution to the system of equations below. Use the space below to show all steps (by typing the steps) in order, then choose the correct answer. You can write the solution as an ordered pair or write the letter of the correct answer. All work must support the answer that you choose. -2x - 14 = 10 2x + 2y = 14
Answer:
in the ordered pair; ( x = 27/4 , y = 1/4 )
Step-by-step explanation:
Given that:
The system of the equation shown below is:
-2x - 14y = 10
2x + 2y = 14
We are to use the elimination method to determine the ordered pair.
From the above equation:
-2x - 14y = 10 --- (1)
2x + 2y = 14 --- (2)
Add both equation 1 and 2 together in order to eliminate x, then we can solve for y first.
-2x - 14y = 10
2x + 2y = 14
0 - 16y = -4
- 16 y = - 4
divide both sides by - 16, Then:
-16y /-16 = -4/-16
y = 1/4
Since y = 1/4, Then from equation (2), x will be :
2x + 2y = 14
2x + 2(1/4) = 14
2x + 1/2 = 14
2x = 14 - 1/2
2x = 13.5
x = 13.5/2
x = 27/4
Thus, in the ordered pair; ( x = 27/4 , y = 1/4 )

Answer:
x = ± 4
y = - 2
Step-by-step explanation:
y = 0.5x² - 10 ------------------------(I)
y = -x² + 14 ------------------------(II)
Substitute the y value in equation (II)
0.5x² - 10 = -x² + 14 {Add x² to both sides}
0.5x² + x² -10 = 14 {combine like terms}
1.5x² - 10 = 14 {Add 10 to both sides}
1.5x² = 14 + 10
1.5x² = 24 {Divide both sides by 1.5}
1.5x²/1.5 = 24/1.5
x² = 16
x = ±4
Substitute x = 4 in (I)
y = 0.5 * 4² - 10
= 0.5*16 - 10
= 8- 10
y = -2
Substitute x = -4 in (I)
y = 0.5 * (-4)² - 10
= 0.5*16 - 10
= 8- 10
y = -2
- 4x + 9y = 9
-8x + 10y = 10
Answer:
y = 1, x = 0
Step-by-step explanation:
multiply -4x +9y = 9 by -2 to get 8x -18y = -18
combine the two equations to get -8y = -8
divide both sides by -8 to get y = 1
plug in 1 as the y into one of the equations and solve to get x = 0
Answer:
(0,1)
x = 0
y = 1
Step-by-step explanation:
(-4x + 9y = 9)-8
(-8x + 10y = 10)4
32x - 72y = -72
-32x + 40y = 40
-32y = -32
y= -32/-32
y=1
-4x + 9(1) = 9
-4x + 9 = 9
-4x = -9 + 9
-4x = 0
x = 0/-4
x = 0

The probability distribution of the random variable X represents the number of hits a baseball player obtained in a game for the 2012 baseball season. x 0 1 2 3 4 5 Upper P (x )0.1664 0.3302 0.2933 0.1485 0.0369 0.0247 The probability distribution was used along with statistical software to simulate 25 repetitions of the experiment (25 games). The number of hits was recorded. Approximate the mean and standard deviation of the random variable X based on the simulation. The simulation was repeated by performing 50 repetitions of the experiment. Approximate the mean and standard deviation of the random variable. Compare your results to the theoretical mean and standard deviation. What property is being illustrated?
The table below shows the number of hits for 25 and 50 repetitions.
Answer and Step-by-step explanation: Expected Value or Mean of a probability distribution is calculated as:
E(X) = μ = ∑xP(X)
In a game for the 2012 baseball season, expected value is:
[tex]\mu=0(0.1670)+1(0.3320)+2(0.2864)+3(0.1499)+4(0.0381)+5(0.0266)[/tex]
μ = 1.640
Standard Deviation (σ) of a probability distribution is:
[tex]\sigma=\sqrt{\Sigma (x-\mu)^{2}P(X)}[/tex]
[tex]\sigma = \sqrt{(0-1.640)^{2}(0.1670)+...+(5-1.640)^{2}(0.0266)}[/tex]
σ = 1.1883
The simulate experiment of 25 repetitions shows a table. With this table, it is possible to create a frequency table as follows:
x | f
0 | 4
1 | 7
2 | 11
3 | 2
4 | 1
With a frequency table, expected value is calculated as:
[tex]\mu=\frac{\Sigma (fx)}{\Sigma f}[/tex]
[tex]\mu=\frac{0*4+1*7+2*11+3*2+4*1}{25}[/tex]
μ = 1.56
Standard deviation, using a frequency table, is calculated as:
[tex]\sigma = \sqrt{\frac{n\Sigma (fx^{2})-(\Sigma fx)^{2}}{n(n-1)} }[/tex]
[tex]\sigma=\sqrt{\frac{25(0*4^{2}+...+4*1^{2})-(0*4+...+4*1)^{2}}{25(24)} }[/tex]
σ = 0.983
The same can be done for 50 repetitions.
The frequency table is
x | f
0 | 6
1 | 18
2 | 16
3 | 9
4 | 1
[tex]\mu=\frac{0*6+1*18+2*16+3*9+4*1}{50}[/tex]
μ = 1.62
[tex]\sigma=\sqrt{\frac{50(0*6^{2}+...+4*1^{2})-(0*6+...4*1)^{2}}{50(49)} }[/tex]
σ = 0.9775
Comparing expected values and standard deviations, observe that the bigger the repetition of the experiment, mean and standard deviation get closer to the theoretical statistical values. This is an example of the Law of Large Numbers, a theorem stating as the number of random, normally distributed values increase, their sample mean approaches the theoretical mean.
