Jeriel has a points card for a movie theater.

He receives 75 rewards points just for signing up.

He earns 2.5 points for each visit to the movie theater.

He needs 90 points for a free movie ticket.

Answer: 2.5

Step-by-step explanation: subtract 2x from both sides and get 4x-2=8 so then add 2 on both sides to get 4x=10 and last step is to divide both sides by 4 which wild get you x=2.5

Answer:

The answer is D 10.50x =300.000

Step-by-step explanation:

I figured this out by knowing that to find the time you need to divide the total by the given made per hour which is 10.50 and he would make a total of $300 after about 28 hours so it would be 10.50 x being 28 = 300 dollars which gives the equation 10.50x = 300.000

If the columns of matrix B are linearly dependent, then the columns of AB are also linearly dependent.

Suppose the columns of matrix B are linearly dependent, which means there exist constants c₁, c₂, ..., cₙ (not all zero) such that c₁b₁ + c₂b₂ + ... + cₙbₙ = 0, where b₁, b₂, ..., bₙ are the columns of B.

Now, let's consider the product AB. Suppose A is an m × n matrix.

The jth column of AB is given by the product AB(:, j) = A(b₁j) + A(b₂j) + ... + A(bₙj), where b₁j, b₂j, ..., bₙj are the jth columns of B.

Substituting the linear dependence relation for the columns of B into the expression for AB(:, j), we get:

AB(:, j) = A(c₁b₁ + c₂b₂ + ... + cₙbₙ)

         = c₁A(b₁) + c₂A(b₂) + ... + cₙA(bₙ)

Since matrix multiplication distributes over column vectors, we have:

AB(:, j) = c₁A(b₁) + c₂A(b₂) + ... + cₙA(bₙ)

This shows that the jth column of AB can be expressed as a linear combination of the columns of A, multiplied by the corresponding coefficients c₁, c₂, ..., cₙ. Therefore, if the columns of B are linearly dependent, the columns of AB are also linearly dependent.

In conclusion, if the columns of matrix B are linearly dependent, then so are the columns of the product AB.

Because b > 1, the correct response in this situation would be: "1.022 is the growth factor for the GDP since 1950, and the GDP increases by a factor of 1.022 every year."

In this instance, we're assuming that we can use the following function to simulate the US GDP, or gross domestic product, in dollars:

\(GDP = 11(1.0220)^{t}\)

We can also see that the exponential model formula given by: governs this formula.

\(GDP = 11(1.0220)^{t\)

Where a denotes the starting sum, b the model's growth/decay rate, and t is the number of years since 1950.

The value of b in this instance is provided by:

b = 1.022

And when we calculated r as the growth rate, we obtained:

1.022 = 1 + r

r = 1.022 - 1

r = 0.022

Because b > 1, the correct response in this situation would be: "1.022 is the growth factor for the GDP since 1950, and the GDP increases by a factor of 1.022 every year."

The equation that represents the relationship between the total number of hours and days is h = 8d.

A straight line on a coordinate plane is described by a linear equation. It has the mathematical formula y = mx + b, where m denotes the line's slope and b its y-intercept. The largest power of the variable (in this example, y) in a linear equation with degree 1 is 1.

Given that, total number of hour the chef spends making cakes, h, and the number of days chef spends making cakes, d.

Thus, Total number of hours = (Number of cakes per day) x (Number of hours per cake) x (Number of days)

h = 4 x 2 x d

h = 8d

Here is the equation that was provided: g(x) = −2(x + 3)² − 7. This is the parent function equation: f(x) = x²When we compare the parent function to the function given, we can observe the following changes: In order to compare the two functions and see the changes, it is better to express the parent function in the form: a*f(b(x-h)) + k. Here, f(x) = x² , a=1, h=0, b=1, k=0So, parent function in this form: f(x) = 1*f(1*(x-0))+0f(x) = x². The transformed function in this form: g(x) = -2*f(1*(x+3)) - 7g(x) = -2(x+3)² - 7.

In general, when dealing with probability, it is important to consider the context and any relevant information before making any conclusions or decisions based on the probabilities.

Probability is a measure of the likelihood or chance that a particular event will occur. It is a mathematical concept used in statistics, mathematics, and science to help predict the outcome of experiments or events based on data and past experience. The probability of an event is expressed as a number between 0 and 1, where 0 means that the event is impossible, and 1 means that the event is certain to occur.

Here,

However, here are a few possible statements that could be true:

If the spinner has only two colors, pink and green, then the probability of landing on pink is 18/100 or 9/50.

If the spinner has more than two colors, and pink is one of them, then the probability of landing on pink may or may not be high, depending on the number of colors and their respective probabilities.

If the spinner is biased or weighted, then the probability of landing on pink may not be exactly 18/100, and may be influenced by external factors such as the force of the spin or the design of the spinner.

Since MA ≠ TH, hence MATH is not a rectangle

Step-by-step explanation:

To prove that quadrilateral MATH, M (-4,-1) A(-3,2). T(3,0), H(2-3) is a rectangle, we need to get the length of each sides and show that MA =TH and MH = TA

For MA:

M (-4,-1) A(-3,2)

MA = √(2+1)²+(3+4)²

MA = √(3)²+(7)²

MA = √9+49

MA =√58

For TH:

T(3,0), H(2-3)

TH = √(-3-0)²+(2-3)²

TH = √(-3)²+(-1)²

TH = √9+1

TH =√10

For TH:

M(-4,-1), H(2-3)

MH = √(-3+1)²+(2+4)²

MH = √(-2)²+(6)²

MH = √4+36

MH =√40

For TA:

T(3,0), A(-3,2)

TA = √(2-0)²+(-3-3)²

TA = √(2)²+(-6)²

TA = √4+36

TA =√40

Since MA ≠ TH, hence MATH is not a rectangle

The population decreased by 5,400 people from 2015 to 2020.

Also known as population decline, means the reduction in a human population size

Population in 2015 = Population in 2010 + Growth from 2010 to 2015

Population in 2015 = 167,000 + (8% of 167,000)

Population in 2015 = 167,000 + 13,360

Population in 2015 = 180,360

Population in 2020 = Population in 2015 - Decrease from 2015 to 2020

Population in 2020 = 180,360 - (3% of 180,360)

Population in 2020 = 180,360 - 5,411.8

Population in 2020 = 174,948.2

The population decrease from 2015 to 2020 is:

= Population in 2015 - Population in 2020

= 180,360 - 174,948.2

= 5,411.8

1. It is not unusual for Joe to roll a four twice in six attempts because a die has 6 sides, so the probability of rolling a four is 1/6 (one in six).

2. If Joe rolled a four three times in six attempts, it would still not be considered unusual because when the probability of rolling a four three times is slightly lower than rolling it twice, it is still not considered a very low probability or unusual occurrence.

It is not unusual for Joe to roll a four twice in six attempts. Here's why:
1. A die has 6 sides, so the probability of rolling a four is 1/6 (one in six).
2. When rolling the die six times, the probability of rolling a four twice can be calculated using the binomial probability

formula:\(P(X=k) = (nCk) * (p^k) * (q^(n-k)),\)

where n is the number of trials,

k is the number of successful outcomes,

p is the probability of success, and q is the probability of failure (1-p).
3. In this case, n=6, k=2, p=1/6, and q=5/6.

So, \(P(X=2) = (6C2) * (1/6)^2 * (5/6)^4\) ≈ 0.2009 or 20.09%.
4. Since 20.09% is not a low probability, it is not unusual for Joe to roll a four twice in six attempts.
If Joe rolled a four three times in six attempts, it would still not be considered unusual. Here's why:
1. Using the same binomial probability formula as before, we now have k=3.
2. \(P(X=3) = (6C3) * (1/6)^3 * (5/6)^3\) ≈ 0.1550 or 15.50%.
3. While the probability of rolling a four three times is slightly lower than rolling it twice, it is still not considered a very low probability or unusual occurrence.

Answer:

Step-by-step explanation:

We know that a rhombus is a quadrilateral with four sides. All four sides have the same length.

From the diagram, it is clear that

As all the four sides of the rhombus have equal length.

So we can observe

\(VW=WX\)

\(6m-12 = 4m+4\)

Add 12 to both sides

\(6m-12+12=4m+4+12\)

\(6m=4m+16\)

\(2m=16\)

Divide both sides by 2

\(\frac{2m}{2}=\frac{16}{2}\)

\(m=8\)

so

The length of VW= 6m-12

                             = 6(8)-12  ∵ \(m=8\)

                              = 48-12

                              = 36

Thereofore, the length of VW = 36 units.
