The game with 8 minutes of time-outs is 98 minutes long.

What is an algebraic expression?

An algebraic expression is a mathematical phrase that can contain numbers, variables, and operations such as addition, subtraction, multiplication, and division.

In this case, the algebraic expression that represents the length of the soccer game would be:

m = 90 + x

where m represents the total length of the game in minutes, 90 represents the fixed length of the game, and x represents the variable length of time-outs in minutes.

To find the length of the game with 8 minutes of time-outs, we substitute x = 8 into the expression:

m = 90 + 8 = 98

Therefore, the game with 8 minutes of time-outs is 98 minutes long.

The value of p such that the matrix M does not have an inverse is given as follows:

p = -5.

The matrix M for this problem is given as follows:

M = [7 2

       p -1].

As it is a 2 x 2 matrix, the determinant is obtained with the multiplication of principal diagonal subtracted by the multiplication of the secondary diagonal, hence:

|M| = -7 - 2p.

The matrix does not have an inverse if the determinant assumes a value of zero, hence the value of p is obtained as follows:

-7 - 2p = 0

2p = -7

p = -7/2

The solution is, the retail price of the mattress, before the discount is $2,400. & the wholesale price, before the markup was $960

A percentage is a number or ratio that can be expressed as a fraction of 100. A percentage is a number or ratio expressed as a fraction of 100. It is often denoted using the percent sign, "%", although the abbreviations "pct.", "pct" and sometimes "pc" are also used. A percentage is a dimensionless number; it has no unit of measurement.

here, we have,

Part A:

Given that the mattress is sold for 50% off of the retail price, let the retail price of the mattress be x, then

50% of x = 1200

⇒ 0.5x = 1200

⇒ x = 1200 / 0.5 = 2400

Therefore, the retail price of the mattress, before the discount is $2,400.

Part B:

Given that the store marks up the retail price to 150% of the wholesale price. Let the whole sale price be p, then

(100% + 150%) of p = 2400

250% of p = 2400

2.5p = 2400

p = 2400 / 2.5 = 960.

Therefore, the wholesale price, before the markup was $960.

Represent the number with n

So, we have

Lacey = 10 * (n/10 + 1/2)

Euan = 100 * (n/100 + 1/2).

Also, Lacey's new number is 3/4 of Euan's new number, so we have:

10 * (n/10 + 1/2) = (3/4) * (100 * (n/100 + 1/2))

Solving for n, we have:

100 * (n/100 + 1/2) = (4/3) * (10 * (n/10 + 1/2))

Divide through by 100

n/100 + 1/2 = (4/30) * (n/10 + 1/2)

Evaluate

(n + 50)/100 = 4n/300 + 2/30

Yes, it would be unusual to get a score of 0 on a binomial distribution with a mean of 2.5 and a standard deviation of 1.4. This is because the expected value of such a distribution is much higher than 0. The binomial distribution is a type of probability distribution which is used to describe the probability of a discrete event occurring a certain number of times in a given number of trials. The mean of the binomial distribution is the expected value of the events, while the standard deviation is a measure of how much the values of the events vary from the expected value. In this case, the expected value is 2.5, and the standard deviation is 1.4. This means that the probability of getting a score of 0 is quite low, since the expected value is so much higher than 0. Therefore, it would be considered unusual to get a score of 0 on this binomial distribution.

So, the value of 5 + x - y would be 14 if x-y=9 is a true equation.

The financial planner invested $4,737.50 in the mini-mall development plan and $1,012.50 in the savings account.

The amount invested in the savings account is equal to the total amount invested minus the amount invested in the mini-mall development plan. We can express this as an equation:

Total Investment - Investment in Mini-Mall Development Plan = Investment in Savings Account

Substituting the values given in the problem, we get:

$5,750 - Investment in Mini-Mall Development Plan = Investment in Savings Account

To solve for the Investment in Mini-Mall Development Plan, we need to use the combined interest earned for the first year. We can express this as an equation:

Interest Earned = (Investment in Savings Account x Interest Rate) + (Investment in Mini-Mall Development Plan x Interest Rate)

Substituting the values given in the problem, we get:

$475 = (Investment in Savings Account x 0.02) + (Investment in Mini-Mall Development Plan x 0.12)

Solving for Investment in Mini-Mall Development Plan, we get:

Investment in Mini-Mall Development Plan = ($475 - (Investment in Savings Account x 0.02))/0.12

Substituting the values given in the problem, we get:

Investment in Mini-Mall Development Plan = ($475 - ($5,750 - Investment in Mini-Mall Development Plan x 0.02))/0.12

Solving for Investment in Mini-Mall Development Plan, we get:

The four possible times that car B could take to complete one lap are: 120 seconds, 90 seconds, 60 seconds, and 30 seconds.

The equation used to solve this problem is (150 - 30) = N * B, where N is the number of laps and B is the total number of seconds for car B to complete one lap. Therefore, the four possible times for car B to complete one lap are 120 seconds, 90 seconds, 60 seconds, and 30 seconds.

When solving for the total time, it is important to remember that the two cars start the race together and that their speeds remain constant. This means that the time it takes for car B to complete one lap must be a factor of 150 seconds. If car B takes a time that is not a factor of 150, then it will not be able to finish the race in 150 seconds.

If a line parallel to one side of a triangle intersects the other two sides, then this line divides those two sides proportionally.

Let x be the distance between 1st Street and 2nd Street along Pike Avenue.

As 1st Street and 2nd Street are parallel we can use the Side Splitter Theorem to calculate x:

[tex]\implies \sf x:300=40:40+160[/tex]

[tex]\implies \sf x:300=40:200[/tex]

[tex]\implies \sf \dfrac{x}{300}=\dfrac{40}{200}[/tex]

[tex]\implies \sf x=\dfrac{40}{200} \cdot 300[/tex]

[tex]\implies \sf x=60\; ft[/tex]

To calculate the distance between 2nd Street and the landmark along Pike Avenue, subtract the found distance between 1st Street and 2nd Street along Pike Avenue from the length of Pike Avenue:

The required value of angle x for a given hexagon is 20°.

What is a hexagon?

In terms of geometry, a hexagon is a closed, six-sided polygon in two dimensions. Six vertices and six angles make up a hexagon. The words "hexa" and "gonio" both refer to six.

A hexagon's internal angles add up to 720°. All of the sides and interior angles of a regular hexagon are the same lengths.

Given, the interior angles of a hexagon are 7x°, 7x°, 4x°, 7x°, 7x°, and 4x° respectively.

So, the sum of interior angles = 720°

or, 7x° + 7x° + 4x° + 7x° + 7x° + 4x° = 720°

or, 36x° = 720°

or, x = 720/36

The code is: dbinom(3:5, size=4, prob=0.25) which yields an answer of 0.3125. This means that the probability of 3 to 5 bicycle accidents occurring in the next four months is 0.3125.

The equation for the probability of a certain number of bicycle accidents occurring in the next four months is [tex]P(x) = (x^3 - 3x^2 + 5x - 3)/24[/tex], where x is the number of accidents. To solve this equation with R, we can use the dbinom() function which is used to calculate the binomial cumulative distribution function. We set the size parameter to 4 (the number of months) and the probability parameter to 0.25 (the probability of a bicycle accident occurring at the intersection in a single month). The code is dbinom(3:5, size=4, prob=0.25). This yields an answer of 0.3125, meaning that the probability of 3 to 5 bicycle accidents occurring in the next four months is 0.3125.
