The inequality would be 15 ≤ t ≤ 19 showing the range of possible minutes it will take for the taxi to get to Claire's house.

Inequality is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are not equal.

The time could vary by as much as 4 minutes.

Let t be the range of possible minutes

The taxi service says it will take 15 minutes to get to her house based on normal traffic routines.

So the inequality as 15 ≤ t

The time could vary by as much as 4 minutes.

So the inequality as 15 ≤ t ≤ 15 + 4

⇒  15 ≤ t ≤ 19

Therefore, the inequality would be 15 ≤ t ≤ 19 showing the range of possible minutes.

Answer:

(3,13 ) & (-1,5)

Step-by-step explanation:

a. 2x + 7 = x^2 + 4

b. move all terms to the left side and set equal to zero. then set each factor equal to zero. which gives you the x values 3, -1

c. substitute x with the x values to get y.  2(3) + 7 = -1^2 + 4

d. the solution is (3,13 ) & (-1,5)

The equation of the line is y = -2.5x - 1

The table represents the given parameter

On the table, we have the following points

Point, (x, y) = (0, -1) and (2, -6)

So, we start by calculating the slope of the line using the following slope equation

Slope = (y₂ - y₁)/(x₂ - x₁)

Where x and y are defined above

So, we have

Slope = (-6 + 1)/(2 - 0)

Evaluate

Slope = -2.5

The equation of the line is then calculated as

y = m(x - x₁) +y₁

Where

Slope, m = -2.5

(x₁, y₁) = (0, -1)

So, we have

y = -2.5(x + 0) - 1

Open the brackets and evaluate

y = -2.5x - 1

Hence, the line has an equation of y = -2.5x - 1

Given:

One variety of gift wrappers sells for 50 cents a sheet the other for 25 cents a sheet.

In dollars,

One variety of gift wrappers sells for 0.5 dollars a sheet the other for 0.25 dollars a sheet.

The assortment will cost $7.

Let x be the number of 50 cents sheets.

Let y be the number of 25 cents sheets.

It is also given that,

The number of 50 cents sheets is 3 times the number of 25 cent sheets.

x=3y ........ (1)

0.5x+0.25y=7 ....... (2)

Substitute (1) in (2) we get,

Hence, x=3(4)

x=12

So, the number 50 cents sheets are 12 and the number of 25 cents sheet is 4.

Part I

In factored form, [tex]f(x)=a(x-2)(x-3)(x+1)[/tex]. Substituting x=1,

[tex]f(1)=32=a(1-2)(1-3)(1+1)\\\\\implies 32=4a\\\\a=8\\\\\therefore f(x)=8(x-2)(x-3)(x+1)[/tex]

[tex]f(3)=-24=a(3-5)(3-2)(3-4)\\\\\implies 24=2a\\\\a=12\\\\\therefore f(x)=12(x-5)(x-2)(x-4)[/tex]

Answer:

.1

We have 20 marbles.

Probability of blue marble = 8/20 = .4

Since the blue marble is put back, we still have 20 marbles.

Probability of green marble = 5/20 = .25

Multiplying these probabilities:

.4 × .25 = .1

The appropriate measures of central location for interval data are Mode, median, and average

The measure of a data set's most valuable position is its core location. Basically, they are mean, median, and mode.

Mean: The mean is the data set's average value. It is the total number of data divided by the sum of the data set.

The data point in the middle of the data collection is known as the median.

It can be obtained by halving the data set, which will show where the median is located.

Simply put, mode refers to the data that occurs most frequently.

Each of these provides positional information on the data, as can be seen from the definition.

The one value that other values in the data center around is given by the mean.

Therefore, the correct options are Mode, median, and average

‘B’ had a better college entrance exam score due to the higher value of Z-Score.

The Z-score of an observation is the number of standard deviations it falls above or below the mean. Standard deviation is a statistic that is used to measure the dispersion of a dataset relative to its mean and is calculated by doing the square root of the variance.

[tex]Z=\frac{(observation-mean)}{standard deviation}[/tex]

By putting the values as given in the question,We get,

A's score is (600 - 500) / 200 = 0.5 standard deviation i.e. above the mean.

B's score is (25 - 20) / 5 = 1 standard deviations i.e. above the mean.

2.  0.425  is the probability that the airline will not have enough seats for all the ticket holders who show for the flight.

P(airline will not have enough seats for all the ticket holders who show for the flight) = P(more than 267 people show up for the flight)

p = P(will show for flight) = 1 - 0.04 = 0.96

n = 278

µ = n * p = 278 * 0.96 = 266.88

   σ = [tex]\sqrt{ n*p* (1 - p)} = \sqrt{278 * 0.96 * 0.04} = 3.2673[/tex]

Based on the percentage of games played at home by the team, and the percentage win rate, the probability that the team wins is 63.05%

First, find the probability that the team wins playing at home:

= Percentage win rate at home x Percentage played at home

= 83% x 65%

= 53.95%

Then find the probability of winning away:

= Percentage win rate away x Percentage played away

= 26% x (1 - 65%)

= 9.1%

The probability the team wins is:

= 53.95 + 9.1

= 63.05%

The cost for children meal is $16 and the.cost for adult meal is $26.

Let cost of adult meal = a

Let cost of child meal = c

Lexi plans to have 63 adults and 59 children attend, so the total projected cost of her meals is $2,582.This will be:

63a + 59c = 2582 ...... i

Raymond has 63 adults and 93 children on her guest list, so he will pay the caterer $3,126. This will be;

63a + 93c = 3126 ...... ii

Collect both equations

63a + 59c = 2582 ...... i

63a + 93c = 3126 ...... ii

Subtract i from ii

34c = 544

Divide

c = 544 / 34

c = 16

The cost of children meal is $16.

From equation i, 63a + 59c = 2582

63a + 59(16) = 2582

63a + 944 = 2582

Collect like terms

63a = 2582 - 944

63a = 1638

a = 1638/63

a = 26
