A group of friends wants to go to the amusement park. They have $69. 75 to spend on parking and admission. Parking is $17. 25, and tickets cost $17. 50 per person, including tax. Write and solve an equation which can be used to determine pp, the number of people who can go to the amusement park.

Answers

Answer 1

The equation to determine the number of persons is x/(y+z) and total 2 people are there in total.

What does a math equation mean?The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions.For instance, the equation 3x + 5 = 14 consists of the two expressions 3x + 5 and 14, which are separated by the 'equal' sign.

Given: Several buddies want to visit the theme park. Spending money for parking and entry totals $69.75. Tickets cost $17.50 per person, tax included, and parking is $17.25.

Let,

x = total amount for parking and admission fee

y = ticket per person

z = parking cost per person

Total number of people who can go to the amusement park is given as:

= x/(y+z)                                                                                               =69.75/(17.50+17.25)

= 2

Therefore, the equation to determine the number of persons is x/(y+z)   and total 2 people are there in total.

flipping a fair two-sided coin, the probability of getting heads is equal to the probability of getting tails. if the coin is flipped three times consecutively, what is the probability of getting heads at least twice?

Answers

The probability of getting heads at least twice is 0.5

Since we are given two-sided coin, where the probability of getting heads is equal to the probability of getting tails.NO of outcomes in this case is 2,The probability of getting a head = 1/2, similarly probability of getting a  tail is =1/2 .So when a coin is flipped three times, the sample space for the event will be (HHH, HHT, HTH, HTT, THH, THT, TTH, TTT),  H stands for head and T stands for tails, here for tossing the coin the number of outcomes is 8  .So the probability of getting at least two heads is:  4/8= 1/2 =0.5

a researcher wants to examine the relationship between fat and calories in fast food. data was analyzed using linear regression. fat grams in the food represented x (the independent variable) and total calories in the food item was represented by y. the slope was 13 and the y intercept was 143. predict how many calories would be in a sandwich containing 32 grams of fat?

Answers

The predicted number of calories in a sandwich containing 32 grams of fat is 559.

What is the slope intercept form?

In algebra, the slope-intercept form of a linear equation is a typical approach to express a line on a graph. A linear equation is written as y = mx + b in standard form.

The y-intercept, or place where the line crosses the y-axis, is represented by the letters b and m, respectively. The point where the lines contacts the y-axis is known as the y-intercept, and the slope is a measurement of how steep the line is. Because it explicitly displays the slope and y-intercept, this equation's form is known as the slope-intercept form.

y = mx + b

Where m is the slope, x is the value of the independent variable, and b is the y-intercept. In this case, the slope is 13 and the y-intercept is 143. So, the equation of the line of best fit is:

y = 13x + 143

To predict the number of calories in a sandwich containing 32 grams of fat, you can plug in 32 for x in the equation:

y = 13 * 32 + 143

y = 416 + 143

Number of positive real roots of f(x) ≤ Number of sign changes f(x)

Number of negative roots of f(x) ≤ Number of sign changes of f(-x)

According to the given questions:

The given polynomial function f(x) = x³ - x² - x - 5

We can observe the number of sign changes in the coefficients

The sign changes only once

hence there is one positive real root

A persons resting heart rate is typically between 60 and 100 beats per minute. Rushing looks at the watch and counts 8 heartbeats in 10 seconds. Is his heart rate typical?

Answers

Answer: No its not normal

Step-by-step explanation: The question says 60 and 100 beats per minute is normal. Rushing looks at his watch and counts 8 beats in 10 seconds

We can solve by:

[tex]\frac{8}{10}[/tex] = [tex]\frac{x}{60}[/tex] then from that answer we can check if x, the heartbeats falls between 60 and 100.

So to get 60, we have to multiply 10 by 6. We are using proportionality, so we do the same to the numerator to get 8 x 6= 48

We get  [tex]\frac{8}{10}[/tex] = [tex]\frac{48}{60}[/tex]. 48 beats do not fall between 60 and 100, thus the answer is it is not normal.

a rancher has 720 feet of fencing with which to enclose two adjacent rectangular corrals (see figure). what dimensions should be used so that the enclosed area will be a maximum?

Answers

If a rancher has 720 feet of fencing with which to enclose two adjacent rectangular corrals, the dimensions are 90 feet and 120 feet

From the figure

4x + 3y = 720

3y = 720 - 4x

y = 240 - (4/3)x

The area = l × w

Where l is the length

w is the width

Substitute the values in the equation

A = 2x × y

= 2x (240 - (4/3)x)

Apply the distributive property

= 480x - (8/3)x^2

Differentiate the values

0 = (-16/3)x + 480

(16/3) x = 480

x = 480 / (16/3)

x = 90 feet

Then,

y = 240 - (4/3)(90)

= 120 feet

Hence, the dimensions are 90 feet and 120 feet

Here, we

Let the east direction is denoted by x and

the north direction is denoted by y.

dx / dt = 16 miles per hour

dy / dt = 12 miles per hour

x = 4 miles

Let the distance between both the friends be s.

Time is taken by you to travel 4 miles,

time = distance / speed = 4 / 12 = 1/4 hour

Distance traveled by your friend in time t,

y = speed x time = 12 x 1/4 = 3 miles

By Using the Pythagorean theorem,

x² + y²  = s²     ..... (1)

Substitute, x = 4 mile, y = 3 mile

s²  = 16 + 9 = 25

s = 5 miles

Now, Differentiate equation (1) with respect to t, we get

Answers

In the given question, the absolute percentage increase is 1050 and the relative percentage increase is 32.3076%.

What is the percentage increase?

When you want to analyze how a value has evolved over time, a percentage increase is helpful.

Although percentage increase and absolute increase are fairly comparable, the former is more helpful when contrasting different data sets.

For instance, a change from 1 to 51 and a change from 50 to 100 both have an absolute change of 50, but the first change grew significantly more due to the higher percentage growth of 5000% compared to the second change of 100%.

The most popular method of assessing growth is percentage increase because of this.

So, the absolute and relative percentage increase is:

The town's population grew from 3,250 in 2008 to 4,300 in 2010.

2008: P1 = 3250

2010: P2 = 4330

Absolute variation:

Absolute difference = P2 - P1

Absolute difference = 4330 - 3250

Absolute difference = 1050

Relative increase:

Relative percentage = P2 - P1/P1 * 100

Relative percentage = 1050/3250 * 100

Relative percentage = 32.3076

Therefore, in the given question, the absolute percentage increase is 1050 and the relative percentage increase is 32.3076%.

The array's first two members are initially compared using an insertion sort.

Since 9 is bigger than 2, they are not arranged in ascending order, and 2 is not in the proper place. So, switch 9 and 2.

Therefore, 2 is currently kept in a sorted sub-array.

A test statistic is a figure obtained from a statistical analysis. It explains how far your observed data is from the null hypothesis, which states that there is no correlation between the variables or distinction between the sample groups.

Given,

            [tex]H_0:\sigma =0.1\\H_a:\sigma \neq 0.1[/tex]

Test statistic:

Chi square=(20-1)*0.25^2/0.1^2=118.75

df=20-1=19

p-value=CHIDIST(118.75,19)=0.0000

Reject the null hypothesis.

Hence, there is sufficient evidence to conclude that the population standard deviation is different from 0.1.
