A person who is exercising should not exceed his or her maximum heart
rate, which is determined on the basis of that person's gender, age, and
resting heart rate. The table relates resting heart rate and maximum heart
rate for a 20-year-old man.
a) Use a graphing calculator to model the data with a linear function.
b) Estimate the maximum heart rate if the resting heart rate is 40, 60, 72,
and 80.
c) What is the correlation coefficient? How confident are you about using
the regression line to estimate function values?

Answers

Answer 1

Answer:5 star would be greatly aprreciated

For b) Estimating the maximum heart rate, a common formula used to calculate maximum heart rate is:

Max HR = 220 - Age

Since the person is 20 years old, the maximum heart rate can be estimated as:

Max HR = 220 - 20 = 200 beats per minute.

To estimate the maximum heart rate given a resting heart rate, we can use the formula:

Max HR = Resting HR + (Max HR - Resting HR) * Percentage of Max HR

Assuming a typical range of 70-85% of maximum heart rate during exercise, the estimated maximum heart rate for a resting heart rate of 40, 60, 72, and 80 beats per minute would be:

Resting HR = 40: Max HR = 140 + (200 - 140) * 0.85 = 170 beats per minute

Resting HR = 60: Max HR = 140 + (200 - 140) * 0.80 = 176 beats per minute

Resting HR = 72: Max HR = 140 + (200 - 140) * 0.75 = 182 beats per minute

Resting HR = 80: Max HR = 140 + (200 - 140) * 0.70 = 188 beats per minute

For c) the correlation coefficient, the coefficient measures the strength and direction of the linear relationship between two variables. A value close to 1 indicates a strong positive correlation, a value close to -1 indicates a strong negative correlation, and a value close to 0 indicates no correlation.

Answer 2
Final answer:

To model the data with a linear function, find the slope using two points from the table, and use the slope-intercept form of the equation to find the y-intercept. To estimate the maximum heart rate for different resting heart rates, substitute the values into the equation. The correlation coefficient cannot be determined based on the given table of data.

Explanation:

To model the data with a linear function, we can use the formula for the equation of a line, y = mx + b, where m is the slope and b is the y-intercept.

First, we need to find the slope (m). The slope is given by the formula: m = (y2 - y1) / (x2 - x1). We can choose any two points from the table to calculate the slope. Let's choose (60, 200) and (70, 180) as our two points.

Using the formula, we have m = (180 - 200) / (70 - 60) = -20 / 10 = -2.

Now, we can use the slope-intercept form of the equation to find the y-intercept (b). Let's substitute one of the points into the equation: 200 = -2(60) + b. Solving for b, we get b = 320.

Therefore, the equation of the linear function that models the data is y = -2x + 320.

To estimate the maximum heart rate for different resting heart rates, we can substitute the given values into the equation:

If the resting heart rate is 40: y = -2(40) + 320 = 240.

If the resting heart rate is 60: y = -2(60) + 320 = 200.

If the resting heart rate is 72: y = -2(72) + 320 = 176.

If the resting heart rate is 80: y = -2(80) + 320 = 160.

The correlation coefficient measures the strength and direction of the relationship between two variables. In this case, it represents the correlation between resting heart rate and maximum heart rate. The closer the correlation coefficient is to 1 or -1, the stronger the correlation. However, since we are given a table of data and not actual data points, we cannot calculate the correlation coefficient. We can only estimate it visually based on the scatter plot of the data points.

Therefore, the correlation coefficient cannot be determined and our confidence in using the regression line to estimate function values is limited.

What are the two equations for a cone's volume?

The volume of cone is calculated using the formula (1/3)r2h, where "h" stands for the cone's height and "r" for the base radius. As a result, (1/3)r2 is the cone's volume in terms of the slant height "L." (L2 - r2).

Volume of a cone:

Volume of a cone is given by the expression,

V = 1/3πr²h

Here,

r = radius of the cone

h = Height of the cone

Radius of the cone =  = 4 cm

Height of the cone = 11 cm

Amount of lemonade = 10 gallons

Volume of one cone = 1/3π(4)²× 11

 = 184.307 cm³

Covert the gallons into cubic cm,

  ∵ 1 gallon = 3785 cm³

  ∴ 10 gallons = 37850 cm³

  ∵1 cones are represented by a volume of 184.307 cm3.

∴ 1 cm³ will represent the volume = 1/184.307 cup

∴ 37850 cm³ will represent the volume = 37850/184.307 cups

                                                                  = 205.36 cups

                                                                   = 205 cups

Therefore, number of packs of cups to be bought = 205/50

                                                                                    = 5 packs

b). If 80% of the lemonade are sold, amount of lemonade sold = 10 × 80/100

= 8 gallons

Volume of 8 gallons lemonade in cm³ = 8 × 3785

                                                                    = 30280 cm³

Therefore, number of cups to be used = 30280/184.307 cups

= 164.29 cups

≈ 164 cups

Number of cups purchased = 250

And there are 250 cups left after subtracting 164.

                                                                = 86 cups

Therefore, number of cups remaining are 86 cups.

What is a Binomial Distribution?

The binomial distribution is a type of probability distribution that predicts the likelihood of obtaining one of two outcomes given a set of inputs. It summarizes the number of tries where each trial has the equal chance of producing the same result.

The formula for Binomial Distribution is given by

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

where

n = number of trials

x = number of successes

p = probability of getting a success in one trial

q = probability of getting a failure in one trial

q = 1 - p

Given data ,

Let the probability be represented as P

The total number of trials n = 5

The probability of getting a success p = 0.70

The probability of getting a failure q = 0.30

Now , the equation will be

a)

The probability that the player makes exactly 3 of the 5 shots = A

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 3

Substituting the values in the equation , we get

A = ⁵C₃ ( 0.70 )³ ( 0.30 )²

A = 10 ( 0.343 ) ( 0.09 )

A = 0.3087

So , probability that the player makes exactly 3 of the 5 shots is 0.3087

b)

The probability that the player makes exactly 4 of the 5 shots = B

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 4

Substituting the values in the equation , we get

B = ⁵C₄ ( 0.70 )⁴ ( 0.30 )¹

B = 5 ( 0.2401 ) ( 0.3 )

B = 0.36015

So , probability that the player makes exactly 4 of the 5 shots is 0.36015

c)

The probability that the player makes all 5 shots = C

P ( x ) = [ n! / ( n - x )! x! ] pˣqⁿ⁻ˣ  

n = 5

x = 5

Substituting the values in the equation , we get

C = ⁵C₅ ( 0.70 )⁵ ( 0.30 )⁰

C = 0.16807

So , probability that the player makes all 5 shots is 0.16807

d)

The probability that the player makes 3 or 4 of the shots = D

D = A + B

D = 0.3087 + 0.36015

D = 0.66885

Find the slope of the line between (19,-27) and (34,15)

Answers

Given the problem:
Find the slope of the line between (19,-27) and (34,15)

Whenever you’re given two points and asked to find a slope, simply remember this formula:
y2-y1/x2-x1
You basically take the y value of the second point and subtract that by the y value of the first point. Then divide that by the x value of the second point subtracted by the x value of the first point.
So let’s put in the numbers:
15- -27/34-19
Now solve! (Subtracting a negative makes it addition):
15+27/34-19
42/15
Simplify:
14/5
That’s your slope!
And remember the slope intercept form is y=mx+b
I see a lot of questions about slope intercept. And it looks like you’re somewhere around that unit. m is the slope, and b is the y intercept.
Hope this helped!

66 out of the 75 employees at the water slides are temporary employees what percentage of the employees at the water slides are temporary​

Answers

The percentage of the employees at the water slides are temporary​ is 88%

What is percentage?

A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred.

To find the percentage of the employees that are temporary

66/75 x 100/1

=88%

Hence, 88% is the percentage of the employees at the water slides are temporary​

What are similar triangles?

Similar triangles share these two features listed as follows:

Congruent angles, that is, angles that have the same measure.Proportional side lengths.

The similar triangles for this problem are given as follows:

AOB and COD.

Hence the proportional relationship established between the side lengths is given as follows:

OA/OC = OB/OD = 1/4 = AB/DC.

Taking the last two terms, considering that AB = 20 cm, the length of DC is given as follows:

DC = 4 x AB

DC = 4 x 20 cm

DC = 80 cm.

Hence the statement is false, as the length is of 80 cm and not of 120 cm.

what is function?

The subject of mathematics includes quantities and their variations, equations and related structures, shapes and their locations, and places where they can be found. The term "function" refers to the relationship between a set of inputs, each of which has an associated output. A connection between inputs and outputs in which each input leads to a single, distinct result is known as a function. Each function is given a domain and a codomain, or scope. Usually, f is used to denote functions (x). input is an x. There are four main types of functions accessible. based on the following factors: on functions, one-to-one functions, many-to-one functions, inside functions, and on functions.

the increasing order of the function is

y = 5/2x +10 < y = 3/2x+1/2 < y = 1/2x - 2 < y = 3/4x - 7/3 < y = -1/2x + 1/2 < y = 3/2x - 11/2

The solution of the matrix product is:

[tex]\left[\begin{array}{ccc}4&0\\-16&-7\\\end{array}\right][/tex]

How to find the product?

Remember that the general product between two 2by2 matrices can be written as:

[tex]\left[\begin{array}{ccc}a_{11}&a_{12}\\a_{21}&a_{22}\\\end{array}\right] *\left[\begin{array}{ccc}b_{11}&b_{12}\\b_{21}&b_{22}\\\end{array}\right] = \left[\begin{array}{ccc}a_{11}*b_{11} + a_{12}*b_{21}&a_{11}*b_{12} + a_{12}*b_{22}\\...&...\\\end{array}\right][/tex]

So we multiply the the rows of the first matrix by the columns of the second one, then our product will be:

[tex]\left[\begin{array}{ccc}1&2\\-4&3\\\end{array}\right] *\left[\begin{array}{ccc}4&1\\0&-1\\\end{array}\right] = \left[\begin{array}{ccc}1*4 + 2*0&1*1 + 2*-1\\-4*4 + 3*0&-4*1 + 3*-1\\\end{array}\right]\\\\= \left[\begin{array}{ccc}4&0\\-16&-7\\\end{array}\right][/tex]

That is the solution of the product.
