Answer:

For the d day Jackson exercised for t(d)=  30 + 2d where d is the number of day.

t(d)= 30 + 2d

Step-by-step explanation:

Let the total time on the treadmill be given by y each day and let x take the values of number of the days exercised . For the first day x= 0  and so on.

Therefore

For the first day Jackson exercised for  30 minutes

y= 30 + 2x

y= 30 + 2(0)

y= 30 minutes

For the second day Jackson exercised for (x=1) 32 minutes

y= 30 + 2x

y= 30 + 2(1)

y= 32 minutes

For the third day Jackson exercised for (x=2) 34 minutes

y= 30 + 2x

y= 30 + 2(2)

y= 34 minutes

For the fourth day Jackson exercised for (x=3) 36 minutes

y= 30 + 2x

y= 30 + 2(3)

y= 36 minutes

For the d day Jackson exercised for (x=d) 30 + 2d where d is the number of day.

y= 30 + 2x

y= 30 + 2(d)

y= 30 + 2d

Answer:

Step-by-step explanation:

The antenna height is 41.23 feet if the support wire is attached to the top of the antenna.

Trigonometry is a branch of mathematics that deals with the relationship between sides and angles of a right-angle triangle.

We have:

A support wire is attached to the top of an antenna. The support wire connects to the ground 15 feet from the bottom of the antenna.

Let x be the height of the antenna.

We can find the length of the antenna using the trigonometric ratios:

As we know, the trigonometric ratio is defined as the ratio of the pair of a right-angled triangle.

Applying tan ratio in the right angle triangle:

tan70 = x/15

x =15tan70

x = 41.212 feet  ≈ 41.23 feet

Thus, the height of the antenna is 41.23 feet if the support wire is attached to the top of the antenna.

Answer: [tex]6x-5[/tex]

Step-by-step explanation:

Given

The side lengths of a triangle are  [tex]3x-5, 2x-1,\text{and}\ x+1[/tex]

Perimeter(P) is the sum of the side length of the triangle i.e.

[tex]\Rightarrow P=3x-5+2x-1+x+1\\\Rightarrow P=6x-5[/tex]

Therefore, the perimeter of the triangle is [tex]6x-5[/tex]

Answer:

z = -2.13

Therefore, the standardized z score for the state of Colorado means the score is below the mean.

Step-by-step explanation:

The formula for z score is given as:

z = (x-μ)/σ,

where

x is the raw score = 9.7%

μ is the population mean = 13.26%

σ is the population standard deviation = 1.67%

z = z score or standardize score

Hence,

z = 9.7 - 13.26/1.67

z = -2.13174

Approximately z = -2.13

Therefore, the standardized z score for the state of Colorado means the score is below the mean

Answer:

The given statement is true

Step-by-step explanation:

Complete question

As a result of aerobic respiration, the composition of the air that is breathed in and the air that is breathed out changes. Is this true

Solution

Yes the composition of gases inhaled and exhaled are of different composition.

We intake oxygen from atmosphere while breathing in. However, while breathing out we release carbon dioxide (CO2).

Hence the given statement is true.

Step-by-step explanation:

Based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).

Random sample is the way to choose a number or sample in such a manner that each of the sample of the group has an equal probability to be chosen.

When the sample size is less than 30, the formula which is used is,

[tex]\overline x\pm t.\dfrac{s}{\sqrt n}[/tex]

Here, n is the sample size, [tex]\overline x[/tex] is the sample mean, s is the standard deviation.

Economist, takes an SRS of 12 gas stations. The sample size for the given problem is 12,

[tex]n=12[/tex]

Thus, degree of freedom,

[tex]df=12-1\\df=11[/tex]

In the t table, for df 11, the value of t is 1.796.

An economist studying fuel costs wants to estimate the mean price of gasoline in her state on a certain day.

On that day, she takes an SRS of 12 gas stations and finds the sample mean price (in dollars per gallon) is,

[tex]\bar x=2.29[/tex]

With a standard deviation of

[tex]s_x=0.20[/tex]

Put the values in the above formula,

[tex]2.29\pm 1.796.\dfrac{0.20}{\sqrt 12}\\2.29\pm 0.1037\\2.29+0.1037=2.3937\\2.29- 0.1037=2.1863[/tex]

Thus, based on this sample, the confidence interval which is closest to a 90%, for the mean price of gasoline that day in her state is ($2.19, $2.39).

Answer:

B. Stratified random sample is the correct answer

The best sampling method that describes the scenario where students from each grade (6th, 7th, and 8th) are randomly chosen in a sample of 15 students from each grade is B) stratified random sample.

In a stratified random sample, the population is divided into distinct groups or strata based on certain characteristics, and then a random sample is taken from each stratum. In this case, the distinct groups are the different grade levels (6th, 7th, and 8th grades). By randomly selecting 15 students from each grade, we ensure representation from each grade level in the sample.

This method allows for a more accurate representation of each grade level within the sample and can provide valuable insights into the characteristics and experiences of students in each grade.
