A survey asked 100 adults about car ownership and ride-sharing apps. Of the 38 people without a car, 29 have ride-sharing app on their phone. A total of 47 people have a ride-sharing app on their phone.

What percentage of people surveyed who own a car have a ride-sharing app on their phone? Round to the nearest whole percent.
Enter the correct answer in the box.

Answer:

Solution:- In the given figure

Side of square= 10 cm

area of square =  side x side m= 10 x 10 = 100 sq cm

Now , diameter of semi circle AOD = 2r = 10cm

⇒ radius of  semi circle AOD = 5 cm

∴ area of AOD =  

similarly Area of semicircle BOC =  

Area of white portion in figure 1 = area of square - [ area of semicircle BOD + area of semicircle AOD]

=

Total area of white portion in the given figure=

∴Area of Shaded portion = area of square - area of total white portion

=  

So the area of shaded portion is  

Now perimeter of AD(which is a semicircle) = (as perimeter of semicircle=πr)

So the perimeter of shaded region = 4×perimeter of AD=4×15.7=62.8cm

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.

Step-by-step explanation:

You need to divide 600 by .35

Answer is

Answer:

[tex](a)[/tex]

[tex]Pattern: 2187, 729, 243, 81, 27, 9,3, 1[/tex]

[tex](b)[/tex]

[tex]Pattern = 972,324,108,36[/tex]

Step-by-step explanation:

Given [Missing from the question]

[tex]Pattern: 2187, 729, 243, 81[/tex]

Solving (a): Continue the pattern using the divide by 3 rule

To do this, we simply divide the last term by 3, to get the next term.

So, we have:

[tex]81/3 = 27[/tex]

[tex]27/3 = 9[/tex]

[tex]9/3 = 3[/tex]

[tex]3/3 = 1[/tex]

So, the pattern is:

[tex]Pattern: 2187, 729, 243, 81, 27, 9,3, 1[/tex]

Solving (b): 4 terms of a different pattern using the same rule.

Let the first term be: 972

So, the next three terms is:

[tex]972/3 =324[/tex]

[tex]324/3 = 108[/tex]

[tex]108/3 =36[/tex]

So, the pattern is:

[tex]Pattern = 972,324,108,36[/tex]

Answer:

The answer is 9.625

Step-by-step explanation:

So what you have is the area and the base of the rectangle. To find the height, just divide 4 into 38.5

38.5 / 4 = 9.625

To double check just multiple 9.625 by 4

9.625 x 4 = 38.5

Answer:

The answer is 8 below is how you do it.

Step-by-step explanation:

first combine like terms 3x-8x

then you will have 5x

then do 40/5 and you will get x=8

Ok so to solve for x you need to isolate the variable. Usually, when solving an equation the first step would be to get all of the variables of x on the same side but this equation is already set up that way. Since 3x and 8x are both of the variable x you can simply subtract them and you would be left with:

-5x=-40

Now what you want to do is completely isolate x to get it by itself in which you would divide both sides by -5. Remember *When solving an equation you must do the same math to both sides.

-5x/-5=-40/-5

x=8

So the answer would then be 8. Also remember you can always check to see if your equation is correct by plugging your answer into the original equation

3(8) - 8(8) = -40

24 - 64 = -40

-40 = -40

Hope this helped :)

The length of the side would be sqrt(77) = 8.7749.....

Answer:

=225

Step-by-step explanation:

The value of x² - 2xy + y² would be; 225

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

we are given that (x-y)=15

The identity (x + y)² - (x - y)² = 4xy.

(x + y)²= (x² + 2xy + y²)

we have been asked to find x² - 2xy + y²

x² - 2xy + y² = (x - y)²

x² - 2xy + y² = 15²

x² - 2xy + y² = 225

The standard error of the sampling distribution is 0.014. The closest option to 0.014 among the answer choices is C. 0.045, but it is not a match. None of the provided answer choices matches the calculated value exactly.

To find the standard error of the sampling distribution, we can use the formula:

[tex]Standard Error = \sqrt{[(sample proportion * (1 - sample proportion)) / sample size]}[/tex]

Given a sample size of 120 and a sample proportion of 0.4, we can calculate the standard error as follows:

[tex]Standard Error = \sqrt{[(0.4 * (1 - 0.4)) / 120]}\\Standard Error = \sqrt{[(0.4 * 0.6) / 120]}\\Standard Error = \sqrt{[0.024 / 120]}\\Standard Error = \sqrt{0.0002}\\Standard Error \approx 0.014[/tex]

Rounded to three decimal places, the standard error is approximately 0.014.

Step-by-step explanation:

Step-by-step explanation:

For 3 scoops = 18 cookies

Lets use the unitary method,

So for 1 scoop, how many cookies?

So, 18 /3 = 6

So, 1 scoop = 6 cookies

So for 4 scoops we will multiply by 6 (as 1 scoop = 6 cookies)

So, 4 x 6 = 24

So, 24 cookies can be made if we add 4 scoops of flour

4 scoops = 24 cookies
