Answers

Answer:

the price of each snack be R $9.00

Step-by-step explanation:

Let us assume the snack be x

And, the ice cream be y

Now according to the question

2x + y = $21

And,

3x  + 2y = $33

Now multiply by 2 in equation 1

So,

4x + 2y = $42

3x + 2y = $33

x = 9

Hence, the price of each snack be R $9.00

Answer:

243 m²

Step-by-step explanation:

Given the scale is 4 : 6 = 2 : 3 , then

scale of areas = 2² : 3² = 4 : 9

area of scale drawing = 12 × 9 = 108 cm²

let x be the actual area then using proportion

[tex]\frac{4}{108}[/tex] = [tex]\frac{9}{x}[/tex] ( cross- multiply )

4x = 972 ( divide both sides by 4 )

x = 243

Actual area = 243 m²

The box and whisker plots represent the number of minutes spent by users on two different social media groups. Which THREE statements are correct when comparing the plots?

B) Group B has greater median value than Group A.

C) The data for Group B varies slightly more than Group A.

D) The spread of the data for Group A is 25 minutes.

E) The spread of the data for Group A is 40 minutes. ​

Answers

Answer: I feel the answer is C

Step-by-step explanation:

The three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.

What is a box and Whisker plot?

A box and whisker plot displays the minimum value, lower quartile (Q1), median, upper quartile (Q3), and maximum values of a data set.

Let's analyze each of the given statements given the box and whisker plots for both groups:

Statement A is TRUE:

Median time for Group B = 40.

Statement B is FALSE:

Median value for Group A is between 45 and 50

Median value for Group A is 40.

Therefore, Group B does NOT have median value greater than Group A.

Statement C is TRUE:

The interquartile range (IQR) for Group A and Group are similar, therefore, data for Group B varies slightly more than Group A.

Statement D is TRUE while E is FALSE:

Spread for Group A (IQR) = 55 - 30 = 25 minutes

Therefore, the three statements that are correct when comparing the box and whisker plots for the two groups are: A, C, and D.

Solve the equation. x6−9=7 x = ___ (type only an integer - no words, variables, or equal signs)

Answers

Answer:

We want to solve the equation:

x*6 - 9 = 7

To solve this we need to isolate x in one side of the equation.

First, we need to add 9 in both sides of the equation to get:

(x*6 - 9) + 9 = 7 + 9

x*6 - 9 + 9 = 16

x*6 = 16

Now we can divide both sides by 6, to get:

x*6/6 = 16/6

x = 16/6 = 2.66

This is not an integer as the question wants, so i only can suppose that the question is incorrectly written.

If the equation was something like:

x/6 - 9 = 7

Using the same approach than before (the only difference is that we multiply both sides by 6 in the second step), we would get:

x/6 = 7 + 9 = 16

x/6 = 16

x = 16*6 = 96

x = 96

Which is an integer, so i suppose that the actual equation is "x/6 - 9 = 7" instead of "x*6 - 9 = 7"

Josie wants to build a slide that is 15 feet long. If the angle of elevation for the side will be 30 degree, how high in feet will the top of the slide be ?

Answers

Answer: 7.5

Step-by-step explanation: draw a right triangle to represent the slide. the slide is 15 feet long, so the hypotenuse of the right triangle would be 15 feet. The angle from the bottom is 30 degrees according to the question. You want to find the angle opposite from the 30 degree angle so use sin(30). Sin=opposite/hypotenuse so sin(30)=x/15 sin(30) is 1/2 so 1/2=x/15. You multiply by 15 on both sides to get x by itself. 1/2*15=7.5

The scatter plot shows the amount of sleep Aria got the night before a test and her test scores. Use the y-intercept, (0, 62), and the point (6, 80) from the line on the scatter plot. What is the equation of the trend line? (*Note: Enter your response as an equation in y=mx+b form. Enter no spaces & use only lower-case letters. Ex: y=10x+5 ) *

Answers

Answer:

y = 3x + 62

Step-by-step explanation:

Trend line equation in the form :

y = mx + b

m = slope

b = intercept

Using the points :

(0, 62) ; (6, 80)

Slope, m = Rise / Run = (y2-y1) / (x2 - x1)

y2 = 80 ; y1= 62 ; x2 = 6 ; x1 = 0

m = (80 - 62) / (6 - 0)

m = 18 / 6

m = 3

Intercept, b = value of y when x = 0

(0, 62) ; hence, b = 62

y = 3x + b

y = 3x + 62


Jana, a high school principal, hosted a movie event at her school. Jana's assistant kept track of the number of students in each grade who attended the event. The distribution shown in the table
represents the number of students in each grade that were present.
Grade Level
Sophomore-56
Senior-70
Freshman-52
Junior-60
Jana knows that the grade levels are equally distributed across the school of 1,200 students. She would like to use a chi-square test to see if the proportion of individuals in each class at the
movie are also equally distributed. How many seniors would be expected at the event?

Answers

Answer:

59.5 Seniors expected

Step-by-step explanation:

"Equally distributed" means that it is expected that each grade has equal number of students for 1200 schools. This means 1200/4 = 300 students expected in each grade for 1200 students. The proportion would be 300/1200 = .25

The actual total of the school shown is (56+70+52+60) = 238

Therefore 238 * .25 = 59.5 expected students in each grade for this school

The proportion for each grade can also be found by just knowing that each grade has the same proportion.There are 4 grades so 1/4 = .25
