Q. Find the range and coefficient of range of the data :

⇾ Solution :

largest value ( L ) = 900 & smallest value ( S ) = 100

We know , Range is the difference between the largest and smallest value. By definition ,

1. Range = Largest value - Lowest value = 900 - 100 = [tex] \boxed{ \sf{800}}[/tex]

When x = 4 , f ( 4 ) = 9 × 4 - 8× 4 = 4

When x = 3 , f ( 3 ) = 9 × 3 - 8 × 3 = 3

When x = 5 , f ( 5 ) = 9 × 5 - 8 × 5 = 5

Range = { 0 , 4 , 3 , 5 )

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

Hii! I need help with this question! The question is "You have 8 hours to get ready and 5 1/2 of those hours have already passed. How much time do you have left?" Someone help ASAP!

Answers

Answer:

2 1/2 hours

Step-by-step explanation:

Answer:

3 1/2 hours left

Step-by-step explanation:

Write an equation for this:

8 - 5 1/2 = how much time you have left

(8 is the total hours, you subtract since the hours passed, and 5 1/2 is the amount of hours passed)

Solve equation:

8 - 5 = 3, add the 1/2

So, 8 - 5 1/2 = 3 1/2 or 3.5

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"

Konni and her son, Declan, went for a run. Declan ran for a total of 27 minutes and 45 seconds. Konni ran for twice as long as Declan. How much time did Konni spend running?

Answers

Answer:

Konni spent 55 minutes and 30 seconds running.

Step-by-step explanation:

27 x 2 = 54

30 x 45 = 90

90/60 = 1.5

1.5 minutes is one minute and 30 seconds.

55 minutes and 30 seconds

Just double it. 27 * 2 = 54 minutes, 45 * 2 = 90 seconds, or 1 minute and 30 seconds, so 55 minutes and 30 seconds

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

Answers

9514 1404 393

Answer:

  25,975 in²

Step-by-step explanation:

Since your j+k < i, we assume that not all of these dimensions are side lengths. If we assume ...

  i = 170 in

  J = 119°

  K = 42°

Then we can find side j using the law of sines.

  I = 180° -119° -42° = 19°

Then the law of sines tells us ...

  j/sin(J) = i/sin(I)

  j = i·sin(J)/sin(I) = (170 in)sin(119°)/sin(19°) = 456.695

Then the area of the triangle is ...

  A = (1/2)(i·j·sin(K)) = (1/2)(170 in)(456.695 in)sin(42°) ≈ 25,975.03 in²

The area of triangle IJK is about 25,975 square inches.

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.
