I have attached a picture of the question.​

Hi there!

We have the numbers:

79  85  98  125  140

From the data, we can see that '98' is the median value as it is exactly in the middle. We can then split the data into equal groups on both sides of the median.

79  85

125  140

Since there are only two numbers, we can find the median of EACH sub-group (Q1 and Q3 respectively) by taking the average.

Q1 = (79 + 85)/2 = 82

Q3 = (140 + 125)/2 = 132.5

The IQR is simply the difference between Q3 and Q1, so:

IQR = 132.5 - 82 = 50.5

is your correct answer

Step-by-step explanation:

there are 50 students and 5 prizes (1 + 1 + 3).

so, already in natural language we would say "there is 1 prize for every 10 students".

formally, remember the rule of probability : desired outcomes over total possible outcomes.

this is here

5/50 = 1/10 = 0.1

your can see it also this way :

if there was only 1 prize, each student would have a chance of 1/50 of winning.

now there are 5 prizes, which gives everybody 5 times the chance of winning. which is then 5×1/50 = 5/50 = 0.1

General form of a quadratic equation: [tex]ax^2+bx+c[/tex]

  ⇒ since the equation: [tex]-x^2-2x+8[/tex]

     ⇒ so:

To calculate the x-coordinate of the vertex

  ⇒use x = [tex]-\frac{b}{2a}[/tex]   <--- this is a property that helps you find the vertex of the

                                 quadratic

      x = [tex]-\frac{(-2)}{2*(-1)} =-1[/tex]

Since x = -1:

    ⇒ we can plug in this x-value into the original equation to find the y-

         value

          [tex]y =-(-1)^2-2(-1)+8=-1+2+8=9[/tex]

So the coordinate of the vertex: (-1,9)

Answer: [tex]f(x)=2x^2+5[/tex]

Step-by-step explanation:

First integrate f'(x) so we can find the funtion f(x):

[tex]4\int\limits {x} \, dx =4[\frac{1}{2} x^2]=2x^2+C=f(x)[/tex]

The initial conditions say that when x = 0, the function equals 5. Let's write that down:

[tex]f(0)=5=2(0^2)+C=C[/tex]

Therefore, the integration constant 'C' must equal 5. This means that our function is:

[tex]f(x)=2x^2+5[/tex]

Answer:

Step-by-step explanation:

If you multiply top and bottom of 7/2 by 2 as in (7 *2) / (2 * 2) = 14 /4

If you multiply 7/2 top and bottom by 4, you get 28/8

So 14/4 and 28/8 are both the same as 7/2

Answer:

0.000299 in scientific notation

2.99 × 10-4

Step-by-step explanation:

To convert 0.000299 into scientific notation also known as standard form, follow these steps:

Move the decimal 4 times to right in the number so that the resulting number, m = 2.99, is greater than or equal to 1 but less than 10

Since we moved the decimal to the right the exponent n is negative

n = -4

Write in the scientific notation form, m × 10n

= 2.99 × 10-4

Answer:

0.000299

2.99 × 10^-4.

making proportional equations

Answer:

12x + 16y = 3700

x + y = 250

x = 75 students

y = 175 adults

Step-by-step explanation:

y = 250 - x

12x + 16(250-x) = 3700

12x + 4000 - 16x = 3700

-4x = -300

x = 75

y = 250 - 75

y = 175

Answer:

A) 29/8

Step-by-step explanation:

Identify the blocks. As you can see there are 5 x blocks on the left, and 9 -1 blocks on the left. On the right there are 3 -x blocks and 20 1 blocks. With this, form the equation.

5x - 9 = -3x + 20

Add 3x to both sides.

8x - 9 = 20

Add 9 to both sides.

8x = 29

Divide both sides by 28 to get:

x = 29/8.

Answer:

-30

Step-by-step explanation:

Using 'y' is vary inversely to 'x', the value of x₂ = -27.

The word inverse in mathematics "a function or operation which reverses the order or operation of another function or operation".

According to the question,

x₁ = 36,  y₁ = -6, y₂ = 8 and x₁ is inversely proportional to y₁ which mean

(x₁) (y₁) = k

(36)(-6)  = -216.

Formula for inverse is x = k([tex]\frac{1}{y}[/tex]).

In order to find x₂, x₂ = -216(1/8)

x₂ = -27

Hence, the value of x₂ = -27.
