Answer:

Mean - 89

Median - 90.5

Mode - 89 or 92

Q1 - 84.5

Q3 - 96.5

IQR - 12

Step-by-step explanation:

A mean is an average. Just add all numbers then divide by how many numbers there are.

A median is a middle. Just arrange the numbers from smallest to largest and locate the middle value.

A mode is the number that appears most often. Count how many of each number there is.

Q1 is the middle of the lower half of the data.

Q3 is the middle of the upper half of the data.

IQR is the difference between Q3 and Q1. (subtract)

Write this equation in standard form y + 4 = 2/3 (x+7)

Karo-lina-s [1.5K]

Answer:

$y=\frac{2}{3}x+\frac{2}{3}$

Step-by-step explanation:

The standard equation of a straight line is of the form:

$y=mx+c$

We have to convert the given equation into above form.

Simplifying the given equation:

$y=\frac{2}{3}x+\frac{14}{3}-4$

$=\frac{2}{3}x+\frac{(14-12)}{3}$

$=\frac{2}{3}x+\frac{2}{3}$ .- This is in standard form

where $m=c=\frac{2}{3}$

Which equation(s) represents a proportional relationship? A) y = 5+x B) y = 4x C) y = 7x? D) y = 2-x

andreyandreev [35.5K]

Answer:

B & C

Step-by-step explanation:

A proportional relationship has a proportionality constant (constant rate of change) and and must cross through the origin (or begin at (0,0). This means it's y-intercept is 0. Each of the options is a linear function. All of the functions have a constant rate of change. Only one as b=0 or 0 as the y-intercept.

B) y=4x has a constant of 4 and passes through the origin.

C) y=7x has a constant of 7 and passes through the origin.

What is the value of x ???

k0ka [10]

Answer:

D. $2\sqrt {133}$

Step-by-step explanation:

${x}^{2} = {18}^{2} + ( {12}^{2} + {8}^{2} ) \\ \\ {x}^{2} = 324 + (144 + 64) \\ \\ {x}^{2} = 324 + 204 \\ \\ {x}^{2} = 528 \\ \\ x = \sqrt{532} \\ \\ x = \sqrt{4\times 133} \\ \\ x = 2\sqrt {133}$
