$\sf \red{1. \: (3x - x) (x + 2) = 0}$

$\sf \red{2. \: (q + 2)^{2} - 40}$

$\large{\underline{\underline{\pmb{\frak {\color {blue}{Answer:}}}}}}$

2.soln:

(q + 2)² - 40

=> (q)² + 2.q.2 + (2)² - 40

=> q² + 4q + 4 - 40

=>q² + 4q - 36

Here, a = 1, b = 4 and c = - 36

By, using Quadratic formula

Given:

The data set is

21, 16, 30, 15, 16, 18, 10, 24, 26, 20, 19, 24, 24, 25, 23

10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30

To find:

The range, average and median for the given data set.

Solution:

Arrange the data set in ascending order.

10, 15, 16, 16, 18, 19, 20, 21, 23, 24, 24, 24, 25, 26, 30

(1)

Range = Maximum value - Minimum value

= 30 - 10

= 20

Therefore, the range of the given data set is 20. All the options are incorrect.

(2)

$Average=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}$

$Average=\dfrac{311}{15}$

$Average\approx 20.73$

Therefore, the average score is about 20.73. All the options are incorrect.

(3)

Number of observations = 15, which is odd.

$Median=\dfrac{n+1}{2}\text{th term}$

$Median=\dfrac{15+1}{2}\text{th term}$

$Median=\dfrac{16}{2}\text{th term}$

$Median=8\text{th term}$

In the arranged data set 8th term is 21.

$Median=21$

Therefore, the correct option is b.

Help! I will mark you the brainest !! ☺️☺️

Marizza181 [45]

Answer:

Part 1) $0.675\%$

Part 2) $475\%$

Part 3) $8\%$

Part 4) $\frac{67}{20}$

Part 5) $2.65$

Step-by-step explanation:

Part 1) Write as a percent 0.00675

we know that

To write a number as a percent, multiply the number by 100

so

$0.00675*100=0.675\%$

Part 2) Write as a percent 4 3/4

Convert mixed number to an improper fraction

$4\frac{3}{4}=\frac{4*4+3}{4}=\frac{19}{4}$

we know that

To write a fraction as a percent, multiply the fraction by 100

$\frac{19}{4}*100=19*25=475\%$

Part 3) Write as a percent 2/25

we know that

To write a fraction as a percent, multiply the fraction by 100

$\frac{2}{25}*100=2*4=8\%$

Part 4) write as a fraction 335%

we know that

$335\%=\frac{335}{100}$

Simplify

Divide by 5 both numerator and denominator

$\frac{335}{100}=\frac{67}{20}$

Part 5) Write as a decimal 265%

we know that

$265\%=\frac{265}{100}=2.65$

What is the solution to the inequality below?

anastassius [24]

B because a negative squared is always a positive and it has to be a negativ number less than -3 is less than 9 and if it is greater than 3 than it would make it untrue.

Find the equation of the line that passes through the points (12,21) and (46,33). V.35r-162

AnnZ [28]

Answer:

the answer is Y=(6/17)X + (285/17)

Step-by-step explanation:

1. Identify the X and Y coordinate of each point.

for example, the first point could be (12,21), therefore X1 = 12 and Y1 = 21 and the second point is then (46,33), therefore X2 = 46 and Y2 = 33

2. to find the equation of the line it is necessary to find the slope.

knowing that the equiation of the slope is M = Y2-Y1/X2-X1 we replace

$m=\frac{33-21}{46-12}=\frac{12}{34}$ and then we simplify the result to $\frac{12}{34}$

3. Using the Point-slope equation which is Y-Y1=M(X-X1) we replace

$Y-33=\frac{6}{17}(X-46)$

$Y=\frac{6}{17}X-\frac{276}{17}+33$

$Y=\frac{6}{17}X+\frac{285}{17}$
