The median is the one in the middle. Sorting the data gives

$1.61, $1.75, $1.79, $1.84, $1.96, $2.09, $2.11

Seven data points and the fourth one is 1.84.

What is one of the solutions to the following system of equations? y2 + x2 = 53 and y − x = 5

Aneli [31]

Y2 + x2 = 53
y − x = 5
y = 5 + x

(5+x)^2 + x^2 = 53
(5+x)(5+x) + x^2 = 53
25 + 10x + x^2 +x^2 = 53
2x^2 + 10x - 28 = 0
(x-2)(x+7)=0
x = 2 , x = - 7

y = 5 + 2
y = 7

y = 5 +(-7)
y = 5 - 7
y = - 2

In the given diagram, if AP = 15 cm, AQ = 24 cm and PB + QC = 26 cm, find QC – PB, given PQ || BC.

Anna35 [415]

Answer:

QC - PB = 6

Step-by-step explanation:

Given PQ is parallel to BC then it divides the sides proportionally, that is

$\frac{AP}{AQ}$ = $\frac{PB}{QC}$ = $\frac{15}{24}$ = $\frac{5}{8}$ , then

$\frac{PB}{QC}$ = $\frac{5}{8}$ ( cross- multiply )

8PB = 5QC → *

Given PB + QC = 26 , then

PB = 26 - QC

Substitute into *

8(26 - QC) = 5QC ← distribute left side

208 - 8QC = 5QC ( subtract 5QC from both sides )

208 - 13QC = 0 ( subtract 208 from both sides )

- 13QC = - 208 ( divide both sides by - 13 )

QC = 16

Thus PB = 26 - QC = 26 - 16 = 10

QC - PB = 16 - 10 = 6
