The area of a parallelogram is given by the formula A=bh the area of the parallelogram on the right is 126 sq units. Find its ba
Elden [556K]
From the diagram we have

Base = 4x+1
Height = x+1

Area = Base × Height
126 = (4x+1)(x+1) ⇒ Expand the double bracket
126 = 4x^{2}+5x+1 ⇒ Subtract 126 both sides
0 = 4x^{2}+5x-125 ⇒ Factorise the quadratic expression
0 = (x-5)(4x+25) ⇒ Equating each factor to zero

x-5=0                       4x+25=0
x=5                           x=- \frac{25}{4}

We need the positive value of x so we use x=5

Height = 5+1 = 6
Base = 4(5)+1 = 21

Brums [2.3K]

Answer:

c. [70.30, 74.70]

Step-by-step explanation:

Confidence interval is a range of values in which there is a specified probability that the value of a parameter lies within that range.

The confidence interval of a statistical data can be written as.

x+/-zr/√n .......1

Given;

Mean gain x = 72.5 cm

Standard deviation r = 4.5 cm

Number of samples n = 16

Confidence interval = 95%

z (at 95% confidence) = 1.96 (from the table)

Substituting the values we have into equation 1;

72.5 +/- 1.96×4.5/√16

72.5 +/- 2.20 cm

[70.30, 74.70]

Therefore, the 95% confidence interval is

[70.30, 74.70] cm
