Answer:

The number you would add to both sides of the equation to use the "Completing the Square" method would be 16.

Step-by-step explanation:

To find the number to add to both sides of an equation to complete the square, divide the first-degree term's coefficient by 2 and square your remainder. In this case, the coefficient of the first-degree term is -8. After dividing by 2 and squaring it, you'll get 16, so that is the number you must add to both sides of the equation in order to complete the square.

9th grade ..Plz solve this maths​
8_murik_8 [283]

since the polygon has 8 chambers the angle of one chamber = 360/8 = 45°

so the angle WOP = 45°

now drawing a imaginary line which seperates the triangleWOP into half

so the angle of imaginary line is 45/2 = 22.5

sin(theta) = opp/hyp

since WP (opp) is unknown. take as x

sin(22.5) = x/44

0.383×4 = x

x = 1.532 (app) = 1.5 cm

perimeter = 1.5 × 8

= 12 cm

area of triangle WOP = 2×1/2 ×bh = bh

= 4×1.5

= 6 cm²

so the area of regular polygon = 8× area of a triangle

= 48 cm²

Alternative hypothesis would be:

E. The true proportion of residents who have recently had the flu is greater than 0.05.

Step-by-step explanation:

Hypothesis testing is made to estimate the true population proportion<em> using the sample info. </em>

The purpose is to provide sufficient evidence to support that the true proportion of people who have recently had the flu is greater than 0.05. Therefore null and alternative hypotheses use this proportion.
