nataly862011 [7]

Question:

<em>A research center poll showed that 78% of people believe that it is morally wrong to not report all income on tax returns. What is the probability that someone does not have this belief? </em>

<em>The probability that someone does not believe that it is morally wrong to not report all income on tax returns is . (Type an integer or a decimal.)</em>

Answer:

q = 0.22

Step-by-step explanation:

Given

Let p represent the given proportion

p = 78%

Required

Determine the probability that someone holds a contrary belief

Start by converting the given proportion to decimal

p = 78\%

p = \frac{78}{100}

p = 0.78

In probability, the sum of opposite probability is equal to 1

Represent the probability that someone holds a contrary belief with q

So;

p + q = 1

Make q the subject of formula

q = 1 - p

Substitute 0.78 for p

q = 1 - 0.78

q = 0.22

<em>Hence, the probability that someone does not believe is 0.22</em>

The length of the shorter side of a parallelogram is 29 cm. Perpendicular line segment, which goes through the point of intersec
Nata [24]
By definition, a parallelogram is merely a quadrilateral. Its key characteristics are having two sets of parallel sides. Consequently, it would have two sets of equal lengths, denoted as a and b. A perpendicular bisector is the red line in the picture that bisects length b into two lengths while creating a right angle. The area of a parallelogram is

A = bh, where
b is the side that meets with h
h is the perpendicular height of the parallelogram

Since h is not known, we have to solve it first through applying the pythagorean theorem.

h = √29^2 - 12^2 = 26.4 m

Thus,

A = (12 cm + 33 cm)(26.4 cm)
A = 1,188 square centimeters
