In a Gallup poll of randomly selected adults, 66% said that they worry about identity theft. For a group of 1013 adults, the mea
Kazeer [188]

Answer:

Mean = 344

Step-by-step explanation:

Given

Population =  1013

Let p represents the proportion of those who worry about identity theft;

p = 66\%

Required

Mean of those who do not worry about identity theft

First, the proportion of those who do not worry, has to be calculated;

Represent this with q

In probability;

p + q = 1

Make q the subject of formula

q = 1 - p

Substitute p = 66\%

q = 1 - 66\%

Convert percentage to fraction

q = 1 - 0.66

q = 0.34

Now, the mean can be calculated using:

Mean = nq

Where n represents the population

Mean = 1013 * 0.34

Mean = 344.42

Mean = 344 (Approximated)

Line JK passes through points J(–4, –5) and K(–6, 3). If the equation of the line is written in slope-intercept form, y = mx + b
garri49 [273]

Answer:

b = - 21

Step-by-step explanation:

calculate m using the gradient formula

m = ( y₂ - y₁ ) / ( x₂ - x₁ )

with (x₁, y₁ ) = (- 4, - 5) and (x₂, y₂ ) = (- 6, 3)

m = \frac{3+5}{-6+4} = \frac{8}{-2} = - 4

y = - 4x + b ← is the partial equation

to find b substitute either of the 2 given points into the partial equation

using (- 4, - 5 ), then

- 5 = 16 + b ⇒ b = - 5 - 16 = - 21
