===================================================

Explanation:

Let's say this population had 1000 people. You can pick any number you want, but I'm going for some nice big round number to work with.

The proportion of smokers is 0.3, which means 0.3*1000 = 300 people in this population are smokers and 1000-300 = 700 are nonsmokers.

Of the 300 people who do smoke, 40% of them lie on the application. This means 0.40*300 = 120 people lied. These 120 people say they don't smoke, but in fact they do smoke.

So if we were to survey this population, then 700+120 = 820 people would say they don't smoke

Only considering the people who write "don't smoke" on the survey, which is that 820 figure, 700 of them are true nonsmokers. Therefore, the probability we want is 700/820 = 0.8537 approximately

so 2 to 1       2:1

#1

(56,7) is the co-ordinate of point B.

#2

(56,7)

It means that the ball has travelled 56yards .it is at the height of 7ft.

Answer:

(56,7) is the answer of this questions

Answer:1/10

Step-by-step explanation:so easy

The probability that the students she selects are both boys is 1/10.

Given is that a math class has 4 girls and 1 boy in the seventh grade and 5 girls and 5 boys in the eighth grade. The teacher randomly selects a seventh grader and an eighth grader from the class for a competition.

The probability that the students she selects are both boys -

P{E} = P{1} x P{2}

P{1} : randomly selecting a seventh grader as a boy.

P{2} : randomly selecting a eight grader as a boy.

We can write -

P{1} = n{f}/n{s} = 1/5

P{2} = n{f}/n{s} = 5/10 = 1/2

P{E} = P{1} x P{2}

P{E} = 1/5 x 1/2

P{E} = 1/10

Therefore, the probability that the students she selects are both boys is 1/10.

Step-by-step explanation:

ur are choosing correct option as,

W = Y ( 90° given )

VW = YZ ( as both are || to eachother so their length is same )

angle X = X ( vertically opposite angle)

therefore, ∆WVX = ∆ZYX are congruent according to SAS congruency rule/criteria.

hope this answer helps you dear..take care and may u have a great day ahead and also ur exam/test goes well!.

Step-by-step explanation:

the price of:

3.17 pounds of pears = 3.17 × 0.99

= $3.14

1.45 pounds of oranges = 1.45 × $1.19 = $1.73

1.77 pounds of grapes = 1.77 × $1.29 =$2.28

so , the total bill = 3.14+ 1.73+ 2.28 = $7.15

Find prices of all

Answer:

-43x - 5

Step-by-step explanation:

−3x + 5 (−8x −1)

First, distribute 5 into the parenthesis:

= −3x + 5 (−8x −1)

= -3x - 40x -5

Combine like terms:

= -43x - 5

Answer:

$ 80,000

Step-by-step explanation:

2/5 + 1/3 = (6 + 5)/15 = 11/15

15/15 - 11/15 = 4/15

4/15 of 300,000

4/15 x 300,000 = 1,200,000/15 = 80,000

Step-by-step explanation:

I know but I m feeling bore

d/dx cot(x) = -csc²(x)

d/dx sin(x) = cos(x)

So, if f(x) = 4 cot(x) + 10 sin(x), then

f '(x) = -4 csc²(x) + 10 cos(x)

Answer:

  g(x) = √(x -5) +7

Step-by-step explanation:

To translate the graph of f(x) by h units horizontally and k units vertically, the function is transformed to ...

  g(x) = f(x -h) +k

To translate f(x) = √x by 5 units horizontally and 7 units vertically, the function is transformed to ...

  g(x) = √(x -5) +7
