A study of 1000 randomly selected flights of a major airline showed that 820 of the flights arrived on time. What is the probability of a randomly selected flight not arriving on time?

a. 50/1
b. 9/50
c. 41/50
d. 1/4

Answers

Answer 1

Answer:

b. 9/50

Step-by-step explanation:

•the probability of the selected flight arriving on time: 820/1000 = 0.82

•find the probability of the flights not being selected by subtracting 0.82 from 1.00: 1.00-0.82=0.18

•now you look for the answer that equals to 0.18

50/1 =50 nope

9/50 =0.18 yes

41/50 =0.82 nope

1/4 = 0.25 nope

Answer:  0.92 feet (choice B)

You're close but not quite there. To get the answer, you divide 29.44 over 32

If you had 32 feet of banner and 32 students, then each student would get 32/32 = 1 foot. Since the length of the banner is smaller than the number of students, this means each student only gets a fraction of a foot. This fraction value is fairly close to 1 because 29.44 is close to 32.

Answer:

B: 0.92

Step-by-step explanation:

Divide the banner length by the amount of students

this is factoring quadratics with a leading coefficient: 5p to the 2 power - 52p + 20

Answers

Answer:

(-5p + 2)(-p + 10)

Step-by-step explanation:

[tex]5p^{2}[/tex]-52p + 20

(-5p + 2)(-p + 10)

You can double check this by using the distributive property..

-5p * -p = -5p^2

2*-p = -2p

10*-5p = -50p

10*2 = 20

-5p^2 + -2p + -50p + 20

Now we combine like terms and simplify

-5p^2 -52p + 20

So, we are correct

The table shows the highest and lowest golf scores for your cousin and your friend over the summer. Find the ranges of golf scores for your cousin and your friend. Who has the greater range of scores?

highest +6, +3
lowest -2, -3

Answers

Answer:

Cousin has a greater range of score.

Step-by-step explanation:

Range = Highest No. - Lowest No.

Range of cousin's score = +6 - (-2)

                                        = +6+2 = 8

Range of friend's score = -2 - (-3)

                                       = -2 + 3  = 1

Cousin has a greater range of score.

Find the dimensions of a rectangle with area 729000 m2 whose perimeter is as small as possible. (Give your answers in increasing order, to the nearest meter.)

Answers

Step-by-step explanation:

Area of a rectangle = Length * Width

A = LW

729000 =  LW .... 1

Perimeter of a rectangle P = 2L+2W

P = 2L+2W

From 1;

W = 729000/L

P = 2L + 2(729000/L)

P = 2L + 1458000/L

To minimize the perimeter, dP/dL = 0

dP/dL = 2 -  1458000/L²

2 -  1458000/L² = 0

2L² - 1458000 = 0

2L² = 1458000

L² = 729000

L = √729000

Length = 853.8m

W = A/L

Width = 729000/853.8

Width = 853.8

Hence the dimension to the nearest meter is 854m by 854m

Given that p(n)=4n2+4n−6 and q(n)=n2−5n+8, find (p−q)(3).

a. 26
b. 38

Answers

Answer:

(p-q) (3) = 40 The anwser is c

Step-by-step explanation:

If p(n)=4n2+4n−6 and q(n)=n2−5n+8.The value of (p−q)(3) will be 26. Option a is correct.

What is the equation?

An equation is a statement that two expressions, which include variables and/or numbers, are equal. In essence, equations are questions, and efforts to systematically find solutions to these questions have been the driving forces behind the creation of mathematics.

It is given that,

p(n)=4n²+4n−6 and q(n)=n²−5n+8

Substitute the given values and apply the arithmetic operation as,

(p−q) = (4n²+4n−6) - (n²−5n+8)

(p−q) =3n²-n+2

Put n = 3 for the given conditions,

(p−q)(3) =3(3)² - 3 +2

(p−q)(3) =27-3+2

(p−q)(3) =29-3

(p−q)(3) =26

Thus, if p(n)=4n2+4n−6 and q(n)=n2−5n+8.The value of (p−q)(3) will be 26. Option a is correct.

find the lowest number of four digits that can be divided by 22,36,and 42​

Answers

Answer:

find the lcm of 22,36,and 42

Step-by-step explanation:

lcm of 22 = 11 x 2

lcm of 36 = 2 x 2 x 3 x 3

lcm of 42 = 2 x 3 x 7

so the lcm of three numbers are 11 x 2 x 2 x 2 x 3 x 3 2 x 3 x 7 = 1000

Answer:

2,772

Step-by-step explanation:

First we find the LCM (Least common multiple) of the given numbers.

2 | 22, 36, 42

2 | 11, 18, 21

3 | 11, 9, 21

3 | 11, 3, 7

7 | 11, 1, 7

11 | 11, 1. 1

| 1, 1, 1,

LCM of 22, 36, 42 = 2*2*3*3*7*11 = 2,772

Thus, the lowest number of four digits that can be divided by 22,36,and 42 is 2772.

What is the product of 7×-6 1/8

Answers

Answer:

-42.875 or -42 7/8

Step-by-step explanation:

you can turn -6 1/8 into a decimal: -6.125 and multiply it with 7.

The product of the fraction 7 x -(6 1/8) is -42.875 or in fraction form -42 7/8.

We have expression: 7 x -(6 1/8).

First, write the mixed fraction into improper fraction as

Numerator = 8 x 6 + 1 = 49

Denominator = 8

Now, the product will be

7 x -(6 1/8)

= 7 x (-49/8)

= 7 x (-6.125)

= -42.875

An office building has 66000 of net income and sold for 550000. What is the rate of return

Answers

Answer:

The rate of return will be: 12%

Step-by-step explanation:

Given

Net income = 66000

As the building was sold for 550000

Market value = 550,000

Return can be calculated by dividing the market value by the net income using the formula

Return = Net income / Market value

           = 66000 / 550,000

           = 0.12  which is 12%

Therefore, the rate of return will be: 12%

How would you describe the relationship between the real zero(s) and x-intercept(s) of the function
f(x) =
3x(x - 1)
x2(x+3)(x + 1)
When you set the function equal to zero, the solution is x = 1; therefore, the graph has an x-intercept of (1,0).
O When you set the function equal to zero, the solutions are x = 0 or x = 1; therefore, the graph has x-intercepts at
(0, 0) and (1,0).
O When you substitute x = 0 into the function, there is no solution, therefore, the graph will not have any X-
intercepts.
Since there are asymptotes at x = -3, x = -1, and x = 0, the graph has no x-intercepts and therefore, no real
zeros.

Answers

The description of the relationship between the real zero(s) and x-intercept(s) of the function should be option A.

Relationship between the real zero(s) and x-intercept(s) of the function:

Since it is given that

f(x) = 3x(x - 1)

x2(x+3)(x + 1)

Also, the function should be set out and equivalent to zero when x = 1

and, the graph should have an x-intercept of (1,0).

Therefore, the option A is correct.

I am kind of stuck on this question could someone explain and answer this question I would really appreciate it :)

Answers

Answer:

First one

Step-by-step explanation:

Supplementary angles basically means which angles added together equals 180 degrees, 180 degrees is also a straight line.

So the answer would be the first one because both the angles added together is 180.

It’s the first one>>>40°+140°<<< because supplementary angles are two angles that should add up to 180° because 180°is the degree of a straight line. And the only one that adds up to 180 is the first one. Hope this helps!

A car and a truck leave the same intersection, the truck heading north at 60 mph and the car heading west at 55 mph. At what rate is the distance between the car and the truck changing when the car and the truck are 30 miles and 40 miles from the intersection, respectively?

Answers

Answer: -81

Step-by-step explanation:

Let x = the car moving towards west = 30

Let y = truck moving towards north = 40

dx/dt = -55

dy/dt = -60

We the use Pythagoras theorem to solve further where,

s² = x² + y²

s² = 30² + 40²

s² = 900 + 1600

s² = 2500

s =✓2500

s = 50

We then differentiate with respect to t, then we will have:

s² = x² + y²

2s ds/dt = 2x ds/dt + 2y dy/dt

50 ds/dt = (30 × -55) + (40 × -60)

50 ds/dt = -1650 - 2400

50 ds/dt = - 4050

ds/dt = -4050/50

ds/dt = -81
