Answer:

[tex]\dfrac{3}{4}[/tex]

Step-by-step explanation:

Given an event A

The probability of A occurring + The probability of A not occurring=1

or we can say:

P(A)+P([tex]A^c[/tex])=1, where [tex]A^c[/tex] is the complement of A.

In the given problem, if the probability of selecting a pink rose is 1/4.

(I want to presume its 1/4 not 14 since probability cannot be greater than 1)

We then have:

P(selecting a pink rose) + P(not selecting a pink rose)=1

P(not selecting a pink rose)=1-P(selecting a pink rose)

[tex]=1-\dfrac{1}{4}\\\\=\dfrac{3}{4}[/tex]

Step-by-step explanation:

Answer:

He played 7 arcade games.

Step-by-step explanation:

The amount paid in relation to the number of games played can be modeled by a linear function in the following format:

[tex]A(n) = F + gn[/tex]

In which F is the flat rate and g is the price of each game.

Flat fee of $30 but he had to pay $2 for each arcade game he played.

This means that [tex]F = 30, g = 2[/tex]

So

[tex]A(n) = 30 + 2n[/tex]

Jason spent $44. How many arcade games did he play?

This is n for which A(n) = 44. So

[tex]A(n) = 30 + 2n[/tex]

[tex]44 = 30 + 2n[/tex]

[tex]2n = 14[/tex]

[tex]n = \frac{14}{2}[/tex]

[tex]n = 7[/tex]

He played 7 arcade games.

Original formula:

P/2-5 when p=14

You just need to plug in 14 in place of where the variable p is at. This is called substitution.

14/2-5

By the rules of PEMDAS, we will execute 14/2 first. (7)

7-5

2 is your final answer.

Answer:

[tex]20943.96 ft^3[/tex]

Step-by-step explanation:

The silo is shaped as a cylinder with a hemisphere on top of it.

We need to find the volume of the shape.

The volume of a cylinder is given as:

[tex]V = \pi r^2h[/tex]

where r = radius

h = height

The volume of a hemisphere is given as:

[tex]V = \frac{2}{3} \pi r^3[/tex]

where r = radius

Therefore, the joint volume of both shapes is:

[tex]V = \pi r^2h + \frac{2}{3} \pi r^3[/tex]

The height of the silo is 60 and the diameter is 20.

This means that the radius is 10.

The cylindrical part of the silo and the hemispherical part have the same radius, 10.

The volume of the silo is:

[tex]V = \pi * 10^2 * 60 + \frac{2}{3} * \pi * 10^3\\ \\V = 18849.56 + 2094.40\\\\V = 20943.96 ft^3[/tex]

The volume of the silo is [tex]20943.96 ft^3[/tex]

Answer:

19.5

Step-by-step explanation:

there are two middle values in this data set so you have to add and divide them. 18+21=39

39/2= 19.5

hope this helps ! :)

Answer:

19.5

Step-by-step explanation:

middle is 18 and 21 so we need to take the average of these  2 numbers

18+21=39

39/2=19.5

Answer:

D. Vertex: (3, -1); zeros: (2,0), (4,0), y-intercept: (0,8)

Step-by-step explanation:

I used the desmos graphing calculator. Just plug in your equation and it should be pretty easy to find these points

Answer:

Vertex is (3,-1)  zeros ( 4,0) (2,0) and y intercept (0,8)

Step-by-step explanation:

y = x^2 - 6x+8

Factor

y = (x-4) (x-2)

Set = 0 to find the zeros

0 = (x-4) (x-2)

Using the zero product property

x-4 = 0    x-2 =0

x=4   x=2

The vertex is 1/2 way between the zeros

(4+2)/2 = 6/2 = 3

y = (3-4) (3-2)

  -1 (1)

y = -1

Vertex is (3,-1)

The y intercept is at x=0

y = 0-0+8

y =8

Answer:

Step-by-step explanation:

Guven two prime numbers to be 31/x and 71/x, if their sum is 10 as given;

3x + 71/x = 10 then to find the value of x, the following steps must be taken;

Step 1

Find the LCM of the given equation;

3x + 71/x = 10

[tex]\frac{3x^{2}+71 }{x} =10\\[/tex]

Step 2:

Cross multiplying;

[tex]3x^{2} +71=10x\\3x^{2} -10x+71 =0\\[/tex]

Using the general formula to get the value of x;

x = -b±√b²-4ac/2a

a=3, b=-10, c=71

= 10±√(-10)²-4(3)(71)/2(3)

= 10±√100-852/6

= 10±√-752/6

= 10±27.4i/6

= 10+27.4i/6 or 10-27.4i/6

x = 5/3+27.4i/6 or 5/3-27.4i/6

Since the values of x are real values then, our answer will be the real part of the complex number gotten.

x = 5/3

Answer:

11 cm

Step-by-step explanation:

The strip of paper is 66 cm and it is folded into 6 different parts. It is used to form a model of a honeycomb cell.

To find the length of one side of the model, all we have to do is divide 66 cm by 6. That is:

66 / 6 = 11 cm

The length of one side of the model is 11 cm.

Answer: 16

Step-by-step explanation:

[tex]x^2-8x+c[/tex]

Let's complete the square.

[tex]c=(\frac{b}{2})^2[/tex]

[tex]c=(\frac{-8}{2})^2[/tex]

[tex]c=(-4)^2\\ c=16[/tex]

The value c that completes the square for x²-8x+c is,

c = 4

We have to give that,

An equation is,

⇒ x² - 8x + c

Now, Complete the quadratic equation to square,

⇒ x² - 8x + c

⇒ x² - 2×2²×x + 4

⇒ x² - 8x + 4

⇒ (x - 2)²

Hence, The value c that completes the square for x²-8x+c is,

c = 4

Answer:

5 7/12

Step-by-step explanation:

To get the total amount of nuts used in all, what we do is to add all the fractions together

But we convert them to mixed fraction to make the work easier;

2 3/4 = 11/4

1 2/3 = 5/3

1 1/6 = 7/6

Adding all, we have;

11/4 + 5/3 + 7/6 = (33+ 20 + 14)/12 = 67/12 = 5 7/12

Answer:

4 7/12

Step-by-step explanation:

2 3/4 + (1 2/3 + 1/6) = 2 3/4 + (1 4/6 + 1/6) = 2 3/4 + 1 5/6 = 2 9/12 + 1 10/12 = 3 19/12 = 4 7/12

Answer:

A = 222 in²

Step-by-step explanation:

A = 2(wl+hl+hw)             Use this equation to find the surface area of the rectangular prism

A = 2(5*12 + 3*12 + 3*5)    Multiply

A = 2(60 + 36 + 15)            Add in the parentheses

A = 2(111)                             Multiply

A = 222 in²

Answer: 74.93

Step-by-step explanation:   if you heard of the line equals line method this should be able to help you.  

299.75                     25%

---------------=------------------  

$1199                     100%      

so you cross multiply 1199 and 25 and then divide it by 100.   which would be 299.75 that is the price per 1 year then you divide that value by 4 and that will be your answer.  

299.75 divided by 4= 74.93  

hope this helps

Answer:

379.37

Step-by-step explanation:

I just did it the manual way

1199-25%=899.25

(25% of 1199 is 299.75)

899.25-25%=674.44

(25% of 899.25 is 224.81)

674.44-25%=505.83

(25% of 674.44 is 168.61)

505.83-25%= 379.37

(25% of 505.83 is 126.5)

I just took a test with this question

Answer: 68 adult tickets were sold and 78 child tickets were sold.

Step-by-step explanation:

a + c = 146 where a is the number of adults tickets sold and c is the numbe rof child tickers sold.

5.60 a+ 8.80c= 1067.20

    a    + c = 146

5.60a  + 8.80c = 1067.20 solve by elimination.

a=68

c =78

Answer:

Step-by-step explanation:

Answer:

The volume of the solution with 20% acid is 27 gallons and the one with 10% acid is 18 gallons

Step-by-step explanation:

Myra needs to mix "x" gallons of the solution with 20% and "y" gallons of the solution with 10%. The volume of the final solution must be 45 gallons, therefore:

x + y = 45

The concentration of acid of the final solution is:

0.2*x + 0.1*y = 45*0.16

0.2*x + 0.1*y = 7.2

Therefore we have a system of equation:

x + y = 45

0.2*x + 0.1*y = 7.2

We need to multiply the first equation by -0.1:

-0.1*x -0.1*y = -4.5

0.2*x + 0.1*y = 7.2

We now sum both equation:

0.1*x = 2.7

x = 2.7/0.1 = 27 gallons

y = 45 - 27  = 18 gallons

Answer:

28 is less than or equal to x

Step-by-step explanation:

28 is less than or equal to x

Answer:

0.52 cubic inches

Step-by-step explanation:

Given: circumference of a basketball is 31.4 inches.

[tex]\pi =3.14[/tex]

To find: basketball's volume to the nearest cubic inches

Solution:

circumference of a basketball (sphere) = 6.28(radius)

Also, circumference of a basketball = 31.4 inches.

So, 6.28(radius) = 3.14

radius = [tex]\frac{3.14}{6.28}=\frac{1}{2}[/tex] inch

Volume of the basketball (sphere) = [tex]\frac{4}{3}(\pi )(radius)^3=\frac{4}{3}(3.14)(\frac{1}{2})^3=0.52\,\,cubic\,\,inches[/tex]
