i need help with 14 and 16​

Answer:

5/8

Step-by-step explanation:

Total pitches thrown = 384

Number of fastballs = 240

To obtain the decimal that should be used to update report ;

Take the ratio of fastballs to the total number of pitches :

Fastballs / total number of pitches

240 / 384

= 30 / 48

= 10 / 16

= 5 / 8 (lowest term)

Incomplete question:

A fair die is rolled one. What is P(roll less than 4)? If necessary, round your answer to 2 decimal places.

Answer:

P(roll less than 4) = 0.50

Step-by-step explanation:

First, we need to list the sample space.

[tex]S = \{1,2,3,4,5,6\}[/tex]

From the above, we have that:

[tex]n(S) = 6[/tex] i.e. total rolls

Represent Rolls less than 4 with L4; So,

[tex]L4 = \{1,2,3\}[/tex]

[tex]n(L4) = 3[/tex] i.e. number of rolls less than 4

The required probability is calculated as:

[tex]Probability = \frac{n(LA)}{n(S)}[/tex]

[tex]Probability = \frac{3}{6}[/tex]

[tex]Probability = 0.50[/tex]

Answer: 0.50

Answer:

well it isn't in the solution it would be an inequality that doesn't have a line under it

if it has a line under the inequality then it would be included in the solution

Answer:

the answer that i got was D

Step-by-step explanation:

i did -12x+6

the X is the numbers that they give you so

you would do -12*-8+6 = 102 which is bigger than 8

then you would do -12*-5+6= 66 which is bigger than 8

and last but not least you do -12*-1+6=18 which is bigger than 8

Answer:

The correct answer is the square root of 2.

Step-by-step explanation:

Irrational numbers can not be put into fractions, so it is not the first one. 3.3333 is also 3 1/3 and the square root of 289 is rational.

Answer:

Error in step (5)

Step-by-step explanation:

Steps                             Statements

    1                            cos(2x) = 2cosx - 1

    2                           Let (2x) = θ

    3                           Then x = [tex]\frac{\theta }{2}[/tex]

    4                           cos(θ) = [tex]2\text{cos}^2{\theta}-1[/tex]

    5                           cos(θ) + 1 = [tex]2\text{cos}^2{\frac{\theta}{2}}[/tex]

    6                            [tex]\frac{1+\text{cos}\theta }{2}=cos^{2}\frac{\theta }{2}[/tex]

    7                            [tex]\text{cos}^{2}\frac{\theta }{2}=\frac{1+\text{cos}\theta }{2}[/tex]

    8                            [tex]\text{cos}(\frac{\theta }{2})=\pm \sqrt{\frac{1+cos(\theta)}{2} }[/tex]

By comparing the solution given in the picture attached with the solution above,

Step 5 has error.

There should be [cos(θ) + 1 = [tex]2\text{cos}^2({\frac{\theta}{2}})[/tex]] in place of [-1 + cos(θ) = [tex]2\text{cos}^2({\frac{\theta}{2}})[/tex]]

Answer:

For 1 cup of  pineapple 1 .5  cups of strawberries are used.

Step-by-step explanation:

This question can be solved by using ratios

Strawberry       :      Pineapple

1     cup              :          2/3 cup

x cup                  ;            1 cup

Using the cross product rule

2/3 * x= 1*1

x= 1*1 ÷ 2/3

x= 1*3/2= 1 1/2= 1.5

For 2 cups of pineapple 3 cups of strawberries are used.

For 1 cup of  pineapple 1 .5  cups of strawberries are used.

For 3 cups of pineapple 4.5 cups of strawberries are used.

Answer:

We know that for a rectangle of length L and width W, the perimeter is:

P = 2*L + 2*W.

In this case, we know that:

P = 85ft = 2*L + 2*W

L = 2*(x + 16)

W = (3*x - 1)

(where i guess that these units are in ft )

This is a system of equations:

Then we can replace the second and third equation into the first one, and get:

85 = 2*2*(x + 16) + 2*(3x - 1)

And solve this for x, we will get:

85 = 4x + 64 + 6x - 2

85 - 64 + 2 = (4 + 6)*x

23 = 10*x

23/10 = x

2.3 = x

Then the measures of the rectangle are:

L = 2*(x + 16) = 2*(2.3 + 16) = 36.6

W = (3*x - 1) = (3*2.3 - 1) = 5.9

The length of the rectangle is 36.6 feet, (and the width is 5.9 feet)

It is 1, because you should use the order of pemdas. PEMDAS tells you what to calculate first, second, third and so on, until the calculation is complete.

PEMDAS is an acronym for the words parenthesis, exponents, multiplication, division, addition, subtraction.

Answer:

Step-by-step explanation:

let the total cost be y

and the number of minutes be m

Plan A

$20 and additional 6cent

6cent to dollar =$0.06

the linear expression is given as

y=20+0.06m---------1

Plan B

$31.5 and additional 4cent

6cent to dollar =$0.04

the linear expression is given as

y=31.5+0.04m----------2

Equating 1 and 2 we can find m

20+0.06m=31.5+0.04m

20-31.5=0.04m-0.06m

-11.5=-0.02m

m=11.5/0.02

m=575

therefore m>575

Step-by-step explanation:

Y= how many pages he has left to read

Answer:

900-60x

Explain:

900 total minus 60 times the amount of days equals the amount of pages left

Answer:

40 minutes

Step-by-step explanation:

Time at which Aaron gets home from school = 4:30 PM

Bedtime for Aaron = 9:00 PM

Total available for Aaron = 9:00 - 4:30 = 4 hr 30 minutes

To convert minutes to hours, we need to divide by 60.

Time spent in playing football = 90 minutes = [tex]\frac{90}{60} = 1\ hr\ 30\ minutes[/tex]

Time spent eating dinner = 35 minutes

Time spent in doing homework = 1 hr 45 minutes

Total time spent = 1 hr 30 minutes + 35 minutes + 1 hr 45 minutes = 2 hr 110 minutes = 3 hr 50 minutes

Time left for Aaron to play video games = 4 hr 30 minutes - 3 hr 50 minutes = 40 minutes

Given :

A 7-inch candle burns at a rate of 2 inches an hour.

To Find :

An equation represents the relationship between y, the height of the candle in inches, and x, the number of hours the candle burns.

Solution :

We know, linear equation is given by :

[tex]y = mx + c[/tex]

At x = 0 -> y = 7

So,

7 = m(0) + c

c = 7       .....1 )

At x = 1 -> y = 5

So,

5 = m(1) + c

c + m = 5   .....2 )

Solving equation 1 and 2 , we get :

m = -2 and c = 7

Therefore, equation is given by y = -2x + 7 .

Hence, this is the required solution.

Answer:7–2x

Answer:

Step-by-step explanation:

if she has 3 dogs and each gets a pound of food. Each can if food has .75 pounds in it then you would times that by then you would get 4 cans of food.

Shawna wants to leave 1 pound of food per dog, and she has 3 dogs. So, she needs 3 pounds of food in total.

In mathematics, divides left-hand operands into right-hand operands in the division operation. The primary purpose of the division is to generate equal groupings or to determine how many people are in each category after a fair distribution.

For example 4/2 = 2

A can of dog food has 0.75 pounds of food.

To determine the number of cans of food Shawna should leave, divide the total amount of food she needs (3 pounds) by the amount of food in each can (0.75 pounds).

⇒ 3 pounds / 0.75 pounds/can = 4 cans of food.

Therefore, Shawna should leave 4 cans of food for her 3 dogs.

Step-by-step explanation:

Answer:

[tex]m=\frac{6}{5}[/tex]

Step-by-step explanation:

Slope Formula: [tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]

Simply plug in the 2 coordinates into the slope formula to find slope m:

(2, -5)

(7, 1)

[tex]m=\frac{1-(-5)}{7-2}[/tex]

[tex]m=\frac{1+5}{5}[/tex]

[tex]m=\frac{6}{5}[/tex]

Given:

One solution to a quadratic equation is [tex]x=-\dfrac{5}{3}[/tex].

To find:

The true statement about remaining solutions.

Solution:

We know that, number of solution to a quadratic equation is 2.

According to the complex conjugate root theorem, if a complex number x+iy is a root of an equation then its conjugate x-iy is also a root of that equation.

It means, the complex roots are in the pair of two.

Using complex conjugate root theorem, a quadratic equation has either 0 complex roots or 2 complex roots.

One solution to a quadratic equation is [tex]x=-\dfrac{5}{3}[/tex], which is real.

There are no complex solutions and there is exactly one more real solution.

Therefore, the correct options are A and E.
