Answer: 13.64%

Step-by-step explanation:

Alyssa estimates that the gym can hold 660 students even though it can hold 750.

Her percent error is calculated by:

= (Actual seats - Estimated seats) / Estimated seats

= (750 - 660) / 660

= 90 / 660

= 0.1364

= 13.64%

Given:

The LCM of two numbers is 14 times their HCF.

The sum of LCM and HCF is 600.

One number is 280.

To find:

The other number.

Solution:

Let HCF of two numbers be x.

The LCM of two numbers is 14 times their HCF.

LCM = 14x

The sum of LCM and HCF is 600.

[tex]14x+x=600[/tex]

[tex]15x=600[/tex]

[tex]x=\dfrac{600}{15}[/tex]

[tex]x=40[/tex]

So, HCF = 40 and the LCM is

[tex]LCM=14(40)[/tex]

[tex]LCM=560[/tex]

We know that, if a and b are two numbers, then

[tex]a\times b=LCM(a,b)\times HCF(a,b)[/tex]

One number is 280.

[tex]280\times b=560\times 40[/tex]

[tex]b=\dfrac{560\times 40}{280}[/tex]

[tex]b=2\times 40[/tex]

[tex]b=80[/tex]

Therefore, the other number is 80.

Total number of orders served by Maya, Ahmad and Joe on Moday = 75

Let the number of orders Maya served be x.

Then :

Number of orders Joe served = 2x

Number of orders Ahmad served = x - 5

This can be written in an equation as :

[tex] \tt \: 2x + x - 5 + x = 75[/tex]

[tex] = \tt 4x - 5 = 75[/tex]

[tex] = \tt 4x = 75 + 5[/tex]

[tex] = \tt 4x = 80[/tex]

[tex] = \tt \: x = \frac{80}{4} [/tex]

[tex] = \tt \: x = 20[/tex]

Which means :

Number of orders Joe served :

= 2 × 20

= 40

Thus, Joe served 40 orders.

Number of orders Maya served = 20

Number of orders Ahmad served :

= 20 - 5

= 15

Thus, Ahmad served 15 orders.

delta math

Answer:

The variables in a study of a cause-and-effect relationship are called the independent and dependent variables. The independent variable is the cause. Its value is independent of other variables in your study. The dependent variable is the effect. Its value depends on changes in the independent variable.

Answer:

The solution to the system of equations is:

The graph is attached below.

Step-by-step explanation:

Given the system of equations

[tex]2y = 2x - 8[/tex]

[tex]2x + y = 5[/tex]

Let us solve the system of equations using the elimination method

[tex]\begin{bmatrix}2y=2x-8\\ 2x+y=5\end{bmatrix}[/tex]

Arrange equation variables for elimination

[tex]\begin{bmatrix}2y-2x=-8\\ y+2x=5\end{bmatrix}[/tex]

Multiply y + 2x = 5 by 2:  2y + 4x = 10

[tex]\begin{bmatrix}2y-2x=-8\\ 2y+4x=10\end{bmatrix}[/tex]

subtracting the equations

[tex]2y+4x=10[/tex]

[tex]-[/tex]

[tex]\underline{2y-2x=-8}[/tex]

[tex]6x=18[/tex]

solve 6x = 18 for x

[tex]6x=18[/tex]

Divide both sides by 6

[tex]\frac{6x}{6}=\frac{18}{6}[/tex]

simplify

[tex]x=3[/tex]

For 2y - 2x = -8  plug in x = 3

[tex]2y-2\cdot \:3=-8[/tex]

[tex]2y-6=-8[/tex]

Add 6 to both sides

[tex]2y-6+6=-8+6[/tex]

Simplify

[tex]2y=-2[/tex]

Divide both sides by 2

[tex]\frac{2y}{2}=\frac{-2}{2}[/tex]

Simplify

[tex]y=-1[/tex]

Therefore, the solution to the system of equations is:

The graph is attached below.

Answer:

$45

Step-by-step explanation:

THIS IS THE COMPLETE QUESTION BELOW;

For a walk-a-thon a sponsor committed to give you a flat fee of $5 plus $2 for every mile you walk. If you walk for 20 miles, what is the total amount you will collect from your sponsor at the end of the walk-a-thon?

$5 was given for participants of the walk-a-thon.

$2 was given for every miles won

Then, for "y" number of miles, the the amount that can be won is ( 2×y)= 2y

The Total amount that can be given

= (5 + 2y)

Where "y" is the miles value

Then, if you walk for 20 miles, The Total amount that can be given

= 5 + 2(20)

= 5+ 40

= $45

Answer:

Please check the explanation.

Step-by-step explanation:

Given

P(Z > 1.96)

To determine

What probability expression is equivalent to P(Z > 1.96)

Suppose Z is a standard normal variable.

Therefore,

P(Z > 1.96) = 1 - P(Z ≤ 1.96)

solving

                 = 1 - Ф(1.96)

                 = 1 - 0.9750

                 = 0.0250

The probability of the expression being equivalent to P(z > 1.96) is calculated as 0.0250.

The z-score is a numerical measurement used in statistics of the value's relationship to the mean of a group of values, measured in terms of standards from the mean.

The given information is P(z > 1.96)

Let z is a standard normal variable. Then we have

P(z > 1.96) = 1 – P(z ≤ 1.96)

P(z > 1.96) = 1 – 0.9750

P(z > 1.96) = 0.0250

Step-by-step explanation:

you can pick between 1/4 or 0.25 they both equal 3

Answer:

False

Step-by-step explanation:

1/8 = 0.125

12 = 12

0.125 and 12 do not match; the expression is false.

Answer:

3.5%

Step-by-step explanation:

Given data

A=$6225

P=$5000

T= 7years

R=???

Simple interest

A=P(1+rt)

substitute

6225=5000(1+7r)

6225=5000+35000r

collect like terms

6225-5000=35000r

1225=35000r

r= 1225/35000

r=0.035

Hence the rate is 0.035*100= 3.5%

Answer: 11

Step-by-step explanation:

Based on the information that have been given in the question, we can use the information to form an inequality which goes thus:

5 + 9.95h < 125

9.95h < 125 - 5

9.95h < 120

h < 120/9.95

h < 12.06

h < 12

Therefore since h is less than 12, the greatest number of hat that can be ordered will be 11.

A sampling distribution of the sample proportion with n = 20 and p = 0.8

Step-by-step explanation:

We are given that

The probability of tails of a weighted coin, p=0.8

n=20

We have to find the type of distribution is simulated if this procedure repeated 75 times .

Random variable is a proportion of number of tails therefore, type of distribution is   sampling distribution of the sample proportion.

We have n=20 and p=0.8

Hence, we can say that type of distribution is simulated is given by
