Find the area of the composite figure below.
6 9

Answer:

S = 6e²

I don't know what variable you're using here.

Step-by-step explanation:

There are 6 faces on a cube and they are all the same. Because of this, 6 is the coefficient in this equation.

A square's area can be found by squaring the side length (Which I'll represent with e). So e² is the variable.

Thus, the equation is S = 6e²

Answer:

$1,250

Step-by-step explanation:

The rate is 8%

= 8/100

= 0.08

Time is 6 months

= 1/2 year

Therefore the principal can be calculated as follows

Principal × (1+0.08(1/2) = 1300

Principal × 1+ 0.04 = 1300

Principal × 1.04= 1300

Principal= 1300/1.04

Principal = $1,250

Hence the principal is $1,250

Answer:

B, E, F

Step-by-step explanation:

they are linear because there are no fractions or exponents  

Answer:

B, E, F

Step-by-step explanation:

For a linear function, you can have x multiplied by a number, but you cannot have x multiplied by a variable. Also you can't have x in denominator or an exponent on x other than 1.

For a linear equation, y must equal a first degree polynomial or a constant.

Answer: B, E, F

b. Decision variables

Step-by-step explanation:

The decision variable is the variable that decides that what would be the output. It presents the final solution.

Since in the given situation it is mentioned that the Mike uses linear programming for formulating a problem now the choices that chose for minimize or maximize the value would be the decision variables

Hence, the correct option is b.

Objective function is a function used in linear programming (LP) so as to maximize or minimize.

Linear programming are system of linear constraints used to optimize or solve a problem. The problem is being solved by selecting the variables that would be used to maximize or minimize the objective function from a list of several objective functions.

This transformation takes a vector (x,y) and maps it to the vector (x+2, y+16). In other words, it moves the X coordinate of the vector 2 units to the right, and the Y coordinate of the vector is moved 16 units upwards.

If you would take a set of points and apply this transformation, you would see the entire set moving upwards and to the right, with no stretching ou rotating. This type of transformation is called a translation transformation.

Answer:

At least one of the population means is different from the others.

Step-by-step explanation:

ANOVA is a short term or an acronym for analysis of variance which was developed by the notable statistician Ronald Fisher. The analysis of variance (ANOVA) is typically a collection of statistical models with their respective estimation procedures used for the analysis of the difference between the group of means found in a sample. Simply stated, ANOVA helps to ensure we have a balanced data by splitting the observed variability of a data set into random and systematic factors.

In Statistics, the random factors doesn't have any significant impact on the data set but the systematic factors does have an influence.

Basically, the analysis of variance (ANOVA) procedure is typically used as a statistical tool to determine whether or not the mean of two or more populations are equal through the use of null hypothesis or a F-test.

Hence, the null hypothesis for an ANOVA is that all treatments or samples come from populations with the same mean. The alternative hypothesis is best stated as at least one of the population means is different from the others.

Answer:

117

Step-by-step explanation:

Hi, If you were to add 75 to 42, you would get 117. Since a triangle's angles all have to add up to 180, the last angle would be 63. However, you are looking for the outside angle, which would then just be 117. Hope this is right!

Answer:

50,001 people sent out the letter.

40,001 did not send it out

also can i get brainliest???

Step-by-step explanation:

780 people receive the letter before the chain ends.

9,220 people do not send out the letter.

We have,

In the given scenario, the chain letter starts with one person sending it to five others.

Each recipient of the letter has the option to either send it to five new recipients or not send it to anyone.

Let's analyze the chain letter progression:

The first person sends the letter to 5 recipients.

Each of those 5 recipients has the choice to send the letter to 5 new recipients or not send it.

If each of the 5 recipients sends the letter to 5 new recipients, we have a total of 5 x 5 = 25 new recipients.\

If any of the 5 recipients choose not to send the letter, they are out of the chain.

Now, we have 25 recipients who received the letter and have the same choice: send it to 5 new recipients or not send it.

If each of the 25 recipients sends the letter to 5 new recipients, we have a total of 25 * 5 = 125 new recipients.

If any of the 25 recipients choose not to send the letter, they are out of the chain.

This process continues until the chain ends.

To determine how many people receive the letter and how many do not send it out, we can observe the pattern:

After the first step, there are 5 recipients.

After the second step, there are 5 + (5 * 5) = 30 recipients.

After the third step, there are 5 + (5 * 5) + (5 * 5 * 5) = 155 recipients.

After the fourth step, there are 5 + (5 * 5) + (5 * 5 * 5) + (5 * 5 * 5 * 5) = 780 recipients.

We can see that the number of recipients follows a geometric progression with a common ratio of 5.

The formula for the sum of a geometric progression is:

[tex]Sum = a (r^n - 1) / (r - 1)[/tex]

Where:

a = initial term = 5

r = common ratio = 5

n = number of steps

We are given that the chain ends after 10,000 people send out the letter. Let's calculate the number of recipients:

[tex]Sum = 5 (5^4 - 1) / (5 - 1)[/tex]

= 5 (625 - 1) / 4

= 5 624 / 4

= 780

Therefore, 780 people receive the letter before the chain ends.

To find the number of people who do not send it out, we subtract the number of recipients from the total number of people who sent out the letter:

Number of people who do not send it out = Total number of people - Number of recipients

= 10,000 - 780

= 9,220

Therefore, 9,220 people do not send out the letter.

Thus,

780 people receive the letter before the chain ends.

9,220 people do not send out the letter.

Isolate the variable by dividing each side by factors that don't contain the variable.

______________________________

 - We subtract 2.9 from both sides because we need to get rid of any extra numbers on the opposite side of the equal sign. To do so, you do the opposite of what you see: We have a positive 2.9, so we subtract.

Equation at the end of Step 1:

 - We divide 3 from both sides because the 3 is attached to the variable and we need to get the variable alone. So to do so we have to divide by 3 on each side.
