Answer: basically simplifying is this

Step-by-step explanation:

2x+4x+8x+3y+2y+9y

we can simplify that to 14x+14y by adding like terms.

or

3(2x+4)

this can be simplified to 6x+12 by distributive property (multiply everything in the parenthesis by 3)

Step-by-step explanation:

If the question is how much sugar contains pie, then do it like this:

6:3=2

So in one container you have 2 pounds of sugar. And if you use 1 container for a pie you will use : 2 pounds of sugar for pie.

If question is how much sugar does he have after that, it would be:

6-2=4 pounds of sugar or

3-1= 2 containers of sugar

And the tables will help you and so will this.

Step-by-step explanation:

Look at the value for question of getting an answer right and you have to do a table that looks like this attached  

4 games at 2/3 chance for each = 16/27

We look at 1/3 x 1/3 = 11/ 20

we look at 2/3 x 2/3 = 0.444 = 22/50 = 11/25

The other two games are

1/3 x 2/3 = 0.22 + 0.22 = 0.44

0.44  =  11/25

+ 3/20

= 16/27

It wont be as complicated as that. But im sure this will help.

Solution :

It is given that a large institution is preparing food menus which contains foods A as well as B.

Each lunch provides :

10 units of carbohydrates

6 units of fats

7 units of proteins

The food from A cost = $0.12 per ounce

And food from B cost = $0.08 per ounce

Objective function :

[tex]$C= 0.12x+0.08y$[/tex]

Constraints : [tex]$x\geq 0, y \geq 0, x+y \geq 6, 2x+y \geq 10, x+y \leq 7$[/tex]

Domain : [tex]$3 \leq x\leq 7$[/tex]

Range : [tex]$0\leq y\leq4$[/tex]

Answer:

Step-by-step explanation:

Let A ≤ B ≤ C

largest angle is 16 less than 4 times the smallest angle

C = 4A-16

middle angle is 7 more than half the measure of the largest angle

B = C/2 + 7

A+B+C = 180°

A = 28 ⅐°

B = 55 2/7°

C = 96 4/7°

Answer:

He will have to pay $1,650 in interest at the end of 3 years.

Step-by-step explanation:

This is a simple interest problem.

The simple interest formula is given by:

[tex]E = P*I*t[/tex]

In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.

After t years, the total amount of money is:

[tex]T = E + P[/tex]

Anvi borrowed $5,000 from a bank at a flat interest rate of 11% per year for a 3-year period.

This means that [tex]P = 5000, I = 0.11, t = 3[/tex]

How much interest does she have to pay the bank at the end of 3 years?

[tex]E = P*I*t = 5000*0.11*3 = 1650[/tex]

He will have to pay $1,650 in interest at the end of 3 years.

Answer:

Infants whose brains are temporarily deprived of oxygen - Subject of investigation

Usual care or whole-body cooling ET - Explanatory variable

Survival without brain damage - Response variable

Step-by-step explanation:

The subject of investigation are the set of participants who are used in a research study. Based on the scenario described above, 208 infants whose brains were temporarily deprived of oxygen as a result of complications at birth were researched. And these sentence gives us the subject of investigation.

The Explanatory variable can also be called the independent variable which are the variables which causes changes behavior or output produced by the response variable. The usual care and whole body cooling are the two independent temperature options subjects are assigned subjected to.

The response variable also called the predicted variable gives the outcome or effect of the the Explanatory variable on the subject of investigation.

Answer:

  g(n) = 2n +49

Step-by-step explanation:

The recursive formula tells you this is an arithmetic sequence with first term 51 and common difference 2. The explicit formula for such a sequence is ...

  an = a1 +d(n -1) . . . . first term a1, common difference d

Using the sequence values, we have ...

  g(n) = 51 +2(n -1)

  g(n) = 2n +49 . . . . . simplified

Answer:

Step-by-step explanation:

r = 1.5 ft

h = 15 ft

π = 3.14

Volume = πr²h

             = 3.14 * 1.5 *1.5 *15

             = 1.5.975 cubic feet

The radius of a cylindrical construction pipe is 1.5 ft. If the pipe is 15 ft long, what's the volume ?

[tex] \bullet [/tex] Radius (r) of a cylindrical construction pipe is 1.5 ft.

[tex] \bullet [/tex] Height (h) of a cylindrical construction pipe is 15 ft.

Volume of a cylindrical construction pipe.

We know,

Formula of Volume of cylinder is πr²h.

So, Volume = 3.14 × (1.5)² × 15

Volume = 3.14 × 1.5 × 1.5 × 15

Volume = 105.975 cubic ft.

Answer:

I would make sure to note keywords in the problem/question such as (percent) off, (percent) tax, etc. These words can determine if the original number will become higher or lower after the percent is applied to the original number. For example, if there is a price for a t-shirt of $15, and there is a tax of 13%, the original price will increase. On the other hand, if there is a sale for pants at the local department store and you are buying a pair of pants that cost $25 with the sale being 10% off, the price will decrease.

Answer:

The necessary sample size is of 5683.

Step-by-step explanation:

In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.

[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

In which

z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].

The margin of error is:

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

90% confidence level

So [tex]\alpha = 0.1[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.1}{2} = 0.95[/tex], so [tex]Z = 1.645[/tex].

Past surveys reveal the 30% of tourists going to Las Vegas to gamble spend more than $1,000.

This means that [tex]\pi = 0.3[/tex]

The estimate is to be within 1% of the population proportion. What is the necessary sample size?

A sample size of n is necessary. n is found when [tex]M = 0.01[/tex]. So

[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]

[tex]0.01 = 1.645\sqrt{\frac{0.3*0.7}{n}}[/tex]

[tex]0.01\sqrt{n} = 1.645\sqrt{0.3*0.7}[/tex]

[tex]\sqrt{n} = \frac{1.645\sqrt{0.3*0.7}}{0.01}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.645\sqrt{0.3*0.7}}{0.01})^2[/tex]

[tex]n = 5682.6[/tex]

Rounding up:

The necessary sample size is of 5683.

Answer:

r=7

Step-by-step explanation:

74000=28000(1+r/12)^12(14)

divide 74000 by 28000, and cancel out 28000.

1.00580=1+r/12

(100) .06962=r

r = 6.96198

the 6 after the 9 rounds 9 to 0, which rounds the 6 to 7

r=7
