Answer:

simplify parenthesesevaluate the exponential termdivide 40/8multiply 8*2add 5+9add 14+16

Step-by-step explanation:

  40/8+3^2+(15-7)*2 . . . . given

The order of operations tells you to start by evaluating expressions in parentheses. Here, that is the subtraction of 7 from 15.

  40/8 +3^2 +8*2 . . . . (15-7) = 8

Then you evaluate exponential terms.

  40/8 +9 +8*2 . . . . . 3^2 = 9

Then perform multiplication and division, left to right. Here, division is first, then multiplication.

  5 +9 +8*2 . . . . . divide 40/8 = 5

  5 +9 +16 . . . . . . multiply 8*2 = 16

Finally, perform addition and subtraction, left to right.

  14 +16 . . . . add 5+9

  30 . . . . . . . add 14+16

In ABC, the measure of the largest angle is 16 less than 4 times the smallest angle. The measure of the middle angle is 7 more than half the measure of the largest angle. What is the measure of the middle angle?

Answers

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°

Answers

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.

The institution can purchase food A for $0.12 per ounce and food B for $0.08 per ounce. How many ounces of each food should a serving contain to meet the dietary requirements at the least cost

Answers

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

The radius of a cylindrical construction pipe is 1.5 ft. If the pipe is 15 ft long whats the volume

Answers

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

Question:-

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

Answer:-

Given:-

[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.

To Find:-

Volume of a cylindrical construction pipe.

Solution:-

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.

The volume of a cylindrical construction pipe is 105.975 cubic ft. [Answer]

1. Anvi borrowed $5,000 from a bank at a flat interest rate of 11% per year for a 3-year
period. How much interest does she have to pay the bank at the end of 3 years? (2dp)

Answers

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.

Researchers studied 208 infants whose brains were temporarily deprived of oxygen due to complications at birth. When researchers detected oxygen deprivation, they randomly assigned babies to either usual care or to a whole-body cooling group.

Note - any given term on the right may be used more than once or not at all.

Answers

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.

Step-by-step explanation:

Past surveys reveal the 30% of tourists going to Las Vegas to gamble spend more than $1,000. The Visitor's Bureau of Las Vegas wants to update this percentage. The new study is to use the 90% confidence level. The estimate is to be within 1% of the population proportion. What is the necessary sample size?

Answers

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.
