Find the G.C.D. of the following:
(a) 30, 45, 75

Answers

Answer 1

Answer:

15

Step-by-step explanation:

We can start by trying to figure out the divisors for each number. A divisor is a whole number that we can multiply by another whole number to equal our target number.

For example, 2's divisors would be 2 and 1, because we can multiply 2 and 1 together to get 2.

30's divisors would be: 1, 30, 2, 15, 3, 10 4, 5, 6

45's divisors would be: 1, 45, 3, 15, 5, 9

75's divisors would be: 1, 75, 3, 25, 5, 15

We should start with 30's divisors because we're searching for a greatest common divisor, so we have to make sure that divisor still fits into the smallest number. Additionally, we should go from biggest to smallest because by eliminating the highest possibilities first, we can ensure that our answer will be the biggest possible one without having to check every single one.

30's biggest divisor is 30, but neither 45 nor 75 have it. 30's next biggest divisor is 15, and that is a common divisor between 45 and 75. Since we worked from the biggest to the smallest, we also know that it is the highest possible common divisor.

That means the G.C.D. of 30, 45, and 75 is 15.

B. 1008 cu. units
C. 196 cu. units
D. 112 cu. units

Answers

Answer:

C) 196 cu. units

Step-by-step explanation:

Volume = lwh/3

             = 7 x 7 x 12 / 3

              =  588/3

              = 196

The volume of a square pyramid is 196 cubic units.

What is the volume?

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

From the given figure, side of square base is 7 units and height is 12 units.

We know that, the volume of square based pyramid =a²h/3.

Now, volume of a pyramid = 1/3 ×7²×12

= 49×4

= 196 cubic units

Therefore, the volume of a square pyramid is 196 cubic units.

The Internal Revenue Service (IRS) provides a toll-free help line for taxpayers to call in and get answers to questions as they prepare their tax returns. In recent years, the IRS has been inundated with taxpayer calls and has redesigned its phone service as well as posting answers to frequently asked questions on its website (The Cincinnati Enquirer, January 7, 2010). According to a report by a taxpayer advocate, callers using the new system can expect to wait on hold for an unreasonably long time of 15 minutes before being able to talk to an IRS employee. Suppose you select a sample of 50 callers after the new phone service has been implemented; the sample results show a mean waiting time of 13 minutes before an IRS employee comes on line. Based upon data from past years, you decide it is reasonable to assume that the standard deviation of waiting times is 11 minutes. Use α=0.05

Required:
a. State the hypotheses.
b. What is the p-value?
c. Using α=0.05, can you conclude that the actual mean waiting time is significantly less than the claim of 15 minutes made by the taxpayer advocate.

Answers

Answer:

a)Null hypothesis : [tex]H_0:\mu \geq 15[/tex]

Alternate hypothesis : [tex]H_a:\mu < 15[/tex]

b)p value = 0.1003

c)We can conclude that the actual mean waiting time is significantly less than the claim of 15 minutes made by the taxpayer advocate.

Step-by-step explanation:

Null hypothesis : [tex]H_0:\mu \geq 15[/tex]

Alternate hypothesis : [tex]H_a:\mu < 15[/tex]

[tex]\mu = 15\\\bar{x}=13\\\sigma = 11\\n = 50[/tex]

Sample size is more than 30 . So, we will use Z test

[tex]Z=\frac{x-\mu}{\frac{\sigma}{\sqrt{n}}}\\Z=\frac{13-15}{\frac{11}{\sqrt{50}}}\\Z=-1.285[/tex]

Use z table to find p value

p value = 0.1003

α=0.05

p value<  α

So, we reject null hypothesis

Hence We can conclude that the actual mean waiting time is significantly less than the claim of 15 minutes made by the taxpayer advocate.

Why do you think y= ax+b is called a linear equation

Answers

Answer:

Y=mx+b Is a linear equasion because if you plot the x and y on a graph it always shows a straight line.

Step-by-step explanation:

For example, y=7x+9,

When x is 1 y is 16, and

when x is 2 y is 23.

When you put those two points on a graph and connect the dots with a ruler, you get a straight line, and you will automatically find that when x is 3 y is 30.

Step-by-step explanation:

Hey there!

Reason:

The power of the term is one.It can be graphed in a at. line on graph.

You can simply define linear equation as the equation which has two variables with 1 exponent.

3. Mrs. Galicia started a savings account for her family and started it with an initial deposit of $1600. The account earns 3.75% interest compounded quarterly.
(a) Write an equation to represent the anount of money in the account as a function of time in years.
(b) How much money will be present in the account in 5 years. *please show plug in step*

Answers

Hey there!

--› Initial deposit: 1600

--› rate = 3.75%

a) First, convert R as a percent to r as a decimal

r = R/100

r = 3.75/100

r = 0.0375 rate per year,

Substitute into formula

= A = P(1 + r/n)nt

A = P(1 + 0.0375/4)^4t

A = 1,600.00(1 + 0.009375)^4t

b)

A = 1,600.00(1 + 0.009375)^4t

A = 1,600.00(1 + 0.009375)^4(5)

A = 1,600.00(1 + 0.009375)^(20)

A = $1,928.28

The amount of money that will be present in the account in 5 years is P(5) = $1923.36

Exponential equations

The standard exponential equations is expressed as:

p(t) = p0(1+r)^t

where:

Po is the initial deposit = $1600Rate "r" =3.75% = 0.0375time "t" = 5 years

Substitute

P(t) =1600(1+ 0.0375)^t
P(t) = 1600 (1.0375)^t

Hence the equation to represent the aount of money in the account as a function of time in years is P(t) = 1600 (1.0375)^t

If t =5 years

P(t) = 1600 (1.0375)^t

P(t) = 1600 (1.0375)^5
P(5) = $1923.36

Hence the amount of money that will be present in the account in 5 years is P(5) = $1923.36

In a closely contested school bond election, polling indicates that 50% of voters are in favor of the bond. Assume central limit theorem conditions apply. Suppose a random sample of 80 voters is selected

Answers

The central limit theorem is used to consider sample sizes of at least 30

The mean of the distribution is 40, and the standard deviation is 4.47

How to determine the mean

The given parameters as:

p =50% --- the proportion

n = 80 --- the sample size

The mean is then calculated as:

[tex]\bar x =np[/tex]

So, we have:

[tex]\bar x =80 * 50\%[/tex]

[tex]\bar x =40[/tex]

How to determine the standard deviation

The standard deviation is calculated as:

[tex]\sigma = \sqrt{np(1 -p)[/tex]

So, we have:

[tex]\sigma = \sqrt{80 *50\% * (1 - 50\%)[/tex]

Evaluate the root

[tex]\sigma = 4.47[/tex]

Hence, the mean of the distribution is 40, and the standard deviation is 4.47

The set of all numbers less than or equal to -1.

Answers

Answer:

anything before -1 is lower than -1.  -1 = -1

Step-by-step explanation:

-10, -9, -8, -7, -6, -5, -4, -3, -2 etc. are in a sense before -1 on a time line and they are all less than -1

Set B represents the set of all the natural numbers less than or equal to -1

[tex]\rm B=\{-\infty ...........-4,-3,-2,-1\}[/tex]

if we include all the numbers the range of set includes every number from

[tex]\rm -\infty \; to -1[/tex] so the set is represented by K

[tex]\rm K = \{ -\infty ,.....-1\}[/tex]

In Mathematics a set is  a collection of objects/elements that are constrained by some particular condition.

Let us consider a situation where "S" is the set and the elements are represented by "x"

A set is always denoted in curly braces. Expression (1) represents the set

[tex]\rm S =[/tex] { [tex]\rm x_1.x_2,x_3, x_4,x_5........x_n[/tex]}...........(1)

Set S  has elements that are represented as [tex]\rm x_1[/tex][tex]\rm\\where \; i \; represents\; the\; index\; of \; the \; element\\n = number\; of \; elements \; in \; the \; set \; x[/tex]

The set of all the natural numbers less than or equal to -1 is the set of all the negative integers including  -1.

So let us say B represents the set of all the natural numbers less than or equal to -1 . Then we can write it as follows

[tex]\rm B=\{-\infty ...........-4,-3,-2,-1\}[/tex]

Set B represents the set of all the natural numbers less than or equal to -1

if we include all the numbers the range of set includes every number from

[tex]\rm -\infty \; to -1[/tex] so the set becomes  

[tex]\rm K = \{ -\infty ,.....-1\}[/tex]
