Answers

Answer:

y = x -2

Step-by-step explanation:

Slope = 1

(-6 , -8)

y - y₁ = m(x - x₁)

y - [-8] = 1(x - [-6] )

y + 8 = x + 6

y = x + 6 - 8

LifeCharge Batteries claims that their batteries last an average of 210 hours when used in a hand held gaming system, with a standard deviation of about 9 hours. An independent quality control company took a sample of 34 batteries, and used the same hand held gaming system that LifeCharge used to record the time the batteries lasted.
1. Assuming the claim is true, what is the probability that the value of the sample mean is greater than 251.7 hours.
2. The sample mean was found to be 251.7, what does this say about the claim?
A. The sample mean is quite far off from the mean claimed, casting doubt on the current mean.
B. The sample mean is sufficiently close to the mean claimed, supporting the current mean.
C. The sample mean found does not truly support nor cast doubt on the current mean.

Answers

Answer:

The answer is "0.0023 and Choice a"

Step-by-step explanation:

In point a:

The central limit theorem:

[tex]\mu_{X}= 250\\\\\sigma_{X}=\frac{\sigma}{\sqrt{n}}=\frac{6}{\sqrt{100}} =0.6\\\\P(\bar{X}>251.7)\\\\=P(z>\frac{251.70-250}{0.6})\\\\=P(z>2.83)\\\\=1-0.9977\\\\=0.0023[/tex]

In point b:

The chance is lower than 0.05. This means that it is very rare to see the average sample above 251.8 if the argument is valid, that is why the means of the sample is far away from the common claimed and casts doubt on the actual mean.

which of the following is a quadrantal angle​

Answers

Question:

Which of the following is a quadrantal angle?

a) π/2        b) π/3        c) 2π/3      D) 4π/5​

Answer:

[tex](a)\ \frac{\pi}{2}[/tex]

Step-by-step explanation:

Required

Which of a to d is a quadrantal angle

An angle is said to be quadrantal if and only if the angle has its terminal side on the x or y axis.

Such angles (in degrees) are: 90, 180, 270, etc.

So, we have:

[tex](a)\ \frac{\pi}{2}[/tex]

[Convert to degrees]

[tex]\frac{\pi}{2} = \frac{180}{2}[/tex]

[tex]\frac{\pi}{2} = 90[/tex]

Hence:

[tex](a)\ \frac{\pi}{2}[/tex] is a quadrantal angle

Answer:

7. [tex]c = 15.81[/tex]

Step-by-step explanation:

Required

Determine the third sides

(7): We have

[tex]b = 5[/tex]

[tex]a = 15[/tex]

[tex]c=??[/tex]

To find c, we make use of Pythagoras theorem

[tex]c^2 = a^2 + b^2[/tex]

[tex]c^2 = 5^2 + 15^2[/tex]

[tex]c^2 = 250[/tex]

[tex]c = \sqrt{250[/tex]

[tex]c = 15.81[/tex]

(8): We have

[tex]c = 20[/tex]

[tex]a = 12[/tex]

[tex]b = ??[/tex]

To find c, we make use of Pythagoras theorem

[tex]c^2 = a^2 + b^2[/tex]

[tex]20^2 = 12^2 + b^2[/tex]

[tex]400 = 144 + b^2[/tex]

[tex]b^2 = 400 - 144[/tex]

[tex]b^2 = 256[/tex]

[tex]b = \sqrt{256[/tex]

15% of customers that come to your
taco truck order two tacos. If 300 guests
come to your store, how many of them
will you expect to order two tacos?

Answers

Answer:

Number of customers (double taco)= 45

Step-by-step explanation:

Giving the following information:

Double taco order rate= 15% = 0.15

Total number of customers= 300

To calculate the number of customers that order two tacos, we need to use the following formula:

Number of customers (double taco)= Double taco order rate*total number of taco

Number of customers (double taco)= 0.15*300

Number of customers (double taco)= 45

If you invest 3,500 in a savings account that pays 4% simple interest how much will the new balance be after including interest?

Answers

Answer:

New balance = 3640

Step-by-step explanation:

Given the following data;

Interest rate = 4% = 4/100 = 0.04

Principal = 3500

To find the new balance;

First of all, we would find the amount at the interest rate;

New amount = interest rate * principal

New amount = 0.04 * 3500

New amount = 140

Now, to find the new balance;

New balance = principal + new amount

New balance = 3500 + 140

New balance = 3640

Raina received a $90 gift card for a coffee store. She used it in buying some coffee that's cost $7.38 per pound. After buying the coffee, she had $53.10 left on her card. How many pounds of coffee did she buy?

Answers

Answer:

5 lbs

Step-by-step explanation:

90 - 53.10 = 36.90

She spent $36.90 on coffee. Since it cost $7.38 per pound, we can divide the total cost by 7.38 to figure out how many pounds she bought:

36.90 / 7.38 = 5

Raina bought 5 pounds of coffee.

Step-by-step explanation:

9x+10y =1 9x-6y=-15 solve using elimination

Answers

Answer:

I. x = -1

II. y = 1

Step-by-step explanation:

Given the following algebraic expressions;

9x + 10y = 1 .......equation 1

9x - 6y = -15 ......equation 2

To solve using the elimination method, we would subtract eqn 1 from eqn 2.

(9x - 9x) + (-6y - 10y) = (-15 - 1)

0x - 16y = -16

-16y = -16

16y = 16

y = 16/16

y = 1

Next, we would find the value of x;

From eqn 1;

9x + 10y = 1

Substituting the value of y, we have;

9x + 10(1) = 1

9x + 10 = 1

9x = 1 - 10

9x = -9

x = -9/9

x = -1

What is an expression?

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

Given that, Club members are charged a one-time membership fee of $32 and pay $4 per class. Non-members pay $8 per class.

Let y represent the number of karate classes attended.

a) The cost for a non-member to attend y classes is

Non-members pay $8 per class.

So, the expression is 8y

b) The cost for a member to attend y classes is

Club members are charged a one-time membership fee of $32 and pay $4 per class.

Now, the expression is 32+4y

c) Set the two expressions equal to each other, that is

8y =32 + 4y

8y-4y=32

4y=32

y=8

Therefore, the expression represents the cost for a non-member to attend y classes is x=8y.

Answers

Answer:

There is a 40% chance that she will choose a can of beef soup, a 20% chance that she will choose a can of chicken soup, and a combined 60% chance that she will choose a can of beef or chicken soup.

Step-by-step explanation:

Since Ms. Vellejo has 1 can of tomato soup, 4 cans of chicken soup, 3 cans of cheese soup and 2 cans of beef soup in her cabinet, and she will randomly choose one can of soup, to determine what is the probililty that she will choose a can of beef or chicken soup, the following calculation must be performed:

1 + 4 + 3 + 2 = 10

Beef soup = 2 cans = 2/10 = 0.2 = 20%

Chicken soup = 4 cans = 4/10 = 0.4 = 40%

20 + 40 = 60

Thus, there is a 40% chance that she will choose a can of beef soup, a 20% chance that she will choose a can of chicken soup, and a combined 60% chance that she will choose a can of beef or chicken soup.

In a closed economy, saving and investment must be equal, but this is not the case in an open economy. In the following problem, you will explore how saving and investment are connected to the international flow of capital and goods in an economy. Before delving into the relationship between these various components of an economy, you will be asked to recall some relationships between aggregate variables that will be useful in your analysis. Recall the components that make up GDP. National income (Y) equals total expenditure on the economy's output of goods and services. Thus, where C = consumption, I = investment, G = government purchases, X = exports, M = imports, and NX = net exports: Y =____. Also, national saving is the income of the nation that is left after paying for____. Therefore, national saving (S) is defined as: S =____. Re-arranging the previous equation and solving for Y yields Y =_____. Plugging this into the original equation showing the various components of GDP results in the following relationship: S =_____. This is equivalent to S =____, since net exports must equal net capital outflow (NCO, also known as net foreign investment). Now suppose that a country is experiencing a trade surplus.
