A sign says that the price marked in all music instruments equipment is 30% off the original price. You buy a guitar of $315. What is the original price?

Answer:

0.7493 or 74.93%

Step-by-step explanation:

We are given;

Population mean; μ = 100

Population standard deviation; σ = 12

Sample mean 1; x1¯ = 90

Sample mean 2; x2¯ = 120

Z-score formula of the data given is;

z = (x¯ - μ)/σ

z1 = (90 - 100)/12

z1 = -0.83

z2 = (120 - 100)/12

z2 = 1.67

Since we wan to Find the probability that a randomly selected bill is between $90 to $120.

Thus;

P(90 < x¯ < 120) = P(−0.83 < Z < 1.67)

Probability will be gotten from online probability with 2 z-scores calculator to get;

P = 0.7493

Answer:

B

Step-by-step explanation:

The farm needs 90 pigs to be added to the farm to make the ratio 2:3.

The relationship in quantity, amount, or size between two or more things.

Given that, A certain farm raises only chickens and pigs. The ratio

of chickens to pigs on that farm is 5:3. If there are currently 160 animals in total, they need to add some more pigs to make the ratio 2:3.

Let the current number of animals be x,

5x+3x 160

x = 20

Therefore, there are 100 chickens and 60 pigs in the farm.

Let the number of pigs to be added be y,

100/(60+y) = 2/3

150 = 60+y

y = 90

Hence, The farm needs 90 pigs to be added to the farm to make the ratio 2:3.

Answer:

Mean = 12

Step-by-step explanation:

The arithmetic mean of a distribution is the sum of the number of samples in the distribution divided by the number of samples in the dataset. It is a measure of central tendency. The mean is represented as follows:

[tex]\bar x = \frac{\sum x}{n} \\where\\\bar x = mean\\\sum x = sum\ of\ individual\ terms\\n = number\ of\ terms\\\therefore \bar x = \frac{14\ +\ 10\ +\ 17\ +\ 11\ +\ 9\ +\ 15\ +\ 6\ +\ 14}{8}\\\bar x = \frac{96}{8} \\\bar x = 12[/tex]

#SPJ6

Answer: the answer is 16

Step-by-step- explanation:

Since the two sides of a triangle must be greater than the third we can take the sum of two smallest sides and add them together to equal 92. Meaning the length of the longest side MUST BE 91 feet so the amount of the remaining rope would equal to 107-91 and that’s where we get 16

The inequality that represents this scenario is:

[tex]5 + 2.75x \le 21[/tex]

The complete question describes the use of word problems to represent inequalities. The $21 means that there is a limit to the number of stops she can take using the train.

From the complete question, we have the following parameters:

Initial Fee = $5

Rate per stop = $2.75

Amount = $21

The inequality that represents the scenario is calculated using:

Initial Fee + Rate * Number of stops <= Amount

We use <= because the total charges must not exceed the amount.

Let the number of stops be x.

The above formula becomes

[tex]5 + 2.75 * x \le 21[/tex]

[tex]5 + 2.75x \le 21[/tex]

Hence, the inequality that represents this scenario is:

[tex]5 + 2.75x \le 21[/tex]

Step-by-step explanation:

Answer:

1120

Step-by-step explanation:

The ratio Steve : Mandy is 5 : 3.

We use a proportion to find the number of votes Steve received.

x = number of votes Steve received.

5/3 = x/420

3x = 5 * 420

x = 5 * 140

x = 700

Steve received 700 votes.

The total number of votes is the sum of the votes Steve receive and Mandy received.

420 + 700 = 1120
