Twice the difference of a number and 5

Answers

Answer 1
Answer:

Answer:

Step-by-step explanation:

To express "twice the difference of a number and 5" algebraically, we can follow these steps:

Step 1: Let's represent the unknown number as 'x'.

Step 2: The difference of a number and 5 is obtained by subtracting 5 from the number, which gives us 'x - 5'.

Step 3: To find "twice the difference," we multiply the difference by 2, resulting in '2(x - 5)'.

Therefore, "twice the difference of a number and 5" can be expressed algebraically as '2(x - 5)'.

What X !!!!!!!!!!!!!!!!!! Help me please!!!!

Answers

Answer:

x=135°

Step-by-step explanation:

Accordingtotheproblem,

45° + x = 180° [Linearpair]

=> x = 180° - 45°

=> x = 135° (Ans)

Answer:

The value of x is 135°.

Step-by-step explanation:

This figure displays a straight angle, meaning that its measure is 180°.

180° - 45° = 135°

Since angle x is indeed an obtuse angle, the answer is correct! Hope this helps; have a great day.

Camp Elim obtains a $125,000, 6%, five-year loan for a new camp bus on January 1, 2021. If the monthly payment is $2,416.60, by how much will the carrying value decrease when the first payment is made on January 31, 2021?

Answers

Answer:

The loan amount is = $125000

Rate is = 6%

Term of the loan = 5 years or 60 months

EMI is = $2416.60

Now I have solved this using reducing method ans excel sheet. Please find attached the sheet.

So we can see that after 1st payment, the principle is left to $ 123,208.40  

The value decreases by : 125000-123208.40=1791.60

One year consumers spent an average of $23 on a meal at a restaurant. Assume that the amount spent on a restaurant meal is normally distributed and that the standard deviation is $6. Complete parts​ (a) through​ (c) below.a. What is the probability that a randomly selected person spent more than $28?=0.2033
b. What is the probability that a randomly selected person spent between $9 and $21?=0.3608

Answers

The probabilities regarding a person spending are given as follows:

a) More than 28: 0.2033 = 20.33%.

b) Between 9 and 21: 0.3608 = 36.08%.

How to obtain probabilities using the normal distribution?

The z-score of a measure X of a variable that has mean symbolized by \mu and standard deviation symbolized by \sigma is obtained by the rule presented as follows:

Z = (X - \mu)/(\sigma)

  • The z-score represents how many standard deviations the measure X is above or below the mean of the distribution, depending if the obtained z-score is positive or negative.
  • Using the z-score table, the p-value associated with the calculated z-score is found, and it represents the percentile of the measure X in the distribution.

The mean and the standard deviation for this problem are given as follows:

\mu = 23, \sigma = 6

The probability of a person spending more than 28 is one subtracted by the p-value of Z when X = 28, hence:

Z = (28 - 23)/6

Z = 0.83

Z = 0.83 has a p-value of 0.7967.

1 - 0.7967 = 0.2033 = 20.33%.

The probability of spending between 9 and 21 is the p-value of Z when X = 21 subtracted by the p-value of Z when X = 9, hence:

Z = (21 - 23)/6

Z = -0.33

Z = -0.33 has a p-value of 0.3707.

Z = (9 - 23)/6

Z = -2.33

Z = -2.33 has a p-value of 0.0099.

Hence:

0.3707 - 0.0099 = 0.3608 = 36.08%.
