The equation of \($\frac{45}{3}\left[\frac{90}{45}+3\left(19-16\right)\right]\) is 165.

What is PEMDAS rule?

PEMDAS exists as an acronym for the terms parenthesis, exponents, multiplication, division, addition, and subtraction.

How to simplify the equation of \($\frac{45}{3}\left[\frac{90}{45}+3\left(19-16\right)\right]\)?

Given:

\($\frac{45}{3}\left[\frac{90}{45}+3\left(19-16\right)\right]\)

45/3 = 15

Simplifying the given equation, we get

\($\frac{45}{3}\left[\frac{90}{45}+3\left(19-16\right)\right]=15\left[\frac{90}{45}+3(19-16)\right]\)

90 / 45 = 2

By simplifying the above equation, then we get

= 15[2 + 3(19 -16)]

By using the PEMDAS rule

15[2 + 3(19 -16)] = 11

\($\frac{45}{3}\left[\frac{90}{45}+3\left(19-16\right)\right]= 15*11\)

= 165

Therefore, the equation of \($\frac{45}{3}\left[\frac{90}{45}+3\left(19-16\right)\right]\) is 165.

The bus fare in a city is $2.00. People who use the bus have the option of purchasing a monthly coupon book for $27.00. With the coupon book, the fare is reduced to
$1.00. Determine the number of times in a month the bus must be used so that the total monthly cost without the coupon book is the same as the total monthly cost
with the coupon book.

Answers

27 times in a month the bus must be used to make the cost equals with coupon book and without coupon book.

Given,

The bus fare in a city without coupon book = $2.00

The cost of coupon book for a month = $27.00

The reduced fare when using coupon book = $1.00

Now, we have to find the number of times in a month the bus must be used so that the total monthly cost without the coupon book is the same as the total monthly cost with the coupon book.

Number of trips in a month = x

Without coupon:

Total amount = rate × x

Total amount = 2 × x = 2x

With coupon:

Total amount = coupon + rate × x

Total amount = 27 + 1 × x = 27 + x

We have to equate this:

2x = 27 + x

2x - x = 27

x = 27.

That is,

27 times in a month the bus must be used to make the cost equals with coupon book and without coupon book.

How do you solve for x if x/5 = 7/3

Answers

We get that, the value of x is 11.67 when the equation is x / 5 = 7 / 3.

An equation is a combination of two expressions connected by an equal sign.

We are given an equation:

x / 5 = 7 / 3

We need to find the value of x.

Multiply both sides by 5

x / 5  × 5 = 7 / 3 × 5

x = 35 / 3

Now, we will divide 35 by 3 and round off the result to two decimal places:

x = 11.67

Therefore, we get that, the value of x is 11.67 when the equation is x / 5 = 7 / 3.

A quality control expert at LIFE batteries wants to test their new batteries. The design engineer claims they have a variance of 2916 with a mean life of 518 minutes.

If the claim is true, in a sample of 81 batteries, what is the probability that the mean battery life would be less than 526.4 minutes? Round your answer to four decimal places.

Answers

The probability that the mean battery life would be greater than 526.4 minutes if in a sample of 81 batteries having a variance of, 2916 and a mean life of 518 minutes is 0.0808.

What is probability?

The ratio of good outcomes to all possible outcomes of an event is known as probability. A lot of successful results for an experimental with 'n' results can be represented by the symbol x.

Given:

The variance = 2916,

The mean life of a battery, m = 518 min,

The total number of samples, n = 81

Calculate the probability of a mean battery life of lower than 526.4 minutes by the following formula,

z = x - m / (σ / √ n)

Here, x is the expected value, σ is the deviation, and z is the probability.

Substitute the values,

z = 526.4 - 518 / (54 / √81)         [σ = √ variance = √2916  = 54]

z = 1.4

Consult the cumulative standard normal table

P (z < 526.4) = 0.9192,

But we know that

P (z > 526.4) = 1 - P (z < 526.4)

P (z > 526.4) = 1 - 0.9192 = 0.0808

Therefore, The probability that the mean battery life would be greater than 526.4 minutes if in a sample of 81 batteries having a variance of, 2916 and a mean life of 518 minutes is 0.0808.

Enter the correct answer.

Answers

The polynomial -8m²n - 7m²n can be factored using the common factor -m²n. The complete factored form of the polynomial is (-m²n) (8 + 7a).

To find the complete factored form of the polynomial -8m²n - 7m²n, we can factor out common terms from both the terms. The common factor in the terms -8m²n and -7m²n is -m²n. We can write the polynomial as:

-8m²n - 7m²n = (-m²n) (8 + 7a)

Therefore, the complete factored form of the polynomial -8m²n - 7m²n is (-m²n) (8 + 7a). This expression represents the original polynomial in a multiplied form. We can expand this expression using distributive law to verify that it is equivalent to the original polynomial.

Answers

Answer:

Step-by-step explanation:

Since Cindy owns a plot of land measuring 630 yards wide by 987 yards long, to determine what is the area of the land in square yards, square feet, acres and square miles, the following calculations must be performed:

1 yard = 3 feet

1 square yard = 0.000206612 acres

Square yards: 630 x 987 = 621,810 square yards

Square feet: 621,810 x 3 = 1,865,430 square feet

Acres: 621,810 x 0.000206612 = 128.47 acres

The function 4^n + 15n - 1  is divisible by 9 if n is a natural number.

What is the proof of divisibility by 9?

A number is divisible by 9 if the sum of its digits is divisible by 9.

The given number = 4^n + 15n - 1

so we are going to test different natural numbers as n, to check if the resulting number is divisible  by 9.

let n = 1

4^(1) + 15(1) - 1 = 4 + 15 - 1 = 18

sum of 18 = 1 + 8 = 9

9 is divisible by 9

let n = 2

4^(2) + 15(2) - 1 = 16 + 30 - 1 = 45

The Interest rate is 4.05%

And, the number of the year is 10 years

Now placing these values to the above formula;

So, the future value is;

Future value = Present value × (1 + interest rate)^number of years
