Simplify: 22-(8-2) + [6 (205) - 11]​

Answer:

2

Step-by-step explanation:

log_4 (16) is a tiny math problem. It is asking 4^? = 16

See, a log is an exponent. So what power of 4 makes 16? Well, 4^2 = 16. So that means that the log_4(16) = 2

The function y=540(1.04)^x represents exponential growth. The rate of increase can be determined by finding the value of 1.04^x.

For example, if x=1, then the value of 1.04^1 is 1.04, which represents a 4% increase. If x=2, then the value of 1.04^2 is 1.0816, which represents an 8.16% increase. If x=3, then the value of 1.04^3 is 1.1265, which represents a 12.65% increase.

In general, as the value of x increases, the value of 1.04^x increases at a faster rate, resulting in an exponential growth curve. The percentage rate of increase is determined by the value of 1.04. In this case, the percentage rate of increase is 4% per unit increase in x.

On average, it is going to take DJ 7.27 hours to get to the beach.

Average refers to the quotient when a numerator is divided by a denominator.

In this situation, the average refers to the time, which is the quotient of the distance and speed.

The total distance going to the beach from his family = 800 km

The average speed = 110 km/hr

The time to cover the distance of 800 km at 110 km/hr = 7.27 hours (800/110).

Thus, DJ will take 7.27 hours to cover 800 km at 110 km/hr.

If the parlor sold 389389 tattoos and 4343 were arm tattoos, then the probability of next customer does not get an arm tattoos is 0.99

Total number of tattoos sold in this month = 389389 tattoos

Number of arm tattoos = 4343

Number of other tattoos = 389389 - 4343

= 385046

The probability = Number of favorable outcomes / Total number of outcomes

Substitute the values in the equation

The probability of next customer does not get an arm tattoos = 385046 / 389389

Divide the terms

= 0.99

Therefore, the probability of next customer does not get an arm tattoos is 0.99

Therefore ,A pink gold bracelet weight 60 g has 45.6g of gold .

A fraction of 100 is a percentage, also known as percent. Percentage, which is defined as "per 100," represents a fraction of a total sum. 45 out of 100 is what is meant by 45%, for instance. The share of a whole expressed in terms of 100 is discovered when a percentage is calculated. Calculators online or on paper can be used to determine it.

In addition to "out of 100" and "for every 100," the word "percentage" can also be used. You could, for instance, say "it snowed 20% of the time" or "it snowed 20 days out of every 100 days."

Here,

We know that,

A pink gold bracelet weight 60 g has 76% gold, 18% copper and 6% aluminum.

Therefore,

In order to calculate the weight of gold

First we obtain its percentage in bracelet

It's percentage given in question is 76%

Thus,

mass of gold will be 76% of 60g which is 0.76 * 60=45.6g

the Pearson product moment correlation measures the linear relationship between two interval- and/or ratio-scaled variables (scale variables) such as those depicted conceptually by scatter diagrams: True.

A measure of the degree and direction of relationship between two variables assessed on at least an interval scale is the Pearson product-moment correlation coefficient, or Pearson's correlation.

If you want to determine whether there is a linear relationship between two quantitative variables, you may use Pearson's correlation. The expectation of a linear relationship between those variables is the sole part of the study hypothesis.

This approach finds the precise amount or degree of correlation between any two variables and tells if there is or is not any correlation between them.

The interest charged for 3 years would be $75 ($500 x 0.05 x 3). The total amount Ariane has to pay back would be $575 ($500 + $75).

Simple interest is calculated based on the principal of a loan or the initial deposit into a savings account. Simple interest doesn't compound, therefore a creditor will only charge interest on the principal sum, and a borrower will never be required to pay interest on interest that has already accrued.

To calculate simple interest, multiply the principal sum by the time period, interest rate, and time period. Simple interest is calculated as follows: "Simple Interest = Principal x Interest Rate x Time." This equation provides the simplest method for calculating interest.

The fracion 12k⁸/4(k⁵)² expressed in its simplest form is the expression 3/k².

To simplify fraction, we need to factorise the denominator and numerator, and then look for common factors in the numerator and denominator and cancel.

Given the fraction;

12k⁸/4(k⁵)² = 3 × 4 × k⁸/k² × 4 × k⁸ {expressed to get a common factor}

12k⁸/4(k⁵)² = 3 × 4k⁸/k² × 4k⁸

4k⁸ is a common factor to the numerator and denominator, so we cancel it out

12k⁸/4(k⁵)² = 3/k²

Therefore, the simplest form of the fracion 12k⁸/4(k⁵)² is derived as the expression 3/k.

Answer:

It is letter D; No, the ratio between AD and DE is 3:1.

Step-by-step explanation:

The equation of the line that passes through the points (2, 15) and (5, 21) is y = 2x + 11

The coordinates of the first point = (2, 15)

The coordinates of the second point = (5, 21)

The slope of the line = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]

Substitute the values in the equation

The slope of the line = (21-15) / (5-2)

= 6 / 3

= 2

The slope intercept form is

y = mx + b

Substitute the values

15 = 2(2) + b

15 = 4 + b

b = 15 - 4

b = 11

Substitute the values in the equation

Displacement is defined as a change in an object's position. An object's displacement is defined as how far it has moved from its starting point. The dependent variable in the displacement time graph is displacement, which is represented on the y-axis, and the independent variable is time, which is represented on the x-axis. Position-time graphs are another name for displacement time graphs.

The displacement curve is given for 0 ≤ t ≤ 18.

We need to find the total distance of the curve, it will be the positive sum of all displacements.

So, total distance = (7-0) + (3-0) + (2+3) + (2+4) + (7-4)
