Required equation of points plotted on graph relating range gain(k) and charging time(t) is k=4t.

A two-variable linear equation is one in which both variables have exponent 1.

An object in geometry known as a line is simply one that is described as being straight, thin, one-dimensional, zero width, and extending on both sides to infinity.

In essence, a straight line is just a line devoid of any bends.

Additionally, we can state that any line that crosses two certain points on the same plane will be singular.

Answer:

47.5%

Step-by-step explanation:

Given that μ = 144, σ = 27:

For x = 144: z= 144-144/27=0

For x = 198: = 198-144/27 = 2

Therefore, From the normal distribution table: gives  0.5000 and 2 gives .97725

So the required percentage = 0.97725- 0.5000 = 0.47725= 47.5%

Hence, 47.5% of the population would be between 144 and 198

The study in question is an observational one. No treatments were used in the study because there were none.

b) Since the 200 patients who made up the random sample were divided into groups without regard to their physical health.

When patients are divided into groups at random, it may be discovered that one group's patients are in better health than the other. The results then might become skewed. Therefore, our study's conclusion might be false.

The unit rate of the first employee is $29 an hour and the second is $22 an hour.

What is the rate?

Rates are a special type of ratio that incorporates the dimension of time into the denominator. Familiar examples include measurements of speed (miles per hour) or water flow (gallons per minute). Example #1: If a car travels 24 miles in 2 hours, its average speed is a rate of 24 miles/ 2 hours = 12 miles/hr.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The population has increased by 51.56% from last year to this year.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Number of population last year = 2,639,000,000

Number of population this year = 3,999,635,444

The best estimate of the total population of last year and this year.

= [ (3,999,635,444 - 2,639,000,000) / 2,639,000,000 ] x 100

= ( 1360635444 / 2,639,000,000 ) x 100

Answer: Dimension of pool are length = 12 feet, width = 54 feet and depth = 6 feet.

1)  An expression for the amount of fabric needed to make 13 pairs of wings is; 3/4 * $8 = $6 each

2) An expression of the total cost is; 3/4 * $8 * 13 = $78

3) The way we will use  associative and commutative properties is to start by treating 1 yard of fabric like the fraction 4/4.

4) Simplifying equals $78

We are told that each pair of wings is made with 3/4 yard of fabric. Since the fabric costs $8 per yard. Thus;

1) 3/4 * $8 will give us the cost of the amount required for 3/4 yard of fabric.  3/4 * $8 = $6 each

2) Now, we are told that Mr. Townsend needs to make 13 pairs of butterfly wings and as such;

Amount needed to make 13 pairs is expressed as; 3/4 * $8 * 13 = $78

3) Treat 1 yard of fabric like the fraction 4/4.

Now, if this 1 fabric is equal to $8, then it means that 3/4 of the fabric will be $6. That is for one pair of butterfly wings, there's 13 of those so multiply $6 by 13.

This pattern is easier  because we know how much 1 fabric costs, but we don't know what 3/4 of it does, so we treat 1 yard of fabric as the fraction 4/4.

4) Simplifying the expression gives; $78

The side CA has a length of  [tex]\sqrt{c^{2}-b^{2} }[/tex] and Angle C is of 28 degrees.

Given,

Right angled triangle ABC

Length of side AB = b

Length of side BC = c

Angle B = 62°

Angle A = 90°

We have to find the length of side CA and Angle C;

Here,

According to Pythagorean theorem,

Hypotenuse = [tex]\sqrt{base^{2}+altitude^{2} }[/tex]

Here,

Altitude = [tex]\sqrt{Hypotenuse^{2} -Base^{2} }[/tex]

CA = [tex]\sqrt{c^{2} -b^{2} }[/tex]

Now,

Sum of interior angles of a triangle is 180°

Then,

∠A + ∠B + ∠C = 180°

So,

90° + 62° + ∠C = 180°

∠C = 180° - 152°

∠C = 28°
