The step that indicates the addition property of equality while solving the equation -1 - 6x = x - 15 is : (b) -1 - 6x + 15 = x - 15 + 15.

The "addition-property" of equality states that if we add the same quantity to both sides of an equation, the equation remains true.

In the equation -1 - 6x = x - 15, we need to isolate the variable term 'x'.

To isolate variable "x",  we are adding 15 to both sides of the equation, which is the addition property of equality. This step simplifies the equation and isolate the variable "x" on one side.

So, we get,  -1 - 6x + 15 = x - 15 + 15,

Therefore, the correct step indicating the "addition-property" is (b).

As our determined t-score (2.77) is larger than the critical t-value (2.262), we disregard the null hypothesis in favor of the alternative one

Given data:

The 1980 mean weight (μ) was 180.4 pounds, while the 2023 sample mean weight (x) was 197.9 pounds;

additionally, the sample size (n) was 10 and the sample standard deviation (σ) was 20 pounds.

At a significance level of 0.05, we calculate the t-score by first dividing (x-μ)/(σ/sqrt(n)).

This gives us the value 17.5/6.32 or 2.77 for the t-score.

Afterward, it is necessary to find the critical t-value with a two-tailed test at a significance level α=0.05 in respect to having 9 degrees of freedom (df = n – 1 = 10 – 1 = 9).

This can be located through either a t-distribution table or an online calculator; the result displays the calculated critical t-value being approximately ±2.262.

As our determined t-score (2.77) is larger than the critical t-value (2.262), we disregard the null hypothesis in favor of the alternative one, signifying there is a glaringly significant disparity between the average mass of grown male adults from 1980 and 2023 which upholds the researcher's statement that since 1980, males in the U.S. have gotten heavier.

The volume of the composite figure is calculated as:

= 1,894.2 cm³

The volume of the composite figure can be calculated using:

Volume = volume of rectangular prism + 1/2(volume of cylinder)

Volume of rectangular prism = length * width * height

length = 15 cm

width =  2(6) = 12 cm

height = 10 cm

Volume of rectangular prism = 15 * 12 * 10 = 1,800 cm³

Volume of half Cylinder = 1/2(πr²h)

Answer: Maya’s mix will be more lemony.

Step-by-step explanation:

          We see that both Jonathan and Maya mix 7 teaspoons of the powdered lemon mix. Since we are finding whose mix will be more lemony, we need to find the person who added less water since their mixture will be less diluted.

          This leads us to Maya, she only added 1 cup of water while Jonathan added 2 cups of water. Maya's mixture will have a higher concentration since she has a higher ratio of lemon to water than Jonathan.

Since on average, 66% of the days in Seattle, Washington, are cloudy or rainy, a model that could be used to simulate this situation is an experimental probability model of about 2/3.

In this scenario and exercise, you are to required to describe a model that you could be used to simulate a situation in which 66% of the days in Seattle, Washington, are cloudy or rainy on an average.

In this context, we can reasonably infer and logically deduce that the most accurate and feasible model to use would be an experimental probability model of about 2/3;

66% = 66/100 = 33/50 ≈ 2/3.

In conclusion, you should select two (2) red marbles that each represent cloudy or rainy days and one (1) blue marble that represent non-cloudy or non-rainy days, and then pick one marble randomly. Repeat several times in order to determine experimental probability that a day would either be cloudy or rainy.

The fraction in factored form is determined as  (x - 8)(x + 10) / (x - 10)(x + 8).

The quotient of the division is calculated as follows;

( x² - 3x - 40 )/ (x² + 8x - 20) ÷ (x² + 13x + 40)/(x² + 12x + 20)

Factorize each of the expressions;

x² - 3x - 40

= x² + 5x - 8x - 40

= x(x + 5) - 8(x + 5)

= (x + 5)(x - 8)

x² + 8x - 20

= x² + 2x - 10x - 20

= x(x + 2) - 10(x + 2)

= (x + 2)(x - 10)

x² + 13x + 40

=  x² + 5x + 8x + 40

= x(x + 5) + 8(x + 5)

= (x + 5)(x + 8)

x² + 12x + 20

=  x² + 2x + 10x + 20

= x(x + 2) + 10(x + 2)

The fraction in factored form is written as;

(x + 5)(x - 8)/(x + 2)(x - 10) ÷ (x + 5)(x + 8)/(x + 2)(x + 10)

Answer:

11.72 hours

Step-by-step explanation:

In a continuous exponential growth model, the formula for the size of the population at time t is given by:

N(t) = N₀ * e^(rt)

where N₀ is the initial population size, r is the growth rate parameter, and e is the mathematical constant approximately equal to 2.71828.

To find the time it takes for the population size to double, we can set N(t) equal to 2N₀ and solve for t:

2N₀ = N₀ * e^(rt)

Dividing both sides by N₀:

2 = e^(rt)

Taking the natural logarithm of both sides:

ln(2) = rt * ln(e)

Since ln(e) = 1:

ln(2) = rt

Solving for t:

t = ln(2)/r

Substituting the given growth rate parameter of 5.9% per hour:

t = ln(2)/(0.059) ≈ 11.72 hours

Therefore, it takes approximately 11.72 hours for the size of the population to double.
