If angle C is 70°, angle B2 is 60° Then angle D will be 50°. So it’s a Scalene triangle.

The time required to increase the size of a cell population by 16% can be determined using the exponential growth model, P(t) = Po * (ln(2) * t). The answer is 0.2141 (rounded to four decimal places).

Given that P = 22, we need to solve for t in the equation 22 = Po * (ln(2) * t) * 1.16.

To explain the steps in more detail, we start with the exponential growth formula P(t) = Po * (ln(2) * t), where P(t) is the size of the population at time t, Po is the initial size of the population, and ln(2) is the natural logarithm of 2.

In this case, we are given that P = 22, which represents the final size of the population. We want to find the time required to increase the size of the population by 16%, so we can set up the equation 22 = Po * (ln(2) * t) * 1.16.

Simplifying the equation, we have 22 = Po * 1.16 * ln(2) * t. Dividing both sides of the equation by Po * 1.16 * ln(2), we get t = 22 / (Po * 1.16 * ln(2)).

Since the initial size of the population (Po) is not given in the problem, we cannot calculate the exact value of t. However, we can determine that t is approximately 0.2141 by substituting Po = 1 into the equation and rounding the answer to four decimal places.

Therefore, the time required to increase the size of the population by 16% is approximately 0.2141 (rounded to four decimal places).

The probability that X is between 22 and 52 is approximately 0.68. To find the probability that X is between 22 and 52, we can use the properties of the normal distribution.

First, we need to standardize the values 22 and 52 using the formula: Z = (X - mean) / standard deviation. For 22: Z1 = (22 - 37) / 15 = -1. For 52:

Z2 = (52 - 37) / 15 = 1. Now, we can refer to the 0.68-0.95-0.997 rule, also known as the empirical rule or the 68-95-99.7 rule. According to this rule: Approximately 68% of the data falls within one standard deviation of the mean.

Approximately 95% of the data falls within two standard deviations of the mean. Approximately 99.7% of the data falls within three standard deviations of the mean. Since the values -1 and 1 fall within one standard deviation of the mean, the probability that X is between 22 and 52 can be estimated as approximately 68%. Therefore, the probability that X is between 22 and 52 is approximately 0.68.

We want to find the height of the dollhouse's front door.

Since the dollhouse's measures is given in inches, we have just two possible right choices:

because the answer should be given in inches.

If the correct option were the third one, 14 in,

then the real door measure would be twice in feet: 28 feet.

If the correct option were the first one, 3 1/2 in,

then the real door measure would be twice in feet: 7 in.

28 feet is a really big door. It is more likely for a house to have a 7 in door.

Answer: B

Step-by-step explanation:

No, the Large counts conditio is not met

The correct option is that, No, the Large Counts Condition is not met.

Conditions for inference are the three conditions on a mean are randomness, whether it is normal distribution and the independence of the test.

Given that,

The reporter selects a random sample of 50 American adults and finds that 28 are unable to name the current vice president.

So the sample is random.

10% condition is also met since the sample size is 50, which must be less than 10% of the total population.

So the 10% condition is also met.

Large counts condition is the condition which requires the sample size to be large enough for the distribution to be approximately normal.

So, the large counts condition is not met.

Hence the correct option is that condition of inference is not met since the Large Counts Condition is not met.

The average temperature change per hour was -2.708 degrees Fahrenheit.

To calculate the average temperature change per hour, we need to find the total temperature change over the 24-hour period and then divide by the number of hours.

The total temperature change is the difference between the starting temperature (41 degrees Fahrenheit) and the ending temperature (-13 degrees Fahrenheit), which is -54 degrees Fahrenheit.

Dividing the total temperature change by the number of hours, we get:

-54 degrees Fahrenheit / 24 hours = -2.25 degrees Fahrenheit per hour.

Rounding to three decimal places, we get an average temperature change per hour of -2.708 degrees Fahrenheit per hour.

Therefore, the length of the box is x+6 = 10 inches, the width of the box is x-2 = 2 inches, and the height of the box is x-1 = 3 inches. Thus, the dimensions of the box are 10 inches by 2 inches by 3 inches.

a) The volume of a rectangular prism is given by multiplying its length, width, and height. Thus, the polynomial that represents the volume of the given box is:

\(V(x) = (x+6)(x-2)(x-1)\)

Expanding this expression, we get:

\(V(x) = x^3 + 3x^2 - 13x - 12\)

Therefore, the polynomial that represents the volume of the box is V(x) = \(x^3 + 3x^2 - 13x - 12.\)

b) We are given that the volume of the box is 60 cubic inches. We can set up an equation by equating the polynomial V(x) to 60 and solving for x:

\(x^3 + 3x^2 - 13x - 12 = 60\)

Simplifying this equation, we get:

\(x^3 + 3x^2 - 13x - 72 = 0\)

We can use either long division or synthetic division to find the roots of this equation. Using synthetic division, we can divide by x-4 and get:

4 | 1 3 -13 -72

|___4 28 60

1 7 15 0

Therefore, the roots of the equation are x = -5, x = -1, and x = 4. However, we can discard the negative roots since they don't make sense in the context of the problem.

Therefore, the length of the box is x+6 = 10 inches, the width of the box is x-2 = 2 inches, and the height of the box is x-1 = 3 inches. Thus, the dimensions of the box are 10 inches by 2 inches by 3 inches.

Answer:

117 cm²

Step-by-step explanation:

area of rectangle = 13 * 7 = 91cm²

area of upper one right angle triangle= 1/2 * 6.5 * 4 =13 cm²

area of both triangles = 13 cm² * 2 = 26 cm²

Total area = 91cm² + 26 cm²

--> 117 cm²

The area of the rectangle is 47.45 square meters and the perimeter is 27.6 meters.

To find the area of the rectangle, you need to multiply the length by the width. So,

Area = length x width
Area = 6.5 M x 7.3 M
Area = 47.45 square meters

To find the perimeter of the rectangle, you need to add up the lengths of all four sides. So,

A triangle sums up to 180 degrees so:

The correct answer is: D. The graph of g(x) is the graph of f(x) shifted to the right 6 units.

In the given function g(x) = f(z - 6), the input variable "z" is being shifted to the right by 6 units. This means that any x-value in the original function f(x) will be replaced with (x - 6) in the function g(x).

Since f(x) is a constant function with a value of 10%, the graph of f(x) is a horizontal line at y = 10%. When we shift the input variable "x" to the right by 6 units in g(x), the horizontal line representing the function f(x) will also shift to the right by the same amount.

Therefore, the correct statement is that the graph of g(x) is the graph of f(x) shifted to the right 6 units.

The volume of one fish food cubes is: 1/64 ft³

Using the volume formula, the volume of the shipping box is: 15/4 × 3 × 13/4 = 585/16 ft³

The number of fish food cubes that can be packed in the shipping box is: 2,340 fish food cubes.

The volume of a box = length × width × height

A cube has equal side lengths, therefore, the volume of a cube = (side length)³ = side length × side length × side length.

We are given that the fish food cubes have side lengths of 1/4 ft. Therefore:

Volume of fish food cubes = 1/4 × 1/4 × 1/4

Volume of fish food cubes = (1 × 1 × 1)/(4 × 4 × 4)

Volume of fish food cubes = 1/64 ft³

Using the volume formula, we are given the parameters of the box as:

Length (l) = 3¾ = 15/4 ft

Width (w) = 3 ft

Height (h) = 3¼ = 13/4 ft

Therefore,

Volume of shipping box = 15/4 × 3 × 13/4

Volume of shipping box = (15 × 3 × 13)/(4 × 4) = 585/16 ft³

The number of fish food cubes that can be packed in the shipping box = volume of shipping box/volume of one fish food cube

= 585/16 ÷ 1/64

= 585/16 × 64/1

= (585 × 64)/(16 × 1)

= 37,440/16

Given that we define f(n) for positive integers n as follows:

f(1) = 2f(n) = 1+ f(n-1) + n² for all n ≤ 2

We are to determine the expression below that is the kth step of unrolling f(n).

To obtain the expression, we will use the recursive definition of f(n):

f(n) = 1 + f(n - 1) + n²

Since the question is asking for the kth step of unrolling f(n),

let's first define a new function f_k(n) which represents the value of f(n) after k unrollings.

Then:f_0(n) = f(n)f_1(n) = 1 + f_0(n - 1) + (n - 1)² = f(n - 1) + n²f_2(n) = 1 + f_1(n - 1) + (n - 2)² = f(n - 2) + (n - 1)² + n²f_3(n) = 1 + f_2(n - 1) + (n - 3)² = f(n - 3) + (n - 2)² + (n - 1)² + n². . .f_k(n) = f(n - k) + (n - k + 1)² + (n - k + 2)² + ... + n²
