The problem states that Bert split all his cookies evenly among 4 contestants, so the total number of cookies Bert had can be found by multiplying the number of cookies each contestant received by the number of contestants:

4 * 24 = 96

Therefore, Bert had a total of 96 cookies to start with.

We can also write an equation to represent the problem, where c represents the number of cookies Bert had to start with:

c / 4 = 24

This equation states that the number of cookies Bert had divided by the number of contestants (4) is equal to the number of cookies each contestant received (24).

To solve for c, we can multiply both sides of the equation by 4:

c = 4 * 24

c = 96

So the solution confirms that Bert had 96 cookies to start with.

173 units2 is the area of the figure.

A point where two lines meet produces an angle.

The breadth of the "opening" between these two rays is referred to as a "angle". It is depicted by the figure.

Radians, a unit of circularity or rotation, and degrees are two common units used to describe angles.

By connecting two rays at their ends, one can make an angle in geometry. The sides or limbs of the angle are what are meant by these rays.

The limbs and the vertex are the two main parts of an angle.

The common terminal of the two beams is the shared vertex.

Hence, 173 units2 is the area of the figure.

By using sum of sequence the value of (3+6+9+...+57) is 570, which is option C).

What is sum of the sequence ?

The sum of a sequence is the total result of adding up all the numbers in the sequence. The method for finding the sum of a sequence depends on whether the sequence is arithmetic or geometric.

For an arithmetic sequence, in which each term is obtained by adding a fixed number (called the common difference) to the previous term, the sum of the first n terms can be found using the formula:

[tex]Sn = n/2(2a + (n-1)d)[/tex]

where a is the first term, d is the common difference, and n is the number of terms.

For a geometric sequence, in which each term is obtained by multiplying the previous term by a fixed number (called the common ratio), the sum of the first n terms can be found using the formula:

[tex]Sn = a(1-r^n) / (1-r)[/tex]

where a is the first term, r is the common ratio, and n is the number of terms.


According to the question:
We can notice that each number in the sequence 3, 6, 9, ..., 57 is 3 times the corresponding number in the sequence 1, 2, 3, ..., 19.

So, we can find the sum of the sequence 3, 6, 9, ..., 57 by finding the sum of the sequence 1, 2, 3, ..., 19 and then multiplying by 3.

The sum of the sequence 1, 2, 3, ..., 19 is:

1 + 2 + 3 + ... + 19 = (19/2)(1 + 19)/2 = 190

Multiplying by 3, we get:

3 + 6 + 9 + ... + 57 = 3(1 + 2 + 3 + ... + 19) = 3(190) = 570

Therefore, the value of (3+6+9+...+57) is 570, which is option C).

The probability that the sample mean will be greater than M = 10 pounds is 0.9525.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, with 0 indicating the event is impossible and 1 indicating it is certain. Probability is used in many fields, including mathematics, statistics, science, and finance.

To solve this problem, we need to use the central limit theorem (CLT), which states that the distribution of sample means will be approximately normal, regardless of the shape of the population distribution, as long as the sample size is large enough.

Since the sample size is small (n = 4), we need to use the t-distribution instead of the normal distribution. However, since the population standard deviation is known, we can use the standard normal distribution with a z-score.

First, we need to calculate the standard error of the mean:

SE = σ / sqrt(n) = 6 / sqrt(4) = 3

Next, we can calculate the z-score:

z = (M - µ) / SE = (10 - 15) / 3 = -1.67

Finally, we can use a standard normal distribution table or calculator to find the probability of a z-score greater than -1.67:

p(M > 10) = P(z > -1.67) = 0.9525 (rounded to four decimals)

Therefore, the probability that the sample mean will be greater than M = 10 pounds is 0.9525.

After answering the presented question, we can conclude that As a range result, the class breadth in this frequency distribution table is one.

The variable's range is calculated by taking its maximum observed value and subtracting its minimum observed value (minimum). Possible range or variational bounds: a variety of steel costs; a variety of styles; The scope or magnitude of a method or action: perception. The maximum or anticipated range of a weapon's projectile. A list or set's range is the number between the lowest and maximum. Align all of the numbers before identifying the region. Next, subtract (reduce) the lowest number from the highest number. The solution includes the range of the list. The solution specifies the range of the list.

To calculate the class width, we must first determine the range of values within each class interval.

The class intervals are as follows:

[tex]0-1\s2-3\s4-5\s6-7[/tex]

8-9

0-1 interval range: 1-0 = 1

2-3 interval range: 3-2 = 1

5-4 = 1 interval range of 4-5

7-6 = 1 interval range of 6-7

8-9 interval range: 9-8 = 1

The intervals all have the same range of one.

To calculate the class width, subtract the upper limit of the first interval from the lower limit of the first interval.

Higher limit of first interval - Lower limit of first interval = class width

What is logarithms?

Logarithms are mathematical functions that are used to solve equations involving exponents. Specifically, a logarithm is the inverse operation of exponentiation. Just as exponentiation involves raising a base to a power, logarithms involve finding the power to which a base must be raised to produce a given value.

The logarithm of a number y with respect to a base b is written as logb y, and it is defined as the exponent to which the base b must be raised to produce the number y. In other words, if [tex]b^x = y[/tex], then logb y = x.

According to the question:
In Exercise 36(a), we found that the value of a dollar decreases by 26% over 5 years. We can use this information to answer the following questions:

(a) To estimate the cost of the same house in 10 years, we need to solve the equation:

0.74t = 105,000

where t is the time in years. Solving for t, we get:

[tex]t = log(105,000) / log(0.74) = 17.9[/tex]

So it will take approximately 17.9 years for the value of the dollar to decrease by 26% enough to make the $105,000 house cost the same as it does today. Therefore, we can estimate the cost of the same house in 10 years to be:

[tex]$105,000 * (1 / 0.74)^(10/17.9) = $211,775.22[/tex]

(b) To estimate the cost of a $50 textbook in 8 years, we need to find the value of k in the exponential function:

[tex]V(t) = V(0) * e^kt[/tex]

where V(0) is the initial value (in this case, $50), t is the time in years, and V(t) is the value after t years. We know that the value of a dollar decreases by 26% over 5 years, so we can use this information to find k:

[tex]0.74 = e^(k*5)[/tex]

Taking the natural logarithm of both sides, we get:

ln(0.74) = 5k

Solving for k, we get:

k ≈ -0.064

So the exponential function for the value of a dollar over time is:

[tex]V(t) = $50 * e^{-0.064t}[/tex]

To estimate the cost of the textbook in 8 years, we can plug in t = 8 into this function and solve:

[tex]V(8) = $50 * e^{-0.064*8} = $32.78[/tex]

Therefore, we can estimate the cost of a $50 textbook in 8 years to be approximately $32.78.

The domain is : (-∝ , ∝) and

The range is : [0,∝), {yIy ≥ 0}

Part B:

The transformation which occurs from f(x) to h(x) is a vertical shift up to 2 units.

Expressions separated by an equal sign are functions. Both dependent and independent variables are present.

Given Part A:

given the function is g(x) = I x - 7 I

hence from the function, vertex = (h,k)

h = 7 and k = 0

(h,k) = (7,0)

Find the domain by finding where the function is defined.

therefore, domain =  (-∝ , ∝) , where {xIx ∈ R}

The range is the set of values that corresponds with the domain.

therefore, range =  [0,∝), {yIy ≥ 0}

Part B:

given the parent function is:  f(x) = |x|

which is transformed to h(x) = |x| + 2

To find the transformation, compare the function to the parent function and check to see if there is a horizontal or vertical shift, reflection about the x axis or y axis, and if there is a vertical stretch.

Parent function = f(x) = |x|

Horizontal shift = none

Vertical shift = up 2 units.

Reflection about the x axis = none

hence from the function we can determine the vertex (h,k)

= (0,2)

Find the domain by finding where the function is defined.

therefore, domain =  (-∝ , ∝) , where {xIx ∈ R}

The range is the set of values that corresponds with the domain.

The coordinate system is divided into four quadrants, numbered from I to IV, which are separated by the x- and y-axes. The origin is located at the intersection of the x- and y-axes, and has coordinates (0, 0)

The ΔSTU lies in Q3 if it reflected then ΔS'T'U' lies in Q4, it means that the point is located in the fourth quadrant of the Cartesian coordinate system. In this quadrant, the x-coordinates are positive and the y-coordinates are negative.

More specifically, if we assume that the point ΔS'T'U' is represented by the coordinates (x, y), then we have:

x > 0 (because it lies to the right of the y-axis)

y < 0 (because it lies below the x-axis)

The recursive relationship that describes how the number of Marco's followers is changing each day is Pt = Pt-1 + 32.

It should be noted that after 5 days, Marco will have 597 followers.

The relationship is Pt = Pt-1 + 32 where Pt is the number of followers on day t and Pt-1 is the number of followers on the previous day.

In this case, to calculate how many followers Marco will have after 5 days, we can use this recursive relationship starting with P0 = 437 (the initial number of followers):

P1 = P0 + 32 = 437 + 32 = 469

P2 = P1 + 32 = 469 + 32 = 501

P3 = P2 + 32 = 501 + 32 = 533

P4 = P3 + 32 = 533 + 32 = 565

To find the length and width of each room on the blueprint, we need to use the given scale of 1 in. : 4 ft. This means that every 1 inch on the blueprint represents 4 feet in the actual house.

To find the length and width of each room on the blueprint, we can multiply the actual length and width of each room by 1/4 (or divide by 4). This gives us:

Living room: Length = 12 ft. ÷ 4 = 3 in., Width = 8 ft. ÷ 4 = 2 in.

Kitchen: Length = 16 ft. ÷ 4 = 4 in., Width = 16 ft. ÷ 4 = 4 in.

Office: Length = 16 ft. ÷ 4 = 4 in., Width = 8 ft. ÷ 4 = 2 in.

Bedroom: Length = 20 ft. ÷ 4 = 5 in., Width = 20 ft. ÷ 4 = 5 in.

Bedroom: Length = 10 ft. ÷ 4 = 2.5 in., Width = 20 ft. ÷ 4 = 5 in.

Bathroom: Length = 16 ft. ÷ 4 = 4 in., Width = 8 ft. ÷ 4 = 2 in.

Therefore, the length and width of each room on the blueprint are:

Living room: 3 in. x 2 in.

Kitchen: 4 in. x 4 in.

Office: 4 in. x 2 in.

Bedroom: 5 in. x 5 in.
