Ms. Boyd has 9 bills in her purse that consist
of five-dollar bills and twenty-dollar bills. The
value of the bills is worth $105. How many
five-dollars bills and twenty-dollar bills does
Ms. Boyd have?
Answers
Answer:
number of $20 bill = 4
Number of $5 bill = 5
Step-by-step explanation:
Given that:
Total number of $5 and $20 bills = 9
Let :
Number of $5 bills = x
Number of $20 bills = y
Combined worth of all bills = $105
x + y = 9 - - - (1)
5x + 20y = 105 - - - (2)
From (1)
x = 9 - y
Substitute x = 9 - y into (2)
5(9 - y) + 20y = 105
45 - 5y + 20y = 105
15y = 105 - 45
15y = 60
y = 60/15
y = 4
x = 9 - y
x = 9 - 4 = 5
Hence,
number of $20 bill = 4
Number of $5 bill = 5

Answer:
x = 7y = 37Step-by-step explanation:
You want to know the values of x and y that make the angle measures consistent with the triangles being congruent in the given figure.
CongruenceThe side markings show congruent triangles with corresponding vertices (and angles) ...
L (3x+24)° ⇔ P (8x -11)°
M 84° ⇔ Q 84°
N (2x +y)° ⇔ R (no marking)
Corresponding angles L and P have the same measure, so ...
3x +24 = 8x -11
35 = 5x . . . . . . . . add 11-3x
7 = x . . . . . . . . . divide by 5
The measures of these angles are ...
(3(7) +24)° = 45°
Angle sum theoremThe sum of the angles in each triangle is 180°, so the measure of angle N is found to be ...
L +M +N = 180°
45° +84° +N = 180°
N = 51°
This lets us find the value of y from ...
(2x +y)° = 51°
2(7) +y = 51
y = 37 . . . . . . . . subtract 14
The value of x is 7. The value of y is 37.

A landscaper buried a water line around a rectangular lawn to serve as a supply line for a sprinkler system. The length of the lawn is 6 times its width. If 630 feet of pipe was used to do the job, what is the length and the width of the lawn
Answers
Answers:
Length = 270 feet
Width = 45 feet
========================================================
Work Shown:
x = width
6x = length, since it is 6 times the width
P = perimeter of rectangle
P = 2*(Length + Width)
P = 2*(6x + x)
P = 2*(7x)
P = 14x
Plug in the given perimeter P = 630 and solve for x.
P = 14x
14x = P
14x = 630
x = 630/14
x = 45
The width is 45 feet.
The length must be 6x = 6*45 = 270 feet.
The required length and width of the lawn is given as Length = 270 feet and Width = 45 feet.
Given that,
A landscaper buried a water line around a rectangular lawn to serve as a supply line for a sprinkler system. The length of the lawn is 6 times its width. If 630 feet of pipe was used to do the job, what is the length and the width of the lawn is to be determined.
Perimeter is the measure of the figure on its circumference.
Here,
let the length be l and the width be w,
According to the question,
l = 6w
and
Perimeter of the lawn = 630
2 [l + w] = 630
2 [6w + w] = 630
14w = 630
w = 45
Now,
l = 45[6] = 270
Thus, the required length and width of the lawn is given as Length = 270 feet and Width = 45 feet.

For this pair of functions, explain how you can tell if the two functions are inverses?
Answers
The inputs and outputs match up with each other implying that they are inverses of each other.
How to determine if the functions are inverse?To determine if the functions are inverses of each other, you need to check two conditions:
Composition of Functions: If two functions, let's call them f(x) and g(x), are inverses, then when you compose them in either order, you should get the identity function. Domain and Range: The domain of one function should match the range of the other function, and vice versa.According to the previous information we can conclude that the inputs and outputs match up with each other implying that they are inverses of each other.

Answers
The graphs that are not graphs of polynomials are the ones that have a cusp, a break, do not pass the horizontal line test, or are not smooth.
The graph could be that of a polynomial function if it meets the following criteria: it is smooth, continuous, and does not have any cusps or breaks.
Reasons why the other graphs are not polynomial functions:
1. The graph has a cusp: Polynomial functions have smooth curves without any sharp points (cusps).
2. The graph has a break: Polynomial functions are continuous, meaning there should not be any breaks or gaps.
3. The graph does not pass the horizontal line test: This is not a criterion for polynomial functions. The horizontal line test checks if a function is one-to-one, which is unrelated to polynomial functions.
4. The graph is not smooth: Polynomial functions have smooth, continuous curves.
Based on these criteria, only the graph that is smooth and continuous without any cusps or breaks could be the graph of a polynomial function.

Answers
The range of the random variable d is {-4, -2, 0, 2, 4}, so the correct answer is option b.
To find the range of the random variable d, we need to consider all possible outcomes of the experiment and calculate the value of d for each outcome.
In this experiment, a fair coin is flipped 4 times. Each flip can result in either a "heads" or "tails" outcome.
Let's consider the possible outcomes and calculate the corresponding values of d:
1. Four heads (HHHH): d = 4 - 0 = 4
2. Three heads and one tail (HHHT, HHTH, HTHH, THHH): d = 3 - 1 = 2
3. Two heads and two tails (HHTT, HTHH, THHH, TTHH, HTTH, HHTH): d = 2 - 2 = 0
4. Three tails and one head (TTTH, TTHT, THTT, HTTT): d = 1 - 3 = -2
5. Four tails (TTTT): d = 0 - 4 = -4
The range of d is the set of all possible values that d can take on, which is {-4, -2, 0, 2, 4}.

The __________forecasting model uses nonlinear optimization to forecast the adoption of innovative and new technologies in the marketplace.

The Bass diffusion model is a forecasting model that uses nonlinear optimization to predict the adoption of innovative and new technologies in the marketplace.
It was developed by Frank Bass in 1969 and has since become a widely used method for predicting the spread of new products in the market.
The Bass model assumes that the adoption of a new technology is driven by two factors: the innovative individuals who are the first to adopt, and the imitative individuals who adopt based on the influence of others. The model uses a combination of these two factors to predict the rate of adoption over time.
The Bass model takes into account the potential market size, the rate of innovation, and the rate of imitation. It is based on the assumption that the number of potential adopters is finite and that the rate of adoption will slow down as the market becomes saturated. The model also assumes that the rate of innovation will decrease over time as the technology becomes more established in the market.

What is the perimeter of 6(1/2x + 5)
Answers
Answer: The perimeter of a rectangle is the sum of the lengths of all four sides. If one of the sides is 6(1/2x + 5), then we can find the perimeter by multiplying that by 2.
Perimeter = 2*6(1/2x + 5)
Perimeter = 12(1/2x + 5)
To simplify the expression, we can distribute the 12:
Perimeter = 121/2x + 125
Perimeter = 6x + 60
So the perimeter of 6(1/2x + 5) is 6x + 60.

(a) why does the mean accurately summarize a normal distribution? (b) why does the mean inaccurately summarize a skewed distribution?
Answers
The mean accurately summarize a normal distribution because it is the center point. While the mean inaccurately summarize a skewed distribution because the mean is meant to balance the distribution with a tail, it is pulled to a tail and therefore the mean would not be in the center.
The mean is the mathematical average and it is probably the measure of central tendency that is most familiar. One can calculate the mean by adding all the values and dividing it with the total number of observations in a set of data. The normal distribution of mean is observed when the distribution of data near the mean are more frequent in occurrence than data far from the mean, it is also referred as Gaussian distribution. Skewed distribution is not symmetrical nor equal, it is deviated in one or the other side of the graph.
