h(x) is wider than f(x) and translated 1 unit up.
g(x) is narrower than f(x) and translated 3 units down.
What is translation?It is the movement of the shape in the left, right, up, and down directions.
The translated shape will have the same shape and shape.
There is a positive value when translated to the right and up.
There is a negative value when translated to the left and down.
We have,
a)
f(x) = x²
h(x) = 3x² + 1
This means,
f(x) is dilated with a scale factor of 3 and translated one unit up.
So,
h(x) will be wider than f(x).
b)
f(x) = x²
g(x) = (1/2)x² - 3
This means,
f(x) is dilated with a scale factor of 1/2 and translated to 3 units down.
So,
g(x) will be narrower than f(x).
Thus,

4 cards are drawn from a deck of shuffled cards without
replacement.
Find the probability that:
a) All are kings
b) All are red cards
Answers
a) The probability of drawing all kings from a shuffled deck of cards without replacement is approximately 0.0000014, or 1.4 in 1 million.
b) The probability of drawing all red cards from a shuffled deck without replacement is approximately 0.000000103, or 1.03 in 10 million.
a) Probability of drawing all kings:
To calculate the probability of drawing all kings, we need to determine the total number of possible outcomes and the number of favorable outcomes. Let's break it down step by step:
Step 1: Total number of possible outcomes
In a standard deck of 52 playing cards, there are four kings. When we draw one card, there are 52 cards to choose from. For the second draw, only 51 cards remain, and so on. Therefore, the total number of possible outcomes for drawing four cards without replacement is:
52 × 51 × 50 × 49 = 649,740
Step 2: Number of favorable outcomes
Since we want all four cards to be kings, there are only four kings in the deck. When we draw the first card, there is a 4/52 chance of it being a king. For the second card, the probability reduces to 3/51 since there are three kings remaining out of 51 cards. Similarly, for the third and fourth cards, the probabilities become 2/50 and 1/49, respectively. Therefore, the number of favorable outcomes is:
(4/52) × (3/51) × (2/50) × (1/49) = 1/270,725
Step 3: Calculating the probability
Finally, we can calculate the probability of drawing all kings by dividing the number of favorable outcomes by the total number of possible outcomes:
P(all kings) = (1/270,725) / (649,740) ≈ 0.0000014
b) Probability of drawing all red cards:
Similarly, let's calculate the probability of drawing all red cards from the deck. We follow the same steps:
Step 1: Total number of possible outcomes
When we draw the first card, there are 26 red cards in a deck of 52. For the second draw, there are 25 red cards remaining out of 51, and so on. Hence, the total number of possible outcomes for drawing four cards without replacement is:
26 × 25 × 24 × 23 = 358,800
Step 2: Number of favorable outcomes
Since we want all four cards to be red, there are 26 red cards in the deck. The probability of drawing a red card for the first draw is 26/52. For the second draw, the probability becomes 25/51, for the third draw it is 24/50, and for the fourth draw, it is 23/49. Thus, the number of favorable outcomes is:
(26/52) × (25/51) × (24/50) × (23/49) ≈ 0.037
Step 3: Calculating the probability
The probability of drawing all red cards is the ratio of the number of favorable outcomes to the total number of possible outcomes:
P(all red cards) = (0.037) / (358,800) ≈ 0.000000103

Answers
That day the number of adults was 95 and the number of children was 38
How many children and how many adults swam at the public pool that day?Let's define the variables:
x = number of adults.
y = number of children.
We know that 133 people used the public swimming pool. then we can write:
x + y = 133
We also know that the receipts for admission totaled 270.75, then we can write other equation as:
2.25x + 1.5y = 270.75
Then the system of equations is:
x + y = 133
2.25x + 1.5y = 270.75
In the first equation we can isolate x to get:
y = 133 - x
Now replace that in the other equation to get:
2.25x + 1.5*(133 - x) = 270.75
0.75x + 199.5 = 270.75
0.75x = 270.75 - 199.5
x = 71.25/0.75 = 95
Then the value of y is:
y = 133 - 95 = 38

x - y = 14x - 2y = 3x = 25Step-by-step explanation:
Given the difference of x and y is 14, and the difference of x and 2y is 3, you want two equations, their graph, and the value of x.
EquationsThe difference of 'a' and 'b' is (a -b). Here, the two differences are expressed as the equations ...
x - y = 14x - 2y = 3GraphThe attachment shows a graph of these equations. Their point of intersection is (25, 11), meaning the value of x is 25.
The graph of the first equation is easily drawn by recognizing the x- and y-intercepts are 14 and -14, respectively.
The graph of the second equation will go through the x-intercept point of (3, 0) and the y-intercept point of (0, -3/2). It is probably easier to graph this by hand by considering the x-intercept point and the slope of 1/2.
Algebraic solutionSince we're only interested in the value of x, it is convenient to eliminate the variable y. We can to that by subtracting the second equation from twice the first:
2(x -y) -(x -2y) = 2(14) -(3)

Answers
Answer:
x = days he reads for 4.5 hours = 1 day
y = days he reads for 3.5 hours = 6 days
Step-by-step explanation:
Let
x = days he reads for 4.5 hours
y = days he reads for 3.5 hours
x + y = 7 (1)
4.5x + 3.5y = 25.5 (2)
From (1)
x = 7 - y
Substitute x = 7 - y into (2)
4.5x + 3.5y = 25.5 (2)
4.5(7 - y) + 3.5y = 25.5
31.5 - 4.5y + 3.5y = 25.5
- 4.5y + 3.5y = 25.5 - 31.5
-y = -6
y = 6
Substitute y = 6 into (1)
x + y = 7 (1)
x + 6 = 7
x = 7 - 6
x = 1
x = days he reads for 4.5 hours = 1 day
y = days he reads for 3.5 hours = 6 days

Answers
Besides being simple for its own sake, what other advantage do simple models usually have?
a) Higher accuracy
b) Greater complexity
c) Easier interpretation
d) More detailed predictions
Answers
The correct option is c) Easier interpretation. One of the main advantages of simple models is their ease of interpretation. Simple models tend to have fewer parameters and less complex mathematical equations, making it easier to understand and interpret how the model is making predictions.
This interpretability can be valuable in various domains, such as medicine, finance, or legal systems, where it is important to have transparent and understandable decision-making processes.
Complex models, on the other hand, often involve intricate relationships and numerous parameters, which can make it challenging to comprehend the underlying reasoning behind their predictions. While complex models can sometimes offer higher accuracy or make more detailed predictions, they often sacrifice interpretability in the process.

A rectangle has length 1. 5 times the width, and perimeter 12 cm. What are the dimensions of
the rectangle?
Answers
Answer:
Length = 3.6
Width= 2.4
Step-by-step explanation:
A rectangle has length 1. 5 times the width, and perimeter 12 cm. What are the dimensions of
the rectangle?
So a rectangle has 2 longer sides and 2 shorter sides.
Knowing the length is 1.5 times the width
and perimeter of 12 centimeters.
The Perimeter is the adding of all the values around a shape. A rectangle has 4 sides so you add up all the sides.
1.5w+1.5w+w+w=12
5w=12
12/5=w
w=2.4
To figure the length just multiply 1.5*2.4=3.6
And That is how you solve it :)
