The statement that is false on Jose drawing cards from the deck is B. For a given number of selections, we can use Joseph's graph to find the number of diamonds that he has picked so far.

What is probability?

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

here, we have,

given that,

Jose draws a card from a deck replaces it and draws again he records a number of times he draws an ace. He decides to record the total number of aces that he selects and calculates the proportion of aces that he has selected so far after each pick. He then constructs a graph to visualize his results.

as the graph can not be used:

Jose only recorded the number of aces he selected, not the number of diamonds. Therefore, we cannot use his graph to find the number of diamonds he picked.

However, if we were to use the graph to find the number of aces that Jose has picked so far, then we would be successful. The other statements are true as Jose recorded the cards he took and the cards were replaced after each pick.

Answers

Answer:

A movie is $2.5

A video game is $6

Step-by-step explanation:

Pre-Solving

We are given that Ann had rented 2 movies and 5 video games for a total of $35.

We also know that she also rented 8 movies and 3 video games for a total of $38.

We want to know how much a movie costs, and how much a video game costs.

If a movie costs x dollars, then a video game costs y dollars.

Solving

This means that costwise, 2 movies will cost 2x, and 5 video games will be 5y.

8 movies will cost 8x, and 3 video games will cost 3y.

So, we will have two equations:

2x + 5y = 35

8x + 3y = 38

We now have this system of equations, which we can solve.

Let's solve this by elimination.

To eliminate, we need to clear one of the variables, and solve for the other one.

To do this, we need to make sure that one variable has the same coefficient with opposite signs (e.g. -3x and 3x). We might need to multiply one equation by a number in order to achieve this.

We can multiply 2x + 5y = 35 by -4.

-4(2x + 5y) = -4(35)

-8x - 20y = -140

We can rewrite the equations:

-8x - 20y = -140

8x + 3y = 38

They can be added together. The result will be:

-17y = -102

Divide both sides by 017.

y = 6

We found y, but now we need to find x.

We can substitute 6 as y into 2x + 5y = 35 or 8x + 3y = 38 to find x.

Taking 2x + 5y = 35 for instance:

2x + 5(6) = 35

2x + 30 = 35

Subtract 30 from both sides.

2x = 5

Divide both sides by 2

x = 2.5

Recall that x = price of a movie, and y = price of a video game.

Therefore, a movie is 2.5 dollars, and a video game is 6 dollars.

a movie is $2.50

and a snack is $6

Answers

Answer: $158

Step-by-step explanation:

$16(8) + $24(1 ¼) = $128 + $30 = $158

Rita earned a Total of $196 for the time she worked on Monday.

To determine how much money Rita earned for the time she worked on Monday, we need to calculate her earnings for each portion of the day separately.

1. From 8:00 a.m. to 12:00 p.m. (4 hours):

Rita worked for 4 hours within the first 8 hours, so she earns her regular rate of $16 per hour for this time:

Earnings = 4 hours * $16/hour = $64.

2. From 12:30 p.m. to 6:00 p.m. (5.5 hours):

Rita worked for 5.5 hours beyond the initial 8 hours, so she earns 1.5 times her regular rate for each of these hours:

Earnings = 5.5 hours * ($16/hour * 1.5) = $132.

Now, we can sum up Rita's earnings for both periods:

Total earnings = Earnings from the first period + Earnings from the second period

Total earnings = $64 + $132

Total earnings = $196.

Therefore, Rita earned a total of $196 for the time she worked on Monday.

What are the coordinates of the image of (1, 3), where R(−3, 5) is the center of dilation with scale factor 0.5?

PLS ANSWER QUICK

Answers

Answer:

the coordinates of the image D are (-1, 4)

Step-by-step explanation:

To find the coordinates of the image D, we need to apply the dilation transformation centered at R(-3, 5). Let the scale factor be k.

The x-coordinate of D will be shifted k times the distance between 1 and -3, which is 4 units, from the x-coordinate of R, which is -3. So we have:

0.5 = -3 + k(4)

Solving for k, we get:

k = 1.375

Similarly, the y-coordinate of D will be shifted k times the distance between 3 and 5, which is 2 units, from the y-coordinate of R, which is 5. So we have

R: (x, y) = (-3, 5)

D: (x, y) = (-3 + 1.375(1 - (-3)), 5 + 1.375(3 - 5))

D: (x, y) = (-1, 4)

Therefore, the coordinates of the image D are (-1, 4), which is option D.

(-1,4) are the coordinates of the image

The translation used to create the image include the following: A. 5 units down.

What is a translation?

In Mathematics and Geometry, the translation of a geometric figure or graph to the left simply means subtracting a digit from the value on the x-coordinate of the pre-image;

g(x) = f(x + N)

Conversely, the translation a geometric figure downward simply means subtracting a digit from the value on the positive y-coordinate (y-axis) of the pre-image; g(x) = f(x) - N.

Based on the information provided, we have:

(x, y)                               →                  (x + h, y + k)

(1, -1)                              →                   (1, -6).

1 + h = 1

h = 1 - 1

h = 0

-1 + k = -6

k = -6 + 1
