HURRY 20 POINTS

Mrs. Bready has a large bag filled with red and green cards. She tells the class that 15% of the cards are red and
85% are green. At the end of each class, she mixes the cards, reaches inside the bag, and draws out one card at
random. If a red card is drawn, the students will not be assigned homework. She shows the class the card, and
then places the card back in the bag. Carla would like to carry out a simulation to estimate the number of days it
will take in order to get a "no homework" day. She assigns the digits to the outcomes.
00-14 = red
15-99 = green

Beginning at line 1 and starting each new trial right after the previous trial, carry out 5 trials of this simulation
Based on these 5 trials, what is the average number of days it will take to get a "no homework" day?
A) 2
B) 2.8
C) 3.4
D) 4.2

Answers

Answer 1

It will take 4.2 days in order to get a "no homework" day.

Averages

To determine the average number of days that it will take in order to get a "no homework" day, based on these 5 trials, the following calculation must be performed:

0.85 x 0.85 x 0.85 x 0.85 x 0.85 = X0.4437 = X

Therefore, it will take 4.2 days in order to get a "no homework" day.

simultaneous equations find x and y
2x/ y + y/ x =3
3x-y=2​

Answers

Answer:

x = 1 and y = 1

Step-by-step explanation:

2x/y + y/x = 3

3x - y = 2

we first of all get the simple equation from the two equations and in this case we will use substitution method

3x - y = 2

then we make y the subject of the formula

y = 3x - 2

let's use y on the top equation to substitute

2x/y + y/x = 3

2x/3x - 2 + 3x - 2/x

like terms cancel

thus:

2x/1 + 1/x = 3

3x -2x = 1

x = 1

AND

AND since we have x, we still use substitution method to find y

3x - 2 = y

3 (1) - 2 = y

3 - 2 = y

y = 1

One species of fish in a fishery had an initial population of 255 fish and grew by 25 fish each season. A second species that was being overfished started with an initial population of 450 fish, and then decreased by 40 fish each season. Assuming a linear change, write equations for the populations of each species. When will the two populations have the same amount of fish? After how many seasons will the second species be eliminated?

Answers

Answer:

they intersect at 3.5 seasons, 312 fish. the second gets elimed at 11 seasons

Step-by-step explanation:

A bag contains 7 green marbles,2 white marble s, 5 orange marbles,9 blue marbles, and 7 red marbles. a marble will be drawn from the bag and replaced 180 times what is a reasonable prediction for the number of times a white or red marble will be drawn?

Answers

The reasonable probability that a white or red marble will be drawn all 180 times is; (3/10)¹⁸⁰.

Probability with replacement

Since the probability is with replacement;

First, the total number of marbles in the bag is; 7+2+9+5+7 = 30.

Hence, the probability that a white or red ball is drawn each time is; 2+7 = 9 possible outcomes.

Hence, it follows that the probability for white or red each time is; 9/30 = 3/10

Hence, when drawn 180 times, the probability is;

P = (3/10)¹⁸⁰.

The number of messages posted each day on an online message board during the first 5 days it was open are listed below

2,350 2,900 3,450 4,000 4,550

The number of messages posted each day follows a pattern. Which expression can be used to determine the number of messages

posted on the nth day?

O A. 2,350n

ов.

550(n + 1,800)

O C.

550n + 1,800

O D.

1,800n + 550

Answers

= C, 550n + 1800

Here is how you make a expression for a sequence:

1) Firstly, identify the number gap. This is 550. 2350 + 550 = 2900. 2900 + 550 = 3450, ect. So this means that it is 550n.

2) n is basically just the number in the sequence it stands on. n for 2350 is 1. So now you need to know what you must add to 550n to get whatever n is. We will choose 2350. n is 1 for it. 550 x 1 = 550. 2350 - 550 = 1800. So it is 550n + 1800.

What are the coordinates of the point (-3, 0) after a translation 2 units up?

A. (-3,2)
B. (-5,0)
C. (-3,-2)
D. (-1,0)

Answers

Answer: (-3,2)

Step-by-step explanation:

It's a translation 2 units UP, which means vertically, which means the Y Axis, so your (-3,0) which is formatted like: (x,y) would add 2 to the y variable of the coordinate -> (-3,2), You don't even need a graph for this problem tbh.

The coordinates of the (-3, 0) after a translation 2 units up is: A. (-3, 2).

What is Translation?

Translation is a form of transformation, whereby the points of a figure is moved from one position to another by the same distance in a given direction.

Given a point, (-3, 0), after translation 2 units up, that is, 2 units up along the vertical axis (y-axis), we would have:

(-3, 0 + 2 units) = (-3, 2).

Thus, the coordinates of the (-3, 0) after a translation 2 units up is: A. (-3, 2).
