Each person at a
baseball game receives 3 raffle tickets
and a $2 certificate for the team store.
A group of people receives 39 raffle
tickets. How much money in certificates
does the group receive?
In a case whereby baseball game receives 3 raffle tickets and a $2 certificate for the team store. A group of people receives 39 raffle tickets the amount of money in certificates the group receive is $26.
How can this be calculated?If one baseball game receives 3 raffle tickets and a $2 certificate for the team store, then we can say that each raffle ticket is worth 2/3 dollars ($2 divided by 3 tickets).
So, for 39 raffle tickets, the group would receive (39 x 2/3) = $26
Therefore, the amount of money in certificates the group receive is $26

A dot chart, also known as a dot plot, is a type of statistical chart that consists of data points shown on a very basic scale, generally utilising filled in circles. The dot chart has two common but quite distinct variants. The first has been used to show distributions in hand-drawn graphs since 1884.

What is the probability that the animal's weight will be less than
151 pounds?
O 0.25
O 0.50
O 0.60
O 0.75
The probability that the animal's weight will be less than 151 pounds is 0.50.
The correct option is B.
What is the probability that the animal's weight will be less than 151 pounds?Since the given probability distribution ranges from 148 to 152, and we need to find the probability that the animal's weight will be less than 151 pounds, we can add the probabilities corresponding to the weights less than 151.
From the distribution, we see that the probability of the animal's weight being less than 151 pounds is 0.2 + 0.3 = 0.5.

The sum of a number and 3 is less than or equal to 8
Answer:
m ≤ 5
Step-by-step explanation:
I will begin by assuming m to be the number.
Then, the sum of m and 3 is: m + 3.
The symbol for "less than or equal to" is ≤.
So we form an inequality, like this :
m + 3 ≤ 8
To find m subtract 3 on each side:

Leila has a deck of 10 cards numbered 1 through 10 . She is playing a game of chance.
This game is this: Leila chooses one card from the deck at random. She wins an amount of money equal to the value of the card if an even numbered card is drawn. She loses $6 if an odd numbered card is drawn.
(a) Find the expected value of playing the game.
(b) What can Leila expect in the long run, after playing the game many times?
(She replaces the card in the deck each time.)
Leila can expect to gain money.
Leila can expect to lose money.
Leila can expect to break even (neither gain nor lose money).
a. The expected value is $12
b. She is expected to win money
What is the expected value of playing the game?To find the expected value of playing the game, we need to calculate the average value of the winnings or losses.
(a) Expected Value:
The probability of drawing an even-numbered card is 5/10 (since there are 5 even-numbered cards out of 10), and the probability of drawing an odd-numbered card is also 5/10.
If Leila draws an even-numbered card, she wins an amount equal to the value of the card. So the expected value of winning is:
(5/10) * (2 + 4 + 6 + 8 + 10) = (5/10) * 30 = 15/10 = $15
If Leila draws an odd-numbered card, she loses $6. So the expected value of losing is:
(5/10) * (-6) = -3
To find the overall expected value, we subtract the expected value of losing from the expected value of winning:
Expected value = (15) + (-3) = 12
Therefore, the expected value of playing the game is $12
(b) In the long run, after playing the game many times, Leila can expect to lose money. Since the expected value is positive $12 , on average, she will win $12 per game.

This image shows that when a football is kicked, the nearest defensive player is 6 feet from the kicker’s foot. The height of the punted football, f(x), in feet, can be modeled by the equation. Round all answers to 2 decimals. ()=−0.0152 +1.25+2 a. (2 points) What is the maximum height of the punt?
Using the vertex, it is found that the maximum height of the punt is of 27.7 feet.
The height of the punt, after x seconds, is given by:
\(f(x) = -0.0152x^2 + 1.25x + 2\)
It is a quadratic equation with coefficients \(a = -0.0152, b = 1.25, c = 2\).
The maximum value is the value of the function at the vertex, hence:
\(f_V = -\frac{\Delta}{4a} = -\frac{b^2 - 4ac}{4a}\)
Applying the coefficients:
\(f_V = -\frac{b^2 - 4ac}{4a} = -\frac{(1.25)^2 - 4(-0.0152)(2)}{4(-0.0152)} = 27.7\)
The maximum height of the punt is of 27.7 feet.

(4, 12)
Answer:
D. (4,12)
Step-by-step explanation:
Though I cannot see the image, I know what the answer is. The original points at (4, 7), and going up would mean that the y coordinate is getting higher.
(4, 7)=(x, y)
(x, y) = (4, 7)
7+5=12
Since 7 plus 5 is twelve, the new y coordinate is 12. Since we are not going the left or right, the x would stay the same.
Remember! You crawl (x) before you walk (y). Left/right means the x changes, up/down means the y changes.

• Jesse:
Reads 30 pages per day
• Amir
Reads 35 pages per day
So, for Amir, the number of days will be x, and y will be the number of pages read in total:
y = 35x
Since he reads 35 pages per day = 35x
For Jesse, since she already started on Saturday, she has a 1-day advantage.
Days = (1+x)
y = 30 (1+x)
Equal both equations:
35x=30(1+x)
Solve for x (days to catch up)
35x= 30(1)+ 30(x)
35x= 30+30x
35x-30x=30
5x=30
x=30/5

this is about the volume of each size of candle. so the area of the circle , times the height of the candle is the amount of wax needed or it's volume.
area of a circle is = \(\pi\)\(r^{2}\)
then the big candle is \(\pi\)\(2^{2}\) = 12.56637
times 10 for it's height = 125.6637
so that's the big candles volume
then make 20 of those = 2513.27
a small candle is \(\pi\)\(1.5^{2}\) = 7.068583471
and it's 6 cm tall so times 6 = 42.41150082
Now divide the small candle volume into the 20 big ones to see how many small ones can be made
2513.27 / 42.41150082 = 59.259
so just a bit over 59 small candles can be made from 20 big candles

M is the slope in slope intercept form.
y=mx+b
And b is the Y intercept because when you plug in zero for x you get y=b.

Because m is the slope
And y is 6 because it is shown in the parentheses

The temperature in a hotel is 21 °C.
The temperature in the hotel is 26,7°C warmer than at the top of the mountain.
The temperature at the top of the mountain is 3.2°C colder than at the bottom of the mountain.
Work out the temperature at the bottom of the mountain.
The temperature at the bottom of the mountain is 50.9 °C.
Let's work through the given information step by step to find the temperature at the bottom of the mountain.
The temperature in the hotel is 21 °C.
The temperature in the hotel is 26.7 °C warmer than at the top of the mountain.
Let's denote the temperature at the top of the mountain as T_top.
So, the temperature in the hotel can be expressed as T_top + 26.7 °C.
The temperature at the top of the mountain is 3.2 °C colder than at the bottom of the mountain.
Let's denote the temperature at the bottom of the mountain as T_bottom.
So, the temperature at the top of the mountain can be expressed as T_bottom - 3.2 °C.
Now, let's combine the information we have:
T_top + 26.7 °C = T_bottom - 3.2 °C
To find the temperature at the bottom of the mountain (T_bottom), we need to isolate it on one side of the equation. Let's do the calculations:
T_bottom = T_top + 26.7 °C + 3.2 °C
T_bottom = T_top + 29.9 °C
Since we know that the temperature in the hotel is 21 °C, we can substitute T_top with 21 °C:
T_bottom = 21 °C + 29.9 °C
T_bottom = 50.9 °C
Therefore, the temperature at the bottom of the mountain is 50.9 °C.
