80 men and 60 women are enrolled in calculus. There are 40 business majors, 30 biology majors, 15 computer science majors, and 5 mathematics majors. No person has double major. If a single calculus student is chosen, find the following probabilities
The probability of selecting a male calculus student is approximately 57.14%, a female calculus student is approximately 42.86%, a business major calculus student is approximately 28.57%, a biology major calculus student is approximately 21.43%, a computer science major calculus student is approximately 10.71%, and a mathematics major calculus student is approximately 3.57%.
To find the probabilities, we will use the formula:
Probability of an event = (Number of favorable outcomes) / (Total number of possible outcomes)
Probability of selecting a male calculus student:
There are 80 male students in calculus, so the probability of choosing a male student is:
Probability (Male) = 80 / (80 + 60) = 80 / 140 ≈ 0.5714 or 57.14%
Probability of selecting a female calculus student:
There are 60 female students in calculus, so the probability of choosing a female student is:
Probability (Female) = 60 / (80 + 60) = 60 / 140 ≈ 0.4286 or 42.86%
Probability of selecting a business major calculus student:
There are 40 business majors in calculus, so the probability of choosing a business major student is:
Probability (Business Major) = 40 / 140 ≈ 0.2857 or 28.57%
Probability of selecting a biology major calculus student:
There are 30 biology majors in calculus, so the probability of choosing a biology major student is:
Probability (Biology Major) = 30 / 140 ≈ 0.2143 or 21.43%
Probability of selecting a computer science major calculus student:
There are 15 computer science majors in calculus, so the probability of choosing a computer science major student is:
Probability (Computer Science Major) = 15 / 140 ≈ 0.1071 or 10.71%
Probability of selecting a mathematics major calculus student:
There are 5 mathematics majors in calculus, so the probability of choosing a mathematics major student is:
Probability (Mathematics Major) = 5 / 140 ≈ 0.0357 or 3.57%

Javier’s fuel tank holds 12 3⁄4 gallons of gasoline when completely full. He had some gas in the tank and added 10.3 gallons of gasoline to fill it completely.
How many gallons of gasoline were in the tank before Javier added some?
The number of gallons of gasoline in the tank before Javier added some is 2 3/4 gallons.
1. Subtract 10.3 gallons (the amount he added) from 12 3/4 gallons (the total capacity of the tank).
2. Calculate 12 3/4 - 10.3 to find the remaining amount of gasoline in the tank.
To subtract mixed numbers, we first convert them into improper fractions:
[tex]\[ 12 \frac{3}{4} - 10 \frac{3}{10} \][/tex]
[tex]\[ = \frac{(12 \times 4) + 3}{4} - \frac{(10 \times 10) + 3}{10} \][/tex]
[tex]\[ = \frac{48 + 3}{4} - \frac{100 + 3}{10} \][/tex]
[tex]\[ = \frac{51}{4} - \frac{103}{10} \][/tex]
To subtract fractions, we need a common denominator. Here, the least common denominator (LCD) is 20.
[tex]\[ = \frac{51 \times 5}{4 \times 5} - \frac{103 \times 2}{10 \times 2} \][/tex]
[tex]\[ = \frac{255}{20} - \frac{206}{20} \][/tex]
[tex]\[ = \frac{255 - 206}{20} \][/tex]
[tex]\[ = \frac{49}{20} \][/tex]
Now, we convert the improper fraction back to a mixed number:
[tex]\[ = 2 \frac{9}{20} \][/tex]
Therefore, Javier had 2 9/20 gallons of gasoline in the tank before adding more.
Javier had 2.45 gallons of gasoline in his tank before he added 10.3 gallons to fill it to its full capacity of 12.75 gallons.
To find how many gallons of gasoline were in Javier's tank before he added some, we need to subtract the amount he added from the total capacity of the tank. Javier's fuel tank can hold 12 3/4 gallons when full, which is equal to 12.75 gallons. He added 10.3 gallons to fill it up. Therefore, the amount of gas in the tank before he added more can be calculated as follows:
Amount of gasoline initially in the tank = Total capacity - Amount added
Amount of gasoline initially in the tank = 12.75 gallons - 10.3 gallons
Amount of gasoline initially in the tank = 2.45 gallons
Thus, Javier had 2.45 gallons of gasoline in the tank before he added the 10.3 gallons.

The length of the minute hand is 150% of the length of the hour hand.
In one hour, how much farther does the tip of the minute hand move than the tip of the hour hand? Round your answer to the nearest tenth.
In an hour, the minute hand, which is 1.5 units long, travels a full revolution or approximately 9.4 units, while the hour hand, 1 unit long, covers one-twelfth, or about 0.5 units. Therefore, the minute hand travels approximately 7.9 units more than the hour hand.
Explanation:This question can be solved by first examining the distance each hand travels. In an hour, the minute hand completes a full revolution around the clock face, moving a distance equal to the clock's circumference. If we call the length of the minute hand 1.5 units, then its distance traveled is 2π(1.5).
In contrast, the hour hand moves onto the next hour, covering on-twelfth of the clock's face, or 2π(1/12) using a length of 1 unit for the hour hand. Substract the second measure from the first to find the difference. Thus, the minute hand travels about 7.9 units farther than the hour hand.

Billy left home at 9:00 a.m. and rode his bike to the park at an average speed of 10mph. He arrived at the park at 9:30. How many miles from the park is Billy’s house.
The solution is:
Park is 5 miles from Billy's home.
What is speed?Speed is measured as distance moved over time. The formula for speed is speed = distance ÷ time. To work out what the units are for speed, you need to know the units for distance and time. In this example, distance is in metres (m) and time is in seconds (s), so the units will be in metres per second (m/s).
Speed = Distance/ Time.
Given:
Billy left home at 9 a.m. And rode his bicycle to the park at an average speed of 10 miles per hour here and got the park at 9:30 a.m.
Now, to find the distance from park to Billy,s home.
Time it took Billy to rode his bicycle from park to home is from 9.30 a.m to 9.30 p.m.
So, the time = (9.30 - 9.00) = 30 minutes
Speed = 10 miles per hour.
Now, to get the distance from park to Billy's home we put formula:
Speed = Distance/ Time.
so, we get,
Distance = 10 * 0.5
= 5
Therefore, park is 5 miles from Billy's home.

The probability of a certain hockey player making a goal after hitting a slap shot is 1/5. How many successful slap shot would you expect her to make after 120 attempts?
-5
-20
-24
-60
I need help with Getting the answer! Help please!
We know that the probability of a certain hockey player making a goal after hitting a slap shot is [tex]\frac{1}{5}[/tex].
We need to figure out the number of successful slap shots if she makes 120 attempts?
Since the player is able to make a goal once out of 5 attempts. Therefore, in order to find the number of goals that we can expect the player to make successfully if she attempts 120 slap shots we will multiply the probability with 120.
Number of successful goals = (Probability of making one goal)x(Number of attempts)
Number of successful goals = [tex]\frac{1}{5}\times 120 = 24[/tex].
Therefore, player will be able to make 24 goals out of 120 attempts.

The stem and leaf plot below shows the number of points scored in each basketball game a team played during a season
From the stem and leaf plot , We have 4 leaf for the stem 4
so the scores are 44, 45, 48, 49
Question says more than 40 points scored. so we consider stem 5 and 6 as well
61, 66, 67
5 2, 52, 58
So total 10 scores
There were 10 games in which the basketball team scored more than 40 points.
The stem and leaf plot provided shows the scores of a basketball team across different games. To find out in how many games more than 40 points were scored, we should look for leaves attached to stems of '4' or higher, since the stems represent the 'tens' place and the leaves represent the 'ones' place in a score.
In the stem '4', we have leaves '4', '5', '8', and '9', which correspond to the scores 44, 45, 48, and 49, respectively. Moving up to the stem '5', we have leaves '2', '2', and '8', which translate to the scores 52, 52, and 58. Finally, the stem '6' with leaves '1', '6', and '7' represents the scores 61, 66, and 67.
Adding all the games with scores over 40 points together, we get a total of 4 (from the '4' stem) + 3 (from the '5' stem) + 3 (from the '6' stem) = 10 games.
