Answer: 4/5 = 180/b; b = 225 boys
Answer:
Given that there are 4 boys for every 5 girls, we can set up the following proportion:
4/5 = x/180
where x is the number of boys.
To solve for x, we can cross-multiply:
5x = 4 * 180
5x = 720
x = 144
Therefore, there are 144 boys.

14 adults and 20 children attended a piano recital. If two people are selected to receive door prizes at the recital, what is the probability that both will be children? Write your answer as a fraction and a decimal rounded to the nearest hundredth.
Answers
Answer: 0.34
Step-by-step explanation:
From the question, 14 adults and 20 children attended a piano recital. This means that there are 14 + 20 = 34 people who attended the paint recital.
If two people are selected to receive door prizes at the recital, the probability of selecting the first child will be 20/34 while the second child will be 19/33. To get the probability of both being children, we have to multiply the fractions
= 20/34 × 19/33
= 380/1122
= 0.34

Sandy's experimental probability was closest to the theoretical probability in the experiment with 500 flips.
Sandy's experimental probability was closest to the theoretical probability in the experiment with 1,000 flips.

Answer:
As the flips increase, the experimental probability should get closer to the theoretical probability. Meaning that the trial with 1000 coin flips should be closest to the theoretical probability, Hope this helps lmk if its correct
Answer:
the probability of flipping a coin and it landing on heads and tails are 50/50 because theres 2 options.
if you flip it 100 times the probability would be 40-60 percent of the flips would land on heads OR tails

Roxie is a show dog her trainer wants her to have a beautiful and brilliant coat. The veterinarian suggested a special diet for the trainer to follow each feeding Roxie eats 2/3 of a can of wet dog foods 1/8 of a bag of dry food and 3/5 a patty of special meat the special meat comes in a package of 6 patties Roxie has two meals a day
Answers
Answer: the answers are below
Step-by-step explanation:
1 meal = 2/3 of a can of wet dog food, 1/8 of a bag of dry dog food, and 3/5 a patty of special meat
Food for 1 day: 2 meals = 2(2/3) = 4/3 of a can of wet dog food, 2(1/8) = 1/4 of a bag of dry dog food, and 2(3/5) = 6/5 a patty of special meat
The trainer goes to the store and buys 24 cans of wet food, 4 bags of dry food and 3 packages of meat (3*6 = 18 patties)
He has:
there is wet food for: 24/(4/3) = 24*3/4 = 18 days
there is dry food for: 4/(1/4) = 4*4 = 16 days
there is special meat food for: 18/(6/5) = 18*5/6 = 15 days
since the minimum for 15, 16 and 18 is 15 the dog will have food for 15 days and first he will run out of special meat.
1. Roxie will be fed for 15 days before the trainer needs to buy more food.
2. The trainer will run out of the special meat first, as it will last for 15 days.
3. After the special meat runs out, there will be 3 cans of wet food and 1 bag of dry food left.
4. The trainer needs to buy 96 more cans of wet food, 19 more bags of dry food, and 36 more patties of special meat to last 90 days.
5. The minimum amount of food the trainer could buy is 80 cans of wet food, 15 bags of dry food, and 72 patties of special meat, which would last for 60 meals (30 days).
Step 1: Calculate the daily consumption of each type of dog food.
Wet food: 2/3 can per meal * 2 meals per day
= 4/3 cans per day.
Dry food: 1/8 bag per meal * 2 meals per day
= 1/4 bag per day.
Special meat: 3/5 patty per meal * 2 meals per day
= 6/5 patties per day.
Step 2: Calculate the total food available for Roxie.
Wet food: 24 cans purchased.
Dry food: 4 bags purchased.
Special meat: 3 packages (3 * 6 patties = 18 patties) purchased.
Step 3: Calculate the number of days the food will last.
Days of wet food: 24 cans / (4/3 cans per day)
= 24 * 3/4
= 18 days.
Days of dry food: 4 bags / (1/4 bag per day)
= 4 * 4
= 16 days.
Days of special meat: 18 patties / (6/5 patties per day)
= 18 * 5/6
= 15 days.
Step 4: Determine which type of dog food will run out first.
The special meat will run out first, after 15 days.
Step 5: Calculate how much of the other two types of dog food will be left after the first type runs out.
After 15 days, Roxie will still have
= 18 - 15
= 3 cans of wet food left.
After 15 days, Roxie will still have
= 16 - 15
= 1 bag of dry food left.
Step 6: Plan for 90 days.
The total number of patties needed for 90 days
= (6/5 patties per day) * 90 days
= 108 patties.
and, the trainer needs to buy
= 108 / 6 = 18 packages
- For wet food, Roxie needs
= (4/3 cans per day) * 90 days
= 120 cans.
The trainer already has 24 cans, so she needs to buy
= 120 - 24 = 96 more cans.
- For dry food, Roxie needs
= (1/4 bag per day) * 90 days = 22.5 bags.
Since the trainer can't buy half a bag, she needs to round up to 23 bags.
Step 7: Minimum amount of food to buy to finish all of it after a certain number of meals.
Minimum amount of wet food to buy:
= (4/3 cans per day) * 60
= 80 cans.
Minimum amount of dry food to buy:
=(1/4 bag per day) * 60
= 15 bags.
Minimum amount of special meat to buy:
=(6/5 patties per day) * 60
= 72 patties.
Therefore, the trainer could buy a minimum of 80 cans of wet food, 15 bags of dry food, and 72 patties of special meat, and Roxie would finish all of it after 60 meals (30 days).

Leon is scuba diving at an elevation of −72
feet when his friend signals to come higher to see a sea turtle. Leon makes 3 ascents, each an equal distance, to reach an elevation of −18
feet, where the sea turtle is located.
What was Leon's elevation after his second ascent?
Answers
Answer: -36 feet
Step-by-step explanation:
72-18 = 54 feet ascended
54 feet / 3 ascents = 18 feet per ascent
18 feet * 2 ascents = 36 feet
-72+ 36 = -36 feet
54/3= 18, 18*2=36
72-36= 36

The function for the points are y = -15x - 5
How to determine the functionFrom the information given, we have that;
The points are;
(1/3,0) (-2 3/4,0) and (0,-5)
Using the point-slope form of a linear equation, we have;
y - y₁ = m(x - x₁)
Such that;
m is the slope of the liney - y₁ and (x - x₁) are the pointsUsing (1/3, 0) and (0, -5), we have that the slope is;
m = (0 - (-5))/0 -1/3)
expand the bracket
= 5 / (-1/3)
= -15
Now, take any of the given points and substitute the values
Using (1/3, 0), we get;
y - 0 = -15(x - 1/3).

The function for the points solved by (1/3,0) (-2 3/4,0) and (0,-5) solved by point slope form is \(a=-15b-5\)
We have given the points:
(1/3,0) (-2 3/4,0) and (0,-5)
Using the formula of linear equation
\(a-\)\(a_{1}\)\(=x[b-b_{1}]\)
Where we will consider (1/3,0) = \(a-a_{1}\) and (0,-5) = \(b-b_{1}\)
that is 1/3 = \(a\), 0 = \(a_{1}\) and
0 = \(b\), -5 = \(b_{1}\)
\(x\) refers to the slope of line (take any variable)
Now for finding the value of \(x\),
\(x=a-a_{1}/b-b_{1}\)
inserting the values,
\(x=[0-[-5]]/[0-1/3]\\x= -15\)
Substitute the value of \(x\) in the equation
\(a-0=-15[b-1/3]\)
By simplifying the equation, we get
