Gareth believes that if he flips a coin 820 times, it will land heads up exactly 410 times. What would you tell Gareth about his prediction?
Answer:
What I would tell Gareth is that his prediction is somewhat right because there is a 50/50 chance of landing the coin on each side because 410 is half of 820.

The admission ticket for Pat Pat Zoo is $1.50 for children and $4.00 for adults. On a certain day, 2200 people went to the zoo and $5050 was collected. How many children and how many adults went to the zoo that day?
Answer:
1380 children and 820 adults went to the zoo that day
Step-by-step explanation:
System of Equations
Define the following variables
x = number of children that went to the zoo
y = number of adults that went to the zoo
On a certain day, 2000 people went to the zoo, thus:
x + y = 2000
Solving for x:
x = 2000 - y [1]
The admission ticket is $1.50 for children and $4.00 for adults and that same day, $5050 was collected, then:
1.50x + 4y = 5050 [2]
Substituting x from [1]:
1.50(2000 - y) + 4y = 5050
Operating:
3000 - 1.50y + 4y = 5050
3000 + 2.5y = 5050
Subtracting 3000
2.5y = 5050 - 3000 = 2050
Dividing by 2.5
y = 820
From [1]
x = 2200 - 820 = 1380
1380 children and 820 adults went to the zoo that day

Can somebody solve this: x^4+2x^3-25x^2-26x+120
Answer:
(x + 5) • (x + 3) • (x - 2) • (x - 4)
Step-by-step explanation:
Step-1 : Multiply the coefficient of the first term by the constant 1 • 15 = 15
Step-2 : Find two factors of 15 whose sum equals the coefficient of the middle term, which is 8 .
-15 + -1 = -16
-5 + -3 = -8
-3 + -5 = -8
-1 + -15 = -16
1 + 15 = 16
3 + 5 = 8 That's it
Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, 3 and 5
x2 + 3x + 5x + 15
Step-4 : Add up the first 2 terms, pulling out like factors :
x • (x+3)
Add up the last 2 terms, pulling out common factors :
5 • (x+3)
Step-5 : Add up the four terms of step 4 :
(x+5) • (x+3)
Which is the desired factorization
(x + 5) • (x + 3) • (x - 2) • (x - 4)

which system of linear inequalities is represented by the graph?
Answer:
C
Step-by-step explanation:
Use the elimination method to solve the following system of equations:
2x+y=3
3x – y= 12
The solution is
x = 3
y = -3
(3, -3)
Step-by-step explanation:
Choose one of the equations and isolate y. I will use the first one.
2x + y = 3
Y = 3 - 2x
Now sub the solution for y into the equation below.
3x - y = 3
3x - (3 - 2x) = 12
3x - 3 + 2x = 12
5x - 3 = 12
5x = 15
x = 3
To get y, sub the answer for x into one of the equations.
2(3) + y = 3
6 + y = 3
y = 3 - 6
y = -3
Answer:
(x,)y) =(3,-3)
Step-by-step explanation:
add the equations vertically to eliminate one variable
2x +y = 3
3x -y = 12
5x =15 divide both sides by 5
x = 3 now substitute the given value of x into the equation 2x+y=3
2 x 3 + y = 3 multiply 2x3
6 +y =3 move constant to the right
y = 3-6
y = -3
click on the measurements that is equal to 20 cups.
Measurement of 5 quarts is equal to 20 cups.
What are Measurements?Measurement is the method of comparing the properties of a quantity or object using a standard quantity.
Measurement is essential to determine the quantity of any object.
We have the measurement, 1 cup = 1/4 quarts
Let x be the number of quarts for 20 cups.
By using proportion,
1 / (1/4) = 20 / x
Cross multiplying,
x = 20 × (1/4)
x = 5
Hence the measurement of 20 cups is equal to 5 quarts.

41/19 as a decimal rounded to the nearest hundredth
The decimal rounded to the nearest hundredth is 2.16
What is Decimal?A group of numbers between integers on a number line are known as decimals. They are merely an additional mathematical representation of fractions. Decimals allow us to express measurable quantities like length, weight, distance, money, etc. with greater accuracy. Integers, also known as whole numbers, are represented to the left of the decimal point, while decimal fractions are represented to the right of the decimal point. The next place, which is (1/10)th or tenth place value, is (1/10) times smaller if we move immediately from the first place.
Given:
41/19
Now, dividing the fraction
41/19
= 2.1578
Now, rounding off to nearest hundredth focus on thousandth place value whether it is greater than 5 or not.

A 5 feet
B 5 feet 1 inch
C 5 feet 2 inches
D 5 feet 3 inches
E 5 feet 4 inches
F 5 feet 5 inches
Answer:
Add up all of the numbers in the set and then divide by how many numbers there are.
Step-by-step explanation:
I'm not sure if that's the most conventional way- but it's how I learned.
Here's your set of numbers:
4'11, 5'0, 5'0, 5'1, 5'2, 5'2, 5'3, 5'4, 5'4, 5'4, 5'4, 5'4, 5'5, 5'5, 5'6
And here's that same set of numbers in inches (which is what I'd use to find it out):
59, 60, 60, 61, 62, 62, 63, 64, 64, 64, 64, 64, 65, 65, 66
Which adds up to a total number of 15 numbers in the set.
Add up 59, 60, 60, 61, 62, 62, 63, 64, 64, 64, 64, 64, 65, 65, 66.
That's 943.
Then we divide 943 by how many numbers there are in the set (15).
The mean of your set is 62.8666667.
Round to the nearest whole number, making it 63.
How many feet is 63 inches?
