Step-by-step explanation:
Two different families pay for entry into a water park.
Family 1 has 2 adults and 3 children and costs a total of £20 to enter the park.
Family 2 has 1 adult and 4 children and costs a total of £15 to enter the park.
Work out the cost of the adult ticket, and the child ticket.
Answer:
Adult ticket: $7
Child ticket: $2
Step-by-step explanation:
Set up a system of equations where a represents the cost of one adult ticket and c is the cost of one child ticket:
2a + 3c = 20
a + 4c = 15
Solve by elimination by multiplying the bottom equation by -2:
2a + 3c = 20
-2a -8c = -30
Add them together:
-5c = -10
c = 2
Now, we can plug in 2 as c to find the value of a:
2a + 3c = 20
2a + 3(2) = 20
2a + 6 = 20
2a = 14
a = 7
The solution is
The cost of one adult ticket = $ 7
The cost of one child ticket = $ 2
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the cost of one adult ticket be = x
Let the cost of one child ticket be = y
Now , for Family 1 :
2 adults and 3 children and costs a total of £20 to enter the park
Substituting the values in the equation , we get
2x + 3y = 20 be equation (1)
Now , for Family 2 :
1 adult and 4 children and costs a total of £15 to enter the park
Substituting the values in the equation , we get
x + 4y = 15 be equation (2)
On simplifying the equations , we get
Multiply equation (2) by 2 , we get
2x + 8y = 30 be equation (3)
Subtracting equation (1) from equation (3) , we get
5y = 30 - 20
5y = 10
Divide by 5 on both sides of the equation , we get
y = 2
So , the cost of one child ticket is $ 2
Now , substituting the value of y in equation (2) , we get
x + 4y = 15
x + 4 ( 2 ) = 15
x + 8 = 15
Subtracting 8 on both sides of the equation , we get
x = 15 - 8
x = 7
So , the cost of one adult ticket is $ 7
Hence , the value of x is $ 7 and value of y is $ 2

Ira fills a bottle with 16.85 ounces of water before drinking 8 ounces. Which is the most reasonable estimate for the
amount of water remaining in the bottle?
O 4 ounces
6 ounces
O 8 ounces
O 10 ounces
Answer:
8 ounces.
Step-by-step explanation:
[tex]16.85-8=8.85[/tex]
It cannot be 4 or 6 ounces as it is not likely that much water would have been wasted. It cannot be 10 ounces, as definitely more than that has been already drank. So it must be 8 ounces.
Answer:
8

PLEASE HELP ASAP FOR ALGEBRA 1 Mr Reder has just robbed a bank and is trying to escape on foot. He is currently 3 miles from the bank and running at 5 miles per hour. Write an equation to model how far from the bank Mr Reder is after a certain amount of time has passed. How far has he gone after 3 hours? Draw an appropriate graph for this equation.
Answer:
He has ran 15 miles and passed the bank 12 miles from his location where he is at.
Step-by-step explanation:
WHY WAS HE ROBBING A BANK?????????
Answer:
Step-by-step explanation:
His distance from the bank can be modeled using an equation in the form y=mx+b. Since he has already ran 3 miles, the "b" is equal to 3, and can be added to how many miles he runs on from now on. If he can run 5 miles per hour, then that means every hour, he will run 5 miles. We can represent how many hours have passed as x. This would make our equation y=5x+3.
After 3 hours he has gone 5(3)+3 miles, or 18 miles

Pls Help! Btw x = 2 is an incorrect answer!
Answer:
Option (3) x = 1
Step-by-step explanation:
f(x) represents a quadratic function as given in the graph (parabola).
Vertex of the parabola → (-2, -7)
Equation of function represented by the graph will be,
f(x) = (x + 2)² + (-7)
f(x) = (x + 2)² - 7
Option (1) For x = -1,
f(-1) = (-1 + 2)² - 7
= -6
Another function has been given as,
h(x) = 4ˣ - 3
For x = -1,
h(-1) = 4⁻¹ - 3
= 0.25 - 3
= -2.75
Option (2). For x = 0
f(0) = (0 + 2)² - 7
= 4 - 7
= -3
h(0) = 4⁰ - 3
= 1 - 3
= -2
Option (3). For x = 1,
f(1) = 9 - 7 = 2
h(1) = 4¹ - 3
= 4 - 3
= 1
Option (4).For x = 2,
f(2) = (2 + 2)² - 7
= 16 - 7
= 9
h(2) = 4² - 3
= 16 - 3
= 13
Therefore, for x = 1, function f(x) has a greater value than function h(x).
Option (3) will be the answer.
Simplify: (sec θ + tan θ) x (1 – sin θ)
Answer:
cosθStep-by-step explanation:
Given the expression (sec θ + tan θ) x (1 – sin θ), to simplify he expression the following steps must be followed. First we must know that from trigonometry identity, secθ = 1/cos θ and tanθ = sinθ/cosθ
Substituting this foremulas in the expression we will have:
(sec θ + tan θ) x (1 – sin θ)
= (1/cosθ + sinθ/cosθ)* (1-sinθ)
= (1+sinθ/cosθ) *1-sinθ
= {(1+sinθ)(1-sinθ)/cosθ}
= (1-sinθ+sinθ-sin²θ)/cosθ
= 1-sin²θ/cosθ
Also, from pythagoras therorem, sin²θ+cos²θ = 1
cos²θ = 1-sin²θ
substituting cos²θ = 1-sin²θ into the final expression above we have:
1-sin²θ/cosθ = cos²θ/cosθ
= cosθ
(sec θ + tan θ) x (1 – sin θ) = cosθ

The probability distribution was used along with statistical software to simulate 25 repetitions of the experiment (25 games). The number of hits was recorded. Approximate the mean and standard deviation of the random variable X based on the simulation. The simulation was repeated by performing 50 repetitions of the experiment. Approximate the mean and standard deviation of the random variable. Compare your results to the theoretical mean and standard deviation. What property is being illustrated?
Answer:
Hello here is the missing data to your question
x P(x)
0 0.167
1 0.3289
2 0.2801
3 0.149
4 0.0382
5 0.0368
The theoretical values are lower than the approximate values and the property illustrated is the mean and standard deviation
A) 1.6729
B) 1.234061
C) 1.84
D) 1.462874
Step-by-step explanation:
A) calculate the theoretical mean
theoretical mean (u) = summation of ; [tex]x_{i}p(x_{i})[/tex]
= 0(0.167)+1(0.3289)+2(0.2801)+3(0.149)+4(0.0382)+5(0.0369)
= 1.6729
B) calculate the theoretical standard deviation
theoretical standard deviation = [tex]\sqrt{variance}[/tex] = [tex]\sqrt{[summation of x_{i}^2 p(x_{i} ) ]-u^2}[/tex]
= [tex]\sqrt{[0+0.3289+1.1204+1.341+0.6112+0.92]-(2.798594)}[/tex]
= 1.234061
C) calculate the approximate mean
the generated data used for calculation is added below
mean (x) = [tex]\frac{summation of (x_{i}) }{n}[/tex] = [tex]\frac{1+2...+2+1}{25}[/tex] = 46/25 = 1.84
D) calculate the approximate standard deviation
std = [tex]\sqrt{variance}[/tex]
= [tex]\sqrt{\frac{summation of( x_{i}-x )^2}{n-1} }[/tex]
= [tex]\sqrt{2.14}[/tex] = 1.462874

The actual weight of the instrument is 58kg and it’s measured weight is 54kg.Find the percent error in weight. A.)6.9% B.)7% C.)7.4% D.)7.5%
Answer:
A.) 6.9%
Step-by-step explanation:
1. Percent Error = (|lab-value- actual value|/actual value) * 100
(|54 kg - 58 kg|/58 kg) * 100
(0.069) * 100 (We multiply by 100 to convert decimal to percent)
Percent Error = 6.9%
Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is . For one performance, advance tickets and same-day tickets were sold. The total amount paid for the tickets was . What was the price of each kind of ticket
Answer:
Advance tickets=$25
Same-day tickets=$15
Step-by-step explanation:
Complete question below:
Suppose that there are two types of tickets to a show: advance and same-day. The combined cost of one advance ticket and one same-day ticket is $ 40. For one performance, 25 advance tickets and 30 same-day tickets were sold. The total amount paid for the tickets was $1075 . What was the price of each kind of ticket?
Let
advance tickets=x
Same-day tickets=y
Combined cost of advance and same-day tickets=$40
It means,
x+y=40 Equ (1)
25 advance tickets and 30 same-day tickets=$1075
It means,
25x+30y=1075 Equ(2)
From (1)
x+y=40
x=40-y
Substitute x=40-y into (2)
25x+30y=1075
25(40-y)+30y=1075
1000-25y+30y=1075
5y=1075-1000
5y=75
Divide both sides by 5
5y/5=75/5
y=15
Recall,
x+y=40
x+15=40
x=40-15
=25
x=25
Advance tickets=$25
Same-day tickets=$15
Check
25x+30y=1075
25(25)+30(15)=1075
625+450=1075
1075=1075
