A=adult pay
c=child pay
3a+4c=83
2a+3c=59
subtract
a+c=24
2a+2c=48
2a+3c-2a-2c=59-48
c=11
a=24-11=13
price of adult ticket=13$
price of child's ticket=$11

Let x and y represent the costs of adult and child tickets, respectively. Then the problem statement gives two relations:
.. 3x +4y = 83
.. 2x +3y = 59
A graph shows the solution to be (x, y) = (13, 11).

The price of a child's ticket is $11.
The price of the adult ticket is $13.

!Will mark BRAINILEST! What's the type of function that represents this pattern??

Exponentially growth.

Let’s say one person starts with the flu. After the first day, there are suddenly

1 x 2 = 4 people sick

And the rest of the days just explode in magnitude:

Day 2: 1 x 2 x 2 = 8 people sick
Day 3: 1 x 2 x 2 x 2 = 16 people sick
Day 4: 1 x 2 x 2 x 2 x 2 = 32 people sick
Etc.

You can rewrite all that repeated multiplication as *exponents*, which is why we call it exponential growth.

Day 1: 1 x 2^1 = 4
Day 2: 1 x 2^2 = 8
Day 3: 1 x 2^3 = 16

And after n days, 1 x 2^n - or just 2^n - people would be sick.

Convert 90.1% to a fraction in simplest form

g100num [7]

The 90.1 percent can be written as a fraction in the simplest form is 901/1000.

<h3>What is percentage?</h3>

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

We have a percentage 90.1%

To convert it into the fraction in the simplest form we can do as follows:

= 90.1%

$= \dfrac{90.1}{100}$

= 0.901

$= \dfrac{901}{1000}$

Thus, the 90.1 percent can be written as a fraction in the simplest form is 901/1000.

Answer:

B) Jill omitted a factor pair, which affected the GCF and factored expression.

Step-by-step explanation:

Jill is factoring the expression 13xy-52y. Her work is shown below.

Factors of 13xy: 1, 13, x, y

Factors of 52y: 1, 2, 26, 52, y OOPSIE she forgot 4,13

GCF: y

Factored expression: y(13x-52) 13y (x-4)

In a valid probability distribution, each probability must be between 0 and 1, inclusive, and the probabilities must add up to 1

lora16 [44]

The value of x is 1/5

Step-by-step explanation:

In a probability distribution, probability should be between 0 and 1. The probabilities add up to one.

Given probabilities are:

$\frac{1}{10}, \frac{1}{5}, \frac{1}{2}, x$

The sum of these probabilities will be equal to 1.

So,

To find x,

$\frac{1}{10}+\frac{1}{5}+\frac{1}{2}+x = 1\\\frac{1+2+5}{10}+x=1\\\frac{8}{10}+x=1\\x= 1- \frac{8}{10}\\x = 1- \frac{4}{5}\\x= \frac{5-4}{5}\\x=\frac{1}{5}$
