(3,1) is the solution. When u plug in 3 for x and 1 for y you find that this is the only pair that works

NEED HELP ASAP!!!! PLEASE HELP!!!!!!!!!!!!!!!

Answers

Answer:

y = 14

x = 10

Step-by-step explanation:

Here, we want to get the value of x and y

Since all sides are equal, then the measure of each angle is 60 degrees

Since AC = 14

y is also 14

Also;

Since each angle is 60

Then;

6x = 60

x = 60/6

x = 10

80 + ? + -30 = 0 whats in the middle

Answers

Answer: The answer is -50

because 80 + -50 = 30 and 30 + -30= 0              .

how many soulitons?? 4x-6=2(2x-3)

Answers

Ans: All real numbers are solutions.

Given the function below, find x if f(x)=11
f(x) = 3x + 5

Answers

x = 2
plug in 11 into f(x) and you get 11 = 3x + 5
subtract 5 from both sides and you get 6 = 3x
divide 3 from both sides and you get x = 2
if you plug in 2 for x, you should get 11.

2) What is the length of BD and BC in the diagram below?
D(14.14)
C(11.10)
B (5.2)

please help me

Answers

Answer:

BC is 10 unit

BD is 15 units

Step-by-step explanation:

Here, given the end points of the line segments, we want to calculate BD and DC

Mathematically, the distance between two points can be calculated using the formula;

D = √(x2-x1)^2 + (y2-y1)^2

For BD, we have the following

D = √(14-5)^2 + (14-2)^2

D = √(9)^2 + 12^2

D = √81 + 144

D = √(225)

Distance BD is 15 units

For BC, we have the following

D = √(11-5)^2 + (10-2)^2

D = √(6)^2 + 8^2

D = √100

D = 10

There were 239 people at Travis Scott concert.Admission to get the drive in concert was $15 for adults and $5.50 for children the total cost was 2759.50 how many adults attended and how many children attended

Answers

Answer: There are 152 adults and 87 children.

Step-by-step explanation:

Let x= Number of adults

y= Number of children

As per given, we have

x+y = 239                 (i)

15x+5.50y= 2758.50              (ii)

Multiply 5.50 on both sides of (i) , we get

5.50x+5.50y=1314.5             (iii)

Subtract (iii)  from (ii), we get

9.5x = 1444

⇒  x = 152

Put value of x in (i) , we get

152+y=239

⇒ y= 239-152

⇒ y= 87

Hence, there are 152 adults and 87 children.

What is a cumulative distribution function?

The probability distribution of random variables is described using the cumulative distribution function. The probability for a discrete, continuous, or mixed variable may be described using it. The cumulative probability for a random variable is calculated by adding the probability density function.

Given:

A coin is flipped 500 times.

The probability when the coin is flipped once,

= 1/2

= 0.5

we want P (X ≤ 450), and this will use a binomial cumulative distributive function,

the parameters of a binomial cumulative distributive function are,

binomcdf (total trials, probability, up to some number)

That means,

binomcdf(500, 0.5, 450)

Therefore, binomcdf(500, 0.5, 450) is the required expression.
