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.

Answer:

2.5

Step-by-step explanation:

50÷4-10

50=(4x)-10

Equation:

(4*n)=50

Solution:

(4*n)-10=50

(4*n)-10-10=50-10

(4*n)=40

4*10=40

n=40

Answer:

y=x doesent that mean 2=3 so what you do is the line that goes up thats y and the one that goes sideways thats x so at the to go to 2 then at the side go to 3

Answer:

Step-by-step explanation:

y=x doesent that mean 2=3

Answer:

3.70

Step-by-step explanation:

Answer:

3.70

Step-by-step explanation:

well 26.50-8=18.50

18.50÷5=3.70

so

3.70 should be the price of the 5 books

plz tell me if I'm wrong

The expression for the situation is binomcdf(500, 0.5, 450).

The correct option is B.

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.

Answer:

58.25

Step-by-step explanation:

116.5 / 2

= 58.25

Hope this helps!!

58.25+58.25

Those are the two numbers that add up to that number (116.5)

Btw there are also MULTIPLE numbers that add up to 116.5, I'm just putting the one that makes the most sense.

Answer:

what are you trying to solve?

Answer:

x2=24−4x

Step-by-step explanation:

Answer:

54

Step-by-step explanation:

24÷4 = 6

2+7 = 9 then multiply both together then it gives 54

Answer: The odds of getting tails twice in a row are 1/2 * 1/2 = 1/4. So 25% of the time you'll get heads twice in a row. But, if you've already flipped a coin 99 times, and gotten heads each time, then the odds of your next flip being heads is still just 50:50.

Answer:

smash hit?

Step-by-step explanation:

Answer:

The answer is 9!

Step-by-step explanation:

Ik this is late but for people in the future, the answer is definetly 9.

180 = 6x + 6x + 8x

Now substituting 9 in for the x values;

180 = 6(9) + 6(9) + 8(9)

180 = 54 + 54 + 72

180 = 180

Answer:

x=-5 & y=3

Step-by step explanation:

Answer:

y-intercept= (3,0)

x-intercept=(0,-5)

Step-by-step explanation:

5y-3x=15

5y=3x+15

y=3/5x+3<---3 is the y-intercept

Find the inverse by replacing y with x and x with y

x=3/5y+3

3/5y=x-3

y=5/3x-15/3

-15/3=-5<--- -5 is the x-intercept

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

Answer:

Step-by-step explanation:

length times width = area

so you have 8.5w=93.5

divide 8.5 on both sides to get your answer

w= 11

so your width must be 11 inches

Answer: The answer is -50

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

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

Answer:

The answer would be B- 6s+48=258

Step-by-step explanation:

This is because she earns 6 points each time she goes so it would be 6*s, and she already has 48 points so thats where the +48 comes from

:)

Answer:

6s + 48 = 258

Step-by-step explanation:

I hope this helps!

Answer:

Was B the correct answer?

I thought it was B as well.
