Step-by-step explanation:

The mean is the average.  Add up all the points, then divide by the number of points.

(12 + 17 + 11 + 13 + 17 + 15) / 6 = 14⅙

Answer:

14.17

Step-by-step explanation:

12+17+11+13+17+15= 85

85/6=14.17

The 14.17 is rounded from a repeating 6.

The mean is the average, so you find the total and divide by the amount you have.

Start of Questions The admission fee at an amusement park is $5.00 for children and $6.00 for adults. On a certain day, 314 peop
Greeley [361]

Answer:

144 children and 170 adults

Step-by-step explanation:

make 2 equations

make :

the children as the regarded as the variable : x

the adults are the regarded as the variable  : y

<em>5x + 6 y = 1740</em>

<em>x + y = 314</em>

<h3><u>solve this by the method of elimination </u></h3>

5x + 6y = 1740

5(x + y = 314)

= 5x + 5y = 1570

5x + 6y = 1740

5x + 5y = 1570

the 5x is cancelled out

6y - 5y = 1740 - 1570

y = 170

now replace the value of y in the eqaution

5x + 6 (170) = 1740

5x =720

x = 144

hence they were 144 children and 170 adults

Can someone help me please
Anastaziya [24]

The first step to solve this problem is to compute first for the area of the bigger rectangle:

A = LW

A = 12m (10m)

A = 120 m^2

Next step is to find the area of the smaller rectangle:

A = LW

A = 7m (2m)

A = 14 m^2

The last step is to deduct the area of the smaller rectangle to the area of the larger rectangle:

Area of larger rectangle – Area of the smaller rectangle = Area of the shaded region

120 m^2 – 14 m^2 = 106 m^2

Therefore, the area of the shaded region is 106 square meters.

HOW TO DETERMINE SLOPE AND Y-INTERCEPT: Use the instructions below to answer this question.

EQUATION: y=\frac{-3}{4}x-3

-------------------------------------------------

<h2>INSTRUCTIONS:</h2>

FINDING THE Y-INTERCEPT:

Do this simply by finding the number your graph starts at on the Y-Axis (vertical line)! In this case, it's at -3!

FINDING SLOPE:

Remember that slope is rise over run (\frac{rise}{run})

RISE = How far the line goes <em>up </em>and <em>down</em>.

RUN = How far the line goes <em>left </em>or <em>right</em>.

HOW DO I FIND IT? All you have to do is count both rise and run from one point on the line to another! WARNING: The point must hit at a vertex, it cannot be counted if it is in the center of the box, or anywhere that does not touch the edge. I also suggest starting from the <u>Y-Intercept</u> and counting.

GOING LEFT OR DOWN: This is a positive number

GOING RIGHT OR UP: This is a negative number.

(You will see how this applies, below, yayyyy)

CALCULATING OUR NUMERATOR, AKA RISE:

Starting from the y, to get to the next point on the line, you can see we have to go down three. This means our numerator is -3!

CALCULATING OUR DENOMENATOR, AKA RUN:

Starting from where we just stopped, we must continue getting to the next point, and to do that, you can see we have to go to the right four! This means our denomenator is 4!

Since the square root of 13 is something really weird (3.6055 something) and does not have a clear end or repeats, it is irrational. Solve for the number before assuming anything
