3x+y=470
x+y = 292
2x = 470-292 = 178
178/2 = x
x= 89
292 - 89 = y
y = 203
adult tickets = 89
student tickets = 203

HELP NEEDED !!!!
Fofino [41]
The answer is Letter D - 84%

68% of the data is within +/- 1 SD from the mean = 59 to 7195% of the data is within +/- 2 SDs from the mean = 53 to 7799.7% of the data is within +/- 3 SDs from the mean = 47 to 83

The whole 68% (59 - 71) scored below 71. Since the data are evenly distributed, we'll get the 32% (100 - 68) outside the range of 68% and divide it by 2 and add the quotient to the original 68% so that we'll get the total data below 71.
   100 - 68 = 32
   32 / 2 = 16
   16 + 68 = 84

Solve the following equations.<br> √3 ⋅ 3^3x = 9
GREYUIT [131]

Answer:

The solution is x = 0.5

Step-by-step explanation:

We need to write everything as a power of 3.

We know that:

\sqrt{a} = a^{0.5}

So

\sqrt{3} = 3^{0.5}

And

9 = 3^{2}

This following property is also important:

\frac{a^{b}}{a^{c}} = a^{b-c}

To solve, the first step is putting everything with the variable x on one side and everything without the variable x on the other side

\sqrt{3}.3^{3x} = 9

3^{0.5}.3^{3x} = 3^{2}

3^{3x} = \frac{3^{2}}{3^{0.5}}

3^{3x} = 3^{2-0.5}

3^{3x} = 3^{1.5}

This means that:

3x = 1.5

x = \frac{1.5}{3}

x = 0.5

It will just keep going on as a decimal so you do not need to keep going, three spaces after the decimal should be an acceptable answer.

What is the slope of the line represented by the equation 2x+3y= –12 ? –32 –23 23 32
mr_godi [17]

Answer:

Option 2 - m=-\frac{2}{3} is the slope of the equation.

Step-by-step explanation:

Given : Equation 2x+3y=-12

To find : What is the slope of the line represented by the equation ?

Solution :

The slope form of line is y=mx+c

Equation 2x+3y=-12

Take 2x to another side,

3y=-12-2x

Divide 3 both side,

y=\frac{-12-2x}{3}

y=\frac{-2}{3}x-4

On comparing with general equation,

m=-\frac{2}{3} is the slope of the equation.

Therefore, option 2 is correct.
