The school sold 200 tickets to play. Student tickets are $4 and adult tickets are $6. If they made a total $930 how many of each

motikmotik

Answer:

65 adult tickets and 135 student tickets were sold.

Step-by-step explanation:

4s + 6a = 930

s + a = 200

s = -a + 200

4(-a + 200) + 6a = 930

-4a + 800 + 6a = 930

2a + 800 = 930

2a = 130

a = 65

There were 65 adult tickets sold.

200 - 65 = 135

There were 135 student tickets sold.

Check:

4(135) + 6(65) = 930

540 + 390 = 930

930 = 930

Find the mean,median,mode and,range of the following data set 18 12 14 12 16 24 18 12 14

devlian [24]

Answer:

Mean = 15.5

Median = 14

Mode = 12

Range = 12

Step-by-step explanation:

The mean is the sum of all the values divided by the number of values.

So mean = S/N.

There are 9 values, so N = 9.

These values are 18,12,14,12,16, 24,18,12,14. So S = 18+12+14+12+16+24+18+12+14 = 140

Mean = 140/9 = 15.5

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

For the median, the first step is to sort all the elements in a crescent way.

So 12 12 12 14 14 16 18 18 24

Then you will need to consider whether N is even or odd.

If N is even, to find the median you need to sum the values at the positions N/2 and (N/2)+1 and divide by 2.

In this case, N is odd. So the median will be the value at the position (N+1)/2, which is 14.

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

The mode is the value that appears most often in a set. In this set, 12 appears 3 times, 14 and 18 appears twice and while 12 and 13 appear once each. So the mode is 12.

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

The range of a set is:

Highest value - Smallest Value

In this set: range = 24-12 = 12

Simplify -1/64........

Anettt [7]

Answer:

- 2⁻⁶

Step-by-step explanation:

To simplify this we have to know the following rules.

(i) (xᵃ)ᵇ = xᵃᵇ

(ii) 1/xᵃ = x⁻ᵃ

Given: $\frac{-1}{64}$

= $\frac{-1}{4^3}$

= $\frac{-1}{(2^2)^3}$

= $\frac{-1}{2^6} \hspace{10mm}$ [using (i)]

= $2^{-6}$ [using (ii)]

Hence, the simplified form would be: $2^{-6}$

What is the seventh term of the geometric sequence with a first term of 729 and a common ratio of ?

SVEN [57.7K]

<u>Given</u>:

Given that the first term of the geometric sequence is 729.

The common ratio is $\frac{1}{3}$

We need to determine the seventh term of the sequence.

<u>Seventh term</u>:

The seventh term of the sequence can be determined using the formula,

$a_n=a_1(r)^{n-1}$

To find the seventh term, let us substitute n = 7 in the above formula, we get;

$a_7=a_1(r)^{6}$

Now, substituting $a_1= 729$ and $r=\frac{1}{3}$ , we get;

$a_7=729(\frac{1}{3})^{6}$

$a_7=729(\frac{1}{729})$

$a_7=1$

Thus, the seventh term of the geometric sequence is 1.
