Answer:

Step-by-step explanation:

There are 3 data sets given as

I) x 7 8 9 10 11 12 13 Total

Frequ 1 2 1 2 2 0 2

Mean dev|x-10|*f 3 4 1 0 3 0 6 17

II) x 7 8 9 10 11 12 13 Total

Frequ 2 3 0 0 1 1 3

Mean dev|x-10|*f 6 6 0 0 1 2 9 24

III) x 7 8 9 10 11 12 13 Total

Frequ 0 0 4 4 1 0 1

Mean dev|x-10|*f 0 0 4 0 1 0 3 8

Thus we find the middle one Jason has the highest deviation.

1. The ratio of the boy's shadow to height is 4 : 6 or 1 : 1.5.

2. Plug the tree's shadow into the ratio and you have 24 : 24 X 1.5

3. 24 X 1.5 = 36.

A trellis consists of overlapping wooden slats.

mars1129 [50]

The value of x in order for the two slats to be parallel is 6.

The measure of the indicated angle is 42°

What is an angle?

The angle is the measure of how inclined are the two surfaces, or lines with respect to each other.

For the slats to be parallel. both the given angles must be equal

So,

(3x +24)° = 7x°

Solving this expression, we get

7x -3x = 24

4x =24

x = 6°

The measure of the indicated angle is

(3x +24)° = 3x6 +24

(3x +24)° = 18+24

(3x +24)° =42°

and 7x = 7x6 =42°

Thus, the measure of the angle is 42°

raketka [301]

Answer:

Price of a senior citizen ticket is $4 and price of a student ticket is $15 .

Step-by-step explanation:

Let us assume that the price a senior citizen ticket be x .

Let us assume that the price a student citizen ticket be y .

As given

The school that Jack goes to is selling tickets to a choral performance.

On the first day of ticket sales the school sold 9 senior citizen tickets and 8 student tickets for a total of $156.

Equtaions becomes

9x + 8y = 156

As given

The school took in $163 on the second day by selling 7 senior citizen tickets and 9 student tickets.

Equations becomes

7x + 9y = 163

Multipy 9x + 8y = 156 by 9 .

81x + 72y = 1404

Multiply 7x + 9y = 163 by 8 .

56x + 72y = 1304

Subtracted 56x + 72y = 1304 from 81x + 72y = 1404 .

81x - 56x + 72y - 72y = 1404 - 1304

25x = 100

$x = \frac{100}{25}$

x = $ 4

Putting value of x in the 56x + 72y = 1304 .

56 × 4 + 72y = 1304

224 + 72y = 1304

72y = 1304 - 224

72y = 1080

$y = \frac{1080}{72}$

y = $15

Therefore the price of a senior citizen ticket is $4 and price of a student ticket is $15 .
