Answer:The height of the building which caste a shadow 20.5 m in length is 17.5 m.

Step-by-step explanation:

Given : At a particular time of a day, a 7 high flagstaff castes a shadow which is 8.2 m long.

To find : What is the height of the building which castes a shadow 20.5 meters in length at the same moment?

Solution :

A 7 high flagstaff castes a shadow which is 8.2 m long.

i.e. Shadow of length 8.2 m = 7 m

The shadow of length 1 m = m

The shadow of length 20.5 m = m

The shadow of length 20.5 m = 17.5 m

Therefore, The height of the building which caste a shadow 20.5 m in length is 17.5 m.

13, 5, 4, 9, 7, 14, 4 The deviations are _____.

fenix001 [56]

Answer:

B."5, -3, -4, 1, -1, 6, -4"

Step-by-step explanation:

We are given that

13,5,4,9,7,14,4

We have to find the deviation.

Mean= $\frac{sum\;of\;data}{total\;number\;of\;data}$

Using the formula

$Mean,\mu=\frac{13+5+4+9+7+14+4}{7}$

$Mean,\mu=\frac{56}{7}=8$

Deviation= $x_i-\mu$

$x_i-\mu$

13 5

5 -3

4 - 4

9 1

7 -1

14 6

4 - 4

Hence, option B is correct.

The value of a and b

Jlenok [28]

Answer:

Both a and b would both equal 45 degrees

Step-by-step explanation:

To find this, we need to note that a and 135 create a straight line. Since a straight line has 180 degrees, we can create an equation to solve for a.

135 + a = 180

a = 45

Now that we know a is equal to 45, we can tell that b is also equal to that amount. This is because two parallel lines cut by a transversal creates the same angle.
