Answer:

d = 65°

w = 55°

Step-by-step explanation:

m∠DAC +∠m∠CAB = 60

m∠DAC + 35 = 60

m∠DAC = 25

m∠DAC + d = 90

25 + d = 90

d = 65°

m∠GAF + w + d = 180

60 + w + 65 = 180

w + 125 = 180

w = 55°

The average number of newspapers for sale in an airport stand is 15. SD is 6. The average age of the pilots is 36 and SD is 4. W
balu736 [363]

Answer:

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.

Step-by-step explanation:

The coefficient of variation is used to measure consistency of a data set. It is the standard deviation divided by the mean. The higher the coefficient of variation, the more variable, that is, the least consistent the data set is.

The average number of newspapers for sale in an airport stand is 15. SD is 6.

The consistency is:

C = \frac{6}{15} = 0.4

The average age of the pilots is 36 and SD is 4.

The consistency is:

C = \frac{4}{36} = 0.11

The average age of pilots has a lower coefficient of variation, so it is the most consistent data set.

Can some one please help me find the solution of the question
creativ13 [48]

Answer:

x=16°

Step-by-step explanation:

tanθ=opposite/adjacent

tan(<CAB)=BC/AB

<CAB=tan⁻¹(21/29)=35.9097308°

tanθ=opposite/adjacent

tan(<DAB)=BD/AB

<DAB=tan⁻¹((21/2)/29)=19.90374954°

<CAB=<DAB+x

x=<CAB-<DAB

=35.9097308-19.90374954

x=16.00598126°

144kg in the ratio of 9:8:7​
ANEK [815]

Step-by-step explanation:

Hey there!

Given;

Ratio = 9:8:7

Let "x" be the common factor. So,

9x+8x+7x = 144

or, 24x = 144

or, x = 144/24

or, x= 6

It's like;

= 9*6:8*6:7*6

= 54:48:42

Therefore, their ratio is 54:48:42.
