Answer:415
Step-by-step explanation:
Angle DBE + Angle CBE = 90°
(0.1x-22)° + (0.3x-54)° = 90°
(0.4x - 76)° = 90°
(0.4x)° = 166°
x= 1660/4 = 415
(0.1 415 - 22)° + (0.3 415-54)° = 90°
41.5 - 22 + 124.5 - 54 = 90
166 - 76 = 90
Answer:
Step-by-step explanation:
Assuming a normal distribution for the amount spent by Canadian households for high-speed broadband access, the formula for normal distribution is expressed as
z = (x - u)/s
Where
x = amount spent by the Canadian households.
u = mean amount spent monthly.
s = standard deviation
From the information given,
u = $80.63 CDN
s = $27.32 CDN
We want to find the probability that the average amount will exceed $85. It is expressed as
P(x greater than 85) = 1 - P(x lesser than or equal to 85)
For x = 85
z = (85 - 80)/27.32 = 0.18
Looking at the normal distribution table, the corresponding z score is 0.57142
P(x greater than 85) = 1 - 0.57142 = 0.43

16 is the answer. All 3 numbers can be divided by 16 at most. It can’t be 16a because 48b does not have a. It can’t be 16b because 32a does not have b.
