Answer:
ΔB
Step-by-step explanation:
ΔA's angles are: 58º, 54º, and 68º
68º is found by 180 - (58 + 54)
ΔB's angles are: 54º, 68º, and 58º
58º is found by 180 - (68 + 54)
ΔA and ΔB have the same angles, therefore they are similar triangles
Answers:
a) 0.091
Step-by-step explanation:
We are given the following information in the question:
Mean, μ = 140 minutes
Standard Deviation, σ = 15 minutes
We are given that the distribution of time watching videos is a bell shaped distribution that is a normal distribution.
Formula:
a) P(time is less than 120 minutes)
Calculating the value from the standard normal table we have,
The probability that an 18- to 24-year-old spends less than 120 minutes watching video on his or her smartphone per month is 0.091
