For every number given put one dot above the number on the number line. Ex. 10 would have one dot above it,
17 would have 3 dots above it. Pretty easy to do. Just count how many numbers of each temperature, then plot them.
Answer:
Step-by-step explanation:
sin(x+y) = sin(x)cos(y) + sin(y)cos(x)
sin(x-y) = sin(x)cos(y) - sin(y)cos(x)
Sin(x+y)sin(x-y) = (sin(x)cos(y) + sin(y)cos(x))(sin(x)cos(y) - sin(y)cos(x))
= sin^2(x)cos^2(y) - sin^2(y)cos^2(x)
= sin^2(x)(1-sin^2(y)) - sin^2(y)(1-sin^2(x))
= sin^2(x) - sin^2(x)sin^2(y) - sin^2(y) + sin^2(x)sin^2(y)
= sin^2(x) - sin^2(y)
So L.H.S=R.H.S
Hence proved

Answer:
A. or 4%
B. or 64%
C. 8 times
Step-by-step explanation:
The county-fair prize wheel has equally spaced sections with the following colors: 1 is golden, 2 are silver, 3 are green, 4 are blue, 6 are red, and 9 are yellow, 25 sections in total.
A. The probability of landing on gold is
or 4% as a percent.
B. If the probability of landing on yellow is 36% (or 0.36 as decimal), then the probability of not landing on yellow is
or 64% as a percent.
C. If the wheel is spun 1 time, the probabilty of landing on silver is
or 8% as a percent.
If the wheel is spun 100 times, the expected number of landing on silver is
