If you are given he has blond hair, so the total probability will be 35%. And among them, he needs to have blue eyes, its probability is 14% among the 35%. So the final probability is 14%/35%=40%.
D. -2, if the lines are parallel then the slope is the same but the y-int is different
Answer:
A. 125 degrees
Step-by-step explanation:
Constant of proportionality is the constant value of the two proportional quantities, in this problem p and s, where 4 is the factor of proportionality because it is constant or k.
In simple terms, p is in direct proportion to s wherein the increase or decrease in value of s results to the increase or decrease in value of p with 4 the only factor remaining unchanged.
In the above problem, the number 4 is derived from the word square. We all know that a square has 4 sides of equal lengths, therefore, the perimeter is equivalent to the product of 4 and its lenght.
1) According to the statement, the Temperature will be modeled with a sine function.
2) a genaral sin function is of the type: <span>Asin(mt + p) + M</span>
where:
t is the variable
A is the amplitud: the fluction fluctuate +/- A units over the mean value. A = 23.5°
M is the mean value. M = 47.5°
m is the frequency, which we need to be 2π/12 (the complete cycle is 12 months) = m = π/6
p is the phase shift, which is 4. p = 4
Then:
a) the model or function is T(t) = 47.5° + 23.5* sin [ (π/6) t + 4]
b) T in march => t = 3
T(3) = 47.5° + 23.5° sin [ (π/6)*3 + 4] = 32.1 °
c) T in august => t = 8
T(8) = 47.5° + 23.5° sin [ (π/6)*8 + 4] = 69.7 °
