The answer is b
hope this helps
Answer:
0.1575
Step-by-step explanation:
Probability of picking a girl is 0.45 and probability of a girl scoring A is 0.35.
Therefore probability of a girl scoring A is 0.45*0.35=0.1575
Answer:
the probability that 0≤x≤1/2 and 1/4≤y≤1/2 is 3/64 (4.68%)
Step-by-step explanation:
assuming that X and Y are independent variables for the probability density function f(x,y) :
f(x,y) = 4*x*y for 0≤x≤1 and 0≤y≤0
f(x,y) = 0 elsewhere
then the probability is calculated through:
P(x,y)= ∫f(x,y) dx dy = ∫4xy dx dy
for 0≤x≤1/2 and 1/4≤y≤1/2 we have
P(0≤x≤1/2,1/4≤y≤1/2 ) = ∫4xy dx dy = ∫4xy dx dy = 4*∫x dx ∫y dx = 4*[((1/2)²/2-0²/2)] *[(1/2)²/2-(1/4)²/2)] = 1 * 1/4 * (1/4-1/16) = 1 * 1/4 * 3/16 = 3/64
then the probability that 0≤x≤1/2 and 1/4≤y≤1/2 is 3/64 (4.68%)
This is so hard I don’t know sorry I just need points
Answer:
A. c (in $) = 110(8) +175
Step-by-step explanation:
$175 is the starting price so in terms of an equation or an equation of a line it is the "b" or y-intercept.
c is the "y" or the depedent variable to solve for.
$110 is the increasing interval that is multiplied by the known variable, "x".
8 is the second variable, "x" but is known.
