Ответ:
P =Probability of making free throw by Bob = 70 % = 0.70
Q=Probability that bob will be not able to make a free throw = 1 - 0.70= 0.30
Probability, that bob makes his third free throw on his fifth shot
= Taking fifth throw as free throw and Remaining 4 throws in which (two are free throw=P) and (2 are not free throw=Q)
=
ways
= 6×Q²× P³
= 6 × (0.30)²×(0.70)³
e(x) = 0.18522 (Approx)
Ответ:
b = 3/4
Step-by-step explanation:
The linear equation has the following general form.
y = a.x + b
where,
y is the dependent variable
a is the slope
x is the independent variable
b is the y-intercept
The slope is 1/4, so
y = 1/4 . x + b
We have the ordered pair (0.2, 4/5). We can find the y-intercept by replacing these values in the previous equation.
y = 1/4 . x + b
4/5 = 1/4 . 0.2 + b
b = 3/4
The final equation is
y = 1/4 . x + 3/4
