Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + b ( m is the slope and b the y- intercept )
Calculate m using the slope formula
m =
with (x₁, y₁ ) = (0, 3) and (x₂, y₂ ) = (4, 0) ← 2 points on the line
m = =
= -
The y- intercept is where the line crosses the y- axis
The line crosses the y- axis at (0, 3 ) ⇒ b = 3
(b)
y = - x + 3 ← equation of line
Answer:
0.8125
Step-by-step explanation:
In this question, we are tasked with calculating the probability that 3 or less of her kittens were female.
Since each bsex is of likely probability, the probability of a male kitten = probability of a female kitten = 0.5
Now to calculate for 3 or less female kitten we are calcualting P(f) ≤ 3
In each case, we use the Bernoulli approximation
P(f) ≤ 3 =
Where m is the probability of a male kitten and f is the probability of having a female kitten with both values = 0.5
P(f) ≤ 3 =(0.3125) + (0.3125) + (0.15625) + (0.03125) = 0.8125
