Answer:
Approximately
.
Step-by-step explanation:
Convert the angle of this sector to radians:
.
The formula
relates the arc length
of a sector of angle
(in radians) to the radius
of this sector.
In this question, it is given that the arc length of this sector is
. It was found that
radians. Rearrange the equation
to find the radius
of this sector:
.
The perimeter of this sector would be:
.
Answer:
90
Step-by-step explanation:
90÷2= 45
90÷3=30
Answer:
0.066
Step-by-step explanation:
We solve this question using z score formula
z = (x-μ)/σ, where
x is the raw score
μ is the population mean
σ is the population standard deviation
For the question
mean birth weight for boys is 3.27 kg, with a standard deviation of 0.51 kg.
x = 2.5
Hence:
z = 2.5 - 3.27/0.51
z = -1.5098
Probability value from Z-Table:
P(x ≤ 2.5) =P(x < 2.5) = P(x = 2.5) =
=0.065547
Therefore, the proportion of baby boys that are born with a low birth weight is 0.066
W = Shauna wakes up early
M = Shauna is early for her Meeting
P = Shauna gains a promotion
1. M -> P
2. W -> M
3. W
: . P
