So cos θ = 5/sqrt(26)
adjacent = 5
hypotenuse = sqrt 26
by pythagoras opposite = 1
so sin θ = 1/sqrt (26)
and tan θ = 1/5
Let the probability of giving birth to a girl is .
The number of girls X in a family with 6 children follows binomial distribution.
The probability mass function of binomial random variable X is
.
Here
The required probability is
To find surface area, we can use the equation:
SA=2lw+2wh+2lh, where:
l=10 in
w=3 in
h=7 in
SA=(2)(10)(3)+(2)(3)(7)+(2)(10)(7)
SA=60+42+140
SA=242 in²
Answer:
The answer is "Approximately normal".
Step-by-step explanation:
sample size
Sample size
It is because the sampling distribution of the sample means is approximately normal.
$2.40/34= 0.070588235294118 is the answer I believe
