Answer:
The median is the middle number in a sorted, ascending or descending, list of numbers and can be more descriptive of that data set than the average. ... If there is an odd amount of numbers, the median value is the number that is in the middle, with the same amount of numbers below and above.
Step-by-step explanation:
Cosine is
which applies to a right triangle. I hope that helps you.
Answer:
200
Step-by-step explanation:
Because you are rounding to the hundreds, you look at the tens place. The tens place is a "1" and 1 is below five, so you round down to 200.
Answer:
y = - 
x - 3
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
Calculate m using the slope formula
m = 
with (x₁, y₁ ) = (0, - 3) and (x₂, y₂ ) = (4, - 4) ← 2 points on the line
m = 
= -
Note the line crosses the y- axis at (0, - 3) ⇒ c = - 3
y = - x - 3 ← equation of line
Answer:
Step-by-step explanation:
We would apply the formula for binomial distribution. It is expressed as
P(x = r) = nCr × q^(n - r) × p^r
Where
n = number of samples
p = probability of success.
q = probability of failure
From the information given,
n = 12
p = 90% = 90/100 = 0.9
q = 1 - p = 1 - 0.9 = 0.1
28) Probability that at least 10 are ripe within 4 days is expressed as
P(x ≥ 10) = P(x = 10) + P(x = 11) + P(x = 12)
P(x = 10) = 12C10 × 0.1^(12 - 10) × 0.9^10 = 0.23
P(x = 11) = 12C11 × 0.1^(12 - 11) × 0.9^11 = 0.38
P(x = 12) = 12C12 × 0.1^(12 - 12) × 0.9^12 = 0.28
P(x ≥ 10) = 0.23 + 0.38 + 0.28 = 0.89
29) Probability that no more than 9 are ripe within 4 days is expressed as
P(x ≤ 9) = 1 - P(x ≥ 10)
P(x ≤ 9) = 1 - 0.89 = 0.11
