Answer:
x = 25
Step-by-step explanation:
the line QC is parallel to BR
Then
x/15 = 40/24
Then
24x = 40×15
Then
24x = 600
Then
x = 600/24
Then
x = 25
Answer: what's the question here?
Step-by-step explanation:
Answer:
(0, 3)
Step-by-step explanation:
The y-intercept is point on the y-axis that the line passes through.
You can see the line passes through 3 on the y-axis.
On the y-axis, every point has a 0 for the x-coordinate.
The ordered pair for the point that is 3 on the y-axis is (0, 3).
Answer:
a)0.5611
b)0.1828
c)0.6217
d)0.4389
e)6.25
Step-by-step explanation:
Let's define the following event :
X : ''Calls involving a fax message''
The random variable X can be modeled as a Binomial random variable.
N ~ Bi(n,p)
N ~ Bi(25,0.25)
Where n is the sample and p is the success probability
Let's also define nCr as the combinatorial number :
The probability function for X is :
Where k is the number of success
a)
b)
c)
d)
e) They are asking us about the expected value for random variable X
In a Binomial random variable :
E(X) = μ = n.p
Answer:
20 miles
Step-by-step explanation:
We apply trigonometry and using the attached illustration, we know that sine of an angle is the ratio of opposite to hypotenuse. In this case, the hypotenuse is the diagonal in question.
Sin 30°=10/hypotenuse
Hypotenuse=10/sin30°=10/0.5=20 miles
Therefore, the plane has gone a diagonal distance equivalent to 20 miles from its take off position
