Converse: False because he can live somewhere else but still belong in Hawaii

Inverse: False because he can live somewhere else but still belong in Hawaii

Contrapositive: True because Honolulu belongs to Hawaii so if he doesn't live in Hawaii he absolutely can't live in Honolulu

The vector v has initial point P(1, 0) and terminal point Q that is on the y-axis and above the initial point. Find the coordina
zloy xaker [14]

Answer:

The terminal point is Q(0,4)

Step-by-step explanation:

We are given the following in the question:

Initial point of vector, P(1,0)

The terminal point Q lies on the y-axis, thus Q have coordinates of the form:

Q(0,y)

The magnitude of the vector is \sqrt{65}

Magnitude is given by:

v = \sqrt{(x_2-x_2)^2+(y_2-y_1)^2}\\\sqrt{65}=\sqrt{(0-1)^2+(y-0)^2}\\\sqrt{65}=\sqrt{1+y^2}\\65 = 1+y^2\\y^2 = 64\\y = \pm 8

But since the terminal point is above the initial point, thus,

y > 0\\\Rightarrow y = 4

Thus, the terminal point is Q(0,4)

A pathologist has been studying the frequency of bacterial colonies within the field of a microscope using samples of throat cul
nata0808 [166]

Answer:

P(0) = 0.055

P(1) = 0.16

P(2) = 0.231

P(3) = 0.224

P(4) = 0.162

P(5 or more) = 0.168

Step-by-step explanation:

In a Poisson distribution, the probability that X represents the number of successes of a random variable is given by the following formula:

P(X = x) = \frac{e^{-\mu}*\mu^{x}}{(x)!}

In which

x is the number of sucesses

e = 2.71828 is the Euler number

\mu is the mean in the given interval.

Here λ = 2.90 is the average number of bacteria colonies per field.

This means that \mu = 2.90

Compute P(r) for r = 0, 1, 2, 3, 4, and 5 or more.

P(0) = \frac{e^{-2.9}*(2.9)^{0}}{(0)!} = 0.055

P(1) = \frac{e^{-2.9}*(2.9)^{1}}{(1)!} = 0.16

P(2) = \frac{e^{-2.9}*(2.9)^{2}}{(2)!} = 0.231

P(3) = \frac{e^{-2.9}*(2.9)^{3}}{(3)!} = 0.224

P(4) = \frac{e^{-2.9}*(2.9)^{4}}{(4)!} = 0.162

5 or more:

This is

P(X \geq 5) - 1 - P(X < 5)

In which:

P(X < 5)  = P(X = 0) + P(X = 1) + P(X = 2) + P(X = 3) + P(X = 4) = 0.055 + 0.16 + 0.231 + 0.224 + 0.162 = 0.832

P(X \geq 5) - 1 - P(X < 5) = 1 - 0.832 = 0.168

So

P(5 or more) = 0.168

Dylan is rollerblading along an 8 mile trail in the forest park she stopped for water after 2.4 miles. After another 3.1 miles,
mr_godi [17]

Add up the amount of miles she actually reached to

2.4 + 3.1 =

5.5 = miles already traveled

And then subtract it from the 8 mile trail

8 - 5.5 =

2.5 miles

About 2.5 or 3 miles (rounded to the tenth or whole number?)
