What is the slope of the line that represents this relationship?

One angle is twice another angle. The sum of the angles is 90 degrees. How many degrees are in each angle. Please explain.

Natali [406]

One angle has 60 degrees, the other angle has 30 degrees.

60 divided by 30 = 2.

and 60 + 30 = 90.

Which of the following angles is not coterminal with the other three?

jekas [21]

9514 1404 393

Answer:

b. 17°

Step-by-step explanation:

All of the angles are 2nd-quadrant angles except 17°, which is a 1st-quadrant angle.

17° is the odd angle

__

When you compute ...

mod(angle, 360), you get 163, 17, 163, 163.

In a list of households, own homes and do not own homes. Five households are randomly selected from these households. Find the p

hichkok12 [17]

Answer:

The probability of success for this case would be:

$p =\frac{9}{15}= 0.6$ representing the proportion of homes that are own homes

Let X the random variable of interest, on this case we now that:

$X \sim Binom(n=15, p=0.6)$

The probability mass function for the Binomial distribution is given as:

$P(X)=(nCx)(p)^x (1-p)^{n-x}$

Where (nCx) means combinatory and it's given by this formula:

$nCx=\frac{n!}{(n-x)! x!}$

And we want this probability:

$P(X=3)$

And uing the probability mass function we got:

$P(X=3)= 15C3 (0.6)^3 (1-0.6)^{15-3}= 0.00165$

Step-by-step explanation:

Adduming the following info: In a list of 15 households, 9 own homes and 6 do not own homes. Five households are randomly selected from these 15 households. Find the probability that the number of households in these 5 own homes is exactly 3.

Round your answer to four decimal places

P (exactly 3)=

Previous concepts

The binomial distribution is a "DISCRETE probability distribution that summarizes the probability that a value will take one of two independent values under a given set of parameters. The assumptions for the binomial distribution are that there is only one outcome for each trial, each trial has the same probability of success, and each trial is mutually exclusive, or independent of each other".
