Answer:

m∠x = 65°

m∠y = 81°

m∠z = 34°

Step-by-step explanation:

Since we have 2 transversals and a pair of parallel lines, we can see that at ∠A it equals 65°. If we use the Corresponding Angles Theorem, the m∠A = m∠x. Therefore, x = 65°

To find y, we know that a line is 180°. So, 180 - (65 + 34) = 81°

To find z, we know that all angles in a triangle add up to 180°. So, 180 - (81 + 65) = 34°. Alternatively to find z, we could use Alternate Interior Angles Theorem.

A line contains the points (-7,15) and (10,27) what is the slope of the line as a simplified fraction?

Gwar [14]

Answer:

The slope of line for given points is $\frac{12}{17}$

Step-by-step explanation:

Given points of line as :

A = ( - 7 , 15 ) i, e $x_1$ = - 7 , $x_1$ = 15

B = ( 10 , 27 ) i.e $x_2$ = 10 , $y_2$ = 27

Let The slope of line be m

So , The slope with two points is given as equation

m = $\frac{y_2 - y_1}{x_2 - x_1}$

Or, m = $\frac{27 - 15}{10 + 7}$

Or, m = $\frac{12}{17}$

Hence The slope of line for given points is $\frac{12}{17}$ . Answer

Thirty percent of all telephones of a certain type are submitted for service while under warranty. Of these, 70% can be repaired

Varvara68 [4.7K]

Answer:

$X \sim Binom(n=10, p=0.3)$

And for this case we want to find this probability:

$P(X =2)$

And we can use the probability mass function and we got:

$P(X=2)=(10C2)(0.3)^2 (1-0.3)^{10-2}=0.233$

Step-by-step explanation:

Previous concepts

A Bernoulli trial is "a random experiment with exactly two possible outcomes, "success" and "failure", in which the probability of success is the same every time the experiment is conducted". And this experiment is a particular case of the binomial experiment.

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".

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:

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

Solution to the problem

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

$X \sim Binom(n=10, p=0.3)$

And for this case we want to find this probability:

$P(X =2)$

And we can use the probability mass function and we got:

$P(X=2)=(10C2)(0.3)^2 (1-0.3)^{10-2}=0.233$

What is the answer to 18x-5 < 3(6x-2) ?

Marina86 [1]

Answer:

No solution

Step-by-step explanation:

18x - 5 < 3(6x - 2) Distribute the 3 to (6x - 2)

18x - 5 < 18x - 6

-18x -18x Subtract 18x from both sides

-5 < -6 There is no solution because -5 is not less than -6.
