List the sides of each triangle from shortest to greatest

Lelechka [254]

In every triangle, the largest side, is opposite the largest angle.

Also, the smallest side, is opposite the smallest angle.

a. $70^o\ \textgreater \ 60^o\ \textgreater \ 50^o$ so $|RQ|\ \textgreater \ |PR|\ \textgreater \ |PQ|$ ,

because RQ is opposite angle P, the largest,
PR is opposite angle Q , the middle
and PQ is opposite angle R, the smallest.

Greatest side: RQ

b. The sum of the measures of the interior angles of any triangle is 180°,

so

$m(A)+m(B)+m(C)=180^o\\\\50^o+45^o+x=180^o\\\\x=180^o-50^o-45^o=85^o$

thus, m(C) is the largest angle. This means the largest side is the side AB.

Answers:

a) RQ
b)AB

A number is equal to twice a smaller number plus 3. Yhe same number is equal to twice the sum of smaller number and 1. How many

allsm [11]

Answer:

There is no solution to the problem

Step-by-step explanation:

In order to find the solutions to the problem you can write the situation in an algebraic form.

You have that a number is equal to twice a smaller number plus 3. This can be written as follow:

$x=2y+3$ (1)

where x is the number and y is the smaller number

Furthermore, the same number x is equal to twice the sum of the smaller number and 1, which can be written as follow:

$x=2(y+1)$ (2)

To find the solution you equal the equation (1) with (2), and you solve for y:

$2y+3=2y+1$

$3=1$

You obtain an inconsistency, hence, the situation of the problem does not have solution

The average rate of job submissions in a busy computer center is 3 per minute. If it can be assumed that the number of submissio

san4es73 [151]

The probability that at least 40 jobs will be submitted in 15 minutes is <u>0.79162</u>.

The number of jobs submitted per minute follows Poisson Distribution.

A Poisson Distribution over a variable X, having a mean λ, has a probability for a random variable x as $P(X= x) = e^{-\lambda} \frac{\lambda^{x} }{x!}$ .

In the question, we have the random variable x = 40.

The mean λ = Average jobs per minute*time = 3*15 = 45.

We are to find the probability that at least 40 jobs will be submitted in 15 minutes, which is represented as P(X ≥ 40) = P(X > 39).

P(X > 39) = 1 - P(X ≤ 39) = 1 - poissoncdf(45,39)

As to find the probability of a Poisson Distribution P(X ≤ x), for a mean = λ, we use the calculator function poissoncdf(λ,x).

Therefore, P(X > 39) = 1 - 0.20838 = 0.79162.

Therefore, the probability that at least 40 jobs will be submitted in 15 minutes is <u>0.79162</u>.

I give brainlilstttttt

Roman55 [17]

Answer:

the answer is A. 36

Step-by-step explanation:

because the rectangles are proportionate, I set up ratios.

90:75 so h:30

from there I did 70/30 because those sides are proportionate to each other and this got me 2.5. then I did 90/2.5 to get 36

The problem is about functions and i think its only 2 possible answers

liubo4ka [24]

Your answer would be C and D, the domain for this function is all real numbers, and the range for this function is the set {-5}.

C is correct: The domain of a function is the amount of x values. For example, if you had a line going from an x value of 1 to an x value of 3, the domain would be {1<x<3}.

In this case, C is stating the domain of this function is all real numbers. This is true, because the straight line will continue for all values of x, so therefore the domain is all values of x, or all real numbers.

D is correct: The range is the exact opposite of a domain of a function. It is the number of y values the function covers.

In this case, D is stating the range is {-5}. This is correct, because the straight line only covers the y value of -5, so therefore that is the range.

A is therefore incorrect because the domain has already been established as all real numbers. B is incorrect because a horizontal line is a function, and one value of y can have multiple values of x. E is incorrect because the range has already been established as only one number.

Good luck!
