Answer:

Step-by-step explanation:

you first find out the angles mn and mt.

Since ns and ms are the same, we know ms is 35 degrees.

mt is 50, so we subtract 50 and 35 from 180, which is the degree of m.

so the answer is 95 degrees.

What are the coordinates of the vertex of the parabola represent by the equation y=-5x^2+30x-25

Jobisdone [24]

Answer:

The coordinate of the vertex of the parabola is (h,k) = (3,20)

Step-by-step explanation:

The given equation of the parabola is $y=-5x^2+30x-25$

Now, the General Parabolic Equation is of the form:

$y = a (x-h)^2 + k$ , then the vertex is the point (h, k).

Now, to covert the given equation in the standard form:

$y=-5x^2+30x-25 = -5(x^2 -6x + 5)$

Using the COMPLETE THE SQUARE METHOD,

$-5(x^2 -6x + 5) = -5(x^2 -6x + (3)^2 + 5 - (3)^2)\\\implies -5(((x^2 -6x +(3)^2) + 5 - 9)\\= -5((x-3)^3 -4)\\= -5(x-3)^2 + 20$

or $y = -5(x-3)^2 + 20$

⇒The general formed equation of the given parabola is

$y = -5(x-3)^2 + 20$

Comparing this with general form, we get

h = 3, k = 20

Hence, the coordinate of the vertex of the parabola is (h,k) = (3,20)

Which of the following is equivalent to (Cd) to the fifth power

Rina8888 [55]

Answer:

The 3rd option is correct.

Step-by-step explanation:

This is because of an exponent rule that goes:

(xy)^z = x^z(y^z)

The whole thing gets raised to the power. Therefore only the 3rd one works (ps. if you can mark as brainliest that would be amazing, but if not that's fine)

Natali5045456 [20]

Answer:

(6,2)

Step by Step explanation:

1- Add the two equations so the Xs cancel out

2- find y by dividing 6 from both sides

3- plug in the y value in the place of the y in one of the equations

4- solve the equation to find X

5 - put answer in correct format (x,y)

An inspector samples four PC’s from a steady stream of computers that is known to be 12% nonconforming. What is the probability

yarga [219]

Answer: 0.067

Step-by-step explanation:

Binomial distribution formula :-

$P(X)=^nC_xp^x(1-p)^{n-x}$ , here P(x) is the probability of getting success in x trials , n is total number of trials and p is the probability of getting success in each trial.

Given : n = 4 , p = 12 % = 0.12 and x =2

Then , $P(2)=^4C_2(0.12)^2(1-0.12)^{4-2}$

$\Rightarrow\ P(2)=\dfrac{4!}{2!2!}(0.12)^2(0.88)^2=0.06690816\approx0.067$

∴ The probability of selecting two nonconforming units in the sample = 0.067
