Answer:

The coordinates of Y' will be:  A'(4, -3)

Step-by-step explanation:

Triangle XYZ with vertices

We have to determine the answer for the image Y' of the point Y(-3, 4) with respect to the line mirror y=x.

We know that when P(x, y) is reflected in y = x, we get P'(y, x)

i.e.

The rule of y=x:

As we are given that Y(-3, 4), so the coordinates of Y' will be:

A(-3, 4) → A'(4, -3)

Therefore, the coordinates of Y' will be:  A'(4, -3)

Answer:

Ok? Did you finished asking the question? Just in case, that is 89/100 or 0.89

Step-by-step explanation:

Here, Population: All parents, Sample: 100 parents and Parameter: Parents’ approval of teachers

The sample space of a random experiment is the collection of all possible outcomes. An event associated with a random experiment is a subset of the sample space. The probability of any outcome is a number between 0 and 1. The probabilities of all the outcomes add up to 1.

Given that, A local school board wants to get parents to evaluate teachers. They select 100 parents and find that 89% approve of their child’s teacher, here we need to find the population, sample and parameter of interest

So, as we see,

The population is the entire group that you want to draw conclusions about.

Therefore, the population here is = All parents

The sample is the specific group that you will collect data from.

Therefore, the sample = 100

The parameter is any characteristic that can help in defining or classifying a particular system.

Therefore, the parameter = Parents’ approval of teachers

Hence, we get Population: All parents, Sample: 100 parents and Parameter: Parents’ approval of teachers

Answer:

10

Step-by-step explanation:

Using Euler's formula for polyhedra

F + V - E = 2

Here V = 16 and E = 24, thus

F + 16 - 24 = 2, that is

F - 8 = 2 ( add 8 to both sides )

F = 10

Answer:

52 units.

Step-by-step explanation:

Use the Triple 5-12-13

20 / 4 = 5

48/ 4 = 12

So  the hypotenuse = 4 * 13 = 52.

The lengths of Hypotenuse 52 units.

The Pythagoras theorem states that the square of a triangle's hypotenuse is equal to the sum of its other two sides' squares.

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

Given:

The measurement of two sides are 20 units and 48 units.

Now, Using Pythagoras theorem

H² = P² + B²

H² = 20² + 48²

H² = 400 + 2304

H² = 2704

H = 52 units.

Hence, lengths of Hypotenuse 52 units.

Answer:

D

Step-by-step explanation:

We need the numbers of each before we can calculate the probability

Number of even numbers are 50

Number of odd numbers are 50

Number of perfect squares;

1 , 4 , 9 , 16 , 25 , 36 , 49 , 64 , 81 and 100

10 perfect squares

Probability of selecting even = probability of selecting odd = 50/100 = 1/2

Probability of selecting a perfect square = 10/100 = 1/10

Thus, the probability of having the draws in the other stated in the question will be;

1/2 * 1/2 * 1/10 = 1/40

Step-by-step explanation:

x = ky², where k is a real constant.

When x = 3, y = 3.

Represent Tristan's house with T, his grandparent's with G and his parents with P.

Such that:

[tex]TP = 6[/tex]

[tex]GP = 6.4[/tex]

Required

Find TG

To solve this, we make use of Pythagoras Theorem which is represented as:

[tex]GP^2 = TP^2 + TG^2[/tex]

Substitute values for GP and TP

[tex]6.4^2 = 6^2 + TG^2[/tex]

[tex]40.96 = 36 + TG^2[/tex]

Collect Like Terms

[tex]TG^2 = 40.96 - 36[/tex]

[tex]TG^2 = 4.96[/tex]

[tex]TG = \sqrt{4.96[/tex]

[tex]TG = 2.2[/tex] --- Approximated

Answer:

A = 51°   b = 15.3858...   c = 24.448

Step-by-step explanation:

Given: B= 39°

a = 19

and that it's a right triangle

so that means the other 3rd angle is

A+39+90=180

A= 51°

use SOH CAH TOA to remember how sin cos and tan fit on the triangle

Sin(x)=Opp/Hyp    Cos(x)=Adj/Hyp  Tan(x)=Opp/Adj

Let's use  Tan to find b

Tan(b) = Opp / Adj

Tan(39) = b / 19

19*Tan(39) = b

15.38589... = b

use Pythagoras to find c

c = [tex]\sqrt{a^{2} +b^{2} }[/tex]

c = [tex]\sqrt{19^{2} +15.3858^{2} }[/tex]

c = 24.448....
