A standard die is rolled 12 times and a 2 comes up 3 times. The experimental probability of rolling a 2 with this die is?

Answers

Answer 1

Answer:

1/4

Step-by-step explanation:

Number of trials = 12

Number of successes = 3

Experimental probability = (Number of successes / total number of trials)

Hence,

Experimental probability of obtaining a 2:

= 3 / 12

= 1/4

Answer:

D

Step-by-step explanation:

Slop formula: m = (y2 - y1)/(x2 - x1)

First coordinate: (-3, -7)

Second coordinate: (9, 1)

m = (1- (-7) ) / (9 - (-3) )

m = (1 + 7) / (9 + 3)

m = (8)/(12)

m = 2/3

Hará que la figura sea más grande porque si es menor que uno, la figura será menor. Por ejemplo, si el factor de escala es la mitad de la cifra, será la mitad más pequeña que la cifra original. Y si el factor de escala es 2, la figura será dos veces más grande que la figura original.

17 and 59

Step-by-step explanation:

90-75=17 first one

180-121=59 second one plz give me brainnessttttt pllzzzz

Hey there!

So the first angle is a complementary angle, meaning that two angles put together will equal 90 degrees. Since we already know that one angle is 75 degrees, all we need to do is 90-75 and we get 15 degrees, which is the value of the missing angle.

The second angle is a supplementary angle, which means two angles equal 180 degrees. Since we know that one angle is 121 degrees, we can take that and subtract is from 180 degrees to get 59 degrees, which is the value of the missing angle.

Remember:

A complementary angle is made of up TWO angles that add up to 90 degrees.

A supplementary angle is made up of TWO angles that add up to 180 degrees.

Answer:

B. y = 3x + 1

Step-by-step explanation:

We can look at the table like a bunch of values, where (x) is what is inserted into the equation, and (y) is what comes out.

Now, simply insert the (x) values into each equation and see if they work out or not.

y = (1/3)(-1) + 1 does not equal -2, meaning this equation is defunct.

y = 3(-1) + 1 = -2; y = 3(0) + 1 = 1. This must be the equation as it works for the (x) values given. You can try the other equations, but a simple look at them is all you need to prove them false.

The exterior angles of any polygon is 360 degrees. There are 8 exterior angles, so you have:

8n = 360

divide both sides by 8

n = 45 degrees

Answer: 45

Step-by-step explanation:

Octagon 8 angles

All exterior angles add up to 360 degrees

d.) 22m, 28m, 51m

Answers

Answer:

the largest angle=<PQR

c.) 16m, 24m, 38m

The largest angle of the triangle is ∠PQR and the measurements of the triangles are 16m, 24m, 38m

What is a Triangle?

A triangle is a three-sided flat figure or polygon with three angles.

A triangle has three vertices, and the internal angles amount to 180°.

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x L x B

For a right angle triangle

From the Pythagoras Theorem ,

if a² + b² = c² , it is a right triangle

if a² + b² < c² , it is an obtuse triangle

if a² + b² > c² , it is an acute triangle

Given data ,

Let the triangle be represented as ΔPQR

Now , the measure of side PQ = 7

The measure of side QR = 8

The measure of side PR = 14

Now , for a triangle , the angle opposite the smallest side of a triangle has the smallest measure.

And , the angle opposite the largest side has the largest measure

So , the angle opposite to the side PR = ∠PQR

Therefore , The triangle's largest angle is ∠PQR

Now , the measure of the sides of the triangles are given and

a + b > c

when a = 16 , b = 24 and c = 38

16 + 24 > 38

40 > 38

Therefore , the measures 16m, 24m, 38m form a triangle

Hence , the triangles are solved
