A bag contains 5 red apples and 4 yellow apples. 4 apples are selected at random. Find the probability of selecting 2 red apples

Oksi-84 [34.3K]

Assuming that the apples are not tossed back into the bag after drawing them.

Total of 9 apples.

1st draw yell, 4/9

2nd draw yell, 3/8

3rd draw red, 5/7

4th draw red, 4/6

$\frac{4}{9} * \frac{3}{8} * \frac{5}{7} * \frac{4}{6} = \frac{240}{3024} \\ \\ = \frac{5}{63}$

Using elimination method

bogdanovich [222]

Answer:

The value of x is 2 and y is (-5)

Step-by-step explanation:

<h3>Given;</h3>

-7x + y = – 19
-2x + 3y = – 19

The value of x and y

<h3>By Using Elimination Method;</h3>

First name the equation

-7x + y = – 19 ...(1)
-2x + 3y = – 19 ...(2)

Now, Multiply equation (1) by 3 we get,

3 × (-7x + y = – 19)

-21x + 3y = – 57

Now, Eliminate

-21x + 3y = – 57

-2x + 3y = – 19

+ – +

-19x = -38

x = -38/-19

x = 2

Now, Put the value of x in equation (2) we get the value of y.

-7x + y = – 19

-7(2) + y = – 19

-14 + y = -19

-14 + 14 + y = -19 + 14

y = -5

Thus, The value of x is (-5) and the value of y is 2.

<h3>For Verification;</h3>

-7x + y = – 19

-7(2) + (-5) = – 19

-14 – 5 = – 19

-19 = -19

-2x + 3y = – 19

-2(2) + 3(-5) = – 19

-4 – 15 = – 19

-19 = -19

Here, L.H.S = R.H.S

Hence Verified!

Elena L [17]

Answer:

A theodolite

Step-by-step explanation:

theodolite is a precision instrument that is used to measure the angle in the horizontal and vertical planes and it is the most commonly used in surveying.

A modern developed theodolite consists of a movable telescope that is mounted within two perpendicular axes called the horizontal axis and the vertical axis. Pointing the telescope on a target object will enable measurement of angle with great precision.
