The probability that the sum of the two numbers Malik picks is less than 5, given that the first number is odd and less than 5 is 0.0494.

<h3>What is a probability?</h3>

Probability is a way to gauge how likely something is to happen. Many things are difficult to forecast with absolute confidence. Using it, we can only make predictions about how probable an event is to happen, or its chance of happening.

Probability can range from 0 to 1, with 0 denoting an impossibility and 1 denoting a certainty.

Probability of an event P(E) = Number of favourable outcomes/Total number of outcomes.

Calculation for the given condition;

Either 1 or 3 must be present if a given integer is odd and smaller than 5.

The likelihood that it was picked from a set of nine numbers is (2/9).

The probability that the first integer is 1 is 50/50.

If it is and their combined number is less to 5, the second number will either be 1, 2, or 3.

The likelihood that it was picked out of the nine numbers is (3/9).

Additionally, there is a 50/50 probability that the first digit will be 3.

A second number is 1 if it is and the sum would be less than 5.

It was selected with a 1 in 9 chance of being one of the other 8 numbers.

The total probability is;

= (2/9) times [ (0.5 x 3/9) + (0.5 x 1/9) ]

= (2/9) times [ (1.5/9) + (0.5/9) ]

= (2/9) times [ 2/9 ] = 4/81

= 0.0494

Therefore, the probability that the sum of the two numbers malik picks is less than 5 is 0.0494.

sineoko [7]

Answer:

The graph at the bottom left in your group of possible answers.

Step-by-step explanation:

Notice that the original given graph corresponds to the equation:

$y=2x+1$

since the line's slope is 2/1 = 2 and the y-intercept is at the point (0, 1).

So if one modifies the equation multiplying the current slope by 1/2, and the y intercept increased by 3 units, Then the new function would be:

$y=x+4$

A line of slope 1 and y-intercept at (0, 4)

Notice that the graph at the bottom left in your possible answers is representing such function.

Answer:

63 degrees

Step-by-step explanation:

add 4x + 23 and 6x + 7, then equal that to 130. When you find x, plug it into 4x+23 and get 63.

Helpo me if you know the answers

Given:

The nth term of a number sequence is $n^2+2n$ .

To find:

The first 3 terms and the 10th term.

Solution:

We have, nth term of a number sequence.

$a_n=n^2+2n$

For n=1,

$a_1=(1)^2+2(1)$

$a_1=1+2$

$a_1=3$

For n=2,

$a_2=(2)^2+2(2)$

$a_2=4+4$

$a_2=8$

For n=3,

$a_3=(3)^2+2(3)$

$a_3=9+6$

$a_3=15$

For n=10,

$a_{10}=(10)^2+2(10)$

$a_{10}=100+20$

$a_{10}=120$

Therefore, the first three terms are 3, 8 and 15 respectively. The 10th term is 120.
