Answer:
5
Step-by-step explanation:
square root is 49 is 7
so
1 side is 7
so
original side is 7 - 2
which is
5
Answer:
The original side length was 5 in.
Step-by-step explanation:
Area of new square is (side length)^2. Here,
that area is (x + 2)^2 = 49 in^2, and we must find x.
Taking the square root of both sides, we get:
x + 2 = +√49 = +7
Subtracting 2 from both sides yields x = -2 + 7 or x = 5
Check: does (5 + 2)^2 = 49? YES

Jamal's friends toss 12 balls to him at the same time. Three balls are red, 3 are green, 3 are blue, and 3 are white. Jamal manages to catch 5 of the balls.
What is the probability that he catches 2 red balls and 1 ball of each of the other colors?
Answer:
81/792 or 9/88 or 10.2%
Step-by-step explanation:
Possibility: nCr(12,5) = 792
Red: nCr(3,2) = 3
Blue, Green, White: nCr(3,1) = 3
3 * 3 * 3 * 3 = 81
81/792 simplified is 9/88 percentage is 10.22%
The probability that Jamal will catch 2 red balls and 1 ball of each of the other colors is 0.1025.
What is probability?Probability is the branch of Mathematics that deals with the measurement of the chance of occurrence of a random event.
The probability of any event always lies in the close interval of 0 and 1 [0,1].
The zero value of probability indicates that the event will not happen while its value equal to one indicate that it will happen.
The total numbers of balls are 12.
Each color has 3 balls.
If total 12 balls are tossed, the number of ways of catching 5 of them is,
¹²C₅ = 792
The number of ways of catching 2 red balls out of 3 is ³C₂ = 3
The number of ways of catching 1 green ball out of 3 is ³C₁ = 3
The number of ways of catching 1 blue ball out of 3 is ³C₁ = 3
The number of ways of catching 1 white ball out of 3 is ³C₁ = 3
Thus, the probability as per the question is given as follows,
(3 × 3 × 3 × 3)/792
= 81/792
= 0.1025
Hence, the probability of catching 2 red balls and 1 ball of each of the other colors is 0.1025.

What which is equivalent to√x10?
Answer:
E) x^5
Step-by-step explanation:
example, [tex]\sqrt{3}[/tex] = 3^1/2 where '1' is the coefficient of 3
[tex]\sqrt{3}[/tex] is the same as [tex]\sqrt[2]{3}[/tex] (it's assumed to be 2 unless another number is there)
so, √x^10 is the same as x^(10/2) which is x^5

Answer:
Tim read 81 pages.
Step-by-step explanation:
If he read 3 pages on Monday and tripled the amount of pages he red based of off the amount of pages he read the previous day, he would have read 3 pages on Monday, 9 pages on Tuesday, 27 pages on Wednesday, and 81 pages on Thursday.
Monday: 3
Tuesday: 3 x 3 = 9
Wednesday: 9 x 3 = 27
Thursday: 27 x 3 = 81

A group of 20 people are going to run a race. The top three runners earn gold, silver, and bronze medals. How many outcomes are possible for these awards?
Answer:
There are 6,840 possible outcomes for these awards.
Step-by-step explanation:
Given that a group of 20 people are going to run a race, and the top three runners earn gold, silver, and bronze medals, to determine how many outcomes are possible for these awards, the following calculation must be performed:
20 x 19 x 18 = X
380 x 18 = X
6.840 = X
Therefore, there are 6,840 possible outcomes for these awards.
Total outcomes that are possible for these awards are 6840 outcomes, calculated using permutation.
Total number of people=20
what is the difference between permutation and combination?permutation means the arrangement of items while the combination is all about the selection of some out of many.
let us say start with the gold medal
no of ways a gold medal can be given = ²⁰C₁ = 20
Now, the number of people left is 19
no of ways a silver medal can be given = ¹⁹C₁ = 19
Now, the number of people left is 18
no of ways a bronze medal can be given = ¹⁸C₁ = 18
possibility of total outcomes=20*19*18 = 6840ways
Therefore, total outcomes that are possible for these awards=6840

Answer:
No
