Answer:

Answer: 12%

Step-by-step explanation:

To find the probability of picking not only a sphere but one that is blue as well, you need to multiply the probabilities of both events because this would show the probability of getting the second event if the first is gotten:

= Probability of sphere * Probability that sphere is blue

= 40% * 30%

= 12%

Can anyone pls help me in dis
nikklg [1K]

Answer:

10.6 cm to the nearest tenth.

Step-by-step explanation:

If we let one side = x. So as each side of a square are equal, and using Pythagoras we have:

x^2 + x^2 = 15^2

2x^2 = 225

x^2 = 112.5

x = √112.5

x = 10.61.

What is 2 9/10 as a decimal.

Factor trinomial by grouping : 10x^2-9x+2​
Angelina_Jolie [31]

Answer:

(2x - 1)(5x - 2)

Step-by-step explanation:

Consider the factors of the product of the x² term and the constant term which sum to give the coefficient of the x- term, that is

product = 10 × 2 = 20 and sum = - 9

The factors are - 5 and - 4

Split the middle term using these factors

10x² - 5x - 4x + 2 (factor the first/second and third/fourth terms by grouping )

= 5x(2x - 1) - 2(2x - 1) ← factor out (2x - 1)

= (2x - 1)(5x - 2)
