There are less than 200 apples in a box. it is known that 2, 3, 4, 5, or 6 kids can share these apples evenly. how many apples c
MArishka [77]
Hi!

200 ÷ 2 = 50

200 ÷ 3 = 66.6 repeat.

200 ÷ 4 = 50

200 ÷ 5 = 40

200 ÷ 6 = 33.3 repeat.

So, there can be either 50 or 40 apples in that box.

You toss 3 coins what is the probability that you get exactly 2 heads given that you get at least one tail
forsale [732]
Seeing as there are three coins, which means there are 3 heads and 3 tails.There's only a 50% chance it'll land on either side one one coin. I believe the chances to get two heads, and one tail would be somewhere around 80%, since there are only 8 possible outcomes.

40. Resuelve la siguiente operación.
Naddik [55]

Option B is correct. The required expression on expansion of 20х-[2х -(х+2)-(6-x 2 )-(28 +x+x2]  is 20x + 36

Expressions are function that does not include "equal" sign

Given the expression

20х-[2х -(х+2)-(6-x² )-(28 +x+x2]

Expand and collect the like terms

= 20х-[2х -х-2-6+x² -28 - x - x²]

= 20x - [x - 8 + x²  - 28 - x - x² ]

x and x² cancels out from the expression to have

= 20x - [- 8 - 28]

= 20x -(-36)

= 20x + 36

Hence the required expression on expansion is 20x + 36
