out of 125 children at summer camp 45 signed up for swimming 38 for arts and crafts if a child is randomly selected what is the

anzhelika [568]

P(s) = 45/125 = 0.360
P(A&C) = 38/125 = 0.304
Probability that one is not in Arts and Crafts = 1- P(A&C) = 1-0.304 = 0.696

Therefore,
Probability that the child selected is in swimming when its known they didn't sign for Arts and craft = Probability they signed for swimming * Probability that they didn't sign for Arts and Crafts = 0.360*0.696 = 0.25056

This means that the rate of change is 6.

27 + (6 * y)

y = how many years pass.

Each small square on this scale weighs 1 unit. Each larger square weighs 10 units. The weight of the triangle x is unknown. The

Iteru [2.4K]

The equation to represent the relationship of the weights shown on the scale s $22 + x = 34$

The weights are given as:

$Small\ Square = 1$

$Larger\ Square = 10$

The total weight on one side, where there are 4 small squares and 3 large squares is:

$Total =4\times Small\ Square + 3 \times Larger\ Square$

$Total =4\times 1 + 3 \times 10$

$Total =34$

The total weight on the other side, where there are 2 small squares, 2 large squares and 1 triangle is:

$Total =2\times Small\ Square + 2 \times Larger\ Square + 1\times triangle$

$Total =2\times 1+ 2 \times 10+ 1\times triangle$

$Total =2+ 20+ 1\times triangle$

$Total =22+ 1\times triangle$

$Total =22+ triangle$

The weight of the triangle is x.

So, we have:

$Total =22+ x$

The weights on both sides are equal, because the scale is balanced.

So, we have:

$22 + x = 34$

Hence, the equation is $22 + x = 34$
