The table shows whether members in a fishing group caught fish or did not catch fish and whether they fished from a boat or from
MariettaO [177]
The given scenario falls under the category of conditional probability. There are a total of 56 people in the fishing group described above. The probability that the a person caught a fish and fished from a boat is 24/56. The probability that he fished from a boat is (24+11)/56. For the conditional probability in this item is,
                                 P = (24/56) / ((24+11)/56) = 24/35 = 0.69

Explain (in words) what you would do to find the missing value in the equation. You do not find the missing number! Equation: ?
maks197457 [2]

Answer:

The missing value = 23\frac{1}{24}

Step-by-step explanation:

Given - Equation: ? + 59 5/8= 82 2/3

To find - Explain (in words) what you would do to find the missing value in

              the equation. You do not find the missing number.

Proof -

Let the missing number = x

So, the equation becomes x + 59\frac{5}{8} = 82\frac{2}{3}

⇒x = 82\frac{2}{3} - 59\frac{5}{8}

     = \frac{248}{3} - \frac{477}{8}

     = \frac{1984 - 1431}{24}

     = \frac{553}{24}

     = 23\frac{1}{24}

⇒x = 23\frac{1}{24}

∴ we get

The missing value = 23\frac{1}{24}

Explanation -

Here we have given the ? with addition of number that is equation to some number.

We just have to subtract the two numbers to find the missing value , as we do above.

Hillary is making a blanket for her mom. Three fourths of the blanket is green and the rest is yellow. Two thirds of the yellow
Leviafan [203]

Answer:

1/6

Step-by-step explanation:

Hillary is making a blanket for her mom.

Let the total blanket = 1

Three-fourths of the blanket is green and the rest is yellow.

The fraction for the rest(yellow portion) = 1 - 3/4

The Lowest Common Denominator is 4

Hence,

4 - 3 /4 = 1/4

Two-thirds of the yellow part has her name on it.

The fraction of the blanket that will have her name on it is calculated as

2/3 of 1 /4

= 2/3 × 1/4

= 1/6
