A woman bought 210 oranges for $6.50. She sold all of them at 3 for 20cents. How much profit did she make?

Dafna11 [192]

Divide total bought by 3 and multiply by 20cents:

210/3 = 70

70 x 0.20 = $14.00

Subtract the amount they paid by the amount they made:

14.00 - 6.50 = $7.50

The profit made was: $7.50

A baseball player has a batting average of 0.260. Suppose that you observe successive at-bats of the player and note for each at

Georgia [21]

Answer: Our required probability is 0.278.

Step-by-step explanation:

Since we have given that

Probability that a player has a batting average = 0.260

Probability of success = 0.260

Probability of failure = 1-0.260 = 0.74

Number of times at bat = 4

Probability that the player will get two or more hits in his next four times at bat is given by

$P(X\geq 2)=P(X=2)+P(X=3)+P(X=4)\\\\P(X\geq 2)=^4C_2(0.26)^2(0.74)^2+^4C_3(0.26)^3(0.74+^4C_4(0.26)^4\\\\P(X\geq 2)=0.278$

Hence, our required probability is 0.278.

How do you explain a rational number or a ratio?

allochka39001 [22]

Any number that can be rewritten as a simple fraction is a rational number. This means that natural numbers, whole numbers and integers, like 5, are all part of the set of rational numbers as well because they can be written as fractions, as are mixed numbers like 1 ½.
