10 friends (6 boys and 4 girls) decided to go to the movies. They only have enough money to buy 7 tickets.
What is the probability that 5 boys and 2 girls get the movie tickets?

Answers

Answer:

0.3

Step-by-step explanation:

The number of ways to choose 5 boys from 6 is ₆C₅.

The number of ways to choose 2 girls from 4 is ₄C₂.

The number of ways to choose 7 people from 10 is ₁₀C₇.

P = ₆C₅ ₄C₂ / ₁₀C₇

= (s - t)(t - s - 1). <----  Factored form.

Answers

Answer:

37

Step-by-step explanation:

The answer must be (a multiple of 2, 3, 4 and 6) + 1, and (a multiple of 5) + 1, because 1 or 2 coins were left over when dividing by 2, 3, 4, 6 or 5.

Let's look at the lowest common multiples of 2, 3, 4, 6:

Prime factorisation:

2 = 2

3 = 3

4 = 2 * 2

6 = 2 * 3

therefore, the lowest common multiple is 2 * 2 * 3 = 12

Let's look at the answers that this would give us (ie multiples of 12):

12 + 1 = 13 <-- this would work, but 11 (ie two less than 13) is not a multiple of 5

12 * 2 + 1 = 25 <-- 23 is not a multiple of 5 either

12 * 3 + 1 = 37 <-- 35 (two less than 37) is a multiple of 5 :)

therefore 37 is our answer since it is one more than a multiple of 12 (ie 36) and two more than a multiple of 5 (ie 35)

a²     b²       c²

12² + 35² = 1369

. Where does the line y = 3x + 5 cross the y-axis?

Answers

Answer: at 5

Step-by-step explanation: the 3 is the slope and the 5 is the y intercept. The y-intercept corresponds to the value of 5 when the x value is equal to 0

Based on what we know about the formula of a straight line, the line above would cross the y-axis at 5.

The formula for a straight line takes the form:

y = mx + c

m = Gradient

c = y-intercept

The line described takes the form of y = 3x + 5.

5 is therefore c in the formula of a straight line so we can infer that it is the point where the y-axis is crossed.

In conclusion, the y-axis is crossed at 5.

will the square roots of perfect squares always be irrational numbers

Answers

Nope

hopefully this helped !!

No, the square roots of perfect squares always do not be irrational numbers.

We need to describe whether the square roots of perfect squares always be irrational numbers.

What are perfect squares?

A perfect square is a positive integer that is obtained by multiplying an integer by itself. In simple words, we can say that perfect squares are numbers that are the products of integers by themselves. Generally, we can express a perfect square as x², where x is an integer and the value of x² is a perfect square.

Irrational numbers are the set of real numbers that cannot be expressed in the form of a fraction, p/q where p and q are integers. The denominator q is not equal to zero (q ≠ 0).

So, the square roots of perfect squares are rational numbers and can be placed on a number line. The square roots of non-perfect squares are irrational numbers.

No, the square roots of perfect squares always do not be irrational numbers.

Elmer works in a computer store. He is paid a weekly salary $180 and a commission of 4.5% of all sales. One week, he sold $9770 worth of merchandise. How much did Elmer earn that week?

Answers

Answer:

$619.65

Step-by-step explanation:

We know that he gets paid 180 a week, but we don't know how much he got from the commission of his sales. To find it, you multiply 9770 by 0.045 (because 0.045 = 4.5%) which you get 439.65. You then add the 180 to get 619.65.

9770 * 0.045 = $439.65

$439.65 + $180 = $619.65

Elmer earned $619.65 in that week.
