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?
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
P = 6 × 6 / 120
P = 0.3

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

A box has a volume of 456 cubic inches, with a length of 1 foot and a height of 4 inches. Determine the width of the box.
Answer:
114
Step-by-step explanation:
1 x 4 x 114 = 456
Answer:
Width: 9.5 inches
Step-by-step explanation:
We have to convert the 1 foot to 12 inches.
New Dimensions: 12in x 4in x ?in
We multiply the 12 by 4 and we get 48.
Now we divide 456 by 48.
We get: 9.5
9.5in is the width of the box.
Write the equation of a line in the given form.
The line through (4,-4) and (0,-5) in SLOPE INTERCEPT form
Answer:
[tex]y = \frac{1}{4}x - 5[/tex]
Step-by-step explanation:
Slope intercept form: y = mx + b
Find slope:
m = (y₂ - y₁) / (x₂ - x₁)
= (-5 - (-4)) / (0 - 4)
= -1 / -4
= 1/4
Find y intercept using anyone of the given points and slope from above:
y = mx + b
[tex]-5 = \frac{1}{4}(0) + b[/tex]
b = -5
Now use the above slope and y intercept to create equation of a line:
[tex]y = \frac{1}{4}x - 5[/tex]
X-7y=10 and 2x+14y=21 is it parallel, perpendicular or neither and why

The equations are not parallel because the slopes of the two lines are not equal.
will the square roots of perfect squares always be irrational numbers
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.
