It's D, 15!/(15 - 5)! .
15! is the number of ways of permuting 15 objects. In other words, if you have 15 open positions,
_ _ _ _ _ _ _ _ _ _ _ _ _ _ _
from the 15 total objects you can pick, there are 15 choices for the first position, 14 for the second, 13 for the third, and so on, so that there is a total of
15 * 14 * 13 * … * 2 * 1 = 15!
possible arrangements.
But you're taking 5 objects at a time, so we only have 5 positions to fill:
_ _ _ _ _
and there are 15 choices for the first position, 14 for the second, 13 for the third, 12 for the fourth, and 11 for the fifth, so the total number of arrangements is
15 * 14 * 13 * 12 * 11 = 15!/10! = 15!/(15 - 5)!

Britney's Cafe offers two kinds of espresso: single-shot and double-shot. Yesterday afternoon, the cafe sold 2 single-shot espressos and 18 double-shot espressos. What percentage of the espressos sold were single-shot?
Answer:
10% of espressos sold are single shot espressos.
Step-by-step explanation:
Single shot espressos, as percentage of total espressos sold =
[ Single espressos / Total ( ie Single + Double shot) ] x 100
[ 2 / (2 + 18) ] x 100
(2 / 20) x 100
= 10%
Santiago is trying to earn experience points in his newest game. He knows that finding
gophers will get him the most points. His number of experience points after his first attempt
can be represented by the linear equation - 24x + 2y = 900, where y represents Santiago's
total number of experience points and x represents the number of gophers he finds.
What is the slope of the line? What does this represent?
F The slope is 12; he earns 1 point for every 12 gophers he finds.
G The slope is 450; he earns 1 point for every 450 gophers he finds..
# The slope is 12; he earns 12 points for each gopher he finds.

A classmate buys and resells scooters. If they original buy a scooter for $45.85 and mark it up 90%. What is the new selling price?
Answer:
$87.12
Step-by-step explanation:
To mark up the price you are basically doing 45.85×190%.
If you take a percentage and make it a normal number you need to divide by 100.
190÷100= 1.9
So you multiply 45.85×1.9=87.115
Because this is money you cant have $87 and 11 and a half cents. So you need to round
You need to round up because it is 5, which means that you get $87.12

At an intersection, the red light times are normally distributed
with a mean time of 3 minutes and a standard deviation of 0.25
minutes. Approximately what percent of red lights last between
2.5 and 3.5 minutes? (2 points)
32%
68%
Answer: The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.
Step-by-step explanation:
Given: Mean time = 3 minutes
standard deviation = 0.25 minutes
The probability of red lights last between 2.5 and 3.5 minutes :-
[tex]P(2.5<x<3.5)\\\\=P(\dfrac{2.5-3}{0.25}<\dfrac{x-\mu}{\sigma}<\dfrac{3.5-3}{0.25})\\\\=P(-2<z<2)\\\\=2P(Z<2)-1\\\\=2(0.9772)-1\\\\=0.9544[/tex]
The percent of red lights last between 2.5 and 3.5 minutes = 95.44% approx.

If you flip a coin 7 times what is the probability that you will get exactly 2 tails
Answer:
The answer is 2/7.
Step-by-step explanation:
If you flip a coin 7 times then 7 is the denominator, which stands for the total amount of times you flipped the coin. The numerator is 2, which is the amount of times you land on the same thing, in this case, landing on tails.

Yes or no????????????
Answer:
Yes
Step-by-step explanation:
If a triangle follows the Pythagorean theorem, then it is right. The Pythagorean theorem states the following,
[tex]a^2 + b^2 = c^2[/tex]
Where (a) and (b) are the legs or sides adjacent to the right angle of the right triangle, and (c) is the hypotenuse, side opposite the right angle, the longest side.
Substitute in the given values and solve,
[tex](6)^2 + (8)^2 = (10)^2\\\\36 + 64 = 100\\\\100 = 100[/tex]
The given side lengths form a right triangle.

If the given ΔXYZ is rotated by 180 degrees around point X in a clockwise direction, what are the new coordinates of the Y and Z vertices? Select the two correct answers.
Answer:
Options C and D
Step-by-step explanation:
From the graph attached,
Coordinates of the vertices,
X → (0, 0)
Y → (-1, -2)
Z → (0, -2)
Rule for the rotation of a point (h, k) by 180° about the origin is given by,
(h, k) → (-h, -k)
By this rule,
Coordinates of the image points will be,
X(0, 0) → X'(0, 0)
Y(-1, -2) → Y'(1, 2)
Z(0, -2) → Z'(0, 2)
Therefore, Option (C) and Option (D) are the correct options.

C/D

In the equation: (16)^3=2^3/2x how could you solve for x?
Answer:
x = 8
Step-by-step explanation:
16 is the same as 2^4
(2^4)³ = 2^3/2x
2^12 = 2^3/2x
as long as bases are both the same then set exponents equal
12 = [tex]\frac{3}{2}[/tex]x
3x = 24
x = 8

50 Benson purchased a $1,800 certificate of deposit that earns s
of 1 year, the certificate was worth $1,857.60.
What is the annual interest rate on this certificate of deposit
Answer:
3.2%
Step-by-step explanation:
The computation of the annual rate of interest is shown below:
As we know that
Simple interest = Principal × rate of interest × time period
($1,857.60 - $1,800) = $1,800 × rate of interest × 1
$57.60 = $1,800 × rate of interest × 1
So, the rate of interest is
= $57.60 ÷ $1,800 × 100
= 3.2%
Hence, the rate of interest on annual basis is 3.2%

Solve the inequality for x. –3x + 6 < 15 Question 1 options: x > –7 x < –7 x < –3 x > –3
Answer:
x < - 3
Step-by-step explanation:
Given the inequality :
-3x + 6 < 15
Collect like terms :
-3x < 15 - 6
-3x < 9
Divide both sides by - 3
-3x / 3 < 9/3
x < - 3 (sign changes as we have divides by a negative)

The solutions to the quadratic equation 5x² - 7x - 18 = 0 are [tex]\frac{7-\sqrt{ 409} }{10} \ and \ \frac{7+\sqrt{ 409} }{10}[/tex].
What are the solutions to the quadratic equation?Given the quadratic equation in the question:
5x² - 7x - 18 = 0
Compared to the standard form ax² + bx + c = 0:
a = 5, b = -7 and c = -18
To find the solutions to the quadratic equation, we use the quadratic formula:
[tex]x = \frac{-b\±\sqrt{b^2 - 4(ac)} }{2a}[/tex]
Plug in the values and simplify:
[tex]x = \frac{-(-7)\±\sqrt{(-7)^2 - 4(5*-18)} }{2*5} \\\\x = \frac{7\±\sqrt{( 49 +360)} }{10} \\\\x = \frac{7\±\sqrt{ 409} }{10} \\\\x = \frac{7-\sqrt{ 409} }{10}, \frac{7+\sqrt{ 409} }{10}[/tex]
Therefore, the values of x are [tex]\frac{7-\sqrt{ 409} }{10} \ and \ \frac{7+\sqrt{ 409} }{10}[/tex].

Answer:
The answer that is not true when x = -4 is B.
Step-by-step explanation:
Since x = -4, that means all we have to do to eliminate answers is plug -4 in place of x.
A is incorrect because 2 × -4 = -8, which means that answer IS true and we're looking for the one that isn't true.
Same with C, -4 + -4 + -4 added together gives you -12 = -12, therefore isn't the right choice.
Finally D. -4/4 divided equals -1, so that would make it -1 = -1.
B is the only one that doesn't make sense, therefore you have your answer.
