A department store is hiring for the positions of manager, associate manager, and assistant manager. If 15 people have applied for all the positions and are equally qualified for each position, in how many ways can the positions be filled?
Answer:
The positions can be filled in 2730 ways
Step-by-step explanation:
The number of all posible ways is equal to the number of possibilities of who can become the manager, times the number of possibilities of who can become the associate manager, times the number of possibilities of who can become the assistant manager.
Now...
The number of possibilities of who can become the associate manager = 15
The number of possibilities of who can become the associate manager = 14
(it decrease by one because one person already got the position of manager)
The number of possibilities of who can become the assistant manager = 13
(based on the same logic as for the number of who can become the associate manager)
So now we know the number of ways equals...
15 x 14 x 13 = 2730
Pythagorean theorem level 2 delta math
The third side is [tex]\sqrt{42}[/tex]
So Pythagorean's theorem is the following
[tex]Short^2 + Long^2 = Hypotenuse^2[/tex]
From here we can input the following information that we know
[tex]Short^2 + 4\sqrt{3}^2 = 8^2\\Short^2 + 12 = 64\\Short^2 = 64 - 12\\Short^2 = 42\\Short = \sqrt{42}\\[/tex]

Use the line to split the shape. For P add all the numbers and add a 4 and a 1 too. For the area, you have to multiply 2 by 2 because of the cube, then mulitply 4 by 1 because 2+2=4 and the other number is one. REMEMBER TO SHOW YOUR WORK AND DOUBLE-CHECK!
Factor the expression to find the zeros
Answer:
k = (1 , 4)
Step-by-step explanation:
here's your solution
==> k^2 - 5k + 4. [ is expression ]
==> by using middle term split
==> k^2 - 4k - k + 4
==> taking common from each
==> k(k - 4) - 1 (k - 4)
==> (k - 1) , (k - 4).
==> k - 1 = 0
==> k = 1
==> k - 4 = 0
==> k = 4
hence , k = (1 , 4)

Answer:
Step-by-step explanation:
Use SOH CAH TOA to recall how the trig functions fit on a triangle
SOH: Sin(Ф)= Opp / Hyp
CAH: Cos(Ф)= Adj / Hyp
TOA: Tan(Ф) = Opp / Adj
well you know it's a 90° so do you know what Sin(90) is? you should :D
I think this is kinda a trick question too b/c Opp here is also Hyp
so it would like like sin(90) = Opp / Hyp but that's 427/427 for this question. seems kinda confusing why ask it that way.. huh :/
sin(90) = 1

Suppose a sample of 256 was taken from a population with a standard deviation of 64 centimeters. What is the margin of error for a 68% confidence interval?
A. 6
B. 8
C. 10
D. 4
The correct margin of error for a 68% confidence interval is option D 4 centimeters.
Let's calculate the margin of error correctly for a 68% confidence interval.
To calculate the margin of error, we need to determine the critical value associated with a 68% confidence interval. For a normal distribution, the critical value is approximately ±1 standard deviation.
Given that the standard deviation is 64 centimeters, the margin of error can be calculated as:
Margin of Error = 1 * (Standard Deviation / √Sample Size)
= 1 * (64 / √256)
= 1 * (64 / 16)
= 1 * 4
= 4
Therefore, the correct margin of error for a 68% confidence interval, based on the given information, is 4 centimeters. The correct answer is option D.

Two decimals numbers, to the thousandths, that have a sum of about 5 and a difference of about 3. Then do the math to prove it works.
Answer:
The numbers are approximately: 4.000 and 1.000
Step-by-step explanation:
The given parameters can be expressed as:
[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]
[tex]\frac{x}{1000} - \frac{y}{1000} \approx 3[/tex]
Required
Determine the numbers
In each of the equations, multiply by 1000
[tex]1000 * [\frac{x}{1000} + \frac{y}{1000} \approx 5][/tex]
[tex]x + y \approx 5000[/tex]
[tex]1000 * [\frac{x}{1000} - \frac{y}{1000} \approx 3][/tex]
[tex]x-y \approx 3000[/tex]
So, we have:
[tex]x + y \approx 5000[/tex]
[tex]x-y \approx 3000[/tex]
Add the two equations
[tex]x + x + y - y \approx 5000 + 3000[/tex]
[tex]2x \approx 8000[/tex]
Solve for x
[tex]x \approx 8000/2[/tex]
[tex]x \approx 4000[/tex]
Substitute [tex]x \approx 4000[/tex] in [tex]x + y \approx 5000[/tex]
[tex]4000 + y \approx 5000[/tex]
[tex]y \approx 5000 - 4000[/tex]
[tex]y \approx 1000[/tex]
Using:
[tex]\frac{x}{1000} + \frac{y}{1000} \approx 5[/tex]
We have:
[tex]\frac{4000}{1000} + \frac{1000}{1000} \approx 5[/tex]
[tex]4.000 + 1.000 \approx5[/tex]
This implies that, the numbers approximates to 4.000 and 1.000, respectively.
Question
An ant weighs 8.8x10 pound and can
carry objects up to 5,000 times greater than
its own body weight.
What is the greatest weight, in pounds, the
ant can carry?
Express your answer in standard form.
Answer: 880000
Step-by-step explanation: 8.8 x 10^ 5 = 880000
An ant can carry 0.044 pound of weight.
Important information:
Weight of an ant is 8.8x10⁻⁶ poundThey can carry objects up to 5,000 times greater than their own body weight.Standard form:Weight of an ant in standard form is:
[tex]8.8x10^{-6}=8.8\times \dfrac{1}{1000000}[/tex] pound
[tex]8.8x10^{-6}=0.0000088[/tex] pound
They can carry objects up to 5,000 times greater than their own body weight. So, the possible weight they can carry is:
[tex]0.0000088\times 5000=0.044[/tex]
Therefore, an ant can carry 0.044 pound of weight.
