HELPPPP PLZZZ ASAPPP!!!Look at the illustration of four letters from the American Manual Alphabet. Decide whether the description of the letter is a good definition. If not,
choose a counterexample.
The letter I is formed by sticking up the smallest finger and folding all the other fingers into the palm of your hand with the thumb folded over them.
The letter J is a counterexample
The letter y is a counterexample
The letter A is a counterexample
This is a good definition
while keeping your hand still
Answer: I think it’s J, because the picture is also holding the smallest finger up (the pinky) and the rest of the fingers are folded inside the palm of the hand and the thumb is folded over them, I hope this helps!!
Step-by-step explanation:
The letter J is a counter example. Option a is correct.
Letters of alphabet to be determine.
Alphabets are the sets of letters from A to Z.
Here, the little finger is up and all the finger is folded and the thumb folded over the three finger implies its 'J'.
Thus, the letter J is a counter example.

How many solution does 8(3x-6=6(x+8) have
Answer:
Step-by-step explanation:
at most 1.
8(3x - 6) = 6(x + 8)
24x - 48 = 4x + 48 Subtract 4x
24x - 4x - 48 = 4x -4x + 48 Combine
20x - 48 = 48 Add 48 to both sides.
20x = 96 divide by 20
x = 96/20
x = 4.8

The critical path for a project was found to be 37 days. The variances total 27. What is probability of completing in 43 days? Below is information that might be useful to answer the question. Answer to 2 decimal points
Answer:
0.1241.
Step-by-step explanation:
So, from the question we are given the following parameters or information or data which are going to help us in solving this particular question/problem. They are; [1]. The critical path for a project = 37 days, the variances total or variance of critical path or sum of variance on critical path]². = 27, the desired completion time/day = 43 days.
So, we will be making use of the formula given below;
The number of standard deviation = desired completion time/day - critical time or sum of critical path times ÷√[variance of critical path or sum of variance on critical path]².
The number of standard deviation = 43 - 37 ÷ √27 = 1.1547.
Thus, the probability of completing in 43 days = P(Z > 1.1547) = 0.1241.

Consider the following probability distribution function of the random variable X which represents the number of people in a group (party) at a restaurant: X P(X) 1 0.10 2 0.25 3 0.20 4 0.20 5 0.10 6 7 0.05 8 0.05 a. Find the population mean of X. b. Find the population variance and standard deviation of X. c. Find the probability that the next party will be over 4 people. d. Find the probability that the next three parties (assuming independence) will each be over 4 people.
Answer:
(a) 3.55
(b) 3.45 and 1.86
(c) 0.25
(d) 0.016
Step-by-step explanation:
The random variable X denotes the number of people in a group (party) at a restaurant.
(a)
The formula to compute the mean is:
[tex]\mu=\sum {x\cdot P(X=x)}[/tex]
Consider the Excel sheet attached.
The mean is, 3.55.
(b)
The formula to compute the variance is:
[tex]\sigma^{2}=[\sum {x^{2}\cdot P(X=x)}]-(\mu)^{2}[/tex]
Consider the Excel sheet attached.
Compute the variance as follows:
[tex]\sigma^{2}=[\sum {x^{2}\cdot P(X=x)}]-(\mu)^{2}\\\\=16.05-(3.55)^{2}\\\\=3.4475\\\\\approx 3.45[/tex]
The variance is, 3.45.
Compute the standard deviation as follows:
[tex]\sigma=\sqrt{\sigma^{2}}\\\\=\sqrt{3.45}\\\\=1.85742\\\\\approx 1.86[/tex]
The standard deviation is, 1.86.
(c)
Compute the probability that the next party will be over 4 people as follows:
[tex]P(X>4)=P(X=5)+P(X=6)+P(X=7)+P(X=8)\\\\=0.10+0.05+0.05+0.05\\\\=0.25[/tex]
Thus, the probability that the next party will be over 4 people is 0.25.
(d)
Compute the probability that the next three parties will each be over 4 people as follows:
It is provided that the three parties are independent.
P (Next 3 parties will be each over 4) = [P (X > 4)]³
[tex]=(0.25)^{3}\\=0.015625\\\approx 0.016[/tex]
Thus, the probability that the next three parties will each be over 4 people is 0.016.
A pair of jeans was 30% off the original price. The sale resulted in $24 discount.
Answer:
$80 is the 100% original price
The sale price is $56 with 30% off and $24 in savings.
Step-by-step explanation:
We can write a proportion. We know that $24 is a 30% off discount of an unknown original price. Let's call it x. We write equal ratios of comparing percent and comparing the 24 to the original price. We then set them equal.
We then cross multiply across the equal sign from numerator to the opposite numerator.
30(x)=24(100)
30x=2400
We divide to find x.
x=80.
Since we saved $24 as a discount, the sale price would be 80-24=56.

Lamark goes to a bowling alley to test his belief that rolling a bowling ball slowly will result in knocking down more pins. He gently rolls his bowling ball towards the bowling pins lined up at the end of the lane. The bowling ball stops in the middle of the lane without striking the pins. Which statement below best explains what happened?
Answer: Ball's kinetic energy became potential energy
Step-by-step explanation:
There are no options attached but this should be along the lines of what happened.
Kinetic energy refers to energy that an object has as a result of it moving whilst potential energy is the opposite and is energy that an object stores within itself due to several factors whilst it is not in motion.
The ball was initially in motion which means that it had kinetic energy but as the ball was slowing down, this energy was gradually converted to potential energy until the balls came to a standstill.
Which equation represents the line that passes through the
points (2,7) and (1, 4)?
Answer:
y=3x+1
Step-by-step explanation:
Use the slope formula and slope-intercept form y = m x + b to find the equation.
Answer:
(-4,3),(2,-12)
slope = (-12 - 3) / (2 - (-4) = -15/6
Step-by-step explanation:
y = mx + b
slope(m) = -15/6
use either of ur points...(-4,3)...x = -4 and y = 3
now we sub into the formula and find b, the y int
3 = -15/6(-4) + b
3 = 10 + b
3 - 10 = b
-7 = b
so ur equation is : y = -15/6x - 7....but we need it in standard form
y = -15/6x - 7...add 15/6 to both sides
15/6x + y = -7...multiply both sides by 6
15x + 6y = -42....which reduces to 5x + 2y = - 14 <===

The volume of a cone is 84pi cubic inches. If the radius of the cone is 6 inches determine its height
Answer:
7 inches
Step-by-step explanation:
Given
Shape: Cone
[tex]Volume = 84\pi in^3[/tex]
[tex]Radius = 6in[/tex]
Required
Determine the height
Volume of a cone is:
[tex]V = \frac{1}{3}\pi r^2h[/tex]
Substitute values for volume and radius
[tex]84\pi = \frac{1}{3}\pi * 6^2 * h[/tex]
[tex]84\pi = \frac{1}{3}\pi * 36 * h[/tex]
[tex]84\pi = \frac{36}{3}\pi* h[/tex]
[tex]84\pi = 12\pi* h[/tex]
Solve for h
[tex]h = \frac{84\pi}{12\pi}[/tex]
[tex]h = 7[/tex]

The height is 7 inches
Find the measure of the missing angle
Answer:
M1=108° M2=72°
Step-by-step explanation:
M1 and the original 108° angle are equal, and to calculate M2, which is on the same straight line as the original 108°, we must remember that all angles on a straight line add up to 180°. So, 180-108=72, making M2 72°
divide and answer in simplest form: 1/3 divided by 5
Answer:
1/15
Step-by-step explanation:
1. You can divide 1/3 by 5 by changing the division symbol to its reciprocal, multiplication, and also divide by the reciprocal of the number after the symbol, 5. The reciprocal of 5 is 1/5.
2. Now you can do 1/3 multiplied by 1/5. Multiply the numerators by the denominators. The numerators are 1 and 1, so you multiply 1 by 1 which equals 1. Now you multiply the denominators, 3 and 5, which is equal to 15. If the numerator is now 1, and the denominator is 15, the new fraction is 1/15, getting you to your answer

Looking around in your own country, discuss two practical applications in which “piecewise functions” are used either explicitly or implicitly
Answer:
Piecewise functions are functions that behave differently in different regions of the domain.
One example that you may see in your city is the case of the street illumination, such that can be modeled as:
x = time
Suppose that the lights are turned on at a given hour x0 and then turn off at the hour x1, we can define:
f(x) = 0 if x1 < x < x0
f(x) = 1 if x0 ≤ x ≤ x1
Where f(x) represents the intensity of the light at the time x.
Between x1 and x0, the lights are not working, so the illumination that they provide is zero.
Between x0 and x1 the lights are turned on, so the illumination is 1.
Another example can be the accurate description of the velocity of a car as a function of time.
For some pieces, the car will be stopped (maybe in a red light)
For some pieces, the car will be moving slow (maybe there is a lot of traffic)
For some pieces, the car will be moving fast or accelerating (in an empty street).
So we can define this motion as a piecewise function that obviously will depend on how the car moves.

Answer:
The amount of money invested at 15% = 30,000
The amount of money invested at 5% = 30,000
Step-by-step explanation:
Calculation for How much money should be invested
Let x dollars = 15%,
Let y dollars= 5%,
x + y = 60,000
0.15x + 0.05y = 6,000
Multiply the 1st Equation by -0.15:
-0.15x - 0.15y = -9,000
0.15x + 0.05y = 6,000
Add the 2 Equations :
-0.1y = -3,000
y=3,000/0.1
y = 30,000
Substitute 30,000 for y in the 1st Equation
x + 30,000 = 60,000
x = 60,000 - 30,000
x= 30,000
PROOF:
.15*30,000+.05*30,000=6,000
4,500+1,500=6,000
6,000=6,000
Hence,
The amount of money invested at 15% = 30,000
The amount of money invested at 5% = 30,000
