Answer:
A) minimum of -2Answer:
A. minimum at x = -2.
Step-by-step explanation:
Finding the derivative:
f'(x) = 12x.
12x = 0 for a maxim/ minimum.
x = 0.
As the second derivative (12) is positive, we have a minimum value when x = 0.
So the function has a minimum value where f(x) = 6(0)^2 -2 = -2.

And orange falls of a display at a store and rolls 5 meters in 2.5 seconds.What is the average speed of the orange
Answer:
The orange moves at 2M/s
5/2.5=2
2meters/secon
The average speed of the orange is 2 m/sec.
Given that, orange falls off a display at a store and rolls 5 meters in 2.5 seconds.
We need to find the average speed of the orange.
What is the average speed formula?Average speed is the mean value of the speed of a body over a period of time. The formula for average speed is needed since the speed of a moving body is not constant and varies across a period of time. Even with varying speeds, the values of total time and the total distance covered can be used, and with the help of the formula for average speed, we can find a single value to represent the entire motion.
The formula for average speed is given as:
Average Speed = Total distance covered ÷ Total time taken
Now, average speed=5/2.5=2 m/sec.
Therefore, the average speed of the orange is 2 m/sec.

A shopper in a grocery store purchases 22 items on average. A store manager believes that the mean is greater than 22. She surveyed a randomly selected group of 36 customers and found that the mean of the number of items purchased was 23.2. The population standard deviation is 3.7 items. At α = 0.05, can it be concluded that the mean is greater than 22 items?
Answer:
The is no significant evidence to conclude that mean is greater than 22
Step-by-step explanation:
H0 : μ = 22
H0 : μ > 22
The test statistic :
(xbar - μ) ÷ (σ/sqrt(n))
xbar = 22.3 ; n = 36 ; μ = 22 ; σ = 3.7
(22.3 - 22) ÷ (3.7/√36)
0.3 ÷ 0.6166666
Test statistic = 0.486
The Pvalue using a Pvalue calculator from Zscore is :
Pvalue = 0.313
α = 0.05
Pvalue > α ; We fail to reject the Null ; The is no significant evidence to conclude that mean is greater than 22

Mekala has an MP3 player called the Jumble. The Jumble randomly selects a song for the user to listen to. Mekala's Jumble has 4 techno songs, 2 country songs, and 3 jazz songs on it. Mekala plans to listen to 270 songs.
Answer:
Mekala Jumble has 4 techno songs, 2 country songs, and3 jazz songs on it.
Ratio of techno songs,to country songs,to jazz songs= 4: 2 : 3
Whatever be total number of songs, let the number of techno songs, country songs,and jazz songs be 4 x, 2 x, and 3 x.
Total number of songs that Mekala plans to Listen = 2 70
Then , 4 x + 2 x + 3 x= 270
9 x = 270
Dividing both sides by 9, we get
x = 30
So, Number of techno songs = 4 × 30= 120
Number of techno songs = 2 × 30= 60
Number of jazz songs = 3 × 30= 90
Option (b) b) Close to 60 country songs but probably not exactly 60 country songs ,is true option regarding number of songs listen by Mekala.

Answer:

Q3 #1: 19
IQR #1: 13.5
Median #2: 14
Q1 #2: 3
Q3 #2: 45
IQR #2: 42
Step-by-step explanation:
Question 1:
First order the data so that they are in order from least to greatest:
2, 5, 6, 8, 13, 16, 22, 24
Now, find the median by crossing out one value on the left and one value on the right until you get to the center value.
2, 5, 6, 8, 13, 16, 22, 24
/2/, /5/, /6/, /8/, /13/, /16/, /22/, /24/
In this case, there were four values crossed off of each side, so you'll need to find the average of the final two crossed out values: 8 and 13.
(8+13)/2 = 10.5
To find the first quartile, find the median of all values below the median.
2, 5, 6, 8
/2/, /5/, /6/, /8/
The median of these values is the average of the center two, so
(5+6)/2 = 5.5
The third quartile is the median of all values above the median.
13, 16, 22, 24
/13/, /16/, /22/, /24/
The median of those values is the average of the center two as well, so
(16 + 22)/2 = 19
The IQR can be found by subtracting Q1 from Q3. (IQR = Q3 - Q1)
Q3 - Q1
19 - 5.5
IQR = 13.5
Question 2:
Arrange the values from least to greatest and cross them out until you find the middle falue, like in problem one.
1, 3, 7, 14, 21, 45, 63
/1/, /3/, /7/, 14, /21/, /45/, /63/
The center value is 14, so the median is 14.
The first quartile can be found by finding the median of all values below the median.
1, 3, 7
/1/, 3, /7/
The first quartile is 3.
The third quartile can be found by finding the median of all values above the median.
21, 45, 63
/21/, 45, /63/
The third quartile is 45.
The interquartile range can be found using the equation from above.
Q3 - Q1
45 - 3
The interquartile range is 42.

[tex]\huge{ \mathfrak{ \underline{ Answer} \: \: ✓ }}[/tex]
let the number of
adults be x children be yTotal number of people : adults + children
x + y = 240x = 240 - y - [1]Total money earned from adults :
6 × x = 6xTotal money earned from children :
2 × y = 2yTherefore, total money = money earned from each Adult and children.
6x + 2y = 1200 -[2]Now, let's plug the value of x from equation [1] into equation [2]
6 (240 - y) + 2y = 12001440 - 6y + 2y = 1200-4y = 1200 - 1440-4y = - 240y = 60let's plug the value of y in equation [1]
x = 240 - yx = 240 - 60x = 180Hence, we get :
total adults = x = 180total children = y = 60Correct option is C

Alice has 4 red, 2 pink, 1 white, and 5 blue shirts in a drawer. Without looking, Alice pulled out a red shirt and put it on her bed. What is the probability Alice will pull out a blue shirt after she pulled out the red one?
The probability is 5/11 as a fraction, about 45%, and/or 0.45 as a decimal.
Probability formula: Possible values/ Favorable values
Step 1: add the possible values: 4 + 2 + 1 + 5. This is equal to 12 possible options.
Step 2: Since Alica pulled out a red shirt, there will be 11 possible options (12-1 shirt = 11 possible options)
Step 3: Since we are expecting a blue shirt and there are 5 blue shirts, there is a 5/11 chance. Hope this helps!

The measures of the angles of a triangle are in the extended ratio 3:3:10 what is the mesasure of the smallest angle?
Answer:
33.75°
Step-by-step explanation:
Given data
Ratio= 3:3:10
combined ratio= 3+3+10= 16
The sum of angles in a triangle is 180°
Hence the smallest angle is represented by the ratio 3
therefore let the angle be x
Applying the part to all method
3/16= x/180
16x= 180*3
16x=540
x= 540/16
x= 33.75°
Hence the smallest angle is 33.75°
If cos() = − 2 3 and is in Quadrant III, find tan() cot() + csc(). Incorrect: Your answer is incorrect.
Answer:
[tex]\tan(\theta) \cdot \cot(\theta) + \csc(\theta) = \frac{5 - 3\sqrt 5}{5}[/tex]
Step-by-step explanation:
Given
[tex]\cos(\theta) = -\frac{2}{3}[/tex]
[tex]\theta \to[/tex] Quadrant III
Required
Determine [tex]\tan(\theta) \cdot \cot(\theta) + \csc(\theta)[/tex]
We have:
[tex]\cos(\theta) = -\frac{2}{3}[/tex]
We know that:
[tex]\sin^2(\theta) + \cos^2(\theta) = 1[/tex]
This gives:
[tex]\sin^2(\theta) + (-\frac{2}{3})^2 = 1[/tex]
[tex]\sin^2(\theta) + (\frac{4}{9}) = 1[/tex]
Collect like terms
[tex]\sin^2(\theta) = 1 - \frac{4}{9}[/tex]
Take LCM and solve
[tex]\sin^2(\theta) = \frac{9 -4}{9}[/tex]
[tex]\sin^2(\theta) = \frac{5}{9}[/tex]
Take the square roots of both sides
[tex]\sin(\theta) = \±\frac{\sqrt 5}{3}[/tex]
Sin is negative in quadrant III. So:
[tex]\sin(\theta) = -\frac{\sqrt 5}{3}[/tex]
Calculate [tex]\csc(\theta)[/tex]
[tex]\csc(\theta) = \frac{1}{\sin(\theta)}[/tex]
We have: [tex]\sin(\theta) = -\frac{\sqrt 5}{3}[/tex]
So:
[tex]\csc(\theta) = \frac{1}{-\frac{\sqrt 5}{3}}[/tex]
[tex]\csc(\theta) = \frac{-3}{\sqrt 5}[/tex]
Rationalize
[tex]\csc(\theta) = \frac{-3}{\sqrt 5}*\frac{\sqrt 5}{\sqrt 5}[/tex]
[tex]\csc(\theta) = \frac{-3\sqrt 5}{5}[/tex]
So, we have:
[tex]\tan(\theta) \cdot \cot(\theta) + \csc(\theta)[/tex]
[tex]\tan(\theta) \cdot \cot(\theta) + \csc(\theta) = \tan(\theta) \cdot \frac{1}{\tan(\theta)} + \csc(\theta)[/tex]
[tex]\tan(\theta) \cdot \cot(\theta) + \csc(\theta) = 1 + \csc(\theta)[/tex]
Substitute: [tex]\csc(\theta) = \frac{-3\sqrt 5}{5}[/tex]
[tex]\tan(\theta) \cdot \cot(\theta) + \csc(\theta) = 1 -\frac{3\sqrt 5}{5}[/tex]
Take LCM
[tex]\tan(\theta) \cdot \cot(\theta) + \csc(\theta) = \frac{5 - 3\sqrt 5}{5}[/tex]
