Answers
This solution is as follows:
{[(20-32)/(-6)]^2-11}/(-7)
We can calculate the first bracket:
{[-12/(-6)]^2-11}/(-7)
We can then calculate -12/(-6)
(2^2-11)/(-7)
Then calculate 2^2
(4-11)/(-7)
Then calculate 4-11:

Find the equation of the line that passes through (-1,-3) and is perpendicular to 2 y = x − 3 . Leave your answer in the form y = m x + c
Answers
Answer:
Remember that the slope of perpendicular lines are negative reciprocals of each other.Step-by-step explanation:y = 1 - 2x the slope is -2 the value of the x term.So the slope of the new line using point (- 1, 2) is 1/2.Now use y = mx + b where y = -1, x = 2, and m = 1/2 .y = mx + b-1 = 1/2(2) + b solve for "b", the y-intersect-1 = 1 + b-2 = bThe line that is perpendicular to y = 1 - 2x is y = 1/2x - 2

11. you suspect a 6-sided die to be loaded and conduct a probability experiment by rolling the die 400 times. the outcome of the experiment is listed in the following table. do you think the die is loaded? why?
Answers
There is insufficient evidence to prove that the dice are loaded because every number on them has a probability of 1/6.
The likelihood of any number appearing on a six-sided die is 1/6.
It will not be 1/6 if it is loaded.
In order to determine whether the provided distribution complies with the idealized distribution of the dice throw, we do a chi-square test.
Step 1: Form the hypothesis.
H₀ = The likelihood of rolling any number on a six-sided die is one-sixth.
H₁ = The likelihood of getting any number on a six-sided die is not one in six.
Step 2: Indicate the degree of significance.
Alpha = 0.5
Step 3: computation of the chi-square test statistic (Image is attached for this step)
Step 4: Discover the important value.
Critical Value ⇒ 12.8325 =CHISQ.INV[1 - (0.05 / 2), 5]
Step 5: Determine the p-value.
p-value ⇒ 0.853 =1 - CHISQ.DIST(1.97,5,TRUE)
Step 6: Make a choice regarding whether or not to reject H₀
We are unable to reject the null hypothesis since the p-value is higher than 0.05.
As a result, we draw the conclusion that there is a 1/6 chance of getting any number on a six-sided die.
Note: Since the chi-square value is below the threshold, the null hypothesis cannot be rejected.
Because every number on the dice has a probability of 1/6, there is insufficient evidence to support the assertion that the dice are loaded.

Jada has a new puppy that weighs 9 pounds. the vet says that the puppy is now at about 20% of its adult weight. what will be the adult weight of the puppy?
Answers
The adult weight of the puppy calculated using percentage is 45 pounds .
In mathematics, a value or ratio that can be expressed as a simple fraction of 100 is known as a percentage.
When determining a percentage of a number, we should first divide it by 100 before multiplying the result by 100.
As a result, the proportion refers to a component per 100. The word percent denotes a percentage of 100.
It is represented by the symbol "%." Percentages can also be written as decimals or fractions, like in 0.6%, 0.25%, etc.
Academic grades are calculated using percentages for every subject. Ram, for example, received a 78% on his qualifying exam.
The weight of the puppy is 9 pounds.
This is 20% of the adult weight.
Let the adult weight be x.
therefore 20% of x = 9
Calculating we get x = 45 pounds
Hence the adult weight of the puppy is 45 pounds.

Answers:
15) x= −1 and y=2
16) x=2 and y= −1
Step-by-step explanation:
15) Solve the system by elimination:
Multiply the first equation by 2 and the second equation by 1.
2(8x−6y=−20)
1(−16x+7y=30)
They then become:
16x−12y=−40
−16x+7y=30
Add the two equations to eliminate x:
−5y=−10
Then solve for y by dividing both sides by -5:
−5y/−5 = −10/−5
The answer for y is y=2
Now Substitute 2 for y in the equation 8x−6y=−20:
8x−(6)(2)=−20
8x−12=−20
Add 12 to both sides:
8x−12+12=−20+12
8x=−8
Divide by 8:
8x/8 = −8/8
The answer for x is x=−1
16) Solve the system by elimination:
Multiply the second equation by 6 and merge the equations together.
(6x−12y=24)
6(−x−6y=4)
They then become:
6x−12y=24
−6x−36y=24
Add the two equations to eliminate x:
−48y=48
Then solve for y:
−48y=48
−48y/−48 = 48/−48
The answer for y is y= −1
Now substitute −1 for y in 6x−12y=24:
6x−(12)(−1)=24
6x+12=24
Add -12 to both sides:
6x+12+−12=24+−12
6x=12
6x/6 = 12/6
The answer for x is x=2

[tex]\qquad \sf \dashrightarrow \: 16x - 12y = - 40 \: \: \: \: \: \: - (3)[/tex]
Now, Add equation (3) and equation (2)
[tex]\qquad \sf \dashrightarrow \: 16x - 12y - 16x + 7y = - 40 + 30[/tex]
[tex]\qquad \sf \dashrightarrow \: - 5y = - 10[/tex]

Plug the value of y in equation (1) :
[tex]\qquad \sf \dashrightarrow \: 8x - 6y = - 20[/tex]
[tex]\qquad \sf \dashrightarrow \: 8x - 6(2) = - 20[/tex]
[tex]\qquad \sf \dashrightarrow \: 8x - 12 = - 20[/tex]
[tex]\qquad \sf \dashrightarrow \: 8x = - 20 + 12[/tex]
[tex]\qquad \sf \dashrightarrow \: x = - 8 \div 8[/tex]
[tex]\qquad \sf \dashrightarrow \: x = - 1[/tex]
So, the required values are : x = -1 and y = 2

[tex]\qquad \sf \dashrightarrow \: - 2x - 12y = 8 \: \: \: \: \: \: - (3)[/tex]
Now, subtract equation (3) from equation (1)
[tex]\qquad \sf \dashrightarrow \: 6x - 12y - ( - 2x - 12y) = 24 - 8[/tex]
[tex]\qquad \sf \dashrightarrow \: 6x - 12y + 2x + 12y= 16[/tex]
[tex]\qquad \sf \dashrightarrow \: 8x = 16[/tex]
[tex]\qquad \sf \dashrightarrow \: x = 16 \div 8[/tex]
[tex]\qquad \sf \dashrightarrow \: x = 2[/tex]
Now, plug x = 2, in equation (2) :
[tex]\qquad \sf \dashrightarrow \: - x - 6y = 4[/tex]
[tex]\qquad \sf \dashrightarrow \: - 2 - 6y = 4[/tex]
[tex]\qquad \sf \dashrightarrow \: - 6y = 4 + 2[/tex]
[tex]\qquad \sf \dashrightarrow \: - 6y = 6[/tex]

How to obtain the expected value of a discrete distribution?The expected value of a discrete distribution is obtained with the sum of each outcome multiplied by it's probabillity.
In this problem, the distribution for the prizes is given as follows:
P(X = 10,000,000) = 1/300,000,000.P(X = 350,000) = 1/150,000,000.P(X = 50,000) = 1/10,000,000.P(X = 20,000) = 1/1,000,000.P(X = 400) = 1/200,000.P(X = 75) = 1/6,000.Hence the expected value for the prizes is:
E(X) = 10,000,000 x 1/300,000,000 + 350,000 x 1/150,000,000 + 50,000 x 1/10,000,000 + 20,000 x 1/1,000,000 + 400 x 1/200,000 + 75 x 1/6,000 = $0.075.

The test is one of the form Hₐ < ; that means is a right tail test, and the value z(p) is bigger than our critical value (z(c) = 1.64) so we rejecte H₀
According to problem ststement : We need to solve an Hypotesis test proportion so:
H₀ P₀ = 0,4 and Hₐ < 0,4 ( Alternative hipotesis)
From a random sample of 700 employes 305 are determined to earn more than $ 50000
Proportion pₐ = 305/700 = 0,4357 pₐ = 0,4357
proportions are p = 0.4 and q = 0,6
We will asume a confidence level of 95 % hence α= 1-0,95 α = 0,05
so from z table we find z(c) = 1,64
Therefore we must calculate our z(p) = ( pₐ-p₀) ÷√(p*q)/n
Calculating z(p) = 0,0357 /0,01851 ⇒ z(p) 1.9286
Our test is one of the form Hₐ < ; that means is a right tail test, and the value z(p) is bigger than our critical value (z(c) = 1.64) so we rejecte H₀

(round to 2 decimal places)
Answers
There is a 0.0228 percent chance of getting a sample mean this big or bigger.
Given that the sample size is 64, the sample size is 3.2, and the standard deviation is 0.8.
The likelihood of a mean of 3.4 is determined as follows:
#First determine the z-value:
[tex]z=\frac{\bar{X}-\mu}{\sigma / \sqrt{n}}$$=\frac{3.4-3.2}{0.8 / \sqrt{64}}$$=2.000$[/tex]
#We then determine the corresponding probability on the z tables:
[tex]Z(X \geq 3.4)=1-P(X < 3.4)$$=1-0.97725$$=0.0228$[/tex]
Hence, the probability of obtaining a sample mean this large or larger is 0.0228.
The sample mean is regularly distributed for samples of any size derived from a population with a normal distribution, with mean X= and standard deviation X=/n, where n is the sample size.

20 ft/sec must she let out the string when the kite is 500 ft away from her.
What is rate?
A rate is a unique ratio where the two words are expressed in several units.
For instance, the price is 69 for 12 ounces if a 12-ounce can of maize costs 69. This is not a proportion of two comparable units, like shirts. Cents and ounces are the two dissimilar units in this ratio.
Let x = distance of girl from the point on the ground directly below the kite at time t
y = length of string at time t
At time t, we have a right triangle with horizontal leg of length x, vertical leg of length 300, and hypotenuse of length y.
Given: dx/dt = 25
Find: dy/dt when y = 500
By the Pythagorean Theorem, [tex]x^2 +300^2 = y^2[/tex]
Differentiating both sides, with respect to t,
[tex](2x)\frac{dx}{dt} = 2y\frac{dy}{dt}[/tex] ...(1)
Since, [tex]x^2 +300^2 = y^2[/tex], y = 500,
So, x = 400
Plug these values in equation (1).
[tex]2(400)(25) = 2(500)\frac{dy}{dt}[/tex]
After solving,
[tex]\frac{dy}{dt} = 20 ft/sec[/tex]

Answers
The expressions that represent the volume of metal needed , to make the pipe are (a)21*π*(10)² - 21*π*(6)² and (c)2100π - 756π .
In the question ,
it is given that
the diameter of the cylindrical metal pipe = 20mm
so the radius of the cylindrical pipe = 10 mm
height of the cylindrical metal pipe = 21mm
Using the formula of Volume of Cylinder = π*r²*h
the volume of cylindrical metal pipe = π*(10)²*21 .....(i)
the height of smaller cylinder = 21mm
radius of the smaller cylinder = 6mm
So, Volume of the smaller cylinder = π*(6)²*21 .....(ii)
the volume of metal needed to make the pipe = Volume of cylindrical metal pipe - Volume of the smaller cylinder .
Substituting the values from (i) and (ii) , we get
volume of metal needed = π*(10)²*21 - π*(6)²*21
= 21*π*(10)² - 21*π*(6)²
hence , option(a) is correct .
Further Simplifying , we get
= 21*100*π - 21*36*π
= 2100π - 756π

What does "fraction" mean?An element of a whole is a fraction. The number is represented mathematically as a quotient, where the numerator and denominator are split. Both are integers in a simple fraction. A fraction appears in the numerator or denominator of a complex fraction. The numerator of a proper fraction is less than the denominator.
A fraction is referred to as the portion of a whole in mathematics. For instance, if a pizza is cut into four equal pieces, each one is represented by a quarter. Fractions make calculations quicker and easier by making it easier to distribute and judge numbers.
Reduce the fractions if they aren't already in the lowest terms. Then, all that is required is to multiply the denominator by the denominator and the numerator by the numerator. For instance, multiplying 2 by 7 yields the new numerator, which is 14, when multiplying 2/3 and 7/8. The result of multiplying 3 by 8 is 24.
