Cecil weighs the same as the combined weight of Bruce and Alan. Use the expressions you found in parts A and B to write an expression
for Cecil's weight in terms of Dylan's weight.
Answers
Answer: Cecil’s weight is the sum of Alan's weight and Bruce's weight.
Alan’s weight in terms of Dylan's weight is 2d + 3.
Bruce’s weight in terms of Dylan's weight in 3d − 12.
So, the expression for Cecil’s weight in terms of Dylan’s weight is (2d + 3) + (3d − 12).

Step-by-step explanation:
You can simplify the equation by distributing the 9 in:
y = 18x ⇒ And this equation is indeed linear
So, that means that y = 9(2x) is linear
Hope this helps! :)
y = 9(2x) is a linear function as the function given exactly one output for one input.
Given that,
To determine whether the given expression is a linear function or nonlinear function,
Functions are the relationship between sets of values. e g y=f(x), for every value of x there is its exists in a set of y. x is the independent variable while Y is the dependent variable.
Here,
The given function y = 9(2x)

What is the total amount accrued in the given period of time?Annuity is simply a mechanism to create substantial amount in future by making relatively very small periodic payments up until maturity.
It is expressed mathematically as;
F = P × (( (1+r)^(nt) - 1 )/r)
Given the data in the question;
Annual deposit amount P = $2,500Annual interest rate r = 8% = 8/100 = 0.08Compounded annually = Ones in a year = 1Time t = 30 yearsFuture value = ?Plug the given values into the equation above and solve for A.
F = P × (( (1+r)^(nt) - 1 )/r )
F = 2500 × ( ((1 + 0.08 )^(1×30) - 1 ) / 0.08 )
F = 2500 × (( (1.08 )³⁰ - 1 ) / 0.08 )
F = 2500 × ( 10.06265688 - 1)/0.08 )

At a particular factory, every product is inspected by two men. The first inspector catches 80% of the defectives and sends them back for repairs. All the remaining items are sent to a second inspector, who misses about 40% of the defectives that get past the first inspector.
Given that a product was found to be defective, what is the probability that it was found by the first inspector?
Answers
The probability that a defective product was found by the first inspector is 80% since the first inspector catches 80% of the defectives.
What is probability?Probability is a linear scale measurement of the likelihood of an outcome occurring out of many possible outcomes.
Probability refers to the chance that something or an event happens when other events could have occurred.
Probability is measured in percentages, fractions, or decimals. The probability of an outcome does not exceed one. When it is one, it shows that the event is certainly going to happen.
Data and Calculations:Percentage of defectives found by the first inspector = 80%
Percentage of defectives not found by the first inspector = 20% (1 - 80%)
Percentage of defectives not found by the second inspector = 40%
Percentage of defectives found by the second inspector = 60% (1 - 40%)
Thus, the probability that a defective product was found by the first inspector is 80% since the first inspector catches 80% of the defectives.

Explanation:
Rule: We cannot divide by zero.
Because of that rule, we'll set the denominator equal to zero and solve for x. This way we can determine the x value(s) that are to be excluded from the domain.
6 - |x-1| = 0
|x-1| = 6
x-1 = 6 or x-1 = -6
x = 6+1 or x = -6+1
x = 7 or x = -5
Those x values are to be excluded from the domain, since they make the denominator zero.
Imagine a number line in which we poked open holes at -5 and 7
The portion to the left of -5 is x < -5The portion between -5 and 7 is -5 < x < 7The portion to the right of 7 is x > 7Combining everything gets us x < -5; -5 < x < 7; x > 7

You measure 47 backpacks' weights, and find they have a mean weight of 79 ounces. Assume the population standard deviation is 13.1 ounces. Based on this, what is the maximal margin of error associated with a 90% confidence interval for the true population mean backpack weight.
Give your answer as a decimal, to two places
Answers
Answer:
3.14
Step-by-step explanation:
Given that:
Mean weight (m) = 79 ounces
Population standard deviation (s) = 13.1
Sample size = 47
Maximal margin of error associated with 90% confidence interval.
The margin of error is given by:
Zcritical * (standard deviation / sqrt(sample size)
Z critical at 90% confidence interval = 1.645
Hence,
Zcritical * (standard deviation / sqrt(sample size)
1.645 * 13.1 / sqrt(47)
1.645 * (13.1 / 6.8556546)
1.645 * 1.9108313
Hence, the margin of error is :

The value of cotθ where θ is in fourth quadrant is [tex]-\frac{5}{\sqrt{171} }[/tex] which is option (A).
Trigonometric ratios are defined as the values of all trigonometric functions based on the aspect ratio values of a right triangle. The ratio of the sides of a right triangle to one of its acute angles is known as the trigonometric ratio of that particular angle. The three sides of a right triangle are: hypotenuse (longest side) , vertical (opposite of angle) , Base (side adjacent to corner) According to the Pythagorean theorem, in a right triangle (90 degrees), the square of the hypotenuse equals the sum of the squares of the other two sides.
It is given that cosθ = 5 /14 . ....(1)
As we know that cosθ = Base / Hypotenuse ...(2)
On comparing equation (1) and (2) , we get
Base = 5 and Hypotenuse = 14
Using Pythagorean theorem , we get
Hypotenuse² = Perpendicular² + Base²
14² = P² + 5²
196 = P² +25
171 = P²
± [tex]\sqrt{171}[/tex] = P
Then , cotθ = Base / Perpendicular
= ±[tex]\frac{5}{\sqrt{171} }[/tex]
As in fourth quadrant cotθ is negative so cotθ will be negative.
So , we will consider the negative value .
Cotθ = - [tex]\frac{5}{\sqrt{171} }[/tex]

THE DIFFERENCE OF
TWO NUMBERS IS 10,WHILE THEIR PRODUCT IS 39.FIND THESE NUMBERS
Answers
The numbers are 13 and 3.
Let the numbers be x and y. Equation representing difference of these numbers-
x - y = 10 : equation 1
Equation representing product of these numbers- x × y = 39 : equation 2
Rewriting the equation 2 in terms of y
y = 39/x : equation 3
Keeping the value of y from equation 3 in equation 1
x - 39/x = 10
Multiplying the equation by x
x² - 39 = 10x
Rearranging the equation
x² - 10x - 39 = 0
Factorising the equation
x² - 13x + 3x - 39 = 0
x(x - 13) +3 (x - 13) = 0
(x + 3) (x - 13) = 0
Value of x = 13 and -3
Taking positive value of x
Keeping value of x in equation 3
x = 13
y = 39/13
