The solution to the questions are:
The width, labelled x in the figure is 87.5 metersThe length, labelled 350-2 x in the figure, is 175 metersThe largest area that can be enclosed is 15312.5 square metersHow to determine the width and the length of the rectangle?From the question, we have the following parameters that can be used in our computation:
Length = 350 - 2x
Width = x
The area of a rectangle is the product of its dimensions
So, we have
Area = Length x Width
Substitute the known values in the above equation, so, we have the following representation
A = (350 - 2x) * x
Evaluate
A = 350x - 2x²
Differentiate and set to 0
350 - 4x = 0
So, we have
4x = 350
Divide by 4
x = 87.5
Recall that
Length = 350 - 2x
So, we have
Length = 350 - 2 x 87.5
Evaluate
Length = 175
The area is then calculated as
Area = Length x Width
So, we have
Area = 175 x 87.5
Evaluate
Area = 15312.5 square meters
Hence, the area is 15312.5 square meters

What is an Arithmetic progression?Arithmetic Progression (AP) is a sequence of numbers in order, in which the difference between any two consecutive numbers is a constant value.
Arithmetic sequence is gotten by adding a known term by a constant value.
if [tex]a_{33}[/tex] = 66 and d = 2 and [tex]a_{n}[/tex] = [tex]a_{1}[/tex] + (n -1)d and n = 33
Then
[tex]a_{33}[/tex] = [tex]a_{1}[/tex] + 32d,
making [tex]a_{1}[/tex] subject of the equation we have
[tex]a_{1}[/tex] =66 - 32 x 2
[tex]a_{1}[/tex] = 66 - 64
[tex]a_{1}[/tex] = 2
if n = 30, [tex]a_{1}[/tex] =-2, d = 2

How to solve binomial probability distribution?The binomial probability is defined as the probability of exactly x successes on n repeated trials, with p probability. The general formula for binomial probability distribution is;
P(X = x) = ⁿCₓ * pˣ * (1 - p)^(n - x)
where;
P(X = x) is binomial probability
x is number of times for a specific outcome within n trials
ⁿCₓ is number of combinations
p is probability of success on a single trial
n is number of trials
Now, we are given that the probability of success for a particular region in Mexico being hit by hurricane is 0.07. Thus;

Martha had 12 2/3 yards of drapery material. She used 34 of it to make the drapes for her
family room. How much does she have left to make matching throw pillows?
The fraction that Martha has left to make matching throw pillows is 3 1/6 yards.
How to calculate the fraction?A fraction is simply a piece of a whole. The number is represented mathematically as a quotient where the numerator and denominator are split. In a simple fraction, the numerator as well as the denominator are both integers. On the other hand, a fraction appears in the numerator or the denominator of a complex fraction.
From the information given, Martha had 12 2/3 yards of drapery material. She used 3/4 of it to make the drapes for her family room.
Since 3/4 has been used, the fraction left will be gotten by subtracting the fraction that had already been used from the total fraction that she has. In this case, it should be noted that this will be illustrated as:
Total fraction that Martha has - The fraction that has been used
= 1 - 3/4
= 1/4
Therefore, the fraction will be the fraction that is left multiplied by the yards of drapery material that Martha had at the beginning. This will be:
= Fraction unused × Total yards of material
= 1/4 × 12 2/3
= 1/4 × 38/3
= 19/6
= 3 1/6
The fraction is 3 1/6 yards.

What is the gradient of the function?
A function's gradient is also known as its slope, and the slope (of a tangent) at a given point on a function is known as its derivative.
We have,
g(x) = ax³ + 3x² + bx + c
Take the derivative of the function with respect to x, then substitute the x-coordinate of the point of interest in for the x values in the derivative to find the gradient.
to know the gradient of the function ax³ + 3x² + bx + c at the point (-1, -7) we would do the following:
Take the derivative with respect to x:
g'(x) = 3ax² + 6x + b
Substitute the x-coordinate (x = -1)in for x:

Answer: (0,0),(−5,0),(2,0)
Answer: (0,0), (-5,0), (2,0)
Step-by-step explanation:
c(t)=4t⁴+12t³-40t²
1) t=0
c(t)= 4(0⁴)+12(0³)-40(0²)
c(t)=4(0)+12(0)-40(0²)
c(t)=0+0+0
c(t)=0

2) c(t)=0
4t⁴+12t³-40t²=0
Divide both parts of the equation by 4:
t⁴+3t³-10t²=0
t²(t²+3t-10)=0
t²=0
t=0

In a college, a full-time faculty member typically puts in 43 hours each week.
We have to find how many faculty members work more than 48.6 hours each week, assuming the standard deviation is 2.8 hours.
What is z-score?The Z-score determines the measure's standard deviations away from the mean. After calculating the Z-score, we look at the p-value associated with it in the z-score table. This p-value is the probability that the measure's value is smaller than X, or the percentile of X. By subtracting 1 from the p-value, one can determine the likelihood that the value of the measure is greater than X.
In a college, a full-time faculty member typically puts in 43 hours each week. 2.8 hour standard deviation.
This means μ=43 and σ=2.8
What proportion of academic staff employees put in more than 58.6 hours each week.
When X = 48.6, the proportion is calculated by deducting 1 from the p-value of Z.
So,
Z=X-μ/σ
Z=48.6-43/2.8
Z=5.6/2.8

What is median ?
The value of the middle observation found after the data are arranged in ascending order is referred to as the median of the data. In many cases, it is challenging to take all of the facts into account when representing something, and in these cases, median is helpful. The median is one of the simple to compute statistical summary metrics. The median is also known as the place average since it uses the data that is in the centre of a sequence to determine its value.
