By using Pythagoras' theorem the required length of the cable  is 85 feets.

The square of the hypotenuse side in a right-angled triangle is equal to the sum of the squares of the other two sides, according to Pythagoras' theorem. Perpendicular, Base, and Hypotenuse are the names given to the triangle's sides. The hypotenuse is the longest side in this case because it is opposite the angle of 90°.

The Pythagorean theorem states that the square of the length of the hypotenuse is equal to the sum of the squares of the lengths of the other two sides of a right-angled triangle. Alternatively, the sum of the squares of a right triangle's two legs equals the square of its hypotenuse.

Given:

Height of the tower = 68 feet = perpendicular

distance of box form tower = 51 feet = base

Let's assume lenght of the cable = L = hypotenous

Acoording to the question by using Pythagoras' theorem,

[tex]hyp^{2}= perpendicular^{2} +base^{2} \\(L)^2 = (68)^2 + (51)^2\\L^2 = 4624 + 2601\\L^2 = 7225\\L =\sqrt{7225}\\L = 85 feet[/tex]

Hence by using Pythagoras' theorem the required length of the cable  is 85 feets.

Because it permits one to assume that the sampling distribution of the mean would typically be normally distributed, the central limit theorem is helpful when examining big data sets. This makes statistical analysis and inference simpler.

Hypothesis :

In statistics, hypothesis testing is used to identify the variance in the group of data that results from genuine variation. Based on the presumptions, the sample data are taken from the population parameter. The hypothesis can be divided into many categories. A hypothesis is described in statistics as a formal statement that explains the relationship between two or more variables belonging to the specified population.

The best prediction of the population in the year 2015 will be 4150

rate of decrease involves The rate of reduction expressing a decrease as a percentage of the initial value.To compute a percentage drop, first determine the difference (decrease) between the two values being compared. Then, divide the reduction by the original number and multiply the result by 100.

Given that an island's peasant population is falling at a rate of 1.7% per year,

A 1.7% decrease means that 98.3% will remain.

as a result, decrease = 0.983/year

A(t) = A(original) multiplied by (0.983)^t

As a result, after 6 years, A(6) = 4600 x (0.983)6 = 4150

Answer:

The conclusion is incorrect because there is exactly one solution to the equation.

Step-by-step explanation:

8x - 12 = 4(12x - 6)

4 x 12x = 48x    4 x -6 = -24

8x - 12 = 48x - 24

Move the terms

8x - 12 - 48x = -24

Move the constant to the right-hand side and change its sign

8x - 48x = -24 + 12

-40x = -24 + 12

-40x = -12

Divide both sides by -40

40x  =  -12

40    =   40

The -value of the test is 1.90. This indicates that the mean processing time is significantly greater than 5.5 hours, supporting the manufacturer's desire to set a standard time required by employees to complete a certain process

The t-value will be equal to 1.39 for the given statistics.

To test if the mean processing time exceeds 5.5 hours, we can use a one-sample t-test.

The null hypothesis is that the mean processing time is less than or equal to 5.5 hours:

H0: µ ≤ 5.5

The alternative hypothesis is that the mean processing time is greater than 5.5 hours:

Ha: µ > 5.5

We will use a significance level of 0.05.

The formula for the t-test statistic is:

t = (X - µ) / (s / √n)

Where:

X = sample mean

µ = hypothesized population mean

s = sample standard deviation

n = sample size

Substituting the given values, we get:

t = (6 - 5.5) / (2 / √21) = 1.386

The degree of freedom for the t-test is n-1 = 20.

Using a t-table or calculator, the p-value associated with a t-value of 1.386 and 20 degrees of freedom is 0.093.

Since the p-value (0.093) is greater than the significance level (0.05), we fail to reject the null hypothesis. Therefore, there is not enough evidence to suggest that the mean processing time exceeds 5.5 hours.

-1 = -3 + c

-1 + 3 = c

2 = c

y = length of rectangle

A = area of rectangle = x*y = 1500000 [tex]ft^{2}[/tex]

L = length of fencing needed = 2(x + y) + x = 3x + 2y

L = 3x + 2([tex]\frac{1500000}{x}[/tex]) = 3x + 3([tex]10^{6}[/tex])[tex]x^{-1}[/tex]

1/5 or -1/9 would both be correct

Answer: 7

Step-by-step explanation:

The original equation is in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. A perpendicular line to Y = -4x + 7 would be Y = 4x + 7.

To find the equation of a line perpendicular to Y = -4x + 7, we need to switch the x and y variables and then change the sign of the slope.

The original equation is in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept.

Since the original equation has a slope of -4, the perpendicular line will have a slope of 4.

Therefore, the equation for the perpendicular line is y = 4x + b.

We can find the y-intercept by plugging in a point from the original equation.

For example, if we plug in (0,7), we get 7 = -4(0) + b, or b = 7.

Therefore, the equation for the perpendicular line is y = 4x + 7.

The closure property of addition states that the sum of two whole numbers will always be a whole number.

A whole number is a set of all positive integers from 0 to infinity.  Now we all know that if we add two positive numbers up, the sum will either remain constant (if the number is 0) or be greater than both numbers. This means that the sum of two whole numbers has to be a whole number.

Example 1 If we add 0 and 45

0 + 45

= 45

We already know that 45 is a whole number.

Example 2- If we add 486 and 354

486 + 354

= 840

From the definition, we can say that 840 is a whole number.
