Explain why the HCF of 81 and 154 must be 1.

Answers

Answer 1

the HCF of the numbers 81 and 154 must be 1.

HCF means the highest common factor that the two numbers have between them. When the numbers are divided by HCF, they become composite numbers. It is the greatest common divisor of two or more integers, which are not all zero, is the largest positive integer that divides each of the integers.

We are given two numbers:

81 and 154

We know that 81 is:

81 = 3 × 3 × 3 × 3

And 154 is:

154 = 2 × 7 × 11

We can see that both the numbers do not have any factor in common.

So, the highest common factor that is the HCF can be 1 only.

Therefore, the HCF of the numbers 81 and 154 must be 1.

Problem 2: A storm causes a 14m hydro pole to lean over. The pole leans at an angle of 72° to
the ground. How high is the top of the pole from the ground?

Answers

The top of the pole from the ground is 13.314798.

Given condition, formulate :

= 14 * sin (72°)

= 4 sin 72°

= 14 * 0.951057

= 13.314798

The study of angles and of the angular relationships of planar and three-dimensional figures is known as trigonometry. The trigonometric functions (also called the circular functions) comprising trigonometry are the cosecant, cosine , cotangent , secant , sine , and tangent .

The trigonometric function can be described as being even or odd.

Odd trigonometric functions: A trigonometric function is said to be an odd function if f(-x) = -f(x) and symmetric with respect to the origin.

Even trigonometric functions: A trigonometric function is said to be an even function, if f(-x) = f(x) and symmetric to the y-axis.

Hence, the top of the pole from the ground is 13.314798.

Use algebraic methods to prove that the given function has an x-intercept that is equal to its y-intercept. In your final
answer, include all of your calculations.
y= x/x^2-1

Answers

Step-by-step explanation:

the y-intercept is the y value when x = 0.

the x-intercept is the x value when y = 0.

for x = 0

y = 0 / (0² - 1) = 0/-1 = 0

this automatically answers also our question about the x value when y = 0. we found this out already with the y-intercept.

the interception point with both coordinate axis is (0, 0).

To test the ability of mechanics to identify simple engine problems, a car with a single such problem was taken in turn to 72 different car repair facilities. Only 42 of the 72 mechanics who worked on the car correctly identified the problem. Does this strongly indicate that the true proportion of mechanics who could identify this problem is less than 0.75?


a) Perform the appropriate test of hypothesis using = 0.01. Clearly show the eight (8) steps

Answers

Using the z-distribution, it is found that since the p-value is less than 0.01, there is strong indication that the true proportion of mechanics who could identify this problem is less than 0.75.

What are the hypotheses tested?

At the null hypotheses, it is tested if there is not enough evidence that the proportion is less than 0.75, that is:

[tex]H_0: p \geq 0.75[/tex]

At the alternative hypotheses, it is tested if there is enough evidence that the proportion is less than 0.75, that is:

[tex]H_1: p < 0.75[/tex]

What is the test statistic?

The test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

In which:

[tex]\overline{p}[/tex] is the sample proportion.p is the proportion tested at the null hypothesis.n is the sample size.

For this problem, the parameters are given as follows:

[tex]n = 72, \overline{p} = \frac{42}{72} = 0.5833, p = 0.75[/tex]

Hence the test statistic is given by:

[tex]z = \frac{\overline{p} - p}{\sqrt{\frac{p(1-p)}{n}}}[/tex]

[tex]z = \frac{0.5833 - 0.75}{\sqrt{\frac{0.75(0.25)}{72}}}[/tex]

z = -3.27.

What is the p-value of the test?

Considering a left-tailed test, as we are testing if the proportion is less than a value, with z = -3.27, the p-value is < 0.01.

Since the p-value is less than 0.01, there is strong indication that the true proportion of mechanics who could identify this problem is less than 0.75.

Write the equation of the line that passes through the points (1,1) and (11,−2).

Answers

The equation of the line in slope-intercept form is: y = -3/10x + 13/10.

How to Write the Equation of the Line?

Given the points, (1,1) and (11,−2). Follow the steps explained below.

Step 1: Find the slope of the line:

Slope (m) = change in y / change in x = (-2 - 1)/(11 - 1)

Slope (m) = -3/10

Step 2: Substitute m = -3/10 and (a, b) = (1, 1) into y = mx + b to find the value of b

1 = -3/10(1) + b

1 = -3/10 + b

1 + 3/10 = b

b = 13/10

Step 3: Substitute m = -3/10 and b = 13/10 into y = mx + b

y = -3/10x + 13/10

Thus, the equation of the line in slope-intercept form is: y = -3/10x + 13/10.

An accounting machine operator wanted to divide a 65 minute job between two identical machines so that one machine would take one and a half times as long as the other. How much time was taken by the machine doing the longer job?

Answers

The slow machine did the job is 39 minutes as calculated with the help of a linear equation in one variable.

A linear equation in one variable is given by the combination of the variable with constants and coefficients such that a unique relationship is established between the terms.

Let us consider the faster machine takes x minutes the finish the job.

Hence the slower machine will take one and a half times .

∴ slower machine takes 1.5 x minutes.

Total time taken by the two machines = x + 1.5x = 2.5 x

But together the two machines will take 65 minutes to complete the job .

So now we form a linear equation with the variable x to solve for the value of x

∴ 2.5 x = 65

or, x = 65 ÷ 2.5

or, x = 26 minutes

Therefore the faster machine takes 26 minutes.

Hence the slower machine will take 1.5 x = 1.5 × 26 = 39 minutes.

Answers

All calculations for answer in picture form

Answer:

There are 88 square inches needed to cover a box that is 4 in • 6 in • 2 in

Step-by-step explanation:

In order to cover the box you need to find the surface area of it. The formula for finding the surface area of a rectangular prism is 2 ((wl) + (hl) + (hw)). The dimensions of the box is 4 inches in length, 6 inches in width, and 2 inches in height.

Apply the dimensions into the formula of the rectangular prism when the numbers are plugged in it results in 2 ( (64) + (24) + (26) )Multiply the dimensions the area of length• width is 24 (six times four is twenty-four), the area of height•width is 8 (two times four is eight), and the area of height•width is 12 (two times six is twelve). At the end of this step it becomes 2 ((24) + (8) + (12))Add all the numbers inside the parentheses then it becomes 2 (44) Multiply the number in parentheses by 2 the final answer is 88 in²
