Answer:

Step-by-step explanation:

To find the percentage of men who are over 70.5 inches tall, we need to use the standard normal distribution table, which gives the proportion of observations that fall within a given range of standard deviation from the mean.

We first need to standardize the height of 70.5 inches by subtracting the mean (68 inches) and dividing by the standard deviation (2.5 inches) to get (70.5 - 68) / 2.5 = 0.8

This tells us that 70.5 inches is 0.8 standard deviations above the mean.

We can then look up the proportion of observations that fall within this range in the standard normal distribution table, which is approximately 0.1587 or 15.87%. So, the answer is (1-0.1587) = 84.13 or 84.13%.

So the answer is 84.13%

If the two graphs are mirror images of one another across the line y = x, then they are inverse functions.[tex]$f(x)=\frac{x}{3}+10$ \\[/tex] and [tex]$g(x)=3 x-10$[/tex]

As for looking at the graphs, we already knew that. You should keep in mind that inverse functions are represented by two graphs that are mirror images of one another over the line y = x. The broadest definition of an inverse function is one that "reverses" another function.

The inverse, for instance, must take b to an if a function goes from a to b. When the first and second elements of each pair in the original function are switched, a set of ordered pairs is obtained that is known as the inverse of the function. The act of switching the x and y coordinates is known as obtaining an inverse. They aren't opposites. The output of the first function is sent through an inverse function, which then generates an output whose input was the first function.

So, option A) [tex]$f(x)=\frac{x}{3}+10$ \\[/tex] and [tex]$g(x)=3 x-10$[/tex] is the appropriate response.

The slope is 1.  It is the number before the x.  If we do not see a number, we assume that the number is 1.

Step-by-step explanation:

Answer:

The slope: 1

Step-by-step explanation:

The slope is simply the number in front of the x ONLY in the form y=mx+b, which it is currently in. If it is not in that form, try and manipulate the equation to put it into that form.

Moreover, if it is just x by itself imagine there being a 1 in front of it.

Answer:

x = 22.5°

3x = 67.5°

5x = 112.5°

7x = 157.5°

Step-by-step explanation:

You have both 2° and x for the measure of the first angle. I used x°.

Sum of the measures of the interior angles of a polygon

For an n-sided polygon:

(n - 2)180° = 2(180°) = 360°

x° + 3x° + 5x° + 7x° = 360°

16x = 360

x = 22.5°

3x = 67.5°

5x = 112.5°

7x = 157.5°

Probability of defect per blade = 1/500 = 0.002

Poisson distribution :

Pₓ (k) = (x ^k)/k × e⁻ˣ

Where k = The number of defective blades in a packet.

For a packet of 10 blades the mean number of defect x = 0.002 × 10 = 0.02

1.) When k = 0

Pₓ(0) = (0.02⁰ / 0!) × e - 0.02 = 0.980199

The approximate number of packets containing blades with no defective is :

10000 × 0.980199 = 9802

2.) When k = 1

Pₓ(1) = (0.02 / 1!) × e-0.02 = 0.019604

Approximate number containing one defective is :

10000 × 0.019604 = 196

3.) When k = 2

Pₓ(2) = (0.02² / 2!) × e - 0.02 = 0.000196

Approximate number containing 2 defective :

0.000196 × 10000 = 1.9 = 2

4.) When k = 3

Pₓ(3) = (0.02³ / 3!) × e-0.02 = 0.000013

Approximate number containing 3 defective is :

0.000013 × 10000 = 0.13 = 0

Answer:

no defective blades in a consignment of 1,00,000 packets is 99837.

Step-by-step explanation:

we first need to find the mean number of packets containing no defective blades. This mean is equal to the total number of packets (1,00,000) multiplied by the probability of a packet containing no defective blades.

The probability of a blade being defective is given as 0.002 (or 2/1000) or 2/100 or 1/50 or 2%.

Since a packet contains 10 blades. So the probability of a packet containing no defective blades is (1 - 0.002)^10 = 0.999936 or (1-0.02)^10 = 0.99837

So the mean number of packets containing no defective blades is (1,00,000 * 0.99837) = 99837

Step-by-step explanation:

The smaller square is 3' x 3' = 9 square feet.

The larger square is 9' x 9' = 81 square feet.

9 goes into 81 exactly 9 times (81 / 9 = 9), so we could just multiply the 54 cm by 9 and get your answer in centimetres.

54 x 9 = 486 cm

The number of groups of 5/3 are in 1 would be equal to 3/5

A fraction consisting of a quotient and remainder is a mixed fraction. we can convert the mixed fraction to improper fraction by first dividing the numerator by denominator and then taking the quotient as whole number and remainder as the numerator of proper fraction keeping the denominator same.

Division of fraction

Given that groups of 5/3 are in 1

= 1 ÷ 5/3

Then Multiply by the reciprocal of 5/3

The reciprocal of 5/3 is 3/5

For upcoming trip. Tim should hire company A

A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line. This is the reason why it is named as a 'linear equation'.

Given,

Distance to cover = 250 miles

For company A

By the graph line passes through

(200, 200) , (0,150)

equation of the line,

y-150 = [(200-150)/(200-0)](x-0)

y-150 = [50/200] x

y = x/4 + 150

y = 0.25 x + 150

No. of miles = 250

y = 0.25×250 + 150

y = 62.5 + 150

y = $212.5

Price for company B

y' = 0.75x + 50

where x is number of miles

for 250 miles price of company B

y' = 0.75 × 250 + 50

y' = 187.5 + 50

y' = $237.5

∵ y < y'

∴Price of trip with company A is less than company B

Hence, Tim should hire Company A for upcoming trip.

The sum of the exterior angles for a parallelogram is 360°.

Exterior angles are angles that are formed outside two lines when they intersect. They are located outside the two lines, on the outside of the shape. They can be found by adding the two interior angles together, whose measurements are always equal to 180 degrees. Exterior angles are also supplementary angles, meaning that the sum of their measurements is always equal to 360 degrees.

This is because the four angles on the outside of the parallelogram are all right angles, and the sum of four right angles is 360°.

Similarly, the sum of the exterior angles for a hexagon is also 360°.

This is because the six angles on the outside of the hexagon are all 120° angles, and the sum of six 120° angles is 360°.

In mathematics, place value refers to the relative importance of each digit in a number.

These locations begin at the unit's location (ones place).

The value of each digit in a number is known as place value. Every digit in a number has a distinct value depending on where it is located.

The value of a digit depends on its position in the number, which might result in a number having two comparable digits with distinct values.

Using place value diagrams, we can check that the digits are positioned correctly.

The right place for each digit in a number is shown on a place value chart. In order to precisely determine the positional values or worth of the various digits in a number, we must first write the.

The graph of the function f(x, y) = [tex]x^2[/tex] is a three-dimensional parabolic surface that opens upwards.

It is symmetric around the x-axis. This means that the shape of the surface is the same on both the positive and negative x-values. It is also a concave-up function, which means the graph is curved upwards.

Its vertex is located at the origin (0,0) and the equation of the parabola is y =[tex]x^2[/tex]. This means that the x-values of the graph can be any real number, while the y-values will always be non-negative as the square of any real number is always non-negative.

As x-values increase or decrease, the y-values will also increase, resulting in a smooth and continuous surface. Overall, the graph represents the upward parabolic shape of x squared.

b. The function (f + g)(5) = 36

c. (f + g)(5) = 36 means in 5 months, the total number of animals adopted at the two shelters is 36.

We can evaluate functions just as we solve normal algebraic equations when we plug in the given value of a variable.

Given the following:

f(x) = 4x + 9 [number of animals at one shelter]

g(x) = x + 2 [number of animals at another shelter

Part A: Find (f + g)(x)

(f + g)(x) = f(x) + g(x) = 4x + 9 + x + 2

Combine like terms:

(f + g)(x) = 5x + 11

Part B: Find (f + g)(5)

Substitute the x = 5 into the function (f + g)(x)

(f + g)(5) = 5(5) + 11

(f + g)(5) = 25 + 11

(f + g)(5) = 36
