The scale factor of area of the drawing to the area of the office is the

square of the scale factor of the length of the drawing.

Reasons:

The given parameters are;

1 inch in the scale drawing = 4 yd. in actual dimension

4 yd. = 144 inches

Therefore;

1 inch in the scale drawing = 144 inches in actual dimension

The scale factor of  length of the drawing, s = 1:144

The scale factor of area = s²

Therefore, we have;

Therefore, we have;

Where;

A = The actual office space area

There fore;

12 × 144² = A × 1²

A = 12 × 144² = 248,832 in.²

1 yd.² = 1,296 in.²

The area of the office space is 192 square yards.

Using the z-distribution, it is found that 217 sample measurements should be taken at each site.

The margin of error of a z-confidence interval is given by:

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

In which:

The first step is finding the critical value, which is z with a p-value of [tex]\frac{1 + \alpha}{2}[/tex], in which [tex]\alpha[/tex] is the confidence level.

In this problem, [tex]\alpha = 0.95[/tex], thus, z with a p-value of [tex]\frac{1 + 0.95}{2} = 0.975[/tex], which means that it is z = 1.96.

Estimate of the standard deviation of 1.5, thus, [tex]\sigma = 1.5[/tex].

We want the sample for a margin of error of 0.2ºC, thus, we have to solve for n when [tex]M = 0.2[/tex].

[tex]M = z\frac{\sigma}{\sqrt{n}}[/tex]

[tex]0.2 = 1.96\frac{1.5}{\sqrt{n}}[/tex]

[tex]0.2\sqrt{n} = 1.96(1.5)[/tex]

[tex]\sqrt{n} = \frac{1.96(1.5)}{0.2}[/tex]

[tex](\sqrt{n})^2 = (\frac{1.96(1.5)}{0.2})^2[/tex]

[tex]n = 216.1[/tex]

Rounding up:

217 sample measurements should be taken at each site.

Answer:

2 prime factors

Answer: 2 prime factors

Step-by-step explanation:  A semiprime is a number n that has just 2 prime factors p and q so n = p × q. It is therefore "almost" a prime (which has only one prime factor, itself!) or a semiprime.

-(38/21)

that is the answer

Answer:

-38/21, or 1 17/21

Step-by-step explanation:

To add, we need to change the denominators to be the same. The least common denominator is 21. -8/7 is equal -24/21, and -2/3 is equal to -14/21. If we add these we get -38/21, or 1 17/21.

Answer:

  (d)  y = 2×7^x

Step-by-step explanation:

If you try x=2 in each of the expressions, you find only one of the gives 98 as the value.

  a) 14^2 = 196

  b) 7×2^2 = 28

  c) 2^(7×2) = 2^14 = 16,384

  d) 2×7^2 = 2×49 = 98 . . . . . . . correct answer choice

__

Alternatively, you can recognize that the x-values in the given (x, y) pairs differ by 1, so the ratio of y-values will be the base of the exponential term:

  98/14 = 7

so you're looking for something of the form 7^x. That would be ...

  y = 2×7^x

__

In more general terms, consider

  y = ab^x

If you have x=1 and x=2, then this will be ...

  y1 = ab^1 = ab

  y2 = ab^2

Dividing the second by the first gives ...

  y2/y1 = (ab^2)/(ab) = b . . . . . . . general solution when x-values differ by 1

  98/14 = b = 7

From the x=1 case, we have ...

  14 = 7a   ⇒   a = 2

  y = 2·7^x

The domain of function H(t) is 0 ≤ t ≤ 20.

A function has an input and an output.

A function can be one-to-one or onto one.

It simply indicated the relationships between the input and the output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

From the graph,

We see that the value of t is from 0 to 20 seconds.

Now,

The value of t can be written as an inequality:

0 ≤ t ≤ 20

Thus,

The domain of function H(t) is 0 ≤ t ≤ 20.

The Volume of Cylinder is 1271.7 in³.

The volume of a cylinder is the amount of space that it occupies. It is a measure of the total capacity or content enclosed by the cylindrical shape.

The formula for calculating the volume of a cylinder is:

Volume = πr²h

We have, Radius= 5 in

Height= 9 inch

So, the Volume of Cylinder

= πr²h

= 3.14 x 5 x 5 x 9

= 3.14 x 5 x 81

= 3.14 x 405

= 1271.7 in³

Thus, the Volume of Cylinder is 1271.7 in³.

Step-by-step explanation:

deez nuuuuuuuts

If 1 share had an initial cost of $0.000007, then 3,000,000 shares would be worth

(3,000,000 shares) × ($0.000007/share) = $21

If the price increases to $0.01 per share, then the same number of shares would have a value of

(3,000,000 shares) × ($0.01/share) = $30,000

So you've gained a net profit of $30,000 - $21 = $29,979, which corresponds to a

$29,979 / $21 = 1,427.57 = 142,757%

Answer:

  y = 1/5

Step-by-step explanation:

Divide both sides of the equation by the coefficient of the variable.

  7 = 35y

  7/35 = (35y/35)

  1/5 = 1y

  y = 1/5

_____

A number divided by itself is 1. A number multiplied by 1 is unchanged.

To get from 35y to 1y, or y, divide by 35. That gives you (35/35)y = 1y = y.

Whatever you do to one side of the equation must also be done to the other side. Dividing 7 by 35 gives 7/35 = (7/7)×(1/5) = 1/5.
