On a sketch of a mural,3 inches represents one foot in the mural. A door in the sketch is 2 inches wide by 5 inches high. What i
grandymaker [24]

Answer:

Length of the door,                  <em> l</em> = 5 inches (<em>in</em>)

Width or Breadth of the door, <em>w</em> = 2 inches (<em>in</em>)

Perimeter                                   p = 2(l + w)

                                                   = 2( 5 + 2) <em>inches</em>

<em>                                                    = 2(5) inches + 2(4) inches</em>

                                                   = 10 <em>inches</em>  + 4 <em>inches</em>

                                                   = 14 <em>inches</em> or 14 <em>in</em>

  Step-by-step explanation:

The perimeter of a plane shape is the measurement of the length of its outside boundary, which means the distance around its edges.

The door in the sketch is the shape of a rectangle. the distance around the edge of the door is the sum of all the sides. The longer side of a rectangle is called the length and it is usually represented by letter<em> l</em> while the shorter side is known as width or breadth represented by letter <em>w</em> and<em> b </em>respectively. The perimeter is calculated by the formula 2(l + w). where l means the length and w represents the width.

As an aid to the establishment of personnel requirements, the director of a hospital wishes to estimate the mean number of peopl
erma4kov [3.2K]

Answer: 24.9793

Step-by-step explanation:

Given : The director randomly selects 64 different 24-hour periods and determines the number of admissions for each.

For this sample, he calculated a mean  \overlien{x}=396 and a standard deviation of 100.

The 95% confidence interval results in an interval of 396 \pm 24.9793

We know that the confidence interval for population mean is given by :_

\overlien{x}\pm E, where E is the margin of error.

By comparing this to the given interval , we find that the margin of error = 24.9793

Solve the inequality<br> 7+7(x+4)&gt;21
Kryger [21]

Answer:

x>-2

Step-by-step explanation:

Hi there!

We are given the inequality 7+7(x+4)>21, and we want to solve it

Solving an inequality is a lot like solving an equation; we want to isolate x on one side by itself.

So to start, we'll preform the distributive property on 7(x+4) (multiply x by 7, then multiply 4 by 7 and add those two together).

7+7x+28>21

Now combine like terms.

7x+35>21

Subtract 35 from both sides

7x>-14

Divide both sides by 7

x>-2

Hope this helps!

5+(−4)+(−7)+2 jijujuijuijuijujijuijuijuijiji
Maurinko [17]

Combine the terms. Note that: one positive and one negative sign results in a negative sign.

Simplify: 5 + (-4) = 5 - 4 = 1

1 + (-7) = 1 - 7 = -6

-6 + 2 = -4

-4 is your answer
