Answer:

here's the steps

Step-by-step explanation:

first, you need to get x by itself.In order to do that you need to do the opposite to the other side. ex: x5= 1/10; what you would do is divide 1/10 by 5 to get x = 0.5 , 5/10

Suppose that a customer service center claims that the telephone calls it receives last 112 seconds on average, with a standard

adoni [48]

Answer:

95% Confidence interval: (111.02,112.98)

Step-by-step explanation:

Average = 112 seconds

Standard Deviation = 9 seconds

n = 324

Confidence interval:

$\mu \pm z_{critical}\frac{\sigma}{\sqrt{n}}$

Putting the values, we get,

$z_{critical}\text{ at}~\alpha_{0.05} = \pm 1.96$

$112 \pm 1.96(\frac{9}{\sqrt{324}} ) = 112 \pm 0.98 = (111.02,112.98)$

Solve the inequality using the Distributive Property. -4(y-6) ≤ (-9+y)(-2)

iragen [17]

Answer:

3 ≤ y

Step-by-step explanation:

-4(y-6) ≤ (-9+y)(-2)

Distribute

-4y +24 ≤ 18 -2y

Add 4y to each side

-4y+4y +24 ≤ 18 -2y+4y

24≤ 18 +2y

Subtract 18 from each side

24-18≤ 18-18 +2y

6 ≤ 2y

Divide by 2

6/2≤ 2y/2

3 ≤ y

Name the following in the figure shown below: The base or bases, The part labeled PQ, and the figure itself

zmey [24]

Take a look at it. We know it's a cone, right? So that answers your 3rd question. The base (or the part that it sits on if you put it down), is a circle. The other parts it can't sit on without rolling, so it has to be that circular side. And if that's a circle, that means that any line from the center to the outside 'circumference' is the radius. This means that the answer is A.

Jasmine has painted two of her bedroom walls. She wants to put decorative trim around the perimeter of the walls and around the

ICE Princess25 [194]

Given the data below, the total length or amount of decorative trim can be calculated. It can be said that the total length of decorative trim is equal to the total perimeter of the two walls, the window, and the door, minus the base of the door.

Wall 1 = 2(8) + 2(18) = 52 ft.
Wall 2 = 2(8) + 2(15) = 46 ft.
Window = 2(3) + 2(6) = 18 ft.
Door = 2(7) + 5 = 19 ft.

Total length = 52+46+18+19 = 135 ft. of decorative trim
