1. 2x2 (3+8)
I need the answer

Answers

Answer 1
Answer:

Answer:

the answer is 44

Step-by-step explanation:

Because (3+8) is in paranthesis, you should do this first: 2x2(11)

Now, because there is no sign between the second 2 and the parantheses, this simply means they are multiplied so now you have: 2x2x11

Now, because they all have the same sign, you can just multiply across:

2x2x11 = 44

What is the solution to x+5>-7

Answers

According to the given data we have the following inequality:

x+5>-7

To find the solution of the inequality above we would make the following:

\begin{gathered} \mathrm{Subtract\: }5\mathrm{\: from\: both\: sides} \n x+5-5>-7-5 \end{gathered}\begin{gathered} \text{Finally, simplify},\text{ and so:} \n x>-12 \end{gathered}

Therefore, the solution to x+5>-7​ would be x>-12

Find the length of AB.

Answer:

  21.5 cm

Step-by-step explanation:

Consider rectangle PQRS. Its area is ...

  A = LW

  90 cm² = PQ×QR = PQ×(20 cm)

  (90 cm²)/(20 cm) = PQ = 4.5 cm . . . . . . BC has this value, too

__

Consider the perimeter of ABCD. It is given by ...

  P = 2(L +W)

  52 cm = 2(AB +BC) . . . . substitute known value for P

  26 cm = AB +4.5 cm . . . . use known value for BC, divide by 2

  21.5 cm = AB

0.7 is the correct number:)

You flip a fair coin 10,000 times. Approximate the probability thatthe difference between the number of heads and the number of tails is at most 100.

Answers

Answer:

E[X] = (np) (p+(1-p))^(n-1)

With n =10,000 and p=0.50 we get

E[X]= (10,000*0.50) (0.50+(1–0.50))^(10,000–1)

E[X] = 5,000(1)

So assuming the coin is fair (p=50%), then we can expect to get heads 5,000 times when the coin is tossed 10,000 times.

The following is a list of 5 measurements. 20,10,13,11,20 Suppose that these 5 measurements are respectively labeled.

Answers

Answer:

1190

Step-by-step explanation:

Here, you need to add the squares of the measurements.

20² + 10² + 13² + 11² + 20² =

= 400 + 100 + 169 + 121 + 400

= 1190
yeah it would be 1190

I NEED YOUR HELP 22 POINTSA cone has a base of 30 in^2 and a height of 8.8 what is the volume of the cone?
Plz show how to do it I'm stuck

Answers

Hello from MrBillDoesMath!

Answer:

88 in^3

Discussion:

The volume of a cone of height h and base radius r is

          Pi * R^2 * (h/3)

But Pi * r^2 ( = 30) is the area of the base so the volume is:

         (30) * (8.8)/3 =

         (30/3) ( 8.8) =

         10 * 8.8 =

         88 in^3
