What is the area??????
Westkost [7]
Your answer would be 91.1 units².
We can split this shape into a trapezium and a semicircle, and then find the area of both and add them.
To find the area of a trapezium, the formula is
(a + b)/2 × h, which means we do 14 (the length of AD) + 8 (the length of BC) = 22, and 22/2 = 11. Then we multiply 11 by the height of the trapezium, which is 6 because 10 - 4 = 6. This gives us the area of the trapezium as 66 units².
To find the area of a semicircle, the formula is πr²/2, and the radius is 4 because the diameter is 8 (16 - 8 = 8). This means we do π4²/2 = 16π\2 = 8π = 25.13.
Then we need to add together 66 and 25.13, which equals 91.13, or 91.1 to the nearest tenth.
I hope this helps!

Apple launches an ad campaign for iPhone 12. Managers want to know what is the % of social media mentions that have positive rea
Orlov [11]

Answer:

social media mentions do managers at Apple need to collect, if they want to get a margin of error of 2%

Sample size 'n' = 625

Step-by-step explanation:

<u><em>Step(i)</em></u>:-

Given data Apple launches an ad campaign for iPhone 12

Managers want to know what is the % of social media mentions that have positive reactions to the new ad campaign

probability of positive reactions p = 1/2

Probability of negative reactions q = 1-p = 1/2

we know that \sqrt{p(1-p}\leq \frac{1}{2}

<u><em>Step(ii):</em></u>-

Given margin of error  = 2 % =0.02

The margin of error is determined by

          M.E = \frac{\sqrt{p(1-p} }{\sqrt{n} }

         0.02 = \frac{\frac{1}{2}  }{\sqrt{n} }

        \sqrt{n} =\frac{1}{2 X0.02}

        √n = 25

squaring on both sides, we get

       n = 625

Write an equation for each exponential function in the form y=abₓ (to the xth power)
GuDViN [60]

Answer:

y = 2 * 9 ^ x

Step-by-step explanation:

From the first point, you can get the value of a, since any number with power 0 with always equal to 1

  • 2 = a(1)
  • a = 2

Now you have y = (2)(b ^x), use the second point, substitute the value of X and y to (3,1458) to get the B value.

  • 1458 = 2b ^ 3
  • 729 = b ^ 3
  • B = 9
