Answer:
3.97 x 10⁸
Step-by-step explanation:
Answer:
4| 7
5| 2 7 8 8
6| 1 6 6 8 8
7| 0 2 2 3 3 5 6 7
8| 4 4 4 5 6 6 7 9
9| 0 1 1 2 3 7
And with the notation 4|7 represent 47
Step-by-step explanation:
For this case we have the following dataset given:
58 52 68 86 72 66 97 89 84 91 91 92 66 68 87 86 73 61 70 75 72 73 85 84 90 57 77 76 84 93 58 47
And if we order the dataset in increasing way we got:
47 52 57 58 58 61 66 66 68 68 70 72 72 73 73 75 76 77 84 84 84 85 86 86 87 89 90 91 91 92 93 97
And if we create the stem plot we got:
4| 7
5| 2 7 8 8
6| 1 6 6 8 8
7| 0 2 2 3 3 5 6 7
8| 4 4 4 5 6 6 7 9
9| 0 1 1 2 3 7
And with the notation 4|7 represent 47
Answer:
2
Step-by-step explanation:
because it is 2 parts white paint one part blue paint
You would set up a proportion for people that choose beach/ total
So (14+17+19)/(50+50+50) which simplifies to 50/150 or 1/3
From here we can set 1/3 = x/1200 and solve for x
To do this we would multiply each side by 1200 to isolate x
(1/3)×1200= 400
So x=400
Therefore, 400 people can be expected to pick the beach
The real part of the result is the product of the real parts of the factors and the product of the imaginary parts:
a = 15*6 - (-4)(-3) = 90 -12 = 78
_____
You can treat this the same as any other product of binomials except that i² = -1.
... (15 -4i)(6 -3i) = 15(6 -3i) -4i(6 -3i) = 15·6 -15·3i -4·6i +4·3i²
... = 90 -45i -24i +12i² = (90 -12) -69i = 78 -69i
