Answer:

c and d

Step-by-step explanation:

Simplify a: 6x+7=4x+7 ~ No matter what, this cannot be possible

Simplify b: 6x=4x ~ Once again, this is impossible unless x=0, but I'll assume it can't be for now

Simplify c: 4x+7=4x+7 ~ This clearly is a correct statement, this it is c

Simplify d: 6x-1=4x+1 ~ By subtracting 4x on each side, then adding 1 on both sides, we get 2x=2, so x can be 2.

Answer:

a) $s= 9.74$

D. 9.74

b) $Median= 74$

B. 74

Step-by-step explanation:

Part a

We have the following dataset given:

69 74 75 62 70 93 64 69 61 88 67 77 87 90 66 91 77 63 82 82 71 74 76 65 83

We can begin calculating the sample mean with the following formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

And replacing we got:

$\bar X = 75.04$

Now we can calculate the sample deviation with the following formula:

$s =\sqrt{\frac{\sum_{i=1}^n (X_i-\bar X)^2}{n-1}}$

And after replace we got:

$s= 9.74$

Part b

For this case we need to sort the value on increasing way:

[1] 61 62 63 64 65 66 67 69 69 70 71 74 74 75 76 77 77 82 82 83 87 88 90 91 93

And the median would be the value in the position 13 and we got:

$Median= 74$

F(x) = 4x + 7, g(x) = 3x2<br><br> Find (fg)(x).

Brums [2.3K]

F(x) = 4x + 7
g(x) = 3x²

(f · g)(x) = 3x²(4x + 7)
(f · g)(x) = 3x²(4x) + 3x²(7)
(f · g)(x) = 12x³ + 21x²
