6x2 + 12x + 2 = -10 Quadratic equation solve

1 answer:

7 0

Add 10 on both sides

6x^2+12x+12=0.

Divide by 6 on both sides.

X^2+2x+2=0

Plug into quadratic formula

X=(-2 +\- (2^2-4•1•2))^1/2) /2•1
X=(-2 +\- (-4)^1/2)/2
X=(-2+\- 2i) /2
X=-1+\- I
X= -1 + i OR -1 - i

Solve for t.

wlad13 [49]

One solution was found : t ≤ -13 (number 4)

Pull out like factors :

-3t - 39 = -3 • (t + 13)

Divide both sides by -3

Remember to flip the inequality sign:

Solve Basic Inequality :

Subtract 13 from both sides to get t≤−13

What is the mean, median and mode of the following data set? Please label each response.

kumpel [21]

The mean is the average value of numbers given in the series

The median is the middle value of the given series

The mode is the number that is appears more than any other number given in the series

Step-by-step explanation:

The given series is 31,1,27,23,15,27,25,18,22 (totally 9 numbers)

let us change them in a ascending order like 1,15,18,22,23,25,27,27,31

$Mean = (1+15+18+22+23+25+27+27+31)/9 = 189/9 = 21$

Mean = 21

Median = middle value of the series 1,15,18,22,23,25,27,27,31

23 is the median

Mode = 27 ( it appears in two times 1,15,18,22,23,25,27,27,31)

final answer is

Mean = 21

Median = 23 and

Mode = 27
