Table 2

Find the following from given Table 2
i) Arithmetic Mean ii) Median Cost iii) Q1 & D4 iv) 25th & 46th Percentile

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)

plug in the numbers into the variables

your answer is a

6x = 48

i hope this . 6 cards each and a total of $48. dvide each side by 6 and you will have your answer.

step-by-step explanation:

given expression is .

now we need to simplify the given expression .

we know that square root is equivalent to the power 1/2. so that means we can take half of the exponents to get the square root of given expression.

expanding that will give a very very large number so let's keep answer in exponent form.

divide the numbers
