Work out the probability it is a humbug.

The probability of an eclair is 1/15, which means for every 1 eclair there is a total of 15 sweets.

Since the table says there is 3 eclairs, there is 3 x 15 = 45 total sweets.

Now add the 3 different sweets together to equal 45:

3 + 2x+6 + x = 45

Combine like terms:

3x +9 = 45

Subtract 9 from each side:

3x = 36

Divide each side by 3:

X = 36 /3

x = 12

Now you have x, calculate the number of humbugs:

2x +6 = 2(12) +6 = 24 + 6 = 30 total humbugs.

The probability of picking one would be 30/45, which reduces to 2/3.

3.how is solving radical equations different than solving linear equations?

step-by-step explanation:

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
