Answer:

80 years

Step-by-step explanation:

Let daughter's age be x years.

Therefore, women's age = 10x years

8 years after:

Daughter's age = (x + 8) years

Women's age = 4(x + 8) years

4(x + 8) = (x + 8) \\ 4x + 32 = x + 8 \\ 4x - x8 - 32 \\ 3x =  - 24 \\ x =  \frac{ - 24}{3}  \\ x =  - 8 \\  \because \: age \: of \: a \: person \: can \: not \: be \: negative \\  \therefore \: x = 8 \\ \therefore \: 10x = 10 \times 8  \\  \huge  \red{ \boxed{\therefore \: 10x  = 80 \: years}}

daser333 [38]

Answer:

You can make 9 three Digit numbers

Step-by-step explanation:

The 9 three digit numbers are:

257

275

752

725

527

572

This can also be easily found out by multiplying the number of digits to the number of digits needed for the number, in this case, there are 3 digits, and the number must have 3 digits in them (without them repeating).

3 digits x 3 needed for the numbers  = 9 three digit numbers

Shkiper50 [21]

Outcome Bag of Gold Magic Wand

Relative frequency 0.32 0.68

The relative frequency of getting a bag of gold is .......... reasonably close

.32 is close to 30% so

Alison's claim about the theoretical probability is likely to be 2............true

Further, this means that the theoretical probability of getting a magic wand is most likely 3............1 - 30% = 70%
