Answer:

C. 1/25

Step-by-step explanation:

I assume this is a fair spinner and the probability of landing in all colors is equal.

First spin:

p(purple) = 1/5

Second spin:

p(purple) = 1/5

The two spins are independent events, so the probability of landing on purple twice is the product of the two individual probabilities.

p(purple and purple) = 1/5 * 1/5 = 1/25

The Table below is a data set that lists how many pairs of shoes are owned by some of your classmates.

Pani-rosa [81]

Answer:

7.5

Step-by-step explanation:

To find the median, first order the numbers from least to greatest:

2, 4, 5, 7, 8, 8, 10, 12

Then, find the middle number (number in the middle):

There are 2 middle numbers. 7 and 8.

Because there are 2 numbers, we need to find the average. If there was only one number, that would be the median.

To find the average, add 7 and 8. Then, divide the sum by 2 because there are 2 numbers;

7 + 8 = 15

15 / 2 = 7.5

Have a nice day!

Justin is 2 years older than one third marcellas age. aimee is four years younger then 2 times Justins age.Define a variable and

dimaraw [331]

J=justin
marcella=m
aimee=a

j is 2 older than 1/3 of m
'of' means multiply
j=2+1/3m

a is 4 younger than 2 times j
a=-4+2j

represent justin's age?
dunno

ok so I can solve if I know m=63
j=2+1/3m
j=2+1/3(63)
j=2+21
j=23
subsitute
a=-4+2j
a=-4+2(23)
a=-4+46
a=42

justin is 23 and aimee is 42 if marcella is 63

Degger [83]

Answer:

75%

Step-by-step explanation:

To know the answer, you should take into account that, 70 equals 1,75 times 40.

This is because $\frac{70}{40}=1,75$ .

Then, if 70 equals 1,75 times 40, it is 0,75 = 75% greater than 40.
