1) Billy walks 15 miles every day to soccer practice, and catches a ride home from his grandma. Billy had 5 practices last week.

1 ) Billy walks 15 miles every day to soccer practice and he had 5 practices last week.

We know that, 1 mile = 1760 yards

So, 15 miles = (15× 1760) yards = 26400 yards

Thus the total distance walked in 5 practices will be: $(26400*5)yards = 132000 yards$

2) Mark's current age is $t$ years

So, his age was in 10 years ago $=(t-10)years$

Given that, his current age is 3 times his age 10 years ago.

So, the equation to represent this situation will be : $t= 3(t-10)$

Determine whether the following problem involves a permutation or a combination and explain your answer. How many different -le

Alex_Xolod [135]

Answer:

B. The problem involves a combination because the order in which the letters are selected does not matter.

Step-by-step explanation:

Computation technique is a method of statistics to find possible ways of combination. In computation technique it is assumed that order does not matter and letters will be selected at random. Permutation is a statistics technique to find possible ways of combination when the order does matter. Permutation technique cannot be used when order does not matter.
