Answer:
the given expression is equivalent to the 
Step-by-step explanation:
The computation is shown below:

Now applied the exponent rule i.e. presented below:



Hence, the given expression is equivalent to the 
Answer:
-105
Step-by-step explanation:
a negative times a negative makes it positive so -15(7) which would just equal -105
Answer:
Step-by-step explanation:
Given that in an experiment, a number cube is rolled 4 times. The number of times a 5 shows is recorded. Sixty trials of the experiment are run.
No of 5's Freq Prob
0 6 0.1
1 9 0.15
0 33 0.55
3 3 0.05
4 9 0.15
60 1
The above is the probability distribution of the discrete variable.
I believe it's D) Division
35/7=5
5/5=1 (same as x)
Hope this helps!
