<span>Evaluate the expression 5a + 5b. Let a = -6 and b = -5.
n = 5a + 5b
n = 5(-6) + 5(-5)
n = -30 + -25
n = -55

Answer:
1000 runners
Step-by-step explanation:
Take total number of runners to be -----------x
90% of x managed to complete the marathon= 90/100 × x =0.9x
30% of those who completed the marathon were men= 30% × 0.9x
=0.3×0.9x= 0.27x
=270 men completed the marathon; this means
0.27x=270--------------------------------find x by dividing both sides by 0.27
x= 270/0.27
x=1000 runners

Step-by-step explanation:
According to the provider, this same width of that same confidence interval would be as follows:
= 
= 
Depending on the input observed, the width including its confidence interval would be as follows:
= 
= 
As even the width of that interval again for survey asserted > the width including its confidence interval according to the provider's statement, we could conclude that such is the appropriate reaction.
