For this one, use the order of operations to solve it, we called it PERMDAS to remember the steps.

14-6.2 times (-3+ -7)

So do the parenthesis first

-3+-7= -10

now the multiplication

-6.2 times -10= 62

a negative times a negative equal a 62

Now your problem is 14-62

Which equals -48.

So if I did my math and operations correctly, the answer would be B. -48.


Hope this helps!

<span>Here, we first calculate the value of 't' and then go on calculating the probability that the t-value is more than calculated t-value, given the degree of freedom (d.f. = n-1). t.calc = (77-76)/(5/sqrt(100)) = 1/(1/2) = 2 P(x > 77) = P(t > 2, d.f. =99) = 0.0241= 2.41%</span>
