(PLEASE HELP)

Pepsi [2]

Answer:

$x = 54$

$y = 0.225$

Detailed steps:

We know that the number of total events is

$n = 80$

and that the probability of a certain event E (for example, "<em>the enemy drops two objects</em>") is computed as the number of times event E occurred, divided by the total of events N=80.

Then:

$0.675 = \frac{x}{80}$

$x = 80 \times 0.675 = 54$

and

$y = \frac{18}{80} = 0.225$

We can verify by checking that adding all probabilities sums up to one.

Angle(<)K and <L are complementary angles. If m<K = 3x+3 and m<L = 10x-4, find the measures of both angles.

Len [333]

3x+3 + 10x-4 +90 (because complementary angle add up to 90)

13x-1+90 (add 1)

13x/13=91 (divide 13 on both sides)

x=7

now you fill in 7 for x

m<K=24 and m<L=66

hope i helped
