Two parallel lines are cut by a transversal. What is the measure of 1​

Both lines are parallel so using the bottom line you are given angle 7 as being 80 degrees. Angle 5 and 7 form a straight line which is 180 degrees so angle 5 would be 180-80 = 100 degrees.

Angle 1 is the same as angle 5 so angle 1 is 100 degrees.

100 degrees

B. 100°

Step-by-step explanation:

Angles 1 and 5 are corresponding angles and congruent.

Angles 5 and 7 are a linear pair and supplementary angles, so their measures add to 180°.

m<5 + m<7 = 180°

m<5 + 80° = 180°

m<5 = 100°

m>1 = m<5

m<1 = 100°

its 4 because 2 times 2 is 4, if you double the number two you get four

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560
