Step-by-step explanation: The two angles are not equal. The alternate interior angles theorem states that if the alternate interior angles are equal when a pair of lines is cut by a transversal, the two lines are parallel. However, the two angles are not parallel, so the lines are not parallel.

If anyone knows the answer to this can you help me

Murljashka [212]

Answer:

Step-by-step explanation:

The equation of a line is:

y - y₀ = m(x - x₀)

where m is the slope and (x₀, y₀) is the point which the line passes through

The product of slopes of two perpendicular lines is -1

so if given lines slope is ¹/₇ them:

¹/₇·m = -1

m = -7

(3, -7) ⇒ x₀ = 3, y₀ = -7

Therefore:

y - (-7) = -7(x - 3)

y + 7 = -7(x - 3)

The time required to finish a test in normally distributed with a mean of 70 minutes and a standard deviation of 10 minutes. Wha

zalisa [80]

Note that 60 minutes is 1 standard deviation away from the mean and from recalling the 68-95-99.7 rule, the area that will remain is (100 - 68) = 32%. However, we only want the leftmost portion of this area, so the answer is 32%/2 = 16%.

Choose D.
