3. x+100 = 90 alternate interior angles are equal

subtract 100 from each side

x+100 - 100 = 90-100

x = -10

4. 17x+1 = 120 alternate exterior angles are equal

subtract 1 from each side

17x+ 1 -1 = 120 -1

17x = 119

divide each side by 17

17x/17 = 119

x =7

It would be ASA(angle side angle)

if 2 angles and an included side are congruent, then the two triangles are congruent.

Answer:

$P(X\geq 3.4)=0.0228$

Step-by-step explanation:

Given the mean is 3.2, standard deviation is 0.8 and the sample size is 64.

-We calculate the probability of a mean of 3.4 as follows:

#First determine the z-value:

$z=\frac{\bar X -\mu}{\sigma/\sqrt{n}}\\\\=\frac{3.4-3.2}{0.8/\sqrt{64}}\\\\=2.000$

#We then determine the corresponding probability on the z tables:

$Z(X\geq 3.4)=1-P(X$

Hence, the probability of obtaining a sample mean this large or larger is 0.0228

Suppose a line has slope 4 and passes through the point (-2,5). Which other point must also be on the graph?

xxMikexx [17]

Slope of 4 means you add 4 to the y and 1 to the x so the answer is (-1,9)
