Answer:

75°

Step-by-step explanation:

Since the 2 angles are supplementary and TC is a perpendicular bisector, we know that m∠ATC is 90°

All we need to do is simply subtract 15° from 90° to find m∠ATB:

90 - 15 = 75°

Answer:

Solution,

Let m<ATB be X

$x + 15 + 90 = 180$

(sum of angle in straight line)

$x + 105 = 180$

subtract 105 on both sides

$x + 105 - 105 = 180 - 105 \\ x = 180 - 105 \\ x = 75$

Hope this helps ...

Good luck on your assignment..

Answer:

See below

Step-by-step explanation:

B) The correlation coefficient is $r=0.75$ , which can be determined by plugging the data into a TI-84 calculator.

C) A correlation coefficient of $r=0.75$ indicates that the correlation between the independent and dependent variable (x and y in this case) is moderately strong with a positive correlation. The closer $r$ is to 1, the stronger the positive correlation. The closer $r$ is to -1, the stronger the negative correlation. If $r$ is closer to 0, then there's no correlation.
