Is the right answer is 110

Mathematics
1 answer:
taurus [48]3 years ago
8 0

Answer: 140

Step-by-step explanation:

Angles 3 and 4 have equivalent degree values. Set them equal to each other: x + 30 = 2x - 80

Solve for x: add 80 to both sides

x + 110 = 2x

Then subtract x from both sides

110 = x. This is x, not the final answer. The question asks for the measure of angle 3.

To get the measure of angle 3, plug in 110 for x.

Instead of x + 30, calculate 110 + 30.

So, angle 3 is 140 degrees.

Tutor O-Rama claims that their services will raise student SAT math scores at least 50 points. The average score on the math por
Novosadov [1.4K]

Answer:

See below

Step-by-step explanation:

The score increase was 35 points. They claimed an increase of at least 50 points.  For a significance level of 5%, the z-score for the situation needs to be at smaller than -1.645.  For a significance level of 1%, the z-score needs to be smaller than -2.325

The z score for our situation:  z = (385 - 350)/50 = 0.7

The average score of 385 of Tutor O-Rama scores is not significantly different from the average of the other students SAT scores.  The evidence doesn't support their claim of being effective tutoring.
