14.5 (15 rounded).
To find the answer, we are going to have to multiply the amount of phones bought by the decimal equal to the percent chance that it will be defective. The decimal would be 0.029 because that is 2.9% of 1, and in this case 1 is equal to 100%. Now we multiply: 500*0.029 = 14.5. Obviously there can't be half a phone defective, so if the teacher tells you to round, round up to 15. If they don't tell you, then leave it as 14.5.
Lyn's speed is 3 miles per hour.
That is distance travelled in 60 minutes
= 3 miles
So, distance travelled in 25 minutes
= 3 * 25 / 60 miles
= 25/ 20 miles
= 1.25 miles
New speed of Lyn is 5 miles per hour
That is, for travelling 5 miles, time required = 60 minutes
So, for travelling 1.25 miles, time required = 60 * 1.25 / 5 minutes
= 60/ 4 minutes
= 15 minutes.
It will take her 15 minutes, if she runs at a speed of 5 mph.

Answer:
∠1 = 48°
∠2 = 132°
∠3 = 48°
Step-by-step explanation:
∠1 = (360-132-132)/2 = 48°
∠2 = 132° because it is the alternate angle to 132°
∠3 = 48° because it is the alternate angle to ∠1
