We have been given that in ΔBCD, the measure of ∠D=90°, the measure of ∠C=42°, and CD = 7.5 feet. We are asked to find the length of DB to nearest tenth of foot.
First of all, we will draw a right triangle using our given information.
We can see from the attachment that DB is opposite side to angle C and CD is adjacent side to angle.
We know that tangent relates opposite side of right triangle to adjacent side of right triangle.
Therefore, the length of DB is approximately 6.8 feet.

Step-by-step explanation: JUST DID THE TEST
You have to calculate the probability for the given average:
= 3/200 = 0.015 = 1.5%
For 50,000 phones you have to multiply the probability by 50,000:
0.015*50,000 = 750 phone defectives if the company produced 50,000
B) 0.45 and D) 9/20 are both eqivalent to 45%.
The range is the difference between her highest grade and her lowest grade.
Highest grade = 95
Lowest grade = 78
Range = 95 - 78 = 17
