If you are asking if your work is good,thn yes,you are right
1/2<0.55<5/7
This is the order from least to greatest
If he hits the target 95% of the time, then you could say that he has a probability of 0.95, or 95% of hitting the target. Let p = the probability of hitting the target or p = 0.95. So you are interested that he misses the target at least once - this could be thought of as not getting a perfect score. So to get a perfect score, it is 0.95 for each target -- 0.95^15 for 15 targets is 0.464. Thus to miss at least one target he needs to NOT have a perfect score -- 1 - 0.464 = 0.536, or 53.6% of happening. Enjoy
Answer:
D. 20°
Step-by-step explanation:
The entire angle = 90 degrees you can tell that from the corner indicator
Set the two expressions equal to 90
(3x+10) + (x) = 90
Combine like terms
4x + 10 = 90
Subtract 10 from both sides to cancel it out
4x = 80
Divide each side by 4
x = 20
Check it by substituting x for 20
3(20) + 10 = 70 x = 20 70 + 20 = 90
