Answer:
∠7 = 81°
Step-by-step explanation:
∠1 = ∠7
3x + 18 = 2x + 39
3x - 2x = 39 - 18
x = 21
∠7 = 2x + 39
∠7 = 2(21) + 39
∠7 = 42 + 39
∠7 = 81°
Answer:1/4×l +(2 1/2) = 4
l = 6
Step-by-step explanation:For l laps around a 1/4 mile track, the total distance is ...
l×(1/4)
After adding 2 1/2 miles to that, Gabriella's total distance was 4 miles:
l×(1/4) +(2 1/2) = 4 . . . . an equation to find l
__
We can solve this equation by subtracting 2 1/2, then multiplying by 4.
l×(1/4) = 1 1/2
l = 4(1 1/2)
l = 6 hope it helps
Assuming a standard normal distribution, the positive value of interest will be that corresponding to the 50 + 36/2 = 68th percentile. A suitable probability calculator will give that value as 0.46770.
The values that are within ±0.46770 standard deviations from the mean will have a probability of 0.36.
