Answer:
0.7°
Step-by-step explanation:
From the figure:
CF = 4000.2 miles, CE = 4000.01 miles
so FT = √CF² - CT², TE = √CE² - CT²
so FT = 40 miles, TE = 8.94 miles
so ½ × 4000.2 × 4000.01
xsin angle FCE = ½ × 4000 × 140 + 8.94
so sin angle FCE = 0.0122
so angle FCE = 0.7°
so m SB = 0.7°

Answer:
X=11
Step-by-step explanation:
since x=11,11-5=6.
then 6*3=18
Let's first see which box and whisker plots have a range of 17. The range is maximum-minimum. ( the last dot minus the first dot). For A. 20 - 4 = 16, so it can't be A. For B. 36-2 = 34, so it can't be B. For C. 36 - 19 = 17, so it could be C. And for D. 17 - 2 = 15, so it can't be D. C. must be the correct answer, but let's check if the interquartile range is 5. The IQR ( interquartile range) is the 3rd Quartile - the 1st Quartile. 33- 28 = 5. So, C. is the correct answer! Hope this helped!
Let the lengths of pregnancies be X
X follows normal distribution with mean 268 and standard deviation 15 days
z=(X-269)/15
a. P(X>308)
z=(308-269)/15=2.6
thus:
P(X>308)=P(z>2.6)
=1-0.995
=0.005
b] Given that if the length of pregnancy is in lowest is 44%, then the baby is premature. We need to find the length that separates the premature babies from those who are not premature.
P(X<x)=0.44
P(Z<z)=0.44
z=-0.15
thus the value of x will be found as follows:
-0.05=(x-269)/15
-0.05(15)=x-269
-0.75=x-269
x=-0.75+269
x=268.78
The length that separates premature babies from those who are not premature is 268.78 days
Answer:
Each interior angle of a pentagon equals 108 degrees.
Therefore Angle U = 108 degrees.
The angle of the square is 90 degrees.
Therefore, Angle x = 360 - 108 -90 degrees = 162 degrees!
