Answer:
x = 9
Step-by-step explanation:
Answer:
we know that mean of the data set is
Sum of all terms / total no. of terms
mean = 120+145+130+80+95+100+340+n / 8
140 = 1010+n / 8
140*8 = 1010 + n
1120 = 1010 + n
1120 - 1010 = n
110 = n
therefore the value of n should be 110

Answer:
D) 4.7
Step-by-step explanation:
this perpendicular connection with the circle center cuts this intersecting line in half, which is therefore on both sides of x 6.5 long.
I assume 16 is the diameter, so the radius is 8.
therefore, x is one side of the right-angled triangle of
radius
x
half of the intersecting line
Pythagoras
8² = x² + (6.5)²
64 = x² + 42.25
21.75 = x²
x = 4.7
