We know angle x=y(vertically opposite angles)
Since 3 angles lie on a straight line,
y+60+70=180 (linear pair)
y+130=180
y=180-130
y=50 degrees
Answer:
About 30
Step-by-step explanation:
1ST: see how many odd numbers are in 1-6 (which is 3)
2nd: Divide 64 by 3 (when rounded it equals around 30)
Answer:
382 ft³ (3 s.f.)
Step-by-step explanation:
Radius= diameter ÷2
Rdaius of sphere
= 9 ÷2
= 4.5 ft
Volume of sphere
= 382 ft³ (3 s.f.)
21499 +12*x=22.75*x
21499=22.75x-12x
21499=10.75x
x=21499/10.75≈1999.9≈2000 books
Answer: 0.0386
Step-by-step explanation:
Given: The population of 400 tall women has a mean height of 179.832 cm and a standard deviation of 12.192 cm.
Let X be a random variable that represents the height of woman.
Sample size : n= 50
The probability that the mean for this sample group is above 182.88 will be :
Hence, Required probability = 0.0386
