Answer:
I'm sorry pls retake the pic really quickly.. I can't see the entire problem!
Then I'll add my answer if I can! Thx!
A. Because it is less than 1 times 111.
For 39% of all observations that are greater than z on the normal distribution table, the percentage of observations that are lesser than z is
100 - 39 = 61%
The proportion is 61/100 = 0.61
From the normal distribution table, the value of z corresponding to this proportion is 0.28
Thus, the required value of z is 0.28
Given:
M is the midpoint of AB.
M(2,0) and A(-3, 3).
To find:
The coordinates of point B.
Solution:
Midpoint formula:
Let the coordinates of point B are (a,b). Then, using the midpoint formula, we get
On comparing both sides, we get
And,
Therefore, the coordinates of point B are (7,-3).
2 radians = 2 full rotations
pi = 3.14
circumference of wheel = 2(pi)r
= 20 * 3.14
=62.8 cm
= 0.628m
meters rolled = 0.628 * 2
=1.256 m
