Answer:
7y+21
Step-by-step explanation: i solve it hope this help.
Answer:
The expression x2y - 2xy - 24y can be factored by first factoring out a common factor of y.
<h2>
y(x-6)(x+4)<===Your Answer!!!!!!!!!!!!!!!!!!!!!!!</h2>
60(pi/180)=pi/3
.5(12^2)(pi/3)
72(pi/3)
24pi
The number of students with heights less than 163 cm should be expected is 12.
According to the statement
The mean of height is 175 cm
and the standard deviation of height is 6 cm.
We use normal distribution here with formula
Z= X - μ /σ
Here X is 167.5 and μ is 175 and σ is 6 cm.
Substitute the values in it then
Z = 167.5 - 175 / 6
Z = -1.25
-1.25 have a p value 0.012
Out of 1000 students:
0.012 x 1000 = 12.
So, The number of students with heights less than 163 cm should be expected is 12.
