<span> (a) if 1 woman is randomly selected, find the probability that her height is less than 64 in
using z-score formula:
z-score=(x-mu)/sig
(64-63.5)/2.8
=0.18
thus
P(x<64)=P(z<0.18)-=0.5714
B] </span><span> if 33 women are randomly selected, find the probability that they have a mean height less than 64 in
using the central limit theorem of sample means, we shall have:
2.8/</span>√33=0.49
since n>30 we use z-distribtuion
z(64)=(64-63.5)/0.49=1.191
The
P(x_bar<64)=P(x<1.191)=0.8830
Truck speed be x
car travel at x+19
they travel in opposite directions
so the separation is (x+x+19) * no. of hours
1048 = (2x+19)*8
x = ((1048/8) - 19)/2
=56
truck speed is 56 miles per hour
car speed is 56+19 = 75 miles per hour
Answer:
3.47 and 3.21
Step-by-step explanation:
Let us assume the nails length be X
Value let separated the top 3% is T and for bottom it would be B
Now converting, we get
Based on the normal standard tables, we get
Now compare these two above equations
So for top 3% it is 3.47
Now for bottom we applied the same method as shown above
Based on the normal standard tables, we get
Now compare these two above equations
hence, for bottom it would be 3.21
Answer:
Well I recently tore my meniscus a little bit, but you said yours popped/locked, I don't think mine did that. But it could be a bigger meniscus tear then mine, don't take my word for it tho, I'm no orthopedic or doctor. And for the second time in 7-9 months?? I'd definitely go get that checked out if you can.
Step-by-step explanation:
Answer:
f(x)=-|x|
Step-by-step explanation:
We have been given a graph of f(x) which resembles with the graph of function g(x) where g(x)=|x|.
It says that graph is flipped over the x-axis.
Now we have to find about which of the following choice correctly describes the given graph.
We know that |x| means absolute value of x so that means g(x)=|x| is absolute function in shape of V.
We know that flipping over x-axis can be done by changing f(x) into -f(x).
<u>Hence correct answer is choice D) F(x)=-|x|</u>
