You're looking for a value

such that

Because the distribution is symmetric, the value of

in either case will be the same.
Now, because the distribution is continuous, you have that

The mean for the standard normal distribution is

, and because the distribution is symmetric about its mean, it follows that

.

You can consult a

score table to find the corresponding score for this probability. It turns out to be

.
The same as angle as measurement of angle 1. Corresponding angles.
Answer:
x to the third power is x cubed or x^3.
the sequence is in multiples of 4 (2*4=8, 8*4=32, 32*4=128)
so 128*4=512, 512*4=2048, 2048*4=8192 & 8192*4=32768
2+8+32+128+512+2048+8192+32768=43690
Answer for question 1: B. Because 10 times 1 is 10 kg and is not close to 100
Answer for question 2: B. because it is within the scientific measurement of between 1-10
Answer for question 3: C. Because 24-2 is 22
