Answer:
1
Step-by-step explanation:
the denominators must be the same so, since 4 goes evenly into 24 we can create an equivalent fraction from 3/4 to 18/24 (multiply numerator and denominator by 6)
now you can add:
+
=
=
since the numerator is larger than the denominator this is called an improper fraction and can be changed into a mixed number by dividing 24 into 33
24 goes into 33 one time with a remainder of 9
so 33/24 = 1 wherein 9 and 24 can each have a 3 factored out to make it fully simplified
9÷3 = 3
24÷3 = 8
final answer is 1
Answer:
P(x < 92) is 0.16
Step-by-step explanation:
We are given that the normal distribution has a mean of 98 and a standard deviation of 6.
Mean =
Standard deviation =
We are supposed to find P(x < 92)
Formula :
Z=-1
Refer the z table for p value
So,p value = 0.1587
So, P(x < 92) is 0.16
Option A is true
Hence P(x < 92) is 0.16
