Answer: 0.33 , 1/4 , 1/8 , 0
Step-by-step explanation:
1/4 is 0.25
1/8 is 0.125
After converting to decimal it’s all easy
Answer:
The number is
students
Step-by-step explanation:
From the question we are told that
The population mean is
The standard deviation is 
The sample size is n = 2000
percentage of the would you expect to have a score between 250 and 305 is mathematically represented as

Generally

So


From the z table the value of 
and 


The percentage is 
The number of students that will get this score is


A. First move all to the left side of the equation(Normal form)
x^3 - 49x= 0
B. Factor out an x, which is the GCF (Factored form)
x(x^2 - 49) = 0
C. Find solutions by making each x piece equal to 0. The first part is just x=0 and the second part is just factoring the difference of squares and then solving.
x=0, x^2 - 49 =0
x=0, x + 7 = 0, x - 7 = 0
Therefore, the answers for Part C are:
x = 0, x = -7, x = 7
