Answer:
(1/3)(9x+27) > x + 33
multiply out the 1/3
3x + 9 > x + 33
subtract x and 9 from both sides
2x > 24
x > 12
D) because you dont include the 12
Step-by-step explanation:
Answer:
Step-by-step explanation:
Data given and notation
n=1500 represent the random sample taken
estimated proportion of of chips fail in the first 100 hours
is the value that we want to test
represent the significance level
z would represent the statistic (variable of interest)
represent the p value (variable of interest)
Concepts and formulas to use
We need to conduct a hypothesis in order to test the claim that the actual percentage that fail is different from the stated percentage. Find the value of the test statistic.:
Null hypothesis:
Alternative hypothesis:
When we conduct a proportion test we need to use the z statisitc, and the is given by:
(1)
The One-Sample Proportion Test is used to assess whether a population proportion
is significantly different from a hypothesized value
.
Calculate the statistic
Since we have all the info requires we can replace in formula (1) like this:
Answer:
y=6/7x+11/7
Step-by-step explanation:
m=(y2-y1)/(x2-x1)
m=(-1-5)/(-3-4)
m=-6/-7
m=6/7
y-y1=m(x-x1)
y-5=6/7(x-4)
y=6/7x-24/7+5
y=6/7x-24/7+35/7
y=6/7x+11/7
Vertical stretch occurs when a function value is multiplied by a number greater than 1.
For a function f(x), m*f(x) stretches f(x) in y direction if m is greater than 1.
From the given options we can see only A option lists such a case where an exponential function is being multiplied by a number greater than 1.
So, the answer to this question is A
Equation
Because expressions don't contain equal signs
