Answer:
C
Step-by-step explanation:
| x | > 10
Has solutions that go infinitely high to the right and infinitely low to the left on the number line.
That is x > 10 or x < - 10
This is indicated on Graph C
The answer is c.261 you add 13 and16 together then multiply that number by9
C
She'd have to have given her more than 48 dollars to receive more than 30 dollars back
It can't be D because that implies she could've received exactly 30 dollars in change and the question states she received more than that.
Answer:
a
The 95% confidence interval is
b
The sample proportion is
c
The critical value is
d
The standard error is
Step-by-step explanation:
From the question we are told that
The sample size is n = 200
The number of defective is k = 18
The null hypothesis is
The alternative hypothesis is
Generally the sample proportion is mathematically evaluated as
Given that the confidence level is 95% then the level of significance is mathematically evaluated as
Next we obtain the critical value of from the normal distribution table, the value is
Generally the standard of error is mathematically represented as
substituting values
The margin of error is
=>
=>
The 95% confidence interval is mathematically represented as
=>
=>
Answer:
469
Step-by-step explanation:
What you need to do is divide 335 by 5 to see how many miles are in one hour. You'll get 67. Then you can multiply 67 by 7 to get an answer of 469.
