It would be: 6 ( 6- 4)
= 6 ( 2)
= 12
So, Your Answer would be 12
Hope this helps!
I think... 1500
Step-by-step explanation:
multiply 30 and 25 then times 750 as your answer by 2 to get 1500
Answer:
-9/7
Step-by-step explanation:
Put the equation into y = mx + b form, by first isolating y:
9x + 7y= 7
7y = -9x + 7
Divide each side by 7:
y = -9/7x + 1
So, -9/7 is the slope.
Answer:
The 80% confidence interval for the population proportion of oil tankers that have spills each month is (0.199, 0.257).
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the zscore that has a pvalue of 
.
Suppose a sample of 333 tankers is drawn. Of these ships, 257 did not have spills.
333 - 257 = 76 have spills.
This means that 
80% confidence level
So 
, z is the value of Z that has a pvalue of 
, so 
.
The lower limit of this interval is:
The upper limit of this interval is:
The 80% confidence interval for the population proportion of oil tankers that have spills each month is (0.199, 0.257).
Answer:
So the question is asking you to write an expression which can be defined as a mathematical equation that contains two numbers (usually a <u>variable</u> represented by a letter from the english alphabet and a <u>constant</u> like 1, 2, 15, 73, or 10) and at the very least, one operation. So we are instructed to write an expression WITH an exponent. Examples of exponents would be squaring or cubing a number: 2² or 5³
With this kind of problem its more of a guess and check to try and see which numbers would make the equation true/equal to 24.
Here is an example of what I would put down:
24 = 3x³
24/3 = x³
8 = x³
2 x 2 x 2 = x³
2 = x
Check by plugging our x-value in:
24 = 3 x 2³
24 = 3(8)
24 = 24
