Answer:
(85.62, 90.38).
Step-by-step explanation:
The missing data can be assumed to be we have the following information:
¯x =88, s=10, n=70
Substituting the values in the following formula, we compute the 95% C.I for true population mean diastolic pressure as shown below:
95% C.I.=¯x±t(0.95,n−1)⋅Sm=¯x±t(0.95,70−1)⋅s√n=88±1.99⋅10√70=(85.62,90.38)
The answer is (85.62, 90.38).
Answer:
Or, by approximating:
Step-by-step explanation:
Let’s convert this to standard form. We have:
Subtract 5x² from both sides:
And add 6x and 1 to both sides:
This is not factorable. So, we will need to use the quadratic formula.
The quadratic formula for a quadratic in standard form is given by:
In this case, a=3; b=6, and c=1.
Substitute appropriately:
Simplify:
We can simplify the square root:
Hence:
Simplify:
Hence, we will have two solutions:
Approximating them, we can see that our solutions are approximately:
1/4
each side length of the orange shape is one quarter of the length or the black shape so it is one quarter of the size
