Answer:
a. Fred's margin of error is larger than Ted's.
Step-by-step explanation:
Margin of error of a confidence interval:
In which z is related to the confidence level(the higher the confidence level the larger the value of z) 
is the standard deviation of the population and n is the size of the sample.
From this, we have that:
A higher confidence level leads to a larger margin of error.
A larger sample size leads to a smaller margin of error.
In this question:
Same confidence level.
Fred's sample is smaller, so his margin of error will be larger.
The correct answer is given by option a.
Answer:
The Answer is c: 4x5 + x3 + 2x2 – 3
Step-by-step explanation:
For a sec, I thought this was AB Calculus with derivatives and second derivatives but it isn't! That's a good thing!
Anyhow, all the problem is asking is to plug in the values of time to find the height.
We see when time is zero, the height is 64 feet. Plug in zero for the "t" variable and you'll get 64 feet.
When the penny has dropped for half a second or 0.5 seconds, we know the "t" variable and plug in that value.
h = -16(.5)^2 + 64.
h = -16(.25) + 64.
h = -4 + 64.
h = 64 feet when the penny has dropped for half a second.
I encouraged student progression when given the knowledge to complete a problem. We know how to complete the rest of the table. Good luck!
Answer:
Step-by-step explanation:
he spent 75% of his savings to buy a camera that costs 325....
so 75% of his original savings is 325
let x represent his original savings...." of " means multiply.." is " means equals
75%(x) = 325....turn ur percent into a decimal
0.75x = 325.....divide both sides by 0.75
x = 325 / 0.75
x = 433.33 <=== ur answer
check...
0.75(433.33) = 325
324.99 (rounds to 325) = 325
