Answer: B. Accurate but not reliable
Step-by-step explanation:
An experiment is said to be "reliable" when it consistently gives the same answers when done repeatedly, when the experiment is carried out several times it gives the same result each times.
An experiment is said to be " accurate "
when it produce a correct result using the right procedure and method .
In this case the research assessing a new screening tools for early identification of prostate cancer, test result is "accurate but not reliable ", since the consistent test result was not accurate.
Answer:
7.5 years
Step-by-step explanation:
P = $5000,
R = 4.25%,
A = $6593.75,
N =?
SI = A - P = 6593.75 - 5000 =$1593. 75
Answer:
Denny's chowder wont have because the winner was picked anonymously without due fact and figure. The judges would have attached a contestant tag to the chowders prepared for the annual clam festival. The winner was declared without any reason to back up that indeed the chowder had been from Denny's chowder
B..1, Experiments are often blinded this way because of the bias of the individual measuring the experiment
2. Also lack of facts and figures to justify results
Step-by-step explanation:
Do you think that Denny’s chowder would have won the contest if the judging had not been "blind?" Explain.
Although this was not an experiment, your answer to Part (a) helps to explain why those measuring the response in an experiment are often blinded

The winner was declared without any reason to back up that indeed the chowder had been from Denny's chowder.
Using your answer in Part (a), explain why experiments are often blinded in this way
1.. Experiments are often blinded this way because of the bias of the individual measuring the experiment
2. Also lack of facts and figures to justify results
Answer:
If you are <u>traversing squares</u> then 7 different paths can be taken
If you are <u>traversing edges </u> then 36 different paths can be taken
Step-by-step explanation:
I have attached a picture that would describe the grid which is 7 units long.
The solution to the general problem is if you have to take X right steps, and Y down steps then the number of routes is simply the ways of choosing where to take the down (or right) steps. Such that:
Basically its the combination of terms.
In this problem,
If you are <u>traversing squares</u> then there are 6 right steps and 1 down step,
7 C 1 = 7 C 6= 7
If you are <u>traversing edges </u> then there are 7 right steps and 2 down steps:
9 C 2 = 9 C 7= 36
Answer: The value of x must be greater than 3

Explanation:
The triangle inequality theorem will come into play here. The basic idea of this theorem is "take any two sides of a triangle and add them up. That sum must be larger than the third side".
So if we have
a = 12
b = x
c = 15
then the following must hold true (all three inequalities must be true)
a+b > c
a+c > b
b+c > a
Focus on the first inequality and plug in the given values. Then solve for x
a+b > c
12+x > 15
12+x-12 > 15-12
x > 3
So we see that x > 3. Repeat the same for the second inequality
a+c > b
12+15 > x
27 > x
x < 27
Repeat again for the third inequality
b+c > a
x+15 > 12
x+15-15 > 12-15
x > -3
-------------------------
In summary so far, we have
x > 3
x < 27
x > -3
Combine all of those inequalities to form one single compound inequality which is 3 < x < 27
For some reason your teacher doesn't want you to focus on the "less than 27" part, so it seems like s/he only wants the "x > 3" portion.
So this is why x must be larger than 3 (up only til you get to 27 though).
