Here is how to find the area using the given lengths in regards to x

25x^2 + 25x^2 = c^2

50x^2 = c^2

c = \sqrt{50x^2}

\sqrt{50x^2} x \sqrt{50x^2}

x\sqrt{50} x x\sqrt{50}

2x\sqrt{50}

x^{2}\sqrt{50}

Basile [38]

Answer:

[143.61, 156.39]

Step-by-step explanation:

Because the population standard deviation is not available AND the sample size is less than 31, we can use a t procedure here.

Plug these values into your calculator:

Sample mean = 150

Sample size = 16

Standard deviation = 12

Confidence level = 95% = 0.95

and get [143.61, 156.39] as your confidence interval

if a fish tank,8/11 of the fish have a red stripe on them.If 16 of the fish have red stripes,how many total fish are in there
Arisa [49]
8/11--------> 16

to find the total number of fish, divide 16 by 8 and multiply it by 11,

16÷8=2
2×11=22

total number of fish= 22

check,

22÷11×8=16

if you want to find the number of fish without the red stripes,

8/11--------> 16
11/11------->22
3/11--------->?

you can either subtract 16 by 22=6
or
22÷11×3=6

hope this helps......
