Answer:
That is right
Step-by-step explanation:
Answer:
The answer is approximately 24.041 inches (round to the nearest tenth, hundredth, or thousandth if it is indicated in the instructions.)
Step-by-step explanation:
First, I figured out what the square root of 289 is. The square root of 289 is 17.
Given that this is a square we are dealing with, we can assume that all sides are equal.
So, when you draw a diagonal down the square, it becomes two triangles, one of which we can use the Pythagorean theorem for.
a^2 + b^2 = c^2. Thus, 17^2 + 17^2 = 578. The square root of 578 unfortunately does not come out evenly, so we are left with approximately 24.041 inches.
I hope this helps!
Answer:
10
Step-by-step explanation:
Pythagorus thereom. So
8sq +6sq= xsq
64+36=100
Sq root 100 is 10
They both bought 5 1/3 kg of apples because 1 1/2 + 3 5/6= 5 1/3 kg
Answer:
95% Confidence interval for y
= (-9.804, -5.979)
Lower limit = -9.804
Upper limit = -5.979
Step-by-step explanation:
^y= 2.097x - 0.552
x = -3.5
Standard error = 0.976
Mathematically,
Confidence Interval = (Mean) ± (Margin of error)
Mean = 2.097x - 0.552 = (2.097×-3.5) - 0.552 = - 7.8915
(note that x=-3.5)
Margin of Error is the width of the confidence interval about the mean.
It is given mathematically as,
Margin of Error = (Critical value) × (standard Error of the mean)
Critical value for 95% confidence interval = 1.960
Standard Error of the mean = 0.976
95% Confidence Interval = (Mean) ± [(Critical value) × (standard Error of the mean)]
CI = -7.8915 ± (1.960 × 0.976)
CI = -7.8915 ± 1.91296
95% CI = (-9.80446, -5.97854)
95% Confidence interval for y
= (-9.804, -5.979)
Hope this Helps!!!
