Step-by-step explanation: this is how you would estimate the square root of a number if it is not a perfect square, here are 3 steps to help.

1. pick an estimate of the square root. example, if we find sqrt of 5, if we pick 2.

2. divide the number by the estimate. example, 5/2 = 2.5

3 . average the result and the estimate

and this is how you would estimate the square root of a number that is not a perfect square, i hope this is useful. or this

approximate between two whole numbers by finding the perfect squares nearest to the target number. indentify which value the non perfect square root is closet to, then use the irative process.

both of the explanations i have stated are correct so either one of them will work.

Answer:When you use a radical then if it gives a decimal then you just round it however it said like to the nearest whole or however it says to do it

11. A square-shaped floor is covered with congruent square tiles. If the total number of tiles that lie on the two diagonals is

natita [175]

361 congruent square tiles would be needed to cover the square shaped floor.

<h3>Equation</h3>

An equation is an expression that shows the relationship between two or more variables and numbers.

Since the number of tiles lying on both diagonals is 37. Let x represent the number of tiles on each side.

Counting one tile twice, there are:

37=2x-1
x=19 tiles on each side.

19² = 361

361 congruent square tiles would be needed to cover the square shaped floor.

An electric sale gives a reading equal to the true weight plus a random error that isnormally distributed with mean 0 and standa

Pepsi [2]

Answer:

a) 95% confidence interval estimate of the true weight is (3.026, 3.274)

b) 99% confidence interval estimate of the true weight is (2.944, 3.356)

Step-by-step explanation:

Confidence Interval can be calculated using M±ME where

M is the mean of five successive weightings (3.150)

ME is the margin of error from the mean

And margin of error (ME) can be calculated using the formula

ME= $\frac{t*s}{\sqrt{N} }$ where

t is the corresponding statistic in the given confidence level and degrees of freedom(t-score)

s is the standard deviation of the random error (0.1)

N is the sample size (5)

Using the numbers 95% confidence interval estimate of the true weight is:

3.150± $\frac{2.776*0.1}{\sqrt{5} }$ ≈3.150±0.124

And 99% confidence interval estimate of the true weight is:

3.150± $\frac{4.604*0.1}{\sqrt{5} }$ ≈3.150±0.206

miv72 [106K]

Answer:

The answer would be 27π

Step-by-step explanation:

the area is 36pi and the shaded region is 3/4 of the circle, as a 90 degree angle is 1/4 of a 360 degree circle. 3/4 of 36pi is 27pi
