55 is not a perfect square, and is factored into 11 and 5, neither of which are perfect squares, so the square root of 55 is simply sqrt(55).

The square root of 55 is 7.416 it has decimals because it is not a perfect square root

The sides of this rectangle are

Naddik [55]

The longer side is at first 7cm and the shorter is 2cm.

So since 7cm(the longer side)×5=35cm then the shorter side(2cm) multiplied by 5 should give you the right answer.

You are testing 0:=100 against :<100 based on an SRS of 24 observations from a normal population. The data gives ¯=9 and =2.4

bekas [8.4K]

Answer:

-185.75297

Step-by-step explanation:

Solution:-

- We are testing whether the population mean u is equal to 100 as per claim.

Null hypothesis: u = 100

- Where a alternate hypothesis suggest that the population mean ( u ) may be lower:

Alternate hypothesis: u < 100

- We are given sample data parameters which are assumed to be normally distributed:

sample mean, x_bar = 9

sample standard deviation, s = 2.4

- A sample of n = 24 observation was taken from a population of ( N ) with unknown population standard deviation ( σ ).

- The conditions of standard normal distribution are no longer applicable i.e:

n = 24 < 30

unknown population standard deviation ( σ )

- We will model the sample using t-distribution with ( n - 1 ) = 23 degrees of freedom.

- The t-statistics of the sample mean x_bar can be determined from standard t-distribution:

$t-test = \sqrt{n}* \frac{x_b_a_r - u}{s} \\\\t-test = \sqrt{24}* \frac{9 - 100}{2.4} \\\\t-test = -185.75297$

- The t-test value for mean ( u ) is -185.75297

4(4m-3)-m(m-5)=-52 need all the steps

nadezda [96]

$\huge\mathcal {♨Answer♥}$

$\large\texttt{Simplifying: }$

4(4m -3) + -1m(m + -5) = -52

$\large\texttt{Reorder the terms: }$

4(-3 + 4m) + -1(m + -5) = -52

(-3 * 4 + 4m * 4) + -1(m + -5) = -52

(-12 + 16m) + -1(m + -5) = -52

$\large\texttt{Reorder the terms: }$

-12 + 16m + -1(-5 + m) = -52

-12 + 16m + (-5 * -1 + m * -1) = -52

-12 + 16m + (5 + -1m) = -52

$\large\texttt{Reorder the terms: }$

-12 + 5 + 16m + -1m = -52

$\large\texttt{Combine like terms: }$

-12 + 5 = -7

-7 + 16m + -1m = -52

$\large\texttt{Combine like terms: }$

16m + -1m = 15m

-7 + 15m = -52

$\large\texttt{Solving: }$

-7 + 15m = -52

-7 + 7 + 15m = -52 + 7

$\large\texttt{Combine like terms: }$

-7 + 7 = 0

0 + 15m = -52 + 7

15m = -52 + 7

$\large\texttt{Combine like terms: }$

-52 + 7 = -45

15m = -45

$\large\texttt{Divide each side by '15'. }$

15m ÷ 15 = -45 ÷ 15

m = -3

$\large\texttt{Simplifying: }$

m = -3
