Suppose your boss wants you to obtain a sample to estimate a population mean. Based on previous analyses, you estimate that 49 i

VashaNatasha [74]

Answer:

the minimum sample size n = 11.03

Step-by-step explanation:

Given that:

approximate value of the population standard deviation $\sigma$ = 49

level of significance ∝ = 0.01

population mean = 38

the minimum sample size n = ?

The minimum sample size required can be determined by calculating the margin of error which can be re[resented by the equation ;

Margin of error = $Z_{ \alpha /2}} \times \dfrac{\sigma}{\sqrt{n}}$

$38 = \dfrac{2.576 \times 49}{\sqrt{n}}$

$\sqrt{n} = \dfrac{2.576 \times 49}{38}$

$\sqrt{n} = \dfrac{126.224}{38}$

$\sqrt{n} = 3.321684211$

$n= (3.321684211)^2$

n ≅ 11.03

Thus; the minimum sample size n = 11.03

Is y= -9/5x + 1/5 perpendicular to y= 5/9x + 2/9

Lunna [17]

The given lines are perpendicular

Step-by-step explanation:

if Two lines are perpendicular then their slopes are

m $m_{1}=-\frac{1}{m_{2}}$

Where m₁ is slope of first line and m₂ is the slope of second line.

Since the lines are in slope-point form the standard form is:

$y=mx+b$

where m is the slope

The slope of first line y= -9/5x + 1/5 is: m₁ = -9/5

The slope of second line y= 5/9x + 2/9 is: m₂= 5/9

So, m $m_{1}=-\frac{1}{m_{2}}$ i.e $-\frac{9}{5}=\frac{5}{9}$

So, The given lines are perpendicular

Rewrite y=5(14)t/6 in the form y=a(1+r)t or y=a(1−r)t. Round the value of r to the nearest ten thousandth. Then tell whether the

Sveta_85 [38]

Answer:

$y=5(1+0.5525)^t$ where r=0.5525 which is in the form of $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

The expression represents an exponential growth function.

Step-by-step explanation:

Given that $y=5(14)^{\frac{t}{6}$

To rewrite the given equation in the form $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

$y=5(14)^{\frac{t}{6}$

$=5((14)^{\frac{1}{6}})^t$

$=5[1.5525]^t$

$y=5(1+0.5525)^t$ where r=0.5525 which is in the form of $y=a(1+r)^t$ or $y=a(1-r)^t$ ..

Since 1.5525 > 1, we have that the expression represents an exponential growth function.
