Answer is D. As price of 32 oz bottle is $1.92 so to find the price of 1 oz, we will divide $1.92 by 32. 1.92/32 = 0.06 So our answer will be 0.06$ per oz

Answer:

cost per ounce is 0.06 per ounce

Step-by-step explanation:

A 32 oz bottle of water costs $1.92.

we need to find the cost of one ounce.

To find the cost of 1 ounce , we need to divide the total cost by 32 oz

cost of 1 oz= $\frac{1.92}{32} =0.06$

0.06 is the unit price

So, the cost per ounce is 0.06 per ounce

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test

SSSSS [86.1K]

A manager wants to test whether two normally distributed and independent populations have equal variances. the appropriate test statistic for this test is a "F-statistics."

<h3>What is F-statistics?</h3>

An F statistic is a value obtained after performing an ANOVA test or even a regression analysis to determine whether the means of two populations differ significantly.

Some key features regarding the F-statistics are-

It is comparable to a T statistic from the a T-Test; a T-test would then inform you when a single result is statistically significant, whereas a F test would then tell you if a set of variables is statistically significant.
When determining whether your total results are significant, you must use the F statistic in conjunction with the p value. Why?
A significant result does not imply that all of your variables have been significant.
The statistic is simply comparing the cumulative influence of all the variables.

The acceleration of the particle is given by the formula mentioned below:

$a=\frac{d^2s}{dt^2}$

Differentiate the position vector with respect to t.

$\begin{gathered} \frac{ds(t)}{dt}=\frac{d}{dt}\sqrt[]{\mleft(t^3+1\mright)} \\ =-\frac{1}{2}(t^3+1)^{-\frac{1}{2}}\times3t^2 \\ =\frac{3}{2}\frac{t^2}{\sqrt{(t^3+1)}} \end{gathered}$

Differentiate both sides of the obtained equation with respect to t.

$\begin{gathered} \frac{d^2s(t)}{dx^2}=\frac{3}{2}(\frac{2t}{\sqrt[]{(t^3+1)}}+t^2(-\frac{3}{2})\times\frac{1}{(t^3+1)^{\frac{3}{2}}}) \\ =\frac{3t}{\sqrt[]{(t^3+1)}}-\frac{9}{4}\frac{t^2}{(t^3+1)^{\frac{3}{2}}} \end{gathered}$

Substitute t=2 in the above equation to obtain the acceleration of the particle at 2 seconds.

$\begin{gathered} a(t=1)=\frac{3}{\sqrt[]{2}}-\frac{9}{4\times2^{\frac{3}{2}}} \\ =1.32ft/sec^2 \end{gathered}$

The initial position is obtained at t=0. Substitute t=0 in the given position function.

$\begin{gathered} s(0)=-23\times0+65 \\ =65 \end{gathered}$

Naomi has 45 minutes to get ready for school she spends x minutes getting dressed write an expression that respetents the number

andriy [413]

ANSWER

$(45 - x) \: minutes$

EXPLANATION

Total minutes Naomi has at her disposal is 45 minutes.

The number of minutes she spends getting dressed is

$x$

To find the number of minutes she still has to get ready, we subtract the minutes spent from the total minutes.

The number of minutes she still have to get ready is

$(45 - x) \: minutes$
