Answer:

Answer = 12 x^{-5}

Step-by-step explanation:

Step 1:-

simplifying 3 x^{-2} × 4 x^{-3}

3 × 4(x^{-2} )(x^{-3} )

base are equal powers are added

on simplification 12 x^{-5}

A hat contains four balls. The balls are numbered 2, 4, 4, and 7. One ball is randomly selected and
ASHA 777 [7]

Answer:

If the sum is 6, a small cone will be ordered

If the sum is 8 or 9, a medium cone will be ordered.

If the sum is 11, a large cone will be ordered.

Step-by-step explanation:

If the sum is 6, a small cone will be ordered

If the sum is 8 or 9, a medium cone will be ordered.

If the sum is 11, a large cone will be ordered.

The description above accurately explains how a fair decision can be made in this situation. Because the least sum of value = 6

While the highest sum of value of number = 11.

What is the critical f-value when the sample size for the numerator is four and the sample size for the denominator is seven? us
fgiga [73]

Assuming that we are performing a two-tailed test, the significance level is α = 0.1 would be dispersed in the distribution's tails with α/2  = 0.05.

And we must consider two critical values that add up to 0.05 of a area on every tail of a F distribution with a 10 degree angle.

\begin{aligned}&F_{\alpha / 2}=0.311 \\&F_{1-\alpha / 2}=4.06\end{aligned}

<h3>What is critical f-value?</h3>

An F statistic is one that is ascertained through an ANOVA test. It helps determine the relevance of the variable groups.

Now, according to the question;

We understand that sample size for numerator is 11 and also the sample size for denominator is 7. So, for each case, we can calculate a degrees of freedom as follows:

\begin{aligned}&d f_{\text {num }}=11-1=10 \\&d f_{d e n}=7-1=6\end{aligned}

In this case, the F distribution could have 10 degrees of freedom with in numerator as well as 6 degrees of freedom in the denominator.

Assuming we are conducting a two-tailed test, the significance level of α = 0.1 will be distributed in the tails of the distribution with α/2  = 0.05.

Now, locate two critical values that collect 0.05 of a area on every tail of F distribution to 10 degrees of freedom again for numerator and 6 degrees of freedom for the denominator and we obtained using a table or excel;

\begin{aligned}&F_{\alpha / 2}=0.311 \\&F_{1-\alpha / 2}=4.06\end{aligned}

Therefore, the critical f-value for the two-tailed experiment is found.
