Answer:

243cm^3

Step-by-step explanation:

By Pythagoras' Theorem,

height of the prism ^2 + 5.4^2 = 7.8^2

height of the prism = ±√(7.8^2 -5.4^2) = ±5.6285cm (5s.f.) (rej. - 5.6285 since height > 0cm)

volume of the prism = 1/2 x 5.4 x 5.6285 x 16 = 243cm^3 (3s.f.)

Order from least to greatest

inessss [21]

The order from the least to the greatest is $-\frac{26}{5}$ , $-5 . \overline{17}$ , $\sqrt{33}$ , and $\frac{37}{6}$ .

Step-by-step explanation:

Step 1:

We must determine each of the individual values to be able to arrange the given numbers.

$\frac{37}{6} = 6.166666,$

$-5 . \overline{17}$ means that so 1 and 7 in the decimal keep repeating so,

$-5 . \overline{17} = -5.17171717.$

$\sqrt{33} = 33^{\frac{1}{2} } = 5.7445,$ and

$-\frac{26}{5} = -5.2.$

Now that we have all the four values, we can arrange them in ascending order.

Step 2:

There are two negative numbers, the greater a negative number the lesser it is i.e. $-6 < -5.$

So the least value is $-\frac{26}{5}$ which is followed by $-5 . \overline{17}$ .

The other two are positive numbers. As $5.7445 > 6.1666$ so the highest number is $\frac{37}{6}$ .

So the order from the least to the greatest is $-\frac{26}{5}$ , $-5 . \overline{17}$ , $\sqrt{33}$ , and $\frac{37}{6}$ .

If two samples are selected from the same population, under what circumstances will the two samples have exactly the same t stat

WARRIOR [948]

If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean

The t-statistic is the ratio of the departure of the estimated value of a parameter from its hypothesized value to its standard error.

Variance is the expectation of the squared deviation of a random variable from its population mean or sample mean.

Mean is the average of the given numbers and is calculated by dividing the sum of given numbers by the total number of numbers

Hence, If two samples are selected from the same population, the two samples have exactly the same t statistics if the samples are same size and have the same variance and mean
