Find the value of x if ∡A and ∡B are supplementary angles.

Elanso [62]

Answer:

$x = 30.5$

Step-by-step explanation:

Two angles are supplementary when they add up to 180°.

So we know that:

$C + D = 180$

Supplanting we get:

$(3x-44) + (5x-20) = 180$

We add up the X's.

$8x-44-20 = 180$

$8x-64 = 180$

Then we send 64 to the other side adding:

$8x = 180+64$

$8x = 244$

And then the 8 goes dividing:

$x = 244 : 8$

$x = 30.5$

The average age in a sample of 190 students at City College is 22. As a result of this sample, it can be concluded that the aver

m_a_m_a [10]

Answer:

The true mean $\mu$ it probably could be larger, smaller, or equal to 22

Step-by-step explanation:

False.

By definition the sample mean is defined as:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}$

For this case the value for the sample size is n =190 and the calculated sample mean is $\bar X=22$ . This value represent the sample and for this case we can't assume that this value represent at all the population as the population mean $\mu$ since we probably have variability from the data of the students at City College.

So we can conclude that the true mean $\mu$ it probably could be larger, smaller, or equal to 22

HELP ASAP

dalvyx [7]

So,

All we have to do is multiply all three dimensions together.

First, convert all fractions into improper fractions.

$3 \frac{1}{5}--\ \textgreater \ \frac{16}{5}$

$1 \frac{3}{4} --\ \textgreater \ \frac{7}{4}$

$2 \frac{1}{4} --\ \textgreater \ \frac{9}{4}$

Now multiply the fractions together.

<span> $\frac{16}{5}*\frac{7}{4}*\frac{9}{4}= \frac{2*2*2*2*3*3*7}{2*2*2*2*5}$
</span>
$\frac{3*3*7}{5}--\ \textgreater \ \frac{63}{5}\ or\ 12 \frac{3}{5}\ ft.^3$

The correct option is C.
