Classify ABC by its angles when mA = 32°, mB = 95°, and mC = 53°.

Since none of the angles equal 90 degrees, it cannot be a right angle.
No two angles are the same measurement, it is not straight.
All three of the angle are not less than 90 degrees it would not be acute.
Since 1 of the angles is over 90 degrees, it would be an OBTUSE angle.

Which ordered pair is a solution of the equation y equals x minus 3

Rom4ik [11]

Y = x-3

Basically you just need to plug in an x value and solve for y
y = x - 3
y = (4) - 3
y = 1

In this case, the ordered pair of this equation would be (4, 1)

You can do this given any x or y coordinate

Hope this helps

The director of the library believes that 14% of the library's collection is checked out. If the director is right, what is the

Ksivusya [100]

Answer: 0.2643

Step-by-step explanation:

Let p be the population proportion and $\hat{p}$ be the sample proportion .

As per given question , we have

$p=0.14\\\\ \hat{p}=0.13\\\\ n=478$

z-score : $\dfrac{\hat{p}-p}{\sqrt{\dfrac{p(1-p)}{n}}}$

$z=\dfrac{0.13-0.14}{\sqrt{\dfrac{0.14(1-0.14)}{478}}}\\\\=-0.630087269176\approx-0.63$

The required probability ( using z-table ):-

$P(z$

Hence, the probability that the proportion of books checked out in a sample of 478 books would be less than 13% = 0.2643
