Answer:
-2 1/2
Step-by-step explanation:
The first thing to do here is turn 8 3/4 and -3 1/2 into fractions(we will convert to mixed number at the end). So you get: 35/4 and -7/2.
That gives you (35/4)/(-7/2).
Then you use keep change flip to simplify this.
(35/4) * -2/7 = 2.5
2.5 as a mixed number is:
-2 1/2
Answer:
What are the numbers?
Step-by-step explanation:
Euclid's fifth postulate states, rather wordily, that:
<em>if a straight line falling on two straight lines make the interior angles on the same side less than two right angles, </em><span><em>the two straight lines, if produced indefinitely, meet on that side </em><em>on</em><em> which are the angles less than the two right angles.
</em></span>
<em />If that sounds like a mouthful to you, you're not alone. Geometers throughout history found that postulate incredibly awkwardly-worded compared with his other four, and many in the 19th century rejected it outright and created a number of interesting new geometries from its ashes.
Euclid's fifth, put another way, states that two lines that aren't parallel will eventually meet, which consequently implies that <em>two parallel lines will never meet</em>. Without intending it, this property defines the space of Euclid's geometry to be
<em>an infinite flat plane</em>.
If we take that parallel postulate and
throw it out<em>, </em>then we've defined a <em>spherical space</em> for our geometry. Now, it doesn't matter where we draw our lines; <em>all of them will meet at some point</em>. If you need any convincing of this, take a look at the attached image. The longitude lines <em>seem </em>parallel at first, but they all eventually meet at the north and south poles.
Answer:
0.68
Step-by-step explanation:
$17 out of $25 comes to 17/25, or 0.68. This is the desired decimal equivalent.
Answer: Statistical inference
Step-by-step explanation:
Statistical inference is the process of making conclusions about population from the sample.
Here, 1,600 registered voters is just a sample which is used to represent the entire population, so the proportion of of all voters approve of the President is representing a statistic .
On absence of complete information of the population the statistic is the the measure to represent entire population and this is a part of statistical inference.
Hence, the statement is an example of "statistical inference."
