Answer:

Unit rate so, B

Step-by-step explanation:

The unit rate is basically a ratio between two different units

So when we divide 300 by 3, 300/3, we get 100 and that is the unit rate.

It's not the origin because the origin is the starting point and the coordinate plain, is well, a coordinate plain!

So for these problems you just need to get all x values on one side of the equal sign. Since this has just an x and not other x values we can leave the x there on the left. Now subtract 5 on both sides to get rid of the 5 on left side of the equals sign. Subtract 5 on the right side too because anything that you do on the left side, you do on the right side as well. It should look like this now:

$x+5=7\\ \\ x=7-5\\ \\ x=2$

Hope this helps!

Is the following relation a function? Graph of x equals y squared, which results in a horizontal parabola centered on the x axis

Rus_ich [418]

It is not a function.

For any positive x this graph will give two different values y, and that is not allowed to happen for functions.

Rasberry Crazy Ants, a species found in wall sockets, cellphones, and television sets are

marishachu [46]

The average time taken to travel to Toronto by the swarm of Rasberry Crazy Ants is 12,947 Years

<h3>What is the calculation for the above Solution?</h3>

To arrive at the solution above, we need to look at the information given and the information assumed.

Step 1 - Information given:

The swarm are currently at Austin, Texas
The swarm move at an average speed of 1.8feet/day

Step 2 - Information assumed:

The swarm are travelling to the location of the student which is assumed to be Toronto.

Hence,

Time taken for the swam to get to Toronto (TTS) =

Distance between Austin, Texas and Toronto (DBTT) / Average distance covered per day by the Rasberry Ants. (ADC)

Estimated distance between Austin Texas and Toronto = 2592.6 Kilometers

Time travelled per day by the ants (In Km) = 0.00054864

Thus,

TTS = DBTT/ADC

= 2592.6 /0.00054864

≈ 4,725,503.06 days or

≈ 12,947 Years

<h3>Do I need to be worried about these ants infesting your cellphone or television? Do you need to worry for your children? For your grandchildren?</h3>

The answer to both questions is NO.

The average life expectancy in Toronto (as at 2022) is 80 years. Assuming I was born today, it is expected that the time between now and when my last grand child will die is about:

80 x 3 = 240 years.

Given that the ants have to travel 12,947 to get to Toronto, the possibility of my grand children seeing them is zero.

Besides, even if they by chance got to Toronto and infested my grandchildren's residence, they would have nothing to worry about because Rasberry Crazy Ants are 100% harmless.

Answer:

6.1568 to 1

A Democrat is 6.1568 more likely to respond "yes" than a Republican

Step-by-step explanation:

From the provided data, the following relationships can be modeled:

$D=2.96I\\I =2.08R$

Combining the information to compare democrats to republicans:

$D=2.96*2.08R\\D=6.1568R$

The estimated odds of a yes response for a Democrat was 6.1568 times higher than for a Republican. This means that a Democrat is 6.1568 more likely to respond "yes" than a Republican.
