Answer:

-2/7

Step-by-step explanation:

We can use the slope formula

m = ( y2-y1)/(x2-x1)

    = ( 1-3)/( 3 - -4)

    = (1-3)/( 3+4)

    = -2/7

Cole said that 555 rounded to the nearest ten is 600. What's coles error?
ki77a [65]
Cole's mistake was that he rounded 555 to the nearest hundred instead of the nearest ten. He should've rounded it to 560 because the tens place is the second number, not the first one.

QUESTIONS The average price of wheat per metric ton in 2012 was $30575. Demand in millions of metric tons) in 2012 was 672. The
soldi70 [24.7K]

Answer:<u> -0.9 ; inelastic</u>

Explanation:  

Given:

The average price of wheat per metric ton in 2012 = $305.75

Demand (in millions of metric tons) in 2012 = 672

The average price of wheat per metric ton in 2013 =  $291.56

Demand (in millions of metric tons) in 2013 = 700

We will compute the elasticity using the following formula:

ε = \frac{\frac{(Q_{2} - Q_{1})}{\frac{(Q_{2} +Q_{1})}{2}}}{\frac{(P_{2} - P_{1})}{\frac{(P_{2} +P_{1})}{2}}}

ε = \frac{\Delta Q}{\Delta P}

Now , we'll first compute  \Delta Q

i.e.  \frac{\Delta Q}{\Delta P} = \frac{(700 - 672)}{\frac{(700 +672)}{2}}

\Delta Q = 0.04081

Similarly for  \Delta P

i.e. \Delta P = \frac{(291.56 - 305.75)}{\frac{(261.56 +305.75)}{2}}

\Delta P = -0.0475

ε = \frac{0.04081}{-0.0475}

ε = -0.859 \simeq -0.9

\because we know that ;

If, ε > 1 ⇒ Elastic

ε < 1 ⇒ Inelastic

ε = 1 ⇒ unit elastic

<u><em>\because Here , ε = -0.859 \simeq -0.9 </em></u>

<u><em>Therefore ε is inelastic.</em></u>

This scatter plot shows the number of baskets made and the time in minutes that has passed.
irina1246 [14]

Scatter plots are used to relate variables using scattered dots.

The best prediction for the number of baskets made in 16 minutes is (c) 14 baskets

From the graph, we can see that the number of baskets made in 14 minutes is 12.

Also, from the graph; as the minutes increases, the number of baskets either remain the same or increases.

This means that, for 16 minutes, the number of baskets would either be 12 (same as 14 minutes) or greater.

The closest to 12 baskets in the option is 14.

Hence, the best prediction for the number of baskets made in 16 minutes is (c) 14 baskets
