In a bag of counters, there are 3 times as many red counters as

Anni [7]

Answer:

The ratio is 6:2:1.

Step-by-step explanation:

Let's denote:

Blue counter b

Red counter r

Yellow counter y.

There is given

r=3b (three times more red as blue) [1]

and

b=2y (twice more blue as yellow.) [2]

Now, replacing [2] to [1] gives

3*2y=r

6y=r.

Hence, the ratio is 6:2:1, because r=6y and b=2y.

The table below shows the function f.

Dmitriy789 [7]

Answer:

A. 11

Step-by-step explanation:

The average rate of change of the given function over the interval [2,6] is simply the slope of the secant line connecting the point (2,f(2)) and (6,f(6)).

This implies that, the average rate of change over [2,6]

$=\frac{f(6)-f(2)}{6-2}$

$=\frac{f(6)-f(2)}{4}$

From the table f(6)=71

Since we want the average rate of change to be 15, we have;

$15=\frac{71-f(2)}{4}$

This implies that;

$4\times15=71-f(2)$

$60=71-f(2)$

$60-71=-f(2)$

$-11=-f(2)$

$11=f(2)$

The correct choice is A.
