Answer: Arithmetic and 3

Step-by-step explanation:

12 - 9 = 3 9 - 6 = 3 The common difference is equal and is three and so it is an arithmetic sequence

12/9 = 4/3 9/6 = 3/2 The ratio is not equal so this is not a geometric sequence

The circumference of a circle is 28. Contained in that circle is a smaller circle with area 36π. A point is selected at random f

Marrrta [24]

Answer:

$Pr = \frac{9}{49}$

Step-by-step explanation:

Given

$d = 28$ --- big circle

$A_2 = 36 \pi$ --- area of small circle

Required

Probability that a point selected lands on the small circle

Calculate the area of the big circle using;

$A_1 = \pi r^2$

Where

$r = d/2$

So, we have:

$r = 28/2 = 14$

This gives:

$A_1 = \pi * 14^2$

$A_1 = \pi * 196$

$A_1 = 196\pi$

The probability that a point selected lands on the small circle is calculated by dividing the area of the small cicle by the big circle

This gives:

$Pr = \frac{36\pi}{196\pi}$

$Pr = \frac{36}{196}$

Simplify

$Pr = \frac{9}{49}$

If 3n + 2 = 14, what must 3n be equal to? 16 ,14, 4, 12

Andrew [12]

4 because 3 * 4 = 12 then add 2 and that would give you 14 so 4 is the answer

-21, -23, -27, -28, -28, -29 order them least to greatest and then find the middle if there is not a middle then put -27.5 as your answer for the median. For the mean add up all the number then you should get -156 then divide it by 6 which should give you -26 for the mean. and for the mode you should get -28 as the one that occurs the most often.

mean: -26

median: -27.5

mode: -28

Darryl received a special offer from the local grocery store on gourmet pickle buckets.The size of a pickle bucket is 640 ounces

Elodia [21]

We are given

For Downtown Deli:

The size of a pickle bucket is 640 ounces

so, total ounces =640

the price is only $32

so, total price =32

now, we can find price for each ounces

Price for each ounce = (total price)/(total ounces)

Price for each ounce is

$=\frac{32}{640}$

$=0.05$ $ / ounce

and we are given

The purchasing Brand D pickles at $0.20 per ounce

So, local grocery rate is cheaper

so, Darryl should accept special offer from the local grocery store on gourmet pickle buckets........Answer
