Answer:

It is median.

Step-by-step explanation:

a) The mean is the average of all the numbers: (81+87+93+89+61+81)/6= 82

b) The median is the middle value when the numbers are arranged in ascending order.

61,81,81,87,89,93

since it's an even number, we take the two middle numbers, in our case 81+87=168/2=84

c) The mode is the most frequent data, which in our case is 81

d) It would be the median because it has the highest grade he could get from the other options.

Answer:

Jack should use the Median

Step-by-step explanation:

The median is the numbers in the middle of the list of numbers.

81, 87, 93, 89, 61, 81

93, and 89 are the highest numbers, and they're in the middle, so therefore the median is the best option.

if we use the mean we get 82 for the test scores.

and the mode would only be 81.

Step-by-step explanation:

From question we are told that

   The  population in the first year is  y_1 =  146

     The  population in the next year is  y_2 =  183

Generally the growth rate is mathematically represented as

    g  =  \frac{y_2 - y_1 }{y_1}  *  100

    g =  \frac{183 - 146}{146}  *100

    g =  25.3 \%

How do you multiply
vodomira [7]

You multiply using the multiplication table. Multiplication is one of the four basic operations in arithmetic, along with addition, subtraction, and division. Multiplication can actually be considered repeated addition, and you can solve simple multiplication problems by adding repeatedly. For larger numbers, you'll want to do long multiplication, which breaks the process down into repeated simple multiplication and addition problems. You can also try a shortcut version of long multiplication by splitting the smaller number in the problem into tens and ones, but this works best when the smaller number is between 10 and 19.
