Answer:

Step-by-step explanation:

the answer is 15 because a triangle has to equal 180 so all you have to do is add 81 and 84 then subtract 180 from it. like this 81+84=165 180-165=15. Hope this helps.

$\frac{3(-\frac{1}{2})(4)^{2} - (-3)^{3}}{-\frac{1}{2}}$

$\frac{3(-\frac{1}{2})(16) + 27}{-\frac{1}{2}}$

$\frac{3(-8) + 27}{-\frac{1}{2}}$

The answer is B.

$\frac{-24 + 27}{-\frac{1}{2}}$

$\frac{3}{-\frac{1}{2}}$

Match the vocabulary word with its definition.

mote1985 [20]

1. the most frequently occurring number(s) in a set of data ⇒ Mode

2. the smallest and largest values in a data set ⇒ Extreme values

3. the smallest value in a data set ⇒ Minimum

4. the difference between the largest and smallest data points ⇒ Range

5. the largest value in a data set ⇒ Maximum

6. the middle value of a set of data arranged in numerical order ⇒ Median

<u>Step-by-step explanation:</u>

The term "Minimum" is defined as the smallest value in the data set.

For example : Consider a data set {1,2,3,4,5}.
Here, the minimum is 1.

The term "Maximum" is defined as the largest value in the data set.

For example : Consider a data set {1,2,3,4,5}.
Here, the maximum is 5.

The term "Range" is defined as the difference between the largest and smallest data points in the data set.

For example : Consider a data set {1,2,3,4,5}.
To find the range : (Largest value - smallest value).
Range ⇒ 5 - 1 = 4. Here, the Range is 4.

The term "Median" is the middle value of the set data after arranging it in the ascending order.

For example : Consider a data set {6,3,2,4,1,5}.
To find the Median : Arrange the data set in the ascending order.
Therefore, the modified data set is {1,2,3,4,5,6}.
Now, the middle term in the above data set is 4.

The term "Mode" is defined as the most repeated numbers in a data set.

For example : Consider a data set {1,2,4,4,5}.
To find the Mode : look for the most repeated number in the data set.
Here, the number 4 is repeated two times. Therefore, mode is 4.

The term "extreme values" is defined as the smallest and the largest values in a data set.

For example : Consider a data set {11,13,15,17,19}.
To find the extreme : Find the smallest value in the data set and also find the largest value in the data set.
Therefore, the extreme values are 11 and 19.

Aggie is an australian exchange sudent in china, and she currenly has 14,000 yuan in her bank account. If the exchange rate chan

Alenkasestr [34]

Step-by-step explanation:

Amount in Aggie bank account = 14,000 yuan

Initial exchange rate:

1 Australian dollar = 6.21 yuan

Initial amount in Australian dollars will be;

x aus dollar = 14,000 yuan

cross multiply

6.21x = 14,000

x = 14,000/6.21

x = 2,254.428 australian dollars

If the exchange rate increases to 6.37 Chinese yuan, her new balance in Australian dollars will be y;

1 Australian dollar = 6.37 yuan

y Australian dollar = 14,000 yuan

cross multiply

6.37y = 14,000

x = 14,000/6.37

y = 2,197.80 Australian dollars

The change in her account balance due to increase in exchange rate is y-x

y-x = 2,197.80 - 2,254.428

y-x = -56.626 aus dollars

This negative values shows a decrease in her account balance by 56.626 aus dollars due to increase in the exchange rate.
