Answer:

80 dollars.

Step-by-step explanation:

To calculate this we just create a simple equation, where the total will be represented by x, so total will equal the remaining money + the spent money:

Total= Remaining `+ Spent

X=$44+ $36

x= $80

So the origina amount in the gift card was $80.

The average mark of candidates in an aptitude test was 128.5 with a standard deviation of 8.2.Three scores extracted from the te
Luba_88 [7]

Answer:

102

Step-by-step explanation:

We have the mean (m) 128.5 and the standard deviation (sd) 8.2, we must calculate the value of z for each one and determine whether or not it is an outlier:

z = (x - m) / sd

In the first case x = 148:

z = (148 - 128.5) /8.2

z = 2.37

In the second case x = 102:

z = (102 - 128.5) /8.2

z = -3.23

In the first case x = 152:

z = (152 - 128.5) /8.2

z = 2.86

The value of this is usually between -3 and 3, therefore when x is 102 it goes outside the range of the value of z, which means that this is the outlier.

The illustration below shows the graph of yyy as a function of xxx.
Alisiya [41]
  1. The slope of the graph of the function is equal to 0 for x between x = -3 and x = -2.
  2. The slope of the graph of the function is equal to 0 for x between x = 3 and x = 4.
  3. The greatest value of y is y = 4.
  4. The smallest value of y is y = -3.

<h3>How to complete the sentences?</h3>

By critically observing the graph shown in the image attached below, we can logically deduce that the slope of the graph of this function is equal to 0 for x, between x = -3 and x = -2.

Similarly, the slope of the graph of this function is also equal to 0 for x, between x = 3 and x = 4.

Based on the graph (see attachment), the greatest value of y is 4 while the smallest value of y is -3.

Here is an addition sentence.
kiruha [24]

Answer: B. 3+(1+11)=15


Step-by-step explanation:

1. By definition, the associative property of addition is:

(a+b)+c=a+(b+c)

2. Therefore, if you have the following expression:

(3+1)+11=15

You apply  the Asociative property of addition by regrouping the numbers as following:

3+(1+11)=15

3. Then, you can conclude that the correct option is B.
