Answer:
<u>The expression is t = 0.2 + 1.3p, where t is the total weight of the box and p the number of plaques inside the box</u>
Step-by-step explanation:
1,. Let's review the information provided to us to answer the question correctly:
Weight of a box by itself = 0.2 kilograms
Weight of a plaque = 1.3 kilograms
2. Which expression can be used to determine the total weight of the box?
For answering the question, we will use the following expression:
Total weight of the box in kilograms = t
Number of plaques inside the box = p
t = 0.2 + 1.3p
<u>The expression is t = 0.2 + 1.3p, where t is the total weight of the box and p the number of plaques inside the box.</u>

Answer:
A <u>z-score</u> indicates how far an individual raw score falls from the mean of a distribution; the <u>standard deviation</u> indicates how the scores in general scatter around the mean.
Step-by-step explanation:
We have been given an incomplete statement. We are supposed to complete the given statement.
We know that z-score of a data set indicates that a sample score or raw score is how many standard deviation away from the mean. Z-score indicates the distance of a raw score is above or below mean in units.
Therefore, the correct word for 1st blank would be "z-score".
We also know that standard deviation represents the variation of a data set. It tells that data points of a data set are how much close or away from mean of the data set.
Therefore, the correct word for 2nd blank would be "standard deviation".

Answer:
- 15 @ 41 cents
- 50 @ 56 cents
Step-by-step explanation:
Let x represent the number of 41-cent stamps Yumi bought. Then the number of 56-cent stamps she bought was 4x-10. Her total purchase was ...
0.41x +0.56(4x -10) = 34.15
2.65x -5.60 = 34.15 . . . . . . . eliminate parentheses, collect terms
2.65x = 39.75 . . . . . . . . . . . . add 5.60
x = 15 . . . . . . . . . . . . . . divide by 2.65
4x-10 = 50
Yumi bought 15 41-cent stamps and 50 56-cent stamps.
