Answer:
one pound of apple cost $2.5
Step-by-step explanation:
Let the amount they both spent at the grocery store be y and x be the price of apples per pound.
Since Tara bought 5 pounds of apples, 5x = y (1) and Ashley bought 3 pounds of apples and $5 worth other groceries, 3x + 5 = y (2).
Equating both expressions, 5x = 3x + 5
collecting like terms,
5x - 3x = 5
2x = 5
dividing both sides by 2, we have
x = 5/2
x = 2.5
So one pound of apple cost $2.5
Answer:
(1) B
(2) A
(3) C
Step-by-step explanation:
A random variable is a variable that denotes a set of all the possible outcomes of a random experiment. It is denotes by a single capital letter such as X or Y.
There are two types of random variables.
- Discrete random variable: These type of random variable takes finite number of values, such as 0, 1, 2, 3, 4, ... For example, number of girl child in a neighborhood.
- Continuous random variable: These type of random variables takes infinite number of possible values. For example, the height, weight.
(1)
Exact weight of quarters now in circulation in the United States.
The variable weight is a continuous variable.
Thus, the exact weight of quarters now in circulation in the United States is a continuous random variable.
(2)
Shoe sizes of humans.
The shoe size of a person are discrete and finite values.
Thus, the shoe sizes of humans are discrete random variables.
(3)
Political party affiliations of adults in the United States.
This variable is not a quantitative variable.
It is a qualitative variable.
Thus, the political party affiliations of adults in the United States is no random variable.
Answer:
all
Step-by-step explanation:
all of them has the probability
Is there a picture to go with it?
Given:
The coordinates of a point are (-3,-6).
To find:
The point on the coordinate plane whose coordinates are (-3,-6).
Solution:
From the given information of coordinate plane, it is clear that
Coordinates of point A are (-3, 6).
Coordinates of point B are (-6,-3)
Coordinates of point C are (-3,-6)
Coordinates of point D are (3,-6)
It is clear that, only point C has coordinates (-3,-6).
So, the required point is C.
Therefore, the correct option is C.
