Answer:
The cost of 1 doll = $ 7.5
and The Cost of 1 toy train = $ 5
Step-by-step explanation:
Let the price of 1 doll = $ x
The price of 1 toy train = $ y
Now, according to the question:
6 x + 2 y = $ 55
and 4 x + 7 y = $ 65
Solving the given system of equation,
From (1), we get
or, solving for y , we get
110y - 4y + 21 y = 195
or, 17 y = 85
⇒ y= 85/17 = 5
This implies : 6 x + 2 (5) =55
or, 6x = 55 - 10 = 45
or, x = 45/ 6 = 15/2
Hence, the cost of 1 doll = x = $ 7.5
and the Cost of 1 toy train = y = $ 5
Answer:
A) amount of snowfall in a blizzard
Step-by-step explanation:
Both continuous and discrete data are quantitative.
The difference is that
- Continuous data can take any value. You obtain it by measurement.
- Discrete data can take only certain values. You obtain it by counting.
The amount of snowfall in a blizzard is continuous data. It can take any value such as 100.3 cm or 250.5 cm
.
B) is wrong. The number of students who pass a math quiz is discrete data. You can't have half a student.
C is wrong. The number of languages an individual speaks is discrete data. You can't speak half a language.
D) is wrong. The number or treadmills in a gym is discrete data. You can't have half a treadmill.

Answer:
So a square is a special kind of rectangle, it is one where all the sides have the same length. Thus every square is a rectangle because it is a quadrilateral with all four angles right angles. However not every rectangle is a square, to be a square its sides must have the same length.
Hope this helps!
Answer:
y - 5 = 2(x + 2)
General Formulas and Concepts:
Point-Slope Form: y - y₁ = m(x - x₁)
x₁ - x coordinate
y₁ - y coordinate
m - slope
Step-by-step explanation:
<u>Step 1: Define</u>
Slope <em>m</em> = 2
Point (-2, 5)
<u>Step 2: Create equation</u>
y - 5 = 2(x + 2)
