Answer:
Step-by-step explanation:
Experimental probability is the number of specific outcomes divided by the total number of trials.
P(6)=6/29
Answer:
Step-by-step explanation:
We aren't told what the 1, 2, 3, 4 represent. If it is number of children, then the question makes no sense. We have to assume it is probably hours.
dollars/hours = 15/1 = 30/2 = 45/3 = 60/4 = $15/h
The rate is a constant, so amount is proportional to hours.
Answer:
40
Step-by-step explanation:
Given problem:
x² - y²
x+ y = 10
x - y = 4
Solution:
Using the concept of differences of two squares;
x² - y² = (x + y)(x - y)
So;
x² - y² = 10 x 4 = 40
Answer:
46 units²
Step-by-step explanation:
The figure can be decomposed into 2 triangles and a rectangle.
Area of rectangle = L*W
W = 4
L = 8
Area = 32 units²
Area of triangle 1:
Area = ½(b*h)
b = 3
h = 4
Area = ½*3*4
Area = 6 in.
Area of triangle 2:
b = 4
h = 4
Area = ½*4*4
Area = 8 units
✅Area of the figure = 32 + 6 + 8
= 46 units²
