Sample space for all possible outcomes:
HH, HT, TH, TT
Sample space for event where heads is the first toss:
HT, HH
Y=2 7x2= 14
X= 7 4x7=28
28-14=14
Answer:
Step-by-step explanation:
Area of one road = 700 x 10
7000 sq m
area of another road
= 300 x 10 = 3000sq m
Total area of road
= 7000 + 3000 - 10 x 10
= 9900 sq m
Area of park
= 700 x 300
= 210000 sq m
less area of road
= 210000 - 9900
= 200100 sq m
= 200100 / 10000 hectare
= 20.01 hectare.
Answer:
m<1 =95
m<2 = 130
Step-by-step explanation:
I take it you want the size of <1 and <2?
<ABC + 95 = 180 Same straight line.
<ABC = 180 - 95 Subtract 95 from both sides.
<ABC = 85 Combine
===========================
<1 + <ABC = 180 Interior angles on the same side of the transversal = 180
<1 + 85 = 180
<1 = 180 - 85
<1 = 95
=============================
Givens
<ABC = 85
m< 1 = 95
<ADC = 50 Given
m<2 = ?
m<2 + <ABC + m<1 + 50 = 360 The four angles of a quadrilateral add to 360
m<2 + 85 + 95 + 50 = 360
m<2 + 230 = 360
m<2 = 360 - 230
m<2 = 130
Answer:
Step-by-step explanation:
The total number of marbles is 17
Red
6/17 is the answer. As a decimal, that's .3529
Green
11/17 is the answer. As a decimal that's .6471
Purple
Since there are no purples, the answer is 0
Red or Green
This one is a little tricky.
What else is there besides red or green? Nothing. You have to choose 1 or the other.
The answer is 1.
