First of all, we know that Dianna has total 6+5+4=15 coins including: 6 quarters, 5 dimes and 4 nickles in her purse.
P(grabbing the first dimes):
5/15 or 1/3
P(grabbing the second dimes):
5/15 or 1/3
P(grabbing 2 dimes in a row):
1/3*1/3=1/9. As a result,the probability that Diana grabs 2 dimes is 1/9. Hope it help!
Answer:
O
Step-by-step explanation:
Answer:
B ( -1,-7)
A (-3,-2)
C (6, -1)
Step-by-step explanation:
<u>Explanation</u>:-
Given vertices are A( -3,2) , B(-1,7) and C(6,1)
Reflection about the x-axis then the coordinate points are transformed to
(x,y)→ (x,-y)
A(-3,2)→ A¹(-3,-2)
B(-1,7)→ B¹(-1,-7)
C(6,1)→ C¹(6,-1)
The formula for circumference is C = 2πr, where r is the radius of the circle. However, the radius is half the diameter, so the circumference could also be calculated using the formula C = πd, where d is the diameter of the circle. π is commonly shortened to 3.14.
If the diameter of the circle is 6 feet, an estimate of the circle's circumference is 6 times 3 feet or 18 feet.
Answer:
18 ft
Just subisute values that will work
one easy way is to make one sides equal to only one of the placeholders, like y, and then lug in values in for x exg
x+2y=3
subtract x from both sides
2y=3-x
divideb bith sides by 2
y=-1/2x+3
subsitute valudes for x and get values for y
if x=2 then
y=-1/2(2)+3
y==-1+3
y=2
when x=2, y=2
when y=0 then y=3
