Answer should be A
Explanation: i’m learning it rn and Experimental probability is the result of an experiment. Theoretical probability is what is expected to happen.
Answer:
5
Step-by-step explanation:
570000/5.7 is 100000
100000 is 10^5
Ok so this is conic sectuion
first group x's with x's and y's with y's
then complete the squra with x's and y's
2x^2-8x+2y^2+10y+2=0
2(x^2-4x)+2(y^2+5y)+2=0
take 1/2 of linear coeficient and square
-4/2=-2, (-2)^2=4
5/2=2.5, 2.5^2=6.25
add that and negative inside
2(x^2-4x+4-4)+2(y^2+5y+6.25-6.25)+2=0
factor perfect squares
2((x-2)^2-4)+2((y+2.5)^2-6.25)+2=0
distribute
2(x-2)^2-8+2(y+2.5)^2-12.5+2=0
2(x-2)^2+2(y+2.5)^2-18.5=0
add 18.5 both sides
2(x-2)^2+2(y+2.5)^2=18.5
divide both sides by 2
(x-2)^2+(y+2.5)^2=9.25
that is a circle center (2,-2.5) with radius √9.25
Answer:
y=3(x+4)²+2
Step-by-step explanation:
Answer:
7.20
Step-by-step explanation:
triangle is right triangle so other leg of first is 12
5 x 3/5 = 5, so
do 12 x 3/5 to get 7.20
