A program to simulate coin tosses is used to simultaneously toss 1,000 coins. If the number of heads displayed in 5 trials of the simulation total 528, 486, 492, 545, and 505, what is the experimental probability of getting heads on a coin toss? Round your answer to the nearest percent.

step-by-step explanation:

given perimeter: 28cm

length: 9cm

atp,

2(l+w)=p of the reactangle

2(9+x)=28

18+2x=28

2x=28-18

x=10/2

x=5

therefore width is 5 cm

b. y = 4x - 2

step-by-step explanation:

to find a parallel equation to an equation, make sure both equations have the same slope but different y-intercepts.

y = 4x + 1

4 = slope

1 = y-intercept

y = 4x - 2

4 = slope

-2 = y-intercept

they both have the same slope but different y-intercepts, so, b. is the correct answer.

and to check your work, you can graph both equations. : )

answer: 12   they all have at least 28 days

step-by-step explanation: haha

but there’s no any figure there!
