Answer: The area is 1296

Explanation: You want to take 1,296 as the perimeter and divide it by 9 as she walked around it 9 times. From there plug the answer (144) into the equation to find a area and you get 1296

Bryson and lilly played a game of darts and lilly scored 4 more the Bryson the total of the score was 180 how many points did ea
ki77a [65]
Well, we know that Lilly scored 4 more points than Bryson. So we could write that 
<span>Lilly's score = Bryson's score plus 4. Or L=B+4 Now we also know that </span>
<span>Lilly's score + Bryson's score = 180. So L+B=180 Now We can substitute in L in the second equation to get B+B+4=180 so B+B=176 and B=88 The we put B into the first equation and find that </span>
<span>L=92.</span>

PLEASE HELP!!!!
Bogdan [553]

Answer:

Step-by-step explanation:

We would apply the formula for binomial distribution which is expressed as

P(x = r) = nCr × p^r × q^(n - r)

Where

x represent the number of successes.

p represents the probability of success.

q = (1 - r) represents the probability of failure.

n represents the number of trials or sample.

From the information given,

p = 18% = 18/100 = 0.18

q = 1 - p = 1 - 0.18

q = 0.82

n = 5

Therefore,

P(x ≤ 2) = p(x = 0) + p(x = 1) + p(x = 2)

P(x = 0) = 5C0 × 0.18^0 × 0.82^(5 - 0)

P(x = 0) = 0.37

P(x = 1) = 5C1 × 0.18^1 × 0.82^(5 - 1)

P(x = 1) = 0.41

P(x = 2) = 5C2 × 0.18^2 × 0.82^(5 - 2)

P(x = 2) = 0.18

Therefore,

P(x ≤ 2) = 0.37 + 0.41 + 0.18 = 0.96

Graph 25 = -5y -3x using the slope and y-intercept
wlad13 [49]

Step-by-step explanation:

you move -5y to the other side.

25=-5y-3xsubtract 25 both sides

0=-5y-3x-25then add 5y both sides

5y=-3x-25divide 5 both sides

y=-3/5x-5

m=-3/5 do rise over runrise/run

b=(0,-5)plot it

3 down and 5 to right or 3 up and 5 left

Which point is Not on a circle with a center of (0,0) and a radius of 10?
Burka [1]
It is A because the radius is 10 which means that if x=0 then y must equal 10. (0,5) would be inside of the circle. If this doesn't make sense graph the circle and the points and you'll see what I mean.
