Mathematics

Minchanka [31]3 years ago

Answer:

80 units

Step-by-step explanation:

The star has 10 sides. If each side is 8 units, then the perimeter is 10(80) because the perimeter is the sum of the lengths. With each length being 8, you could add 8 to itself 10 times, but it is faster to multiply.

Ksenya-84 [330]

Answer:

0.5676

Step-by-step explanation:

We have been given these informations from this question ,

probability of 4% = 0.04

q = 1 - p = 1 - 0.04 = 0.96

Sample size n = 60

We solve further by Using binomial probability formula,

P(X = x) = (nCx)*px*(1 - p)^n - x

We have:

(60C0)x 0.04⁰x(0.96⁶⁰+(60C1)x0.04¹x(0.96)⁵⁹+(60C2)x0.04²x (0.96)⁵⁸

From this we would get the probability to be = 0.5676

Calcula el área y perímetro de un rectángulo que tiene como base (x+y) y altura (x-1).
nignag [31]

Answer:

A = x^2 - x + xy - y

P = 4x + 2y - 2

Step-by-step explanation:

a = (x + y)(x - 1) \\ a =  {x}^{2}  - x + xy - y \\  \\ p = 2((x + y) + (x - 1)) \\ p = 2(2x + y + - 1) \\ p = 4x + 2y - 2

I hope that is useful for you :)

Which of the following represents the y-intercept of the equation y = 2x - 5 A. 2 B. -5 C. 0 D. 5
lora16 [44]

Hello :)

the y intercept can be found when you use the slope intercept formula

<h2>y = mx +b</h2>

m: slope

b: y-intercept

In the equation given here:

<h2>y = 2x - 5 </h2>

m: 2

b: -5

So, therefore the answer is B. -5
