Answer:

The blue and yellow macaw is 33 inches long.

Step-by-step explanation:

If the toucan is 22 inches long and it's two thirds the length of the macaw you can divide by two to find what one third is.

22 ÷ 2 = 11

So then you have to multiply by 3 to find what the full length is.

3 x 11 = 33 inches

Hope that helps and have a great day!

Answer:

33 in

Step-by-step explanation:

Let the length of the macaw be x
The length of the toucan is 22 in

<u>Then we have equation</u>

x*2/3 = 22
x = 22 ÷ 2/3
x = 22*3/2
x = 33 in

Blue-and-yellow macaw is 33 in long

Find the area of the region bounded by the y-axis, x-axis and the line y=-2x+4.

Anna007 [38]

Answer:2

Step-by-step explanation:y = 0 : 0 = -2x + 4 → x = -2 is the x-intercept. Similarly, when the line crosses the y-axis, the x-coordinate at this point will be zero and substituting x = 0 into the equation will give us the y-intercept. x = 0 : y = 0 + 4 → y = 4 is the y-intercept.

HELP PLEASE 18 POINTS

ICE Princess25 [194]

Answer:

Step-by-step explanation:

line 1 m=y2-y1 / x2-x1 [formula for slope ]

m= 0 - (-3) / 8-(-4)

m= 3 /12

m= 1/4 slope of line 1

line2

m = 2-6 / 0-(-1)

m = -4 / 1

m = -4 slope of line 2

line 3

m = -4 - (-7) / -3 - 6

m = 3 / -9

m = - 1/3 slope of line 3

lines 1 & 2 perpendicular b/c they are reciprocals with a sign change :)

lines 1 & 3 neither.. differet slopes and not reciprocals

lines 2 & 3 perpendicular b/c they are reciprocals with a sign change :)

The probability mass function of X is f(x)= 1/6, x 1.2...,6 then find out the value

Mumz [18]

For the given probability mass function of X, the mean is 3.5 and the standard deviation is 1.708.

A discrete random variable X's probability mass function (PMF) is a function over its sample space that estimates the likelihood that X will have a given value. f(x)=P[X=x].
The total of all potential values for a random variable X, weighted by their relative probabilities, is known as the mean (or expected value E[X]) of that variable.
Mean(μ) = 1(1/6) + 2(1/6) + 3(1/6) + 4(1/6) + 5(1/6) + 6(1/6).
Mean(μ) = (1+2+3+4+5+6)/6
Mean(μ) = 21/6
Mean(μ) = 3.5
The square root of the variance of a random variable, sample, statistical population, data collection, or probability distribution represents its standard deviation. It is denoted by 'σ'.
A random variable's variance (or Var[X]) is a measurement of the range of potential values. It is, by definition, the squared expectation of the distance between X and μ. It is denoted by 'σ²'.
σ² = E[X²]−μ²
σ² = [1²(1/6) + 2²(1/6) + 3²(1/6) + 4²(1/6) + 5²(1/6) + 6²(1/6)] - (3.5)²
σ² = [(1² + 2²+ 3² + 4²+ 5²+ 6²)/6] - (3.5)²
σ² = [(1 + 4 + 9 + 16 + 25 + 36)/6] - (3.5)²
σ² = (91/6) - (3.5)²
σ² = 15.167-12.25
σ² = 2.917
σ = √2.917
Standard deviation (σ) = 1.708
