area of trapezoid with dimensions  b_1 = 4\frac{1}{4} , b_2 = 3\frac{3}{4}, h = 2\frac{1}{2}  is Area =10in^2 .

<u>Step-by-step explanation:</u>

We know that area of trapezoid is , area = (\frac{a+b}{2} )h , where a & b are bases and h is height . We have , b_1 = 4\frac{1}{4} , b_2 = 3\frac{3}{4}, h = 2\frac{1}{2} .

Area = (\frac{a+b}{2} )h

⇒ Area = (\frac{a+b}{2} )h

⇒ Area = (\frac{b_1+b_2}{2} )h

⇒ Area = (\frac{4\frac{1}{4} +3\frac{3}{4}}{2} )(2\frac{1}{2} )

⇒ Area = (\frac{\frac{17}{4} +\frac{15}{4}}{2} )(\frac{5}{2} )

⇒ Area = (\frac{\frac{17+15}{4}}{2} )(\frac{5}{2} )

⇒ Area = (\frac{\frac{32}{4}}{2} )(\frac{5}{2} )

⇒ Area = (\frac{8}{2} )(\frac{5}{2} )

⇒ Area = (\frac{40}{4} )

⇒ Area =10in^2

Therefore, area of trapezoid with dimensions  b_1 = 4\frac{1}{4} , b_2 = 3\frac{3}{4}, h = 2\frac{1}{2}  is Area =10in^2 .

Answer:

Mean = 30516.67

Standard deviation, s = 3996.55

P(x < 27000) = 0.0011518

Step-by-step explanation:

Given the data:

28500 35500 32600 36000 34000 25700 27500 29000 24600 31500 34500 26800

Mean, xbar = Σx / n = 366200 /12 = 30516.67

Standard deviation, s = [√Σ(x - xbar) / n-1]

Using calculator, s = 3996.55

The ZSCORE = (x - mean) / s/√n

Zscore = (27000 - 30516.67) / (3996.55/√12)

Zscore = - 3516.67 / 1153.7046

Zscore = - 3.048

P(x < 27000) = P(Z < - 3.049) = 0.0011518

Dogs have sweat glands on their pads and nose.

Dogs have a smaller population than dogs.

Dogs sleep more than humans.

Dogs live for survival, not for fame, money, nor any other materialistic possessions.

Solve the linear system using substitution <br><br> y - 5 = x<br> 4x - y = 4
Agata [3.3K]

Step-by-step explanation:

X=y-5

Now,

4x-y=4

4(y-5)-y=4

4y-20-y=4

3y=24

Y=8

Substituting the value of y

8-5=x

X=3
