Answer:

68cm^2

Step-by-step explanation:

<h2>A trapezium is a type of quadrilateral with the two opposite sides parallel.</h2>

Area of a trapezium= 1/2(sum of parallel sides)×height

Area of the trapezium= 1/2(5+3)×17

Area of the trapezium= 1/2(8)×17

Area of the trapezium=4×17= 68cm^2

Use z scores to compare the given values. Based on sample​ data, newborn males have weights with a mean of 3227.9 g and a standa
sasho [114]

Answer:

The weight that is more extreme is the male which is -2.62

Step-by-step explanation:

Consider the provided information.

Now use the z scores formula:

z=\frac{x-\mu}{\sigma}

Where μ is mean and σ is the standard deviation.

For newborn males have weights with a mean of 3227.9 g and a standard deviation of 659.9 g.

Substitute the respective values in the above formula.

z=\frac{1500-3227.9}{659.9}\approx-2.62

For Newborn females have weights with a mean of 3073.1 g and a standard deviation of 806.8 g.

Substitute the respective values in the above formula.

z=\frac{1500-3073.1}{806.8}\approx-1.95

So, the more extreme of these is the male which is -2.62

Please answer the question from the picture above
gregori [183]
If the denominators are not the same, then you have to use equivalent fractions which do have a common denominator . To do this, you need to find the least common multiple (LCM) of the two denominators. To add fractions with unlike denominators, rename the fractions with a common denominator. Then add and simplify.

https://www.coolmath4kids.com/math-help/fractions/adding-and-subtracting-fractions-different-denominators

For example:
1/2 + 1/3

We need to find something called the least common denominator (LCD)... It's really just the LCM of our denominators, 2 and 3.

The LCM of 2 and 3 is 6. So, our LCD 6.

We need to make this our new denominator...

Change the 1/2:

1 x 3 over 2 x 3 = 3/6

Change the 1/3:



1/2 + 1/3 = 3/6 + 2/6

Now we can do it!

(3+2)/6 = 5/6

What is the y-intercept of the quadratic function f(x) = (x – 6)(x – 2)? (0,–6) (0,12) (–8,0) (2,0)
rosijanka [135]
It would be the second choice or letter B - (0,12)

To get the y-intercept, set x as zero. Substitute then simplify. Negative six times negative two would equal to positive twelve.
Set: x = 0
Solution: f(x) = (0 - 6) (0 - 2)
                f(x) = -6 x -2
Answer: y = 12
