The ratio is 42:36. Than to simplify its 7:6 because both are divisible by 6 and 42 divided by 6 is 7. 36 divided by 6 is 6.

The penguins currently living on an island are of two types, Chinstrap penguins and Gentoo penguins. The range of the heights of

velikii [3]

Answer:

The answer is "Option A"

Step-by-step explanation:

Using the range difference to calculate the maximum and minimum value.

The range of the chinstrap penguins are:

$R(c) = Max(c) - Min(c) = 13.2$

The range of the Gentoo penguins are:

$R(g) = Max(g) - Min(g) = 15.4$

For point A:

$Max(c) = x\\\\Max(g) = x + 5.8\\\\R(c) = x - Min(c) = 13.2 \to x = 13.2 + Min(c)\\\\R(g) = x + 5.8 - Min(g) = 15.4 \to x = 9.6 + Min(g)$

equate both of them

$13.2 + Min(c) = 9.6 + Min(g)Min(g) - Min(c) = 3.6$

It indicates that Min(c) surpasses Min(g), whereas Max(g) exceeds Max (c).

Therefore, the Max is picked for g for all penguins and the minimum is picked for c.

Range of all penguins $= Max(g) - Min(c) = x + 5.8 - x + 13.2 = 19$

Therefore, it will be determined as the option.

For point B:

In estimating the range the median height cannot help.

For point C:

In order to calculate the variety, the connection between both the mean height cannot be sued.

Part 1: Create your own quadratic equation that cannot be solved by factoring, but can be solved using the quadratic formula. Id

eimsori [14]

when you use all prime, non-one numbers for b and c, it cannot be factored most of the time

example
1x^2+7x+5
a=1
b=7
c=5
x= $\frac{-b+/- \sqrt{b^2-4ac} }{2a}$
x= $\frac{-7+/- \sqrt{7^2-4(1)(5)} }{2(1)}$
x= $\frac{-7+/- \sqrt{49-20} }{2}$
x= $\frac{-7+/- \sqrt{29} }{2}$
x= $\frac{-7+ \sqrt{29} }{2}$ or $\frac{-7- \sqrt{29} }{2}$

Find 15 * 15 * 15 * 500 how does this compare to finding 45 x 500

andrew11 [14]

15 * 15 * 15 * 500 = 1,687,500. it's different from finding 45 * 500 because
15 * 15* 15 * 500 is the same as writing it as 15^3 * 500. This meaning you multiply the number 15 by itself 3 times, not add it 3 times, which is what
45 * 500 was showing. I hope this helped.
