The brain volumes ?( cm cubed cm3?) of 20 brains have a mean of 1083.9 1083.9 cm cubed cm3 and a standard deviation of 122.2 122

Colt1911 [192]

Answer:

Range: (844.9,1333.7)

A brain volume of 1348.3 cm cubed can be considered significantly high.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 1083.9 cm cubed

Standard Deviation, σ = 122.2 cm cubed

Range rule thumb:

This rule state that the the range of data is four times the standard deviation of the data.

$\text{Range} = 4\times \sigma = 4\times 122.2 = 488.8$

Upper Limit:

$\mu + 2\sigma = 1089.3 + 2(122.2) = 1333.7$

Lower limit:

$\mu - 2\sigma = 1089.3 - 2(122.2) = 844.9$

Since, 1348.3 does not lie in the range (844.9,1333.7), a brain volume of 1348.3 cm cubed can be considered significantly high.

Alyssa said that 6/8 and 9/12 are not equivalent because there is no whole number you can multiply both part of 6/8 by to get 9/

BigorU [14]

Solution: Alyssa is incorrect.

In fact $\frac{6}{8}=\frac{9}{12}$ .

If we cross-multiply the above equation, we have:

$6 \times 12 = 9 \times 8$

$72 = 72$

Therefore, they are equal.

Also, if we reduce the given fractions, we have:

$\frac{6}{8} =\frac{3}{4}$

And

$\frac{9}{12}=\frac{3}{4}$

Since both the fractions reduced to $\frac{3}{4}$ , therefore fractions are equivalent.

Which polynomial is a difference of squares?

Svetllana [295]

<u>Answer</u>

D.25x2 – 36

<u>Explanation</u>

A. x² – 16x + 64

product = 64

sum = -16

factors: -8 and -8

x² – 16x + 64 = x² - 8x - 8x + 64

= x(x - 8) - 8(x - 8)

= (x - 8)(x-8) = (x-8)² ⇒ Not a difference of squares

B.x² + 4 = (x² + 2²) ⇒ Not a difference of squares

C.9x² – x – 36

product = - 324

sum = -1

Factors: none

9x² – x – 36 ⇒ Has no perfect roots.

D.25x² – 36

25x² – 36 = (5x)² - 6² ⇒ This is the difference of squares.
