Answer: 1440
Explanation: when you split it into two shapes (I split it where the split is splitting the eight up) you find the volume of them both. Top shape= 4x4x10=80 bottom shape= 8x8x10=640.
640+80= 720
You will then need to multiply by two (or add 720+720) to get the answer 1440

Alex_Xolod [135]

Answer:

45 pieces.

Step-by-step explanation:

First, if the ratio is 5 : 4, then is you multiply 4 x 5 to get 20, you need to multiply 5 x 5 to get 25.

Second, 20 + 25 = 45 which is the total amount of puzzle pieces.

Hope this helps!

Let x be a discrete random variable that possesses a binomial distribution with n=5 and p=0.87. What are the mean and standard d

Nookie1986 [14]

Answer:

$Mean = 4.35$

$SD = 0.5655$

Step-by-step explanation:

Given

$n = 5$

$p = 0.87$

Solving (a): Mean

$Mean = np$

$Mean = 5 * 0.87$

$Mean = 4.35$

Solving (b): Standard Deviation (SD)

$SD = np(1 - p)$

$SD = 5 * 0.87(1 - 0.87)$

$SD = 5 * 0.87 * 0.13$

$SD = 0.5655$

In ΔXYZ, XY = 6.32, YZ = 5.83, and XZ = 11.05. m∠Y = º.

Dominik [7]

Answer: 130.8 degrees

Explanation:

The problem can be solved by using the cosine theorem:

$a^2 = b^2 + c^2 - 2bc cos \alpha$ (1)

where

a,b,c are the lengths of the three sides of the triangle

$\alpha$ is the angle between b and c

In this problem, we can identify a,b,c, with:

a = XZ = 11.05

b = XY = 6.32

c = YZ = 5.83

So, the angle $\alpha$ corresponds to the angle m∠Y. Re-arranging eq.(1), we find

$cos \alpha = \frac{b^2+c^2-a^2}{bc}=\frac{(6.32)^2+(5.83)^2-(11.05)^2}{2(5.83)(6.32)}=-0.654$

So, the angle is

$\alpha=cos^{-1}(-0.654)=130.8^{\circ}$

Question 1 of 16

irga5000 [103]

None of the alternatives are correct. The domain's lower bound is 6, however it contains 6, therefore a bracket is required rather than a parenthesis. [6 (infinity)] Because infinity is not included, a bracket for infinity is invalid. The range is from 0 to infinity. assuming you meant 1/sqr (x-6). However, none of the options are right if you meant 1/(sqr(x) - 6).

or did you mean 1/sqrx - 6? However, none of them are correct.
