9/12 so 12 triés because 9*3=27 so you then have to multiply 4*3*12

Graph an inequality on a number line: 15>m

barxatty [35]

When the sign is ≤ or ≥ ("less/greater than <u>or equal to</u>"), the dot if filled in.

When the sign is < or >, the dot is not filled in/open circle.

15 > m

[15 is greater than m, or m is less than 15]

Since m is less than 15, the arrow is going to the left (the numbers to the left are less than 15)

NarStor, a computer disk drive manufacturer, claims that the median time until failure for their hard drives is more than 14,400

Ne4ueva [31]

Answer:

The test statistics is $t = -1.727$

Step-by-step explanation:

From the question we are told that

The data given is

330 620 1870 2410 4620 6396 7822 81028309 12882 14419 16092 18384 20916 23812 25814

The population mean is $\mu = 14400$

The sample size is n = 16

The null hypothesis is $\mu \le 14400$

The alternative hypothesis is $H_a : \mu > 14400$

The sample mean is mathematically evaluated as

$\= x = \frac{\sum x_i}{n}$

So

$\= x = \frac{330+ 620+ 1870 +2410+ 4620+ 6396+ 7822+ 8102+8309+ 12882+ 14419+ 16092+ 18384 +20916+ 23812+ 25814 }{16}$

=> $\= x = 10799.9$

The standard deviation is mathematically represented as

$\sigma =\sqrt{\frac{ \sum (x_i - \=x)^2}{n}}$

So

$\sigma =\sqrt{\frac{(330- 10799.9)^2 + (620- 10799.9)^2+ (1870- 10799.9)^2 +(2410- 10799.9)^2 + (4620- 10799.9)^2 +(6396- 10799.9)^2 +(7822- 10799.9)^2 }{16}} \ ..$

$..\sqrt{ \frac{(8102 - 10799.9)^2 +(8309 - 10799.9)^2 + (12882 - 10799.9)^2 + (14419 - 10799.9)^2 + (16092 - 10799.9)^2 + (18384 - 10799.9)^2 +(20916 - 10799.9)^2 }{16}} \ ...$

$\ ... \sqrt{\frac{(23812 - 10799.9)^2 +(25814 - 10799.9)^2 }{16}}$

=> $\sigma = 8340$

Generally the test statistic is mathematically represented as

$t = \frac{10799.9- 14400}{ \frac{8340}{\sqrt{16} } }$

$t = -1.727$

From the z-table the p-value is

$p-value = P(Z > t) = P(Z > -1.727) = 0.95792$

From the values obtained we see that

$p-value > \alpha$ so we fail to reject the null hypothesis

Which implies that the claim of the NarStor is wrong

What are the measurements of the little 2 small cube things on each side, better yet what's the surface area? Thank you

Arisa [49]

<u>Answer:</u>

166 units²

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

<u>We know that:</u>

W = 7
L = 5
H = 4

<u>Surface area is the area of the faces of the cuboid.</u>

<u>Work:</u>

=> 2(7 x 4) + 2(5 x 4) + 2(5 x 7)
=> 2(28) + 2(20) + 2(35)
=> 56 + 40 + 70
=> 166 units²

Hence, <u>Option C is correct.</u>

Hoped this helped.

Can someone please help?!!!

Nuetrik [128]

The perimeter of a rectangle is P=2l+2w where l is the length and w is the width.

Plug in values of l and w in:

P=2(x+8)+2(x-1)

P=2x+16+2x-2

P=4x+14

So the perimeter of the rectangle is 4x+14 units

Hope this helped!
