Cube is 27 cubic centimeters what is the area of each face

jarptica [38.1K]

Volume of a cube is side^3
therefor
v=27
27=side^3
what^3=27?
factor 27
27=3 times 3 times 3=3^3
27=side^3
3^3=side^3
cube roo bth sides
3=side

3 cm is on side
area=side^2
area=3^2
area=9 cm^2

Which is the graph of the linear inequality y < 3x + 1?

mestny [16]

Start at +1 on the x axis and then use 3/1 for rise over run. So you will start at +1 and then from that point rise 3 run 1

Hi,

The equation: (3^6)^2 x (3^0)

Multiply:

=(729^2)(3^0)

=531441 (3^0)

Simplify:

=(531441) (1)

Multiply again:

=531441 or D. (3^12)

Have a great day!

A sample of 900 computer chips revealed that 75% of the chips do not fail in the first 1000 hours of their use. The company's pr

Answer:

No the evidence is not sufficient

Step-by-step explanation:

From the question we are told that

The sample size is $n = 900$

The sample proportion is $\r p = 0.75$

The population proportion is $p = 0.72$

The Null hypothesis is

$H_o : p = 0.72$

The Alternative hypothesis is

$H_a : p > 0.72$

The level of significance is given as $\alpha = 0.05$

The critical value for the level of significance is $t_{\alpha } = 1.645$

Now the test statistic is mathematically evaluated as

$t = \frac{\r p - p }{ \sqrt{\frac{p(1-p)}{\sqrt{n} } } }$

substituting values

$t = \frac{ 0.75 - 0.72 }{ \sqrt{\frac{0.72 (1-0.72)}{\sqrt{900} } } }$

$t = 0.366$

Since the critical value is greater than the test statistics then the Null hypothesis is rejected which there is no sufficient evidence to support the claim
