What is the density of a material, if 132 grams of the material occupies 3 cubic centimeters?

1 answer:

5 0

You need to divide here, so 132/3 = 44, so that means it's D, 44 g/cm3. Hope this helped! Brainliest is always appreciated.

How can you determine whether a given number makes an equation true?

EastWind [94]

Answer:

By plotting in the number in the equation (aka where all the x’s are variables are) and seeing if it works.

Step-by-step explanation:

For example, let’s use the problem:

3x + 4 = 16

if the given number is 4, we fill it in for x-

3 (4) + 4= 16

solve to see if true:

12 + 4 = 16

16 = 16

hence, the given number 4 makes the equation true!

hopes this helps, have a great day :)

Data collected over time on the utilization of a computer core (as a proportion of the total capacity) were found to possess a r

Marianna [84]

Answer:

The probability that the proportion of the core being used at any particular time will be less than 0.10 is 0.08146

Step-by-step explanation:

$\mu =\frac{\alpha }{\alpha +\beta } = \frac{1}{1 + \frac{\beta}{\alpha} }$ 1/3 0.33 = 33.33 %

The Probability of that the proportion of the core being used at any particular time will be less than 0.10 is given by

PDF = $\frac{x^{\alpha -1} (1-x)^{\beta -1} }{\int\limits^1_0 {u^{\alpha -1} (1-u)^{\beta -1}} \, du }$

where x = 0.1

α = 2 and β = 4

PDF = $\frac{0.0729 }{\int\limits^1_0 {u^{\alpha -1} (1-u)^{\beta -1}} \, du }$ = 1.458

CDF = $\frac{\int\limits^{0.1}_0 {t^{\alpha -1} (1-t)^{\beta -1}} \, du }{\int\limits^1_0 {u^{\alpha -1} (1-u)^{\beta -1}} \, du }$ = 0.08146

The probability that the proportion of the core being used at any particular time will be less than 0.10 = 0.08146.

Write a recursive formula for the explicit formula.

Setler79 [48]

Answer: A

Step-by-step explanation:

$A_n=9+(n-1)*(-4)\\\\A_1=9+(1-1)*(-1)=9+0=9\\\\A_{n-1}=9+((n-1)-1)*(-4)\\\\A_n-A_{n-1}=9+(n-1)*(-4)-(9+(n-2)*(-4))=-4n+4+4n-8=-4\\\\\boxed{A_n=A_{n-1}-4}\\\\\\Answer\ A$

Which of the following options have the same value as %25, percent of 64? Choose 2 answers:

Alexxx [7]

Answer:

B and C

Step-by-step explanation:

25% of 64 is 16. So find the two answers that are equivalent to 16.

A: 25*64 = 1600 $\neq$ 16

B: $\frac{25}{100}$ *64 = 16

C: 0.25 * 64 = 16

D: 64/ $\frac{25}{100}$ =256 $\neq$ 16

E: 25/ $\frac{64}{100}$ = 39.06 $\neq$ 16
