Answer:

12x - 30 = 3(4x - 10)

In my guess,this is right

As the questions 12 and 30 are numbers and for factorization in it 3 is common also 2 is but I select 3 cause it is easier

An 60 ounce bottle of grape juice contains 33 ounces of water a 50 ounce bottle of cranberry juice has 30 ounces of water which

sp2606 [1]

Answer:

Bottle containing cranberry juice has a greater percent of water.

Step-by-step explanation:

A 60 ounce bottle of grape juice contains 33 ounces of water.

So the percentage of water in the bottle = $\frac{\text{Amount of water}}{\text{(Amount of water + juice)}}\times 100$

= $\frac{33}{60}\times 100$

= 55%

Similarly 50 ounces bottle of cranberry juice contains 30 ounces of water.

So the percentage of water in the bottle = $\frac{\text{Amount of water}}{\text{(Amount of water + juice)}}\times 100$

= $\frac{30}{50}\times 100$

= 60%

Therefore, bottle containing cranberry juice has a greater percent of water.

A manufacturer produces widgets that are packaged in boxes of 100. The probability of a widget being defective is 0.021. Find th

gavmur [86]

Answer:

$\=x=2.1$

$\sigma=2.03$

Step-by-step explanation:

From the question we are told that:

Sample size $n=100$

Probability of a defective widget $P=0.021$

Generally the equation for binomial trial is mathematically given by

$q=1-p$

$q=1-0.021$

$q=0.979$

Since X is binomial random variable with functions of n and p,The equation of mean \=x

$\=x=E(x)$

Where

$E(x=n*p)$

$\=x=100*0.021$

$\=x=2.1$

Generally the equation for variance \sigma is mathematically given by

$\sigma=\sqrt{nqp}$

$\sigma=\sqrt{200*0.021*0.979}$

$\sigma=2.03$
