Answer:

c. (x^2+1)(x^2+a)-a = x^2(x^2+a+1)

Step-by-step explanation:

You can use FOIL or the distributive property to expand the product of binomials, Then collect terms and factor out the common factor.

(x^2+1)(x^2+a)-a

= x^2(x^2 +a) +1(x^2 +a) -a

= x^4 +ax^2 +x^2 +a -a

= x^4 +ax^2 +x^2

= x^2(x^2 +a +1) . . . . . matches choice C

Can anyone help me with this proportion ,please?? I'm having a really hard time trying to solve it

SVEN [57.7K]

Answer:

320 pound

Step-by-step explanation:

Ratio is decently easy after u understand the concept

So... This is what the question gave

Jupitar : earth

8 : 3

In other words, if u weigh 8 pound on Jupitar, u would weigh 3 pounds on earth

Therefore now they say on earth, the person weighs 120 pound, so let's just put in this value

Jupitar : earth

8 : 3

? : 120

Now its called ratio bcuz the increase at the same pace

So now look at the earth part, u got to find out how did 3 become 120, so just divide them

120/3 = 40 , so 3 x 40 = 120

So if they multiplied the right ( earth) by 40, u do the exact same on the left ( Jupitar)

8 x 40 = 320

Thats your answer my friend

A baker knows that the daily demand for strawberry pies is a random variable that follows the normal distribution with a mean of

Elan Coil [88]

The demand that has an 8% probability of being exceeded is 38.1230 .

<h3>What is probability?</h3>

Probability is the aspect of mathematics that focus on the occurrence of a random event.

This is calculated below:

The normal random variable having the mean is been given as :

(Mu = 31.8)

The standard deviation is been given as ( sd = 4.5)

Then in making our calculation, we will need to make use of the formular below:

$\\Z= (X - Mu) / sd = (X - 31.8) / 4.5$

But we know that going with the probability of 0.08

where k = 1.4051

P (Z > 1.4051)

k = 1.4051

we can have the expression for k as $[(X - 31.8) / 4.5]$

This can be simplified as:

X = 4.5 (1.4051) + 31.8 = 38.1230.

Therefore, the demand that has an 8% probability of being exceeded is 38.1230 .
