Binomial has two terms.
Here A and B contains two terms.
C and D polynomials.
Now, In A. 7x^3y-13x^4 Here the highest degree is 4, So exclude option A because it is given that the binomial degree is 3.

We have now option B -2xy^2 - 19. Here degree of binomial is 3.

Answer: Option B

Help! 6th grade fractions math!!

Each "x" on the number line seems to represent a tree that sap has been collected from. That's 15 trees. Furthermore, you know that the total amount of sap is 8 gallons, because it's stated in the question.
To get the amount of sap that would be collected from each tree if it had been distributed equally (also known as the <em>average</em> amount of sap collected from each tree), just do exactly that.
Mathematically, this means you would divide the 8 gallons by 15 trees, or 8 ÷ 15. The total amount of sap collected is equivalent to an average of eight fifteenths of a gallon per tree.
Hope that helps c:

A machine has four components, A, B, C, and D, set up in such a manner that all four parts must work for the machine to work pro

olchik [2.2K]

Answer:

0.756

Step-by-step explanation:

It is given that a machine has four components, A, B, C, and D.

$P(A)=P(B)=0.93, P(C)=0.95,P(D)=0.92$

If these components set up in such a manner that all four parts must work for the machine to work properly.

We need to find the probability that the machine works properly. It means we have to find the value of $P(A\cap B\cap C\cap D)$ .

If two events X and Y are independent, then

$P(X\cap Y)=P(X)\times P(Y)$

Assume the probability of one part working does not depend on the functionality of any of the other parts.

$P(A\cap B\cap C\cap D)=P(A)\times P(B)\times P(C)\times P(D)$

Substitute the given values.

$P(A\cap B\cap C\cap D)=0.93\times 0.93\times 0.95\times 0.92$

$P(A\cap B\cap C\cap D)=0.7559226$

$P(A\cap B\cap C\cap D)\approx 0.756$

Therefore, the probability that the machine works properly is 0.756.

7 out of 28 is what percent?

jeka57 [31]

Here's what I did and I checked it So it is correct!!

$\frac{7}{28} = \frac{1}{4}$

$\frac{1}{4} = 0.25$

25% is your answer.

$28 \times 25\% = 7$

Answer:

$0.50

Step-by-step explanation:

Since there are 24 loafs, and in total they all cost $12, you would divide $12 by 24 loafs, which equals $0.50 for each loaf.
