2x² + 10 factorización
Answer:
2(x² + 5)
Step-by-step explanation:
To factor 2x² + 10, we can first factor out the greatest common factor of the terms, which is 2:
2x² + 10 = 2(x² + 5)
We can't factor anymore, so the answer is:
2(x² + 5)
Answer:
2(x² + 5)
Step-by-step explanation:
To factorise this, do the distributive property backwards. In other words:
2x² + 10
2x² ÷ 2 + 10 ÷ 2
x² + 5
2(x² + 5)
∴ 2(x² + 5) is the answer

prove that the sum of the squares of any two odd numbers is always even
Answer:
proof below
Step-by-step explanation:
Remember that a number is even if it is expressed so n = 2k. It is odd if it is in the form 2k + 1 (k is just an integer)
Let's say we have to odd numbers, 2a + 1, and 2b + 1. We are after the sum of their squares, so we have (2a + 1)^2 + (2b + 1)^2. Now let's expand this;
(2a + 1)^2 + (2b + 1)^2 = 4a^2 + 4a + 4b + 4b^2 + 4b + 2
= 2(2a^2 + 2a + 2b^2 + 2b + 1)
Now the sum in the parenthesis, 2a^2 + 2a + 2b^2 + 2b + 1, is just another integer, which we can pose as k. Remember that 2 times any random integer, either odd or even, is always even. Therefore the sum of the squares of any two odd numbers is always even.

The price on Monday = 0.75
The price on Friday = 1.50
We need to find the change in price from Monday to Friday. It can be calculated as follows;
Change = 0.75 - 1.50
Change = 0.75 cents
therefore, the required change in the price is equal to 0.75 cents.

A library contains 60,000 books. 14,000 are the subject of business. 22,000 are on healthcare and and 12,000 on psychology and law . What percentage of the library books is on computing . If computing books make up two thirds of the remainder
Answer:
The percentage of computing books is 13.33%.
Step-by-step explanation:
The library consist of books on different subjects:
S = {Business, Healthcare, Computing, Psychology, Law,...}
There are a total of N = 60,000 books in the library.
Business (B) = 14,000
Healthcare (H) = 22,000
Psychology and Law (P&L) = 12,000
Remaining = N - B - H - P&L
= 60000 - 14000 - 22000 - 12000
= 12000
It is provided that computing books make up two thirds of the remainder.
Compute the number of computing books as follows:
C = 12000 × (2/3) = 8000
Compute the percentage of computing books as follows:
[tex]C\% = \frac{8000}{60000}\times 100=13.33\%[/tex]
Thus, the percentage of computing books is 13.33%.

A and B will take the same 10-question examination. Each question will be answered correctly by A with probability .7, independently of her results on other questions. Each question will be answered correctly by B with probability .4, independently both of her results on the other questions and on the performance of A. (a) Find the expected number of questions that are answered correctly by both A and B. (b) Find the variance of the number of questions that are answered correctly by either A or B.
(a) The expected number of questions answered correctly by both A and B is 28.
(b) The variance of the number of questions answered correctly by either A or B is 4.5.
Let's define the following variables:
X = Number of questions answered correctly by A
Y = Number of questions answered correctly by B
(a) Expected number of questions answered correctly by both A and B:
We can use the formula for the expected value of the product of two independent random variables:
E(X × Y) = E(X) × E(Y)
The probability of A answering a question correctly is 0.7, and the probability of B answering a question correctly is 0.4.
Since the questions are independent, we can calculate the expected values for X and Y:
E(X) = 10 (number of questions) × 0.7 (probability of A answering correctly) = 7
E(Y) = 10 (number of questions) × 0.4 (probability of B answering correctly) = 4
Now, the expected number of questions answered correctly by both A and B is:
E(X× Y) = E(X) × E(Y)
= 7×4
= 28
(b) Variance of the number of questions answered correctly by either A or B:
Variance is calculated differently for independent events. Since A and B's performances are independent, we can use the following formula:
Var(X + Y) = Var(X) + Var(Y)
The variance of a binomial distribution with n trials and probability p of success is given by np(1-p).
For A and B:
Var(X) = 10× 0.7 × (1 - 0.7)
= 2.1
Var(Y) = 10 × 0.4× (1 - 0.4)
= 2.4
Now, the variance of the number of questions answered correctly by either A or B is:
Var(X + Y) = Var(X) + Var(Y)
= 2.1 + 2.4
= 4.5

If $11000 yields $1100 over 5 years, what is the interest rate?
Answer:
1.92449%
Step-by-step explanation:
Simple Interest Rate Formula: A = P(1 + r)ⁿ
Step 1: Define variables
Principle amount P = 11000
Total amount A = 11000 + 1100 = 12100
Years n = 5
Step 2: Substitute and Evaluate for r
12100 = 11000(1 + r)⁵
11/10 = (1 + r)⁵
1.01924 = 1 + r
r = 0.019245
Step 3: Convert to percentage
0.019245 × 100 = 1.92449%
