you could use to find 5 + 8.

Answer:
5 + 8 = 13 or

8 + 5 = 13

8 + 5 = 13

One number is 10 more than twice another. Their sum is 1. Find the numbers

12. In Europe, 88% of all households have a TV. 51% of all households have a TV and VCR. What is the probability that a household has a VCR given they have a TV?

Y=6cosx^2 (derivative)

7. Here is a system of equations:-x+6y=9 x+6y=-3 Would you rather use subtraction or addition to solve the system? Explain your reasoning. (Lesson 2-14)

Write the number 0.0049 in scientific notation.

**Answer: **

**Step-by-step explanation:**

**Answer:**

**Step-by-step explanation:**

**Given :** A random sample of 10 subjects have weights with a standard deviation of 11.9407 kg

i.e.

Since we know that the value of variance is the square of standard deviation.

i.e.

Therefore, to find the value of variance, we need to find the square of the given standard deviation.

i.e.

**Thus, the variance of their weights =**

B)24

C)30

D)36

**Answer:**

24 years.

B is correct option.

**Step-by-step explanation:**

Let Sunita's current age is x and that of Mark's is y.

Hence, we have

**Now, in 12 years the ratio will be 5 to 6. Thus, we have**

**Cross multiplying, we get**

**Plunging, the value of x from equation (1)**

**Therefore, Mark's current age is 24 years.**

Mark's current age is 24

**Answer:**

B

**Step-by-step explanation:**

There are two correct answers to the question :A and D. Therefore you have a 50% of getting the correct answer.

Hope the helps :)

**Answer:**

**Range : [-6, ∞)**

**Step-by-step explanation:**

Domain of any function on a graph is represented by the x-values (input values).

Similarly, Range of function is represented by the y-values or output values of the function on a graph.

Therefore, domain of the given absolute function will be (-∞, ∞) Or set of all real numbers.

**Range of the function → [-6, ∞) Or {y | y ≥ -6}**

**Answer:**

14/19

**Step-by-step explanation:**

Note that there are two " - " signs here. Thus, the end result will be " + "

We move from left to right, obtaining first 10/19 divided by (5/7):

10

----- ÷ (5/7)

19

To divide by (5/7), invert (5/7) and then multiply. We get:

10 7 2(7)

----- * ----- = ------- = **14/19**

19 5 19

**Answer:**

6.8

**Step-by-step explanation:**

27 / 4 = 6.75, which rounded to the nearest tenth, is 6.8.
