What is the value of x

Answer:

Answer: (√3)/2

Step-by-step explanation:

[tex] \sin(35 \degree) \cos(25\degree) + \cos(35\degree) \sin(25\degree) \\ [/tex]

from trigonometry identities:

[tex] \sin(a + b) = \sin(a) \cos(b) + \cos(a) \sin(b) \\ [/tex]

a » 35°

b » 25°

Therefore;

[tex] = \sin(35\degree + 25\degree) \\ = \sin(60\degree) \\ \\ = \frac{ \sqrt{3} }{2} [/tex]

Answer:  Choice C.

The difference between our sample mean and our hypothesized mean was statistically significant.

=========================================================

Explanation:

The null hypothesis is always set up in a way to state the following: "The mean mu is equal to some value"

The mu is a greek letter often used as the population mean symbol. The actual symbol itself looks like this [tex]\mu[/tex]

When we reject the null, we reject the idea that the mu is whatever stated value we said in the null. So we must go with the alternative hypothesis.

The sample mean we computed (xbar) is different enough from the mu value that we're able to make such a rejection. We consider this statistically significant, which is another way of saying that such a difference is not simply due to random chance.

Answer:

In general, to round to a certain place value, look at the digit to the right of that place value and make a decision. Example: 5.1837 to the nearest hundredth would be 5.18 (round down since 3<5 ), but to the nearest thousandth, it is 5.184 (round up because 7≥5 ).

Answer:

  -1/2048

Step-by-step explanation:

The Order of Operations tells you to evaluate each of the exponential expressions first. Then you do the division.

  = (1/32) / (-64)

  = -1/(32·64) = -1/2048

__

You can also rewrite the expression in terms of powers of 2.

  2^-5/-4^3 = -1/((2^5)(2^2)^3) = -1/(2^5×2^6) = -1/2^11

  = -1/2048

_____

The applicable rules of exponents are ...

  a^-b = 1/a^b

  (a^b)^c = a^(bc)

  (a^b)(a^c) = a^(b+c)

  4 = 2^2

  2^5 = 32

  4^3 = 64

Answer:

-4%   -1/25

Step-by-step explanation:

To convert a decimal to a percentage, multiply it by 100.

-0.04 * 100 = -4

To convert a decimal to a fraction, put the decimal as a fraction over 1 and multiply until the numerator (top number) is a whole number and then simplify.

[tex]\frac{-0.04}{1}[/tex] x [tex]\frac{100}{100}[/tex] = [tex]\frac{-4}{100}[/tex]

-4/100 simplified = -1/25 (because 4 goes into 100 25 times)

Answer:

Step-by-step explanation:

Answer: Interval notation: (−∞, 3) ( − ∞, 3) Any real number less than 3 in the shaded region on the number line will satisfy at least one of the two given inequalities. Example 4: Graph and give the interval notation equivalent: x<3 or x≥−1. x < 3 or x ≥ − 1. .

The statement in the mathematical form will be x ≤ 3. Then the inequality in the interval notation will be [3, ∞).

Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.

The act of converting a specified statement into an expression or equation is known as a sentence-to-equation transformation.

x is less than or equal to 3.

Convert the statement into a mathematical inequality. Then we have

x ≤ 3

The statement "x is less than or equal to 3" in the mathematical form will be x ≤ 3.

Thus, the inequality in the interval notation will be [3, ∞).

Step-by-step explanation:

Sara used 0.36 pounds of slug slime to make soup for her six friends.

Multiplication is an operation that represents the basic idea of repeated addition of the same number. The numbers that are multiplied are called the factors and the result that is obtained after the multiplication of two or more numbers is known as the product of those numbers.

Given that, Sara was making slug slime soup for her six friends.

She needed 0.06 pounds of slug slime for each serving of soup.

So, total slug slime needed is

6×0.06

= 0.36

Therefore, the total slug slime needed for the soup is 0.36 pounds.

Answer:

  83 m

Step-by-step explanation:

The attached diagram shows the lengths of the midlines to be 3.16 and 5.10 units on the coordinate plane. The sum of these is (3.16 +5.10) = 8.26 coordinate plane units. Since each unit on the coordinate plane represents 10 m, the total path length is about ...

  8.26(10 m) = 82.6 m ≈ 83 m

_____

The distance formula will tell you the distances are ...

  AC = √(3² +1²) = √10

  BD = √(5² +1²) = √26

The total path length is about (10 m)(√10 +√26) ≈ 82.61230 m ≈ 83 m.

Answer:

Step-by-step explanation:

Given :

x-y = 3                                equation(i)

2x + 3y = 4                           equation(ii)

Now,

x - y = 3

x = 3 + y

substitute the value of x in equation (ii)

2x + 3y = 4

2(3 + y) + 3y = 4

6 + 2y + 3y = 4

6 + 5y = 4

y = -2/5

The number of non-medicine that can be sent is approximately 14 boxes.

From the given statement we can form the following equation:

let the worth of a boxes of medicine = x

3x + 7(300) = 9,000

solve for x:

3x + 7(300) = 9,000

3x + 2,100 = 9,000

3x = 9,000 - 2,100

3x = 6,900

[tex]x = \frac{6,900}{3} = 2,300[/tex]

A box of medicine worth $2,300

If only 2 boxes of medicine will be sent, then the number of boxes of non-medicine is calculated as;

let the worth of all the boxes of non-medicine = y

2(2,300) + y = 9,000

4600 + y = 9,000

y = 9,000 - 4600

y = 4,400

Now we solve for the number of boxes of non-medicine as follows:

n(300) = 4,400

[tex]n= \frac{4400}{300} = 14.67 \approx 14 \ boxes \ of \ non-medicine \ can \ be \ sent[/tex]

Thus, the number of non-medicine that can be sent is approximately 14 boxes.
