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°

x is less than or equal to 3. What is the interval notation
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, ∞).
What is inequality?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, ∞).

When you round a number, what should you do with
the digits to the right of the place to which you
are rounding?
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 ).

A Christian relief agency is sending two types of medical supply boxes overseas. The original plan is to send 3 boxes of medicines and 7 boxes of non-medicine supplies worth a total value of $9,000. Shortly before the supplies are shipped, the agency receiving the supplies communicates that they only need 2 boxes of medicines. If a box of non-medicine supplies is worth $300, how many boxes of non-medicine supplies can be sent if only 2 boxes of medicine are included in the shipment
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.

What is the value of the expression -11 + 24 + (-32)
Answer:
-19
Step-by-step explanation:
Just used the calculator, hope this helps
Answer:
-19
Step-by-step explanation:
You can split the equation into two steps:
1. - 11 + 24. You can also flip around the terms and get 24 - 11. 24 - 11 = 13 so - 11 + 24 = 13.
Next -
2. 13 + (-32). When you are adding a negative number, it is the same as subtracting the positive of that number, so we can turn the equation into 13 - 32. 13 - 32 = -19

A city planner designs a park that is a quadrilateral with vertices at J(-1, 1), K (3, 3), L (5, -1), and
M(-1,-1). There is an entrance to the park at the midpoint of each side of the park. A straight path
connects each entrance to the entrance on the opposite side. Assuming each unit of the coordinate plane
represents 10 meters, what is the total length of the paths to the nearest meter? Round your answer to
the nearest whole number.
The total length of the paths is approximately
meters.
9514 1404 393
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.

Step-by-step explanation:
The distance formula is used for this purpose.
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-5-(-3))² +(1 -8)²) = √((-2)² +(-7)²) = √(4+49) = √53

Let's suppose we conduct a hypothesis test about the mean value of something, and determine that we should reject the null hypothesis. What does that mean?
a. Our hypothesized mean has been proven incorrect
b. The difference between our sample mean and our hypothesized mean was most likely due to random chance.
c. The difference between our sample mean and our hypothesized mean was statistically significant.
d. The difference between our sample mean and our hypothesized mean was not statistically significant.
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.

Step-by-step explanation:
Sara used 0.36 pounds of slug slime to make soup for her six friends.
What is multiplication?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

Write each decimal as a percent and a fraction -0.04
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)

= -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
