Answer:
The last one.
Step-by-step explanation:
You can begin by dividing by - 2
-2*abs(x) =-6
-2*abs(x)/-2 = - 6/-2
abs(x) = 3
So x can be -3 or 3. Both are solutions
That's the last one.

The measure of an angle is 78.7°. What is the measure of its complementary angle
Answer:
Step-by-step explanation:
in complementary angle, the sum of two angle is always 90 degree.
let another angle be x
x+78.7=90
x=90-78.7
x=11.3
therefore anothere angle is 11.3 degree.

The probability of the complement of event A P(Ac), which is the event of a place to not be a city, is 4/7. Option C is correct.
How to find the probability of an event?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event.
A place from this table is chosen at random. Let event A= the place is a city.
The total number of places are 7 given in the table.There are total three places which are city. Thus, the probability of a country to be a city is,
[tex]P(A)=\dfrac{3}{7}[/tex]
Now, for its complement, the probability of a place not be a city is,
[tex]P(A^c)=1-\dfrac{3}{7}\\P(A^c)=\dfrac{7-3}{7}\\P(A^c)=\dfrac{4}{7}[/tex]
Thus, the probability of the complement of event A P(Ac), which is the event of a place to not be a city, is 4/7. Option C is correct.

Tony has 75 dollars to spend on a game controller that costs $35 and used video games
costing 8 dollars each. How many video games can he buy?
Answer:5 I think
Step-by-step explanation:
75-35=40 40 divided by 8 is 5
Answer:
The answer is 5=x (he is able to buy 5 videogames)
Step-by-step explanation:
First, you need to put this into an equation format with a variable (x) for the videogames. Here is what the equation should look like: 75 = 35 + 8x
75 being the total amount of money he has to spend, 35 being what he had to spend or knows he will spend on the controller, and the 8 is for each videogame. We put an 'x' behind the 8 to signal that we don't know how many games he can buy. So, then we need to solve the equation.
75=35+8x
-35 on both sides
So, 40=8x, then you divide by 8 to get x by itself
5=x
The 'x' in this equation is how many videogames he is able to buy. The way you could check your work is if you plugged 5 back into x. What I mean is this: 35+8(5) needs to equal 75, and it does, so you're good!

What are sine and cosine rules?The law of sine or the sine law states that the ratio of the side length of a triangle to the sine of the opposite angle, which is the same for all three sides.
The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.
Given that, a village R is 10 km from a point P on a bearing 25° from P. Another village A is 6 km from P on a bearing 162°.
We need to calculate, the distance R from A and the bearing of R from A
We will use the Cosine Rule to determine the distance of R from A (p);
From Cosine Rule;
b² = a² + c²– 2ac Cos B
p² = a² + r² – 2ar Cos P
a= 10 km
Cos P = Cos 137
r = 6 km
p = ?
p² = a² + r² – 2ar Cos P
p² = 10² + 6² - 2 (10) (6) Cos 1370
p² = 100 + 36 – 120 (- 0.7314)
p² = 136 + 87.76
p² = 223.76
p = 14.95 = 15 km (approximated to the nearest km)
To find the bearing of the R from A,
we will apply Sine Rule;
From Sine Rule;
15Sin Ø = 10Sin 137 = 6.82
Sin Ø = 6.82/15 = 0.4547
Ø = ArcSin 0.4547 = 27°
Therefore, the bearing of R from A will be
∠ PRA = 180 – 137 – 27 = 160
The alternating angle to 25° at R is 65°
Then, the bearing of R from A = 270 -65-16 = 189°
Hence, the distance R from A and the bearing of R from A 15 km and 189° respectively.

Roll the number cube to find the observed frequency. Which statements are true? Check all that apply
Answer:
(a) and (c)
Step-by-step explanation:
Given
See attachment for complete question
Required
Select all true statements
First, calculate the total observed frequency;
[tex]Total = 11 + 16 + 14 + 20 + 12 + 17[/tex]
[tex]Total = 90[/tex]
(a): Relative frequency of 4 is 2/9
Relative frequency is calculated by:
[tex]RF= \frac{Observed\ Frequency}{Total}[/tex]
For roll 4
[tex]Observed\ frequency = 20[/tex]
So, the relative frequency is:
[tex]RF = \frac{20}{90}[/tex]
Simplify
[tex]RF = \frac{2}{9}[/tex]
(a) is true
(b): Experimental probability of 3 greater than its theoretical probability
The experimental probability is its relative frequency;
For roll 3
[tex]Observed\ frequency = 14[/tex]
The experimental probability is:
[tex]Pr = \frac{14}{90}[/tex]
Simplify
[tex]Pr = \frac{7}{45} = 0.156[/tex]
To calculate the theoretical probability, w have:
[tex]S = \{1,2,3,4,5,6\}[/tex] ---- sample space
[tex]n(S)= 6[/tex]
[tex]n(3) = 1[/tex] --- number of times 3 occur
The theoretical probability is:
[tex]Pr = \frac{1}{6} = 0.167[/tex]
The theoretical probability is [tex]greater\ than\ the[/tex] experimental probability.
(b) is false
(c): Experimental probability of 2 greater than its theoretical probability
Using the explanations in (b), we have:
For roll 2
[tex]Observed\ frequency = 16[/tex]
The experimental probability is:
[tex]Pr = \frac{16}{90}[/tex]
Simplify
[tex]Pr = \frac{8}{45} = 0.178[/tex]
To calculate the theoretical probability, we have:
[tex]n(S)= 6[/tex]
[tex]n(2) = 1[/tex]
The theoretical probability is:
[tex]Pr = \frac{1}{6} = 0.167[/tex]
The experimental probability is [tex]greater\ than\ the[/tex] theoretical probability.
(c) is true
(d): Relative frequency of 5 is 2/13
For roll 5
[tex]Observed\ frequency = 12[/tex]
The relative frequency is:
[tex]RF = \frac{12}{90}[/tex]
Simplify
[tex]RF = \frac{2}{15}[/tex]
(d) is true

You are road tripping down the California coast and you notice you need to fill up your gas tank. In CA, sales tax is 2.25%. You spend $56.00 to fill up your tank. How much are you paying in sales tax?
Answer:
$1.26
Step-by-step explanation:
So you just have to find 2.25% of 56.
To find a certain percentage of something, you multiply it. Let's write out a sentence explaining what you need to do. You have to find:
2.25% of 56
Whenever you've got a sentence like this, all you've got to do is change the word "of" to a multiplication symbol. And now you've got an expression:
2.25% × 56
Let's convert the percentage to a decimal. To do this, you simply remove the percent symbol, then move the decimal point 2 places to the left.
2.25% = 0.0225
And now you have:
0.0225 × 56
Then you just do the math! I am assuming you already know how to do decimal multiplication so I'm not going to explain the process here.
But once you multiply 0.0225 × 56, you get an answer: 1.26
