Table (2) is a probability distribution table.
What is probability?Probability is the possibility of happening an event.
Note the probability can never be negative, therefore, discard the tables with negative values.
Hence, table (1) and table (3) cannot be probability distribution tables.
Now, the sum of all probabilities in a probability distribution is always 1.
The sum of probabilities in the table (2) is:
0.6 + 0.05 + 0.05 +0.3
=1.0
And, the sum of probabilities in the table(4) is:
0.4 + 0.4 + 0.2 + 0.1
=1.1
Therefore, table (2) is a probability distribution table.

Answer:
6 11/15
Step-by-step explanation:
So the equation is 6 9/10 - 1/6, you gotta have similar denominators to have an easy subtraction process. So 9/10 - 1/6. Both numbers go into 60. 10×6 so that becomes the new denominator. Now your numerator, the 9 is times 6 because the 10 gets times by 6 so 9 times 6 = 54. You got your first fraction done and you put I back with the whole number so 6 54/60. So 1/6 10 times 6 equals 60 so now 1/60 times the 1 by 10 whatever you do to the bottom you do to the top 1 times 10 is 10 so we got out second fraction 10/60 so now it's 6 54/60 - 10/60, 54 - 10 = 44 so your answer is 6 44/60 but we can simplify so 44 ÷ 2 = 22 and you do it to the bottom 60 ÷ 2 = 30 now we got 22/30 we can divide by 2 again and we get 11/15. Put it back with the whole number and we get 6 11/15

Find an equation in point-slope form for the line having the slope m= - 4 and containing the point (4,5).
The equation in point-slope form is
(Use integers or fractions for any numbers in the equation.)
Step-by-step explanation:
The point-slope form of a line is (y - y₁) = m(x - x₁)
Since we know the slope (m) is -4
And the point ( x₁, y₁ ) is (4, 5)
Then we can just plug these into the equation above:
⇒ y - 5 = - 4 (x - 4)
I often use Desmos to check my answer. As seen below, the equation does pass through the point (4, 5).

Answer:
18°
Step-by-step explanation:
1. ∠A and ∠B are complementary angles, so they add up to 90°.
This means that 2x - 4 + 5x + 17 = 902. To find the measure of ∠A, we first have to solve for x.
3. (Solving)
Step 1: Simplify both sides of the equation.
[tex](2x+5x)+(-4+17)=90[/tex] [tex]7x+13 = 90[/tex]Step 2: Subtract 13 from both sides.
[tex]7x + 13 - 13 = 90 - 13[/tex] [tex]7x = 77[/tex]Step 3: Divide both sides by 7.
[tex]\frac{7x}{7} = \frac{77}{7}[/tex] [tex]x = 11[/tex]4. Now that we know x = 11, let's plug that value into (2x - 4) to find the measure of Angle A.
[tex]2(11)-4[/tex] [tex]22-4[/tex] [tex]18[/tex]Therefore, the measure of ∠A = 18°.
Answer:
m<A = 18
Step-by-step explanation:
Since <A and <B are complementary angles, that just means those 2 angles combined equal 90:
<A + <B = 90
2x - 4 + 5x + 17 = 90
7x + 13 = 90
7x = 90 - 13
7x = 77
x = 77/7
x = 11
m<A:
2x - 4
2(11) - 4

Answer:
Answer is in the pic
Step-by-step explanation:
A translation is just a movement of the figure so in this case you just add 3 to the x part of the coordinate.
so originally k (-2,5) m (-3,1) l (1,1)
add 3 to x so
k (1,5) m (0,1) l (4,1)
If 3-(x - 2) = 1/27, what is the value of x?
5
3
-1
-5
First, raise the denominator (27) to the power of 1:
3^-(x-2) = 1/27^1
Next, use the negative exponent rule that is represented by the equation of 1/b^n = b^-n and then move 27 to the numerator:
3^-(x-2) = 27^-1
Rearrange the term so that both equations have the same base:
3^-(x-2) = 3^-3
Now when noticing how this has been completed, it is noticed that since both of these equations have the same bases, the only thing left to do is have the exponents equal one another. For now, ignore the bases and focus only on the two sets of exponents -(x - 2) and (-3). Lets make a new equation with only the exponents:
-(x - 2) = -3
Next, add the distributive property on the left side of the equation to remove the - sign outside (Note: Double negatives equal positive)
-x + 2 = -3
Subtract 2 from both sides:
-x = -5
Finally, it is asking for positive x not negative, so divide both sides by -1:
x = 5
So, the answer is A which is 5.
If 3-(x - 2) = 1/27 then the value of x is a) 5.
To solve for x, we'll follow these steps:
1. Distribute:
Distribute the negative sign into the parentheses:
3 - (x - 2) = 1/27
3 - x + 2 = 1/27
Simplify:
5 - x = 1/27
2. Isolate x:
To solve for x, we need to get it alone on one side of the equation. Subtract 5 from both sides:
5 - x - 5 = 1/27 - 5
-x = -134/27
3. Multiply by -1:
To solve for x, multiply both sides by -1 to isolate x:
-1 * -x = -1 * -134/27
x = 134/27
4. Simplify:
[tex]x = \approx 4.9629[/tex]
Since none of the given options exactly match the calculated value, we can see that option a) 5 is the closest answer.
However, the precise solution is a fraction between 4 and 5, so none of the provided options is an exact match.
In summary, while none of the given options is an exact solution, the closest answer is a) 5.

Step-by-step explanation:
(i) 2x = 5
compare with ax+by+c = 0
→ 2x + 0.y - 5 = 0
» a = 2 ,b = 0 ,c = -5
(ii) y - 2 = 0
compare with ax + by + c = 0
→ 0.x + 1y -2 = 0
» a = 0 , b = 1 , c = -2
(iii) y/7 = 3
y = 3×7
y = 21
y - 21 = 0
compare with ax + by + c = 0

» a = 0 , b = 1 , c = -21
(iv). x = -14/13
13x = -14

Anna is counting the number of seeds in her fruit. Her watermelon has one less than three times the number of seeds as her apple. Her orange has 13 less than 5 times the number of seeds as her apple. Her watermelon has more seeds than her orange. Which inequality represents the number of seeds her apple could have?
Inequalities are used to represent unequal expressions
The inequality that represents the number of seeds her apple could have is [tex]\mathbf{A < 6}[/tex]
Represent the fruits with the first letter.
So, we have:
[tex]\mathbf{W =3A - 1}[/tex] --- watermelon is one less than three times apple
[tex]\mathbf{O =5A - 13}[/tex] --- orange is thirteen less than five times apple
[tex]\mathbf{W > O}[/tex] --- the seeds in watermelon exceeds orange
Substitute expressions for W and O in [tex]\mathbf{W > O}[/tex]
[tex]\mathbf{3A - 1 > 5A - 13}[/tex]
Collect like terms
[tex]\mathbf{13- 1 > 5A - 3A}[/tex]
[tex]\mathbf{12 > 2A}[/tex]
Divide both sides by 2
[tex]\mathbf{6 > A}[/tex]
Rewrite as:
[tex]\mathbf{A < 6}[/tex]
The inequality that represents the number of seeds her apple could have is [tex]\mathbf{A < 6}[/tex]
