Answer:
0.6
Step-by-step explanation:
A probability is the likelihood of an event occurring. A probability function is a function in which at any point, its probability value can be estimated. The integral of the probability function is always ≤ 1
To find the probability that x = 2 or 3, we simply add their respective individual probabilities, therefore:
P(X = 2 or 3) = P(X = 2) + P(X = 3) = P(2) + P(3) = 0.5 + 0.1 = 0.6.
P(X = 2 or 3) = 6

A paintball court charges an initial entrance fee plus a
fixed price per ball.
P represents the total price (in dollars) as a function of
the number of balls used n.
P=0.80n + 5.50
What is the price for 10 balls, not including the
entrance fee?
$....
Answer:
$8
Step-by-step explanation:
Firstly, Let us identify the variables in the functions.
The function states that for every n ball, the price is $0.80. Plus the $5.50.
Now that we know what the function stands for, we can substitute 10 into n, and remove the entrance fee of $5.50.
P=0.80n
This gives us $8, which means the price for 10 balls not including the entrance fee is $8.
Here is a rule to make a list of numbers: Each number is 4 less than 3 times the previous number. Start with 10, build a sequence of 5 numbers.
Answer:
10,26,74,218,650
Explanation:
Each number is 4 less then 3 times than previous number.
The list of number is bounded by a set of rules that guide the creation of the set of numbers. The first 5 terms are: 10, 26, 74, 218, 650
Represent the number of terms with n.
So, the nth term is: [tex]T_n[/tex]
The start of the build is 10 means:
[tex]T_1 = 10[/tex]
The rule to generate the next terms is:
[tex]T_{n+1} = 3 \times T_n - 4[/tex] ---- i.e. 4 less than 3 times the previous term
So, the next terms till the 5th are:
[tex]T_{2} = 3 \times 10 - 4 = 26[/tex]
[tex]T_{3} = 3 \times 26- 4 = 74[/tex]
[tex]T_{4} = 3 \times 74- 4 = 218[/tex]
[tex]T_{5} = 3 \times 218- 4 = 650[/tex]
So, the first 5 terms are: 10, 26, 74, 218, 650

Answer:
[tex]\frac{1}{2}(4x+6)+3x=7x+9[/tex]
[tex]\frac{1}{2}(4x+8)+3x=7x+9[/tex]
Step-by-step explanation:
By putting the numbers in the given equation,
[tex]\frac{1}{2}(4x+6)+3x=7x+9[/tex]
2x + 3 + 3x = 7x + 9
5x + 3 = 7x + 9
(5x + 3) - 7x = (7x + 9) - 7x
(5x - 7x) + 3 = 9
-2x + 3 = 9
(-2x + 3) - 3 = 9 - 3
-2x = 6
[tex]-\frac{2x}{2}=\frac{6}{2}[/tex]
-x = 3
x = -3
Therefore, our equation is correct which has a negative result.
In place of 6 if we use 8, value of x will be negative again.

Answer:
option 2.
Step-by-step explanation:
You use the y-intercept form: y=mx+b
mx=slope, and b=y-intercept.
Looking at this graph, you can see that the slope is -2/3 (rise over run), and the line is negative, so the slope becomes negative.
So now, we can see the only option having the slop -2/3x is option 2.

A boy weighing blank kilograms is riding a skateboard. He’s moving at 2 meters/second and has 40 joules of kinetic energy. He doubles his speed when he sees his friends ahead of him. His kinetic energy at the faster speed is blank joules.
Answer:
His kinetic energy at the faster speed is 160 J
Step-by-step explanation:
Here in this question, we are interested in calculating the kinetic energy at the faster speed.
Firstly, we need to know the mass of the boy’s body. We can do this by using the kinetic energy formula;
Mathematically;
K.E = 1/2 * m * v^2
From the question;
K.E = 40 Joules
m = ?
v = speed = 2 m/s
Now, plugging these values into the kinetic energy equation, we have;
40 = 1/2 * m * 2^2
40 = 1/2 * m * 4
40 = 4m/2
4m = 40 * 2
4m = 80
m = 80/4
m = 20 kg
Now that we know the mass of the boy’s body, we can proceed to calculate the new K.E
Let’s follow the third statement in the question;
We were told that he doubles his speed upon sighting his friend.
Recall, he was traveling at a speed of 2 m/s.
Now doubling this means the new speed will
be 2 * 2 = 4 m/s
Now, we want to calculate the kinetic energy value at this new speed.
Mathematically, we use the same formula for kinetic energy.
K.E = 1/2 * m * v^2
We know that m is the mass that we calculated as 20kg and our v here is 4 m/s
Plugging these values, we have;
K.E = 1/2 * 20 * 4^2
K.E = (20 * 16)/2
K.E = 320/2
K.E = 160 J
Answer:
A boy weighing 20 kilograms is riding a skateboard. He’s moving at 2 meters/second and has 40 joules of kinetic energy. He doubles his speed when he sees his friends ahead of him. His kinetic energy at the faster speed is 160 joules.

What is the measure of angle X?
====================================================
Explanation:
Focus on triangle BDH
Interior angles B and D are given to be 40 and 31 respectively. Interior angle H is unknown
For any triangle, the interior angles always add to 180
B+D+H = 180
40+31+H = 180
H+71 = 180
H = 180-71
H = 109
Interior angle H is 109 degrees for triangle BDH
The exterior angle is 180 minus this measure
exterior angle = 180 - (interior angle)
exterior angle = 180 - 109
exterior angle = 71
Note how this is the sum of interior angles B and D, so you could use the remote interior angle theorem here.

Answer:
If there are 1500 students in your school then 960 students would enjoy watching TV
Step-by-step explanation:
Step 1: We know that 64% of kids aged from 11 to 15 enjoy watching TV and there is 1500 students in your school
Step 2: We now want to find 64% of 1500, we can rewrite 64% as 0.64. We multiple 1500 by 0.64 to find out how many students enjoy watching TV
0.64 x 1500 = # of students who like watching TV
960 = # of students who like watching TV
Therefore out of 1500 students, 960 would enjoy watching TV

A way to find the equation of the graph is to find the solutions.
On the graph, the solutions are where the function intersects the x-axis. That would be where x = -2, x = 1, and x = 3.
In the equations, you will need to find factors when the x is inputted, the factor equals 0. For example, one of the factors is (x + 2). This is because x + 2 = 0, so x = 0 - 2, so x = -2. So, the three factors are (x + 2), (x - 1), and (x - 3).
The correct equation is A.

In ΔABC, and m∠ABC = 90°. D and E are the midpoints of and , respectively. If the length of is 9 units, the length of is units and m∠CAB is °.
Applying the midsegment theorem and the definition of isosceles triangle:
DE = 4.5 units
m∠CAB = 45°
The image that shows ΔABC is attached below.
Since AB = BC, therefore, ΔABC is an isosceles triangle.
This implies that, the base angles will be equal.
Thus:
If m∠ABC = 90°, therefore,
m∠CAB = ½(180 - 90)
m∠CAB = 45°.
DE is the midsegment of the triangle, and is parallel to the third side, CA = 9 units.
Based on the midsegment theorem, we have the following equation:
DE = ½(9)
DE = 4.5 units.
Therefore, applying the midsegment theorem and the definition of isosceles triangle:
DE = 4.5 units
m∠CAB = 45°

Answer:2/6, 7/21, 15/45
Step-by-step explanation:
So we know that 6,21,45 are all multiples of 3
To find the numerator we have to divide each multiple by 3
so for the first one it would be 6/3 which is 2. So 2 is the numerator and the answer for the first one is 2/6
now we have to do the same method for the next fraction so we do 21/3=7
so the numerator is 7 and the fraction is 7/21
now for the last one we have to do the same method again
45/3=15 so the numerator is 15 and the answer is 15/45
You can use this method for any question like this
so the final answers are 1/3=2/6=7/21=15/45
