The probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.
What is probability?Probability of an event is the ratio of number of favorable outcome to the total number of outcome of that event. The probability of an event can not be more than the number 1.
John is playing a game of darts. In this game of dart,
The probability that he throws a dart into the center of the dart board (the Bull’s eye) is 1/10. The probability that he throws the dart into the 10-point ring is 3/10.The probability that he either hits a Bull’s eye or scores 10 points is equal to the sum of the probability he hits the bull's eye and the probability that he throws the dart into the 10-points ring.
Let, the probability that he either hits a Bull’s eye or scores 10 points is P. Thus,
[tex]P=\dfrac{1}{10}+\dfrac{3}{10}\\P=\dfrac{4}{10}\\P=\dfrac{2}{5}[/tex]
Hence, the probability that the John either hits a Bull’s eye or scores 10 points in the game of darts is 2/5.

Complete the square for each expression. Write the resulting expression as a binomial squared. x^2-10x+_____
Answer:
[tex](x-5)^{2}[/tex]
Step-by-step explanation:
[tex]ax^{2} + bx + c[/tex]
Take the value for b, divide it by 2 and square it to get the value for c.
In this case, b = -10.
- 10 ÷ 2 = -5
-5^2 = 25
So x^2 - 10x +25 is your quadratic equation which is equal to

what is the rate of change for the numbers 3,5,7,9
Answer:
Plus 2 (+2)
Step-by-step explanation:
The rate of change is always a constant change from the given first term to the next one. In this case, you are adding 2 each time:
3 + 2 = 5
5 + 2 = 7
7 + 2 = 9
etc.
~
Change means difference in the state or condition of a thing and here the thing is number. The change made within them must be following some certain rules or patterns.
They can be uniform and here it is uniform for sure. The terms are increasing by 2 or we can say that for getting th next number, we need to add 2 with the previous.
3 + 2 = 55 + 2 = 77 + 2 = 9So, the rate of change for the above numbers or number series is +2 or addition of 2[tex].[/tex]

A truck travels 0.72 km on 0.01 litre of fuel.
How many kilometres will it travel on 1 litre of fuel?
Answer:
Your Answer is below.
Step-by-step explanation:
Okay so, can setup a proportion.
0.72 km = 0.01 L
x km = 1 L
So, solve for x
x = 0.72 km x 1 L / 0.01 L = 72 km
0.5 is what percent of 20?
Answer:
2.5%
Step-by-step explanation:
Solving
Step 1: Set up an equation.

Answer:
m = 5
n = 5
Step-by-step explanation:
Note that the ∑ of the interior angles of a triangle = 180°.
A square for one of the angles constitute as 90°.
This means that this is a isosceles triangle.
Note that for isosceles triangles, the sides will follow the rule of 1 , 1 , √2, in which √2 is the hypotenuse.
The hypotenuse is the side opposite of the greatest angle measurement. It is given that the hypotenuse for the given triangle is 5√2. Divide √2 from the given measurement to get the measurements for the legs:
[tex]\frac{5\sqrt{2} }{\sqrt{2} } = 5[/tex]
Again, as it is a isosceles triangle, the two sides will share the same measurement.
m = 5
n = 5

please help, i need to do this by today but i cant figure it out.
How would you calculate ( 2x + 1 )( x + 6 )( x - 4 ) = 2x^3 + ax^2 + bx -24
(2x+1)(x+6)(x-4)= 2x³+ax²+bx-24
(2x²+x+12x+6)(x-4) = 2x³+ax²+bx-24
2x³+x²+12x²+6x-8x²-4x-48x-24 = 2x³+ax²+bx-24
2x³+x²+12x²+6x-8x²-4x-48x-24- 2x³-ax²+bx-24=0
5x²-46x-ax²+bx-48=0
-ax²+5x²+bx-46x-48=0

40 % are boys
40 % = 50 boys
60 % = 75 girls
75 + 50 = 125

Let number of students be X
Percentage of boys=100-60=40%
No of boys= 40% of X
50= 40×X/100
X= 50 × 100/40

Step-by-step explanation:
Saturday a minor league baseball team gave away baseball cards to each person entering the stadium.On group recieved 28 baseball cards.A second group recieved 84 baseball cards.If each person entering the stadium recieved the same number lf baseball cards, what is the greatest number of baseballs cards they could have recieved?Rewrite using distrubutive property
Answer: 28
Step-by-step explanation:
Given: First group received 28 baseball cards and second group received 84 baseball cards.
Total cards= 28+84 =112
If each person entering the stadium received the same number , the greatest number of baseballs cards they could have received = G.C.D. (28,84,112)
[G.C.D. = greatest common divisor]
Since the prime factorization of 28 , 84 and 112 are as follows
28 = 2 x 2 x7
84 = 2 x 2 x 3 x 7
112 = 2 x 2 x 2 x 2 x 7
G.C.D (28, 84, 112 )= 2 x 2 x7 = 28
The greatest number of baseballs cards they could have received = 28
An angle is a right angle if it measures 30°.
Write the statement in if-then form.
Then identify the hypothesis and conclusion of the resulting conditional statement.
Finally, determine the truth value of the statement.
2. Write your own statement in if-then form. Then identify the hypothesis and conclusion of the resulting conditional statement.
Determine the truth value of the statement.
Write it’s converse to see if it’s true. If the converse is true, write a bi-conditional statement.
Answer:
1) If the measure of an angle is 30°, then it is a right angle
2) The hypothesis = The measure of an angle is 30°
The conclusion = It is a right angle
3) The statement is false
Step-by-step explanation:
1) The information given is that an angle is a right angle if it measures 30°
The statement in the if-then form can be presented as follows;
If the measure of an angle is 30°, then it is a right angle
2) The hypothesis = The measure of an angle is 30°
The conclusion = It is a right angle
3) Given that a right angle measures 90°, the compound statement; "If the measure of an angle is 30°, then it is a right angle" is false.
