The statement "Two lines intersect at a point" is a correct option (B) that would be the best choice.
What are the null hypothesis and alternative hypothesis?The null and alternative hypotheses are two generalizations about a population that are strictly contradictory. The null hypothesis can be denoted by H₀ and the alternative hypothesis can be denoted by H₁.
It is given that:
If the statement is rewritten as a conditional statement in if-then form.
As we know,
From the definition of the hypothesis.
The null and alternative hypotheses are two generalizations about a population that are strictly contradictory
The hypothesis is best described as two lines intersecting at a point if the original sentence is restated as a conditional statement in the if-then format.
Thus, the statement "Two lines intersect at a point" is the correct option (B) that would be the best choice.

Solve the quadratic equation by completing the square.
x2 + 8x + 19 = 0
What’s the answer ? Math algebra 2
Answer: x= 4 ± [tex]\sqrt{-3}[/tex]
Step-by-step explanation:
[tex]x^{2}[/tex] + 8x + 19 = 0 First subtract 19 from both sides
-19 -19
[tex]x^{2}[/tex] + 8x = -19 Now to complete the square on the left side you will divide 8 by 2 and square the number that you will get and add it to both sides. If you divide 8 by 2 you get 4 and 4 squared is 16 .So add 16 to both sides.
x^2 + 8x + 16 = -19 + 16 Now factor the left side
(x+4)^2 = -3 Take the square root of both sides
(x+4) = ±[tex]\sqrt{-3}[/tex]
Subtract 4 from both sides
x = ±[tex]\sqrt{-3} - 4[/tex]

rote x+18=x-2 what is the answer
Answer:
no solution
Step-by-step explanation:
Given
x + 18 = x - 2 ( subtract 18 from both sides )
x = x - 20 ( subtract x from both sides )
0 = - 20 ← not possible
This indicates the equation has no solution

Answer:
≠
Step-by-step explanation:
10 * 7 - 3 ____ 10 * (7 - 3)
70 - 3 ____ 10 * (7 - 3)
67 ____ 10 * (7 - 3)
67 ____ 10 * 4
67 ____ 40
67 ≠ 40
Answer is ≠
this is because of the order you do a problem.
1. P - paranthesis
2. E - exponents
3. MD - multiplication division (whatever comes first)
4. AS - addition subtraction (whatever comes first)
There are no paranthesis in the first one so you multiply first.
There are paranthesis in the second one so you add first.
That gives you a different answer for each making it unequal.

What is the domain of the function y=3sqt?
Answer:
y=3sqrt(x)
x≥0
Step-by-step explanation:
The domain of a function refers to all values of x for which y is defined.
Since this is a square root function, we need to keep the expression under the square root sign to be greater than or equal to zero.
As soon as the expression under the root sign is less than zero, the function will not be defined.
This means that the square root of a negative number will not be a real number.

12. Describe how you would write 3,482,000,000 in scientific notation as if you were explaining it to someone who didn't know what scientific notation was.
just move the decimal point where the exponent indicates
there are no negative exponents here so none of these numbers will be decimal:
8. 6430, moved the decimal point 3 places to the right
9. 84560000 moved the decimal point 7 places to the right
10. 800000 (six zeros)
11. 90000000000 (ten zeros)
12. 3.482^9 (I'll use this one as example)
To convert a number to scientific notation, move the point just after the first number from left to right (that is not zero), remove the zeros that are from right to left if there are any (for example, if you have 45002 it is not needed to remove any because there is a significant number is in front of the two zeros, instead, if we have a number like 2046000, the last three zeros are removed).
there you will have the number: 3.482
Then, count how many places the point moved (in the original number) and that will be the exponent
3,482,000,000
moved 9 places
this isn't a decimal number so the exponent will be positive
3.482^9
simplify 3/2√3 a. √2/3 b. 2√3/3 c. 3√3/3 d. √3/2 -everything is in fraction form-
Answer:
Before A:[tex]\frac{3\sqrt{3}}{6}[/tex]
A:Already Simplified!
B:Also, Already Simplified! Can be changed to [tex]\frac{\sqrt{12}}{3}[/tex]
C:Already Simplified, yet again. Can be changed to[tex]\frac{\sqrt{27}}{3}[/tex]
D:Already Simplified.
Step-by-step explanation:
For Before A, I multiplied both denominator and numerator by square root of 3. The multiplication moved the square root to the numerator, simplifying the fraction.
The different forms of B and C are just that I multiplied the square of the first number into the square roots. This is OK because the square root of a number's square is the number itself. Therefore, you can multiply a square root by the square of the number from outside the root.
It’s all in the picture number 5!!!pleaseee help‼️‼️‼️‼️‼️‼️ASAP‼️‼️
We know that m<JKL = m<JKM + m<MKL
Let's substitute the values from the picture into our equation above.
10x - 11 = 43 + 8x - 20
Combine like terms.
10x - 11 = 8x + 23
Subtract 8x from both sides and add 11 to both sides.
2x = 34
Divide both sides by 2
x = 17
m<MKL = 8x - 20 = 8(17) - 20 = 136 - 20 = 116 degrees.
m<JKL = 10x - 11 = 10(17) - 11 = 170 - 11 = 159 degrees.
Rocco can do 60 jumping jacks in 1 minute. How many jumping jacks can he do
in 8 minutes?
Answer: 480 Jumping jacks
Step-by-step explanation: What I did was 60 * 8= 480
60 Jumping Jacks=1 minutes
120 Jumping Jacks=2 minutes
continue, continue
The number of jumping jacks can he do in 8 minutes is 480 if Rocco can do 60 jumping jacks in 1 minute.
What is a fraction?Fraction number consists of two parts, one is the top of the fraction number which is called the numerator and the second is the bottom of the fraction number which is called the denominator.
It is given that:
Rocco can do 60 jumping jacks in 1 minute.
60 Jumping Jacks = 1 minutes
120 Jumping Jacks = 2 minutes
= 60x8
= 480
Thus, the number of the jumping jacks is 480.
