Answer:
Option B.
Step-by-step explanation:
Continuous probability distribution : A probability distribution is called a continuous probability distribution, if its random variable X is a continuous variable and it can take infinite values (Real values).
Number of boxes cannot be a decimal value. So, it is not a continuous variable. Thus, option A is incorrect.
Temperature of a day is a continuous variable. So, temperature of a day can be represented using a continuous probability distribution. So, option B is correct.
Marks in a test paper cannot represent a continuous variable. Thus, option C is incorrect.
Number of students who uses the internet cannot be a fractional or decimal value. So, it is not a continuous variable. Thus, option D is incorrect.
Therefore, the correct option is B.
Answer:
Replace all occurrences of +− with a single −. A plus sign followed by a minus sign has the same mathematical meaning as a single minus sign because 1⋅−1 = −1
Y=x²−10, Y=2x−4
Eliminate the equal sides of each equation and combine.
x²−10 = 2x−4
Solve x²−10 = 2x−4 for x.
x= 1+√7, 1−√7
Evaluate Y when x = 1 + √7.
Y =−2 + 2√7
Evaluate Y when x = 1 − √7.
Y=−2 − 2√7
The solution to the system is the complete set of ordered pairs that are valid solutions.
(1+√7,−2+2√7)
(1−√7,−2−2√7)
The result can be shown in multiple forms.
Point Form:
(1+√7, −2+2√7), (1−√7, −2−2√7)
Equation Form:
x= 1+√7, y= −2+2√7
x= 1−√7, y= −2−2√7
Step-by-step explanation:
<span>No entiendo esto, esta no es una pregunta. Más que un hecho realmente.</span>
Calculating for slope:
y2-y1 = m(x2-x1)
7-2 = m(2-1)
m= 5
y=mx+b
y=5x+2
From the given information, a exists jointly proportional to b and c.
then 
Therefore, the value of a exists 2.
<h3>
What is the value of a?</h3>
Given, a exists jointly proportional to b and c.
Taking K as the constant of proportionality.
a = K b c
For b = 8 and c = 9, the value of a = 4
4 = K(8)(9)
4 = 72 K
Dividing the equation by 72, we get
Using the value of K in the equation:
Substitute the values of b = 2 and c = 18, in the above equation
a = 2
Therefore, the value of a exists 2.
