Answer:
0.2
Step-by-step explanation:
Given:
Total number of students = 20
Number of students who have brown hair = 12
Number of students who have blonde hair = 4
Number of students who have red hair = 3
Number of students who have black hair = 1
To find:
Probability of randomly selecting a blonde-haired student from the classroom.
Solution:
Probability refers to chances of occurring of some event.
Probability = Number of favourable outcomes/ Total number of outcomes
Number of favourable outcomes ( Number of students who have blonde hair ) = 4
Total number of outcomes = 20
So,
Probability of randomly selecting a blonde haired student from the classroom =
Answer:
○ C. The lines are perpendicular.
Step-by-step explanation:
In order for equations to be perpendicular, their <em>rate of changes</em> [<em>slopes</em>] must be OPPOSITE <em>MULTIPLICATIVE</em><em> </em><em>INVERSES</em>, which in this case is so:
− to +}
> OPPOSITE
+ to −}
MULTIPLICATIVE INVERSE [RECIPROCAL]

Answer:
D
Step-by-step explanation:
sampling distribution is statistical representation of statistics of each sample. So for a class size of 30,
A. number of samples have to be very large and defined in sampling distribtuion so this option is nullified
B. sample collection in sampling distribution is done without replacement of individuals so this option is nullified
C. this explanation doesn't match with the definition so this option is nullified
D. It is the correct option
The amount of water that has entered the pool over these five minutes is 42.5 gallons.
Given the rate at which water enter the pool W(t). To calculate the amount of water that has entered the pool over these five minutes, we integrate W(t) over the interval t = 0 to t = 5.
The amount of water that has entered the pool over these five minutes is 42.5 gallons.

Answer:
Step-by-step explanation:
Points are said to be collinear if they all lie on a line .
Let points L , M, N be collinear i.e they all lie on a line .
Consider the following figure :
Given :
LN = 54 units
LM = 31 units
To find : MN
Solution :
Clearly we can see LM + MN and LN coincides each other and we know that two things which coincide are equal to each other .
Therefore , LM + MN = LN
31 + MN = 54
On transposing 31 to RHS , we get MN = 54-31 = 23 units
{ Transposition is basically a process of taking one number from side to the other with the opposite operation }
