Probability of getting the sum as 4 when a pair of dice is rolled is 1/12.
Define probability.A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.
Value of probability can be greater than 1?No, probability is aways between 0 to 1.
Find total number of possible outcomes
Here it is given that a pair of dice is rolled
So the event points are
= { (1,1), (1,2), (1,3), (1,4),(1,5),(1,6),(2,1), (2,2), (2,3), (2,4),(2,5),(2,6),(3,1), (3,2), (3,3), (3,4),(3,5),(3,6),(4,1), (4,2), (4,3), (4,4),(4,5),(4,6),(5,1), (5,2), (5,3), (5,4),(5,5),(5,6),(6,1), (6,2), (6,3), (6,4),(6,5),(6,6)}
So the total number of possible outcomes = 36
Let A be the event that of getting a sum of 4
So the event points are (1,3) , (2,2) , (3,1)
So total number of possible outcomes for the event A is 3
Hence the required probability= P(A)= no. of favorable cases to event A/total no of outcomes
=3/36
=1/12

Use the quadratic formula to find the solutions.
[tex]\frac{-b+\sqrt{b^2-4ac} }{2a}[/tex] or [tex]\frac{-b-\sqrt{b^2-4ac} }{2a}[/tex]
Substitute the values a = 6 , b = − 17 , and c = 5 into the quadratic formula and solve for x .
17 ±sqrt(-17)^2-4*(6*5)

The manager of a school store orders 250 pencils at the beginning of the
school year to sell to students. The function f(x) = 250 – 7x represents the
number of pencils remaining after I days of school.
How many pencils are remaining after 14 days of school?
Answer:
152 pencils remain after 14 days of school.
Step-by-step explanation:
Replace x in this formula with 14 (14 days):
f(14) = 250 - 7(14) = 250 - 98 = 152
152 pencils remain after 14 days of school.

A standardized test is designed so that scores have a mean of 50 and a standard deviation of 4.
What percent of scores are between 46 and 54?
Answer:
68.3%
Step-by-step explanation:
Using the relation :
Zscore = (x - Mean) / standard deviation
For, x between 46 and 54
Zscore = ((54 - 50) / 4) - ((46 - 50) / 4)
P(Z < 4/4) - P(Z < -4/4)
P(Z < 1) - P(Z <-1)
0.84134 - 0.15866
= 0.68268
= 0.68268 * 100%

Two numerical patterns are shown below:
Pattern A: 6, 12, 18, 24, 30
Pattern B: 12, 24, 36, 48, 60
Select the statement that describes the numerical patterns.
The rule for Pattern B is "multiply by 2."
The rule for Pattern A is "multiply by 2."
Each term in Pattern B is one half the corresponding term in Pattern A.
Each term in Pattern A is one half the corresponding term in Pattern B.
Answer:
ITS A
i took the quiz :)
Step-by-step explanation:
The two true statements are:
The rule for Pattern B is "multiply by 2."
Each term in Pattern A is one-half the corresponding term in Pattern B.
Wich statements are the correct ones?
Here we have two patterns:
Pattern A: 6, 12, 18, 24, 30Pattern B: 12, 24, 36, 48, 60First, let's analyze the patterns. For pattern A we can see that we just add 6 to each consecutive term, so this is an arithmetic sequence.
6 + 6 = 12
12 + 6 = 18
18 + 6 = 24
And so on.
For pattern B we multiply each term by 2 to get the next one, so this is a geometric sequence.
2*12 = 24
2*24 = 48
and so on.
Then we already can see that. "The rule for Pattern B is "multiply by 2." Is true
And:
The rule for Pattern A is "multiply by 2." is false.
Finally, let's compare the terms. The first term of B is 12, and the first ter of A is 6, so we can see that the first term of B is two times the first one of A. The second term of B is 24, while the second of A is 12, so again, we can see that the second term of B is two times the second of A.
So we can see a pattern, meaning that the statement: "Each term in Pattern A is one-half the corresponding term in Pattern B."
