P ( H ) = 1 2/2
ON a die, the probability of getting a number less than 4:
P ( 1 , 2 , 3, 4 ) = 4 /6 P( H and no. less than 4 ) = 1 /2× 4 /6 = 1 /2 × 2/ 6 = 2/6 = 1 /3

What is the x and y intercept 3x-2y=-14
Answer:
y intercept = 14
x intercept = 4.6666....
Step-by-step explanation:
3x-2y=-14
-3x
-2y = -14 + (-3x)
*-1
2y = 14 + 3x
/2
y = 1.5x + 14
14 = y intercept
3x-2y=-14
+2y
3x = 14 + 2y
/3
x = (2/3)y + (14/3)
4.6666.... = y intercept

Answer:
Step-by-step explanation:
The ratio everything is 1:2. DE joins two midpoints. There are many properties involved in saying that. The most important for this question is that DE = 1/2 BC
That means that the sides in the small upper triangle (ADE) are 1/2 the size of the sides in the larger triangle.
So if DE = 8 then BC must be twice as big or BC = 16

Answer:
D
Step-by-step explanation:
The given line's equation is in slope-intercept form:
y = mx + b
where m = -4 is the slope, and b = -1 is the y-intercept.
The slope of the perpendicular line will be ...
-1/m = -1/(-4) = 1/4
You want the point-slope equation for the line, which is ...
y -k = m(x -h) . . . . line with slope m through point (h, k)
Your equation will have m=1/4, (h, k) = (-2, 7), so it will be ...
y -7 = 1/4(x +2)

Answer:
5√5
Step-by-step explanation:
Use the distance formula:
d = √((x2 -x1)² +(y2 -y1)²)
d = √((-7-(-2))² +(-7-3)²) = √((-5)² +(-10)²) = √(25 +100)
d = √125 = √(25·5)
d = 5√5 . . . . distance between the points
Joslyn performed an experiment using a die with its faces numbered from 1 to 6. She rolled the die and recorded whether the 5 landed face up. She repeated the process many times and kept a cumulative record of the
total number of rolls and the total number of Ss landing face up. The following table shows part of her record.
Suppose Joslyn could roll the die 10.000 times and keep a record of the total number of Ss landing face up in the 10,000 rolls What would such a record Illustrate?
Answer:
The law of large numbers
Step-by-step explanation:
The Law of large numbers states that if we observe more and more reptitiions of any chance process, the proportion of times that a specific outcome occurs approaches a single value.
The experiment embarked upon by Joselyn involving the roll of a die for a large number of trials would illustrate an experiment which illustrates the law of large numbers.
The law of large numbers simply describes the repeated performance of an experiment for a large number of trials. The law states that, as the number of experimental trials is increased, the expected value of the experiment is approached.
In Joselyn's experiment, the expected value of obtaining a 5 is 1/6. Hence, as the number of trials increases, the probability of having 5 continually approaches 1/6.
Hence, the experiment illustrates the law of large numbers.

Ishaan scored 72 on the exam.
Find the z-score for Ishaan's exam grade. Round to two decimal places.
Answer:
0.36
Step-by-step explanation:
Given that:
Mean = 70
Standard deviation = 5.5
score (x) = 72
Formular for obtaining Standardized score (Zscore) :
Zscore = [score (x) - mean] / standard deviation
Hence,
Zscore = (72 - 70) / 5.5
Zscore = 2/ 5.5
= 0.3636363
Zscore = 0.36 ( 2 decimal place)

Find the 9th term of the geometric sequence 6, 24, 96, ...
Answer:
1,572,864
Step-by-step explanation:
1. 6 x 4 = 24
2. 24 x 4 = 96
3. 96 x 4 = 384
4. 384 x 4 = 1,536
5. 1,536 x 4 = 6,144
6. 6,144 x 4 = 24,576
7. 24,576 x 4 = 98,304
8. 98,304 x 4 = 393,216
9. 393,216 x 4 = 1,572,864
The 9th term of the geometric sequence 6, 24, 96, ... is 393216
What is Sequence?A sequence is an enumerated collection of objects in which repetitions are allowed and order matters.
A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.
The given sequence 6, 24, 96, ...
