Event A: Rolling a number less than 4 on a number cube Event B: Flipping heads on a coin toss What is the probability of A, the probability of B, and the probability of both A and B?
P(A) =
P(B) =
P(A and B) =
Answer:
first one is 1/2
the next one is 1/2
the last one is 1/4
Step-by-step explanation:
i just did it
The probability of A will be P(A) = 1/2. The probability of B will be P(B) = 1/2. The probability of A and B will be P(A and B) = 1/4
What is the probability?Probability refers to a possibility that deals with the occurrence of random events.
The probability of all the events occurring need to be 1.
The formula of probability is defined as the ratio of a number of favorable outcomes to the total number of outcomes.
P(E) = Number of favorable outcomes / total number of outcomes
Event A: Rolling a number less than 4 on a number cube.
Event B: Flipping heads on a coin toss
We need to find the probability of A, the probability of B, and the probability of both A and B.
The probability of A will be
P(A) = 1/2
The probability of B will be
P(B) = 1/2
The probability of A and B will be
P(A and B) = 1/2 x 1/2
P(A and B) = 1/4

Given the vertex of a parabola is (-3,1) and also contains the point (-4,-1). State the exact equation of the parabola in vertex form, show all your work.
Answer:
y = -2(x + 3)^2 - 1
Step-by-step explanation:
The vertex equation of a parabola is y = a(x - h)^2 + k. If the vertex here is (-3, 1), then this equation becomes y = a(x + 3)^2 + 1.
Knowing that the graph passes through (-4, -1), we let y = -1 and x = -4, obtaining:
-1 = a(-4 + 3)^2 - 1, which must be solved for a:
-1 = a - 1. Therefore, a = -2, and the exact equation of this parabola is:
y = -2(x + 3)^2 - 1
All statements of equality below are correct.
A.True
B.False

Find the distance between the pair of points (-6.-17) and (-8.-19) The distance is (Round to the nearest thousandth as needed.)
Answer:
2.83
Step-by-step explanation:
d= Square root of (x2 - x1 )^2 +( y2- y1)^2
from the point given you
x1= -6
y1 = -17
x2 = -8
y2 = -19
by applying the formula
Square root of ( -8 - (-6))^2 + ( -19 - (-17))^2
Square root of (-8+6) + (-19+17)^2

find 5 rational number between 2/-7 and 5/6
Answer:
-11/42, -10/42, 10/42, 11/42, 12/42
Step-by-step explanation:
First of let's find the LCM of the denominators.
LCM of 6 and 7 is 42
Thus, -2/7 can also be expressed in terms of 42 as denominator as; -12/42
Similarly, 5/6 can also be expressed in terms of 42 as denominator as; 35/42
Thus, any five rational numbers could come in the form of the numerator being between -12 to 35 with the denominator being 42.
Thus, five rational numbers between -2/7 and 5/6 are;
-11/42, -10/42, 10/42, 11/42, 12/42

George bought a model of a Viking ship for $68. If he paid
$5.10 in sales tax, what was the sales tax rate?
Answer:
We can convert 6.75% to a decimal by dividing by 100.
If x is the price of the house, then the sales tax is 0.0675x. The price of the house and the sales tax add up to $319,000.
x+0.0675x=319,000
Combe terms on the left.
1.0675x=319,000
Finally, divide both sides by 1.0675.
x=319,0001.0675=298,829.04

Translate the following sentence into an equation using n for the unknown number. Then solve for n.
when 15 is decreased by three times a number, the result is 21
a.
15 - 372 = 21
n = -2
b.
312 - 15 = 21
n = -2
C.
31 - 15 = 21
n = 12
d.
15 - 3n2 = 21
n-2
Given:
15 is decreased by three times a number, the result is 21.
To find:
The equation for the given statement and solve it.
Solution:
Let n be the unknown number. Then,
Three times of a number = [tex]3n[/tex]
15 is decreased by three times a number = [tex]15-3n[/tex]
It is given given that the result after subtraction is 21. So,
[tex]15-3n=21[/tex]
[tex]-3n=21-15[/tex]
[tex]-3n=6[/tex]
Divide both sides by -3.
[tex]n=\dfrac{6}{-3}[/tex]
[tex]n=-2[/tex]
Therefore, the required equation is [tex]15-3n=21[/tex] and its solution is [tex]n=-2[/tex]. Hence, the correct option is (a).
