When two balanced dice are rolled, there are 36 possible outcomes. Find the probability that the first die is 3 or that doubles are rolled.
Step-by-step explanation:
The space comprising all possible outcomes (sample space) is represented by the 6×66×6 matrix formed by the possible pairs representing the outcome of dice:
From the above sample space, there are six events wherein the first die is 44 (all elements of the fourth row in the matrix). That is, n(F)=6n(F)=6. Moreover, there are six events wherein doubles are rolled (all diagonal elements in the matrix). That is, n(D)=6n(D)=6. The result (4,4)(4,4) is the intersection of both events. That is, n(D∩F)=1n(D∩F)=1.
Therefore, the possibility/probability that the first die is 4 or that doubles are rolled is computed as follows:
P(D∪F)=P(D)+P(F)−P(D∩F)=n(D)n(S)+n(F)n(S)−n(D∩F)n(S)=636+636−136=1136P(D∪F)=P(D)+P(F)−P(D∩F)=n(D)n(S)+n(F)n(S)−n(D∩F)n(S)=636+636−136=1136

A population of 2 rabbits grows at the rate of 400% every two months. How many
rabbits are in the population after 1 year?
Answer:
50 rabbits
Step-by-step explanation:
?/2 = 400/100
multiply 2 by 400
2 times 400 = 800
now, divide it by 100
800/100 = 8
every two months = 8 rabits
12 months in a year
12/ 2 equals 6
6 times 8 = 48
+the two begining rabbits
= 50 total rabbits
What is an equation of the line that passes through the points (-6, -2) and (-3, -3)?
Answer:
[tex]y = - \frac{1}{3} x - 4[/tex]
Step-by-step explanation:
The equation of a kind can be written in the slope intercept form, y= mx +c, where m is the gradient and c is the y-intercept.
[tex]\boxed{gradient = \frac{y1 - y2}{x1- x2} }[/tex]
[tex]m = \frac{ - 2 - ( - 3)}{ - 6 - ( - 3)} [/tex]
[tex]m = \frac{ - 2 + 3}{ - 6 + 3}[/tex]
[tex]m = \frac{ 1}{ - 3} [/tex]
Substitute the value of m into the equation:
[tex]y = - \frac{1}{3} x + c[/tex]
To find the value of c, substitute a pair of coordinates.
When x= -3, y= -3,
[tex] - 3 = - \frac{1}{3} ( - 3) + c[/tex]
[tex] - 3 = 1 + c[/tex]
c= -3 -1
c= -4
∴ The equation of the line is [tex]y = - \frac{1}{3} x -4[/tex].

Last Saturday an accident caused a traffic jam 13 miles long on a stretch of the
interstate.
a. How many vehicles do you think were in the traffic jam if the average car's
length measures approximately 15 feet? Explain your thinking and show all
calculations.
b. Would there be more or less vehicles if you were told there were a large
number of SUVs and trucks present in this traffic jam? Explain your thinking and
show all calculations.
There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.
What is logical reasoning?Logical or deductive reasoning involves using a given set of facts or data to deduce other facts by reasoning logically.
Given that, Last Saturday, an accident caused a traffic jam 13 miles long on a stretch of the interstate.
13 miles = 68,640 feet
One car is of 15 ft
Let there be x cars,
15x = 68,640
x = 4576
Therefore, there are 4576 cars in traffic.
If there are more SUVs and trucks, their length will be more than a car and which will make less number of vehicles involved in the traffic.
Hence, There would have been 4576 cars in the traffic. If SUVs and Trucks are involved in jam, there would be fewer vehicles.

Answer:
6x4=24
Step-by-step explanation:
solve the inequality 5(2x-1)<2(4x+3)
Answer:
x < [tex]\frac{11}{2}[/tex]
Step-by-step explanation:
=> 10x - 5 < 8x + 6
Subtract 8x from the left and right side of the inequality sign:
=> 2x - 5 < 6
Now, add 5 on both sides of the inequality:
2x < 11
now divide 2 on both sides:
x < [tex]\frac{11}{2}[/tex]

What is the perimeter of the figure please help
Answer:
A 4.5
Step-by-step explanation:
Two methods were used to teach a high school algebra course. A sample of 75 scores was selected for method 1, and a sample of 60 scores was selected for method 2. The results are:
Method 1 Method 2
Sample mean 85 83
Sample s.d. 3 2
Required:
Test whether method 1 was more successful than method 2 at the 1% level.
Answer:
Since the calculated value of t =4.629 falls in the critical region t> 2.355 we reject the null hypothesis and conclude that method 1 was more successful than method 2 at the 1% level.
Step-by-step explanation:
Applying two sample t test as both methods are independent
The null and alternate hypotheses are
H0: u1= u2 against the claim Ha: u1> u2
The significance level is 0.01 and the critical region is t > t∝( n-1)
The degrees of freedom is calculated using the formula
υ = [s₁²/n1 + s₂²/n2]²/ (s₁²/n1 )²/ n1-1 + (s₂²/n2)²/n2-1
This formula is used when the the variances are unequal.
So as we do not know anything about variances we assume they are unequal.
The calculated degrees of freedom is 132
The critical region is t > 2.355 for one tailed test.
The test statistic is
t= x1`- x2`/ √s1²/n1 + s2²/n2
t= 85-83/ √3²/75+ 2²/60
t= 2/ 0.432
t= 4.629
Since the calculated value of t =4.629 falls in the critical region t> 2.355 we reject the null hypothesis and conclude that method 1 was more successful than method 2 at the 1% level.
