Answer:
1/8
Step-by-step explanation:
A “standard number cube” has six sides, marked 1 2 3 4 5 and 6. Of those, exactly half are even and exactly half are odd, so we can dispense with the 6 part and just go 1/2 (the same as 3/6, after all)
So the first roll is even half the time. If it is, the second roll is odd half the time, so the chances of an even then odd pair are 1/2*1/2=1/4.
If those two happen in the correct order, the chances of the third roll being even are again 1/2… so we have 1/2*1/2*1/2=1/8
Hope it helps
The length of this rectangle is 2sqrt19, the width of the rectangle is sqrt19. The value of its perimeter is?
Answer:
P = 6[tex]\sqrt{19}[/tex] units
A = 38 sq units
Step-by-step explanation:
P = 2[tex]\sqrt{19}[/tex] + 2[tex]\sqrt{19}[/tex] + 1[tex]\sqrt{19}[/tex] + 1[tex]\sqrt{19}[/tex]
P = 6[tex]\sqrt{19}[/tex]
A = 2[tex]\sqrt{19}[/tex] · [tex]\sqrt{19}[/tex]
A = 2 (19)
A = 38 sq units

1. Erwin hiked 5/7 of a kilometer while
Jericho hiked 2/3 of a kilometer. How many
kilometers did they hiked in all?
Asked/ Problem: How many kilometers did
they hiked in all?
Answer:
the number of kilometers hiked in all is [tex]\frac{29}{21}[/tex]
Step-by-step explanation:
The computation of the number of kilometers hiked in all is shown below:
= Erwin + Jericho
[tex]= \frac{5}{7} + \frac{2}{3}\\\\= \frac{15 + 14}{21} \\\\= \frac{29}{21}[/tex]
Hence, the number of kilometers hiked in all is [tex]\frac{29}{21}[/tex]

The Jets play 16 football games this season. So far they have 3 wins and 4 losses. If they can win all the rest, how many wins and losses will they have for the season?
Answer:
12 wins and 4 losses
Step-by-step explanation:
3 wins and 4 losses means they have played so far 7 games.
They play a total of 16 games in a season.
16 - 7 = 9
They still have to play 9 more games.
Add 9 wins to the 3 wins.
9 + 3 = 12
That means they'd finish the season with 12 wins and 4 losses.
Hurry can somebody give me the answer please it’s due at 11:59
Answer:
Question 1: (1,5) (I believe that is the format they are looking for.)
Question 2: (5,7)
Step-by-step explanation:
Just substitute the letters for the numbers they give you then solve.
Question 1:
y = 5
5 = x + 4 Subtract 4 from both sides.
1 = x
Question 2:
x = 5
y = 2 · 5 - 3
y = 10 - 3
y = 7

Factor the expression using the GCF.
42n – 27s
Answer: 3
Step-by-step explanation:
The fully factored form of the expression 42n - 27s is 3 (14n - 9s).
What is an expression?An expression contains one or more terms with addition, subtraction, multiplication, and division.
We always combine the like terms in an expression when we simplify.
We also keep all the like terms on one side of the expression if we are dealing with two sides of an expression.
Example:
1 + 3x + 4y = 7 is an expression.
3 + 4 is an expression.
2 x 4 + 6 x 7 – 9 is an expression.
33 + 77 – 88 is an expression.
We have,
To factor the expression 42n - 27s using the GCF (Greatest Common Factor),
We first need to find the GCF of the two terms.
The factors of 42 are 1, 2, 3, 6, 7, 14, 21, and 42,
The factors of 27 are 1, 3, 9, and 27.
The common factors of 42 and 27 are 1 and 3.
Now,
The GCF of 42n and 27s is 3.
We can factor out 3 from both terms:
42n - 27s
= 3(14n - 9s)
Therefore,
The fully factored form of the expression 42n - 27s is 3(14n - 9s).

The question is incomplete. Here is the complete question.
You are designing an automatic coin counter that stacks 50 pennies at a time to be placed in coin wrappers. You plan on measuring the height of the stack to determine the number of coins, but are concerned as to how accurate the method will be. You measure the thickness of 30 penniesm with the data listed below.
a. Based on these data, estimate the height of a stack of any 50 pennies. How accurate is your estimate, at 95% confidence?
b. What percentage of pennies from the population have thickness of at least 1.34mm?
Answer: a. Height = 74.25mm with margin of error of 0.021.
b. 99.38%
Step-by-step explanation:
a. To estimate the height of any 50 pennies, we have to determine the average of thickness of the sample given in the table.
Average is calculated as the sum of all the data divided by the quantity the sample has, so:
[tex]\overline{x}=\frac{\Sigma x}{n}[/tex]
[tex]\overline{x}=\frac{44.56}{30}[/tex]
[tex]\overline{x}=1.485[/tex]
Each coin is estimated to have 1.485 mm of thickness. Then, the height of 50 pennies is
h = 1.485*50
h = 74.25
50 pennies will have an estimate height of 74.25 mm.
Margin of Error expresses the amount of random sampling error the results in a survey can have. It will show how many percentage points the result is from the actual population value.
To calculate it, we have to determine standard deviation of the data.
Standard deviation is
[tex]s=\sqrt{\frac{\Sigma (x-\overline{x})^{2}}{n-1} }[/tex]
[tex]s=\sqrt{\frac{0.09735}{29} }[/tex]
s = 0.058
For a 95% confidence, z-score is 1.96.
Margin is
[tex]E=z.\frac{s}{\sqrt{n}}[/tex]
[tex]E=1.96(\frac{0.058}{\sqrt{30}})[/tex]
E = 0.021
The accuracy of the estimate is 2.1%.
b. The percentage of pennies with thickness at least 1.34mm is represented as P(x>1.34). To calculate it:
P(x>1.34) = 1 - P(x<1.34)
Now, we have to normalize the data:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
[tex]z=\frac{1.34-1.485}{0.058}[/tex]
[tex]z=-2.5[/tex]
[tex]P(x<1.34)=P(z<-2.5)[/tex]
Consulting the z table,
[tex]P(z<-2.5)=[/tex] 0.00621
Now, for the percentage:
[tex]P(x>1.34)=1-0.00621[/tex]
P(x > 1.34) = 0.9938 or 99.38%
The percentage of pennies with thickness of at least 1.34mm is 99.38%.
