Answer:
[tex]Pr = \frac{3}{36}[/tex]
Step-by-step explanation:
Given
2 number die
Required
P(Sum = 4)
The sample space of 2 die is:
[tex]S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6), (2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)[/tex]
[tex](3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6), (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)[/tex]
[tex](5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6), (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)[/tex]
[tex]n(S)= 36[/tex]
The pairs that adds up to 4 are:
[tex]Sum(4) = \{(1,3), (2,2),(3,1)\}[/tex]
[tex]n(Sum) =3[/tex]
So, the probability is:
[tex]Pr = \frac{n(Sum)}{n(S)}[/tex]
[tex]Pr = \frac{3}{36}[/tex]

Answer: a^3 · a^2 ≠ a^6 as the laws of exponents states that the multiplication rule for two exponents with the same bases equates to addition, so that a^3 · a^2 = a^3+2 = a^5.
Express the series using sigma notation. 1 + 4 + 16 + ... + 256.
a.
c.

d.
Please select the best answer from the choices provided
A
B
C
D
Answer:
D
Step-by-step explanation:
By looking at the terms, we can notice that each term is 4 times the previous term. This means the series is geometric and we can rule out options A and B because of this. We can find the first terms of both options C and D to get:
first term c: 4
first term d: 1
The first term of our series is one, so that must mean D is the answer.
The sample space of picking a 2
character password using the letters Y, P, GR,
B, O, where double letters are not allowed is
shown. Your teacher asks the class to find the
probability of choosing a password with
one Y and one P. Carlos incorrectly says that
the probability is 15. Find the correct probability
then decide which error Carlos might have
made
Answer:
[tex]Pr = \frac{1}{15}[/tex]
Step-by-step explanation:
Given
See attachment for sample space
Required
[tex]P(1\ Y\ and\ 1\ P)[/tex]
From the attached sample space, we have:
[tex]n(S) =30[/tex] ---- total outcomes
[tex]n(PY) = 2[/tex] --- outcomes with 1 Y and 1 P = 2 i.e. (P,Y) and (Y,P)
So, the required probability is:
[tex]Pr = \frac{n(PY)}{n(S)}[/tex]
[tex]Pr = \frac{2}{30}[/tex]
[tex]Pr = \frac{1}{15}[/tex]
The error is that; Carlos omitted the numerator

Write 11 k-6 (2k+5)in expanded form and find the sum
Answer:
Option B
Step-by-step explanation:
Expression representing the series is,
[tex]\sum_{k=6}^{11}(2k+5)[/tex]
Here, k = Number of terms
By placing k = 6, 7, 8, 9, 10, 11 in the expression we can get the terms of the series.
For k = 6,
(2k + 5) = 2(6) + 5
= 17
For k = 7,
(2k + 5) = 2(7) + 5
= 19
For k = 8,
(2k + 5) = 2(8) + 5
= 21
For k = 9,
(2k + 5) = 2(9) + 5
= 23
For k = 10,
0(2k + 5) = 2(10) + 5
= 25
For k = 11,
(2k + 5) = 2(11) + 5
= 27
Therefore, expanded form will be,
17, 19, 21, 23, 25, 27
There, is a common difference in each successive to previous term,
d = 19 - 17
d = 2
Number of terms 'n' = 6
First term = 17
Sum of an arithmetic sequence is given by,
[tex]S=\frac{n}{2}[2a+(n-1)d][/tex]
Therefore, sum of the given sequence will be,
[tex]S=\frac{6}{2}[2(17)+(6-1)2][/tex]
= 3(34 + 10)
S = 132
Option B will be the correct option.
A party planner bought 30 meters of ribbon to make bows. She uses 20 centimeters of ribbon to make 1 bow. What is the total number of bows the party planner can make with 30 meters of ribbon?
A. 15
B. 150
C. 1,500
D. 15,000
Answer:
B. 150
Step-by-step explanation:
1 meter = 100 centimeters
since there is 30 meters x 100 centimeters = 3000 centimeters
then divde by 20 centimeters since that is the cost to make 1 bow so
3000 / 20 = 150.
So 150 bows in total.

. if 3, 2, y, 10 are in proportion, find the value of y
Answer:
y = 15
Step-by-step explanation:
Given :
3, 2, y, 10
If the numbers are in proportion :
We can thus say :
3/2 = y/10
Cross multiply
3 * 10 = 2 * y
30 = 2y
Divide both sides by 2
30 / 2 = 2y / 2
15 = y

How much would you need to deposit into an account that pays 6.5% interest compounded semiannually to have $10,000 after 7 years?
Answer:
6390.56
Step-by-step explanation:
[tex]AV=PV(1+\frac{i}{n})^{nt}\\10000=x(1+\frac{.065}{2})^{7*2}\\10000=1.564807232*x\\6390.53=x[/tex]
9514 1404 393
Answer:
$6490.57
Step-by-step explanation:
The future value is given by the compound interest formula ...
A = P(1 +r/n)^(nt)
Principal P earns annual rate r compounded n times per year for t years.
Filling in the given values, we have ...
10000 = P(1 +0.065/2)^(2·7) = P(1.0325^14)
P = 10000/1.0325^14 ≈ 6390.5635
You would need to deposit $6390.57 into the account to have $10,000 in 7 years.
_____
Additional comment
Using the rounded-down result of the computation will result in a value after 7 years of $9,999.99, not quite $10,000. Rounding the computed value up to $6390.57 ensures the account balance will actually be $10,000.00 after 7 years.
If the balance is rounded to the nearest penny each time interest is added, then the balance after 7 years will be exactly $10,000.00. If there is no intermediate rounding, the resulting balance will be $10,000.01.
Most of the time, the answer key doesn't pay attention to details like this. Your expected answer may be $6390.56, or $6391 if rounded to dollars.

please help will mark brainlist!!
Answer:
x=28
y=28
Step-by-step explanation:
Equation 1:
Dived both sides by 0.75 to remove 3/4 from x.
(x-12)=16
Now, add 12 to both sides.
x=28
Equation 2:
Same here, divide both sides by 0.75.
y-12=16
Add 12 to both sides.
y=28
