9n+13=3n+62.2
WHATS THE ANSWER PLEASE
Answer:
n = 8.2
Step-by-step explanation:
9n +13 = 3n + 62.2
=
9n = 3n +62.2 -13
=
9n - 3n = 62.2-13
=
6n = 49.2
=
n = 49.2/6 = 8.2

Could you put this in english so that i'm able to answer..?
Step-by-step explanation:
Suppose that we have a sample space S5 {E1, E2, E3, E4E4E, E5, E6, E7}, where E1, E2, . . ., E7 denote the sample points. The following probability assignments apply: P(E1) 5 .05, P(E2) 5 .20, P(E3) 5 .20, P(E4) 5 .25, P(E5) 5.15, P(E6) 5 .10, and P(E7) 5 .05. LetA5{E1,E4E4E,E6}B5{E2E2E,E4E4E,E7E7E}C5{E2E2E,E3,E5,E7E7E}a.Find P(A(A(), P(B), and P(C).b.Find AB and P(A(A(>B).d.Are events A and C mutually exclusive?C mutually exclusive?Ce.Find Bc and P(Bc).
Answer:
P(A) = 0.4 ; P(B) = 0.50 ; P(C) = 0.60 ; P(A u B) = 0.65 ; P(A n B) = 0.25 ;
A and C are mutually exclusive ;
0.5
Step-by-step explanation:
S = {E1, E2, E3, E4, E5, E6, E7}
P(E1) = .05, P(E2) = .20, P(E3) = .20, P(E4) = .25, P(E5) = .15, P(E6) = .10, and P(E7) = .05
Let:
A{E1,E4,E6}
B{E2,E4,E7}
C{E2,E3,E5,E7}
P(A) = 0.05 + 0.25 + 0.10 = 0.40
P(B) = 0.20 + 0.25 + 0.05 = 0.50
P(C) = 0.20 + 0.20 + 0.15 + 0.05 = 0.60
AUB = {E1, E2, E4, E6, E7}
P(A u B) = 0.05 + 0.20 + 0.25 + 0.10 + 0.05 = 0.65
AnB = {E4}
P(A n B) = 0.25
A and C are mutually exclusive if AnC = ∅
A n C = ∅
Hence, A and C are mutually exclusive.
B complement = B' = {E1, E3, E5, E6}
P(B') = 0.05 + 0.20 + 0.15 + 0.10 = 0.5

6
O-5 and -3
5
O 5 and 3
O-8 and 5
O 0 and 5
Answer:
-3 and -5
Step-by-step explanation:
The zeros are where the line touches the x-axis
From the graph we can see that the line touches those points.
You can also determine it from the equation because the equation is in factored form, which is (x-r1)(x-r2)
Remember that it is minus so although it is +3 and +5 the actual zero is negative!!

Help please im stuck
Answer:
-2x + 6y = 3
4x + 3y = 9
Answer: 2
Explanation:
-2(2)x + 6y = 3
4x + 3y = 9
-8x + 10y = 16
-4x - 5y = 13
Answer: -1/2
Explanation:
-8(-1/2)x + 10y = 16
-4x - 5y = 13
3x - 8y = 1
6x + 5y = 12
Answer: -2
Explanation:
3(-2)x - 8y = 1
6x + 5y = 12
10x - 4y = -8
-5x + 6y + = 10
Answer: 1/2
Explanation:
10(1/2)x - 4y = -8
-5x + 6y + = 10

Answer:
L = 5[tex]\sqrt{10}[/tex]
Step-by-step explanation:
use Pythagorean Theorem:
L² + (5[tex]\sqrt{2}[/tex])² = (10[tex]\sqrt{3}[/tex])²
L² + 25(2) = 100(3)
L² + 50 = 300
L² = 250
L = [tex]\sqrt{250}[/tex] = [tex]\sqrt{25}[/tex] · [tex]\sqrt{10}[/tex] = 5[tex]\sqrt{10}[/tex]
Answer:
by Pythagoras law
(10√3)²=l²+(5√2)²
100×3-25×2=l²
l²=25o
l=√250=5√10
:.l=5√10

Solve the system of equations using elimination
Answer:
(1, 3).
Step-by-step explanation:
x + 2y = 7
3x - 2y = -3
Adding the 2 equations will eliminate y:
4x = 4
x = 4/4
x = 1
Plug x = 1 into the first equation:
1 + 2y = 7
2y = 6
y = 3.
The Courtney family wants to expand their rectangular patio, which currently measures 13ftby 18 ft. They want to extend the length and width by the same amount to increase the total areaby 140 ft squared. Write a quadratic equation that models the situation. YOU DO NOT HAVE TO SOLVE.
Answer:
hi
Step-by-step explanation:
et the number of feet they are going to expand the width and length of the patio. ... But, we also know form our problem that they want to increase the total area of the patio by 160 ... Now we can equate the expanded area of the patio and simplify: ... Write the quadratic equation in standard form: x^2- 1 = -7x.
