how do I solve use elimination
x+3y=13
5x+6y=38
Answer:
(4, 3 )
Step-by-step explanation:
Given the 2 equations
x + 3y = 13 → (1)
5x + 6y = 38 → (2)
Multiplying (1) by - 2 and adding to (2) will eliminate the y- term
- 2x - 6y = - 26 → (3)
Add (2) and (3) term by term to eliminate y
3x + 0 = 12
3x = 12 ( divide both sides by 3 )
x = 4
Substitute x = 4 into either of the 2 equations and solve for y
Substituting into (1)
4 + 3y = 13 ( subtract 4 from both sides )
3y = 9 ( divide both sides by 3 )
y = 3
solution is (4, 3 )

Mr. and Mrs. Doran have a genetic history such that the probability that a child being born to them with a certain trait is 37%. If they have six children, what is the probability that at most one of their six children will have that trait? Round your answer to the nearest thousandth.
Answer:
Yes
Step-by-step explanation:
Answer:
Sum: 0.78619≈0.786
Step-by-step explanation:
n=4
r=1, 2, 3, 4
r=1,2,3,4
"At least" counts up.
p=32\%=0.32
p=32%=0.32
q=1-0.32=0.68
q=1−0.32=0.68
The chance a success does NOT occur.
_{n}C_{r}p^rq^{n-r}
The probability that at most one of their six children will have that trait is 0.68
How to determine the probability?From the question, the given parameters are
Number of children, n = 6
Probability of a child with the trait, p = 37%
The required probability that at most one will have that trait is represented as P(x ≤ 1)
This probability is calculated ;
P(x ≤ 1) = P(0) + P(1)
Where
P(x) = ⁿCₓ * pˣ (1 - p)ⁿ⁻ˣ
So, we have
P(x ≤ 1) = ⁷C₀ (37%)⁰ (1 - 37%)⁷⁻⁰ + ⁷C₁ (37%)¹ (1 - 37%)⁷⁻¹
Evaluate;
P(x ≤ 1) = ⁷C₀ * 1 * (63%)⁷ + ⁷C₁ * (37%) * (63%)⁶
So, we have;
P(x ≤ 1) = 1-0.32= 0.68
Hence, the probability is 0.68

Factorise by grouping: x² - 5x + 2x - 10
Answer:
[tex]\boxed {\boxed {\sf (x+2)(x-5)}}[/tex]
Step-by-step explanation:
To factor by grouping, first divide the polynomial into 2 groups with parentheses.
[tex]x^2-5x+2x-10[/tex]
[tex](x^2-5x)+ (2x-10)[/tex]
Factor the greatest common factor (GCF) out of both binomials.
For the first binomial, the GCF is x.
[tex]x(x-5) +(2x-10)[/tex]
For the second binomial, the GCF is 2.
[tex]x(x-5)+2(x-5)[/tex]
Factor out the common binomial which is (x-5).
[tex](x+2)(x-5)[/tex]
The factorized form of x²-5x+2x-10 is (x+2)(x-5)

Hunter is going to invest in an account paying an interest rate of 1.7% compounded continuously. How much would Hunter need to invest, to the nearest cent, for the value of the account to reach $4,500 in 18 years?
Answer:
$3333.33 approx
Step-by-step explanation:
Given data
Rate r= 1.7%
Final Amount A=$4500
Time = 18years
Principal P= ????
The expression for the compound interest is given bellow as
A=P(1+r)^t
4500= P(1+0.017)^18
4500= P(1.017)^18
4500= P*1.35
P= 4500/1.35
P= $3333.33
Hence the principal is $3333.33 approx

If I have 20 shares of a stock worth a total value of 440.80 what is the price per share of the stock?
If my total value dcreases by 6% what is it now?
Answer:
The price per share of the stock is 22.04. If the total value decreases by 6% the price becomes 20.71.
Step-by-step explanation:
440.80/20= 22.04
100-6= 94%
0.94 x 440.80= 414.35
414.35/20= 20.71

Omar is painting a 24-square-foot wall. The wall is divided into squares that each measure 14 square foot. How many squares is the wall divided into? Enter your answer in the box.
Complete question :
Omar is painting a 24-square-foot wall. The wall is divided into squares that each measure 1/4 square foot. How many squares is the wall divided into?
Answer:
96
Step-by-step explanation:
Given that:
Total area of wall = 24 ft²
Area of each division =. 1/4 ft²
Number of division = x
The number of divisions * area of each division = total area of wall
x * 1/4ft² = 24ft²
Divide both sides by 1/4 ft²
x = 24ft² ÷ 1/4 ft²
x = 24 * 4 /1
x = 96
Hence, wall is divided into 96 squares

Make r the subject - picture underneath
Answer:
The answer is r = 6a / (5m² - 1).
Step-by-step explanation:
The steps are :
[tex]m = \sqrt{ \frac{6a + r}{5r} } [/tex]
[tex] {m}^{2} = \frac{6a + r}{5r} [/tex]
[tex]5r {m}^{2} = 6a + r[/tex]
[tex]5r {m}^{2} - r = 6a[/tex]
[tex]r(5 {m}^{2} - 1) = 6a[/tex]
[tex]r = \frac{6a}{5 {m}^{2} - 1 } [/tex]
Answer:
r = [tex]\frac{6a}{5m^2-1}[/tex]
Step-by-step explanation:
Given
m = [tex]\sqrt{\frac{6a+r}{5r} }[/tex] ( square both sides )
m² = [tex]\frac{6a+r}{5r}[/tex] ( multiply both sides by 5r )
5rm² = 6a + r ( subtract r from both sides )
5rm² - r = 6a ← factor out r from each term on the left side
r(5m² - 1) = 6a ← divide both sides by (5m² - 1)
r = [tex]\frac{6a}{5m^2-1}[/tex]
