Answer:
Part A: x+y=75 is the 1st linear equation
y=25+x
Part B:
x+y=75
x+(25+x)=75
2x=50
x=25
she spends 25 mins running
part c : no because if she spends 45 mins
then x+y=70
but x+y=75
she spends 50 mins dancing
Solve the system of equations 4x+3y=6
Answer:
you do not have the second system of the equation for this so we'd solve it just like we solve standard form
x = 1.5
y = 2
Step-by-step explanation:
Solve for x
0.5(5−7x)=8−(4x+6)
x = ???

Evaluate the expression 16!/12!4!
Answer: Sorry i don't really understand the question
Step-by-step explanation:
Some parts of California are particularl earthquake prone. Suppose in one metropolitan area, 40% of all homeowners are insured against earthquake damage. Four homeowners are selected at random. Let X denote the number among the four who have earthquake insurance. Assume that the event of each homeowner having or not having insurance is independent.
Required:
a. Find the probability mass function of X?
b. What is the most likely value for X?
c. What is the probability that at least two of the four selected have earthquake insurance?
Answer:
Kindly check explanation
Step-by-step explanation:
Given that:
Percentage of insured home owners = 40% p = 0.4
Selecting 4 home owners (x) ;
x = 0, 1, 2, 3, 4
Using bernoulli;
nCx * p^x * (1 - p)^(n-x)
For X = 0
4C0 * 0.4^0 * 0.6^(4-0) = 0.1296
X = 1
4C1 * 0.4^1 * 0.6^(4-1) = 0.3456
X = 2
4C2 * 0.4^2 * 0.6^(4-2) = 0.3456
X = 3
4C3 * 0.4^3 * 0.6^(4-3) = 0.1536
X = 4
4C4 * 0.4^4 * 0.6^(4-4) = 0.0256
B.) The most likely value for X are 1 and 2 with probabilities of 0.3456 respectively.
C.) probability that atleast 2 of the 4 selected have earthquake insurance ;
P(X ≥ 2) = p(2) + p(3) + p(4)
P(X ≥ 2) = 0.3456 + 0.1536 + 0.0256
P(X ≥ 2) = 0.5248

10. The expression 4 (2x-5)+7(x+2) can be written in simplest form as
(1) 11x-10
(3) 15x - 6
(2) 13x -3
(4) 16x + 7
Answer:
15x-6
Step-by-step explanation: 4 * 2x = 8x
4*-5 = -20
7*x = 7x
7*2= 14
Combine like terms 8x + 7x + 14-20
15x-6

Write the equation in point-slope form of a line that has a slope of m=2 and the point (x, y) = (6,8).
(Remember: point-slope form is y-y1 = m(x -x1)
where (x1, y1) is a point and m is the slope.)
Answer:
y-8 = 2 (x-6)

Write a paragraph describing the business venture and what kind of algebra or other calculations and formulas might help someone in that endeavor. Also include ways in which the business might operate differently with those tools than without them.
Step-by-step explanation:
A business that offers services to people by providing many amusement and fun with gate fees
The algebraic equations to be used is the general linear equation
Y = MX + C
Where
Y = total income or money realised
M = rate or price rate
X = number of goods or services
C = flat rate or gate fees
The business can also operate differently by using exponential equation
A = P(1 + R%)^t
Where
A = profit
P = capital
R = rate
t = time

How do you do this question?
Answer:
81 / 40
Step-by-step explanation:
The Maclaurin expansion of sin x is:
sin x = ∑ₙ₌₀°° (-1)ⁿ x²ⁿ⁺¹ / (2n+1)!
sin x = x − x³/3! + x⁵/5! − x⁷/7! + ...
Substituting this into the limit:
lim(x→0) [sin(3x) − 3x + ⁹/₂ x³] / x⁵
lim(x→0) [(3x − (3x)³/3! + (3x)⁵/5! − (3x)⁷/7! + ...) − 3x + ⁹/₂ x³] / x⁵
lim(x→0) [(3x − ⁹/₂ x³ + 3⁵x⁵/5! − 3⁷x⁷/7! + ...) − 3x + ⁹/₂ x³] / x⁵
lim(x→0) (3⁵x⁵/5! − 3⁷x⁷/7! + ...) / x⁵
lim(x→0) (3⁵/5! − 3⁷x²/7! + ...)
3⁵/5!
243 / 120
81 / 40
