Answers
56/120
Step-by-step explanation:
The body masses of the two children in terms of their father's body mass, x, are:
First child's body mass = 5x/6 kg
Second child's body mass = 4x/5 kg
To express the body mass of the man's two children in terms of their father's body mass, we can use the given ratios.
Let the body mass of the man be x kg.
The first child's body mass is five-sixths of their father's body mass:
Body mass of the first child = (5/6) * x
= 5x/6 kg.
The second child's body mass is four-fifths of their father's body mass:
Body mass of the second child = (4/5) * x
= 4x/5 kg.
Therefore, the body masses of the two children in terms of their father's body mass, x, are:
First child's body mass = 5x/6 kg
Second child's body mass = 4x/5 kg

On average 12 customers arrive per hour. Let X be the number of customers arriving from 10 am to 10:30 am. What is P(6
Answers
To determine and graph the probability distribution function of the discrete random variable X with the given probability mass function p.
The probability distribution function (PDF) of a discrete random variable assigns probabilities to each possible value of the random variable. In this case, the probability mass function (PMF) p is already given, which specifies the probabilities for each value of X.
To graph the PDF, we plot the values of X on the x-axis and their corresponding probabilities on the y-axis. The graph will consist of discrete points representing the values and their probabilities according to the PMF.
To find the probability P(6< X ≤ 10) given that X follows a Poisson distribution with an average arrival rate of 12 customers per hour in the time interval from 10 am to 10:30 am.
The number of customers arriving in a given time period follows a Poisson distribution when the average arrival rate is known. In this case, the average arrival rate is 12 customers per hour, and we need to find the probability of having 6 < X ≤ 10 customers arriving between 10 am and 10:30 am.
To calculate this probability, we use the cumulative distribution function (CDF) of the Poisson distribution. The CDF gives the probability of observing a value less than or equal to a given value. Subtracting the CDF values for X = 6 and X = 10 will give us the desired probability.

Answers
Answer:
x=-2,y=-3
Step-by-step explanation:
x=7+3x
-3x+8y=-18
-21-y=-18
x=7+3x
y=-3
x=7+3x
x=-2
y=-3
Answer:
x = -2
y = -3
Step-by-step explanation:
There are three methods for solving system of equations: elimination, substitution, and graphing. In this case elimination would be the best method since you have -3x for both equations. When solving by elimination, your goal is to eliminate one of the variables, in this case we will eliminate x. Subtract the bottom equation from the top (it is important to remember here that the negative will distribute to the entire equation).
-3х + 9y = -21
- (- 3х +8y = -18)
_____________
y = -3
Now plug this y-value in to either equation and solve for x
-3х + 9y = -21
-3х + 9(-3) = -21
-3x - 27 = -21
-3x = 6
x = -2
Check your answer by plugging both values in to the second equation
- 3х +8y = -18
- 3(-2) +8(-3) = -18
6 - 24 = -18
-18 = -18

In AOPQ, m/O = (6x – 14)°, m/P = (2x + 16)°, and m/Q = (2x + 8)°.
Find m/Q.
Answers
The required measure of angle m∠Q is 42 degrees, as of the given condition.
What is the triangle?The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should equal to 180°
Here,
In a triangle, the sum of the angles is always equal to 180 degrees. Therefore, for triangle OPQ,
m∠O + m∠P + m∠Q = 180°
Using the given information,
m∠O = (6x - 14)°
m∠P = (2x + 16)°
m∠Q = (2x + 8)°
(6x - 14)° + (2x + 16)° + (2x + 8)° = 180°
10x + 10 = 180°
10x = 170
x = 17
Substituting the value of x back into the expression for m∠Q,
m∠Q = (2x + 8)°
m∠Q = (2 * 17 + 8)°
m∠Q = 42°
So the value of m∠Q is 42 degrees.

there are 8 bolt are US spec and 6 bolts are shorts , what is the
probability of selecting either a US spec or a short bolt? (hint:
P(US U Short)
Answers
The formula for the union of two events is:
P(US U S) = P(US) + P(S) - P(US ∩ S)
Given that there are 8 US spec bolts and 6 short bolts, we can calculate the individual probabilities:
P(US) = 8 / (8 + 6) = 8 / 14 = 4 / 7
P(S) = 6 / (8 + 6) = 6 / 14 = 3 / 7
Now, we need to determine the probability of the intersection of the two events, P(US ∩ S). Since a bolt cannot be both US spec and short, the intersection is empty, and therefore P(US ∩ S) = 0.
Plugging in the values, we can calculate the probability of selecting either a US spec or a short bolt:
P(US U S) = P(US) + P(S) - P(US ∩ S)
= 4/7 + 3/7 - 0
= 7/7
= 1
Therefore, the probability of selecting either a US spec or a short bolt is 1, which means it is guaranteed to happen since it includes all the bolts available.
Use the substitution
t = −x
to solve the given initial-value problem on the interval (−[infinity], 0).
4x2y'' + y = 0, y(−1) = 4, y'(−1) = 4
Answers
The solution of the initial-value problem is y(x) = 2e-x + 2eⁿx.
The given differential equation is 4x²y'' + y = 0.
The substitution is t = -x.
Thus, x = -t, and therefore dx/dt = -1.
Solve for y' and y'' in terms of t instead of x. Using the chain rule,
y' = dy/dx × dx/dt = dy/dt × (-1) = -y'.y'' = d²y/dx² × (dx/dt)² + dy/dx × d²x/dt² = d²y/dt² + y′.
We have to replace y'' and y' in the differential equation and simplify it.
4x²y'' + y = 0 becomes 4t²(y'' - y') + y = 0.
We now have a first-order homogeneous linear differential equation. The characteristic equation of the differential equation is r² - 1 = 0.
Solving the characteristic equation, we get r = ±1.
Therefore, the general solution is y(t) = c₁et + c₂e-t.
This solution is for the interval (-[infinity], infinity). We need to solve for the given initial conditions to find the particular solution.
Using the first initial condition, we get4 = y(-1) = c₁e-1 - c₂e1 ⇒ c₁e-1 - c₂e1 = 4.
Using the second initial condition, we get-4 = y'(-1) = -c₁e-1 - c₂e1 ⇒ c₁e-1 + c₂e1 = 4.
The system of linear equations is given by[c₁e-1, -c₂e1] × [1, 1; -1, 1] = [4, -4]
Solving for c₁ and c₂, we getc₁ = 2e, c₂ = 2e-1.
The particular solution is
y(t) = 2eet + 2e-t.
Using the substitution x = -t, we gety(x) = 2e-x + 2eⁿx.
The solution of the initial-value problem is y(x) = 2e-x + 2eⁿx.

Mary has 7 1/4 yards of fabric. She cuts off foot of fabric to make the edge even. Mary wants to end up with 3 pieces of fabric that are the same size. How long will each piece be? (1 yard = 3 feet)
Answers
each piece will be 2 1/3 yards
Explanation:Total fabric Mary has = 7 1/4 yards
She cuts off = 3/4 ft
First we need to convert from foot to yard the part cut off. Then we subtract the part that was cut off from the total fabric.
\(\begin{gathered} Given\colon\text{ 1 yard = 3 fe}et \\ 3feet\text{ = 1 yard} \\ \frac{3}{4\text{ }}ft\text{ = x} \\ x(3)\text{ = }\frac{3}{4}\text{ }\times\text{1} \\ 3x\text{ = }\frac{3}{4} \\ x\text{ = }\frac{3}{4}\div3=\frac{3}{4}\times\frac{1}{3} \\ x\text{ = 1/4 yard} \\ \text{Hence, 1/4 yard was cut off} \end{gathered}\)Subtracting the part cut off:
\(7\text{ }\frac{1}{4}yard\text{ - }\frac{1}{4\text{ }}\text{yard = 7 yard}\)We are informed Mary want 3 pieces of the fabric of same size after the fraction has been cut off.
we divide 7yards into 3:
\(\begin{gathered} \text{Each piece of fabric left = }\frac{7\text{ yards}}{3} \\ \text{Each piece of fabric left = 2}\frac{1}{3}\text{ yards} \end{gathered}\)Hence, each piece will be 2 1/3 yards

how do you solve (7x + 5) - (3x + 2)
Answers
Answer:
x = 0.75
Step-by-step explanation:
Simplifying
(7x + -5) + -1(3x + -2) = 0
Reorder the terms:
(-5 + 7x) + -1(3x + -2) = 0
Remove parenthesis around (-5 + 7x)
-5 + 7x + -1(3x + -2) = 0
Reorder the terms:
-5 + 7x + -1(-2 + 3x) = 0
-5 + 7x + (-2 * -1 + 3x * -1) = 0
-5 + 7x + (2 + -3x) = 0
Reorder the terms:
-5 + 2 + 7x + -3x = 0
Combine like terms: -5 + 2 = -3
-3 + 7x + -3x = 0
Combine like terms: 7x + -3x = 4x
-3 + 4x = 0
Solving
-3 + 4x = 0
