Answer:
x=(-3,0)
y intercept= (0,-1)
Step-by-step explanation:
to find the x-intercept you need to substitute 0 for y and solve for x. To find the y intercept, substitute 0 for x and solve for y.

Airlines A and B each operate one flight per day between the cities of Hartford and Chicago; the daily passenger volume between the two cities is 350. Because the quality of service and departure times for both airlines are similar, we assume that passengersselect the flights with equal probability and independently of one another.
Required:
a. Let X denote the number of passengers on the flight operated by airline A. Describe the exact distribution of X; name it and identify the parameters.
b. If the plane for airline A carries 210 seats there is a positive probability that more than 210 passengers will turn up, in which case not all passengers can be accommodated. Estimate the probability of "overbooking"
c. Denote by n the minimum number of seats the aircraft should contain if it is desired that the probability of exceeding the seating capacity be less than 0.01. Find n
Answer:
X ~ (350, 0.5)
0.00009
Step-by-step explanation:
Given that:
Daily passenger volume = 350
Since both airlines A and B have equal probability ;
p = 0.5
n = 350
X ~ (n, p)
X ~ (350, 0.5)
B.)
Mean, m= np = 350 * 0.5 = 175
Standard deviation, s = sqrt(np(1-p)) = sqrt(350*0.5*0.5) = sqrt(87.5)
Obtaining standardized score, Z
Z = (x - m) / s
x = 210
Z = (210 - 175) / sqrt(87.5)
Z = 35 / sqrt(87.5)
Z = 3.74
P(Z > 3.74) = 0.00009 (Z probability calculator)

Ryan earns $5 for each small dog he walks and $8 for each large dog he walks. Today he walked 8 dogs and made a total of $49. How many small dogs did Ryan walk?
Ryan walked
small dogs.
Answer:
small dogs= 5
large dogs= 3
Step-by-step explanation:
Step one:
given data
let the number of small dogs be x
and the number of large dogs be y
Ryan earns $5 for each small dog he walks and $8 for each large dog he walks.
He walked 8 dogs and made a total of $49
so
5x+8y=49----------1
x+y=8---------------2
x=8-y
5(8-y)+8y=49
40-5y+8y=49
collect like terms
3y= 49-40
3y=9
divide both sides by 3
y=9/3
y=3
put y= 3 in eqn 2
x+3=8
x=8-3
x=5
If line p has a slope of -1/2, what is the slope of a line ;
perpendicular to p? parallel to p?
Answer:
Parallel: -1/2
Perpendicular: 2
Step-by-step explanation:
The slope of a line parallel to another, always has the same slope as the line that it is parallel to.
The slope of a line perpendicular to another, always has the opposite reciprical to the line that it is perpendicular to.

B
Step-by-step explanation:
A tank that is 30% full contains 651 gallons of water. How much water does the tank hold when it is full?
Question 1 options:
1,620 gallons
2,160 gallons
1,627.5 gallons
2,170 gallons
last one 2170
Answer:
651=30 percent
x=100 percent
x=( 100×651)/30=2170 gallons
Answer:
2,170 gallons
Step-by-step explanation:
First you can see that at 30% we have 651 gallons so you want to multiply it by three because we are trying to get to 100% after you multiply it by three we have found out how much it is filled at 90% which is 1953 so then you want to divide 651 by 3 because all we need is 10 more percent to make it to 100% and 1/3 of 30% is 10% and 10% of 651 is 217. Finally all you have to do is add 217 and 1953 and you get 2,170 gallons.
Hope this helps!
It can be helpful to classify a differential equation, so that we can predict the techniques that might help us to find a function which solves the equation. Two classifications are the order of the equation -- (what is the highest number of derivatives involved) and whether or not the equation is linear . Linearity is important because the structure of the the family of solutions to a linear equation is fairly simple. Linear equations can usually be solved completely and explicitly. Determine whether or not each equation is linear:
Answer:
The equations are not given but the clue to your answer is given below:
Step-by-step explanation:
So the question above talks generally about differential equations (equations whose derivatives can be found) and then describes them thus - the order of a differential equation and the linearity status of a differential equation.
To determine whether or not each of the absent equations is linear, check for the following characteristics of linearity:
1. The maximum number or power that any variable in a linear equation is raised to is 1.
Example: 2x² + 6y = 43y is NOT a linear equation because some or all (in this case, variable x) of the variables in it are raised to a power greater than 1. Variable x is raised to the power of 2.
2. An equation (a linear equation, in this case) contains an 'equal to' sign. This is the reason why it's called an equation. There is a mathematical expression on each side of the equal to sign. Take note of this, just incase one of the options in your question has no equal to sign.
Example: 2x + 6y is NOT a linear equation. It is a linear expression. It contains no equal to sign that compares two distinct mathematical expressions.
3. A linear equation usually has not more than two variables. It is not complex or difficult to solve.
Example: 2x + 6y = 43z is NOT a linear equation.

Answer:
4x + 8
Step-by-step explanation:
1. 4(2x + 4) Multiply 2x by 4 to get 8x. Multiply 4 by 4 to get 16. You should now have the equation 8x + 16 / 2.
2. Divide the 8x and 16 by 2. You should get 4x and 8. (4x + 8).

If John and Peter share some money in the ratio 3:4, what fraction of the money does John receive?
Answer:
So 3/7 is the fraction of the money John received.
Step-by-step explanation:
3:4, so John is 3 and Peter is 4.
Now add these up for the denominator which is 3+4=7
and put Johns value over it, Johns value is 3.
So 3/7 is the fraction of the money John received.
HELP ME PLEASE!!! this dosent make sense
Answer:
I think it would be D not sure tho hope this is helpful
Answer:
B
Step-by-step explanation:
The correct answer is B because in A and C, the gray area is not under the blue line since y has to be less than the equation. It is not D because the equation does not have a negative slope and in this inequality, it is also not equal to. Because the line in D is not a dotted line, then you know it is also equal to.

Write an example of the Commutative Property of Multiplication.
help pleassssssseeee
Answer:
Commutative property: When two numbers are multiplied together, the product is the same regardless of the order of the multiplicands. For example 4 * 2 = 2 * 4 Associative Property: When three or more numbers are multiplied, the product is the same regardless of the grouping of the factors. For example (2 * 3) * 4 = 2 * (3 * 4)

Given 3 is a leg of a right triangle and 13 is the hypotenuse, what is the length of the other leg of the right triangle? Round
your answer to the nearest hundredth (2 decimal places)
Answer:
12.64 (unrounded)
Step-by-step explanation:
formula; a^2+b^2=c^2
you have your given which is 3 and hypotenuse of 13
plug in 3^2+b^2=13^2
solve 9+b^2=169
subtract 9 to the right side
169-9=160
bring down b^2=160
get rid of the square so [tex]\sqrt{160}[/tex]
which will be 12.64 unrounded
