Convert 19/5 to a mixed number.
Answers
Answer:
3 4/5
Step-by-step explanation:
First lets ask ourselves how many times 5 can go into 19, that would be 3 and we would be left with a remainder of 4.
So next we would put 3 as a whole number and our 4 as a fraction over 5.
That leaves us with the mixed number 3 4/5.

2/3a =b+4f solve for a
Answers
Answer:Simplifying
4f = 30 + -1f
Solving
4f = 30 + -1f
Solving for variable 'f'.
Move all terms containing f to the left, all other terms to the right.
Add 'f' to each side of the equation.
4f + f = 30 + -1f + f
Combine like terms: 4f + f = 5f
5f = 30 + -1f + f
Combine like terms: -1f + f = 0
5f = 30 + 0
5f = 30
Divide each side by '5'.
f = 6
6
Step-by-step explanation:
the solution to the equation 2/3a=b+4f is: a = 6f + 3b. To solve for a in the equation 2/3a=b+4f, we can do the following steps.
Subtract b from both sides of the equation. This gives us:
2/3a - b = 4f
Multiply both sides of the equation by 3/2. This gives us:
a - 3b = 6f
Add 3b to both sides of the equation. This gives us:
a = 6f + 3b
Therefore, the solution to the equation 2/3a=b+4f is:
a = 6f + 3b

45 for an old guitar he cleaned up the guitar then resold it after marking up the price 15% used 36 of the money he got for the guitar to buy books how much money did Ben's been on books
Answers
Ben spent $36 on books after he sold his guitar for $51 and used $15 of it for some other purpose.
If we add a markup of 15% to $45, we get:
Markup = 15% of 45
Markup = 0.15 × 45 = $6
The selling price of the guitar becomes:Sale price = Cost price + Markup
Sale price = $45 + $6
Sale price = $51
Ben sold the guitar for $51.
He used $36 of that money to buy books.
To find out how much he spent on books, we need to subtract the cost of books from the sale price of the guitar. $51 − $36 = $15.
Ben spent $36 on books.
Thus, Ben spent $36 on books after he sold his guitar for $51 and used $15 of it for some other purpose.

Answers
Univariate and multivariate analysis are broader terms that refer to the analysis of single variables and multiple variables, respectively, and may not specifically address the issue of percentiles of ranked data.
To determine the confidence intervals of percentiles of ranked data, it is most appropriately assessed using nonparametric testing. Nonparametric testing is a statistical method that does not rely on assumptions about the distribution of the data. It is particularly useful when dealing with ranked data, as it does not require the data to follow a specific distribution.
This method allows for the estimation of percentiles and confidence intervals without making assumptions about the underlying distribution. Parametric testing, on the other hand, assumes that the data follows a specific distribution and may not be appropriate for ranked data.

find the solution to the differential equation with the given initial condition
Answers
The solution of the differential equation dy/dx = x/y with the given initial condition y(0) = -2 is found to be y = √(x²+4).
The differential equation that we have to solve is given to be, dy/dx = x/y.
Now, the initial condition is y(0) = -2, it means on putting x = 0 in the final answer we get y = -2. So,
dy/dx = x/y
ydy = xdx
Now, integrating both sides of the equation, ydy = xdx,
∫ydy = ∫xdx
y²/2 = x²/2 + C
y = √(x²+2C)
C is the constant of integration, Putting x = 0,
-2 = √2C
Squaring both sides,
4 = 2C
C = 2, now putting the value of C in the solution,
y = √(x²+2(2))
So, the final solution of the differential equation is y = √(x²+4).

(ii) Another pair of polar coordinates for the point (2, -π/7) such that r < 0 and -2π ≤ θ < 0 is (-2, -15π/7).
(a) To find another pair of polar coordinates for the given point (2, -π/7) such that r > 0 and 2π ≤ θ ≤ 4π, we can add any multiple of 2π to the angle while keeping the radius positive. Let's start by finding the equivalent angle within the given range.
Given θ = -π/7, we can add 2π to it to get a new angle within the desired range:
θ' = -π/7 + 2π = 13π/7
So, for r > 0 and 2π ≤ θ ≤ 4π, the polar coordinates are (2, 13π/7).
(ii) To find another pair of polar coordinates for the given point (2, -π/7) such that r < 0 and -2π ≤ θ < 0, we can keep the radius negative and add any multiple of 2π to the angle.
Given θ = -π/7, we can add -2π to it to get a new angle within the desired range:
θ' = -π/7 - 2π = -15π/7
So, for r < 0 and -2π ≤ θ < 0, the polar coordinates are (-2, -15π/7).

a fair coin is tossed four times. what is the probability that heads (h) will appear at least twice?
Answers
Answer: 11/16
Step-by-step: Whenever dealing with a problem like this. Times how many times its being tossed: 4x2 Then times that by two again: 4x2x2.
The probability of getting heads at least twice when tossing a fair coin four times is 6/16 or 0.375, and this can be calculated using either the counting method or the binomial probability formula.
The probability of getting heads or tails on a single coin toss is always 1/2 or 0.5. In order to determine the probability of getting heads at least twice when tossing a fair coin four times, we need to consider all the possible outcomes.
There are a total of 16 possible outcomes when tossing a fair coin four times, as each coin toss can result in either heads (H) or tails (T). These outcomes are:
HHHH
HHHT
HHTH
HHTT
HTHH
HTHT
HTTH
HTTT
THHH
THHT
THTH
THTT
TTHH
TTHT
TTTH
TTTT
Out of these 16 possible outcomes, there are 6 outcomes in which heads appear at least twice:
HHHH
HHHT
HHTH
HHTT
HTHH
THHH
Therefore, the probability of getting heads at least twice when tossing a fair coin four times is 6/16 or 0.375.
Another way to calculate this probability is by using the binomial probability formula:
P(X≥2) = 1 - P(X<2)
P(X<2) = P(X=0) + P(X=1)
Where X is the number of heads that appear in four coin tosses.
P(X=0) = (1/2)^4 = 1/16
P(X=1) = 4(1/2)^4 = 4/16
Therefore, P(X<2) = 1/16 + 4/16 = 5/16
And P(X≥2) = 1 - 5/16 = 11/16 or 0.375.
In conclusion, the probability of getting heads at least twice when tossing a fair coin four times is 6/16 or 0.375, and this can be calculated using either the counting method or the binomial probability formula.

Given information: Anna is in charge of the alumni fundraiser for her alma mater. She is selling pre-sale tickets for $10 and at-the-door tickets $25. The venue has the capacity to hold 400 people.
The graph represents the number of tickets Anna needs to sell to offset her upfront costs and raise at least $5,000 for her school.
The minimum number of at-the-door tickets she needs to sell to make her goal can be calculated as follows;
Let's suppose that x represents the number of pre-sale tickets, and y represents the number of at-the-door tickets Anna needs to sell.
Then the following equation represents the total amount of money Anna will earn after selling the given number of tickets;
10x + 25y ≥ 5,000
If she sells all the tickets, she will have sold a total of x + y tickets. But, we know that the venue has a capacity of 400 people.
So, we also know that;
x + y ≤ 400
Solving the two equations for y gives;
10x + 25y ≥ 5,00025y ≥ 5,000 - 10x y ≥ (5,000 - 10x)/25y ≥ 200 - 0.4xy ≤ 333.3 - 0.4x
