To find (f-g)(1), we first need to find f(1) and g(1): f(1) = -(1)^2 - 1 - 3 = -5 g(1) = -1 Now we can substitute these values into (f-g)(x) = f(x) - g(x) and simplify: (f-g)(1) = f(1) - g(1) = (-5) - (-1) = -4 Therefore, (f-g)(1) = -4.

Explain about the fraction of number:The fractional bar is a horizontal bar that divides the numerator and denominator of every fraction into these two halves.
The number of parts by which the whole has already been divided is shown by the denominator. It is positioned in the fraction's lower portion, just below fractional bar.How several sections of both the fraction are displayed or chosen is shown in the numerator. It is positioned well above fractional bar in the upper portion of the fraction.Given data:
Total rows of seats = 22Number of seats in each row = 4Filled rows = 191/2 of the remaining.Total seats in bus = Total rows of seats * Number of seats in each row
Total seats in bus = 22 * 4
Total seats in bus = 88
Filled seats = 19 * 4 = 76
Left seats = 88 - 76 = 12

Tom and John are engaged in buying and selling certain products A and B. Tom BUYS 5 of product A but
SELLS twice as much of product B. John on the other hand SELLS three times what Tom BOUGHT of
product A and BUYS 13 of product B. At the end of the business day, John banks Ksh 110,000/- while
Tom banks Ksh 230,000.
Under the assumption that the sale prices for product A and B are the same for the two men, and the costs prices for the products A and B are also the same for the two men, obtain the following:
The price for product A which was determined as Ksh 42,727.27 and the price for product B as 44,363.63
Question: If there was a mark up of 25% on the cost price and a discount of 15% on the sale price, how
much would each of the partners have banked at the end of the business day?
Product A is priced at Ksh 55,000, while Product B is priced at Ksh 32,000.
How to calculate Product A and B?Assume that the selling price for both the two items A and B is "S" and the cost price for both is "C". Using this knowledge, we can create two equations that relate the costs and revenues of the two items, one for Tom and one for John:
Tom: 5C - 2(5S) = [tex]P_1[/tex]
John: 3(5C) - 13C = [tex]P_2[/tex]
where [tex]P_1[/tex] and [tex]P_2[/tex] represent Tom's and John's respective profits.
We are aware that John deposits Ksh. 110,000 while Tom deposits Ksh. 230,000 at the end of the business day. Thus, we can say:
[tex]P_1[/tex] = 230,000 - 5C
[tex]P_2[/tex] = 110,000 - 18C
These values are what we obtain when we enter them into the equations for Tom and John:
5C - 2(5S) = 230.000 - 5C
When we simplify these equations, we obtain:
10C - 10S = 230,000
2C = 110,000
Solving for C, we get:
C = 55,000
We may determine S by adding this value back into the original equation:
10(55,000) - 10S = 230,000
Simplifying this equation, we get:
S = 32,000
Therefore, the price for product A is Ksh 55,000 and the price for product B is Ksh 32,000.

Are conditional probabilities always dependent?
Answer:
Two events are said to be independent if one event occurring does not affect the probability that the other event will occur. However, if one event occurring or not does, in fact, affect the probability that the other event will occur, the two events are said to be dependent.
If one event occurs or not, it does, in fact, affect the probability that the other event will occur, and then the two events are said to be dependent.
Mary Lou Mason purchased baby bottles for $4.56, baby formula for $12.45, and a pacifier for $2.13. For all purchases she must pay the state sales tax of 6.5 percent and the county tax of 1.5 percent. What is the tax on her purchases? Show all of your work.
Answer:
$1.53
Step-by-step explanation:
You want to know the total tax on purchases of $4.56, 12.45, and 2.13 if the tax rate is the sum of 6.5% and 1.5%.
TaxThe tax is the product of the tax rate and the total of purchases. The tax rate will be the sum of the state and county tax rates:
6.5% +1.5% = 8% = 8/100
The attached calculation shows the tax is $1.53 after rounding to cents.
The tax rate on Mary Lou Mason's purchases is $1.53.
What is meant by rate?
In mathematics, rate usually refers to the ratio of two quantities that have different units of measurement.
To calculate the total tax on Mary Lou Mason's purchases, we need to first calculate the total cost of her purchases, including both the prices of the items and the sales tax.
The total cost of Mary Lou Mason's purchases before taxes is:
$4.56 + $12.45 + $2.13 = $19.14
To calculate the sales tax, we need to multiply the total cost of the purchases by the sum of the state and county tax rates:
6.5% + 1.5% = 8%
So the sales tax rate is 8%.
To calculate the total tax on Mary Lou Mason's purchases, we multiply the total cost of the purchases by the sales tax rate:
$19.14 x 8% = $1.53
Therefore, the tax on Mary Lou Mason's purchases is $1.53.

1. State the converse, contrapositive, and inverse of the conditional statement “A positive integer is a prime only if it has no divisors other than 1 and itself”.
Answer:
Step-by-step explanation:
A contrapositive statement changes "if not p then not q" to "if not q to then, not p." The converse of the conditional statement is “If Q then P.” The contrapositive of the conditional statement is “If not Q then not P.” The inverse of the conditional statement is “If not P then not Q.” if p → q, p → q, then, ∼ q →∼ p ∼ q →∼ p

Sneeze: According to a study done by Nick Wilson of Otago University Wellington, the probability a

Task 1: What is and what is ?
Task 2: What are the mean and standard deviation?
Task 3: What are the conditions that must be met to use the normal approximation to the binomial
distribution? Are they met?
Thus, the mean and standard deviation for the randomly selected individuals is found as: mean = 80.1 and standard derivation = 7.66.
Explain about the standard deviation:The standard deviation is a measurement of how widely spaced out a set of data is from the mean. The bigger the dispersion or variability, the higher the standard deviation and the greater the magnitude of the value's divergence from its mean. It represents the absolute variability of a distribution.
Given data:
Number of population n = 300
probability p = 0.267
Mean is given as np:
np = 300*0.267
np = 80.1
standard derivation: √np(1 - p)
√np(1 - p) = √80.1(1 - 0.267)
√np(1 - p) = √58.7133
√np(1 - p) = 7.66
Thus, the mean and standard deviation for the randomly selected individuals is found as: mean = 80.1 and standard derivation = 7.66.

5x + 3y = 8
Answer:
x = -2, y = 6
Step-by-step explanation:
First, find the opposite of 10 by multiplying 5x+3y=8 by -2 to eliminate 10x.
10x+10y=40
-2(5x+3y=8)
10x+10y=40
-10x-6y=-16 (Subtract 10y - 6y) (Subtract 40 - 16)
4y = 24 (Divide by 4 on both sides)
y = 6
Substitute 6 in the y value in any of the equations.
10x+10(6)=40 (Replaced 10y with 10(6) )
10x+60=40
-60 = -60 (Subtract 60 from both sides)

Below 10 in.*6 in.*14 in., the triangular prism's volume is 420 cubic inches.
The area of the base must be multiplied by the prism's height in order to determine the volume of a triangular prism.
The base of this triangular prism is a triangle with a base of 6 inches and a height of 10 inches, so its area is:
Area of base = (1/2) × base × height = (1/2) × 6 in × 10 in = 30 in²

In a class of 20 children, 8 had one sister, 6 had 2 sisters. The mean number of children was 1. how many children had no sisters
There are no children in the class who have no sisters. This is because the mean number of children is 1, and some children have more than one sibling to Balance out those who have only one.
To solve this problem, we need to use some basic principles of statistics and probability. Let's start by identifying the key information provided in the problem. We know that there are 20 children in the class, and that some of them have sisters. Specifically, 8 children have one sister and 6 children have two sisters. We also know that the mean (average) number of children is 1, which means that on average, each child has one sibling.
To find out how many children had no sisters, we can use the following formula:
Total number of children - (number of children with one sister x 1) - (number of children with two sisters x 2) = number of children with no sisters
Using the values from the problem, we get:
20 - (8 x 1) - (6 x 2) = 0
This means that there are no children in the class who have no sisters. While this may seem counterintuitive, it's important to remember that the mean number of children is 1, which means that some children must have more than one sibling in order to balance out the others who have only one.
In summary, the answer to the question is that there are no children in the class who have no sisters. This is because the mean number of children is 1, and some children have more than one sibling to balance out those who have only one.
