Answer:
Total bill = 7 pounds .
Step-by-step explanation:
Given : You buy 3.17 pounds of apples, 1.25 pounds of pears, and 2.56 pounds of oranges.
To find : What is your total bill rounded to the nearest cent.
Solution : We have given
Apple = 3.17 pounds
Peas = 1.25 pounds
Orange = 2.56 pounds.
Total bill = 3.17 + 1.25 +2.56 = 6.98
Total bill = 6 .98 pounds .
We can see number after decimal is greater than 5 so number would be increased b 1.
Total bill = 7 pounds .
Therefore, Total bill = 7 pounds .
Without knowing the price per pound of the fruit, it's impossible to calculate the total bill. However, if you knew the individual prices, like in the example, you could add up these amounts together to find the total cost.
Explanation:The question you're asking appears to be missing some important information. Specifically, we would need to know the price per pound of the apples, pears, and oranges in order to calculate your total bill. However, let's use an analogous example. Suppose you buy 10 apples at 50 cents each, 12 bananas at 20 cents each, and 2 bunches of grapes at 65 cents each. Your total cost would be $5.00 for apples, $2.40 for bananas, and $1.30 for grape. Altogether, this comes to $8.70.

what is 22119 rounded to the nearest hundredth
Answer:
22119 to the nearest hundred is 22100
Step-by-step explanation:
When rounding the number to the nearest hundred. Follow the given rules:
When rounding to the nearest hundred, look at the TENS DIGIT of the number.
If that digit is 0, 1, 2, 3, or 4, you will round down to the previous hundred.In other words if the number at the tenth position is less than 5 then we will convert all the digits after the hundred to zeros
If that digit is 5, 6, 7, 8, or 9, you will round up to the next hundred.In other words if the number at the tenth position is greater than or equals to 5 then we will add one to the hundred and convert all digits after the hundred to zeros.Now look at the given number which is: 22119
The number at the hundredth position is 1.
And the number at the tenth position is also 1.
Then according to the defined rule if the number at the tenth position is less than 5 then we will convert all the digits after the hundred to zeros.
So, for the given number (22119) we just convert all digits after the hundred to zeros
Therefore, 22119 to the nearest hundred is 22100...
in your own words explain the steps you would need to take to find slope from data in a table
Answer:
see the explanation
Step-by-step explanation:
we know that
To calculate the slope we need to take two points from data in a table
point 1 (x1,y1) and point 2(x2,y2)
The formula to calculate the slope between two points is equal to
[tex]m=\frac{y2-y1}{x2-x1}[/tex]
substitute the values and solve for m
The slope formula can be applied to find the slope from data in a table using any two set of points given on the table.
First, select any two pair of points given in the table. For example, let's assume the two set of points selected are:
[tex](a, b) $ and $ (c, d)[/tex]
Use the slope formula which is:
[tex]Slope(m) = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
The slope is the change of y over the change of x.
To use the slope formula:
Let,
[tex](a, b) = (x_1, y_1)\\(c, d) = (x_2, y_2)[/tex]
Then, plug in the values into the formula and solve.
The value you get is the slope of the data represented by the table.

In a survey of university students, 64 had taken mathematics course, 94 had taken chemistry course, 58 had taken physics course, 28 had taken mathematics and physics, 26 had taken mathematics and chemistry, 22 had taken chemistry and physics course, and 14 had taken all the three courses. find how many had taken one course only.
Final answer:
To find the number of students who took only one course among mathematics, chemistry, or physics at a university, we use the principle of inclusion and exclusion. After calculating, we find that 154 students had taken exactly one course.
Explanation:
To determine how many university students had taken only one course among mathematics, chemistry, and physics, we can use the principle of inclusion and exclusion. From the information given, we know the following:
Students who took mathematics (M): 64
Students who took chemistry (C): 94
Students who took physics (P): 58
Students who took both mathematics and physics (M∩P): 28
Students who took both mathematics and chemistry (M∩C): 26
Students who took both chemistry and physics (C∩P): 22
Students who took all three courses (M∩C∩P): 14
Let's define S as the number of students who took only a single course. We can calculate S using the formula:
S = (M + C + P) - (M∩P + M∩C + C∩P) + M∩C∩P
Substituting the values we get:
S = (64 + 94 + 58) - (28 + 26 + 22) + 14
S = 216 - 76 + 14
S = 140 + 14
S = 154
Therefore, 154 students had taken only one course.

what is the interval notation for -3<x<4
The inequality is , -3<x<4. Thus, the correct interval notation for the given inequality is (-3, 4),
The question concerns how to express the inequality -3<x<4 in interval notation. Interval notation is a way to denote a range of numbers on the real line where certain numbers are included or excluded in the set.
The notation uses brackets and parentheses to indicate closed or open intervals, respectively. A closed interval means the endpoint is included, while an open interval means the endpoint is not part of the set.
In this instance, the inequality suggests that x can take any value between -3 and 4, but cannot equal -3 or 4.
Thus, we use parentheses to denote that both -3 and 4 are not contained within the interval.
Therefore, the correct interval notation for the given inequality is (-3, 4), where the round parentheses indicate that -3 and 4 are not included in the solution set.

Final answer:
To calculate the commission, multiply the commission rate by the sale price.
Explanation:
To calculate the commission she will receive from the sale, we can use the expression: commission = (commission rate) * (sale price).
In this case, the commission rate is 18 percent, which can be written as 0.18 in decimal form.
Therefore, the expression for the commission is: commission = 0.18 * $569 = $102.42.
So, the salesperson will receive approximately $102.42 in commission from the sale.

The number of arrangements is: [tex]\(\frac{{50!}}{{18!12!8!12!}}\)[/tex]
To calculate the number of different arrangements of the beads, we can use the formula for permutations of multiset:
[tex]\(\frac{{n!}}{{n_1!n_2!n_3!n_4!}}\)[/tex]
where:
n is the total number of items to arrange,
n_1, n_2, n_3, n_4 are the numbers of indistinguishable items of each type.
For our beads, we have:
Total beads n = 18 (red) + 12 (yellow) + 8 (blue) + 12 (black) = 50 beads,
n_1 = 18 (red),
n_2 = 12 (yellow),
n_3 = 8 (blue),
n_4 = 12 (black).
So, the number of arrangements is: [tex]\(\frac{{50!}}{{18!12!8!12!}}\)[/tex]
This value gives us the total number of different color arrangements possible when stringing these beads in a row.
Given three collinear points, which of the following is true?a.. There is exactly one plane that contains all three points. b..They form a triangle. c.They are not coplanar. d.They are contained in multiple planes.
Option: d is the correct answer
d. They are contained in multiple planes.
Step-by-step explanation:Since, the three points are collinear.
This means that there is a line which pass through these three given points and as we know that a line always lie in a plane so all the three points will be coplanar and there may be multiple planes which contain a line.
Also, a triangle is formed with the help of three non-collinear points.

find the equation of the passing through p(4,6) which is parallel to the line with equation 4x-2y+6=0
The equation for the line passing through point P(4,6) that is parallel to the given line 4x - 2y + 6 = 0 is y = 2x - 2.
Explanation:The subject of the question is climbing up a function of mathematics known as linear algebra. The equation of the original line given is 4x - 2y + 6 = 0. First, you need to rearrange the equation to the slope-intercept form to identify the slope of the line, which gives you y = 2x + 3. Because parallel lines have identical slopes, the line passing through point P(4,6) will have the same slope, so the equation would be y = 2x + b. To find the exact equation of the line, substitute the coordinates of point P into this equation and solve for 'b', which gives you 6 = 2*4 + b. Thus, solving for 'b' we get b = -2. Therefore, the equation of the line that passes through point P(4,6) and is parallel to the given line is y = 2x - 2.
