The numeric value of the expression ((2.1)² + 5.2 - 7.2) x 7.1 is given as follows:
17.1.
How to obtain the numeric value of the expression?The expression for this problem is defined as follows:
((2.1)² + 5.2 - 7.2) x 7.1
The precedence of operators follows the PEMDAS acronym, as follows:
P: power operations.E: exponent operations, with the same precedence as power operations, depending which appears first on the expression.M: multiplication operations.D: division operations, with the same precedence as division operations, depending which appears first on the expression.A: addition operations.S: subtraction operations, with the same precedence as subtraction operations, depending which appears first on the expression.Hence the parenthesis takes precedence, thus:
(2.1)² + 5.2 - 7.2.
Then the power takes precedence, thus:
(2.1)² + 5.2 - 7.2 = 4.41 + 5.2 - 7.2
Addition and subtraction can be done in any order, hence:
4.41 + 5.2 - 7.2 = 2.41.
Then the multiplication is given as follows:
2.41 x 7.1 = 17.1.

On solving the provided question, we can say that - by formula of simple interest we have SI = [tex]2200 X 2 X 4/100 = > 17600/100 = > 176[/tex]
what is interest ?Multiplying the principal by the interest rate, time, and other factors yields simple interest. Simple return equals principle times interest times hours is the marketed formula. It is easiest to compute interest using this formula. A percentage of the principle balance is how interest is most commonly computed. For instance, he will only pay his portion of the 100% interest if he borrows $100 from a buddy and promises to pay it back with 5% interest. $100 (0.05) = $5. When you borrow money, you must pay interest, and when you lend money, you must charge interest. Most of the time, interest is expressed as a yearly percentage of the loan amount. The interest rate on the loan is known as this percentage.
here,
principal, p = 2200
rate, r = 2%
time, t = 4 rs,
so SI = P X R X T/100
SI -

Ellie wants double her savings of £9000 by investing her money for 18 years what interest rate does she need to look for?
She need a interest rate of 5.56%
Your wealth increases more quickly due to compound interest. Due to the fact that you will receive returns on both the money you invest and returns at the conclusion of each compounding period, it causes a sum of money to increase more quickly than with simple interest. As a result, you won't need to save as much money to achieve your objectives.

find the square root of 3.6 upto 2 decimal places. *With Solution I need*
Answer:
The square root is 1.90
Step-by-step explanation:
Given
[tex]x = \sqrt{3.6}[/tex]
Required
Find x
Express 3.6 as 36/10
So, we have:
[tex]x = \frac{\sqrt{36}}{\sqrt{10}}[/tex]
This gives
[tex]x = \frac{6}{\sqrt{10}}[/tex]
Rationalize
[tex]x = \frac{6}{\sqrt{10}}*\frac{\sqrt{10}}{\sqrt{10}}[/tex]
[tex]x = \frac{6\sqrt{10}}{10}[/tex]
Using a calculator
[tex]\sqrt{10} \approx 3.16[/tex]
So, we have:
[tex]x = \frac{6*3.16}{10}[/tex]
[tex]x = \frac{18.96}{10}[/tex]
[tex]x = 1.896[/tex]
Approximate

Sam rolls a fair dice and flips a fair coin.
What is the probability of obtaining an odd number and a head?
There are six sides to a die and only one side has a two, so the probability of rolling a 2 is 1/6.
There are two sides to a coin and only one side has a head, so the probability of its coming up heads is 1/2.
The two events (rolling a die and flipping a coin) are independent, so the probability of both events occurring is (1/6)(1/2) = 1/12

Answer:
The first table is correct
Step-by-step explanation:
x=Yellow Prob
0 .5625
1 .375
2 .0625
The attached document shows a tree diagram with all 16 outcomes. Each outcome has probability 1/16.
The numbers at the right show the numbe of yellows for each outcome. There are 9 outcomes with 0 yellow (prob = 9/16).
There are 6 outcomes with 1 yellow (prob = 6/16)
There is 1 outcome with 2 yellow (prob = 1/16)
Sorry about the watermarks--distracting!
Based on the given set of values, we can note that the first table is correct
What is Probability?This refers to the calculations of the way an event is most likely to occur.
Hence, the table for x=Yellow Prob
0 .5625
1 .375
2 .0625
For each outcome, there is probability 1/16.
The numbers at the right show the number of yellows for each outcome. There are 9 outcomes with 0 yellow (prob = 9/16).
There are 6 outcomes with 1 yellow (prob = 6/16)
There is 1 outcome with 2 yellow (prob = 1/16)
Hence, because the calculated values are consistent with the values in the first table, then we can conclude that the first table is correct.

What are discrete random variables?Those random variables, who take only distinct values, are called discrete random variables.
What are continuous random variables?Those random variables, who take any value from a given continuous interval of real numbers are called continuous variables.
For the given first and second cases, the time between customers entering a checkout lane, or the weight on a truck can be any value in an interval of real numbers. Its not assuming distinct values and it can be any value in a continuous real number interval. Thus, they are continuous random variable.
For the given cases, from case third to fifth, the number of errors, the number of clerical errors, and the number of days, all can only be integers and thus, they are distinct, non-continuous in any non-zero sized interval, thus, they are discrete random variables.

Step-by-step explanation:
Complete the following indirect proof (proof by contradiction).
Given: Adjacent angles LA and ZB, formed by the intersection of two lines
Prove: At least one of the angles LA and B has measure 90° or greater
First, we assume that this conclusion is false. In other words, we assume that the contrary statement "none of the two angles has measure [tex]90^{\circ}[/tex] or greater" is true.
The assumption is equivalent to the following two statements:
(1) [tex]m\angle A\text{ } \boxed{ < 90^{\circ}}[/tex]
(2) [tex]m\angle B\text{ } \boxed{ < 90^{\circ}}[/tex]
Using (1) and (2) and the addition properties of inequalities, we conclude that [tex]m\angle A+m\angle B \text{ } \boxed{ < } \text{ } 180^{\circ}[/tex].
On the other hand, two adjacent angles form a linear pair. Thus, the last statement contradicts the Linear Pair Property, which states that for a linear pair of angles [tex]\angle A[/tex] and [tex]\angle B[/tex], [tex]m\angle A+m\angle B \text{ } \boxed{=} \text{ } 180^{\circ}[/tex].
Therefore, the assumption made is false, and the statement "at least one of the angles [tex]\angle A[/tex] and [tex]\angle B[/tex] has measure [tex]90^{\circ}[/tex] or greater" is true.
A figure was dilated so that the new area is 16 times bigger than the original area. Find
one possible set of perimeters for the two figures.
Please Explain!!
One possible set of perimeters for the two figures is 4x and 16x.
What is Dilation?Dilation is one of the type of transformation where the size of the object is made smaller or larger without affecting the shape.
Let A be the area of the original figure.
New area after dilation = 16A
Suppose that the figure is a square.
Area of a square is the square of it's side length and perimeter is four times the length of one side.
Let 'x' be the length of a side of the original figure.
Area of the original figure, A = x²
Perimeter of original figure = 4x
New area = 16 A = 16 x² = (4x)²
So the side length of new figure = 4x
Perimeter of new figure = 4 (4x) = 16x
Hence one of the possible set of perimeters for the two figures given is 4x and 16x.

store, the liquid detergent is priced at $14.99 for 64
loads of laundry and the same brand of powder
detergent is priced at $15.99 for 80 loads. Which is
the better buy, the liquid, or the powder
Therefore , the solution of the given problem of percentage comes out to be 4250 mg, or 4.25 g and the percentage increase is 50%.
A percentage is what?A% is a number that can be expressed as a decimal or a fraction and indicates what proportion of 100 it is. Put 100 in the denominator and the percentage amount in the numerator to turn a percentage into a fraction.
Here,
This "Nutritional Facts" table indicates that 85 mg of potassium, or 2% of the daily recommended value, corresponds to the row "Potassium".
By using the unitary method, (85/2) mg of potassium will represent 1% of the daily required intake.
As a result, 4250 mg of potassium, or 100% of the daily allowance, will be required: (85/2 * 100).
The entire quantity of potassium that is advised for daily consumption is 4250 mg, or 4.25 g.
(New value) − (Initial value) / (Initial value) = percent change. * 100%.
Here,
Initial value: $1.50 (the 1995 fare).
New value equals $2.25 for the 2008 fare.
Therefore,
percentage variation
= [(2.25 - 1.50) / 1.50] .50] * 100%
= (0.75 / 1.50) * 100%
= 0.5 * 100%
= 50%.
Positive indications of the transition point to an increase in fare.
The percentage increase is therefore 50%.

$1
a) How many people ate dinner? Including Stewart
9514 1404 393
Answer:
0 people ate dinner
23 people ate lunch
Step-by-step explanation:
If the bill is split evenly between x people, then each pays 500/x.
Splitting the bill between x-1 people means each pays 500/(x -1).
When the difference in those amounts is 1.00, we have ...
500/(x -1) -500/x = 1
500 = x(x -1)
Completing the square gives ...
500.25 = (x -0.5)²
x = 0.5 +√500.25 ≈ 22.866 ≈ 23
Check
With 22 people splitting the $500 bill, the amount each pays is ...
$500/22 ≈ $22.73
With 23 people splitting the bill, the amount each pays is ...
$500/23 ≈ $21.74
The difference is $0.99, about $1.00. This is as close as you will get with these numbers.
