1) a supermarket sells articles during the festival seasons with a 10% discount. find the new price of the following articles.

i) A CFL bulb if the marked price is Rs. 280

ii) A bunion if the marked price is Rs. 650.

iii) A gas cooker if the marked price is Rs. 7500

Answer:

5 inches

Step-by-step explanation:

Area is just length time width (how wide it is). Since we have two values, we can make an equation to solve for the variable. Because we're trying to find width, we'll use "w" as the variable for this equation.

The equation can be seen as A=l*w, and if we substitute A and l, we can make the equation:

25=5*w, or 25=5w

Since w is multiplied to 5, and we need to isolate w, we have to do the inverse (divide) both sides.

25/5=5

5w/5=w

From this, we get w=5

The hypothesis that should be written as an inequality is B. the alternative hypothesis.

The alternative hypothesis is a statement that contradicts the null hypothesis and is used to determine if there is a significant difference between two variables. It is often written as an inequality to show that there is a difference between the two variables being tested.

For example, if we are testing whether a new drug is more effective than a placebo, the alternative hypothesis would be written as "the new drug is more effective than the placebo," or in inequality form, "the effectiveness of the new drug > the effectiveness of the placebo."

In contrast, the null hypothesis is a statement that there is no significant difference between the two variables being tested. It is usually written as equality, such as "the new drug is equally effective as the placebo," or "the effectiveness of the new drug = the effectiveness of the placebo."

Therefore, the alternative hypothesis is the one that should be written as an inequality.

Answer:   (^-^)    2

Step-by-step explanation:

2+7 is 9 you divided 18 by 9 which it is 2

The slope of the line segment joining the two points given (-6,-3) and (0, -1.5) expressed in fraction form as required in the task content is; m = 1/4.

It follows from the task content that the slope of the line segment joining the two points given (-6,-3) and (0, -1.5) be determined.

On this note, it follows from the slope formula that slope;

m = (y2 - y1)/(x2 - x1)

Therefore, the slope of the line segment joining the two points is;

m = (-1.5 - (-3))/(0 - (-6))

m = 1.5/6

m = 1/4.

Ultimately, the slope of the line segment joining the two points given (-6,-3) and (0, -1.5) expressed in fraction form as required in the task content is; m = 1/4.

Hope this helps you. I apologize if it’s incorrect.  

Answer: x = -6

Step-by-step explanation: Start by changing the - 4 to plus a negative 4 so that you know you're distributing a -4 through the parentheses.

So we have -8x - 4x + 16 = 88.

Simplifying the left side further gives us -12x + 16 = 88.

Now subtract 16 from both sides to get -12x = 72.

From here it should be easy to find the x = -6.

The measure of central tendency that is used by the professor is; Mode

A measure of central tendency is defined as a single value that attempts to describe a set of data by identifying the central position within that set of data. The types of measures of central tendency are;

1) Mean; This is defined as the average value of a given set of data.

2) Median: This is defined as the midpoint of a frequency distribution of observed values or quantities, such that there is an equal probability of falling above or below it.

3) Mode: This refers to the value in a given set of data that has highest occurrence frequency.

In this case, the professor notes that most students in his class earned a grade of b. Thus, this is the mode.

Answer:

D does not show an equivalent rate

Step-by-step explanation:

we first need to find out how many words typed per minute so we divide 75 by 3 (3 divided by 3 is 1 and what we do to one side must be done to the other)

75 ÷ 3 = 25

25 word per 1 minute

now we need to multiply the minute by 25 to get the number of words typed

25(words) x 1(minute) = 25 words in 1 minute(so A is correct)

25(words) x 2(minute) = 50 words in 2 minutes(so B is correct)

25(words) x 4(minute) = 100 words in 4 minutes (so C is correct)

25(words) x 5(minute) = 125 words in 5 minutes(so D is incorrect)

Answer:

10 centimeters.

Step-by-step explanation:

First, we need to remember what's the formula to get the volume of a rectangular solid and a cube.

The volume of the first equals:

Volume = Length x Width x Height

While the volume of the cube is:

\(Volume = a^{3}\) where a is the edge.

We are given the measures of the rectangular solid so we can calculate its volume:

\(Volume= (20)(5)(10)=1000\) cubic cms.

Now, we know that  both the volume of the rectangular solid and the cube are the same so we will use this information to calculate the edge of the cube.

\(1000=a^3 \\\sqrt[3]{1000} =\sqrt[3]{a^3} \\10=a\)

Thus the length of an edge of the cube is 10 centimeters

The required algebraic expression is 14/2

What is an algebraic expression?

An expression that includes variables, constants, and algebraic operations is known as an algebraic expression in mathematics (addition, subtraction, etc.). Terms combine to form expressions.

With the help of integer constants, variables, and the addition, subtraction, multiplication, and division operations in basic arithmetic, an algebraic expression is created. The algebraic statement 5x + 6 is an illustration. In this case, 5 and 6 are fixed values, while x is a variable. Additionally, the variables can be either simple variables with alphabets like x, y, or z or complex variables with names like x², x³, etc. Polynomials are another name for algebraic expressions. Variables (also known as indeterminates), coefficients, and non-negative integer exponents of variables make up a polynomial expression.

The value of P(AnB) is calculated using:

P(AnB) = P(a|b) * P(b)

Substitute the known values;

P(AnB) = 0.55 * 0.23

Answer:

100 packets

Step-by-step explanation:

Given :

Cost = fixed cost + variable cost

Fixed cost = $500

Variable cost = $10

Sales price = $15

Let :

Number of packets = x

To break even :

fixed cost + variable cost = sales made

500 + 10x = 15x

500 = 15x - 10x

500 = 5x

x = 500 / 5

x = 100

The following bit vector represents a disk where blocks 1,5,8,11,14 are free, and the rest is allocated is False.

What is Bit-Vector?

Bits are stored in a bit array, which is a type of array data structure. An easy set data structure can be implemented using it. Bit-level parallelism in hardware can be quickly used by a bit array to perform operations.

When files are generated, the system allots space for them by keeping track of the free disk blocks. Additionally, free space management becomes essential in order to utilise the space freed up by deleting the files.

The system keeps track of the disk blocks that are not assigned to any files or directories in a list called free space. Implementing the free space list primarily entails:

A bitmap or bit vector is a sequence or group of bits, where each bit stands for a disk block. The bit has two possible values: 0 and 1: 0 means the block is allocated, and 1 means the block is free.

A bitmap of 16 bits can be used to represent the given instance of disk blocks on the disk in Figure 1 (where green blocks are allocated) as 0000111000000110.

The equation that relates running time x and walking time y to his total time (12 minutes) is 120 = 6x + 15y.

2a) The 1,600 meters Eric will cover if he runs for x minutes and walks for y minutes can be calculated as follows

Distance covered by running for x minutes = 200x

Distance covered by walking for y minutes = 80y

Total distance covered by Eric in 12 minutes= Distance covered by running + Distance covered by walking

1,600 = 200x + 80y

Thus, the equation for the 1,600 meters

Eric will cover if he runs for x minutes and walks for y minutes is 1,600 = 200x + 80y.

2b) The equation that relates running time x and walking time y to his total time (12 minutes) can be calculated as follows

Time taken to run x minutes = (x/200) × 60 minutes

                                               = 3x/5 minutes

Time taken to walk y minutes = (y/80) × 60 minutes

                                                 = 3y/2 minutes

Total time taken = Time taken to run + Time taken to walk

12 = 3x/5 + 3y/2
