The range is the set of y values.

There are 0.857 quarts of pure antifreeze that must be added to 3 quarts of a 10% antifreeze solution to obtain a 30% antifreeze solution.

The percentage is defined as a ratio expressed as a fraction of 100.

We have been given that there is 10% times 3 quarts or 0.3 quarts of antifreeze in the current mix and we want a 30% solution.

Let the amount of pure antifreeze to be added would be x

The equation to solve becomes,

⇒ (0.3 + x )/(3 + x) = 0.3

⇒ (0.3 + x ) = 0.3 × (3 + x)

⇒ (0.3 + x ) = 0.9 +0.3x

⇒ 0.7x = 0.6

⇒ x = 0.857

Therefore, we need to add 0.857 quarts of pure antifreeze to the current solution to make a 30% solution.

The required expression is 17x + 2124 which represents the combined total profit (in dollars) TechWiz made from MP3 and DVD players last week.

Algebraic expressions are mathematical statements with a minimum of two terms containing variables or numbers.

Arithmetic operations can also be specified by adding,  subtracting, dividing, and multiplying built-in functions.

Let the number of MP3 players TechWiz sold last week would be x.

Here TechWiz Electronics makes a profit of $35 for each MP3 player sold.

Last week, TechWiz sold a combined total of 118 MP3 and DVD players.

As per the condition,

So the required expression for the combined total profit would be:

= 35x + 18(118-x)

= 35x + 2124 - 18x

= 17x + 2124

Hence, the required expression is 17x + 2124 which represents the combined total profit (in dollars) TechWiz made from MP3 and DVD players last week.

The total number of condensed milk required is 8/3=2 2/3.

The total number of pan is 4

The condensed milk required for each pan is 2/3

The pieces of a whole are how fractions are described in mathematics. One or more objects may make up the whole. When we cut a piece of pizza in real life from the entire pizza, the part represents the percent of the pizza.

The total number of condensed milk is 4.  2/3=  8/3

For first pan let the measuring cup is 1/4  then the condensed milk is measured as

1/4  .  2/3  =1/6    

For second pan let the measuring cup is 1/2  , then the condensed milk is measured as

P(E) + P(F) = 1.4

Answer:

Step-by-step explanation:

Based on the calculations, the IQR of this data is equal to 2.

How to determine the IQR of this data?

IQR is an acronym for interquartile range and it is a measure of the middle 50% of data values when they are ordered from lowest to highest.

Next, we would order the data from lowest to highest and then determine the median as follows:

Data = {1, 4, 4,} 4, {4, 6, 5}

Median = 4.

For Q₁ of the lower half of the data, we have:

Lower half = {1, 4, 4,}

Q₁ = 4.

For Q₃ of the upper half of the data, we have:

Upper half = {4, 6, 5}

Q₃ = 6.

Mathematically, IQR is the difference between quartile 1 (Q₁) and quartile 3 (Q₃):

IQR = Q₃ - Q₁

IQR = 6 - 4

IQR = 2.

The results of those seven rolls that are shown shows that the range is 5.

The range is the size of the smallest interval which contains all the data and provides an indication of statistical dispersion. It is measured in the same units as the data.

Given that a six-sided die is rolled 7 times, to give 1, 4, 4, 4, 4, 6, 5, we need to find the range,

The numbers that are gotten include:

1, 4, 4, 4, 4, 6, 5.

It should be noted that range is calculated as:

The number of people that must attend for him to break even

is 240.

Given that the owner charges $7 per ticket, every customer receives a brochure that costs the owner $2 for each person and the owner must pay his band $1200.

We are required to find the people must attend for him to break-even.

Break even point is the point at which there is not any profits or losses.

We have to first form the equation for the break even.

Suppose the number of people be x.

Cost to the owner will be 1200+2x.

Revenue will be 7x.

Break even point will be at the point where 7x=1200+2x

7x-2x=1200

5x=1200

x=240

Hence the number of people that must attend for him to break even

is 240.

The expression (128 + 32) when rewritten using factoring is 4(32 + 8)

The expression in the question s given as

(128 + 32)

Express the numbers 128 and 32 as the product of their factors

i.e. we factor out 4 from the expression

So, we have

(128 + 32) = (4 * 32 + 4 * 8)

Next, we factor out the common factor (i.e. 4) from the expression

So, we have

(128 + 32) = 4 * (32 + 8)

Rewrite the above expression as follows

(128 + 32) = 4(32 + 8)

Answer:

  95

Step-by-step explanation:

You want the sum of 38 and 57 by making use of the GCF and the distributive property.

The GCF of two numbers can be found by looking at their difference (or their remainder when one divides the other). Here, that is ...

  57 -38 = 19

This value is a factor of both numbers, so is their GCF.

The distributive property tells us how to express the sum with the GCF factored out:

  38 +57 = 19(2 +3)

Then the sum is ...

  19(2 +3) = 19(5) = 95

The sum is 95.

The Total amount after 4 years will be $3000 and interest will be $500.

The rate at which you borrow or lend money is called the simple interest. If a borrower takes money from a lender, an extra amount of money is paid back to the lender. The borrowed money which is given for a specific period is called the principal. The extra amount which is paid back to the lender for using the money is called the interest.

You calculate the simple interest by multiplying the principal amount by the number of periods and the interest rate. Simple interest does not compound, and you don’t have to pay interest on interest. In simple interest, the payment applies to the month’s interest, and the remainder of the payment will reduce the principal amount.

The simple interest calculation's mathematical formula:

A = P (1+rt)

P = Principal Amount

R = Rate of interest

t = Number of years

A = Total accrued amount (Both principal and the interest)

Interest = A – P.

Total amount after 4 years

⇒ $2,500 (1+5%×4)

⇒ $2,500 ×1.2\

⇒ $3000

interest= $3000 - $2,500=  $500.

The radius of the large circle would just be the diameter of one of the smaller circles, so 14 inches.

In order to solve this, we will need to find the area of the large circle and subtract the area of two smaller circles.

I'll be using pi as 3.14 for this.

Large Circle:

[tex]A = \pi r^{2}\\A = \pi (14)^{2}\\A = 196\pi \\A = 615.44[/tex]

Smaller Circle:

[tex]A = \pi r^{2}\\A = \pi (7)^{2}\\A = 49\pi \\A = 153.86[/tex]

Now we just simply subtract them.

615.44 - (2 * 153.86)

= 307.72 inches

You might've noticed that is exactly half of the area of the larger circle.

That's because if you halve the radius of a circle, you will get one fourth of original area.

It is very less possibilities that the first half of the terms are either all 0's or all 1's.

According to the question, the probability to toss the coins which are marked as 0 or 1 is: 2

And the getting favorable outcomes that is 0 or 1: 1

Therefore, the probability for the given possibility is written as:

P(A) = n(A)/n(S) = 1/2

Hence, for infinite times, it is the half of the possibilities that the first half is either 0 or 1.

What is probability?

Probability can be defined as the outcomes which can be predicted or which can be calculated. It is the ratio of the total number of the favored outcomes to the total number events. The value of the probability is always less than1.

The measure of the angles shown is 90 degrees

A line is defined as the shortest distance between two points while the point where two lines meet is known as an angle.

From the given diagram, the sum of both adjacent angles is supplementary to have:

x + 96 + 96 + x = 180

2x + 192 = 180

2x = 180 - 192

2x = -12

x = -6

Substitute the value of x into the expression

<d = x + 96

<d = -6 +96

<d = 90 degrees

y=1/2x-13/2 is equation of the line that satisfies the given conditions. Through (1, −6) and parallel to the line x + 2y = 6

y=mx+c

where m is the slope.

Firstly we need to find the slope of the line  x - 2y = 6 by using slope intercept form, y=mx+c.

-2y=6-x

2y=x-6

y=1/2 x-6

m=1/2 slope of the line  x - 2y = 6.

For parallel lines slope will be same.

Now Use y = mx + b and the point (1,-6) to find b, the y-intercept.

-6= (1/2)*1 + b

-6-1/2=b

-13/2=b

y=1/2x-13/2 is the equation of line.

Therefore y=1/2x-13/2 is the line parallel to x + 2y = 6.
