The fraction of magazines that were delivered to families who were at home is 0.4 if total number of families are 25 out of which 10 were at home and rest are away.

Total number of families = 25

Families at home = 10

So the ratio of the required families

= Families at home/total number of families

= 10/25

= 2/5

To convert the fraction into decimal form, we have to divide and we get

= 0.4

Hence, the number of families in decimal to which magazines got delivered are 0.4

Correct statement for whose batch of cookies was more chocolaty is option (c) Neither, The batches were equally chocolaty

Consider Tanvi's cookies
Number of cups of chocolate chips = 1 cups

Number of cups of plain sugar = 3 cups

Total number of cups = 1 + 3 = 4  cups

Then the fraction of chocolate = 1 / 4

= 0.25

Consider Beth's cookies

Number of cups of chocolate chips = 2 cups

Number of cups of plain sugar = 6 cups

Total number of cups = 2 + 6 = 8  cups

Using partial quotient, the place value while subtracting is determined by the dividend.

divisor    dividend    quotient  multiplication  subtraction  new dividend

5             1175            200         200 * 5 = 1000        1175 - 1000 = 175

5             175             30            30 * 5 = 150             175 - 150    =  25    

5             25              5              5 * 5 = 25                 25 - 25      = 0

The quotient is then added as

= 200 + 30 + 5

= 235

Assuming the quotient was written 2. While subtracting, the dividend for the first value (1175) is in thousands. placing the the 2 in thousands makes it more than the dividend hence the 2 should be in hundreds

The distance between the point (5,12) and the line y = 5x + 12 is 4.90 units

If a point P with the coordinates (x₁, y₁), and we need to know its distance from the line represented by ax + by + c = 0

Then the distance of a point from the line is given by the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

Given: the point (5,12) and the line y = 5x + 12. The line can be written as

5x-y+12 = 0. Thus:

x₁ = 5, y₁ = 12, a = 5, b = -1, c = 12. Substitute these into the formula:

d = (ax₁ + by₁ + c) / √(a² + b²)

d = (5×5 + (-1×12) + 12) / √(5² + (-1)²)

d = 25/√26 = 4.90 units

The slope of the vertical line in the given graph is undefined.

The equation of the line is x = 2.

The slope of a vertical line is usually undefined because the horizontal change (change in x) is equal to 0. Thus, we cannot divide a number by 0. Therefore, the slope of a vertical line is undefined.

The line given is a vertical line that intersects the x-axis at 2. Its slope is undefined. Since its slope is undefined, it is impossible to write the equation of the vertical line in the traditional version of the point-slope form. Hence, it is written as x = b, where b is the point where the x-axis is intersected by the line.

Answer:

0.8461

To find the proportion of cherry tomatoes that have a diameter greater than 25 mm, we need to determine the proportion of the distribution that falls above this value. We can do this by converting the diameter of 25 mm to a z-score using the formula:

z-score = (value - mean) / standard deviation

For a diameter of 25 mm, the z-score is (3 - 22) / 2.5 = -2.8.

We can then use a z-table to find the proportion of the distribution that falls above this value. The z-table gives the area under the standard Normal curve to the left of a given z-score. To find the proportion of the distribution above the diameter of 25 mm, we need to find the area to the right of -2.8. From the z-table, we find that the area to the right of -2.8 is 0.8461. Therefore, approximately 84.61% of cherry tomatoes produced by the farm have a diameter greater than 25 mm.

The number of units manufactured at a cost of $8450 is x = 101.

A function is a relation where every input is connected to only one possible output from a set of available inputs.

The given function is C(x) = x² - 18x + 67.

To find the number of units manufactured at a cost of $8450, substitute C(x) = 8450 into the given equation and solve for x:

8450 = x² - 18x + 67

x² - 18x + 67 - 8450 = 0

x² - 18x - 8383 = 0

x² - 101x + 83x - 8383 = 0

x(x - 101) + 83(x - 101) =0

(x + 83)(x - 101) = 0

(x + 83) = 0 or (x -101) = 0

x = -83 or x = 101

Since the number of manufactured units cannot be negative, it follows

x = 101.

Hence, the number of units manufactured at a cost of $8450 is x = 101.

A circle is a shape consisting of all points in a plane that are given the same distance from a given point called the center.

We have given circle in the x, y-plane has the equation;

x² + y² -10x + 34y - 527 = 0

Now we will convert this equation to the standard form of the circle as;

x² -10x + y² + 34y = 527

[x² - 2(5)x] + [y² + 2(17)x] =527

[x² - 2(5)x + 5²] + [y² + 2(17)y + 17²] = 5² + 17² +527

(x - 5)² + (y + 17)² = 25 + 289 +527

(x - 5)² + (y + 17)² = 841

(x - 5)² + (y + 17)² = 29²

1 m/s = 2.3469362921 that gives you the above answer.

Using the dimensions of the figure, Thomas will have enough money to paint the surface area.

The dimensions of a two-dimensional figure are its lengths and widths.

The product of the length and width results in the surface area, which is stated in square units.

Since Thomas has $1,300, and the squared surface of the figure is equal to 260 square units, when $5 is multiplied into 260, the product is $1,300.

This amount is equal to the money available to Thomas for the painting.

If the dimensions produced a surface area of more or less than 260 square units, we can calculate Thomas' ability to complete the painting based on the information.

The length of the figure is given as 20 units.

The width of the figure is given as 13 units.

The surface area of the figure = 260 square units

The cost of paint per square unit = $5

The total cost for painting the figure = $1,300 ($5 x 260)

The amount available to Thomas for the painting = $1,300

Difference between the total cost and the available amount = $0.

Thus, we can assert that, given the dimensions of the figure, Thomas can complete the painting with the available funds.

A probability is given by the division of the number of desired outcomes by the number of total outcomes.

The total number of outcomes when a pair of dice is rolled is given by:

6² = 36.

As each throw has six outcomes.

The outcomes with a sum of 5 are given as follows:

(1,4), (2,3), (3,2), (4,1).

Hence 4 outcomes, and the probability that player A wins is of:

p = 4/36 = 1/9.

The outcomes with a sum of 4 are given as follows:

(1,3), (2,2), (3,1).

Hence the probability that B wins is given by:

p = 3/36 = 1/12.

Then the probability that a player wins on each trial is given by:

p = 4/36 + 3/36 = 7/36.

Then the expected number of rolls is given as follows:

E(X) = 1/(7/36) = 36/7 = 5.1 rolls.

Based on the loan amount and the number of years, the monthly payment, total cost of the car, and amount of interest to be paid are as follows:

Find the loan amount first:

= Car expense x ( 1 - down payment percent)

= 14, 800 x ( 1 - 12%)

= $13024

the monthly rate and the total number of periods, then:

Daily rate calculation:

= Annual Rate / Twelve-Month Period

= 4.5% / 12

= 0.375%

Counting periods:

= Years multiplied by Months per year

6 years times 12

72 months

These enable the following formula to determine the monthly payment:

= Loan Amount / 72-period Annuity Present Value Interest Factor of 0.375%

13024 / 62.995976235992

= $206.74

Total amount repaid on the auto loan:

= Amount Due Each Month x The Number of Months

= 206. 74 x 72

= $14, 885. 52
