The mass of a 6.75 kg bowling ball is equivalent to 67.5 hg, 67.5 dag, 6750 g, 67500 cg, or 6750000 mg.

Mass is a measure of the amount of matter an object contains. The equation used to convert between mass units is:

Mass (m) = Mass (M) × Conversion Factor

For example, if we want to convert 6.75 kg to hg (hectograms), the formula and calculation would be:

m (hg) = M (kg) × 100

m (hg) = 6.75 kg × 100

m (hg) = 67.5 hg

Similarly, we can convert 6.75 kg to dag (decagrams) using the formula:

m (dag) = M (kg) × 10

m (dag) = 6.75 kg × 10

m (dag) = 67.5 dag

To convert 6.75 kg to g (grams), the formula and calculation are:

m (g) = M (kg) × 1000

m (g) = 6.75 kg × 1000

m (g) = 6750 g

We can also convert 6.75 kg to cg (centigrams) using the formula:

m (cg) = M (kg) × 10000

m (cg) = 6.75 kg × 10000

m (cg) = 67500 cg

Finally, to convert 6.75 kg to mg (milligrams), the formula and calculation are:

m (mg) = M (kg) × 1000000

m (mg) = 6.75 kg × 1000000

m (mg) = 6750000 mg

In conclusion, the mass of a 6.75 kg bowling ball can be equivalent to 67.5 hg, 67.5 dag, 6750 g, 67500 cg, or 6750000 mg.

Answer:

To find an appropriate measure of center, we need to determine the typical or central value of the data. There are several measures of center, such as mean, median, and mode.

However, in this case, we need to consider the extreme value of 8, which is significantly lower than the rest of the values. This value may be an outlier, and including it in the calculation of the mean could skew the result.

Therefore, the most appropriate measure of center in this case would be the median, which is the middle value when the data set is ordered.

To find the median, we first need to order the data set:

8, 20, 22, 23, 23, 24

There are six values in the data set, so the median will be the average of the two middle values, which are 22 and 23.

Median = (22 + 23) / 2 = 22.5

Therefore, the most appropriate measure of center for this data set would be the median of 22.5.

Given that it is not raining, there is a [tex]10.67[/tex]% probability that a man is holding an umbrella, or around [tex]0.1067[/tex].

As probabilistic arguments sometimes produce outcomes that appear contradictory or counterintuitive, probability is usually regarded as one of the most challenging topics of mathematics.

Probability is the likelihood that something will occur or the probability that something will happen. Probability is the measure of how probable it is that a coin will land heads up after being tossed into the air.

To find [tex]P(B|A)[/tex],

[tex]P(B|A) = P(A and B) / P(A)[/tex]

[tex]P(B|A) = P(A|B) * P(B) / P(A)[/tex]

Putting it all together,

[tex]P(A|B) = P(B|A) * P(A) / P(B)[/tex]

[tex]= [P(A|B) * P(B)] / P(A)[/tex]

[tex]= [P(A and B) / P(B)] * P(A) / P(A)[/tex]

[tex]= P(A and B) / P(B)[/tex]

Therefore,

[tex]P(B|A) = P(A and B) / P(A)[/tex]

[tex]= P(A) * P(B|A) / P(B)[/tex]

[tex]= 0.4 * (1 - 0.75) / 0.75[/tex]

[tex]= 0.1067[/tex]

So the probability that a person is carrying an umbrella given that it's not raining is approximately [tex]0.1067[/tex], or about [tex]10.67[/tex]%.

The double number line, along with the formula y = 8x + 58, can be used to determine the number of adults needed to supervise a given number of children on a field trip.

The double number line shows the relationship between the number of adults and the number of children they can supervise on a field trip. The table below represents the same relationship:

Adults  Children

8         66

15         99

The formula used to calculate the number of children supervised by a given number of adults is y = 8x + 58, where y is the number of children and x is the number of adults. This formula can be derived by looking at the two points given in the table above. For 8 adults, the corresponding number of children is 66, so 66 = 8x + 58. Solving this equation yields x = 7, which means that 7 adults are needed to supervise 66 children. At 15 adults, the number of children goes up to 99, so 99 = 8x + 58. Solving this equation yields x = 11.25, which means that 11.25 adults are needed to supervise 99 children.

The equation can also be used to calculate the number of adults needed to supervise a given number of children. For example, if the field trip involves 45 children, the equation y = 8x + 58 can be used to calculate the number of adults needed. Substituting 45 for y yields 45 = 8x + 58, which when solved yields x = 5.625. This means that 5.625 adults are needed to supervise 45 children.

Daniel and Liz have conflicting claims about how much time students spend on homework.

Daniel claims that more than half of students spend 2 1/2 hours or more on homework, while Liz claims that more than half spend less than 2 1/2 hours. To determine who is correct, we must look at the actual data.

If, when we look at the data, we find that more than half the students spend 2 1/2 hours or more on homework, then Daniel is correct. Conversely, if more than half the students spend less than 2 1/2 hours on homework, then Liz is correct. It is important to note that the answer may depend on the sample size of the data we are looking at.

If the sample size is small, then it may be difficult to definitively answer the question. However, if the sample size is large, then it may be possible to provide a definite answer. In conclusion, to determine who is correct, we must look at the actual data. If the sample size is large enough, then it may be possible to definitively answer the question of who is correct.

Daniel says that more than half of the students spent 2.5 hours or more on homework, while Liz says more than half of the students spent less than 2.5 hours on homework. Liz's assertion is correct. So, Liz is correct since more than half of the students spent less than 2.5 hours on homework.

If Daniel were correct, the total percentage would be more than 100 percent, which is impossible since the total percentage is always 100 percent when the data set is of a limited population. The arithmetic mean of the time the students spend on their homework can be calculated using a statistical concept called a measure of central tendency.

The mean is used in this case. A measure of central tendency is a way of summarizing a data set using a single value that represents the entire collection of data in a condensed form. The mean is calculated by adding up all of the data and then dividing by the number of data points. To discover if the assertion that Liz is correct is accurate, more data is needed.

The factored form of the quadratic expression 2x² - 9x - 11 is: a. (2x - 11)(x + 1).

To factor the quadratic expression 2x² - 9x - 11, we need to find two binomials that when multiplied together give us the original quadratic expression. Here are the steps to follow:

Step 1: Multiply the coefficient of the x² term (2) and the constant term (-11) to get -22.

Step 2: Find two numbers whose product is -22 and whose sum is the coefficient of the x term (-9). These numbers are -11 and 2.

Step 3: Rewrite the quadratic expression by splitting the x term into -11x + 2x, using the two numbers found in step 2:

2x² - 11x + 2x - 11

Step 4: Group the first two terms and the last two terms together and factor out the greatest common factor (GCF) of each group:

(2x² - 11x) + (2x - 11)

x(2x - 11) + (2x - 11)

Step 5: Factor out the common binomial factor of (2x - 11):

(2x - 11)(x + 1)

The answer is: a. (2x - 11)(x + 1)

To find the number of points at which the graph of the function intersects the x-axis, we need to find the roots of the equation:

4x^2 - 9x + 9 = 0

We can use the quadratic formula to find the roots:

x = (-b ± sqrt(b^2 - 4ac)) / 2a

In this case, a = 4, b = -9, and c = 9, so:

x = (-(-9) ± sqrt((-9)^2 - 4(4)(9))) / 2(4)

x = (9 ± sqrt(81 - 144)) / 8

x = (9 ± sqrt(-63)) / 8

Since the discriminant is negative, the roots are complex and the graph does not intersect the x-axis. Therefore, the answer is b. 0.

i) The expression relating price and output assuming it is linear is Price per unit = -20 × Number of units sold + c.

ii) The total cost function, assuming it is linear is 2000 + 10 × Number of units sold.

iii)  The business woman need to produce 114 products to achieve breakeven.

(i) The expression relating price and output assuming it is linear can be written as:

Price per unit = m × Number of units sold + c

where m is the slope of the line and c is the y-intercept.

We can find the slope by using the two points (20, 300) and (13, 440):

m = (440 - 300) / (13 - 20) = 140 / (-7) = -20

So, the expression relating price and output is:

Price per unit = -20 × Number of units sold + c

(ii) The total cost function assuming it is linear can be written as:

Total cost = Fixed cost + Variable cost per unit × Number of units sold

Given that the fixed cost of production is GH₵2,000 with a variable cost per unit of GH¢10, the total cost function can be expressed as:

Total cost = 2000 + 10 × Number of units sold

(iii) To find the level of production at which the business woman will breakeven, we need to find the point at which the total cost equals the total revenue. Since the total revenue is simply the product of the price per unit and the number of units sold, we can set these two equations equal to each other:

Price per unit × Number of units sold = Total cost

Substituting the expressions we found in parts (i) and (ii), we get:

(-20 × Number of units sold + c) × Number of units sold = 2000 + 10 × Number of units sold

Simplifying and solving for the number of units sold, we get:

20 × Number of units sold^2 - 20c × Number of units sold - 2000 = 0

Using the quadratic formula, we get:

Number of units sold = (-(-20c) ± sqrt((-20c)^2 - 4 × 20 × (-2000))) / (2 × 20)

Simplifying, we get:

Number of units sold = (c + sqrt(c^2 + 2000)) / 2

Since we know that the business woman can sell 300 units a day at a price of GH¢20 and 440 units a day at a price of GH¢13, we can set up a system of equations to solve for the y-intercept, c:

-20 × 300 + c = 20c + 2000

-20 × 440 + c = 13c + 2000

Solving this system of equations, we get:

c = 2400/3 ≈ GH₵800

Therefore, the level of production at which the business woman will breakeven is:

Number of units sold = (800 + sqrt(800^2 + 2000)) / 2 ≈ 113.7 units

She should produce at least 114 units to breakeven.

The maximum volume of paint that can be stored in the cylindrical tank occurs when it is completely filled. The formula for the volume of a cylinder is:

V = πr^2h

where V is the volume, r is the radius, and h is the height.

In this case, the height of the cylindrical tank is 8 feet and the radius is 3 feet. So we can substitute these values into the formula to get:

V = π(3^2)(8)

V = π(9)(8)

V = 72π

Therefore, the maximum volume of paint that can be stored in the tank is 72π cubic feet, which is approximately 226.2 cubic feet if we round to one decimal place.

If Jasper and Corey have saved up a total of $78.0 and Jasper has saved 6 dollars more than twice as much as Corey, Corey has saved $24, for a total of $78.

Let's use C to represent the amount of money Corey has saved.

We know that Jasper has saved 6 dollars more than twice as much as Corey, so we can write an equation to represent this relationship:

J = 2C + 6

where J is the amount of money Jasper has saved.

We also know that the total amount of money saved by Jasper and Corey is $78, so we can write another equation to represent this:

J + C = 78

Now we can substitute the first equation into the second equation to get an equation with only one variable:

(2C + 6) + C = 78

Simplifying the equation, we get:

3C + 6 = 78

Subtracting 6 from both sides, we get:

3C = 72

Dividing both sides by 3, we get:

C = 24

Therefore, Corey has saved $24. We can use the first equation to find out how much Jasper has saved:
