looking at the side-by-side boxplots from the previous question, should the mean for boxplot #3 be less than, greater than, or roughly equal to its median?

The ball is 7 feet high when it leaves the child’s hand

Given that

h(x) = -x^2 + 6x + 7

When it leaves his hand, we have

x = 0

This gives

h(0) = -(0)^2 + 6(0) + 7

Evaluate

h(0) = 7

Here, we have

h(x) = -x^2 + 6x + 7

Differentiate and set to 0

-2x + 6 = 0

So, we have

x = 3

The maximum height is

hmax = -3^2 + 6(3) + 7

hmax = 16

This means that h(x) = 0

So, we have

-x^2 + 6x + 7 = 0

This gives

x^2 - 6x - 7 = 0

Expand

x^2 + x - 7x - 7 = 0

Factor

x(x + 1) -7(x + 1) = 0

So, we have

(x - 7)(x + 1) = 0

Solve for x

x = 7 or x = -1

Hence, the distance is 7 feet

Contestants on a game show spin a wheel like the one shown in the figure above. Each of the four outcomes on this wheel is equally likely and outcomes are independent from one spin to the next.

The contestant spins the wheel.

If the result is a skunk, no money is won and the contestant's turn is finished.

If the result is a number, the corresponding amount in dollars is won.

The contestant can then stop with those winnings or can choose to spin again, and his or her turn continues.

If the contestant spins again and the result is a skunk, all of the money earned on that turn is lost and the turn ends.

The contestant may continue adding to his or her winnings until he or she chooses to stop or until a spin results in a skunk.

Expressions consist of basic mathematical operators. The product of [tex]\frac{1}{2x} -\frac{1}{4}[/tex] & [tex]5x^{2} -2x +6[/tex] is not equal to the product of [tex]\frac{1}{2x} -\frac{1}{4}[/tex] and [tex]5x^{2} -2x +6[/tex]

Product of an Equation:

In mathematics, a product is a number or quantity obtained by multiplying two or more numbers. Example: 4 × 7 = 28, where the number 28 is said to be the product of 4 and 7. Another example: 6 times 4 is 24, so 6 multiplied by 4 is 24. The product of two positive numbers is a positive number, as if the product of two negative numbers is also positive (e.g., -6 × -4 = 24).

Now,

(A) We need to find the product of two given expressions.

[tex]\frac{1}{2x} -\frac{1}{4}[/tex] ×  [tex]5x^{2} -2x +6[/tex]

To multiply two given expressions, first multiply the first term in the first parenthesis by the entire expression in the second term, then do the same for the second term in the first parentheses.

[tex]\frac{1}{2x} -\frac{1}{4}[/tex] × [tex]5x^{2} -2x +6[/tex]

⇒ [tex]\frac{1}{2x} * [5x^{2} -2x +6] - \frac{1}{4} * [5x^2 - 2x +6][/tex]

⇒ [[tex]\frac{1}{2x} * 5x^2[/tex] - [tex]\frac{1}{2x} *2x[/tex] + [tex]\frac{1}{2x}* 6[/tex] ] - [ [tex]\frac{1}{4} * 5x^2 + \frac{1}{4} * 2x - \frac{1}{4}*6[/tex]]

Now, simplify the equation:

[tex]\frac{5x}{2} -1 + \frac{3}{x} - \frac{5x^2}{4} +\frac{x}{2} +\frac{3}{2}[/tex]

Rearranging the equation:

[tex]-\frac{5x^2}{4} + \frac{6x}{2} -2.5 +\frac{3}{x}[/tex]

Thus, the product of the two expressions is [tex]-\frac{5x^2}{4} + \frac{6x}{2} -2.5 +\frac{3}{x}[/tex].

(B) To compare the two expressions we will find the value of the two given expressions,

[tex]\frac{1}{2x} -\frac{1}{4} * 5x^{2} -2x +6[/tex] = [tex]-\frac{5x^2}{4} + \frac{6x}{2} -2.5 +\frac{3}{x}[/tex]

For the value of:

[tex]\frac{1}{4x} - \frac{1}{2} * 5x^{2} -2x +6[/tex]

simplifying the equation:

    [tex]\frac{1}{4x} - \frac{1}{2} * 5x^{2} -2x +6[/tex]

⇒ [tex][\frac{1}{4x} * (5x^{2} -2x +6)] - [\frac{1}{2} * (5x^{2} -2x +6)][/tex]

⇒ [tex]-\frac{5x^2}{2} + \frac{9x}{4} + 3.5 +\frac{3}{2x}[/tex]

As you can see, the result of the product of the two expressions is different.

Expressions consist of basic mathematical operators. The product of [tex]\frac{1}{2x} -\frac{1}{4}[/tex] & [tex]5x^{2} -2x +6[/tex] is not equal to the product of [tex]\frac{1}{2x} -\frac{1}{4}[/tex] and [tex]5x^{2} -2x +6[/tex]

Since the original scale was 2 inches = 45 miles, the highway length on the original map was 8 inches * 45 miles/2 inches = 180 miles.

So, each of the 17 rest stops was spaced 180 miles / (17 - 1) = 10 miles apart on the highway.

With the new scale of 1 inch = 30 miles, each inch on the map represents 30 miles on the highway.

Answer: The tip is 20% of the cost including tax. Thus .20 * X=3.50.Divide both sides of the equation by .20..20 divided into .20 = 1, so “X” = 1.And 3.50 divided by .20 = 17.50 So X = 17.50, cost of the meal plus the tax.The tax is .07, so we know that 100% of the meal cost PLUS 7% of the meal cost is 107% of the meal cost. That is 1.07 * Meal without tax = 17.50. Divide 17.50 by 1.07 and you get 16.355. Round up to 16.36.Is that right? Let’s see:7% tax on meal at 16.36 is 16.36 * .07 = 1.1452.

To find the sales tax percentage, we need to determine how much of the total price was due to sales tax. To do this, we can subtract the price of the cupboard from the total price:

$92.82 - $85.78 = $7.04

So the sales tax was $7.04. We can then divide the sales tax by the price of the cupboard and multiply by 100% to find the sales tax rate as a percentage:

$7.04 / $85.78 * 100% = 8.2%

Rounding to the nearest tenth, the sales tax rate was 8.2%.

Answer:

8.2% (rounded to the nearest tenth)

Step-by-step explanation:

$92.82-$85.78= $7.04

100%= $85.78

1%= $85.78÷100

= $0.8578

$7.04÷$0.8578= 8.2% (rounded to the nearest tenth)

Answer:

Step-by-step explanation:

Since the balls are drawn with replacement, the probability of drawing a black ball on any single draw is 7/15. The probability of drawing 6 black balls in succession is the product of the probabilities of each individual draw being a black ball. Therefore, the probability is:

(7/15)^6 ≈ 0.019

Rounding to three decimal places, the probability is 0.019.

Answer:

0.003

Step-by-step explanation:

The probability of drawing a black ball on any given draw is 7/15, since there are 7 black balls and 15 total balls in the urn. Because the balls are replaced after each draw, the probability of drawing a black ball on each of the 6 successive draws is (7/15) x (7/15) x (7/15) x (7/15) x (7/15) x (7/15) = (7/15)^6.

Therefore, the probability of drawing 6 black balls in succession is:(7/15)^6 = 0.0028 (rounded to three decimal places)

So the probability that all 6 balls drawn from the urn are black is approximately 0.003.
