Answer:

B=28

Step-by-step explanation:

About 75% of the students' scores exceeded the score mentioned in the boxplot.

In a boxplot, the box represents the interquartile range (IQR), which contains the middle 50% of the data. The lower whisker extends to the minimum value within 1.5 times the IQR below the first quartile (Q1), and the upper whisker extends to the maximum value within 1.5 times the IQR above the third quartile (Q3).

Since the boxplot does not provide specific numerical values, we can infer that the mentioned score lies within the upper whisker, which represents the top 25% of the data. Therefore, about 75% of the students' scores exceeded this score.

It's important to note that without the actual values or specific percentiles, we can only estimate the percentage based on the visual representation of the boxplot. The exact percentage may vary depending on the scale and distribution of the data. To obtain a more precise estimate, additional information such as the quartiles or a histogram of the scores would be needed.

Answer:

Volume=21.195 cubic inch

Step-by-step explanation:

The volume of a cylinder varies jointly with its height and the square of the radius is expressed as

V∝hr^2

Introducing our constant of proportionality,K we have that

V =Khr^2

Given that A 7.85 cubic inch spice container is 2.5 inches tall and has a radius of 1 inch. We have that

V =Khr^2

7.85=K 2.5 X 1^2

K=7.85/2.5 x1

K=3.14

Given that another spice container is 3 inches tall with a radius of 1.5 inches, Volume=?

V =Khr^2

V=3.14 X 3 X 1.5^2

V=21.195 cubic inch

Answer:

70

Step-by-step explanation:

The formula for this question is

60/100 * x = 42

Look carefully at how this is written. You have so many pets (x) in the shop.

60 % of them are dogs. But that 60% we are told is also how many animals are dogs and that is 42.

So you have two facts meaning the same thing.

Multiply the equation by 100

100 * 60/100 *x = 42 * 100

60x = 4200    

Divide by 60

x = 4200/60

x = 70

The total number of animals was 70

Answer:

$43.75

Step-by-step explanation:

So you have: 35% discount

Total without discount: $125.00

Amount discounted: ?

So you have to make 35% into a number that you can multiply with $125. When you have a percentage you move the decimal two times to the front so you have 0.35 then you multiply;

125 x 0.35 = 43.75.

43.75 is the amount discounted, so you only have to pay 81.25. The equation for that would look like;

125 - 43.75 = 81.25

Hope that made sense!

It looks like the price of the item you want to purchase is $125.00, so the coupon will save you $ 43.75

Given data ,

To calculate how much the coupon will save you, you can multiply the price of the item by the percentage discount.

The price of the item is $125.00 and the coupon offers a 35% discount

The percentage of discount is given as = 35 %

35% of $125.00 can be calculated as:

On simplifying the equation , we get

(35/100) x $125.00 = $ 43.75

A = $ 43.75

Therefore, the coupon will save you $ 43.75 on your purchase

Hence , the coupon will save $ 43.75

The point of intersection with x - axis is (5/3,0) and the point of intersection with y - axis is (0,5).  

Any point on AB's perpendicular bisector, P(x,y), shall be considered. Then, PA = PB.

√(x-3)²+(y-6)² = √(x+3)²+(y-4)²

(x-3)²+(y-6)² = (x+3)²+(y-4)²

x² -6x+ 9 + y²- 12y + 36 = x² +6x+ 9 + y²- 8y + 16

12x + 4y -20 = 0

3x+ y-5 =0 ---(1)  

Consequently, 3x+y-5=0 is the equation for the perpendicular bisector of AB.

We know that the coordinates of any point on x-axis are of the form (x,0). In other words, any point on the x-axis has a y-coordinate of zero. Thus, if we enter y = 0 in (1), we get

3x -5 = 0

x = 5/3

Thus, the x-axis is cut by the perpendicular bisector of AB at (5/3, 0).

(ii) Any point's y-axis coordinates have the following format: (0,y). When we enter x = 0 in (1), we obtain

y − 5 = 0

⇒ y = 5

Thus, the y-axis is where the perpendicular bisector of AB intersects (0,5).

The sum of the arithmetic series 7.6+6.3+5 is 18.9. This can be found using the formula Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term. By substituting the given values, we get Sn = (3/2)(7.6 + 5) = 18.9.



To find the sum of a finite arithmetic series, we can use the formula Sn = (n/2)(a + l), where Sn is the sum, n is the number of terms, a is the first term, and l is the last term.

In the given arithmetic series 7.6+6.3+5, we have three terms: 7.6, 6.3, and 5. The first term (a) is 7.6 and the last term (l) is 5. Since we have three terms, the number of terms (n) is also 3.

Substituting these values into the formula, we get Sn = (3/2)(7.6 + 5) = (3/2)(12.6) = 18.9. Therefore, the sum of the finite arithmetic series 7.6+6.3+5 is 18.9.

In simpler terms, we can think of the sum of an arithmetic series as the average of the first and last term, multiplied by the number of terms. So in this case, we add 7.6 and 5 to get 12.6, and then divide it by 2 to get the average of 6.3. Finally, we multiply 6.3 by 3 (since we have three terms) to get the sum of 18.9.

The firm's output when marginal revenue is equal to zero is 1 million. Hence, the answer is option a. 1.

To find the firm's output when marginal revenue (MR) is equal to zero, we need to first understand the relationship between the demand curve and marginal revenue.

The marginal revenue (MR) is the change in total revenue resulting from producing and selling one additional unit of output. In this case, the total revenue (TR) is the product of quantity (Q) and price (P), so we have TR = QP.

To find the marginal revenue, we can take the derivative of the total revenue function with respect to quantity:

MR = d(TR)/dQ

Using the given demand curve Q = 2 - 0.01P, we can express price (P) in terms of quantity (Q) as P = 200 - 100Q (by rearranging the equation).

Substituting this price expression into the total revenue function, we have:

TR = QP = Q(200 - 100Q) = 200Q - 100Q^2

Now, we can find the marginal revenue by taking the derivative of the total revenue function with respect to quantity (Q):

MR = d(TR)/dQ = 200 - 200Q

To find the output level when MR is equal to zero, we set MR = 0 and solve for Q:

0 = 200 - 200Q

200Q = 200

Q = 200/200

Q = 1

Therefore, the firm's output when marginal revenue is equal to zero is 1 million. Hence, the answer is option a. 1.

Answer:

Step-by-step explanation:

a.  The marginal pdf f1(x) of X is 0

b. the conditional pdf f2(y∨x) is 0

c. The  P(Y>13∨X=x) for any x>13 is  0

a. To find the marginal pdf f1(x) of X, we integrate f(x,y) over y from 0 to x:

f1(x) = ∫ f(x,y) dy from 0 to x

= ∫ 15xy^2 dy from 0 to x

= 5x^4

So, f1(x) = 5x^4 for 0 ≤ x ≤ 1, and f1(x) = 0 otherwise.

b. To find the conditional pdf f2(y∨x), we use the formula:

f2(y∨x) = f(x,y) / f1(x)

So, we have:

f2(y∨x) = 15xy^2 / (5x^4) = 3y^2 / x^3 for 0 ≤ y ≤ x ≤ 1, and f2(y∨x) = 0 otherwise.

c. To find P(Y > 13 ∨ X = x) for any x > 0, we need to integrate the joint pdf f(x,y) over the region where y > 13 and x = x. This region is a triangular region with vertices at (x,13), (x,x), and (1,x). So, we have:

P(Y > 13 ∨ X = x) = ∫∫ f(x,y) dy dx over the triangular region

= ∫ x∫13^x 15xy^2 dy dx / (5x^4)

= ∫ x [(13x^3)/2 - (x^4)/4] dx / (5x^4)

= 15/8 - (13/8)x

So, P(Y > 13 ∨ X = x) = 15/8 - (13/8)x for 0 < x ≤ 1, and P(Y > 13 ∨ X = x) = 0 otherwise.

ASA congruence postulate says that if the two angles and the included side of a triangle are congruent to two angles and the included side of another triangle then the triangles are congruent. ABC ≅ XYZ

Congruent triangles are those with precisely the same dimensions and appearance. Congruent has the symbol. When the dimensions of one triangle's three sides and three angles match those of another triangle's three sides and three angles, the two triangles are said to be congruent.

Angle-Side-Angle congruence rule is referred to as ASA. Two triangles are said to be congruent according to this rule if any two angles and the side included between them of one triangle are equal to the corresponding angles and the included side of the other triangle. See if the two triangles given, ABC and XYZ, are congruent according to the ASA rule by looking at the image provided below.

According to the ASA criterion, ABC = XYZ because BC = YZ and B = Y and C = Z, respectively. Due to the fact that ABC = XYZ, the third angle (A) and the other two sides (A) of ABC must be equal to the equivalent angle (X) and sides of XYZ.

The probability that the gambler will win the bet is very low at only 0.83%.

The probability that the gambler will win the bet, we need to first determine the total number of possible outcomes or permutations for the top three finishers out of the six horses. This can be calculated using the formula for permutations:

P(6, 3) = 6! / (6-3)! = 6 x 5 x 4 = 120
This means that there are 120 possible ways that the top three finishers can be chosen out of the six horses. However, the gambler needs to pick the top three finishers in the correct order to win the bet. Therefore, there is only one correct outcome that will result in the gambler winning the bet.

The probability of the correct outcome happening is therefore:

1/120 = 0.0083 or approximately 0.83%
