A statement is not true about the dot plot to the right include the following: A. the French Club has a greater mean than the Spanish Club.

In Mathematics, a dot plot is a type of line plot that is typically used for the graphical representation of a data set above a number line, especially through the use of dots.

Mathematically, the mean for this set of scores can be calculated by using the following formula:

Mean = [F(x)]/n

Mean of French Club = 1/12(18 + (19 × 4) + (20 × 4) + (21 × 2) + 22)

Mean of French Club = 1/12(238)

Mean of French Club = 119/6 = 19.83.

Mean of Spanish Club = 1/12(18 + (19 × 2) + (20 × 3) + (21 × 3) + (22 × 3))

Mean of Spanish Club = 1/12(246)

Mean of Spanish Club = 123/6 = 20.5.

Therefore, 19.83 is less than 20.5.

Median of French Club = 20

Median of Spanish Club = (20 + 21)/2 = 20.5.

The answer is (iv) 150. This result can be obtained by applying the alternate segment theorem.

A circle is a shape with all points at an equal distance from the center. It has no sides or angles and is the only two-dimensional shape with this property. It is also the most basic of all shapes, and is found in nature in many forms, such as raindrops, the sun, and even the human pupil. Circles are often used in art, design, and architecture, and are sometimes even used to represent infinity.

This theorem states that if two chords of a circle intersect at right angles, then the angles in the alternate segments of the circle are equal. In this case, the alternate segments are APQ and CQP. Hence, ∠APQ + ∠CQP = 150°.

Answer:

Step-by-step explanation:

Let's first find the number of 12-year-olds and 13-year-olds in the band:

Let x be the number of 12-year-olds.

Then the number of 13-year-olds is 1.25x (125% of x).

The total number of students in the band is 100, so we know that x + 1.25x = 0.9(100).

Solving for x, we get x = 40, so there are 40 12-year-olds and 50 (1.25x) 13-year-olds.

The number of 14-year-olds is the remainder after we count the 12 and 13-year-olds:

The total number of students in the band is 100, and we know that 90% of them are 12 or 13 years old, so 10% are 14 years old.

10% of 100 is 10, so there are 10 14-year-olds.

Now we can find the portion of the band for each age group:

12-year olds: fraction = 40/100 = 2/5, percent = 40%

13-year olds: fraction = 50/100 = 1/2, percent = 50%

14-year olds: fraction = 10/100 = 1/10, percent = 10%

XPO's minimum tax credit carryover to 2019 is $20,500.

What is Algebraic expression ?

Algebraic expression can be defined as combination of variables and constants. An algebraic expression is a mathematical phrase that can contain numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division.

XPO's minimum tax credit from 2017 is $51,000. This means that they are allowed to reduce their 2018 tax liability by up to $51,000 using this credit.

Since their 2018 tax liability before any MTC carryover is $30,500, they have not used the entire minimum tax credit for 2017. Therefore, they can carry over the remaining credit to 2019.

To calculate the minimum tax credit carryover to 2019, we need to subtract the amount of the minimum tax credit that XPO used in 2018 from the total minimum tax credit of $51,000:

Minimum tax credit carryover = $51,000 - $30,500 = $20,500

Therefore, XPO's minimum tax credit carryover to 2019 is $20,500.

Answer: 545,884,646.36 ft3.

Step-by-step explanation:

The volume of the cylinder is calculated using the formula V=πr2h, where r is the radius of the cylinder and h is the height. The radius of the cylinder can be calculated by dividing the diameter (125 times the height) by 2.

Therefore, the radius = (125 * 1934) / 2 = 118,550 / 2 = 59,275 ft

Plugging in the values of radius and height into the formula, the volume of the cylinder is V = 3.14 * (59,275)2 * 1934 = 545,884,646.36 ft3

Rounding to the nearest hundredth, the volume of the cylinder is 545,884,646.36 ft3.

Answer: b = 8

Step-by-step explanation:

From the equation, we can see that x = 0 is one of the solutions. This means that the remaining solutions must add up to 5.

Let's factor the equation and set each factor equal to zero:

x²(x+3)(x - b) = 0

x = 0 or x + 3 = 0 or x - b = 0

Solving for x in each case, we get:

x = 0 or x = -3 or x = b

Since the sum of the solutions is 5, we can write:

0 + (-3) + b = 5

Simplifying, we get:

b - 3 = 5

Adding 3 to both sides, we get:

b = 8

Therefore, the value of b is 8.

Let d be the distance in miles from the airport that a plane should begin descending. According to the problem statement, we can write the equation:

d/3 = 10

To solve for d, we can isolate it by multiplying both sides of the equation by 3:

Therefore, the pilot should begin descending when the plane is 30 miles from the airport.

The given investment realized a loss of $3.75 with 31.25% decrease.

The amount made by selling a product, which should be greater than the product's cost price, is generally referred to as the profit. It is the profit generated by all business activities. In other words, a product is deemed to have made a profit if its selling price (SP) exceeds its cost price (CP). It explains the financial gain realised when the revenue from a company activity outpaces the costs, like as taxes and expenses, involved in maintaining a business activity.

Given : Purchase Price: $12.00

            Selling Price: $8.25

Since the purchase price is more than the selling prize, So the investment has been sold at a loss.

The loss on investment = Purchasing price - Selling price

                                       = $ 12 - 8.25

(i) N(t) = No e^(-0.088t) (ii) approximately 323.3 g of the substance(iii) the rate of change of the amount of the substance after 3 days is approximately -28.4 g/day.(iv) approximately 7.88 days.

The rate of change can be positive, indicating an increase in the value of the variable, or negative, indicating a decrease. It can also be constant, indicating a steady increase or decrease, or it can vary over time, indicating a more complex pattern of change. Understanding the rate of change of a variable is important in many fields, including engineering, economics, and finance, among others.

(i) Since the decay rate is given by -0.088 per day, the exponential function that models the decay is:

N(t) = No e^(-0.088t)

where No is the initial amount of the substance present at t=0.

(ii) If 400g of the substance is present at t=0, then we have No = 400. Substituting this value into the exponential function, we get:

N(t) = 400 e^(-0.088t)

To find how much will remain after 3 days, we need to evaluate N(3):

N(3) = 400 e^(-0.088*3) ≈ 323.3 g

Therefore, approximately 323.3 g of the substance will remain after 3 days.

(iii) The rate of change of the amount of the substance after t days is given by:

dN/dt = -0.088N

To find the rate of change after 3 days, we need to evaluate dN/dt at t=3:

dN/dt | t=3 = -0.088N(3) = -0.088(323.3) ≈ -28.4 g/day

Therefore, the rate of change of the amount of the substance after 3 days is approximately -28.4 g/day.

(iv) We want to find the value of t such that half of the original 400 g of the substance remains. In other words, we want to solve the equation:

N(t) = 200

Substituting No = 400 into the exponential function, we get:

400 e^(-0.088t) = 200

Dividing both sides by 400, we get:

e^(-0.088t) = 0.5

Taking the natural logarithm of both sides, we get:

ln(e^(-0.088t)) = ln(0.5)

Simplifying, we get:

-0.088t = ln(0.5)

Solving for t, we get:

t ≈ 7.88 days

Therefore, after approximately 7.88 days, half of the original 400 g of the substance will remain.

Answer: The numerator is the percentage change in quantity demanded, which is (Q2 - Q1)/[(Q2 + Q1)/2] = (4500 - 5000)/[(4500 + 5000)/2] = -0.1818

The denominator is the percentage change in price, which is (P2 - P1)/[(P2 + P1)/2] = (3500 - 3000)/[(3500 + 3000)/2] = 0.1429

The numerator divided by the denominator is -0.1818/0.1429 = -1.2727

The price elasticity of demand is greater than 1 in absolute value, which means the demand is elastic.

Using the midpoint formula, we can calculate the price elasticity of demand as:

[(Q2 - Q1)/((Q1 + Q2)/2)] / [(P2 - P1)/((P1 + P2)/2)]

Substituting the given values, we get:

[(-500)/((5000 + 4500)/2)] / [(3500 - 3000)/((3500 + 3000)/2)]

Simplifying, we get:

-0.1818 / 0.1429 = -1.2727

Since the price elasticity of demand is greater than 1 in absolute value, the demand is elastic. This means that the percentage change in quantity demanded is greater than the percentage change in price, and the university can expect a relatively large decrease in enrollment due to the tuition increase.
