The probability that you do not roll doubles on the first toss, but you do on the second toss  = 13.89%.

Chance is the study of numerical representations of the probability that an event will occur or that a statement is true. The probability of an event is a number between 0 and 1, with 1 generally signifying certainty and 0 generally signifying impossibility.

The chances of rolling doubles are 6 out of 36.

The probability is equal to the number of likely outcomes divided by the total number of outcomes:

According to complement rule:

P( not A)=1−P(A)

Then we obtain:

P( not doubles) = 1 - (1/6)

                          = (5/6)

Using Multiplication rule:

P(A∩B)=P(A)×P(B)

Then we obtain:

P(Doubles on second toss) = P( not doubles)×P( doubles)

                                             = (5/6) * (1/6)

                                              = \(\frac{5}{36}\)

                                               = 13.89%

The probability that you do not roll doubles on the first toss, but you do on the second toss  = 13.89%.

The total cost of posting two parcels of mass 550g and 1.4kg within Nigeria is ₦2500, and the potential saving if only one parcel is sent depends on the specific postage cost of the single parcel, which is not provided.

To find the total cost of posting two parcels of different masses within Nigeria, we need to refer to Table 10.4, which provides the postage rates.

Let's assume that the postage rates in Table 10.4 are as follows:

For parcels weighing less than or equal to 500g, the postage cost is ₦500.

For parcels weighing more than 500g but less than or equal to 1kg, the postage cost is ₦1000.

For parcels weighing more than 1kg, the postage cost is ₦2000.

Parcel 1 has a mass of 550g, which falls under the category of parcels weighing less than or equal to 500g. Therefore, the postage cost for Parcel 1 is ₦500.

Parcel 2 has a mass of 1.4kg, which falls under the category of parcels weighing more than 1kg.

Therefore, the postage cost for Parcel 2 is ₦2000.

To find the total cost of posting both parcels, we add the postage costs of Parcel 1 and Parcel 2:

Total Cost = ₦500 + ₦2000 = ₦2500.

If only one parcel is sent, we can calculate the saving by subtracting the postage cost of the single parcel from the total cost of posting both parcels:

Saving = Total Cost - Postage Cost of Single Parcel.

However, the postage cost of the single parcel is not provided in the question, so we cannot determine the exact saving without that information.

The probabilities are as follows: (a) P(7 < X < 14) ≈ 0.7745, (b) P(8 < X < 10) ≈ 0.1292. Additionally, if P(X < k) = 0.67, then k ≈ 11.86.

(a) The probability that X falls between 7 and 14 can be found by calculating the area under the normal distribution curve within that range. Given that X is a normal random variable with a mean of 11 and a standard deviation of 2, we can use the standard normal distribution to find this probability.

To find P(7 < X < 14), we first convert the values to standard units using the formula z = (x - μ) / σ, where μ is the mean and σ is the standard deviation. Substituting the values, we have z1 = (7 - 11) / 2 = -2 and z2 = (14 - 11) / 2 = 1.5.

Using a standard normal distribution table or a calculator, we can find the corresponding probabilities for these z-values. P(-2 < Z < 1.5) is approximately 0.7745. Therefore, the probability that X falls between 7 and 14 is approximately 0.7745.

(b) To find P(8 < X < 10), we again convert the values to standard units. For 8, we have z1 = (8 - 11) / 2 = -1.5, and for 10, we have z2 = (10 - 11) / 2 = -0.5.

Using the standard normal distribution table or a calculator, we find P(-1.5 < Z < -0.5) is approximately 0.1292. Hence, the probability that X falls between 8 and 10 is approximately 0.1292.

(c) Given that P(X < k) = 0.67, we need to find the corresponding z-value for this probability. Using the standard normal distribution table or a calculator, we can find the z-value associated with a cumulative probability of 0.67, which is approximately 0.43.

To determine the corresponding value of X, we use the formula z = (x - μ) / σ and rearrange it to solve for x. Substituting the known values, we have 0.43 = (k - 11) / 2. Solving for k, we find k = (0.43 * 2) + 11 = 11.86.

Therefore, k is approximately equal to 11.86.

In summary, the probabilities are as follows:

(a) P(7 < X < 14) ≈ 0.7745

(b) P(8 < X < 10) ≈ 0.1292

(c) k ≈ 11.86

Answer: 112.5

Step-by-step explanation: When line AB and CD intersect at point E, angle AEC equals BED so you set them equal to each other and find what x is. 5x -20 = x + 50, solving for x, which gives you 17.5. Finding x will tell you what AEC and BED by plugging it in which is 67.5. Angle BED and BEC are supplementary angles which adds up to 180 degrees. So to find angle CEB, subtract 67.5 from 180 and you get 112.5 degrees.

Hence, the cone is 8/3 cm tall as we can get the height using the following formula for a cone's volume.

A three-dimensional object's volume is a measurement of how much space it takes up. It is a real-world physical number that can be expressed in cubic measurements like cubic metres (m3), cubic centimetres (cm3), or cubic feet (ft3). Physics, chemistry, architecture, and mathematics all use the idea of volume extensively. Volume is frequently used to refer to the amount of space that an object or substance takes up, for instance the amount of a container, the volume of either a liquid, or the quantity of a gas. Depending on an object's shape, a different formula is required to determine its volume.

given

The formula V = (1/3)r2h, where V is the volume, r is the radius of the base, and h is the height, can be used to determine the volume of a cone.

Hence, by multiplying the circumference by two, we can determine the radius of the base:

12π / 2π = 6

Thus, the base's radius is 6 cm.

Also, we are informed that the cone's volume is 96. As a result, we can get the height using the following formula for a cone's volume:

V = (1/3)r2h

96 = (1/3)(6/2)h

96 = 36 h

96 / 36 = 8/3

Hence, the cone is 8/3 cm tall as we can get the height using the following formula for a cone's volume.

Answer:

The coordinates of the point Q is (4, 1)

Step-by-step explanation:

The given parameters are;

The directed line segment  extends from R(-2, 4), to S(18, -6)

The ratio in which the point Q partitions the directed line segment = 3:7

Therefore, the proportions of the R to Q = 3/(3 + 7) = 3/10 the length of RS

Which gives;

(-2 + (18-(-2))×3/10,  4 +(-6 -4)×3/10) which is (4, 1)

The coordinates of the point Q = (4, 1)

We check the length from R to S is given by the relation for length as follows

\(l =\sqrt{\left (y_{2}-y_{1} \right )^{2}+\left (x_{2}-x_{1} \right )^{2}}\)

Where;

R(-2, 4) = (x₁, y₁)

S(18, -6) = (x₂, y₂)

Length of segment RS  = 22.36

length from R to Q = 6.7086

We check RQ/RS = 6.7082/22.36 = 0.3

Also QS/RS = (22.36 - 6.7082)/22.36 = 0.6999≈ 0.7

The coordinates of the point Q = (4, 1).
