18 pattern block trapezoids would be needed to create 3 hexagons.

Pattern block trapezoids are geometric shapes used for pattern block activities.

Each hexagon is typically made up of 6 pattern block trapezoids.

To determine the number of pattern block trapezoids required to create 3 hexagons, multiply the number of hexagons by the number of trapezoids in each hexagon.

Number of trapezoids = Number of hexagons × Number of trapezoids in each hexagon

                                    = 3 × 6

                                    = 18

Therefore, 18 pattern block trapezoids would be needed to create 3 hexagons.

Shandra is expected to select a pineapple chew about 56 times in the next 400 selections.

Based on the given results, Shandra selected a pineapple chew 8 times out of 57 selections. To estimate the expected number of times she would select a pineapple chew in the next 400 selections, we can use the proportion of pineapple chews selected in the first 57 selections:

The proportion of pineapple chews selected = 8/57

To estimate the expected number of pineapple chews in the next 400 selections, we can multiply the proportion by the total number of selections:

Expected number of pineapple chews in the next 400 selections = (8/57) x 400

expected number of pineapple chews in the next 400 selections = 56.14

Rounding to the nearest whole number, we would expect Shandra to select a pineapple chew about 56 times in the next 400 selections.

Step-by-step explanation:

Complementary angles add up to 90 degrees, so if one angle is known, the measure of its complement can be found by subtracting it from 90 degrees.

If <A is 16 degrees, then <B is 90 - 16 = 74 degrees.

If <A is 34 degrees, then <B is 90 - 34 = 56 degrees.

If <A is 46 degrees, then <B is 90 - 46 = 44 degrees.

If <A is 100 degrees, then <B is 90 - 100 = -10 degrees. However, angles can't be negative, so this solution is not valid.

Michael is now (B) 6 years old.

Let's start by defining variables for the current ages of Norman and Michael.

Let N be Norman's current age, and M be Michael's current age.

From the problem statement, we know that N = M + 12 (Norman is 12 years older than Michael).

We also know that in 6 years, Norman will be twice as old as Michael.

So we can set up the following equation:

N + 6 = 2(M + 6)

Substituting N = M + 12 into the equation, we get:

M + 12 + 6 = 2(M + 6)

Simplifying:

M + 18 = 2M + 12

M = 6

Therefore, Michael is currently 6 years old.

350 pounds of the meal should be added to the grain to produce a mixture that costs $1.10 per pound.

What is meant by addition?

In mathematics, addition is the process of fusing two or more integers. The numbers being added are known as addends, while the outcome of the addition process, or the final response, is known as the sum. It is one of the fundamental mathematical operations we employ on a daily basis. We add numbers in many different contexts.

Let the amount of meal mixed with the grain be 'x' pounds.

Now, Total price of the mixture = x*0.80 + 350*1.40 = (x+350)*1.10

350*(1.40 - 1.10) = x*(1.10 - 0.80)

350*0.3 = x*0.3

x = 350

Therefore, the amount of meal that should be added to the grain is 350 pounds.

If 10% of students who applied to university a were accepted, while university b accepted 50% of the applicants. The probability of being accepted to both universities is 0.05, or 5%.

The probability of being accepted at University A is 10%, which means the probability of not being accepted at University A is 90% (or 0.9). The probability of being accepted at University B is 50%, which means the probability of not being accepted at University B is 50% (or 0.5).

Since the events of being accepted at each university are independent of each other, we can use the multiplication rule of probability to find the probability of being accepted at both universities.

P(A and B) = P(A) x P(B)

where P(A and B) represents the probability of being accepted at both universities, P(A) represents the probability of being accepted at University A, and P(B) represents the probability of being accepted at University B.

Plugging in the values we have:

P(A and B) = 0.1 x 0.5 = 0.05

Therefore, the probability of being accepted to both universities is 0.05, or 5%. This means that there is a very low chance of being accepted at both universities, given the acceptance rates provided.

Hey there! Johnny Sins always here to help,

To find out what score Natasha needs to earn on her next test, we can use the following formula:

Average = (sum of all scores) / number of scores

Let's call the score Natasha needs to earn on her next test "x".

Her average so far is:

Average = (94 + 89 + 88 + 92 + 85) / 5 = 90

Her average after her next test will be:

Average = (94 + 89 + 88 + 92 + 85 + x) / 6

Now, we need to set this equal to 90% and solve for x:

90 = (94 + 89 + 88 + 92 + 85 + x) / 6

90 * 6 = (94 + 89 + 88 + 92 + 85 + x)

540 = (94 + 89 + 88 + 92 + 85 + x)

x = 540 - (94 + 89 + 88 + 92 + 85)

x = 540 - 448

x = 92

So, Natasha needs to earn a 92% on her next test to average at least 90%.

The ratio of pencils to pens can be calculated by dividing the number of pencils by the number of pens. In this case, the ratio of pencils to pens is 10/14.

A ratio is a way to compare two or more values or quantities. It is expressed as a fraction or as a colon-separated pair of numbers. The first number in the ratio represents the number of units of the first quantity, and the second number represents the number of units of the second quantity.

In the case of the ratio of pencils to pens, the first quantity is the number of pencils and the second quantity is the number of pens. To calculate the ratio, you divide the number of pencils by the number of pens. In this case, you would divide 10 by 14, which is equal to 10/14 or 5/7.

The ratio can be expressed as either a fraction or as a colon-separated pair of numbers. In this case, the ratio of pencils to pens is either 5/7 or 5:7.

The probability that they have dinner at the health food restaurant is 0.643.

To calculate the probability that the first one to arrive has dinner at the health-food restaurant given that they will wait only 20 minutes before leaving to eat elsewhere, we need to use conditional probability.

Let A be the event that the first one to arrive has dinner at the health-food restaurant, and let B be the event that the first one to arrive waits only 20 minutes before leaving to eat elsewhere.

We want to find P(A|B), the probability that A occurs given that B occurs.

We know that P(A) = 0.3, the probability that the first one to arrive has dinner at the health-food restaurant. We also know that P(B|A) = 0.6, the probability that the first one to arrive waits only 20 minutes before leaving to eat elsewhere given that they have dinner at the health-food restaurant.

To calculate P(B), the probability that the first one to arrive waits only 20 minutes before leaving to eat elsewhere, we need to use the law of total probability:

P(B) = P(B|A) x P(A) + P(B|A') x P(A')

where A' is the complement of A, i.e., the event that the first one to arrive does not have dinner at the health-food restaurant. We know that P(A') = 1 - P(A) = 1 - 0.3 = 0.7, and we are given that P(B|A') = 0.1, the probability that the first one to arrive waits only 20 minutes before leaving to eat elsewhere given that they do not have dinner at the health-food restaurant.

Therefore, we can calculate P(B) as:

P(B) = P(B|A) x P(A) + P(B|A') x P(A')

= 0.6 x 0.3 + 0.1 x 0.7

= 0.21 + 0.07

= 0.28

Finally, we can calculate P(A|B) using Bayes' theorem:

P(A|B) = P(B|A) x P(A) / P(B)

= 0.6 x 0.3 / 0.28

= 0.643

Therefore, the probability that the first one to arrive has dinner at the health-food restaurant given that they will wait only 20 minutes before leaving to eat elsewhere is approximately 0.643 or 64.3%.

A rule for the nth term of the sequence for which a = 30 and r= 1/2 the 5th term of the sequence is 1.875.

What is the geometric sequence?

A geometric sequence is often referred to as geometric progression or geometric series is defined as a sequential pattern of non-zero numbers in which the following number's value is a multiplication from the preceding number by another constant non-zero number.

The rule for the nth term of a geometric sequence is given by the formula:

aₙ  = a * r⁽ⁿ⁻¹⁾

where "a" is the first term in the sequence, "r" is the common ratio, and "n" is the position of the term in the sequence.

In this case, we have "a" = 30 and "r" = 1/2. Substituting these values into the formula, we get:

aₙ = 30 x (1/2)⁽ⁿ⁻¹⁾

This is the rule for the nth term of the sequence with the first term 30 and common ratio 1/2.

To find the nth term of the sequence, we simply plug in the value of "n" into the formula. For example, the 5th term of the sequence would be:

a₅ = 30 * (1/2)⁽⁵⁻¹⁾ = 30 * (1/2)⁴ = 30 * 1/16 = 1.875
