Can someone help me on 7-8

The number of observations strictly less than 24 is 7.

The five-number summary consists of the minimum value (13), the first quartile (Q1) or 25th percentile (24), the median or second quartile (Q2) or 50th percentile (38), the third quartile (Q3) or 75th percentile (51), and the maximum value (69).

Since Q1 represents the value below which 25% of the observations lie, and the five-number summary indicates that Q1 is 24, it means that 25% of the observations are less than or equal to 24.

Therefore, the number of observations strictly less than 24 is 25% of 33, which equals 7.

Answer:

C. 24 + 32

Step-by-step explanation:

Step 1 - Distribute

4 • 6 = 24

4 • 8 = 32

24 + 32

Answer:

B

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

here m = 4 , then

y = 4x + c ← is the partial equation

to find c substitute (- 3, - 1 ) into the partial equation

- 1 = - 12 + c ⇒ c = - 1 + 12 = 11

y = 4x + 11 ← equation of line

The law of mathematical logic that was used to derive the given conclusion is; Law of Syllogism

The law of syllogism is defined as a type of logical argument using deductive reasoning.

Now, In mathematical logic, the Law of Syllogism states that if the following two statements are true:

(1) If d , then e .

(2) If e , then f .

Then we can derive a third true statement:

(3) If d , then f .

Now, applying that law to our question, we see that;

The probability that a second call will not arrive in the next 20 seconds is approximately 0.2636 or 26.36%.

Poisson probability is a mathematical concept that describes the probability of a certain number of events occurring in a fixed interval of time or space, given a known average rate of occurrence. The Poisson probability distribution is named after French mathematician Siméon Denis Poisson, who introduced it in the early 19th century to model the occurrence of rare events, such as errors in counting or measurement, accidents, or phone calls.

The Poisson probability distribution is a discrete probability distribution that gives the probability of a certain number of events (x) occurring in a fixed interval (t), when the average rate of occurrence (λ) is known. The Poisson probability distribution assumes that the events occur independently and at a constant average rate over time or space. The formula for Poisson probability is:

P(x; λ) = (\(e^{-\lambda}\)) * λˣ) / x!

where:

P(x; λ) = the probability of x occurrences in a given interval, when the average rate is λ

e = a mathematical constant e (approximately 2.71828)

λ = it is the average rate of occurrence in the given interval

x = it is number of occurrences in the given interval

Given that calls for dial-in connections arrive at an average rate of four per minute and follow a Poisson distribution, we can use the Poisson probability formula to solve this problem. The Poisson probability formula is:

P(x; λ) =  (\(e^{-\lambda}\)) * λˣ) / x!

where:

P(x; λ) = the probability of x occurrences in a given interval, when the average rate is λ

e = a mathematical constant e (approximately 2.71828)

λ = the average rate of occurrence in the given interval

x = it is the number of occurrences in the given interval

In this problem, we are interested in finding the probability that a second call will not arrive in the next 20 seconds, given that a call has already arrived at the beginning of a one-minute interval. Since we are given the average rate of calls per minute, we need to adjust the interval to 20 seconds, which is 1/3 of a minute. Therefore, the average rate of calls per 20 seconds is:

λ = (4 calls/minute) * (1/3 minute) = 4/3 calls/20 seconds

Using the Poisson probability formula, we can calculate the probability of no calls arriving in the next 20 seconds:

P(0; 4/3) = ( \(e^{-4/3}\)* (4/3)⁰) / 0! = \(e^{-4/3}\) ≈ 0.2636

Answer: 6/r

Answer:

1) a = 8

2) q = 23

Step-by-step explanation:

1)

(a - 2) / 9 = 2 / 3

(a - 2) = (2 / 3) * 9

a - 2 = 18 / 3

a - 2 = 6

a = 6 + 2

a = 8

2)

(q + 2) / 5 = (2q - 11) / 7

q/5 + 2/5 = 2q/7 - 11/7

2/5 + 11/7 = 2q/7 - q/5

69/35 = 3q / 35

(69/35) * 35 = 3q

69 = 3q

69/3 = q

23 = q

Answer:

2/15

Step-by-step explanation:

Given that she have already read one-third of the book.

The fraction f of the book that will remain is;

f = 1 - 1/3 = 2/3

Then she finishes the book by reading the same amount each night for 5 nights

That implies she reads the remaining 2/3 of the book at equal rates for 5 nights.

Let x represent the fraction rate read per night;

5x = 2/3

Divide both sides by 5

x = 2/3 × 1/5

x = 2/15

Therefore, she reads 2/15 of the book every night for 5 nights.

What is the formula of a trapezoid?

The formula Area of trapezoid = 1/2 (a + b) h is used to determine the area of a trapezoid, where a and b are the bases (parallel sides) and h is the perpendicular height.

According to figure,

The portion of the base from the perpendicular to the right vertex is 6.2 cm, so we can label the remaining side as 3 + 6.2 = 9.2 cm.

shape is actually a trapezoid, with bases of 9.2 cm and 6.2 cm, and a height of 5 cm. The area of a trapezoid is given by the formula:

Area = (base1 + base2) * height / 2

Substituting the given values, we get:

Area = (9.2 + 6.2) * 5 / 2

Area = 15.4 * 5 / 2

Area = 38.5 cm²

Rounding to the nearest whole number, we get an area of 39 cm². Therefore, the answer is (D) 39 cm².

The table has been completed below.

An equation to represent the function P is P(x) = 4x.

In order to use the given linear function to complete the table, we would have to substitute each of the values of x (x-values) into the linear function and then evaluate as follows;

By substituting the given side lengths into the formula for the perimeter of a square, we have the following;

Perimeter of square, P(x) = 4x = 4(0) = A = 0 inches.

Perimeter of square, P(x) = 4x = 4(1) = B = 4 inches.

Perimeter of square, P(x) = 4x = 4(2) = C = 8 inches.

Perimeter of square, P(x) = 4x = 4(3) = D = 12 inches.

Perimeter of square, P(x) = 4x = 4(4) = E = 16 inches.

Perimeter of square, P(x) = 4x = 4(5) = F = 20 inches.

Perimeter of square, P(x) = 4x = 4(6) = G = 24 inches.
