The solution of the inequality 3x < 13 is x < 4.33.

None of the given option is correct.

In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.

The correct option is (b) -30±15.3. To calculate the confidence interval, we can use the formula: (μ₂₉ − μ₂₁) ± t* (SE).

t is the t-value with 8 degrees of freedom and a 99% confidence level, and SE is the standard error of the difference between the means:

SE = √[(s₁²/n₁) + (s₂²/n₂)]

Plugging in the given values, we get:

SE = √[(8²/9) + (13²/9)] = 6.02

The t-value for 8 degrees of freedom and a 99% confidence level is 3.355.

So, the confidence interval is:

(78-48) ± 3.355*6.02 = 30 ± 15.3

Therefore, the 99% confidence interval for μ₂₉ − μ₂₁ is -30±15.3.

The bearing from the phone to the transmitter is approximately 31 degrees to the east of the north direction.

To determine the bearing from the phone to the transmitter, we can use trigonometry.

The bearing is typically measured clockwise from the north direction.

Given that the transmitter is 13 km west and 21 km south of the phone, we can form a right triangle with the phone as the vertex angle.

The side opposite to the vertex angle represents the north-south direction, and the side adjacent to the vertex angle represents the east-west direction.

Using the tangent function, we can calculate the angle:

tangent(angle) = (opposite side) / (adjacent side)

tangent(angle) = 21 km / 13 km

Taking the inverse tangent (arctan) of both sides, we find:

angle = arctan(21 km / 13 km)

Evaluating this using a calculator, we find the angle to be approximately 58.57 degrees.

However, since the bearing is measured clockwise from the north, we need to subtract this angle from 90 degrees (which represents the north direction) to obtain the bearing:

bearing = 90 degrees - 58.57 degrees

Calculating this, we find the bearing to be approximately 31.43 degrees.

Answer:

the slope intercept form is   y = (1/2)x - 1

Step-by-step explanation:

The slope-intercept form is, y = mx + b

We see from looking at the graph that,

at x = 0, y = -1

So, from this we find that b = -1

at x = 2, y = 0,

now, we find the slope m,

using,

\(m = \frac{y_{2} -y_1}{x_2-x_1}\)

Using x_2 = 2, y_2 = 0,

x_1 = 0, y_1 = -1, we get,

m = (0-(-1))/(2-0)

m = 1/2

So, the slope intercept form is,

y = (1/2)x - 1

The answer is

J) 334.06

Step-by-step explanation:

We know the rate is 1.5 inch an hour

So 1.5*2.54 is 3.81

Now 3.81 cm every hour

24 hours a day

3.81*24=91.44

Now 91.44 cm A day

1 Year or 365 days

91.44*365= 33375.6cm a year

now we also need to add the extra 12 inches in the beginning

12*2.54=30.48cm

Now add those 2

33375.6+30.48= 33406.08

The average rate of change of the function f(x) = √(x+4) over the interval 2 ≤ x ≤ 6 is approximately 0.29 to the nearest hundredth.

To find the average rate of change of the function f(x) = √(x+4) over the interval 2 ≤ x ≤ 6, we need to calculate the change in the function divided by the change in the input variable over that interval.

The change in the function between x = 2 and x = 6 is:

f(6) - f(2) = √(6+4) - √(2+4) = √10 - √6

The change in the input variable between x = 2 and x = 6 is:

6 - 2 = 4

So, the average rate of change of the function over the interval 2 ≤ x ≤ 6 is:

(√10 - √6) / 4

To approximate the answer to the nearest hundredth, we can use a calculator or perform long division to get:

(√10 - √6) / 4 ≈ 0.29

P(A) = 0.3

Step-by-step explanation:

independent event:

P(A|B) = P(A) = 0.3

The value of P(A) is equal to 0.3 to the nearest tenth.

When one event's occurrence or non-occurrence doesn't affect the occurrence or non-occurrence of another event, then such events are called independent events. Comparing it with the chain rule will give

\(P(A|B) = P(A)\\P(B|A) = P(B)\)

It is showing that whether one occurred or not, the other one doesn't care about it (independence).

Given that A and B are independent events, A and C are dependent. P(A|B) = 0.3,

P(A|C) = 0.2.

We know that for the independent event:

P(A|B) = P(A)

The first two terms of the sequence are 3 and 12 and the 3rd and 4th terms are 25 and 42.

The 3rd and 4th terms of the sequence is determined from second level difference as shown below;

(c - b) - (b - a) = 4  ----(1)

(d - c) - (c - b) = 4 ---- (2)

from (1);

(c - 12) - (12 - 3) = 4

(c - 12) - (9) = 4

c - 21 = 4

c = 25

from (2);

(d - 25) - (25 - 12) = 4

d - 38 = 4

d = 42

The sequence = 3, 12, 25, 42

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

We know that,

An arithmetic sequence is a sequence of integers with its adjacent terms differing with one common difference.

The explicit formula for any arithmetic series is given by the formula,

a_n = a_1 + (n-1)d

where d is the difference and a₁ is the first term of the sequence.

The major distinction between recursive and explicit formulas is that a recursive formula returns the value of a particular term depending on the preceding term, whereas an explicit formula returns the value of a given term based on its location.

When the value of the first term and the common difference is known then an explicit formula is used, while the recursive formula will be used when the value of the previous value is known and the value of the common difference is known.

Given:

A regular pentagon with a side length of 11.8 inches and a dotted line from center to middle of side of 8.1 inches.

To find:

The area of the regular polygon.

Solution:

We have,

Side length = 11.8 inches

Length of Apothem = 8.1 inches

Area of a triangle is

\(Area=\dfrac{1}{2}\times base\times height\)

A regular pentagon has 5 equal sides and equal interior angles. The lines from the center to the vertices divide the pentagon in 5 equal triangle.

Area of one triangle is

\(A_1=\dfrac{1}{2}\times \text{Side length}\times \text{Apothem}\)

\(A_1=\dfrac{1}{2}\times 11.8\times 8.1\)

\(A_1=47.79\)

Area of five equal triangle is

\(A=5\times A_1\)

\(A=5\times 47.79\)

\(A=238.95\)

So, the area of the pentagon is 238.95 square inches.

Therefore, the correct option is B.
