Answer:

Step-by-step explanation:

The given sequence is an arithmetic sequence with a common difference of 4. The 77th term of the sequence is the 77th term of the arithmetic sequence, which is given by the formula:

a_n = a_1 + (n - 1) * d

where a_n is the nth term of the sequence, a_1 is the first term of the sequence, and d is the common difference. Substituting the values for a_1, n, and d into this formula, we get:

a_77 = -8 + (77 - 1) * 4

= -8 + 76 * 4

= -8 + 304

= 296

Therefore, the 77th term of the sequence is 296.

Answer: b=2/5

Step-by-step explanation:

Step 1: Cross-multiply.

2b−1/2 = b−1/6

(2b−1)*(6)=(b−1)*(2)

12b−6=2b−2

Step 2: Subtract 2b from both sides.

12b−6−2b=2b−2−2b

10b−6=−2

Step 3: Add 6 to both sides.

10b−6+6=−2+6

10b=4

Step 4: Divide both sides by 10.

10b/10 = 4/10

b = 2/5

Answer:

3

Step-by-step explanation:

The factorial of a number n is the product of all the positive integers from 1 to n. In other words, n! = 1 * 2 * 3 * ... * n. For example, the factorial of 5 is 5! = 1 * 2 * 3 * 4 * 5 = 120.

In this case, we are asked to find the value of the expression 10!/(4!7!). To do this, we first need to evaluate the factorials in the numerator and denominator of the expression. Since 10! = 1 * 2 * 3 * ... * 10, we have:

10! = 1 * 2 * 3 * 4 * 5 * 6 * 7 * 8 * 9 * 10 = 3628800

Similarly, since 4! = 1 * 2 * 3 * 4 and 7! = 1 * 2 * 3 * 4 * 5 * 6 * 7, we have:

4! = 1 * 2 * 3 * 4 = 24

7! = 1 * 2 * 3 * 4 * 5 * 6 * 7 = 5040

Now that we have evaluated the factorials in the expression, we can plug these values into the expression and evaluate it:

10!/(4!7!) = 3628800 / (24 * 5040) = 3628800 / 120960 = 3

Therefore, the value of the expression 10!/(4!7!) is 3.

Note: It is important to remember that the factorial of 0 is defined to be 1, so 0! = 1. This means that any expression involving 0! can be simplified by replacing 0! with 1. For example, the expression 10!/(4!7!0!) can be simplified as follows:

10!/(4!7!0!) = 10!/(4!7!1) = 10!/(4!7) = 10!/(24 * 7) = 10!/168 = 3628800/168 = 3

This is the same result we obtained above using the factorials of 10, 4, and 7.

The value of the given expression is 30.

An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.

The given expression is 10!/(4!7!).

Now, (10×9×8×7!)/(4!7!)

= (10×9×8)/(4×3×2×1)

= 5×3×2

= 30

Therefore, the value of the given expression is 30.

The equation of the line n parallel to line m will be y = 3/2x - 9. The correct option is A.

An equation of the line is defined as a linear equation having a degree of one. The equation of the line contains two variables x and y. And the third parameter is the slope of the line which represents the elevation of the line.

The general form of the equation of the line:-

y = mx + c

The total weight of Mrs. Portillo's cat and the dog is 34 kilograms.  

The mathematical operations known as operators focus on particular activities, such as adding, taking away, adding multiple times and dividing equally, etc.

The four fundamental operations in Maths are

1. Addition

2. Subtracting

3. Multiplications

4. Divisions

Here we use Addition to solve the problem

Here we have

Cat's weight = 6 kilograms

Her dog weighs 22 kilograms more than her cat

Weight of dog = Cat's weight + 22 kilograms

= 6 kilograms + 22 kilograms

= 28 kilograms

Total weight of Mrs. Portillo's cat and dog = 6 + 28 = 34 kilograms

The value of x is 27 in the given figure.

An angle is formed when two straight lines or rays meet at a common endpoint.

We need to find the value of x.

The given two angles are (4x+7) and 5(x-4).

The two angles are opposite angles so the two angles are equal.

Let us equate 4(x+7) and 5(x-4).

4x+7=5(x-4).

Apply distributive property on RHS

4x+7=5x-20

4x-5x=-20-7

-x=-27

Multiply both sides by minus

x=27.

When a sample of size 25 is taken from a population with a mean of 120 and a standard deviation of 10,The expected distance between the sample mean and the population mean is 2.5.

The mean of a population is the average value of all the data points, while the standard deviation is a measure of how spread out the data points are. When a sample of size 25 is taken from a population with a mean of 120 and a standard deviation of 10, the expected distance between the sample mean and the population mean is 2.5. This is because the standard deviation of the sample mean is equal to the population standard deviation divided by the square root of the sample size. In this case, the standard deviation of the sample mean would be 10/5 = 2, and the expected distance between the sample mean and the population mean would be 2 x 2.5 = 2.5.

Standard deviation of the sample mean = Population standard deviation / √ Sample size

= 10 / √25

= 10 / 5

= 2

Expected distance between the sample mean and the population mean = 2 x 2.5

= 2.5

The right-angled triangle have angle B = 40°, side c = 20.9 and b = 13.4 approximately to the nearest tenth.

We shall use the trigonometric ratios of sine and cosine of the angle 50° to get the length of the sides and apply the rule of the sum of interior angles of a triangle to get the angle B.

sin50° = opposite/hypotenuse

sin50° = 16/c

c = 16/(sin50°) {by cross multiplication}

c = 20.9

cos50° = adjacent/hypotenuse

cos50° = b/20.9 {by cross multiplication}

b = 20.9 × cos50°

b = 13.4

The sum of interior angles of a triangle is equal to 180° so;

angle B = 180° - (90° + 50°)

angle B = 180° - 140°

angle B = 40°

Therefore, by application of trigonometric ratios sine and cosine, we have the sides of the right-angled triangle b = 13.4, c = 20.9, and the angle B = 40°.

Answer:

To solve this system, we need to find the values of x and y that make both equations true at the same time.

Let's start by solving the first equation for y:

|2х - бу = 1

2х - бу = 1

-2х + бу = -1

бу = 1 - 2х

y = (1 - 2х)/б

Now let's substitute this expression for y into the second equation:

x - (1 - 2х)/б = 1

x - 1 + 2х/б = 1

3х/б = 0

x = 0

Substituting this value for x back into the first equation, we get:

y = (1 - 2*0)/б = 1/б

So the solution to the system of equations is x = 0 and y = 1/б.

What is probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

A probability is a numerical representation of the likelihood or chance that a specific event will take place. Both proportions ranging from 0 to 1 and percentages ranging from 0% to 100% can be used to describe probabilities.

The given information is expressed as

Side effect no side effect total

Adult 7 43 50

Children 22 28 50

Total 29 71 100

Probability is expressed as

Number of favorable outcomes/number of total outcomes

For the probability that an adult has side effects,

Total number of outcomes = 50

Number of favorable outcomes = 7

Probability that an adult has side effects = 7/50 = 0.14

For the probability that a child has side effects,

Total number of outcomes = 50

Number of favorable outcomes = 22

Probability that an adult has side effects = 22/50 = 0.44
