3.76 many times large is 7.9 x 10⁴ than 2.1 x 10³. This can be solved using scientific notation method.

A method of writing numbers that combines a power of 10 with a number between 1 and 10. Using scientific notation, one may express extremely big or extremely small values. Once a number between 1 and 10 has been multiplied by such a power of 10, it is then expressed in scientific notation. For instance, 6.9 × 10⁸ can be used to represent the number 690,000,000.

The main goal of scientific notation is to simplify computations using numbers that are abnormally big or tiny. When a number is written in scientific notation, all of the digits are important since zeros are no longer utilized to set the decimal point.

For: 7.9 x 10⁴

= (79/10) x 10⁴

= 79 x 10³

on the other hand for: 2.1 x 10³

Thus, 3.76 many times large is 7.9 x 10⁴ than 2.1 x 10³.

Step-by-step explanation:

x = my number

3(x + 21)

multiply sum of 21 and my number by 3

=

(2/3)x + 84

84 more than 2/3 of my number

3(x + 21) = (2/3)x + 84

9(x + 21) = 2x + 3×84 = 2x + 252

9x + 189 = 2x + 252

7x + 189 = 252

7x = 63

x = 9

my number is 9.

Answer: In an experiment, if the probability that event A occurs is 0.2 and the probability that event B occurs is 0.5, then the probability that either event A or event B (or both) will occur is the sum of their individual probabilities, which is 0.2 + 0.5 = 0.7.

It should be noted that the sum of the individual probabilities of two events is less than or equal to 1. If the sum of the probabilities is greater than 1, it means that the events are not mutually exclusive and that means that they can happen at the same time.

It's important to mention that the above answer is based on the assumption that events A and B are mutually exclusive events, which means that they cannot happen at the same time. If they are not mutually exclusive, the probability of both occurring at the same time would have to be calculated using the formula P(A and B) = P(A) * P(B|A) where P(A) is the probability of event A occurring and P(B|A) is the probability of event B occurring given that event A has already occurred.

16 is the number  gives a result of −4 when 8 is subtracted from the quotient of the number and 4.

A division is a process of splitting a specific amount into equal parts.

If it gives a result of -4 then our equation will have ___ = -4

If we subtract 8 from the quotient of a number and 4 we have  x/4 - 8

Our equation is:

x/4 - 8 = -4    

Add 8 to both sides

x/4=-4+8

x/4=4

Multiply both sides by 4

x=16.

14) Probability that exactly 5 of the students will graduate is 0.1636.

15) Probability that atleast 8 of the students will graduate is 0.2405.

We have , In a college,

The freshmen graduate enters = 64%

Probability of sucess , p = 64% = 0.64

Probability of failure , q = 1 - 0.64 = 0.36

Randomly selected entering = 10 , i.e, n = 10.

This follows a Binomial probability distribution with the parameters, n = 10 and p = 0.64.

Using Binomial probability formula,

P(X = x) = ⁿCₖ pᵏ (1 - p)ⁿ⁻ᵏ

(14) Probability that exactly 5 of the students will graduate = P(x = 5),

P( x = 5) = ¹⁰C ₅ (0.64⁵) (0.36⁵)

= 0.1636

15) Probability that at least 8 of the students will graduate, P(x ≥8) = P(X= 8) + P(X= 9) + P(X= 10)

= ¹⁰C₈ 0.64⁸ 0.36² + ¹⁰C₉ 0.64⁹ 0.36¹ + ¹⁰C₁₀ 0.64¹⁰ 0.36⁰ = 0.2405

The statement (c) describes that the graph of f is shifted 5 units down to create the graph of g. The solution has been obtained using the concept of vertical translation.

What is translation?

Translation is the act of moving a shape or a figure from one position to another. It is classified into two types:

Now, for a function f(x) we define a vertical translation of N units as:

g(x) = f(x) + N

If N is positive, the translation is upwards.

if N is negative, the translation is downwards.

We are given g(x) = f(x) - 5

This shows that N is negative and therefore, there is translation of 5 units downwards.

     (x-2)² + ( y + 1)² = 34 is the equation of the circle in standard form.

What is the short definition of a circle?

To put it simply, a circle is a spherical shape without any edges or line segments. In terms of geometry, it has the shape of a closed curve.

                                             The circle's points are set apart from the center by a predetermined amount.

The endpoints of the diameter (7,−4) and (−3,2)

the center of the circle is the midpoint of the diameter.

So, the coordinates of the center  

                      (h,k) = ( 7 + (-3)/2  , -4 +2/2)

                                = ( 4/2 , -1 )

                                 = ( 2 , -1 )

the radius of the circle is just half of the length of the diameter.

So,                 r = 1/2√(-3 -7 )² + ( 2 - (-4))²

                        = 1/2√(10)²  + ( 2 +4 )²

                        = 1/2√100 + 36

                        = 1/2√136

                         = √136/2

                        = 2√34/2

                         = √34

substitute the values of h, k, and r into the standard equation of the circle

                       ( x-h)² + ( y-k)² = r²

                      ( x - 2)² + ( y -(-1))² = (√34)²

                       (x-2)² + ( y + 1)² = 34

The value of the evaluated iterated integral is = 0.002

As per the given data the iterated integral is, [tex]I[/tex] = [tex]\int\limits^1_0[/tex] [tex]\int\limits^s_0[/tex] cos ([tex]s^{6}[/tex] ) [tex]dt ds[/tex]

Here we have to evaluate the given iterated integral.

The definite integral of a real-valued function f(x) with respect to a real variable x on an interval [a, b] is expressed as,

[tex]\int\limits^a_b f({x} )\, dx[/tex] = f(b) - f(a)

Where,

a = Lower limit

b = Upper limit

f(x) = Integrand

dx = Integrating agent

Thus, [tex]\int\limits^_[/tex] ab f(x) dx is read as the definite integral of f(x) with respect to d x from a to b.

Indefinite integrals are implemented when the boundaries of the integrand are not specified.

[tex]I[/tex] = [tex]\int\limits^1_0[/tex] [tex]\int\limits^s_0[/tex] cos ([tex]s^{6}[/tex] ) [tex]dt ds[/tex]

Integrate the given iterated integral.

We get:

= [tex]\int\limits^1_0[/tex] cos ([tex]s^{6}[/tex] ) ([tex]\int\limits^5_0dt[/tex] ) ds

= [tex]\int\limits^1_0[/tex] cos ([tex]s^{6}[/tex] ) [t][tex]0 to s^{5}[/tex] ds

= [tex]\int\limits^1_0[/tex] cos ([tex]s^{6}[/tex] ) [tex](s^{5} -0)[/tex] ds

= [tex]\int\limits^1_0[/tex] [tex]s^{5}[/tex]cos ([tex]s^{6}[/tex] )ds

Then,

[tex]s^{6}[/tex] = t       when s = 0

[tex]\frac{dt}{ds}[/tex] = 6[tex]s^{5}[/tex]         t = 0  

[tex]\frac{dt}{6}[/tex] = [tex]s^{5}[/tex]  ds      when s = 1.....   t = 1

Replace the assumed terms.

Then we get:

[tex]I[/tex] = [tex]\int\limits^1_0[/tex] cos(t) [tex]\frac{dt}{6}[/tex]

[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [tex]\int\limits^1_0[/tex] cos(t) dt

[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [sin(t)][tex]0to1[/tex]

[tex]I[/tex] = [tex]\frac{1}{6}[/tex] [ sin(1) - sin(0) ]

[tex]I[/tex] = [tex]\frac{sin(1)}{6}[/tex]

[tex]I[/tex] = 0.002

Step-by-step explanation:

The correct option is:

d) Median is a better measure of central tendency

When a graph of a distribution of data is symmetric, it means that the left and right sides of the graph are mirror images of each other. This indicates that the data is evenly distributed around the center and that there are no extreme outliers. In such cases, the median is the best measure of central tendency, because it is the middle value of the dataset and it represents the center of the data distribution. The median is not affected by outliers.

The mean, mode, and midrange are also measures of central tendency, but they may not be as representative of the center of the data distribution when the data is symmetric. The mean is sensitive to outliers, the mode is the value that appears most frequently in the data, and the midrange is the average of the maximum and minimum values.
