Median: 85.5

Step-by-step explanation:

Knowledge Needed

Median is the middlemost value of the data set.

For example, we have a data set:

1, 7, 5

Line up in least to greatest.

1, 5, 7

Median is 5.

If there is an even amount of terms, the value of the median is the average of the 2 middlemost terms. For example:

1, 7, 16, 8

Line up in least to greatest.

1, 7, 8 , 16

(7 + 8)/2, average: 7.5

Median is 7.5

79 79 79 79 79 83 83 83 83 88 88 88 88 88 93 93 93 93

Middle of the set: 83 & 88 (Because there is an even amount of terms).

83 + 88 = 171

171/ 2= 85.5

By SAS congruence, the triangles LMO and LNO are concurrent.

Here given,

LM ≅ ON

∠ M ≅ ∠ N

From the figure it is clear that, the side LO is shared by both triangles.

So, in the concurrency SAS, two sides of a triangle are equal, and an angle is equal.

As a result, the triangles LMO and LNO are congruent by SAS congruence if LM ≅ ON, ∠ M ≅ ∠ N .

Step-by-step explanation:

it is given that for first 30 km, the speed of bicyclist is v km/hour

time taken to cover first 30 km is given by

          ( )

for next 17 km the speed of bicyclist is 2 km/hour greater than his original speed

so the speed to cover next 17 km = v+2

time taken to cover next 17 km is given by

Simplify is making something simple. In mathematics, simplification means reducing the expression/ fraction/problem in a simpler form by using different operations.  

In the process of simplification, some basic rules are needed to be used. The principle of BODMAS (B= Bracket, O = Of, D = Division, M = Multiplication, A = Addition, S = Subtraction)must be followed for solving the questions.

The equation is :

[tex]\frac{a^{2} - 16 }{ a^{2} - 25 }[/tex]   ÷   [tex]\frac{a^{2} - 2a - 8}{a^{2} + 10a + 25}[/tex]

=[tex]\frac{a^{2} - 4^{2} }{a^{2} - 5^{2} }[/tex]  ÷   [tex]\frac{a^{2} - 2a - 8}{a^{2} + 10a + 25}[/tex]

= [tex]\frac{ (a +4 ) ( a - 4 )}{ (a + 5) ( a - 5 )}[/tex]    ÷   [tex]\frac{a^{2} - 4a + 2a - 8}{a^{2} + 5a + 5a + 25}[/tex] ( by applying middle term factor method)

(using [tex]a^{2} - b^{2}[/tex] formula )

=  [tex]\frac{ (a+4) ( a-4 )}{(a +5 ) (a - 5)}[/tex]     ÷      [tex]\frac{a(a -4) + 2 (a - 4)}{a (a + 5) + a (a + 5)}[/tex] ( by applying middle term factor method)

The rate of interest for simple compounding if Louis is offered an interest rate of 6.35% for an investment with continuous compounding, is 0.0656 or 6.56%, so option D is correct.

When the loan is given to you, then some amount is charged to you for the principal amount and that is called interest.

Given:

Louis is offered an interest rate of 6.35% for an investment with continuous compounding,

Here, P will be the same, the amount will be the same and the time period will be the same then,

The amount in simple compounding = The amount in continuous compounding

[tex]P(1 + r)^t = Pe^{Rt}[/tex]

Here, r is the rate of interest for simple compounding,

[tex]1 + r = e^{0.0635}[/tex]

r = 1.0656 - 1

r = 0.06556

r = 0.0656

The graph of the parabola declines through (-5, 2), (-3, 0), (-2, 0), (0, 1), (1, 2), (2, 3), (3, 5) on the x y coordinate plane represents the function.

A function is defined as the relation between the x and y coordinates such that no value of x maps to two values of y.

A vertical line test is a test used to determine whether the graph given is a function or not. This is a test where we draw a vertical line passing through a point x. If the graph is a function, then the vertical line will not intersects the graph at two points.

That is, no x coordinate maps to more than 1 y coordinate.

In the first graph of ellipse, the value -5 maps to two values 3 and 5. So this is not a function.

In the parabola all x values only maps to one y value. So this graph represents a function.

In the third graph, the value 3 maps to three values of y, 3, 2, and 1. So this is also not a function.

In the fourth graph, -2 maps to both 4 and 2, which also indicates that the given graph is not a function.

Hence the second graph of the parabola represents a function.

a) A recurrence relation for the number of bit strings of length n that contain three consecutive 0s :

a_n = a_(n-1) + a_(n-2) + a_(n-3) + 2^(n-3)   for n ≥ 3

b) The initial conditions are:

a_0 = a_1 = a_2 = 0 and a_3 = 1

c) There are 47 bit strings of length seven contain three consecutive 0s

Let s_n be a string of length n that does not have 3 consecutive 0's, and a_n be the number of strings  that contain three consecutive 0's

Consider a string of length n -1 that does not have 3 consecutive 0's, s_(n-1)

If we add 1 to this string, then we get a string s_n.

Consider a string s_(n-2)

If we add 10 at the end, then we get a string s_n

Now consider a string s_(n-3)

If we add 100 at the end we get a string s_n.

Now we got all possible strings s_n: that end in 1 (i.e. the last 3 digits could be 001, 011, 101 and 111),

Those strings that end in 10 (i.e. the last 3 digits could be 010 and 110)

and those strings  that end in 100. There are no other possibilities without having 3 consecutive zeros.

In the third case, there are a_(n-3) possibilities. And, in the fourth case, there are 2^(n-3) possibilities.

Hence the recurrence relation is

So, a_n = a_(n-1) + a_(n-2) + a_(n-3) + 2^(n-3)   for n ≥ 3

The initial conditions are a_0 = a_1 = a_2 = 0 and a_3 = 1

The recurrence gives the sequence of positive integers 0, 0, 0, 1, 3, 8, 20, 47, 107, 238, 520, 1121, 2391, . . . .

Hence there are a_7 = 47 bit strings of length seven that contain

three consecutive 0's.

Therefore, a) the recurrence relation:

a_n = a_(n-1) + a_(n-2) + a_(n-3) + 2^(n-3)   for n ≥ 3

b) Initial conditions: a_0 = a_1 = a_2 = 0 and a_3 = 1

Answer:

  Zach is correct

Step-by-step explanation:

You want to know if reflection across the two axes and translation right will achieve the same effect if the transformations are done in any order.

Translation right adds a value to the x-coordinate.

Reflection over the y-axis changes the sign of the x-coordinate.

If the order of these two transformations is changed, the result will change.

Example

Consider point (0,0) and the translation right 1 unit.

  Reflection, then translation: (0, 0) ⇒ (0, 0) ⇒ (1, 0)

  Translation, then reflection: (0, 0) ⇒ (1, 0) ⇒ (-1, 0)

Type I errors (also known as a "false positive") occur when a test erroneously rejects a true null hypothesis. In other words, the test incorrectly concludes that the observed effect is significant or real when, in fact, it is not.

A type I error is a statistical mistake where the null hypothesis is rejected, despite it being true. This is also known as a false positive. This means that the test concluded that the observed effect was significant when in reality, it was not. Type I errors are more likely to occur when the sample size is small or when too many tests are conducted at once. To avoid type I errors, it is important to use an appropriate sample size and to consider the power of the test before conducting it.
