Maria is using a coordinate plane with the axes labeledonly with integers. She says that the point (-0.5, 2)cannot be plotted because halves are not numbered onthe x-axis. Write a note to Maria about hermisunderstanding and explain how to plot the point. I need help​

Answer»

Answer:

Integers ={Positive Natuaral Number +Natural numbers having negative sign behind it+Zero}

     ={------,-3,-2,-1,0,1,2,3,..........}

→Points marked on the X and Y axis on the Coordinate Plane=Integers only

→Point to be marked on the coordinate plane =(-0.5,2)

→As, points on both X and Y axis are integers only.To mark, -0.5 , mark a line between , 0 and -1,that will be ,-0.5.

→You can mark , any terminating decimal on the number line, which is marked with integers only.

→Terminating decimals are those decimals having  in the denominator of a fraction.

So, to plot any terminating Decimal on the coordinate plane, you have to use property of Rational Numbers ,which is, you can FIND INFINITE number of terminating Decimal between two terminating Decimal.

→Mark -0.5 between 0 and -1 on the X axis.Similarly, mark integer 2 on the Y axis.Draw a line parallel to Y axis ,passing from (-0.5,0) and line parallel to X axis passing through (0,2).The intersection of these two lines will be required point (-0.5,2).

Given :-

\bullet\sf speed_1= 50km/h\\ \\ \bullet\sf Distance_1= 100km\\ \\ \bullet\sf Speed_2= 20km/h\\ \\ \bullet\sf Distance_2=200km

To find :-

◆Identify the motion of car is UNIFORM or not

◆ AVERAGE SPEED of car !

find the average speed

\bigstar{\boxed{\sf Average \ speed = \dfrac{Total \ Distance }{Total \ Time }}}

Find the time covered by car T1

\longrightarrow\sf Speed = \dfrac{Distance }{Time }\\ \\ \longrightarrow\sf 50=\dfrac{100}{Time}\\ \\ \longrightarrow\sf 50\times Time = 100\\ \\ \longrightarrow\sf Time = \cancel{\dfrac{100}{50}}\\ \\ \longrightarrow\sf Time_1= 2 \ hours

Now Time 2

\longrightarrow\sf 20= \dfrac{200}{Time}\\ \\ \longrightarrow\sf Time = \cancel{\dfrac{200}{20}}\\ \\ \longrightarrow\sf Time_2= 10 hours

Find the average speed

\longrightarrow\sf Av.\ speed = \dfrac{D_1+D_2}{T_1+T_2}\\ \\ \longrightarrow\sf Av.\ speed = \dfrac{100+200}{2+10}\\ \\ \longrightarrow\sf Av.\ speed = \cancel{\dfrac{300}{12}}\\ \\ \longrightarrow\sf Av. \ speed =25km/h

Given : 7777=10

7777=11

7777=12

7777=13

 7777=14

 7777=15

To FIND :  Use different operators and symbols

Solution:

7 7 7 7 7 = 12

=>( 77 ÷ 7) + (7 ÷ 7) = 12

(7 + 7) - ( (7 + 7) ÷ 7)  = 12

7777 = 10

(77 - 7)÷ 7 = 10

[√7 + √7  + √7 +  √7]

= [2.64575 + 2.64575  + 2.64575 +  2.64575]

=[ 10.583 ]

= 10

[√7 + √7  + √7 +  √7]  = 10

7 +  [√7 ]   + (7÷ 7) = 10

77 ÷ (√7×√7) = 11

(√7×√7)   +  [√7+√7 ]  = 12

(77 + 7)÷ 7 = 12

7 + 7 - (7÷ 7) = 13

7 + [√7 ] + [√7 ] + [√7 ] = 13

7777=14

7 + 7 + 7 - 7 = 14

(√7×√7)  + (√7 ×√7)  = 14

7777=15​

7 + 7 + (7÷ 7) = 15

\underline{\sf To Prove :-}\\ \\\bullet\sf S_3=3(S_2-S_1)

\underline{\bigstar{\sf Solution:-}}

We KNOW the formula for the sum of NTH term of an AP

\boxed{\sf{\purple{ S_n=\dfrac{n}{2}[2a+(n-1)d]}}}

Now ,

\dashrightarrow\sf S_3=S_{3n} = \dfrac{3n}{2}[2a+(3n-1)d]\\ \\ \\ \dashrightarrow\sf S_2=S_{2n} = \dfrac{2n}{2}[2a+(2n-1)d]\\ \\ \\ \dashrightarrow\sf S_1=S_n = \dfrac{n}{2}[2a+(n-1)d]

\implies{\red{\sf S_3=\dfrac{3n}{2}[2a+(3n-1)d]-----<klux>EQ</klux>.(i)}}

★ Now First find the VALUE of -

\boxed{\rm\ S_2-S_1}

\dashrightarrow\sf \bigg[ \dfrac{2n}{2}[2a+(2n-1)d] \bigg] - \bigg[ \dfrac{n}{2}[2a+(n-1)d]\bigg]\\ \\ \\\dashrightarrow\sf \bigg[ \dfrac{2n[2a+(2n-1)d]}{2}\bigg] - \bigg[ \dfrac{n[2a+n-1)d]}{2}\bigg]\\ \\ \\\dashrightarrow\sf \bigg[ \dfrac{4na+4n^2 d-2nd}{2}\bigg] -\bigg[\dfrac{2na+n^2d-nd}{2}\bigg] \\ \\ \\ \dashrightarrow\sf \bigg[\dfrac{4na+4n^2d-2nd -2na-n^2d+nd}{2}\bigg] \ \ \ \ \big(\therefore \ By \ taking \ L.C.M \big)\\ \\ \\ \dashrightarrow\sf \bigg[\dfrac{(4na-2na)+(4n^2d-n^2d)+(-2nd+nd)}{2}\bigg]\\ \\ \\ \dashrightarrow\sf \bigg[\dfrac{2na+3n^2d-nd}{2}\bigg]\\ \\ \\ \dashrightarrow\sf \bigg[\dfrac{ n(2a+3nd-d)}{2}\bigg]\ \ \ \ \ \ \big(taking\ 'n' \ as \ common \big)\\ \\ \\ \dashrightarrow\sf \dfrac{n[2a+(3n-1)d]}{2}\\ \\ \\ \dashrightarrow\sf \dfrac{n}{2}[2a+(3n-1)d]

Now we have ,

\dashrightarrow\sf S_2-S_1= \dfrac{n}{2}[2a+(3n-1)d]\\ \\ \\ \bullet\sf Multiplying \ both \ side \ by \ (3) \\ \\ \\ \dashrightarrow\sf 3\big(S_2-S_1\big)= 3\bigg(\dfrac{n}{2}[2a+(3n-1)d]\bigg)\\ \\ \\ \dashrightarrow{\red{\sf 3\big(S_2-S_1\big)= \dfrac{3n}{2}[2a+(3n-1)d]----- eq.\ (ii)}}

★ From eq. (i) and eq.(ii) we can write -

DC = 7×2 = 14

radius = DC/2 = 7

Now,

Q. 3 A man travelled 7 km 500m in the first hour, 5 km685m in the second hour and 2 km 123m in the third hour.How far did he travel in all?​

Answer»

Answer:

Given: A man walks 7 km in 2 hrs

Later he walks 2 km in 1 hour

We need to find the AVERAGE speed and average velocity

Solution:

We know that

Speed = Total distance / Total time

Total distance travelled by man = 7 km + 2 km = 9 km

Total time TAKEN = 2 + 1 = 3 hrs

Average speed = 9/3 = 3 km/hour.

Velocity = Total displacement / Total time

Average velocity will be the same as average speed in this case since there is no direction change mentioned.

Therefore Total Displacement = Total Distance

average velocity = average speed = 3 km/hour.

Hence

Average speed = 3 km/hr.

Average velocity = 3 km/hr.

SINCE, you haven't attached any image, we shall look at every possibility in BRIEF.

Gene under consideration is a X linked recessive allele, the conditions in which it can express itself :

In a pair of homozygous recessive alleles. (Incase of woman)

In a GENOTYPE of the type : XY (Men)

Usually when females inherit a gene for sex linked recessive disorder, the latter is unable to express itself due to the PRESENCE of a pure X gene (DOMINANT). They often end up as carriers.

Case 1 : Inherited from a carrier mother.

Let us assume she married an afflicted man. (X^c will be X chromosome)

\begin{array}{|c|c|c|}\cline{1-3} & \sf X^c & \sf Y \\ \cline{1-3}\sf X^c & \sf X^cX^c & \sf X^cY \\ \cline{1-3}\sf X & \sf XX^c & \sf XY \\ \cline{1-3} \end{array}

A carrier female

Affected male and female

Normal male

In the case, 3 off springs inherit the gene but only one isn't affected.

Let us assume she married a normal man. (X chromosome)

\begin{array}{|c|c|c|}\cline{1-3} & \sf X & \sf Y \\ \cline{1-3}\sf X^c & \sf XX^c & \sf X^cY \\ \cline{1-3}\sf X & \sf XX & \sf XY \\ \cline{1-3} \end{array}

A normal male and female

A carrier female

An affected male

Again, two off springs inherit the gene but only one isn't affected.

Case 2 : Inherited from an affected mother.

Let us assume she married an affected man.

\begin{array}{|c|c|c|}\cline{1-3} & \sf X^c & \sf Y \\ \cline{1-3}\sf X^c & \sf X^cX^c & \sf X^cY \\ \cline{1-3}\sf X^c & \sf X^cX^c & \sf X^cY \\ \cline{1-3} \end{array}

All the off springs are affected.

Let us assume she married a normal man.

\begin{array}{|c|c|c|}\cline{1-3} & \sf X & \sf Y \\ \cline{1-3}\sf X^c & \sf XX^c & \sf X^cY \\ \cline{1-3}\sf X^c & \sf X^cX^c & \sf X^cY \\ \cline{1-3} \end{array}

Two affected males and one affected female.

One carrier female

In the case, 4 off springs inherit the gene but only one isn't affected.

*fill in the blanksif P(E) is probability then _____P(E)_____​

Answer»

Step-by-step explanation:

Given E is a CERTAIN event and P(E) denotes the PROBABILITY of the event E.

We KNOW that, "An event is said to be a Certain Event if there is an absolute surety on the chance of its OCCURRENCE." The probability of certain event is said to be 1.

Therefore, P(E)=1.
