|
Answer» ong>Question :- Find the RECIPROCAL of 11/5 . ANSWER :- As we know that, The reciprocal of a number is EQUAL to 1 DIVIDED by the number. So, → reciprocal of 11/5 = 1 ÷ (11/5) → reciprocal of 11/5 = 1 * (5/11) → reciprocal of 11/5 = (5/11) (Ans.) Or, we can say that, when we MULTIPLY a number by its reciprocal we get 1.. So, → (11/5) * reciprocal = 1 → reciprocal = 1/(11/5) → reciprocal = 1 * (5/11) → reciprocal = (5/11) (Ans.) |

If the mean of the numbers 15, 20, a, 32, bis 25, find b in terms of a |
|
Answer» ONG>Answer: Step-by-step explanation: ARITHMETIC MEAN OR MEAN OR AVERAGE :
The arithmetic mean of a set of observations is OBTAINED by DIVIDING the SUM of the values of all observations by the total NUMBER of observations .
Mean = Sum of all the observations / Total number of observations .
MEAN = Σfixi / Σfi
[‘Σ’ Sigma means ‘summation’ ]
FREQUENCY DISTRIBUTION TABLE IS IN THE ATTACHMENT From the table : Σfixi = 445 + 10p , Σfi = 27 + p
MEAN = Σfixi / Σfi Given : Mean = 15
15 = (445 + 10p) / (27 + p)
15 × (27 + p) = 445 + 10p
405 + 15p = 445 + 10p
15p - 10p = 445 - 405
5p = 40
p = 40/5 = 8
p = 8
Hence, the value of ‘p’ is 8. HOPE THIS ANSWER WILL HELP YOU…. |

Plot the following points and write the name of figure thus obtained. Find its perimeter. A (2, 0), B (4, 0), C (2,-2), D (4,-2) |
|
Answer» ong>Figure we obtained is Rhombus and Area is 16 unit². Step-by-step explanation: Coordinates of the points, A( -4 , 4 ) , B( - 6 , 0 ) , C( -4 , -4 ) and D( -2 , 0 ) We need to plot the points in the coordinate plane and name the figure. Find the Area of the Figure. Graph is attached after plotting. ABCD is a Rhombus as opposite SIDES are parallel and all sides are EQUAL and Diagonals are PERPENDICULAR bisector of each other. Area of the Rhombus ABCD = Area of the ΔABD + Area of the ΔACD From the figure, In ΔABD Base = 4 unit HEIGHT = 4 unit In ΔACD Base = 4 unit Height = 4 unit Area of the Rhombus ABCD = 1/2 × Base × Height + 1/2 × Base × Height = 1/2 × 4 × 4 + 1/2 × 4 × 4 = 8 + 8 = 16 unit² Therefore, Figure we obtained is Rhombus and Area is 16 unit².

What is x + yplease help me |
|
Answer» ong>Answer: The formula is (x-y)³=x³-3x²y+3xy²-y³. You convert it to (x-y)³=x³-3xy(x-y)-y³ for an ILLUSTRATION. ... You take the DRAWING of the formula (x+y)³=x³+3x²y+3xy²+y³ from above and replace a by the difference x-y. Then the edges are (x-y)+y with different COMBINATIONS (on the left). Step-by-step explanation: (x,y) has the meaning of plane's point COORDINATES. The first x is the horizontal coodinate (abscisa) and second is the vertical coordinate (ordenate). Both are coordinates. (x,y) has the meaning of a COMPLEX number: x is the real part and y is the imaginary part: x+yi. |
