The weekly demand of a cell phone shop is following the normal distribution with average number of cell phones sold is 200 units and it has also been found that 90% of time the demand is lying less than 220 units.a. Using this information find the standard deviation of the distribution.b. Determine the lowest stock that the company should maintain so that the probability of shortage is not higher than 5%.

Answer»

Given :  The weekly demand of a cell phone shop is following the normal distribution with average number of cell phones SOLD is 200 units and it has also been found that 90% of time the demand is lying less than 220 units.

To find : standard deviation of the distribution.

lowest stock that the company should maintain so that the probability of shortage is not higher than 5%.

Solution:

Mean = 200

90% of time the demand is lying less than 220 units.

for 90 % z score = 1.282

Z score = ( value - Mean)/SD

=> 1.282 = ( 220 - 200)/SD

=> 1.282 = 20/SD

=> SD  = 15.6

standard deviation of the distribution. = 15.6

Lowest stock that the company should maintain so that the probability of shortage is not higher than 5%.

=> 95 %  of time demand should meet

Z score for 95 % = 1.645

1.645 = ( value - 200)/(15.6)

=> Value = 225.66

=> Value = 226

226 is the  lowest stock that the company should maintain so that the probability of shortage is not higher than 5%.

PLZ HELP!!! GEOMETRY ASAP

Answer»

Answer:

First join AO and BQ.

( I am SORRY I am not able to put a picture but you will surely understand continue reading )

We know that, tangents are perpendicular to the radii of the circle.

Hence AO and BQ are perpendicular to AC.

Now in triangles AOC and BQC,

angle OAC = angle BQC = 90 DEGREES.

and

angle ACO = angle BCQ

By AA similarity, triangles ACO and BCQ are similar.

So according to the properties of similar triangles,

AO / QB = CO / CQ.

Hence proved.

Mary's scarf is 64 centimeters long. How many millimeters is the length of the scarf? 640 millimeters 6.4 millimeters 128 millimeters 6,400 millimeters

Answer»

ANSWER:

640 millimetres

we KNOW that,

1 centimetre = 10 millimetres.

therefore,

64 centimetres = 64 × 10 millimetres

= 640 millimetres

hence answer is 640 millimetres.

In a triangle ABC, if 2∠A = 3∠B = 6∠C, then the measure of ∠B is (a) 30 degree (b) 75 degree c) 90 degree (d) 60 degree

Answer»

According to the properties of a triangle, the sum of its INTERIOR ANGLES is 180 degrees.

So, A+B+C=180

Again, 2A=3B=6C (given)

=> A=3C and B=2C

On substituting in 1st equation we GET -

3C+2C+C=180 => 6C=180 => C=30 degree

Thus, B=2C=2×30=60 degrees

Thus, OPTION d is CORRECT

Find x. It's an indices question.

Answer»

Hey Buddy

Here's the answer

-----------------------------------------------

Firstly we'll INVERSE the fraction and if we inverse the fraction the sign of power changes

For example

1 / x^2 = x^(-2)

Now Solving

We can write 343 as 7^3

Now,

==> 1 / 7^(x - 8) = 7^3

==> 7^[-( x - 8 )] = 7^ 3

Now by comparing both sides

==> - ( x - 8 ) = 3

==> 8 - x = 3

==> x = 8 - 3

==> x = 5

HOPE OT HELPS

15. Find the values a and b for which the following pair of linear equations have an infinitely number of solutions:(i) ( a + b ) x – 2 b y = 5 a + 2b + 1, 3x – y = 14 (ii) ( 2 a -1 ) x + 3 y = 5 , 3 x + ( b – 1 ) y = 2​

Answer»

Answer:

(i) a = 5

b=1

Step-by-step explanation:

Infinite no. of solutions are possible if and only if-

\frac{a_{1} }{a_{2} } = \frac{b_{1} }{b_{2} } =\frac{c_{1} }{c_{2}}

For (i)

a_{1}= (a+b)         b_{1} = -2\\     b_{2} = -1

a_{2} = 3

and c_{1}= -5a-2b-1\\c_{2} = -14

so, \frac{a_{1}}{a_{2}} = (a+b)/3

and \frac{b_{1}}{b_{2}} = -2/-1= 2

Since \frac{a_{1}}{a_{2}} = \frac{b_{1}}{b_{2}}

Therefore

(a+b)/3 = 2

so, a+b =6.................EQ. (1)

ALSO, \frac{b_{1}}{b_{2}} =\frac{c_{1}}{c_{2}}

So, 2= (5a + 2b + 1)/14

or 5a + 2b = 27................eq (2)

Solving (1) and (2) , we get

a = 5

b=1

Similarly you can SOLVE for (ii)

Hope this is useful. Please rate the answer!

Find the smallest positive integer greater than one which yields a remainder of one when divided by any single positive integer greater than 1. ​

Answer»

Step-by-step explanation:

Since this NUMBER is 1 greater than the number that can be divided by 4, 5, and 6, we have to find the LCM of it. FIRST, let’s find the prime factorizations:

4: 2*2

5: 5

6: 2*3

2*2*3*5 = 60 (Only two 2’s because there is a max of two, LIKE 2*2 is two, and 2 is one, so we take the largest amount, two).

60 + 1 = 61 ANS

.In the given figure, find PM (a) 3 cm (b) 5 cm (c) 4 cm (d) 2 cm

Answer»

Answer:

In the given figure ∠LOP = ∠MOP , OL = 3cm , OP = 5cm , ∠PLO = ∠PMO  [ as right angles ]

Firstly we have to prove that traingle LOP is congruent to traingle mop

se we will PROOF the congruence of those traingle

s

In traingle LOP and traingle MOP

  ∠LOP = ∠MOP

 OP = OP [common]

∠PLO = ∠PMO [ right angles ]

Hence , ΔLOP ≅ΔMOP

PM = PL [ by CPCT ]

So , here we have got to know that PL = PM so if we find tHe value of PL it will be equal to PM

So , we can find the value of PL by the pythagoras theorem that is to be APPLIED in ΔPLO ,

OP²= LP²+OL²

[5]²= [3]²+LP²

25= 9 +LP²

LP²= 25- 9

LP= √16 = 4cm

As we know that PM= PL

So , PL = PM = 4cm

What is the length of the longest tape which can be used to measure exactly 1m75cm,4m50cm,6m50cm​

Answer»

Answer:

HCF by prime factorization method :

HCF of two or more numbers = PRODUCT of the smallest power of each common prime factor involved in the numbers

SOLUTION :

First change the length into cm.

[1m= 100cm]

1m 75 cm = 1×100 +75 = 100 +75= 175 cm

4M 50CM= 4×100+50= 450 cm

6m 50 cm= 6×100+50 = 650 cm

Find the H.C.F of 3 lengths 175 cm, 450 cm, 650 cm

HCF by prime factorization method :

175 = 5×5×7 = 5²×7

450 = 2× 5×5×11= 2 × 5² ×11

650 = 2× 5×5 ×13 = 2× 5² × 13

H.C.F= 5² = 5×5 = 25

The longest tape which can be used to MEASURE exactly the length 175 cm, 450 cm, 650 cm is 25 cm

Hence, the length of the longest tape which can be used to measure exactly 1m 75cm, 4m 50cm and 6m 50cm is 25 cm.
