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%.

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. Please mark me as the Brainliest.

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 |

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-
For (i)
and so, and Since Therefore (a+b)/3 = 2 so, a+b =6.................EQ. (1) ALSO, 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! |

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 |

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 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.
