Answer» Step-by-step explanation: Symptoms of COVID-19 are variable, but often include fever, cough, FATIGUE, breathing DIFFICULTIES, and loss of smell and taste. Symptoms begin one to fourteen days after exposure to the virus. Around one in five infected INDIVIDUALS do not develop any symptoms.[9] While most people have MILD symptoms, some people develop acute respiratory distress syndrome (ARDS). ARDS can be precipitated by cytokine storms,[10] multi-organ failure, septic shock, and blood clots. Longer-term damage to organs (in particular, the lungs and heart) has been observed. There is concern about a significant number of patients who have recovered from the acute phase of the disease but continue to EXPERIENCE a range of effects—known as long COVID—for months afterwards. These effects include severe fatigue, memory loss and other cognitive issues, low-grade fever, muscle weakness, and breathlessness. |

If the coefficient of variation of group A is 2.5 and coefficientof variation of group B is 2.3, then?? |
|
Answer» The coefficient of variation (CV) is a relative measure of variability that indicates the size of a standard deviation in relation to its mean. It is a standardized, unitless measure that ALLOWS you to compare variability between disparate groups and characteristics. It is also known as the relative standard deviation (RSD). In this post, you will LEARN about the coefficient of variation, how to calculate it, know when it is PARTICULARLY useful, and when to avoid it. How to Calculate the Coefficient of Variation Calculating the coefficient of variation involves a simple ratio. SIMPLY take the standard deviation and divide it by the mean. Equation for the coefficient of variation Higher values indicate that the standard deviation is relatively large compared to the mean. For example, a pizza restaurant measures its delivery time in minutes. The mean delivery time is 20 minutes and the standard deviation is 5 minutes. Coefficient of variation equation for the pizza delivery example. Interpreting the Coefficient of Variation For the pizza delivery example, the coefficient of variation is 0.25. This value tells you the relative size of the standard deviation compared to the mean. Analysts often report the coefficient of variation as a percentage. In this example, the standard deviation is 25% the size of the mean. If the value equals one or 100%, the standard deviation equals the mean. Values less than one indicate that the standard deviation is smaller than the mean (typical), while values greater than one occur when the S.D. is greater than the mean. In general, higher values represent a greater degree of relative variability. |

If the 3rd and 6th terms of an AP are 7 and 13 .find the first and the common difference. |
Answer» Answer :first term, a = 3 common difference, d = 2 Step-by-step EXPLANATION :nth term of an AP is GIVEN by, aₙ = a + (N - 1)d where a is the first term d is the common difference
a₃ = a + (3 - 1)d 7 = a + 2d -- [1]
a₆ = a + (6 - 1)d 13 = a + 5d -- [2] equation [2] - equation [1] a + 5d - (a + 2d) = 13 - 7 a + 5d - a - 2d = 6 3d = 6 d = 6/3 d = 2 Therefore, common difference = 2 Substitute d = 2 in equation [1] a + 2d = 7 a + 2(2) = 7 a + 4 = 7 a = 7 - 4 a = 3 So, first term = 3
∴ a = 3 , d = 2 |

A card is drawn at random from a pack of 52 cards. Find the probability that the cardrawn is(i) a black king(ii) either a black card or a king |
Answer» Solution 1 :-<P>The probability that it will be rain tomorrow is 0.85 . As we know that, P( E ) + P( not E ) = 1 Here, P ( E ) = 0.85 So, 1 - 0.85 = 0.15 Hence, The probability that it will be no rain tomorrow is 0.15 Solution 2 :-( 1 )Total outcomes of die = 1 , 2 , 3 , 4 , 5 , 6 = 6Favourable outcomes = 2 , 3 , 5 = 3 Probability = Favourable outcomes/Total outcomes P( getting prime numbers ) = 3/6 = 1/2 ( 2 ) Total outcomes of die = 6Favourable outcomes = 2 or 4 = 1 P( getting 2 ) = 1/6 P( getting 4) = 1/6 (3) Multiple of 2 = 4 , 6 or 3 = 6Total outcomes = 6 Favourable outcome = 2 or 1 Now, P( getting multiple of 2) = 2/6 = 1/3 P( getting multiple of 3) = 1/6 4) Total outcomes = 6Favourable outcomes = 2 , 4 , 6 P( getting even numbers) = 3/6 = 1/2 5) Total outcomes = 6Favourable outcome = 1 ( only 6 is greater than 5) P ( getting greater than 5) = 1 / 6 6) Total outcomes = 6Favourable outcome = 3,4,5 = 3 P( getting numbers between 2 and 6 ) = 3/6 = 1/2 7) Total outcomes = 6Favourable outcomes = 4 , 6 P( getting composite number) = 2/6 = 1/3 Solution 3 :-Three COINS are tossed together, Total outcomes = 8 [ HHH, HTH, HHT, THH, HHT, THT, TTH , TTT ] 1) Exactly two headsTotal outcomes = 8 Favourable outcome = 3 P ( getting exactly 2 head) = 3/8 2) At most two headsTotal outcomes = 8 Favourable outcome = 4 P( getting At most 2 heads) = 4/8 = 1/2 3) Total outcomes = 8Favourable outcome = 6 P( getting one head and one tail) = 6/8 4) Total Outcomes = 8Favourable outcome = 1 P( getting no tails) = 1/8 Solution 4 :-Total outcomes = 36 Favourable outcomes, = 9 Therefore, P( chance of throwing B) = 9/36 = 1/4 Solution 5 :-Total outcomes = 36 Favourable outcome = 3 ( (5,6), ( 6 ,5) , ( 6 ,6 ) ) P( getting greater than 10) = 3/36 = 12 Solution 6 :-1) Total outcomes = 52Total black king = 2 Favourable outcome = 2 P ( getting black king) = 2/52 = 1/26 2) Total outcomes = 52Total black cards or black king = 28 Favourable outcome = 28 P( getting EITHER black card or king) = 28/52 = 7/13 |

Prove that two tangetsareequal |
|
Answer» ANSWER Given: A circle with centre O; PA and PB are two tangents to the circle drawn from an external point P. To prove: PA = PB Construction: Join OA, OB, and OP. It is KNOWN that a tangent at any point of a circle is perpendicular to the radius through the point of contact. OA⊥PA OB⊥PB In △OPA and △OPB ∠OPA=∠OPB (Using (1)) OA=OB (Radii of the same circle) OP=OP (Common side) Therefor △OPA≅△OPB (RHS CONGRUENCY criterion) PA=PB (Corresponding parts of congruent triangles are equal) THUS, it is proved that the lengths of the two tangents drawn from an external point to a circle are equal. The length of tangents drawn from any external point are equal. So statement is correct hope it will help u |
