61.

40 ==> 100 %
x ==> 15 %

15*40/100 = 6.

Therefore, merely 6 students received C grades.

62.

23 500 ==> 100%
x ==> 42 %

42*23500/100 = 9870

Therefore 9870 people in the town are over 45 years of age.

You continue wth this method and you'll find for the 63, 64, 65.

In maths, you have to understand what you're doing dude ^^.

Whatever the answer for 64 and 65 are

64.

21.50*20/100 = 4.3

65.

250 ==> 100 %
45 ==> x %

x = 45*100/250 = 18 %

i will let you do the 63 alone, give me what you have found in the comments, i'll verify your answer.

Hope this helps !

If a_1=2a 1 =2 and a_n=(a_{n-1})^2+5a n=(a n−1 ) 2 +5 then find the value of a_4a 4

pentagon [3]

Using the given information, the value of $a_{4}$ is 7401

<h3>Sequence</h3>

From the question, we are to determine the value of $a_{4}$

From the given information,

$a_{n} = (a_{n-1})^{2} +5$

Then we can write that

$a_{4} = (a_{3})^{2}+5$

$a_{3} = (a_{2})^{2}+5$

$a_{2} = (a_{1})^{2}+5$

Also, from the given information

$a_{1} = 2$

Then,

$a_{2} = (a_{1})^{2}+5$ becomes

$a_{2} = (2)^{2}+5$

$a_{2} = 4+5$

$a_{2} = 9$

Also,

$a_{3} = (a_{2})^{2}+5$ becomes

$a_{3} = (9)^{2}+5$

$a_{3} = 81+5$

$a_{3} = 86$

Then,

$a_{4} = (a_{3})^{2}+5$ becomes

$a_{4} = (86)^{2}+5$

$a_{4} = 7396 +5$

$a_{4} = 7401$

Hence, the value of $a_{4}$ is 7401

Workout the probability that spinner A lands on 2 and spinner b does not land on b

zzz [600]

Spinner diagram isn't attached. A related spinner diagram has been attached below to provide an hypothetical solution to the problem

Answer:

4 / 15

Step-by-step explanation:

For the numbered spinner :

P(landing on 2) = required outcome / Total possible outcomes

Total possible outcomes = (1, 2, 3) = 3

Required outcome = (1) = 1

P(landing on 2) = 1 /3

Lettered spinner :

P(does not land on b)

Total possible outcomes = (A, B, C, D, E)

Required outcome = (a, c, d, e)

P(does not land on b) = 4 / 5

Hence,

P(lands on 2, does not land on b) in this scenario is :

1/3 * 4/5 = 4 / 15
