Answer:

Ai. Common ratio = 2/3

Aii. First term = 54

B. Sum of the first five terms = 422/3

Step-by-step explanation:

From the question given above, the following data were obtained:

3rd term (T3) = 24

6Th term (T6) = 64/9

First term (a) =?

Common ratio (r) =?

Sum of the first five terms​ (S5) =?

Ai. Determination of the common ratio (r).

T3 = ar²

T3 = 24

24 = ar²....... (1)

T6 = ar⁵

T6 = 64/9

64/9 = ar⁵......... (2)

The equation are:

24 = ar²....... (1)

64/9 = ar⁵......... (2)

Divide equation 2 by equation 1.

64/9 ÷ 24 = ar⁵ / ar²

64/9 × 1/24 = r³

8/27 = r³

Take the cube root of both side

r = 3√(8/27)

r = 2/3

Thus, the common ratio is 2/3

Aii. Determination of the first term (a).

T3 = ar²

3rd term (T3) = 24

Common ratio (r) = 2/3

First term (a) =?

24 = a(2/3)²

24 = 4a/9

Cross multiply

24 × 9 = 4a

216 = 4a

Divide both side by 4

a = 216/4

a = 54

Thus, the first term (a) is 54

B. Determination of the sum of the first five terms.

Common ratio (r) = 2/3

First term (a) = 54

Number of term (n) = 5

Sum of first five terms (S5) =?

Sn = a[1 –rⁿ] / 1 – r

S5 = 54[1 – (⅔)⁵] / 1 – ⅔

S5 = 54 [1 – 32/243] / ⅓

S5 = 54 (211/243) × 3

S5 = 54 × 211/81

S5 = 6 × 211/9

S5 = 2 × 211/3

S5 = 422/3

Thus, the sum of the first five terms is 422/3

Answer:

a

The null hypothesis is  [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]

The alternative hypothesis is [tex]H_a : \sigma_1 ^2 > \sigma^2_2[/tex]

b

[tex]F_{critical} = 1.8608[/tex]

c

[tex]F = 2.9085[/tex]

d

    The decision rule is  

Reject the null hypothesis

e

There is sufficient evidence to support the researchers claim

Step-by-step explanation:

From the question we are told that

 The first sample size is  [tex]n_1 = 30[/tex]

 The sample variance for elementary school is  [tex]s^2_1 = 8324[/tex]

 The second sample size is  [tex]n_2 = 30[/tex]

  The sample variance for the secondary school is  [tex]s^2_2 = 2862[/tex]

   The significance level is  [tex]\alpha = 0.05[/tex]

The null hypothesis is  [tex]H_o : \sigma^2_1 = \sigma^2 _2[/tex]

The alternative hypothesis is [tex]H_a : \sigma_1 ^2 > \sigma^2_2[/tex]

Generally from the F statistics table  the critical value of [tex]\alpha = 0.05[/tex] at first and  second degree of freedom [tex]df_1 = n_1 - 1 = 30 - 1 = 29[/tex] and  [tex]df_2 = n_2 - 1 = 30 - 1 = 29[/tex] is  

         [tex]F_{critical} = 1.8608[/tex]

Generally the test statistics is mathematically represented as

       [tex]F = \frac{s_1^2 }{s_2^2}[/tex]

=>   [tex]F = \frac{8324 }{2862}[/tex]

=>   [tex]F = 2.9085[/tex]

Generally from the value obtained we see that  [tex]F > F_{critical }[/tex] Hence

   The decision rule is  

Reject the null hypothesis

    The conclusion is  

  There is sufficient evidence to support the researchers claim

Answer:

The first four terms of the sequence are: {-10,-23,-62,-179}

Step-by-step explanation:

Given recursive formula is:

[tex]a_n = 3a_{n-1}+7[/tex]

First term = a1 = -10

The first term is already known. In order to find the next terms, we will put n=2,3,4 in the recursive formula.

Putting n=2

[tex]a_2 = 3a_{2-1}+7\\a_2 = 3a_1+7\\a_2 = 3(-10)+7\\a_2 = -30+7\\a_2 = -23[/tex]

Putting n=3

[tex]a_3 = 3a_{3-1}+7\\a_3 = 3a_2+7\\a_3 = 3(-23)+7\\a_3 = -69+7\\a_3 = -62[/tex]

Putting n=4

[tex]a_4 = 3a_{4-1}+7\\a_4 = 3a_3+7\\a_4 = 3(-62)+7\\a_4 = -186+7\\a_4 = -179[/tex]

Hence,

The first four terms of the sequence are: {-10,-23,-62,-179}

Step-by-step explanation:

Answer:

The answer is A. g(x) = f(x) + 4

A number raised to a power is the same as multiplying the number by itself the number of times of the power.

11^2 = 11 x 11 = 121

The answer is 121

Answer:

f(n) = f(n-1)*.6 + 20

Step-by-step explanation:

f(0) = 50

f(n) = f(n-1)*.6 + 20

In fact, since f(0) = 50, f(n) = 50.

Answer:

C. Supplementary angles

Step-by-step explanation:

Supplementary angles always equal 180 degrees.

The answer is (C) because, the sum of both the angle is equals to 180° i.e they are pair of supplementary angles.

20

There are two ways to solve this (both will end up with the same answer):

1st way:

You can find 4/9 of 36 to find how many displays the class explored so far. You can write it as 4/9 x 36, which is equal to 16. So, the class explored 16 displays so far. All you need to do is subtract 16 from 36 to find how many displays the class needs to explore, which can be written as 36-16, and is equal to 20.

Final answer: 20

2nd way:

You can do 1 minus 4/9 to find the left over fraction of the displays that the class needs to explore, which is equal to 5/9. Then, you need to find 5/9 of 36 to find how many displays are left for the class to explore. You can write it as 5/9 x 36, which is equal to 20.

Final answer: 20

Hope you understand and that this helps with your question :)

The probability that a randomly selected camper likes to have a cookout or swimming, but not both, is 0.10.

The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.

The Venn diagram displays the campers’ preferences.

One circle is labeled S, 0.06,

the other circle is labeled C, 0.04,

the shared area is labeled 0.89,

and the outside area is labeled 0.01.

The probability that a randomly selected camper likes to have a cookout or swimming, but not both,

= 0.06 + 0.04

= 0.10

Therefore, 0.10 is the required probability.
