Answer 2

The series is (d)

What is series?

A series is the cumulative sum of a given sequence of terms.

Given:

2.5 + 2.5(1.2) + 2.5(1.2)2 + ⋯ + 2.5(1.2)87

If we look at the power it is always one less the term i.e., for first term the value of k=0.

So, the series in the form of summation can be written as

[tex]^{88}\sum_{k=1}[/tex] 2.5 (1.2)^(k-1)

Seorang saudagar akan membeli 6 ekor sapi dan 5 ekor kerbau dari seorang yang memiliki 9 ekor sapi dan 7 ekor kerbau. Tentukan banyaknya cara saudagar tersebut memilih sapi dan kerbau tersebut.

Answers

Answer:

1764 ways

Step-by-step explanation:

Number of ways of selecting 6 cows from 9 cows and 5 buffaloes from 7

Using the combination formula:

nCr = n! ÷ (n - r)! r!

Ciw selection:

9C6 = 9! ÷ (9-6)! 6!

9C6 = 84

Buffalo Selection:

7C5 = 7! ÷ (7-5)! 5!

7C5 = 21

9C6 * 7C5

84 * 21

= 1764 ways

WHAT WOULD BE THE VALUE OF X?

Answers

Answer:

x = 45

Step-by-step explanation:

180-OSQ = QSR (OSR = 180 because it's a straight angle)

180 - (3x-17)= QSR

All angles in a triangle add up to 180.

SQR + QRS + RSQ = 180

25 + 2x+3 + 180-3x+17 = 180

180-x+45=180

180-180+45=x

45 = x

The mean of six numbers is 14. If one of the six numbers is removed, the mean becomes 5. What is the value of the number removed?

Answers

Answer:

Remember, the mean is calculated by adding the scores together and then dividing by the number of scores you added. In this case, the mean would be 2 + 4 (add the two middle numbers), which equals 6. Then, you take 6 and divide it by 2 (the total number of scores you added together), which equals 3.

Step-by-step explanation:

Hope I helped.It's just a reminder of helpful things for means!

Answer:

59

Step-by-step explanation:

Suppose a, b, c, d, e and f represent the 6 numbers.  

Then, [tex]\frac{a + b + c + d + e + f}{6} = 14\\[/tex]

(1)         a + b + c + d + e + f = 84

Let's remove f

then [tex]\frac{a + b + c + d + e}{5} = 5[/tex]

(2)        a + b + c + d +e = 25

Substitute 25 in for  a + b + c + d +e in equation (1)

We have 25 + f = 84

                       f  = 59
