Step-by-step explanation:

Rules of rounding off:

1.) If the digit following the last digit to be kept is less than five, the last digit is left unchanged.

2.) If the digit following the last digit to be kept is five or more, the last digit to be kept is increased by one.

A. 37.63 times 0.54

37.63 × 0.54 = 20.3202

20.3202 ≈ 20.3

B. 54.49 times 0.45

54.49 × 0.45 = 24.5205

24.5205 ≈ 24.5

C. 1.19 times 1.45

1.19 × 1.45 = 1.7255

1.7255 ≈ 1.7

D. 0.81 times 8.01

0.81 × 8.01 = 6.4881

6.4881 ≈ 6.5

E. 27.83 times 13.64

27.83 × 13.64 = 379.6012

379.6012 ≈ 379.6

What is the median please help please help

Paladinen [302]

Answer:

54.5

Step-by-step explanation:

To find the median, first we have to put the numbers in ascending/increasing order.

43, 60, 50, 36, 58, 50, 73, 59, 69, 51 is your set

36, 43, 50, 50, 51, 58, 59, 60, 69, 73 is your set in order.

The median is the middle number of the data set. Your set has an even number of entries, so we have to average the 2 middle numbers, which are 51 and 58.

36, 43, 50, 50, 51, 58, 59, 60, 69, 73

51 + 58 = 109

109/2 = 54.5

Calculate to the nearest million m³.the current amount of water in the berg river dam

swat32

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the dimension of the dam is not given.

However, a general way of calculating volume is to calculate the base area and the multiply by height.

Take for instance,the dam has a rectangular base of 20m by 30m.

The base area will be

Area = 20m * 30m = 600m²

If the height of the water in the dam is 40m, then the volume is:

Volume = 600m² * 40m

Volume = 24000m³

Here are the first five terms of an arithmetic sequence.

Assoli18 [71]

Answer:

The nth term of an AP will be 27 -7n.

Step-by-step explanation:

First five terms of the Arthemetic Sequence is given to us , which is 26 , 19 , 12 , 5

Hence here Common Difference can be found by subtracting two consecutive terms . Here which is 19 - 26 = (-7) .

Here first term is 26 .

And the nth term of an AP is given by ,

★ T_n = a + ( n - 1) d

Substituting respective values ,

⇒ T_n = a + ( n - 1 )d

⇒ T_n = 26 + (n - 1)(-7)

⇒ T_n = 26 -7n+1

⇒ T_n = 27 - 7n

<h3>Hence the nth term of an AP can be found using T_n = 27 - 7n. </h3>

A bag contains 20 marbles of the same size that are blue, green, and red. The probability of picking a blue marble is 20%. The p

vredina [299]

Answer:

30% of picking a red marble, it is likely to occur.

Step-by-step explanation:

50% of green and 20% of blue. The most logical is to add to 100%. 50+20=70, 100-70=30. Thats the 30% of red. Since red is 10% than blue, it is likely to get a red marble.
