Answer:

3

Step-by-step explanation:

Answer:

1a) Mean = 40

Standard Deviation = 5

b)i Which numbers on the list are within 0.5 SDs of average?

48, 50, 50

ii) within 1.5 SDs of average?

48, 50, 50, 54, 57

2a)Both of the following lists have the same average of 50. Which one has the smaller SD, and why? No computations are necessary.

The list with the smaller S.D = (ii) 50, 40, 60, 30, 70, 25, 75, 50, 50, 50

This because the results obtained from the second list (ii) is close to the mean , therefore, the Standard deviation is small.

b) Repeat, for the following two lists.

The list with the smaller S.D = (i) 50, 40, 60, 30, 70, 25, 75

This because the results obtained from the second list (i) is close to the mean , therefore, the Standard deviation is small.

Step-by-step explanation:

1a) Find the average and SD of the list 41, 48, 50, 50, 54, 57.

Average (Mean) = Sum of terms/Number of terms

= 41+ 48 + 50 + 50+ 54 + 57/6

= 300/6

= 50

Standard Deviation for the population= √(x - Mean)²/n

=√ (41 - 50)²+ (48- 50)² + (50- 50)² +(50- 50)² + (54 - 50)² +(57- 50)²/6

= √81 + 4 + 0 + 0 + 16 + 49/6

= √150/6

= √25

= 5

(b) Which numbers on the list are within 0.5 SDs of average?

Mean ± Standard deviation × 0.5

50 ± 5 × 0.5

50 - 2.5

= 47.5

50 + 2.5

= 52.5

The numbers on the list are within 0.5 SDs of average are number within 47.5 and 52.5 : 48, 50, 50

ii) Within 1.5 SDs of average?

Mean ± Standard deviation × 1.5

50 ± 5 × 1.5

50 - 7.5

= 42.5

50 + 7.5

= 57.5

The numbers on the list are within 1.5 SDs of average are numbers within 42.5 and 57.5: 48, 50, 50, 54, 57

2 (a) Both of the following lists have the same average of 50. Which one has the smaller SD, and why? No computations are necessary.

(i) 50, 40, 60, 30, 70, 25, 75

Mean is already give as 50

Standard Deviation = √(x - mean)²/n

= √(50 - 50) + (40- 50)² (60 -50)² +(30- 50)² + (70 - 50)² + (25 - 50)² (75 - 50)² /n

= √0 + 100 + 100 + 400+ 400 + 625 + 625/7

= √2250/7

= √321.4285714

= 17.92842914

(ii) 50, 40, 60, 30, 70, 25, 75, 50, 50, 50

Standard deviation = √(x - mean)²/n

√(50 -50)²+(40-50)² + (60 -50)²+ (30-50)² + (70 - 50)²+ (25-50)² +(75-50)² + (50 -50)² + (50 - 50)²+(50 - 50)²/10

= √0 + 100 + 100 + 400 + 400 + 625 + 625 + 0 + 0 + 0/10

√2250/10

√225

= √15

The list with the smaller S.D = Second list (ii) 50, 40, 60, 30, 70, 25, 75, 50, 50, 50

This because the results obtained from the second list (ii) is close to the mean , therefore, the Standard deviation is small.

(b) Repeat, for the following two lists.

(i) 50, 40, 60, 30, 70, 25, 75

Mean is already give as 50

Standard Deviation = √(x - mean)²/n

= √(50 - 50) + (40- 50)² (60 -50)² +(30- 50)² + (70 - 50)² + (25 - 50)² (75 - 50)² /n

= √0 + 100 + 100 + 400+ 400 + 625 + 625/7

= √2250/7

= √321.4285714

= 17.92842914

(ii) 50, 40, 60, 30, 70, 25, 75, 99, 1

Standard Deviation = √(x - mean)²/n

= √(50-50)² +( 40 -50)² +( 60 - 50)² + (30 - 50)²+( 70 - 50)² + (25 - 50)² + (75 - 50)² +(99 - 50)² +(1 -50)²/9

= √0 + 100 + 100 + 400 + 400+ 625 + 625 + 2401 +2401/9

= √7052/9

= √783.5555556

= 27.99206237

The list with the smaller S.D = (i) 50, 40, 60, 30, 70, 25, 75

This because the results obtained from the first list(i) is close to the mean , therefore, the Standard deviation is small.

the answer is 8/25

to get this answer i thought of all of the numbers divisible by 5 or 7 to 50 and i got 16 numbers (5,7,10,14,15,20,21,25,28,30,35,40,42,45,49,50)

i got the fraction of 16/50 then i simplified it to get 8/25 hope this helps

Answer:

x=8

Step-by-step explanation:

Set 40 + y = 90

y=50

y = 6x + 2

6x + 2 = 50

6x = 48

48/6 = x

x=8

Answer:

8

Step-by-step explanation:

(6x + 2) + 40 = 90 because the entire angle is a right angle, therefore the whole angle is 90

subtract 40 from each side: 6x + 2 = 50

now subtract 2 from each side: 6x = 48

now divide 6 from each side: x = 8

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

3 (no)

9 (no)

-7 (no)

-1 (no)

The solution to the equation 6w + 9 = 33 is 4.

The values of 2 = 3, 9, -7, and -1 are not solutions to 6w + 9 = 33.

Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.

We have,

6w + 9 = 33

6w = 24
w = 4

For w = 3

6 x 3 + 9 = 33

18 + 9 = 33

27 = 33

This is not true so it is not a solution.

For w = 9

6 x 9 + 9 = 33

54 + 9 = 33

63 = 33

This is not true so it is not a solution.

For = - 7

6 x (-7) + 9 = 33

-42 + 9 = 33

-33 = 33

This is not true so it is not a solution.

For w = -1

6 + (-1) + 9 = 33

-6 + 9 = 33

3 = 33

This is not true so it is not a solution.

Thus,

None of the values of w are solutions to 6w + 9 = 33.

Answer:

ACE

Step-by-step explanation:

Step-by-step explanation:

1.

20+25+25+36+42+56+69+74+98+100 = 545

n = 10

Mean = 545/10

= 54.5

Median = 42+56/2 = 98/2 = 49

Mode = 25 since it occurred twice

2.

If 98 is recorded as 78

20+25+25+36+42+56+69+74+78+100

= 525

Mean = 525/10 = 52.5

Median = 42+56/2 = 98/2 = 49

Mode = 25

3.

If 98 is removed

20+25+25+36+42+56+69+74+ 100= 447

n = 9

Mean = 447/9 = 49.6

Median = 42

Mode = 25
