The value of coins in the pockets of several students is recorded. What is the mean of the values: 10, 20, 35, 35, 35, 40, 45, 45, 50, 60. A. 10 cents B. 35 cents C. 37.5 cents D. 50 cents

Answers

Answer:

C. 37.5

Step-by-step explanation:

10 10 + 20 + 35 + 35 + 35 + 40 + 45 + 45 + 60 + 50=375

375÷10=37.5

The mean of the given data set 10, 20, 35, 35, 35, 40, 45, 45, 50, 60 is 37.5 so option (C) will be correct.

What is mean?

The mean is the average of a data set. Mean gives us the idea of that how much amount of overall data have.

In other words, the mean is the foundation of the deviation of data from all data sets.

Mean = sum of data / Number of data

For example, if you have marks in 5 subjects like 40,45,44,46,48 then the mean will be

( 40 + 45+ 44 + 46 + 48) /5 = 44.6.

Given the data set,

10, 20, 35, 35, 35, 40, 45, 45, 50, 60

Now mean is given as

Mean = sum of data / Number of data

So,

Mean = (10+20+35+35+35+40+45+45+50+60)/10

Mean = 37.5

Hence "The mean of the given data set 10, 20, 35, 35, 35, 40, 45, 45, 50, 60 is 37.5".

If 1/6x + 3 = 7 what is x

Answers

Answer:

x = 24

Step-by-step explanation:

1/6 x + 3 = 7

1/6 x = 4

x = 24

Step-by-step explanation:

The expression is 1/6x+3=7

1/6x+3=7

First, you subtract 3 from both sides

1/6x=4

Then you divide 1/6 from both sides

Dividing fractions is confusing, so I will show you how to do it

4/1 / 1/6

Because you can't divide 1 by 6, you KCF, or keep change flip.

You keep the 4/1, you change the operation to multiplication, and flip 1/6 to make it 6/1.

Now the problem is 4x6=24

Tyler wants to use $300 he has saved to buy a new guitar and join a music club. The guitar costs $140. The music club has a $25 membership fee, and for $11.95 per month, members can download 30 songs. Tyler can afford the music club membership for____ months, after which he will have_____ left.​

Answers

Answer:

11 months ; $3.55

Step-by-step explanation:

Amount saved = $300

Cost of guitar = $140

Membership fee = $25

Monthly fee = $11.95

For how manyonths can Tyler afford the membership :

The one time fee = (membership fee + cost of guitar)

= $140 + $25 = $165

Amount left = $300 - $165

Amount left = $135

Number of monthly fee the balance can afford :

Amount left / monthly fee

= $135 / $11.95

= 11.29

Hence, the number of months he can pay for is 11 months

Amount left = $135 - ($11.95 * 11 months)

$135 - $131.45

= $3.55

A finance charge is regarded as the cost incurred when a person borrows money and it often includes interest and other fees.

To find the finance charges,  the formula is:

Answer:

(x +5) (x +4) = 0

Step-by-step explanation:

x^2 + 9x +20 = 0

x^2 + 4x + 5x +20 = 0

x(x + 4) + 5(x + 4) = 0

(x +5) (x +4) = 0

Answer:

Step-by-step explanation:

x^2 + 9x = -20​

x^2 + 9x + 20 = 0

factor the expression

(x + a)(x + b)

a + b = 9

a = 4

b = 5

ab = 20

x + 4 = 0   and x + 5 = 0

b. What is the approximate percentage of women with platelet counts between 128.8 and 378.0?

b. Approximately

% of women in this group have platelet counts between 128.8 and 378.0.

(Type an integer or a decimal. Do not round.)

Answers

Answer:

a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or

between 191.1 and 315.7?

68%

b. What is the approximate percentage of women with platelet counts between 128.8 and 378.0?

95%

Step-by-step explanation:

The Empirical rule formula states that:

1) 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

2) 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

a. What is the approximate percentage of women with platelet counts within 1 standard deviation of the mean, or

between 191.1 and 315.7?

μ = mean = 253.4

σ = standard deviation = 62.3.

μ - σ

= 253.4 - 62.3

= 191.1

μ + σ

= 253.4 + 62.3

= 315.7

Therefore, the first empirical rule holds for Question a. This states that 68% of data falls within 1 standard deviation from the mean - that means between μ - σ and μ + σ .

Therefore, the approximate percentage of women with platelet counts between 191.1 and 315.7 is 68%

b. What is the approximate percentage of women with platelet counts between 128.8 and 378.0?

μ = mean = 253.4

σ = standard deviation = 62.3.

Applying the second rule of the empirical rule: this states that: 95% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ .

For x = 128.8

μ - 2σ

= 253.4 - 2 × 62.3

= 128.8

μ + 2σ

= 253.4 + 2 × 62.3

= 378

Therefore, the approximate percentage of women with platelet counts between 128.8 and 378.0 is 95%

6(5 - 2v) = 4(-3v - 1)​

Answers

Answer:

30=-4

Step-by-step explanation:

Simplifying

6(5 + -2v) = -4(3v + 1)

(5 * 6 + -2v * 6) = -4(3v + 1)

(30 + -12v) = -4(3v + 1)

Reorder the terms:

30 + -12v = -4(1 + 3v)

30 + -12v = (1 * -4 + 3v * -4)

30 + -12v = (-4 + -12v)

Add '12v' to each side of the equation.

30 + -12v + 12v = -4 + -12v + 12v

Combine like terms: -12v + 12v = 0

30 + 0 = -4 + -12v + 12v

30 = -4 + -12v + 12v

Combine like terms: -12v + 12v = 0

30 = -4 + 0

30 = -4
