=> x = 50° (Ans)

Solve the equation below for m.

3

Answers

Answer: 30

Step-by-step explanation:

3(0.3m + 6) + m =75

(0.3 x 3 = 0.9)

(6 x 3 = 18)

0.9m + 18 + m = 75

0.9m + m + 18 = 75

(m=1)

1.9m + 18 = 75

1.9m = 75 - 18

1.9m = 57

m = 57÷ 1.9

m = 30

7. After a discount of 30%, you pay $49.00 for a video game. What was the original price of the game?

Answers

Answer:

$70.00

Step-by-step explanation:

Percentage of original price paid

= 100% -30%

= 70%

70% of original price ----- $49.00

1% of original price ----- $49.00 ÷70= $0.70

100% of original price ----- $0.70 ×100= $70.00

your answer to the nearest thousandth.

Answers

Answer:

0.013

Step-by-step explanation:

Use binomial probability:

P = nCr pʳ (1−p)ⁿ⁻ʳ

where n is the number of trials,

r is the number of successes,

and p is the probability of success.

Given n = 6, p = 0.69, and r = 0 or 1:

P = ₆C₀ (0.69)⁰ (1−0.69)⁶⁻⁰ + ₆C₁ (0.69)¹ (1−0.69)⁶⁻¹

P = (1) (1) (0.31)⁶ + (6) (0.69) (0.31)⁵

P = 0.013

The box plot show the price of textbooks at a local high school. What range describe the middle 50% if the price (p) of the textbooks?

Answers

Answer:

See Explanation

Step-by-step explanation:

The question is incomplete, as the box plot is not attached.

However, the interpretation of the question is to determine the inter-quartile range (IQR) ; this represents the middle 50% of scores

To answer this question, I will make use of the attached box plot.

IQR is calculated as:

[tex]IQR = Q_3 - Q_1[/tex]

[tex]Q_1[/tex] and [tex]Q_3[/tex] are represented by the vertical edges of the rectangle in the box plot. [See attachment]

Reading [tex]Q_1[/tex] and [tex]Q_3[/tex], we have:

[tex]Q_1 = 37[/tex]

[tex]Q_3 = 50[/tex]

The IQR is:

[tex]IQR = 50 - 37[/tex]

[tex]IQR = 13[/tex]

Hence, the range that describes the middle 50% of the attached plot is 13
