Mazyrski [523]3 years ago
6 0

Answer:

Step-by-step explanation:

x² + 6x - 8 = 4x + 7

x² + 2x - 15 = 0

(x+5)(x-3) = 0

x = -5, 3

y = 4x + 7 = -13, 19

-13 + 19 = 6

Given data is 54, 59, 35, 41, 46, 25, 47, 60, 54, 46, 49, 46, 41, 34, 22

Arranging it in increasing order:

22 25 34 35 41 41 46 46 46 47 49 54 54 59 60

Number of data items, n=15.

Finding Median, First Quartile, and Third Quartile

Finding\;\;median\\M=\frac{n+1}{2}th\;\;term =\frac{15+1}{2}=8th\;\;term\;\; i.e. \;\;46

22 25 34 35 41 41 46 46 46 47 49 54 54 59 60

Now finding First Quartile from set: 22 25 34 35 41 41 46

Q₁ = middle term i.e. 35

Now finding Third Quartile from set: 46 47 49 54 54 59 60

Q₃ = middle term i.e. 54

So we have Q₁ = 35, M = 46, and Q₃ = 54. Lower bound is 22 and Upper bound is 60.

While drawing the given data on number line and marking First quartile, Median, Third quartile on number line. We can clearly observe that option A matches with given data points.

Hence, option A i.e. Box-plot A is the correct choice.

Renee, Susan, and Martha will share the cost to rent a vacation house for a week. Renee will pay 40 percent of the cost. What fr
Rom4ik [11]

Answer:

Amount paid by Martha = $200

Amount paid by Renee = $320

Amount paid by Susan = $280

Step-by-step explanation:

Here, the given question is INCOMPLETE.

Renee, Susan and Martha will share the cost to rent a vacation house for a week. Renee will pay 40% of the cost. Susan will pay 0.35 of the cost. Martha will pay the remainder of the cost. If the cost to rent the vacation house is $800, how much will each person pay?

Here, the total cost of the vacation  = $800.

Renee pays 40% of the cost.

Calculating 40% of $800, we get:

\frac{40}{100} \times 800 = 320

So, Renee pays a total of $320 in the cost of vacation.  ... (1)

Susan pays 0.35 = 35 %  of the cost.

Calculating 35% of $800, we get:

\frac{35}{100} \times 800 = 280

So, Susan pays a total of $280 in the cost of vacation.  ... (2)

Now, The amount paid by { Renee + Susan  + Martha} = $800

⇒ $320 + $280 + Amount paid by Martha  = $800

⇒Amount paid by Martha = $800 - $600 = $200

Hence, Amount paid by Martha = $200

Amount paid by Renee = $320

Amount paid by Susan = $280
