X = price of desktop computer (dollars)
y = price of laptop computer (dollars)

y = x + 400
x * 0.07 + y * 0.08 = 275

x * 0.07 + (x + 400) * 0.08 = 275
0.07x + 0.08x + (400 * 0.08) = 275
0.15x + 32 = 275
0.15x = 275 - 32
0.15x = 243
x = 243 / 0.15
x = 1620

y = 1620 + 400
y = 2020

Please help... How many odd perfect squares are between 5 and 211?
frez [133]

Answer:

we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Step-by-step explanation:

Let us check by taking squares

  • 3² = 9
  • 5² = 25
  • 7² = 49
  • 9² = 81
  • 11² = 121
  • 13² = 169

As taking 14² = 256 would exceed 211, and 1² = 1 is smaller than 5.

Therefore, we conclude that the total number of perfect odd squares between 5 and 211 will be: 6

Which of the following describes the probability distribution below?
Serhud [2]

Answer:

B. Median is greater than the mean and the majority of data points are to the right of the mean.

Step-by-step explanation:

Mean = sum(x × p(x))

= (1×0.1)+(2×0.15)+(3×0.2)+(4×0.45)+(5×0.1)

= 3.3

Probability of more than 3.3 is:

0.45 + 0.1 = 0.55 > 0.5
