I am not sure but my best guess is that there was 88 questions on the test. If you multiply .98 by 88 (.98*88) it should equal 86.24, which rounded is 86. I am not sure but that is my best guess, I do not know where that 88 came from though, it just popped in my mind. Hope it helps! :)

86/x = 98%
86/x = .98
86 = .98x
86/.98 = x
87.76 = x

round up to 88

1 The legs of a triangle are 6 cm and 8 cm. The hypotenuse is 14 cm. Is it a right triangle?
Vitek1552 [10]

Answer:

this is not a right triangle

Step-by-step explanation:

^  = squared

The formula forthe Pythagorean theorem is    a^+ b^   = c^

If this is a right triangle this must be true

6^ +    8^   =   14^

36 + 64 =  196

100  is not equal to 196

So this is not a right triangle

State whether the data described below are discrete or​continuous, and explain why.The heights (in feet) of different buildingsC
vichka [17]

Answer:  

Option D) The data are continuous because the data can take on any value in an interval

Step-by-step explanation:

We are given the following in the question:

Data: The heights (in feet) of different buildings

Discrete and continuous data:

  • Discrete data is the data that cannot take values in decimals and continuous data can take values in decimals.
  • Continuous data can take any value within an interval.
  • Discrete data cannot take all the value within an interval.
  • Discrete data is counted where as continuous data is measured.

Thus, height is a continuous data since it can take any values within an interval and is measured.

Thus, the correct answer is

Option D) The data are continuous because the data can take on any value in an interval
