The temperature is 2 degrees and drops to -15 degrees overnight. Write and then evaluate a subtraction expression to determine t
KiRa [710]

Answer:

-17 degrees

Step-by-step explanation:

Given that:

Initial temperature = 2 degrees

Final temperature = -15 degrees

To Determine:

The change in temperature.

Solution:

First of all, let us have a look at the method for calculating the change in any quantity.

Let the initial quantity = a

Let the final quantity = b

Change in quantity = Final quantity - Initial quantity = b - a

Here, we are given the quantity as temperature.

where a = 2 degrees and

b = -15 degrees

Therefore, the change in temperature = -15 - 2 = \bold{-17} <em>degrees</em>

The grades on a history midterm at Almond are roughly symmetric with y = 85 and o = 2.0.
Alik [6]

Answer:

The z-score for Michael's exam grade is 0.50

Step-by-step explanation:

Data

  • mean, μ = 85
  • standard deviation, σ = 2.0
  • Michael's exam grade is the value of interest, x = 86

From definition, z-score is  computed as follows:

Z = (x - μ)/σ

Z = (86 - 85)/2.0

Z = 0.50
