The answer is C because "dropped" means minus so it is asking: 2-5 which should be -3 not -5.
Answer:
there is no given angle here man
Step-by-step explanation:
Answer:
<ABC = 49°
Step-by-step explanation:
The sum of two supplementary angle is 180. From the diagram, the two angles are 3x+4 and 8x+11. IF this two angles are supplementary then;
3x+4+8x+11 = 180
11x+15= 180
11x = 180-15
11x = 165
x = 165/11
x = 15
From the attached diagram, <ABC = 3x+4
<ABC = 3(15)+4
<ABC = 45+4
<ABC = 49°
Answer:

Step-by-step explanation:
We have been given that human body temperatures have a mean of 98.20° F and a standard deviation of 0.62°. Sally's temperature can be described by z = -1.5.
To find Sally's temperature we will use z-score formula.
, where
= Mean,
= Standard deviation.
Let us substitute our given values in z-score formula.

Multiply 0.62 to both sides of equation.


Add 98.20 to both sides of equation.


Therefore, Sally's temperature will be 97.27 degrees Fahrenheit.
