You must first normalize this in order to use a Z-score table. To convert what you have into a Z score you must use this formula: (x- mean) /standard deviation. In your case (334-310)/12=2. So now you want the probability that a score is greater than 334, which in turn means you want P(Z>2)=1-P(Z<2)=1-.9772=0.0228=2.28%.
Answer:
17 X 8 = 136^
area of a triangle
0.5 X b X h
0.5 X 8 X 17 = 68 cm^
136 - 68 = 68 cm^
total shaded area = 68 cm^
Answer:
D
Step-by-step explanation:
The absolute value function always returns a positive value, that is
| - a | = | a | = a
Given
8 - | 2g - 5 | ← substitute g = - 3.5 into the expression
= 8 - | - 7 - 5 |
= 8 - | - 12 |
= 8 - 12
= - 4 → D
Answer:

Step-by-step explanation:
100% means total amount of people surveyed, which is 300 people total.
We're looking for females who own a blue car, so that's 75 people out of 300.
75/300 = 0.25
Convert the decimal to percent by moving decimal 2 places to the right
Answer is 25%
