Answer:
d. 0.4013
Step-by-step explanation:
Half of the area under the normal curve is found to the left of the midpoint, where z=0. For negative values of z, the area under the curve is less than half.
Area under a normal curve is always a positive value between 0 and 1, so will never be negative.
The only value that can be an area in a left-hand tail is 0.4013.
_____
<em>Additional comment</em>
That value corresponds to z ≈ -0.25.
For this, we are just going to plug in -9 for every x and then solve the equation:




Now we know that q(-9) is equal to 566.
Answer:
C
Step-by-step explanation:
3/5 + 1/4 = 0.85
0.85 as a fraction is 17/20
So the answer is C
76% of 200<span> = </span><span>152</span>76/100 * 200
<span>
= 76*200/ 100 = 152</span>
The Answer Would Be 3/7
Hope This Helps :)
