Answer:
No, Jill is incorrect because 23/1000 and 0.23 are not equivalent. But 23/100 is equivalent to 0.23 and 0.023 is equivalent 23/1000
Given that mean=56.1 and standard deviation=8.2, P(x>67.5) will be found as follows:
The z-score is given by:
z=(x-μ)/σ
thus the z-score will be given by:
z=(67.5-56.1)/8.2
z=11.4/8.2
z=1.39
thus
P(z=1.39)=0.9177
thus:
P(x>67.5)=1-P(z>0.9177)
=1-0.9177
=0.0823
Answer: A. 0.0823
Answer:
193.2
Step-by-step explanation:
To solve the triangle:
5.2 × 6= 31.2
You would normally find half of that since it's a triangle but there are two triangles, so each would equal half of 31.2 but if you add both halves that just equals 31.2.
Square one:
9 × 6= 54
All three squares are equal since they have the same measurements.
54 + 54 + 54= 162
162 + 31.2= 193.2
Answer:
-(-9) is 9
Step-by-step explanation:
-(-9)
(when there are two negatives multiplyed with eachother, the product will be postive)
+ 9
+ 9 = 9
