The answer is 10 x and i think complementary but i could be wrong so you may want someone else to answer that
Answer: -11 meters
Step-by-step explanation:
so for the waters surface, we are going to call that 0. if bob is at 15 meters below 0, then -15+4=-11, so he would be at-11 meters in relation to the waters surface.
Answer:
0.0010,0.2743
Step-by-step explanation:
Given that Stanford–Binet IQ Test scores are normally distributed with a mean score of 100 and a standard deviation of 15
If x represents the scores then
X is N(100,15)
a) See enclosed file
b) Z score =
c) the probability that a randomly selected person has an IQ test score
i. Over 145.
=
ii. Under 91
=
Answer:
-z+4=-4
Step-by-step explanation:
First, you want to move the positive four to the other side to isolate the variable.
-z=-8
You cannot have a negative variable, so divide both sides by 1.
-z/1=-8/1
Your answer would be:
Z=8
Hope this helps!!
Answer:
±√6
Step-by-step explanation:
is your expression first muiltiply out the 10 to get 15n= 10n+10 3/n next subtract 10 n from both sides to get 5n=10+3/n multiply both sides by n to get 5n^2=13 combine both sides and use the quadratic equation to solve to get your solution of ±√6
