Answer:
confidence interval
Step-by-step explanation:
confidence interval is defined that range of interval that defined degree of certainty and uncertainty for a given sampling method.
it is a probability of given sample which state that particulars parameters are lie between two set of limits.
examples - 95 % confidence interval states that there are 95% probability that given sample contain true value.
<span>The vertices of are D(7, 3), E(4, -3), and F(10, -3)
Prove tat DE = DF
Length of a segment = </span>√[(x₂ - x₁) +(y₂ -y₁)]
DE = √([4-7)² + (-3 -3)²] = √45 = 3√5
DF = √[(10-7)² +(-3 -3)²] = √45 b= 3√5
Hence DE = DF = 3√5 and DEF is ISOSCELES
Answer:
1.5
Step-by-step explanation:
I did it
Answer:
true
Step-by-step explanation:
* substitute 30 for x *
we're left with 15 < 20 which is true
I think it is D but if it is not I’m sorry
