The answer is c. y=x-2 i believe
Please restore my faith in humans and try to understand this concept
To solve for the P(54,000≤x≤66000) we proceed as follows:
z-score=(x-μ)/σ
μ-60000
σ-4000
thus:
when x=66,000
z-score=(66000-60000)/4000=1.5
P(z≤1.5)=0.9332
when x=54000
z=(54000-60000)/4000
z=-1.5
P(z≤-1.5)=0.0668
thus
P(54,000≤x≤66000)
=P(z≤1.5)-P(z≤-1.5)
=0.9332-0.0668
=0.8664
Answer: 0.8664
Answer:
1.46
Step-by-step explanation:
First find the the mean score before he made a 90.
Now add the score of 90 and calculate.
Subtract the two scores.
His mean test score increased by 1.46.
Answer:
<h2><u>
154°</u></h2>
Step-by-step explanation:
The central angle and the angle between the tangents are supplementary, so
x + 26° = 180° ( subtract 26° from both sides )
26 - 26 = 0
180 - 26 = <u>154</u>
x = <u>154°</u>
