Answer:
2:7
Step-by-step explanation:
4+10=14
The least common factor is 2.
4/2=2
14/2=7
The empirical rule states that at 95% the measurements would be within 2 standard deviations of the mean.
You are given a mean of 68 inches and a standard deviation of 4.
2 times the standard deviation = 2 x 4 = 8
So 95% of the heights would be between 68-8 = 60 inches and 68+8 = 76 inches.
The answer is negative 6 or -6 because-2 x 3 is 6
Answer:
sin Z = 4/5
sin C = 24/25
cos A= 4/5
tan Z = 4/3
Step-by-step explanation:
<h3><u>1</u><u>.</u><u>)</u></h3>
sin Z = O/H
sin Z = 36/45 = 4/5
sin Z = 4/5
<h3>
<u>2</u><u>.</u><u>)</u></h3>
sin C = O/H
sin C = 48/50 = 24/25
sin C = 24/25
<h3>
<u>3</u><u>.</u><u>)</u></h3>
cos A = A/H
cos A = 40/50 = 4/5
cos A= 4/5
<h3>
<u>4</u><u>.</u><u>)</u></h3>
tan Z = O/A
tan Z = 24/18 = 4/3
tan Z = 4/3
