Answer:
<h3><u>Firs</u><u>t</u><u> </u><u>q</u><u>uestion</u></h3>
To find ? we use sine
sin ∅ = opposite / hypotenuse
From the question
The hypotenuse is 50
The opposite is 25
So we have
sin ? = 25 / 50
sin ? = 1/2
? = sin-¹ 1/2
<h2>? = 30°</h2>
<h3><u>Sec</u><u>ond</u><u> </u><u>q</u><u>uestion</u></h3>
To find ? we use tan
tan ∅ = opposite / adjacent
From the question
the opposite is 8
the adjacent is 33
So we have
tan ? = 8/33
? = tan-¹ 8/33
? = 13.62
<h3>? = 14° to the nearest degree</h3>
Hope this helps you
Answer:
The standard deviation of the sample mean is 
Step-by-step explanation:
From the question we are told that
The mean is 
The standard deviation is 
The sample size is 
Generally the standard deviation of the sample mean is mathematically represented as
substituting values
22.5 cm* (1 block/ 1.5 cm)= 15 blocks.
The correct answer is B. 15~
If you subtract 2.8 from 0.92, you will get 1.88
Answer:
$11.20 per hat.
and $5.60 per bag
Keisha has $13.20 left over
Step-by-step explanation:
First, I multiplied .70 by 16 and got 11.20 per hat
Then, I multiplied .35 by 16 and got 5.60 per bag
Lastly, I added 11.20 to 5.60 and got 16.80, and subtracted 16.80 from 30 and got 13.20.....
