Answer:
50 = 2
Step-by-step explanation:
which by definition equates to 68+1
So taking this as if there are 13 dozens of cookies. First we do 13 times 12 which would be 156 cookies in total. Then 156 cookies times 2.08 is 324.48
The proportion who had<em> no such experience</em> was 0.362
<h3>
How the find the proportion?</h3>
Given:
Total sample: 3887
No that had no opinion: 1407
No that had at least one experience: 2480
Therefore, to find the proportion who had<em> no such experience</em> is:
Sample number/Total sample
1407/3887
=0.362

Answer:
x = 68°
explanation:
As its a right angle triangle, it has 90° angle.
solve:
x + 22° = 90°
x = 90° - 22°
x = 68°
Answer:
Angle B = 106.6 degrees
Step-by-step explanation:
b^2= a^2+c^2-2*a*c*cosB
9*9 = 4*4 + 7*7 - 2*7*4*cosB
81= 16+49-56cosB Subtract 16 and 49 from both sides
16= -56cosB Divide by -56 on both sides.
cosB= -16/56 Take the arccosine of both sides
B=arccos(-16/56)
B= 106.6
