I think that she should bring three packs. 6 hours=360 minutes. 360/45=8. 345x8=2760. 2760/3=920 and 310x3=930. :)
Answer:
x=40
Step-by-step explanation:
30x-215=985
Add 215 to each side
30x -215+215 =985+215
30x = 2100
Divide each side by 30
30x/30 = 1200/30
x=40
The value of b is 61°.
you solve by doing this:
add up the two given angles, 58° and 61° to get 119°. then you subtract from 180° to get 61.
The confidence interval in the form p+E is p ± E = 0.7725 ±0.435
<h3>How to rewrite the
confidence interval?</h3>
The confidence interval is given as:
0.555< p < 0.99
To rewrite the above expression in the form p+E, we use the following equations
p = (0.99 + 0.555)/2 = 0.7725
E = (0.99 - 0.555) = 0.435
So, we have:
p ± E = 0.7725 ±0.435
Hence, the confidence interval in the form p+E is p ± E = 0.7725 ±0.435
