The answer is 3.92 and I think that is the answer
Answer:
7 in
Step-by-step explanation:
Process of elimination. It can’t be 9 or 10, because 9+9=18 and 10+10=20 (they're more than 16). 8+8=16 exactly, but there’s no room in 16 for the width. Therefore, it’s 7 because 7+7=14

Answer:
Step-by-step explanation:
We want to determine a 80% confidence interval for the mean mercury concentration of water samples
Number of samples. n = 4
Mean or average = 0.470 cc/cubic meter
Standard deviation, s = 0.0581
For a confidence level of 80%, the corresponding z value is 1.28. This is determined from the normal distribution table.
We will apply the formula
Confidence interval
= mean +/- z ×standard deviation/√n
It becomes
0.470 +/- 1.28 × 0.0581/√4
= 0.470 +/- 1.28 × 0.0566/2
= 0.470 +/- 0.036
The lower end of the confidence interval is 0.470 - 0.036 =0.434
The upper end of the confidence interval is 0.470 + 0.036 =0.506
In conclusion, with a 80% confidence interval, the mean lead mean mercury concentration of the water samples is between 0.434 cc/cubic meter and 0.506 cc/cubic meter
∠13 = 70.5° [Vertically Opposite angles]
∠13+∠14=180° [Linear pair]
70.5°+∠14=180°
∠14=180-70.5
∠14=109.5
∠15=∠14=109.5 [Vertically opposite angles]
∠13=∠12= 70.5° [Co-interior angles]
∠12=∠10= 70.5° [Vertically Opposite angles]
∠14=∠11=109.5 [Co-interior angles]
∠9=∠11= 109.5 [Vertically opposite angles]
∠13=∠7= 70.5° [Alternate interior angles]
∠7=∠5=70.5° [Vertically Opposite angles]
∠7+∠8=180° [Linear Pair]
70.5+∠8=180
∠8=180-70.5
∠8=109.5°

Maria- y= 10x+5
In these equations y symbolises all the money they have after the x amount of days so by the x you put the amount of money they put in their bank every day and at the end add the amount of money they put in the bank at the start.
