Step-by-step explanation:
3 nights obvs idk how you couldn't get the answer
First, we get the standard error of the mean using
σm = σ / √N
= 5 / √100
= 0.5
Next, we subtract and add 1.96 standard deviations from the mean (since the confidence interval is 95%). So,
8 ±1.96 (0.5)
= 8 <span>± 0.98
The answer is
</span>E) 8±0.98
Answer: angle A=40, Angle B=74, Angle C=66
Step-by-step explanation:
We all know that a triangle has 180 degrees.
3x-8+5x-6+4x+2=180
12x-12=180
12x=180+12
12x=192
x=16.
∠A=2(16)+8=40
∠B= 90-16=74
∠C = 5(16) -14= 66
