Lisa [10]

Answer:

Step-by-step explanation:

$sin\theta =\frac{5}{13}\\ \\ \theta =sin^{-1}\frac{5}{13}\\ \\ \theta =22.62^o\\ \\ \\ a=90-22.62\\ \\ a=67.38^o\\ \\ \\ 13^2=5^2+x^2\\ \\ x^2=169-25\\ \\ x^2=144\\ \\ x=\sqrt{144}\\ \\ x=12$

In a study of crime, the FBI found that 13.2% of all Americans had been victims of crime during a 1-year period. This result was

Mkey [24]

Answer: The lower bound of confidence interval would be 0.116.

Step-by-step explanation:

Since we have given that

p = 13.2%= 0.132

n = 1105

At 90% confidence,

z = 1.645

So, Margin of error would be

$z\sqrt{\dfrac{p(1-p)}{n}}\\\\=1.645\times \sqrt{\dfrac{0.132\times 0.868}{1152}}}\\\\=0.0164$

So, the lower bound of the confidence interval would be

$p-\text{margin of error}\\\\=0.132-0.0164\\\\=0.116$

Hence, the lower bound of confidence interval would be 0.116.

It took Ciera 24 minutes to drive 18 miles. It took chains of one hour to drive 46 miles. Who is driving at a faster rate?

katen-ka-za [31]

Answer:

Ciera is driving at a faster rate.

Step-by-step explanation:

You calculate speed, by dividing distance by time.

So 18 divided by 24 is 0.75. That is Ciera's speed.

And then to calculate the other person/thing's speed you have to divide 46 by 60 minutes (equal to one hour). The speed calculates to 0.7666666667

Therefore, Ciera is driving faster.
