Answer:

(3 \times 10)^{ - 12}  =  \frac{1}{(3 \times 10)^{12} }

Step-by-step explanation:

When we multiply two equal values with different power, we sum the two powers.

Negative power is equ to 1 over the value with positive power:

(3 \times 10)^{ - 15}  \times (3 \times 10) ^{3}  =  \\ (3 \times 10) ^{ - 15 + 3}  = (3 \times 10) ^{ - 12}  =  \\  =  \frac{1}{ {(3 \times 10)}^{12} }

Triangle ABC was dilated by 50%. What is the relationship between AC and A'C'?
Elina [12.6K]

Answer:      

The length of segment AC is two times the length of segment A'C'

Step-by-step explanation:

we know that

If two figures are similar, then the ratio of its corresponding sides is proportional and this ratio is called the scale factor

Let

z ----> the scale factor

A'C' ----> the length of segment A'C'

AC ----> the length of segment AC

so

z=\frac{A'C'}{AC}                        

we have that

z=50\%=50/100=\frac{1}{2} ---> the dilation is a reduction, because the scale factor is less than 1 and greater than zero

substitute

\frac{1}{2}=\frac{A'C'}{AC}                

AC=2A'C'

therefore

The length of segment AC is two times the length of segment A'C'

The heights of a random sample of 100 women are recorded. The sample mean is 65.3 inches and the sample standard deviation is 3
Keith_Richards [23]

Answer: B. 65.3\pm(2)(0.3)

Step-by-step explanation:

The confidence interval for the population mean is given by :-

\overline{x}\pm z_{\alpha/2}\dfrac{\sigma}{\sqrt{n}}

Given : Sample size : n= 100

Sample mean : \overline{x}=65.3\text{ inches}

Standard deviation: \sigma=3 \text{ inches}

Level of confidence = 0.95

Significance level : \alpha=1-0.95=0.05

Critical value : z_{\alpha/2}=1.96

Then, 95% confidence interval for the population mean will be :-

65.3\pm (1.96)\dfrac{3}{\sqrt{100}}\\\\\approx65.3\pm(2)(\dfrac{3}{10})=65.3\pm(2)(0.3)
