Which expression represents the shaded length of the number line below? Choose 1 answer: Choose 1 answer: (Choice A) A 34×32\dfr

Anit [1.1K]

Answer:

$Expression = \frac{2}{3} * \frac{5}{4}$

Step-by-step explanation:

See attachment for number line

From the attachment, we have the following details:

The first shade of blue covered 10 blocks

The second shade of blue covered 5 further blocks which totaled to 15

So, the fraction of the blue blocks is:

$Blue = \frac{10}{15}$

Divide fraction by 5/5

$Blue = \frac{10/5}{15/5}$

$Blue = \frac{2}{3}$

Also from the attachment:

The shaded block stopped at the fraction:

$Shaded = \frac{5}{4}$

So, the expression that represents this scenario is:

$Expression = Blue * Shaded$

$Expression = \frac{2}{3} * \frac{5}{4}$

Answer:

$26.5265$

Step-by-step explanation:

Confidence Interval

When the population standard deviation $\sigma$ is known, the formula for a confidence interval for a population mean $\bar x$ is:

$\displaystyle \bar x \pm z\frac{\sigma}{\sqrt{n}}$

Where n is the sample size and z is the corresponding z-value from the standard normal distribution for the selected confidence level. The value of z for a 95% confidence interval is z=1.96. The rest of the values are

$\bar x=28.2,\ \sigma=2.7, \ n=10$

Calculating the confidence interval

$\displaystyle 28.2 \pm 1.96\frac{2.7}{\sqrt{10}}$

$\displaystyle 28.2 \pm 1.6735$

Or, equivalently

$26.5265$
