Each of 6 samples has a different standard deviation. How many of the 6

ivann1987 [24]

The number of six samples that could belong to the same population is equivalent to six.

Option A is the correct answer.

<h3>What is the standard deviation?</h3>

The standard deviation is the indicator to determine the variation between the set of amounts as given in the statistical information.

The population is referred to as the entire information being prescribed in data relating to any concept. If the number of samples in a population is 10, then the samples in the same population will also be 10. This shows the number of samples is always equal to the samples in the same population.

Therefore, the six samples belong to the same population comprising of six samples having varied standard deviations.

A child riding a bicycle at 15 m/s accelerates at 3. 0 m/s/s for 4. 0 s. What is the child's speed at the end of this 4. 0 s int

mamaluj [8]

Answer:

The final speed of bicycle would be <u>27 m/s</u>².

Step-by-step explanation:

<u>Given</u> :

$\small\red\bull$ Initial velocity (u) = 15 m/s
$\small\red\bull$ Acceleration (a) = 3.0 m/s²
$\small\red\bull$ Time = 4 seconds

<u>To</u><u> </u><u>Find</u> :

$\small\red\bull$ Final velocity (v)

<u>Using</u><u> </u><u>Formula</u> :

$\longrightarrow{\pmb{\sf{v = u + at}}}$

$\small\blue\star$ v = final velocity
$\small\blue\star$ u = initial velocity
$\small\blue\star$ a = acceleration
$\small\blue\star$ t = time taken

<u>Solution</u> :

Substituting the values in the formula to find the final velocity :

$\longrightarrow{\sf{v = u + at}}$

$\longrightarrow{\sf{v = 15 + (3.0 \times 4)}}$

$\longrightarrow{\sf{v = 15 + (3 \times 4)}}$

$\longrightarrow{\sf{v = 15 +(12)}}$

$\longrightarrow{\sf{v = 15 +12}}$

$\longrightarrow{\sf{v = 27 \: {m/s}^{2}}}$

$\star{\underline{\boxed{\red{\sf{v = 27 \: {m/s}^{2}}}}}}$

Hence, the final speed of bicycle would be 27 m/s².
