Let's see which of these best measures the data.
The mean is the average, or the sum of all numbers divided by the total numbers there are.
4.8 + 3 + 2.7 + 4.4 + 4.8 + 9.9 = 29.6
There are 6 numbers total.
29.6/6 = 4.93.
The mean is 4.93.
Let's try our median. The median is the middle number of a sequence listed from least to greatest. I will make the list for you.
2.7, 3, 4.4, 4.8, 4.8, 9.9.
Cross out the smallest number with the greatest number.
3, 4.4, 4.8, 4.8.
4.4, 4.8.
Since we do not have a middle number, we must see what number is in the middle of 4.4, and 4.8. To determine this, we must average. Add 4.4 and 4.8, then divide by 2.
9.2/2 = 4.6.
4.6 is our median.
The mode is the number that appears the most, so let's find the number that is the most frequent.
4.8 is our mode.
The best number that will fit in this to make it work out is 4.6.
The median is your answer, B.)
I hope this helps!

A beach ball has a mass of 5 g and a volume of 20 cm3. What is the object's density? A. 4 g/cm3 B. 100 g/cm3 C. 0.25 D. g/cm3 4
Triss [41]
<h2>Hello!</h2>

The answer is:

C.  0.25\frac{g}{cm^{3} }

<h2>Why?</h2>

The density is the relation between the mass and the volume of an object. We are given four options to chose, and we can find the correct one by doing the following calculations:

Density=\frac{mass}{volume}=\frac{5g}{20cm^{3}}=0.25\frac{g}{cm^{3}}

So, the correct options is C.  0.25\frac{g}{cm^{3} }

Have a nice day!

Which is an equivalent expression for 21a+35?
ki77a [65]

Answer:

7(3a + 5)

Step-by-step explanation:

Rewrite 21 as 7 · 3

Rewrite 35 as  7 · 5

Therefore,

⇒ 21a + 35 = 7 · 3a + 7 · 5

Factor out common term 7:

⇒ 7 · 3a + 7 · 5 = 7(3a + 5)

HELPPP ASAPP Bernie's Bars has determined that a granola bar measuring 3 inches long has a z-score of +1 and a granola bar measu
Len [333]

Answer:

Standard deviation of the length of granola bars produced at Bernie's Bars is 0.50      

Step-by-step explanation:

We are given the following information in the question:

Formula:

z_{score} = \displaystyle\frac{x - \mu}{\sigma}

where,

μ is the mean and σ is the standard deviation.

Putting the values we get:

\displaystyle\frac{ 3- \mu}{\sigma} = 1\\\\3 = \sigma + \mu\\\\\displaystyle\frac{ 3.5- \mu}{\sigma} = 2\\\\3.5 = 2\sigma + \mu

Solving the two obtained equations:

Subtracting the two obtained equation, we have:

3.5-3 = \mu + 2\sigma - \mu -\sigma\\\sigma = 0.5

Hence,  standard deviation of the length of granola bars produced at Bernie's Bars is 0.50
