To calculate the mean weights of the potatoes, the weights are all added and divided by the number of potatoes.
The sum of all the potatoes - <span>5 + 8 + 9 + 11 + 7 + 7 + 8 + 9 + 12 + 7 = 83
the number of potatoes - 10
we have to divide the sum of weights by 10
Mean weight = 83/10 = 8.3
Rounded off to the nearest ounce - 8 </span>ounces

The ratio of violinists to cellists in the school orchestra must always be 7:3. If the school orchestra has 21 violinists, what

Papessa [141]

Given:

Violinists : Cellists = 7:3.

Number of violinists in the school orchestra = 21

To find:

The combined number of cellists and violinists.

Solution:

Let the number of violinists and cellists in the school orchestra are 7x and 3x respectively.

Then, combined number of cellists and violinists is

$\text{Combined number of cellists and violinists}=7x+3x$

$\text{Combined number of cellists and violinists}=10x$ ...(i)

Number of violinists in the school orchestra = 21

$7x=21$

Divide both sides by 7.

$x=3$

Now, the combined number of cellists and violinists is

$\text{Combined number of cellists and violinists}=10(3)$ [Using (i)]

$\text{Combined number of cellists and violinists}=30$

Therefore, the combined number of cellists and violinists is 30.

Which table represents the same linear relationship as y = 3x - 2?

Trava [24]

Answer:

Table 4 represents the same linear expression as y = 3 x - 2.

Step-by-step explanation:

Here, the given expression is y = 3 x -2

So now check the any random pair of each table by putting in the given equation.

<u>TABLE 1 : (2,-5)</u>

y = 3x -2 ⇒ -5 = 3(2) -2

or, -5 = -4 , NOT POSSIBLE

<u>TABLE 2 : (0,3)</u>

y = 3x -2 ⇒ 3 = 3(0) -2

or, 3 = -2 , NOT POSSIBLE

<u>TABLE 3 : (1,2)</u>

y = 3x -2 ⇒ 2 = 3(1) -2

or, 2 = 1 , NOT POSSIBLE

<u>TABLE 4 : (1,1)</u>

y = 3x -2 ⇒ 1 = 3(1) -2

or, 1 = 1 , POSSIBLE

checking for (2,4)

4 = 3(2) - 2 ⇒4 = 4 POSSIBLE

Here, table 4 satisfies the given points in the expression y = 3x -2

Hence, it represents the same linear expression .
