sattari [20]

Answer:

D. $Q_3=47$

Step-by-step explanation:

We have been given a table that represents the the number of electoral votes California was assigned each decade of the past century. We are asked to find the 3rd quartile of our given data.

The number of votes are: 9, 13, 13, 22, 25, 32, 40, 45, 47, 54, 55.

We will use upper quartile formula to solve our given problem.

$Q_3=\frac{3}{4}*(n+1)^{\text{th term}}$ , where, n represents the number of elements in the data set.

We can see that our data set has 11 data points, so upon substituting n=11 in above formula we will get,

$Q_3=\frac{3}{4}*(11+1)^{\text{th term}}$

$Q_3=\frac{3}{4}*(12)^{\text{th term}}$

$Q_3=3*3^{\text{th term}}$

$Q_3=9^{\text{th term}}$

Now let us count 9th term of our data set. Upon counting our data set from left to right we can see that 9th term of our data set is 47, therefore, 3rd quartile of our given data is 47 and option D is the correct choice.

7x < 10<br> please solve

Anvisha [2.4K]

Answer: The answer would be x < 10/7

Step-by-step explanation:

Rearrange:

Rearrange the equation by subtracting what is to the right of the greater than sign from both sides of the inequality :

7*x (10)>0

Step by step solution :

STEP

Pulling out like terms

1.1 Pull out like factors :

7x - 10 = -1 • (7x + 10)

Equation at the end of step

STEP 2

2.1 Multiply both sides by (-1)

Flip the inequality sign since you are multiplying by a negative number

7x+10 < 0

2.2 Divide both sides by 7

x+(10/7) < 0

Solve Basic Inequality :

2.3 Subtract 10/7 from both sides

x < 10/7

Inequality Plot :

2.4 Inequality plot for

7.000 x - 10.000 > 0

One solution was found :

x < 10/7
