Answer:

[tex]\boxed {\boxed {\sf D. \ 23.5}}[/tex]

Step-by-step explanation:

The median is the number in the middle of a set of data. To find, we place the numbers in order from least to greatest and pick the middle number.

The data set is:

This is already in order from least to greatest, so we can begin removing numbers from each side of the list until the middle is reached.

Now we have 2 numbers that are in the middle. To find the median, we take the mean or average of these 2 numbers. Add them together, then divide by 2.

The median of this data set is 23.5 and choice D is correct.

The sales in 2007 will be $752.1 billion

The Midpoint Formula to estimate the sales (in billions of dollars) in 2017 will be calculated as the sales in both years divided by 2 and this will be:

= [2016 sales + 2018 sales} / 2

= [$483.9 billion + $536.4 billion] / 2

= $1020.3/2

= $752.1 billion

Therefore, the sales in 2017 is $752.1 billion.

Answer:

Ada is correct.

Step-by-step explanation:

Problems with Naman:

Naman is supposed to follow PEMDAS, which is the order of operations, and stands for:

Parenthesis

Exponents (& Roots)

Multiplications

Division

Addition

Subtraction

~

The mistake: Naman moved +6 to the left and added it to the 2 located on the left side of the expression. You cannot do that, as it breaks the law of PEMDAS. On the other hand, Ada did the correct thing, which was to distribute 2 to all terms within the parenthesis (as one term in the parenthesis has a variable, and the other is a constant, meaning that they cannot be combined). This leads to Naman not doing the rest of the question correct.

Next, Ada correctly combined the two constants, which resulted in 0. 0 means nothing, therefore the placeholder is not needed. Therefore, 8x is the final answer.

Answer:

12,500 people went to the fair.

Step-by-step explanation:

Set up an equation:

Variable x = number of people who went to the fair

12/100 = 1500/x

Cross multiply:

12 × x = 100 × 1500

12x = 150000

x = 12500

Check your work:

12500 × 12%

Convert percentage into a decimal:

12500 × 0.12

1500

1500 people received water bottles so this is correct!

Answer:

The ratio of oranges to apples is 2:3.

Step-by-step explanation:

Answer:

If they spent the same amount of money, then an apple is $2 less then an orange.

Step-by-step explanation:

So, we already know that Lu has 12 apples and oranges. We also know the ratio: 3 apples:2 oranges.

So, in order to see the cost of one apple and one orange, we need to divide the number 12 by these numbers.

12 ÷ 3 = $4 per apple

12 ÷ 2 = $6 per orange

Therefore, if they spent the same amount of money, (which can only give them 3 apples for $12, or 2 oranges for $12), then an apple is $2 less then an orange.

Answer:

-9j=6j-2(5j + 5)

-9j-6j=-2(5j+5)

-15j=-10j -10

-15j+10j=-10

-5j=-10

-5j/-5 =-10/-5

j=2

Step-by-step explanation:

-9j = 6j - 2 (5j + 5)

-9j = 6j - 10j - 10

-9j = -4j - 10

-9j + 4j = -10

-5j = -10

j = -10 / -5

j = 2

Answer:

16

Step-by-step explanation:

2+6=8

8+10=18

18+14=32

6+4=10 10+4=14

an+1=an+(2+4n)

a7=a6+26=72+26=98

a8= a7+30= 98+30=128

a9=a8+34=128+34= 162

a10=a9+38= 162+38=200

a11=a10+42= 242

a12=242+46=288

a13=288+50= 338

a14=338+54= 392

a15=392+58= 450

a16= 450+62=512

This is an exponential growth problem.

Step by step process:

Let's solve for x.

y−3=2(x+1)

Step 1: Flip the equation.

2x+2=y−3

Step 2: Add -2 to both sides.

2x+2+−2=y−3+−2

2x=y−5

Step 3: Divide both sides by 2.

2x/2=y−5/2

x=1/2y+(−5/2)

Answer: x=1/2y+(−5/2)

Let's solve for y.

y−3=2(x+1)

Step 1: Add 3 to both sides.

y−3+3=2x+2+3

y=2x+5

Answer:

y=2x+5
