Answer:

$\huge\boxed{x$

Step-by-step explanation:

$-9.4>1.7x+4.2\qquad\text{subtract 4.2 from both sides}\\\\-9.4-4.2>1.7x+4.2-4.2\\\\-13.6>1.7x\qquad\text{divide both sides by 1.7}\\\\\dfrac{-13.6}{1.7}>\dfrac{1.7x}{1.7}\\\\-8>x\to\boxed{x$

Answer:

a. The general trend would be skewed left.

b. The median is 3.

c. The mean is 3.3.

d. The mean would be affected more.

Step-by-step explanation:

a. The value of this graph is shown as left, and since the graph gets bigger the farther right you go, it would be skewed more to the left.

b. 1, 1, 2, 2, 2, 3, 3, 3, 4, 4, 5, 6, 7

(cross off all of the numbers except the one in the middle)

c.1+1+2+2+2+3+3+3+4+4+5+6+7=43/13(or in other words, how many values they are)=3.307...=3.3

d. If a 15 was added to this value, the median would still be 3, but the mean would push the sum of all values to 58, and, when divided by 14, it would be around 4.1.

PLEASE HELP what is 30th term of -12, -3, 6, 15

hoa [83]

Answer:

249

Step-by-step explanation:

We can see that the difference of every term in the given sequence is 9, because -12 + 9 = -3, -3 + 9 = 6 and 6 + 9 = 15. We may therefore assume that the sequence is arithmetic (a fancy word of saying that a sequence is increasing with a constant value every term).

Since the difference of every term is 9, we know that the explicit form of the sequence (where the value of every term is expressed in terms of the term number) is in the form $9n+c$ , where $n$ is the term number and $c$ is a constant we are going to figure out right now.

We know that the first term of the sequence is -12, so we see that $9(1) + c = -12$ and hence $c=-21$ . Therefore, the 30th term of the sequence is $9(30) - 21 = 249$ .

Isabelle is mixing red paint with blue paint to make purple paint. She adds of a fluid ounce of red to of a fluid ounce of blue

Paha777 [63]

Answer:

it seems that to make purple paint you take 1 part blue and 1 part red so to make 3 fluid ounces of purple paint you would need 1.5 fluid ounces of red paint and 1.5 fluid ounces of blue paint.

Write the number in scientific notation: 60,000

Natasha_Volkova [10]

6×10^4
We use 6 because the # has to be greater than or equal to 1 but less than or equal to 10.
10^4=10000
10000×6=60000
