6/12=X/18
Using the ratio of 18:12, you multiply 18/12 with 6, which equals 9.

Answer:

NJ=9

Step-by-step explanation:

We have been given that MN and KL are parallel. If JM = 6, MK = 12, and LN = 18. We are asked to find the measure of NJ.

Since line MN is parallel to KL, so triangle JMN is similar to JKL.

We know that corresponding sides of similar triangle are proportional. We will use proportion to solve for NJ as:

\frac{NJ}{LN}=\frac{JM}{MK}

\frac{NJ}{18}=\frac{6}{12}

Multiplying both sides by 18, we will get:

\frac{NJ}{18}*18=\frac{6}{12}*18

NJ=\frac{1}{2}*18

NJ=9

Therefore, measure of NJ is 9 units.

Answer:

Explained below.

Step-by-step explanation:

The data provided is for the dying time of four different types of paint.

One-way ANOVA can be used to determine whether all the four paints have the same drying time.

Use Excel to perform the one-way ANOVA.

Go to Data → Data Analysis → Anova: Single Factor

A dialog box will open.

Select the data.

Select "Grouping" as Columns.

Press OK.

The output is attached below.

The required values are as follows:

(1)

Sum of Squares of Treatment (Between Subjects):

SST = 330

(2)

Sum of Squares of Error (Within Subjects):

SSE = 692

(3)

Mean Squares Treatment (Between Subjects):

MST = 110

(4)

-(4k^2-13k-12)+5k^2-8k How would I be able to write this in standard form with the greatest exponent being first.
aliina [53]

Answer:

Step-by-step explanation:

Negative sign is outside the parenthesis. So, each term of (4k² - 13k -12) should be multiplied by (-1)

-(4k² - 13k -12) + 5k² - 8k = 4k²*(-1) - 13k*(-1) - 12*(-1) + 5k² - 8k

                                        = -4k² + 13k + 12 +5k² - 8k

Combine like terms,

                                        = -4k² + 5k² + 13k - 8k + 12

                                       = k² + 5k + 12

Like terms are the terms with same variable with same exponent.

(-4k² ) and 5k² are like terms

13k and (-8k) are like terms
