step one and two is wrong because when you're distributing this equation u should get -24+4y+4=-4 u caculate and then u move the constant to the right side and caculate again then divide

the table above represents what type of function x 0,1,2,3 y -6 , -5 ,2 ,21 a.) linear b.) neither linear or nonlinear c.) linea

Juliette [100K]

Answer:

Step-by-step explanation:

Given the table

$\begin{array}{ccccc}x&0&1&2&3\\ \\y&-6&-5&2&21\end{array}$

The change in x is

$1-0=2-1=3-2=1$

The change in y is

$-5-(-6)=1\\ \\2-(-5)=7\\ \\21-2=19$

Since for the same change in x, the change in y is different, given table represents nonlinear function.

A triangle has an angle that measures 90°. The other two angles are in a ratio of 2:7. What are the measures of those two angles

marin [14]

Answer:

70° and 20°

let the other 2 angles be 7x and 2x

90+7x+2x=180

9x=180-90

x=90/9

x=10

7x=7x10

2x=2×10

Answer:

Standard deviation = 5.1

Mean = 13

Median = 14

Step-by-step explanation:

The sample standard deviation measures the spread of a data distribution of the sample. It is usually used to estimate the population standard deviation

The mean of a set of numbers is the sum divided by the number of terms.

Arrange the data in an ascending order and the median is the middle value. If the number of values is an even number, the median will be the average of the two middle numbers.
