Tan, since you only have the two smaller sides

We need to figure out which trig function we can use when we can one angle, its adjacent side, and its opposite side

sin(x) = opposite/hypotenuse
cos(x) = adjacent/hypotenuse
tan(x) = opposite/adjacent

So we know we have to use C: tangent

Hope this helps<span />

Answer:

The first one : decay

The second one : growth

When the argument of the exponential expression is bigger that 1 then it represents a growth

When it's less than 1 and above 0 then it's a decay

The data set shown below has an outlier. Determine the outlier and then answer the questions as to what happens to the median, m

Pachacha [2.7K]

The mean is the average value of the given data set. When the outlier is removed the mean and the median of the data set are changed.

<h3>What are mean, median, and mode?</h3>

The mean is the average value of the given data set.
The median is the middle value of a given data set when the data is arranged in increasing order.
The mode is the number that is repeated the most number of times in a given data set.

The data set can be arranged as 12, 19, 19, 20, 21, 22, 22, 23, 24, 26, 27, 28, 29, 30, 32, 35, 48. Now, The means, median and mode for the data set is,

Mean = (29+19+35+27+21+48+23+12+24+26+20+28+30+22+19+32+22) / 17

Mean = 25.7

Median(The middle value when the data is arranged in increasing order) = 24

Mode = 19,22

The outlier in the data set is 48, therefore, the mean median and mode now will be,

12, 19, 19, 20, 21, 22, 22, 23, 24, 26, 27, 28, 29, 30, 32, 35

Mean = 24.3125

Median = 23.5

Mode = 19, 22

Hence, when the outlier is removed the mean and the median of the data set are changed.

Which is an equation in point-slope form for the given point and slope?

Akimi4 [234]

Answer:

The answer to your question is the letter D. (step 2)

Step-by-step explanation:

Data

P (7, 4) slope = 6

Process

1.- Write the equation of the line

y - y1 = m(x - x1)

x1 = 7 y1 = 4

2.- Substitution

y - 4 = 6(x - 7)

- Simplification

y - 4 = 6x - 42

- Solve for y

y = 6x - 42 + 4

y = 6x - 38 This is the equation in the point-slope form

3.- According to the choices the answer is letter D.
