Answer: x=-10, y=-5 or -2/1. And it's dilated by 2. & i believe the scale factor is 2.

Step-by-step explanation:

What i did was simply count from the radius (the tiny dot in the center) up, and i counted 3, and did the same w/ the A' so I got 6, why makes me assume the scale factor is 2. then i did rise/run and i went 10 left and 5 down. So that makes -10,-5.

Work out, giving your answer in its simplest form: 5/ 14 x 7/ 30

Elena L [17]

X in (-oo:+oo)

((5/14)*x^7)/30 = 0

1/84*x^7 = 0 // : 1/84

x^7 = 0

x = 0

x = 0

A group of 6 students was asked, "How many hours did you watch television last week?" Here are their responses: 19, 9, 18, 16, 1

Anton [14]

Answer:

Mean = 15.83 hours

Median = 17 hours

Step-by-step explanation:

The first step to follow when dealing with data distributions is to arrange the data in either an ascending or descending order.

Once this is done, we have the responses as

responses: 9. 14, 16, 18, 19, 19

The mean of the distribution can be obtained by dividing the total sum of the values, by the number of respondents.

this is $9 +14 + 19 + 18 + 16 + 14 + 19/ 6= 95/6 = 15.83$

The mean of the distribution is 15.83 hours

The median is obtained by picking out the middle number of the distribution. However, our distribution is even, and hence has two middle numbers. To solve this , we simply add the two numbers and divide by 2

= (16 + 18 )/2 = 34/2 = 17

PLS HELP! What is the frequency of the sinusoidal graph?

docker41 [41]

the frequency of the sinusoidal graph is 2 in 2 π interval

Step-by-step explanation:

The frequency of the graphs refers to the number of the cycles, the graph completes in a given fixed interval.

We already know the formula that

P= (1/ F)

Thus, F= (1/ P)

Where F= frequency and P= Period

Period is the horizontal length (x- axis component) of one complete cycle.

Thus, Observing the above graph

We find that the graph completes 1 cycle in π interval and 2 cycles in 2π interval

Thus, the frequency of the sinusoidal graph is 2 in 2 π interval
