A python curls up to touch the tip of its own tail with its nose, forming the shape of a circle. The python is 2.6π meters long.

What is the radius "r" of the circle that the python forms?

The python is 2.6pi meters long. This is the circumference because it's the distance around the circle. So, C = 2.6pi

We will plug this into the formula below and isolate r

C = 2*pi*r
2.6pi = 2*pi*r
2.6 = 2*r .... divide both sides by pi
2.6/2 = 2r/2
1.3 = r
r = 1.3

Since r = 1.3, this means that the radius is 1.3 meters.

A scientist wants to find the average weight of fish living in a large pond. So she will use the weights of 25 fish from the pon
lidiya [134]

Answer:

Use interval estimation to compute the average weight of fish living in a large pond.

Step-by-step explanation:

In statistic, point estimation comprises of the use of sample data to estimate a distinct data value (known as a point estimate) which is to function as a "best guess" or "best estimate" of an unidentified population parameter.  

The point estimate of the population mean (<em>µ</em>) is the sample mean (\bar x).

Now according to the law of large numbers, in probability concept, states that as we increase the sample size, the mean of the sample (\bar x) approaches the whole population mean (µ).

That is, \bar x →  <em>µ</em> as <em>n</em> → ∞.

The scientist uses the weights of 25 fish from the pond to find the average weight.

The sample is large, but not large enough.

So, use interval estimation to compute the average weight of fish living in a large pond.

The interval estimation is the best way to estimate the true value of a parameter. This is because the interval of values computed for the parameter has certain probability of containing the true parameter value.

The (1 - <em>α</em>)% confidence interval for population mean is an interval estimate.

Name the coordinates of the final image of the figure after the given sequence of
slega [8]

9514 1404 393

Answer:

  • S''(5, -3)
  • T''(1, 0)
  • U''(4, 1)
  • V''(4, 0)

Step-by-step explanation:

The end result after the final transformation is ...

  (x, y) ⇒ (-x, y)

so, each x-coordinate is negated. The transformed coordinates are ...

  S(-5, -3) ⇒ S''(5, -3)

  T(-1, 0) ⇒ T''(1, 0)

  U(-4, 1) ⇒ U''(4, 1)

  V(-4, 0) ⇒ V''(4, 0)

What is the equation of the line that passes through the point (3, -1) and is perpendicular to the equation y = -3x + 2? A. y=-3
LenKa [72]

Answer:

A) y = –3x+8

Step-by-step explanation:

first off, a negative equation means the graph is downward sloping from left to right –> \. So with this in mind you can immediately eliminate C and D because they are upward sloping graphs. B also doesn't work because it doesn't go through (3,–1). This leaves A as the right answer

the constant number is the number on the y-axis. So, for –3x+2, +2 is the y-coordinate on the y-axis. the slope is -3x meaning down 3, right 1. –3x+8 is the only answer that is perpendicular.

State whether the relationship between x and y in y=4x-5 is proportional or not
mart [117]
The answer is "No they are not proportional" since the line y = 4x-5 doesn't go through the origin. Put another way, the equation is not in the form y = k*x for some fixed value k.
