According to the National Weather Service, the average monthly high temperature in the Dallas/Fort Worth, Texas area from the years of 2006-2008 is given by the following table: Month Average Maximum Monthly Temperature Jan 48.1 Feb 50.9 Mar 62.4 Apr 67.0 May 76.5 Jun 83.9 Jul 86.8 Aug 88.1 Sep 79.2 Oct 69.9 Nov 59.5 Dec 49.6 Plot the data on a scatter plot. Produce a sine regression model for the data. Round the values for a, b, c, and d to the nearest 0.001. Using the sine regression model predict what the temperature would be given y(30). a. 58.4 degrees b. 62.3 degrees c. 76.8 degrees d. 86.0 degrees Not D

Step-by-step explanation:

It’s D

x = -2

y = 848

plug in the numbers

b. an equilateral triangle inscribed in a circle

step-by-step explanation:

we are given the figure of two circles having a triangle inside.

now, we know that,

"when a figure is lying inside an another figure, then the outside figure is known as circumscribed figure and the figure lying inside is referred to as the inscribed figure".

as we see that, the circles are containing the triangle completely.

thus, the circles are the circumscribed figures and the triangle is the inscribed figure.

hence, we get, 'an equilateral triangle is inscribed in a circle'.
