Collinear is when two points are on the same plane. For example: in this picture A B C and D are collinear. Two points can still be collinear if they don’t have a line in between them too, just as long as you can draw a straight line between them they are collinear.

Answer:

y=2x+6

Step-by-step explanation:

slope intercept formula → y=mx+b

$\frac{6-2}{0-(-2)} =\frac{4}{2} =2\\$

so 2 is your slope and the point (0,6) crosses the y-intercept at 6 since x = 0

plugin 2 for m (or the slope) and 6 for b (y-intercept)

your answer → y=2x+6

20 points if you help me solved this problem plz it’s urgent someone plz help me I need help! Will mark you as brainiest!

deff fn [24]

Answer: see below

Step-by-step explanation:

C(x) = 39 when 0 < x ≤ 1.0

C(x) = 63 when 1.0 < x ≤ 2.0

C(x) = 87 when 2.0 < x ≤ 3.0

C(x) = 111 when 3.0 < x ≤ 4.0

C(x) = 135 when 4.0 < x ≤ 5.0

C(x) = 159 when 5.0 < x ≤ 6.0

Based on the information I provided above, the answers are:

a) x= 0.6, C(x) = 1.0

x = 1.0, C(x) = 39

x = 1.1, C(x) = 63

x = 2.5, C(x) = 87

x = 3.0, C(x) = 87

x = 4.8, C(x) = 135

x = 5.0, C(x) = 135

x = 5.3, C(x) = 159

b) If C(x) = 87, then 2.0 < x ≤ 3.0

c) Domain (all possible x-values): 0 < x ≤ 6.0

d) Range (all possible y-values): {39, 63, 87, 111, 135, 159}

Suppose you are a climatologist. You conduct a hypothesis test to determine whether the global mean temperature in the current y

Answer:

The term "El Nino" refers to the warming of the central and eastern tropical Pacific waters that occurs every 3 to 7 years and typically lasts from 9 to 12 months. The 1997-1998 El Nino, the strongest ever recorded, affected climate patterns worldwide. Its effect, combined with an increasing trend in annual global temperatures, made 1998 the warmest year in the 20th century. Suppose you are a climatologist. You conduct a hypothesis test to determine whether the global mean temperature in the current year is different from the global mean temperature in 1998. Assume that the global mean temperature in 1998 is 14.3 degrees Celsius. You obtain a preliminary sample of temperatures from recording stations worldwide, which yields a sample mean of x bar = 15.1 degrees Celsius. Let mu denote the global mean temperature in the current year. Formulate your null and alternative hypotheses by selecting the appropriate values in the blue drop-down menus that follow.
