According to a recent poll, 27% of adults in a certain area have high levels of cholesterol. they report that such elevated levels "could be financially devastating to the regions healthcare system" and are a major concern to health insurance providers. according to recent studies, cholesterol levels in healthy adults from the area average about 210 mg/dl, with a standard deviation of about 20 mg/dl, and are roughly normally distributed. assume that the standard deviation of the recent studies is accurate enough to be used as the population standard deviation. if the cholesterol levels of a sample of 45 healthy adults from the region is taken, answer parts a through d.

(a) what shape will the sampling distribution of the mean have?
(b) what is the mean of the sampling distribution?
(c) what is the standard deviation?
(d) if the sampling size were increased to 100, how would your answers to parts (a) - (c) change?

Answer: question no. 1 -a. yes, the sides are in the ratio 2 : 5.question no. 2 -b. 59°question no. 3 -c. angles x and y are remote interior angles.question no. 4 -d. 90°, 45° and 45°question no. 5 -b. mn and qrstep-by-step explanation: question no. 1 -rs : xu = 3 : 7.5 = 2 : 5rt : x? = 6.4 : 16 = 2 : 5st : u? = 6 : 15 = 2 : 5as the ratios of all sides are equivalent, the triangles must be congruent and the sides must be proportional.therefore, the answer is: a. yes, the sides are in the ratio 2 : 5.question no. 2 -in the second diagram, angle b is the only letter not shown. therefore, the number must be equivalent to angle b.if we substitute the value of angle b as being 22° in the first diagram, we can now use the angle sum of a triangle to obtain the value of angle a.angle sum of a triangle = 180°therefore: let angle a = aa + 99 + 22 = 180a = 180 - 99 - 22a = 59°therefore, the answer is: b. 59°question no. 3 -angles x and y don't share the vertex of the triangle with the exterior angle w. remote interior angles don't share a vertex of a triangle with an exterior angle. this means that angles x and y are remote interior angles.therefore, the answer is: c. angles x and y are remote interior angles.question no. 4 -the sum of all interior angles of a triangle must be equivalent to 180°.90°, 45° and 45° are the only set of angle measures that are equivalent to 180°.therefore, the answer is: d. 90°, 45° and 45°question no. 5 -the only pair of sides stated in the options which are corresponding are mn and qr.therefore, the answer is: b. mn and qr.

Igot you blocked a lot text me and back in you bye bye baby man

Hey mate where is the graph
