Answer:
10/3
hope this helps :)
The slope of line PQ calculated using the the formula (y₂-y₁)/(x₂-x₁) comes out to be -3 as given in the question. However, the complete information for line S is not provided, so its slope cannot be calculated.
The question is related to the types of lines formed by the given points in a Cartesian plane. Here, m(PQ) and m(S) represent the slopes of the lines formed by points P and Q, and line S respectively.
We calculate the gradient or slope of a line using the formula m = (y₂-y₁)/(x₂-x₁) where (x₁, y₁) and (x₂, y₂) are the coordinates of two distinct points on the line.
So, for line PQ the slope m(PQ) = (-1-14)/(2-(-3)) = -15/5 = -3. This matches the value given for m(PQ) in the question, thus establishing that PQ is a line with slope -3 in the Cartesian plane.
However, you haven't provided the complete information about the line S (only one coordinate is given). So, we cannot compute its slope. Please check the information given.

Step-by-step explanation:
Answer: 105.9 lbs and 309.3 lbs
Step-by-step explanation:
By Chebyshev's Theorem, the proportion of patients with weights within 4.5 standard deviations of the mean is at least 95%. Therefore k=4.5.
The weight that is 4.5 standard deviations less than the mean is 207.6−4.5(22.6)=105.9 pounds.
The weight that is 4.5 standard deviations greater than the mean is 207.6+4.5(22.6)=309.3 pounds.
So at least 95% of the patients have weights between 105.9 and 309.3 pounds.
Answer: 16^2 + 12^2
Step-by-step explanation:
20^2 = 400
16 x 16 = 256
12 x 12 = 144
256 + 144 = 400
Answer:
148 cm^2.
Step-by-step explanation:
It has 2 surfaces of area 5*6, 2 of 5*4 and 2 of 4*6.
= 2*30 + 2*20 + 2*24
= 60 + 40 + 48
= 148 cm^2.
