Answer:

Step-by-step explanation:

(-1,1) and (0,-2) are points on the line

slope of line = (-2-1)/(0-(-1)) = -3

y-intercept = -2

y = -3x - 2

Answer:

y = 3x + 3

Step-by-step explanation:

when you check, only that equation delivers the correct x and y pairs.

x = 0, => y = 3×0 + 3 = 3

x = 1, y = 3×1 + 3 = 3+3 = 6

x = 2, y = 3×2 + 3 = 6 + 3 = 9

x = 3, y = 3×3 + 3 = 9 + 3 = 12

it all fits.

Which is the correct classification for the triangle?

kondaur [170]

Acute means that has 3 angles less than 90 degrees

obtuse means at lesat 1 angle is more than 90 degrees

right triangle means 1 angle=90 degrees

s we solve for thierd angle
all angles add to 180 so
35+45+x=180
80+x=180
subtract 80
x=100
100>90

obtuse angle is answer

Six different second-year medical students at Bellevue Hospital measured the blood pressure of the same person. The systolic re

Answer:

$Range = 149-131=18$

$s^2 =\frac{(131-139.5)^2 +(137-139.5)^2 +(138-139.5)^2 +(141-139.5)^2 +(141-139.5)^2 +(149-139.5)^2}{6-1}=35.1$ $s =\sqrt{35.1}=5.9$

B. Ideally, the standard deviation would be zero because all the measurements should be the same.

Step-by-step explanation:

For this case we have the following data:

131 137 138 141 141 149

For this case the range is defined as $Range = Max-Min$

And for our case we have $Range = 149-131=18$

First we need to calculate the average given by this formula:

$\bar X = \frac{\sum_{i=1}^n X_i}{n}=\frac{837}{6}=139.5$

We can calculate the sample variance with the following formula:

$s^2 = \frac{\sum_{i=1}^n (X_i -\bar x)^2}{n-1}$

And if we replace we got:

$s^2 =\frac{(131-139.5)^2 +(137-139.5)^2 +(138-139.5)^2 +(141-139.5)^2 +(141-139.5)^2 +(149-139.5)^2}{6-1}=35.1$

And the standard deviation is just the square root of the variance so then we got:

$s =\sqrt{35.1}=5.9$

If the subject's blood pressure remains constant and the medical students correctly apply the same measurement technique, what should be the value of the standard deviation?

For this case the variance and deviation should be 0 since we not evidence change then we not have variation. And for this case the best answer is:

B. Ideally, the standard deviation would be zero because all the measurements should be the same.
