Answer:

Step-by-step explanation:

You can see that it "rises" 700 and "runs" 100, that means that there is a slope of 700/100. If you simplify that, it turn out to be a slope of 7. Meaning that each ticket costs $7. Hope this helps, let me know if you need a better explanation!

Lyme disease is an inflammatory disease that results in a skin rash and flulike symptoms. It is transmitted through the bite of

neonofarm [45]

Answer:

Step-by-step explanation:

Let cases of Lyme disease = x

x = 2, 1, 3, 4, 5, 1, 2, 1, 6, 5, 4, 1

$\sum x = 35$

$\sum x^2 = 139$

y = 0, 1, 2, 1, 3, 5, 2, 3, 3, 3, 1, 0

$\sum y = 24$

$\sum y^2 = 72$

$\sum xy = 55$

$S_{xx} = \sum x^2 - (\sum x)^2/n\\S_{xx} = 139 - 35^2/12\\S_{xx} = 36.92\\S_{yy} = \sum y^2 - (\sum y)^2/n\\S_{yy} = 72 - 24^2/12\\S_{yy} = 24$

$S_{xy} = \sum xy - ( \sum x \sum y)/n\\S_{xy} = 55 - (35*24)/12\\S_{xy} = -15$

b) Linear correlation between Lyme disease and drowning deaths.

$r = \frac{S_{xy}}{\sqrt{S_{xx}S_{yy}} }$

r = -15/ √(24*36.92)

r = -0.504

I need help, it’s a true or false question

marusya05 [52]

Answer:

The answer to this is False, False, True.

Step-by-step explanation:

A is false because WAU is an obstute angle, which can't be 55 degree.

B is flase because YAU is actually the angle that is 55 degree, not 35 degree.

C is true because WAX is congruent to YAU and it is 55 degree.

What would you do to find the arc length around 5/8 of a circle?

Andrew [12]

Answer:

5/8 * 2 * pi *r

Step-by-step explanation:

First find the circumference of the circle

C = 2 * pi *r

Then multiply it by the fraction of the circle ( arc length) you wish to find

5/8 * 2 * pi *r

Solve the math problem

olga55 [171]

Answer:

Step-by-step explanation:

DE = 50 BE = 5 BD = 10 (the slope) We draw a triangle DEB and an prove through vectors DE EB BD = 50 - 5 + 10 Perimeter length of DEB = 55 where the slope = 10 the height DB rate = 50/5 = 10/1 = 10 and therefore proves the constant linear is y = 10x where x = 1 The answer therefore is 10 or could stay limited to 50 as proved (50/5) but linear starting fro point of origin start at 0 and stay true to y/ x relationship = y/1 = 10/1
