Step-by-step explanation:

2x-y=6 --------(1)

x+y=6 -------(2)

_____ Adding (1) and (2)

3x = 12

An engineering school reports that 59% of its students are male (M), 39% of its students are between the ages of 18 and 20 (A),
KIM [24]

Answer:

.26

Step-by-step explanation:

.59 = M

.39 = A

.24= M∩A

M'∩A'= ?

M'∩A'= (M∪A)' (we call this demorgan's law)

MUA= M+A-M∩A

.59+.39-.24= .74

1-.74= .26

The heights (in cm) and arm spans (in cm) of 31 students were measured. The association between (height) and (arm span) is shown
sergeinik [125]

Answer: Mike's arm span is 7.165 cm longer than the George's one.

Step-by-step explanation:

We have that the association between height and arm span is modeled by the equation

y = 4.5 + 0.977*x

where y is height and x is arm span.

Mike is 172 cm tall, so his arm span is:

172cm = 4.5 + 0.977*x

x = (172 - 4.5)/0.977 = 171.443 cm

and George is 165 cm tall, so his arm span is:

x = (165 - 4.5)/0.977 = 164.278 cm

Then the difference between their arm span is:

171.443cm - 164.278cm = 7.165 cm

So Mike's arm span is 7.165 cm longer than the George's one.

26) Write the equation of the circle with center (0, 0) and (3, 6) a point on the circle. A) x2 + y2 = 9 B) x2 + y2 = 30 C) x2 +
alexdok [17]

Answer:C) x2 + y2 =45

Step-by-step explanation:

The equation of a circle in standard form is (x-h)2+(y-k)2=r2.

Since you know the center is (0,0), you can sub this is value in for h and k, then use the point (3,6) to sub in for x and y and you will find r2 =45. Hope that helps :)

Give the equation of the circle whose center is (5 -3) and goes through (2 5)
Alekssandra [29.7K]

Answer:

Step-by-step explanation:

The standard form for the equation of a circle is

(x-h)^2+(y-k)^2=r^2

From the info given, we have the center, (h, k) as (5, -3) and the x and y coordinates of (2, 5).  We will use these to solve for r-squared, then plug back in what we need to write the equation.

(2-5)^2+(5-(-3))^2=r^2 which simplifies to

(-3)^2+(8)^2=r^2 and

9+64=r^2 so

r^2=73

Filling in the equation:

(x-5)^2+(y+3)^2=73
