Answer:
r = 7.48
Step-by-step explanation:
47/2 = 23.5
23.5/ 7.48
r= 7.48
1.) The slope equals -5/4 because if we change the 4x+5y=-2 to a slope-intercept form then we can easily see the m (slope) and from that you switch the sign of the number and switch the numbers (ex. -1/2 = 2, 3 = -1/3). To get to the slope-intercept, you subtract 4x from both sides to get 5y=4x-2, then divide both sides by the 5 next to y to get y=4/5x-2/5.
2.) The equation would be y=1/3x+5 because if make the equation into a slope-intercept form by adding the x to both sides to get 3y=x+6 then divide both sides by 3 for y=1/3+2, then we can see the slope is 1/3 and since parallel lines have the same slope, you know the new line's slope is 1/3. Now if we put the slope into a new equation you'll get y=1/3x+b, so you then substitute the point's x and y in the equation for 5=1/3(3)+b, and then solve for b which is 5. Putting the y-intercept (b) and the slope into an equation, you get y=1/3x+5.
Answer:
B
Step-by-step explanation:
A geometric series will only converge if the common ratio r meets the requirement
- 1 < r < 1
The n th term of a geometric sequence is
= a
where a is the first term and r the common ratio
All terms inside the summation are of this form
The only one with - 1 < r < 1 is B where r = 
= 0.75
Answer:
last two numbers are 10,so their mean is 10
adding all means give us the mean of total data
