Answer:
9/2
Step-by-step explanation:
f(x)=5-1/2
plug in 4
f=9/2
9/2
Multiples of 5 are A{5,10}
multiples of 2 are B{2,4,6,8,10,12,14}
Multiples of 2 OR 5 are {2,4,5,6,8,10,12,14} for 8 possible outcomes.
Therefore the probability of spinning a multiple of 2 or 5
P(2x or 5x)=8/14 = 4/7
- Slope-Intercept Form: y = mx + b, with m = slope and b = y-intercept
- Slope Formula:
So firstly, to find the slope of this equation, plug the two points, (1,1) and (-3,2), into the slope formula and solve as such:
Next, plug either one of the points into the x and y coordinates to solve for b as such:
<u>Our final equation is 
, or the third option.</u>
Answer:
the kit costed $40 - $6 = $34 after the first general discount. Now the question is if the coupon relates to the original price or to the lowered price. We'll do both:
If it relates to the original price, we need to find how much is 25% of $40. We can do it in mind - it's $10. So with two discounts the price would be $40 - $6 - $10 = $24.
However, if it relates to the lowered price, we need to find how much is 25% from $34:
34 * 25% =
= 34 * 25/100 =
= 34 * 1/4 =
= 8.5 [dollars]
So the final price in such a situation would be $40 - $6 - $8.5 = $25.5
