Answer:
Amounts in the intervall
Step-by-step explanation:
We will take the variables c and s, where
c = amount to spend that month
s = savings of the month.
Since each month we save at least 100, we know that
Moreover, we earn $250 per month and we spend $20 in a kayaking club, which tells us that
and so
By multiplying by -1, the first inequality also tells us that
Consequently by adding 230 to the inequality, we get that
Hi there
The formula is
I=prt
P principle 14300
R interest rate 7+1/2=7.5%
T time 4 years
I=14,300×0.075×4
I=4,290
Hope it helps
Add all the chips to find the total amount.
7 + 9 + 3 + 6 = 25 chips
Since there are 6 blue chips (6/25), that's the probability of just getting once.
When you pick a blue chip and it doesn't get replaced, then that means there is one fewer blue chip and one fewer from the total amount.
5/24
Multiply both probabilities.
6/25 * 5/24 = 30/600
Simplify.
30/600 → 1/20
Therefore, the answer is B
Best of Luck!
Answer:
<h2>y + 2 = (-5/4)x - 11.25</h2>
Step-by-step explanation:
If the relationship f is linear then its graph is a line D of equation y = ax+b
(-9 ,-2)∈D ⇔ -2 = -9a + b (1)
(-5 , -7)∈D ⇔ -7 = -5a + b (2)
(2)-(1)⇒ -5 = 4a ⇒ a = -5/4
-2 = -9a + b ⇒ -2 = -9(-5/4) + b ⇒ 2 +45/4 = -b ⇒ b = -13.25
then
D : y = (-5/4)x - 13.25 ⇒ y + 2 = (-5/4)x - 11.25
since (-1,-12) and (3,-17) are points of D (easy to check)
then it’s a linear relationship
