Well 1 minutes is 60 secounds so yes it is it is 300 secounds
Okay, so the y-intercept is the "b" in this case and the m is your slope so, therefore, you have y=- 1/2x-5
6x+15y=-45
<span>6x+5y=-35
subtract second equation from the first
</span>6x+15y=-45
<span>6x+5y=-35
</span><u>- - +
</u> 10y = -10
⇒ y = (-10/10) = 1
put value of y in one of the equation,
6x+5y = -35
⇒ 6x + 5(-1) = -35
⇒ 6x - 5 =-35
⇒ 6x = -35 + 5 = 30
⇒ x = 30/6
⇒ x = 5
So x=5 and y=-1.
Answer:
And replacing the value obtained we got:
And if we solve for a we got
Step-by-step explanation:
Let X the random variable that represent the average home prices of a population, and for this case we know the distribution for X is given by:
Where and
For this part we want to find a value a, such that we satisfy this condition:
(a)
(b)
We want to find a value who accumulate 0.10 of the area on the left and 0.90 of the area on the right of the normal standard distributon and for this case it's z=-1.282
And using the distribution for the sample mean we can do this:
And replacing the value obtained we got:
And if we solve for a we got
Answer:
6 or 8
Step-by-step explanation:
For every cycle of picks Sweet T has she gets 2 orange and 5 green. 2+5=7. To find how many cycles there are divide 25/7= 3 Remainder:4. To mind how many orange then do 3 times 2(2 for each cycle)=6.
The reason I say 6 or <u><em>10</em></u> is that you could add 2 oranges from the remainder to the total # of oranges.
