Because the time moved up by 15 minutes, we would already know that it would be (blank) megabytes per 15 minutes
75 megabytes - 15 megabytes = 60
this would mean 60 megabytes are downloaded per 15 minutes
simplified by 15, our answer would be 4 megabytes downloaded per minute
both of the answers above would be acceptable :)
Answer:
7/40
Step-by-step explanation:
There are 3 girls+9 boys = 12 students in the 7th grade
P (girl in 7th grade) = girls/ total
= 3/12 = 1/4
There are 7 girls+3 boys = 10 students in the 8th grade
P (girl in 8th grade) = girls/ total
= 7/10
P(7th grade girl, 8th grade girl) = 1/4 * 7/10 = 7/40
Keith's bank account starts with $250 and he adds $150 to it every month. If <em>m</em> is the number of months that have passed, then the amount of money (in dollars) in his account is given by
250 + 150<em>m</em>
<em />
Victoria's account starts with $2000 and she removes half of it each month. So after <em>m</em> months, her account has a value of
2000/2^<em>m</em>
<em />
If you were to plot these amounts, then
(a) Keith's account's value is indeed linear - TRUE
(b) Keith is constantly adding money to his account, so its value is increasing - FALSE
(c) Victoria's account's value involves an exponential expression - TRUE
(d) Victoria is removing money, so the value is decreasing - TRUE
Your answers are correct except for (c).
36 and 100 are both square numbers.
However, only 100 is within the given range.
1. x=-2
2. y=-4x+1
3. not sure
