Answer:y=4x -7
Step-by-step explanation:
The slope intercept form is: y= mx + b
Y+3 = 4(x-1) step one distribute 4
Y+3= 4x - 4 step two subtract 3 from both sides
Y=4x -7
Answer: 0.81859
Step-by-step explanation:
Using the formula ;
Z = 
where u = mean
Therefore the probability that a student will finish the test between 40 and 70 will be :
P ( 40≤X≤70 ) = P(X≤70) - P(X≤40)
P ( 60-40/10) , P( 60 - 70 / 10)
= 2 , -1
= P (Z ≤ 2) - P( Z ≤ -1 )
From normal table , we have
0.97725 - 0.15866
Therefore the probability that a student will finish the test between 40 and 70 minutes = 0.81859
The answer is C. The rate the population increases. The 960 in the equation represents the population at a certain number of weeks which is x. The starting population describes the quantity 15. The number of weeks that have passed is described as the 6 weeks.
The equation would be described as: f(x) =15*(2^x) and f(x) =960
18. 2(x + 26) = 264
x = $106
20. (9/5)C + 32 = F
(9/5)(-35) + 32 = F
-63 + 32 = -31 degrees F
22. 73 = 2x + 11, x = the original number of customers
x = 31 original customers
24. 8x + 19 = 115
x = 12 days
