Answer: For you : 100+5x=200
For Josh : 50+10x=200
Step-by-step explanation:
Given : Cost of video game.= $200
Money you have = $100
Money you add each week = $5
Let x be the number of week, the money( in $) you have after x weeks = 100+5x
Josh has $50 in save $10 each week , then money( in $) Josh has after x weeks = 50+10x
Required equations :
For you : 100+5x=200
For Josh : 50+10x=200
Answer:
The probability of falling into a type I error, when testing a hypothesis test, consists of:
Probability of rejecting the null hypothesis when, in reality, this hypothesis is true.
Probability of rejecting the null hypothesis when, in reality, this hypothesis is true, is:
Probability of Affirm that Chemistry exam will NOT cover only chapters four and five, since the Chemistry exam will cover only chapters four and five.
That is, alpha is the probability that Carmin decides to study additional chapters, unnecessarily.
Step-by-step explanation:
Answer:
41 and 24
Step-by-step explanation:
x+y=65 -------(A)
x-y=17 -------- (B)
(A)+(B)
(x+y)+(x-y)=65+17
2x=82
x=41
(B)===>
41-y=17
y=41-17
y=24
Answer:
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
Step-by-step explanation:
i) f(x) = -(x+9)(x-21)
ii) therefore y = f(x) = -
+ 12x + 189 = - ( - 12x +36) + 36 + 189
iii) therefore y = f(x) = - 
+ 225
iv) when x = 6 then y = 255
Therefore the given equation is a parabolic equation with vertex at (6,255) and the axis of symmetry is given by x = 6.
