So this is an equation.
The starting value is the given value 400.
She gave g packs to the orphanage, so she now has 400-g packages.
Then she divides that by 4 and gives to 4 different charities.
The answer is (400-g)÷4
Hope this helps!
Answer:
Fail to reject H0 in all three cases
Step-by-step explanation:
Given that a certain pen has been designed so that true average writing lifetime under controlled conditions (involving the use of a writing machine) is at least 10 hr.
![H_0: \bar x=10\\H_a \bar x >10](https://tex.z-dn.net/?f=H_0%3A%20%5Cbar%20x%3D10%5C%5CH_a%20%5Cbar%20x%20%3E10)
(Right tailed test at 1% sign level)
n = 19
a) t =-2.5 , df = 18
p = 0.01154
p >1% hence Fail to reject H0
b) t = −1.83
p = 0.041931
p >1% Fail to reject H0
c) t = 0.57
p = 0.287>1% Fail to reject H0
Answer:
A) y=23-5x
b) y= -14+2x
Step-by-step explanation:
a) 5x+y=23
-5x -5x
___________
y=23-5x
b)
2x-y=14
-2x -2x
_________
-y=14-2x
__ ___
-1 -1
y=-14+2x
Answer:
miles
Step-by-step explanation:
If Leon can drive 100 miles in 2 hours,
He can drive
miles in 1 hour.
Since there are 60 minutes in 1 hour, <em>what fraction of an hour is 40 minutes?</em>
<em>
of an hour</em>
So in 40 minutes he can drive
miles
In 2 hours and 40 minutes, he can therefore drive:
miles
Answer:
y =1/3x+20
Step-by-step explanation:
He starts 20 minutes late so we need to add 20 minutes to the time
He travels 3 times faster so he takes 1/3 of the normal time x
y =1/3x+20
