Amount of money saved by Jordon for the video game = (4/5) * 80
= 4 * 16 dollars
= 64 dollars
So
The amount of money that
Jordan needs to earn more for buying the video game = (80 - 64) dollars
= 16 dollars
Amount earned by Jordan per hour working at a pizza shop = $7.75
Let us assume the number of hours Jordan needs to work to save the rest of the money for the video game = x
Then
7.75x = 16
x = 16/7.75
= 2.06 hours
So it can be said that Jordan has to work 3 hours to save the rest of the money for the video game. If Jordan works 2 hours then he will be short of the required amount. If Jordan works for 3 hours he will have some excess amount in his hand after saving for the video game.
Answer: The observed ratio is different from the expected ratio.
Step-by-step explanation:
Since we have given that
Expected ratio :
Ratio of blue flowered plants to white flowered plant = 3:1
Observed results:
Number of blue flowered plants = 35
Number of white flowered plants = 14
So, Ratio of blue flowered plants : white flowered plants
So, 5:2 ≠ 3:1
Hence, the observed ratio is different from the expected ratio.
Answer:
Alright solve for x by multiplying both sides of the equation then isolating the variable
x = - 10 Hope this helps :)

Answer: 120
<u>Step-by-step explanation:</u>
Permutation means that order matters.
P5
From Z tables and at P5 = 5% = 0.05, Z = -1.645
Therefore,
True value = mean +Z*SD = 24.1+(-1.645*2.1) = 20.6455 Chips per cookie
P95
From Z table and at P95=95%=0.95, Z= 1.645
Therefore,
True value = 24.1 +(1.645*2.1) = 27.5545 Chips per cookie
These values shows the percentages of amount of chips in the cookies. Thus, the more the percentage considered, the more the amount of chips in the cookies. This can be used to control the number of chips in cookies during production.
