Answer:
Option C.
Step-by-step explanation:
The general form of exponential growth function is
where, a is initial values and b is growth factor, b>1.
The given function are
In functions 1,2, and 4 the values of b are 0.07, 0.44 and 1/2 respectively. The values of b are less than 1. It means they represent exponential decay.
In function 3, the values of b is 6, which is greater than 1. It means it represent exponential growth.
Therefore, the correct option is C.
Answer:
The degrees of freedom are
And the p value for this case is:
The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.
Step-by-step explanation:
Information provided
represent the sample mean
represent the sample standard deviation
sample size
represent the value to verify
t would represent the statistic
represent the p value
System of hypothesis
We want to verify if the average amount of coffee per cup is different from 7 ounces, the system of hypothesis would be:
Null hypothesis:
Alternative hypothesis:
The statistic is given by:
(1)
Replacing the info given we got:
The degrees of freedom are
And the p value for this case is:
The p value is a higher value and using a significance levels of 5% or 10% we see that the p value is higher than the significance level and then we FAIL to reject the null hypothesis and we don't have enough evidence to conclude that the true mean is different from 7 ounces.
Answer:
$4
Step-by-step explanation:
5c + 4p=28 equation 1
2c + 2p=12 equation 2
-2(2c +2p)=-2(12) multiply equation 2 by -2 so you can solve by elimination.
-4c-4p=-24 equation 2 multiplied by -2
5c+4p=28. Equation 1
c=4 added above 2 equations
solve for plates:
2c + 2p=12
2(4)+ 2p=12
8+2p=12
2p=4
p=2
check answer:
5c+4p=28. Equation 1
5(4)+4(2)=28
20+8=28
28=28
Answer:
9 kg of tomatoes
Step-by-step explanation:
Cost of 40 kg of tomatoes = $200
Cost of 1 kg of tomatoes = 200/40 = $5
For $45, we get x kg of tomatoes,
kg $
1 5
x 45
=> 45*1/5 = x kg (by cross multiplication)
=> 45/5 = x kg
We get 9 kg of tomatoes for $45.
Hope you understood!
