Answer:
9
Step-by-step explanation:
y=x
y=kx
substitute k for 0.75 and x for 12 in the above equation
y=0.75×12
y=9
Answer:
a= 2b-x
Step-by-step explanation:
You have to isolate the variable by dividing each side of the factors that does not contain the variable "a".
Hello!
Her first commision would have to be multiplied by 5% first, which would be 6,000 x .05
This would equal to $300.
The second part would be .075 x 6000.
This equals to $450
Then, .01 x 12,000
This equals to $120.
Add all commisions, 300+450+120
****$870 is the total commision she received. ****
I hope I did this right. It's my first time on brainly. Tell me if you got it. Sorry if I didn't help
We can solve this pretty easily using a proportion where x equals the number of cloudy days in the year:
2/5 = x/365
Now cross multiply:
730 = 5x
And finally divide both aides by five:
146 = x
So 146 days of the year were cloudy.
Hope I helped, and let me know if you have any questions!
Answer:
We cannot determine the appropriate hypotheses to test this study because we are only given the data for the sample size and the population mean. Meanwhile, we need to know the data of the sample mean, the standard deviation and the level of significance before we can state the appropriate hypotheses for this test.
Step-by-step explanation:
Given that:
sample size n = 300
population mean μ = 35
The null hypothesis and the alternative hypothesis can be computed as follows:
Null hypothesis
Alternative hypothesis
The degree of freedom df = n -1
df = 300 - 1
df = 299
