Answer:
x<-2
Step-by-step explanation:
That is the answer derived from the given graph, where you can see that there is no inclusion of the number -2,
Answer:
She needs to sell for 64 more hours
Step-by-step explanation:
4f-5=7h+g
add 5
4f= 7h + g + 5
divide by 4 to get f by its self
f = 1/4g + 7/4h + 5/4
Answer: 5.37
Step-by-step explanation:
Let x = ACT scores.
Given: ACT scores have a mean of 20.8 and 9 percent of the scores are above 28. The scores have a distribution that is approximately normal.
i.e. P(X>28)=0.09 (i)
Now,
(ii)
One -tailed z value for p-value of 0.09 =1.3408 [By z-table]
From (i) and (ii)
![\dfrac{7.2}{\sigma}=1.3408\\\\\Rightarrow\ \sigma=\dfrac{7.2}{1.3408}\\\\\Rightarrow\ \sigma=5.37](https://tex.z-dn.net/?f=%5Cdfrac%7B7.2%7D%7B%5Csigma%7D%3D1.3408%5C%5C%5C%5C%5CRightarrow%5C%20%5Csigma%3D%5Cdfrac%7B7.2%7D%7B1.3408%7D%5C%5C%5C%5C%5CRightarrow%5C%20%5Csigma%3D5.37)
Hence, the standard deviation = 5.37
Answer: k = 76 degrees
Step-by-step explanation:
A linear pair of angles are always supplementary. (They sum to 180)
If the pair of angles are k and 104, they have to add up to equal 180.
180-104= 76
K has to equal 76 degrees
