70% of days in june were sunny how many days were sunny
goblinko [34]

There are 30 days in June. So 30 days represent 100% of the days:

30 = 100%    &   x = 70%  

so 100x= 2100

x= 21  Days

I hope this helps you! =^-^=

Find the missing lengths. Leave your answer in simplest radical form
KonstantinChe [14]
The right triangle has one angle = 60° and the second, 30°, then it is also a semi equilateral one & the side (y) opposed to the angle of 30° is equal to half of the hypotenuse (x).

Calculate x by Pythagoras:

x² = (5√3)² + y², but y = x/2==> y² =(x/2)² =x²/4

x² = 75 + x²/4 ==> 4x² = 300 + x²==> 3x²=300, x² =100 and x=10 and y =5

A company performs linear regressions to compare data sets of two similar products. If the residuals for brand A form an increas
Radda [10]
I think the correct answer would be B. If the residuals for brand A form an increasing curve, and the residuals for brand B form a U-shaped pattern, then neither of the data is likely to be linear. In order to be linear, the residuals of both data set should be, more or less, linear or approaching linearity in nature. Therefore, the linear regression that was done would not give good results since it is only applicable to linear data sets. Also, you can say that the relation of the data sets of the products are not linear. It would be best to do a curve fitting for both sets by using different functions like parabolic functions.
