Answer:
C. The minimum of the function f(x) is 8.
Step-by-step explanation:
The curve opens downward so 8 is a maximum.
The figure consists of a rectangle and a circle.
first lets find the sides of the triangle
sides of the triangle are 4+4=8 and 3+1=4
therefore area of the rectangle is 8*4=32
now area of semicircle =πr^2/2 = π2^2/2=2π=6.3
we have to add the area of rectangle with the area of semicircle
this is because it the given figure no part of area of circle and rectangle are in common.
therefore total area of given figure = 32+6.3=38.3
%33.33
or
2/6
Because there are 6 sides on a die, and you are given 2 possible sides to roll on. This leaves you with 2/6, which translated to a fraction is %33.33
Answer:
Step-by-step explanation:
The null hypothesis is the hypothesis that is assumed to be true. It is an expression that is the opposite of what the researcher predicts.
The alternative hypothesis is what the researcher expects or predicts. It is the statement that is believed to be true if the null hypothesis is rejected.
From the given situation,
news article says that high school students are currently spending an average of 15 hours per week doing homework online. This is the null hypothesis.
H0: µ = 15 hours
You don't think this is an accurate estimate, although you're not sure whether the real value is higher or lower. This is the alternative hypothesis.
Ha : µ ≠ 15 hours
