The answer is A.
1/2*12*25
6*25
150 square inches
For this case, the first thing you should do is take into account properties of exponents.
We have then that we can rewrite the expression as follows:
^ 3√258 * (x ^ 10) * (y ^ 7)
^ 3√258 * ((x ^ 9) * (x)) * ((y ^ 6) * (y))
(x ^ 3) * (y ^ 2) (^ 3√258 * (x) * (y))
Answer:
The equivalent expression is:
(x ^ 3) * (y ^ 2) (^ 3√258 * (x) * (y))

Answer:
Yes based on the result 0.4841 the internet users watch less TV because the mean would be placed at 0.5 and it is less than 0.5
Step-by-step explanation:
a)The variable "weekly time spent watching television" is normally distributed and is skewed right.
b) Mean = x` 2.35 hours
Standard deviation = s/√n = 1.93/√40=1.93/6.3245553= 0.3051598
c) P(2<X<3) = P (2-2.35/ 0.3051598< Z< 3 -2.35/ 0.3051598)
= P ( -1.14694 < Z <2.13003)
= 0.3729 + 0.4830
=0.8559
So the probability is 0.8559
(0.8559 we check the value of 2.13 from the normal distribution tables and add with the value of 1.14 to get the in between value -1.14694 < Z <2.13003)
d) Here n = 35 , s= 1.93 , mean = 2.35 and x= 1.89
So Putting the values
P (X ≤ 1.89) = P (Z ≤ 1.89- 2.35/ 1.93 / √35)
= P ( Z ≤ -0.238341/ 5.9160797)
= P ( Z ≤ -0.04028)
= 0.5 - 0.0159
= 0.4841
Similarly again subtracting from 0.5 the value from normal distribution table to get less than or equal to value.
Yes based on the result 0.4841 the internet users watch less TV because the mean would be placed at 0.5 and it is less than 0.5
