Given:
The zeros of the polynomial are .
Degree = 4
Leading coefficient = 1
To find:
The polynomial.
Solution:
If c is a zero of a polynomial, then (x-c) must be a factor of the polynomial.
Here, -2,4,-5, 5, are zeros of the required polynomial, so (x+2), (x-4), (x+5), (x-5) are factors of required polynomial.
Using distributive property, we get
On combining like terms, we get
Here, the leading coefficient is 1. So, it is the required polynomial.
Therefore, the correct option is E.
a tennis ball has a diameter of about 2.5 inches
so volume of a tennis ball is: 4/3 x pi x r^3 = 8.2 cubic inches ( estimating you could say 8 cubic inches
1 cubic foot = 1728 cubic inches
so you could fit 1728/8 = 216 tennis balls in a cubic foot.( estimated)
you would then need to calculate the volume of the room
lets say a small room is 9 foo by 9 foot by 8 feet high
9 x 9 x 8 = 648 square feet
now multiply the 216 by the square feet of the room
216 * 648 = 139,968tennis balls
now because they are round, there will be empty space around them
so you could estimate about 139,000 tennis balls would fit I a 9 x 9 room that is 8 feet high.
You didn't give the dimensions of the room, but this gives you the idea of how to estimate
Answer:
Step-by-step explanation:
Given that a poll showed the approval rating to be 0.45 (45 %)
Second poll n =2500: sample p = 1185/2500 = 0.474
H0: p = 0.45
Ha: p not equals 0.45
(Two tailed test)
p difference = 0.024
z-statistic 0.179
Significance level P = 0.8577
95% CI of observed proportion 0.24% to 0.83%
Since p>0.05 we accept null hypothesis
The results of the second poll do not indicate that the proportion of voters who approve of the job the president is doing is significantly higher than the original level
Answer:
15
Step-by-step explanation:
To isolate the variable, subtract 95 on both sides.
110=m + 95
m=15
