Answer:
62%
Step-by-step explanation:
Given the information :
224 visitors purchased no costume.
103 visitors purchased exactly one costume.
32 visitors purchased more than one costume.
Based on these results, express the probability that the next person will purchase no costume as a percent to the nearest whole number.
Probability that next person will purchase no custome:
Probability = no of successes / total number of trials
Total number of trials :
(purchase no custome + purchase exactly one + purchase more than one)
= (224 + 103 + 32) = 359
Hence, Probability that next person will purchase no custome:
= 224 / 359
As a percentage :
(224 / 359) * 100%
= 0.6239554 * 100%
= 62.39 %
= 62% ( nearest whole percent)
a) Reduction because the second figure is smaller than the original one.
b) The scale factor is 2 units.
Answer:
+/- 1, 
....
Step-by-step explanation:
The Rational root theorem states that If f(x) is a Polynomial with integer coefficients and if there exist a rational root of the form p/q then p is the factor of the constant term of the function and q is the factor of the leading coefficient of the function
Given: f(x)= 9x^4-2x^2-3x+4
Factors of q (leading coefficient) are: +/-9, +/-3, +/-1
Factors of p (constant term) are: +/-4 , +/-2, +/- 1
According to the theorem we write the roots in p/q form:
Therefore,
p/q =+/- 1, ....
Answer:5*11
Step-by-step explanation:
As we know the formula to calculate the line of equation is y - y1 = m (x - x1)
Where m is the slope. y1 is the first y co ordinate. x1 is the first x co ordinate.
Now we do know that the slope of parallel line is the same as the slope of the original line.
So parallel line slope is 3 so slope for our line is 3. Hence equation is y - 7 = 3 (x - 2) which becomes y = 3x + 1.
