UHM
Answer:
18.87%
Step-by-step explanation:
Let's say that adult that needs correction is A(83%) and adult that doesn't need correction is B(17%). There are two combinations of event that result at "at least 16 out of 17 adults chosen need correction" which is:
1. 17A
2. 16A + 1 B
The probability for 17A should be easy to determine, it is simply A^17.
You will need a pascal triangle for 16A + 1 B event combination, not only A^16*B^1. It's pretty easy to know the coefficient since its just 1 different case so it's 16+1= 17. The chance will be:
1A^17 + 17A^16*B^1=
0.04210 + 0.1466= 0.1887= 18.87%
If you use 5% as significant cutoff, then it's not significant because the probability of this occurring is not small.
Answer:
The y-intercept is at y = 10.
Step-by-step explanation:
It will be between y = 14 and y = 7 because the corresponding x values are -2 and 1.
An increase of 3 units of x gives a decrease of 6 units of y fro the above values.
Then an increase of 1 ( 1 to 2) in x gives decrease in y of 2 (8 to 6). The other values show the same pattern.
So very unit increase in x, the y values change by -2.
So from x = -2 to 0 is +2 units for x and this will be -4 units for y so the y-intercept ( when x = 0) will be at y = 14-4 = 10
y-intercept is (0,10).
The possible rectangle's length and width are A) 1 cm and 15 cm and C) 3 cm and 5 cm
<h3>How to determine the possible rectangle's length and width?</h3>
The given parameters are
Area = 15 square cm
The area is given as
Area = 15 square cm
The formula of area is
Area = Length x Width
Using the above formula, we have:
A) 1 cm and 15 cm ⇒ 15 square cm
B) 2 cm and 7 cm ⇒ 14 square cm
C) 3 cm and 5 cm ⇒ 15 square cm
D) 4 cm and 4 cm ⇒ 16 square cm
Hence, the possible rectangle's length and width are A) 1 cm and 15 cm and C) 3 cm and 5 cm
