Answer:
P(X = 2) = 0.27894
Step-by-step explanation:
Given:
- The probability that no vision correction is required p = 0.23
- No. adults are randomly selected n = 6
Find:
- P ( Exactly 2 dont require vision correction)
Solution:
- We will declare a random variable X is the umber of adults out of 6 that do not require vision correction. X follows a Binomial distribution:
X~ B ( 6 , 0.23 )
- The probability required is P ( X = 2 )
- Using the pmf of binomial distribution we have:
P(X = 2) = 6C2 * (0.23)^2 * (0.77)^4
P(X = 2) = 15 * 0.0529 * 0.35153041
P(X = 2) = 0.27894

Answer: g(x) has the smallest possible y-value of -3
<u>Step-by-step explanation:</u>
f(x) = 3ˣ - 3 <em>This is an exponential graph shifted down three units. So, it has an asymptote at y = -3, which means it approaches -3 but does not touch it.</em>
Range: y > 3 (-3, ∞)
g(x) = 7x² - 3
⇒ g(x) = 7(x - 0)² - 3 <em>This is a parabola with vertex at (0, -3) </em>
Range: y ≥ 3 [-3, ∞)
The expression of the decimal number 65.8246 in word form is; tens + 5 ones + 8 tenths + 2 hundredths + 4 thousandths
<h3>How to express decimal numbers?</h3>
A decimal is a number that consists of a whole and a fractional part. Decimal numbers lie between integers and represent numerical value for quantities that are whole plus some part of a whole.
Now, we are given the decimal number 65.824 to write in words. This can be written as;
6 tens + 5 ones + 8 tenths + 2 hundredths + 4 thousandths
The reason for the above is that we can rewrite the given decimal in fraction form as;
60 + 5 + 8/10 + 2/100 + 4/1000

Lets say our number is 237x8
2+3+7+8+x should be divisible by 6.
20+x should be divisible by 6.
x=4
