Step-by-step explanation:
This is confusing, what does g(x) equal? There's a bunch of random numbers there. I'll just assume.
They stated that f(x) needs to exceed g(x), so make an inequality plugging in the values
You see, function f(x) needs to be higher than function g(x)
Subtract 7x from both sides to get:
Divide both sides by -4, when you divide by a negative number the signs switch so it is now less than.
x < -1.5
And obviously that's not an answer up there, so you made a mistake stating the values of the functions
<span>The probability that a house in an urban area will develop a leak is 55%. if 20 houses are randomly selected, what is the probability that none of the houses will develop a leak? round to the nearest thousandth.
Use binomial distribution, since probability of developing a leak, p=0.55 is assumed constant, and
n=20, x=0
and assuming leaks are developed independently between houses,
P(X=x)
=C(n,0)p^x* (1-p)^(n-x)
=C(20,0)0.55^0 * (0.45^20)
=1*1*0.45^20
=1.159*10^(-7)
=0.000

Answer: 0.47
Step-by-step explanation:
0.47% = 0.0047 in decimal form. Percent means 'per 57'. So, 67Inches means 0.47 per 100 or simply 0.47/100. If you divide 0.47 by 100, you'll get 0.0047 (a decimal number).
Answer:
a percent is a variable of proportionality describing the part of the whole.
