Find f(1/4) when f(x)=2x^2+9x-7

1 answer:

Semmy [17]2 years ago

$f (\frac{1}{4}) = 2( \frac{1}{4} ) + 9 (\frac{1}{4}) - 7$
$= \frac{2}{4} + \frac{9}{4} - 7$
$= \frac{2 + 9 - 28}{4}$
$f( \frac{1}{4} ) = \frac{17}{4}$

What is the probability that a resident reports high satisfaction, given that the resident is a renter?

dem82 [27]

Answer:

The probability that a resident reports high satisfaction while the resident is a renter is Option(a) $13.7\%$

Step-by-step explanation:

Given:

Levels of satisfaction

High Medium Low Total

Owners $26$ $34$ $18$ $78$

Renters $15$ $12$ $5$ $22$

Total $41$ $46$ $23$ $110$

The Resident is a renter.

Step 1:

To find the probability that a resident reports high satisfaction.

P(Renter- higher satisfaction)= Higher Satisfaction by render ÷ Total level of satisfaction

$=\frac{15}{110}$

$=0.137$

$13.7\%$ is the probability that a resident reports high satisfaction.

Therefore, Option (a) is a correct answer.

(1/4 * 40) + (1/4 * 8)

10 + 2
