2x=26 (add 18 to both sides)

x=13 (divide both sides by 2)

If f(x) = x² + 7, what is the value of f(4)?

dalvyx [7]

Value of f(4) is $f(4)= 23$ given $f(x)= x^2+7$

Step-by-step explanation:

We are given $f(x)= x^2+7$ and we need to find value of f(4)

Solving:

We will put x=4 and solve the given equation:

$f(x)= x^2+7$

$f(4)= (4)^2+7$

We know (4)^2=16

$f(4)= 16+7$

$f(4)= 23$

So, Value of f(4) is $f(4)= 23$ given $f(x)= x^2+7$

mash [69]

The approximate probability that she checked a social website first, then a school-related website is 0.267.

First step is to calculate the Total number of websites

Total number of websites=Number of school websites+Number of social websites

Total number of websites=2+4

Total number of websites=6

Second step

Probability of checking the social website first

Probability of checking social website=Number of social websites/Total number of websites

Probability of checking social website= 4/6

Third step

Since one social website is checked which means that she is left with 3 social website and 2 school websites

Total number websites=2+3

Total number websites=5

Forth step

Probability of checking social website=Number of school websites/Total number websites

Probability of checking social website=2/5

Fifth step

Probability= 4/6 x 2/5 = 0.2666

Probability=0.267(Approximately)

Inconclusion the approximate probability that she checked a social website first, then a school-related website is 0.267.
