Given: f(x) = 1/x (<- that’s division sign btw)

Jlenok [28]

To evaluate $(g \circ f)(0)$ , you'd start by rewriting this as $(g \circ f)(0) = g\big(f(0)\big)$ and your first step of evaluation is to evaluate $f(0)$ .

When you evaluate $f(0)$ , you have the following:

$f(0) = \dfrac{1}{0}$

and this is undefined. Since you cannot perform the first step of the evaluation, you cannot evaluate $(g\circ f)(0)$ .

Use the relative frequency approach to estimate the probability of the event. In a certain class of students, there are 8 boys f

In-s [12.5K]

Answer:

$P\text{Student will be from Kenilworth}\approx 0.256$

Step-by-step explanation:

We have been given that that there are 8 boys from Wilmette, 5 girls from Kenilworth, 9 girls from Wilmette, 5 boys from Glencoe, 5 boys from Kenilworth and 7 girls from Glenoce.

The total number of students from Kenilworth is 5 boys plus 5 girls that is 10 students.

The total number of students in the class would be $8+5+9+5+5+7=39$

$\text{Probability}=\frac{\text{Number of favorable outcomes}}{\text{Total number of possible outcomes}}$

$P\text{Student will be from Kenilworth}=\frac{\text{Number of student from Kenilworth}}{\text{Total number of students}}$

$P\text{Student will be from Kenilworth}=\frac{10}{39}$

$P\text{Student will be from Kenilworth}=0.2564102564$

$P\text{Student will be from Kenilworth}\approx 0.256$

Therefore, the probability, that the student will be from Kenilworth, is approximately 0.256.

Make x the subject of each of the following formulae:<br> a) y = 2x - 1<br><br> b) y = x/2 + 3

julsineya [31]

Answer:

$1)y = 2x - 1 \\ y + 1 = 2x \\ \frac{y + 1}{2} = x \\ 2)y = \frac{x}{2} + 3 \\ y - 3 = \frac{x}{2} \\ 2(y - 3) = x \\ 2y - 6 = x \\ thank \: you$
