Help with top one please

HACTEHA [7]

Short answer: 39
y = 7x - 3
f(x) = y = 7x - 3 Though there are some slight differences between f(x) and y, it is safe to say that f(x) acts (in this case) as a y value. So the question now is what does y(6) mean?

y(6) means exactly the same thing as what f(6) would mean. The both mean that where ever you see an x, put in a 6.

So y(6) means 7x - 3 = 7*6 - 3 = 39

Answer:

<em>Expected number of students would have a driver's license = 6</em>

Step-by-step explanation:

<u><em>Explanation</em></u>:-

Given data In a class of 25 students, 15 of them have a driver's license

The sample proportion

$p = \frac{x}{n} = \frac{15}{25} = 0.6$

Let 'X' be the binomial distribution

Given sample size 'n' = 10

<em>mean of the binomial distribution or expected number of students would have a driver's license</em>

μ = n p

= 10 × 0.6

= 6

<u><em>Conclusion</em></u>:-

<em>Expected number of students would have a driver's license = 6</em>

In the collection of beads, StartFraction 4 Over 20 EndFraction are blue. Which model shows the percent of beads that are blue?

jolli1 [7]

Option B model shows the percent of beads that are blue.

Solution:

Fraction of beads blue = $\frac{4}{20}$

To convert it into percent multiply the fraction by 100.

$$\text {Percent of} \ \frac{4}{20}=\frac{4}{20}\times 100\%$

$$=\frac{4\times 100}{20} \%$

Cancel the common factors, we get

= 20%

$$=\frac{20}{100}$

This means total number of boxes 100 and shaded in blue color 20.

Therefore option 2 represents $\frac{20}{100}$ .

Hence option B model shows the percent of beads that are blue.
