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>

What’s the correct answer for this question?
Brut [27]

Answer:

C.

Step-by-step explanation:

First finding height using Pythagoras theorem

(H)²=(B)²+(P)²

8.2²=5.4²+P²

P² = 67.24 - 29.16

P² = 38.08

P = 6.2

Now

Volume of cone = (1/3)πr²h

= (1/3)(3.14)(5.4)²(6.2)

= (1/3)(567.9)

= 189.2 cm³

Gianna has a two $3,000 one year CDs at different banks. Each compounds
sertanlavr [38]

Answer:

Option D

Step-by-step explanation:

To calculate compound interest we will use the formula :

A=P(1+\frac{r}{n})^{nt}

Where,

A = Amount on maturity

P = Principal amount = $3000

r = rate of interest = 8.4% = 0.084

n = number of compounding period = Monthly = 12

t = time = 1 year

Now put the values in the formula.

A=3000(1+\frac{0.08}{12})^{(12)(1)}

   = 3000(1+0.007)^{12}

   = 3000(1.007)¹²

   = 3000 × 1.08731066

   = 3261.93198 ≈ $3261.93

While the other bank compounds interest daily.

Therefore, n = 365

Now put the values in the formula with n = 365

=3000(1+\frac{0.084}{365})^{(365)(1)}

=3000(1+0.00023014)^{365}

=3000(1.00023014)^{365}

= 3000 × 1.08761958

= 3262.85874 ≈ $3262.86

Difference in the ending balance = 3262.86 - 3261.93

                                                       = $0.93

The difference in the ending balances of both CDs after one year would be $0.93.
