Answer:

y = 6x + 4
Rs. 94

Step-by-step explanation:

Equation for this case is:

⇒ y = 6(x - 1) + 10 as Rs. 10 for the first km and Rs. 6 for the rest (x - 1) km

⇒ y = 6x - 6 + 10 simplifying

⇒ y = 6x + 4 final equation

For x = 15 km we have total of:

y = 6*15 + 4 = 94

Answer:

0.2406 = 24.06% probability that exactly two of the selected major customers accept the plan

Step-by-step explanation:

The customers are chosen without replacement, which means that we use the hypergeometric distribution to solve this question.

Hypergeometric distribution:

The probability of x sucesses is given by the following formula:

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

In which:

x is the number of sucesses.

N is the size of the population.

n is the size of the sample.

k is the total number of desired outcomes.

50 major customers, 15 would accept the plan.

This means that $N = 50, k = 15$

The utility selects 10 major customers randomly (without replacement) to contact and promote the plan.

This means that $n = 10$

a. What is the probability that exactly two of the selected major customers accept the plan

This is P(X = 2).

$P(X = x) = h(x,N,n,k) = \frac{C_{k,x}*C_{N-k,n-x}}{C_{N,n}}$

$P(X = 2) = h(2,50,10,15) = \frac{C_{15,2}*C_{35,8}}{C_{50,10}} = 0.2406$

0.2406 = 24.06% probability that exactly two of the selected major customers accept the plan

Game stop is having a 15% off sale. If the game rocket league is $40 and the sales tax rate is 6.25%, how much would you pay aft

aksik [14]

The buyer will pay $36.125 after the discount and sales tax

Step-by-step explanation:

Given

Price of Rocket league = $40

Discount = 15%

Sales tax = 6.25%

First of all we have to find the discounted price

So,

$Discount = 15\%\ of\ 40\\= 0.15*40\\=6$

The discount is $6.

The discounted price will be:

$Discounted\ price = price - discount\\= 40-6\\= \$34$

The sales tax will be applied on this discounted price now.

So,

$Sales\ tax = 6.25\%\ of\ 34\\= 0.0625 * 34\\=2.125$

So the total price of Rocket league after discount and sales tax will be:

$Final\ price = Discounted\ price + Sales\ tax\\= 34+2.125\\=36.125$

Hence,

The buyer will pay $36.125 after the discount and sales tax

Find the length of the missing sides in the triangle

Alex

Answer:

b. $\displaystyle x ≈ 9,9, y = 7$

Step-by-step explanation:

In a 45°-45°-90° triangle, both legs are congruent $\displaystyle [x],$ whereas the hypotenuse is represented by $\displaystyle x\sqrt{2}.$ So, evaluate:

$\displaystyle hypotenuse \hookleftarrow x\sqrt{2} \\ \\ 9,8994949366... = \boxed{7\sqrt{2}}$

Therefore, you have this:

$\displaystyle 9,9 ≈ x$

I am joyous to assist you at any time.
