A customer bought a car and paid $1,080 in sales tax.The rate is 6%?

Ghella [55]

The price of car is $18000

Step-by-step explanation:

Given

Sales tax on car = $1080

Rate = 6%

Let x be the price of the car

We know that as the rate of sale tax is 6%, 6% of x is 1080

Using mathematical notation

0.06x = 1080

Dividing both sides by 0.06

$\frac{0.06x}{0.06} = \frac{1080}{0.06}\\\\x = 18000$

Hence,

The price of car is $18000

Help please!??!!?!?

Answer:

a) CP = SP/1.1

b) CP = $59.50

c) GST = $5.95

Step-by-step explanation:

a) Divide by the coefficient of CP.

SP = 1.1×CP

CP = SP/1.1

b) Use the formula with the given value.

CP = $65.45/1.1 = $59.50

c) You can do this two ways: subtract CP from SP, or multiply CP by 0.1.

GST = SP -CP = $65.45 -59.50 = $5.95

GST = CP×0.10 = $59.50 × 0.10 = $5.95

A medical device company knows that 11% of patients experience injection-site reactions with the current needle. If 4 people rec

Orlov [11]

Answer: 0.6274

Step-by-step explanation:

Given: The proportion of patients experience injection-site reactions with the current needle : p=0.11

Sample size : n= 4

Let x be a binomial random variable that represents the people get an injection-site reaction.

Binomial probability formula: $P(X=x)= ^nC_x p^x(1-p)^{n-x}$

The required probability : P(x=0)

$=\ ^4C_0(0.11)^0(1-0.11)^4\\\\=(1)(1)(0.89)^4\\\\=0.62742241\\\approx0.6274$

Hence, the probability that none of the 4 people get an injection-site reaction = 0.6274

PLEASE HELP ME!!!!!!!

Viefleur [7K]

Answer:

Step-by-step explanation:

x^2 + 2x = 6x+45

x^2 -4x -45 =0

x^2 - 5x +9x -45 =0

x(x-5) +9 (x-5)=0

(x-5)(x+9)=0

x = 5, -9

x = 5; measure of exterior angle = 5^2+2(5) = 35

x=-9; measure of exterior angle = (-9)^2 + 2(-9) = 63
