Answer:

$220

Step-by-step explanation:

Let one year ago, worth of a professional basketball player's autograph=x

After  increasing    worth by 30%

Now, worth of  a professional basketball player's autograph=$286

We have to find the worth of   a professional basketball player's autograph a year ago.

30% of x=\frac{30}{100}\time x=\frac{30x}{100}

According to question

x+\frac{30x}{100}=286

\frac{100x+30x}{100}=286

\frac{130x}{100}=286

x=\frac{286\times 100}{130}

x=220

Hence, a year ago the worth of  a professional basketball player's autograph=$220

Tyler believes that an 8-sided die can be used to predict whether customers at his store will use a coupon when making their pur
Alik [6]
"1 indicating a coupon and all other outcomes indicating no coupon"
Probability is (number of successful outcomes) / (number of possible outcomes)

Theoretical Probability of rolling a 1: 1/8 

Experimental Probability of using coupons: 4/48  =  1/12

So, the experimental probability of a customer using a coupon (that is, 1/12) is smaller than the theoretical probability of rolling a 1 (that is, 1/8).

The sum of two non-zero numbers a and b equals the sum of their reciprocals. If a+b≠0, what is the product of the two numbers?
Vadim26 [7]

Answer:

ab = 1

Step-by-step explanation:

A Reciprocal of a number is a number which when multiplied by the original number yields the multiplicative number, 1.

So the reciprocal of x would be x⁻¹ or ¹⁄ₓ

The information we are given states that the sum of the two non-zero numbers a and b equals the sum of their reciprocals.

So we can write this into an equation and solve,

(See image)

Once we solve, we get the equation (ab-1)(a+b) = 0

We are given info that a+b≠0

So for the above equation to be true, ab-1 has to equal 0

For <em>this</em> to be true, the product ab must equal 1
