What is the probability that a two-digit number selected at random has a tens digit less than its units digit

Mathematics
1 answer:
Reika [66]2 years ago

The probability that a two-digit number selected at random has a tens digit less than its units digit is 0.2667 (4/15).

A=24B=90\\\\P=A/B\\\\P=24/90\\p=4/15

There are 90 two-digit numbers (99-9). Of these, six numbers are divisible by 15 (15, 30, 45, 60, 75, 90). This is also divisible by 5. Therefore, the preferred case is 30-6 = 24. Therefore, the required probability is 24/90 = 4/15.

The probability of an event can be calculated by simply dividing the number of favorable results by the total number of possible results using a probabilistic expression. Whenever you are uncertain about the outcome of an event, you can talk about the probability of a particular outcome, that is, its potential.

If M is the midpoint of PQ and X is the midpoint of PM then PX = a PQ Which statement is True? a is equal to 1 a is equal to 1/2
garik1379 [7]

Answer:

D. a is equal to  \frac{1}{4}

Step-by-step explanation:

Let us assume that segment PQ is 8 units, so that its midpoint M is at 4 units to both P and Q.

Given that X is the midpoint of PM, this implies that X is at 2 units to both P and M.

Then;

PX = aPQ

⇒   = a x 8

      = 8a

Therefore, a must be equal to \frac{1}{4}, so that;

PX = 8a

     = 8 x  \frac{1}{4}

     = 2 units

Thus, a is equal to  \frac{1}{4} is the correct option.

an initial deposit of $200 is made into an account that pays 4.2% annual interest. What is a model to represent the balance in t
Sholpan [36]
You would use the equation y = A(1+r)^t 

A = Original amount = 200
r = interest rate = 0.042 (when converted from percent to decimal)
t = time = x 

Plug them in and you get the model: y = 200(1+0.042)^x 

or just simplify the parentheses to (1.042)

you want to deposit $15,000 in a bank at an interest rate of 7% per year what is the future value of this money after 3 years
Assoli18 [71]
AMOUNT DEPOSITED: $15k ($15,000)
INTEREST RATE PER YEAR: 0.07% (7%)

STEPS:
→Multiply the amount deposited ($15k) by the interest rate per year (7%).
15,000 * 0.07
= $1,050 (interest earned in 1 year)

→Multiply the interest earned from the first year ($1,050) by the amount of years that you want to calculate (3 years)
$1,050 * 3
=3,150 (interest earned in 3 years)

→ Add the interest earned (in 3 years, in this particular equation) to the amount that you deposited ($15k)
$15,000 + $3,150
=$18,150

FINAL ANSWER: $18,150
