A three digit number is formed at random using the digits

Mathematics

1 answer:

kramer3 years ago

3 0

Answer:

2/3, or 66.7%

Step-by-step explanation:

There are 2 options for the first digit (3 or 4).

After the first digit is selected, it cannot be repeated, so there are 2 options left for the second digit.

After the first two digits are selected, there is only 1 option for the third digit.

So there are 4 permutations greater than 300.

The total number of permutations is 3! = 6.

So the probability is 4/6 = 2/3.

What is the radian measure of 205°? Express your answer as a fraction.

V125BC [204]

The radian measure of 205 degees is $\frac{ 41 \pi }{36}$ radians

Solution:

Given that we have to express 205 degrees as radian

To convert from degrees to radians use the following:

$x^{\circ} \times \frac{ \pi}{180}$

where x is the value in degrees to be converted

Here, x = 205 degrees

Substituting we get,

$\rightarrow 205 \times \frac{ \pi }{180}\\\\\rightarrow 41 \times \frac{ \pi }{36}\\\\\rightarrow \frac{41 \pi}{36}$

Thus the radian measure of 205 degees is $\frac{ 41 \pi }{36}$ radians

You earn $250 per month from your part-time job. You are in a kayaking club that costs $20 per month, and you save at least $100

Olegator [25]

Answer:

Amounts in the intervall $130 \leq c \leq 230$

Step-by-step explanation:

We will take the variables c and s, where

c = amount to spend that month

s = savings of the month.

Since each month we save at least 100, we know that

$0 \leq s \leq 100$

Moreover, we earn $250 per month and we spend $20 in a kayaking club, which tells us that

$250=20+s+c$

and so

$230-s=c$

By multiplying by -1, the first inequality also tells us that

$-100 \leq -s \leq 0$

Consequently by adding 230 to the inequality, we get that

$230-100 \leq 230-s \leq 230\\\\\Rightarrow 130\leq c \leq 230$
