Whats the difference of 89,24&17

STALIN [3.7K]

I interpret the first number to be 89.24, so 84 and 24 hundredths.

The difference would be by how many numbers they differ, so we subtract the smaller from the bigger:

89.24-17=12.24

this would be their difference!

your car broke down and the final bill was $306.50. The part that was replaced cost $119 and the charge mechanics labor was 75 p

erastova [34]

Answer:

$\huge\boxed\text{Equation:}$ $\huge\boxed{\text{Equation: }119+75x=306.50}\\$

$\huge\boxed{\text{Hours worked on: } 2.5}$

Step-by-step explanation:

We can create an equation for this problem by converting the words to an equation.

The <em>flat fee</em> was $119. We then add $75 for every hour worked. This means that this becomes $119+75x$ . Since the total cost was $306.50, the equation is $119+75x=306.50$ .

We can now solve for x, the amount of hours worked, to find it’s value.

$119 + 75x = 306.5\\\\75x=187.5\\\\x = 2.5$

Hope this helped!

3 cards are drawn from a standard deck without replacement. What is the probability that at least one of the cards drawn is a re

Rudik [331]

Answer: $\dfrac{15}{17}$

Step-by-step explanation:

Total number of cards in a deck = 52

Number of red cards = 26

Number of cards not red =

Number of ways to draw not red cards = $^{26}C_3$

Total ways to draw 3 cards = $^{52}C_3$

The probability that none of three cards are red = $\dfrac{^{26}C_3}{^{52}C_3}$

$=\dfrac{\dfrac{26!}{3!(26-3)!}}{\dfrac{52!}{3!(52-3)!}}$ [∵ $^nC_r=\dfrac{n!}{r!(n-r)!}$ ]

$=\dfrac{\dfrac{26\times25\times24\times23!}{(23)!}}{\dfrac{52\times51\times50\times49!}{3!(49)!}}=\dfrac{2}{17}$

Now , the probability that at least one of the cards drawn is a red card = 1- Probability that none cards are red

$=1-\dfrac{2}{17}=\dfrac{17-2}{17}=\dfrac{15}{17}$

Hence, the required probability = $\dfrac{15}{17}$
