Answer:
Probability of choosing one club and one spade = 0.6025
Step-by-step explanation:
Total number of cards= 52 cards
For the first event
Probability of choosing a club
Toatal club = 13 cards
Probability of choosing a club
= 13/52
Probability of choosing a club
= 1/4
Probability of choosing a club
=0.25
For the second event
Probability of choosing a spade
Toatal spade = 13 cards
Probability of choosing a spade
= 13/52
Probability of choosing spadep
= 1/4
Probability of choosing a spade = 0.25
Probability of both = 0.25*0.25
Probability of both = 0.6025
Answer:
3x²+11x+20
Step-by-step explanation:
x(3x+5)+2(3x+5)
3x²+5x+6x+20
3x²+11x+20
For this case we must write in algebraic symbology the expression described above:
We have an equation, then:
- x squared plus y squared:
- minus 2x plus 7y plus 1:
- equals zero:
We construct the equation:
Answer:
<em><u>Total Cost : 1800</u></em>
<u><em>12 dollars * 16 hours = 192 dollars earned</em></u>
<u><em>0.2 percent * 192 = 38.4 dollars saved</em></u>
A.<u><em>She earns 192 dollars every week</em></u>
B. she will save <em><u>38.4 dollars * 7 weeks = 268.8 </u></em> dollars in a week.
C. 7 days times 4.3 weeks = 30.1 days. <em><u>30.1 days * 38.4 = 1,155.84 dollars every month.</u></em>
D. it will take her about <em><u>2 months</u></em> to save the money. <em><u>To be exact: 1.6 months.</u></em>
Hope this helped!
D) a reflection in the line y = x
