1/10 of an hour (D) is correct. Hope this helped :)
Answer:
1 / 13
Step-by-step explanation:
The total number of cards in a deck = 52
The total number of aces in a deck = 4
Since selection is drawn with replacement, then probability of drawing a certiaj number of card from the deck will be the same each time a selection is made :
Probability = required outcome / Total possible outcomes
The required outcome = number of aces = 4
Total possible outcomes = total number of cards = 52
P(drawing an ace) = 4 / 52 = 1 /13
Step-by-step explanation:
(3 × 10) × 8 = 3 × (10 × 8)
It's an Associative Property of addition:
<em>(a + b) + c = a + (b + c)</em>
<em></em>
Check it:
Left side: (3 × 10) × 8 = 30 × 8 = 240
Right side: 3 × (10 × 8) = 3 × 80 = 240
CORRECT
7. The smaller number is 7 because 7x5=35
35+1+7=43
Since 1000m=1km, we have 100000m/hr for the car. 75/100000 gets the fraction of how long in an hour it would take. Since there are 60*60=3600 seconds in an hour, we multiply 75/100000 by 3600 to get 2.7 seconds
