302400. the amount of seconds in a week divided by 2
Answer:
A rate is a comparison, or ratio, of two quantities with different units. For example, a store sells
3 T-shirts for $15. The comparison $15 to 3 T-shirts is a rate. This rate can also be written as $15 _______
3 T-shirts.
When a rate compares a quantity to one unit of another quantity, the rate is a unit rate.
The rate $15 _______
3 T-shirts is not a unit rate because the rate compares the cost to more than one T-shirt. In a unit
rate, the second quantity (or denominator) should be 1 unit.
A speed limit is a unit rate. For example, the speed limit of 55 miles per hour compares the distance to
1 hour. A speed of 55 miles per hour is equivalent to traveling 55 miles in each 1-hour time span. This rate can also be written as 55 miles/1 hour
Step-by-step explanation:
Multiply the whole number part by the fraction's denominator.
Add that to the numerator
Then write the result on top of the denominator.
Answer:
9/25
Step-by-step explanation:
Our box contains 10 socks. (6, which are black and 4 which are red)
Probability of picking 1 black sock will be 6/10
Number of ways it can occur / Total number of outcomes.
In this question we pick two socks, one black firstly and another black, in the second turn. When we say AND, it means intersection
P (B₁ ∩ B₂) = 6/10 . 6/10
When the events are independent, the probability of the intersection will be the product of the probabilities,
P (B₁ ∩ B₂) = 36/100 = 9/25
