Answer:
35 minutes
Step-by-step explanation:
<u><em>Martin can run a kilometer in 7 minutes. If he keeps at this pace how many minutes will it take him to run a 5k race?</em></u>
<u><em /></u>
To solve this, we simply need to use proportion.
Let x represent the number of minutes that will take Martin to run a 5 kilometer race
1 kilometer = 7 minutes
5 kilometer = x
cross-multiply
1 × x = 7 × 5
x = 35 minutes
Therefore, it will take Martin 35 minutes to run a 5 kilometer race.
Whether the events are dependent or not, the rule for conditional probability applies:
P(a|b) = P(a∩b)/P(b)
P(a|b)×P(b) = P(a∩b)
0.25×0.4 = P(a∩b) = 0.1
The appropriate choice is
C. 0.1
Cost of flakes per ounce is $0.1204 ,
a. If a box cost $77.05 then approximately 640 pounds of flakes are in box.
b. Cost of 2-pound flakes is $3.8525.
As given,
Cost of flakes = $0.1204/ounce
a.
Cost of a box =$77.05
1 pound =16 ounces
$0.1204 =1 ounce
⇒$77.05 =77.05 /0.1204
= 639.95
≈ 640 ounces
= 40 pounds
b. Cost of 2 pounds =(77.05 /40)× 2
= $3.8525
Therefore, there are
a. Approximately 640 pounds of flakes are in box.
b. Cost of 2-pound potato flakes is $3.8525.
