Answer:
Step-by-step explanation:
To find how far she can walk in 3 minutes, we need to find how fast she can walk in 1 minutes. We do this by dividing the distance she walked by the time she walked. Lets do so.
3200/24=133.33
She walks 133.33 meters per minute. Now to find her distance in 3 minutes w multiply this number by 3.
133.33*3=400
Barbra walks 400 meters every 3 minutes.
4x-3=9x-13
10=5x
2=x
So these functions intersect when x=2.
Answer:
Step-by-step explanation:
We will solve the given expressions and find the answer in decimals.
1). 
= 
= 5.4 - 2.8
= 2.6
2). 
= -3.3 + 0.35
= -2.95
3). 
= -3.125
4). (-4.5) × (-2.3) = 10.35
Solution of the expressions in the increasing order will be,
-3.125 < -2.95 < 2.6 < 10.35
To find out all of the possible combinations, just multiply the amount of each variable:
4*2*5 = 40
There are 40 different combinations consisting of a sandwich, soup, and drink.
Answer:
5%
Step-by-step explanation:
Hospital A (with 50 births a day), because the more births you see, the closer the proportions will be to 0.5.
Hospital B (with 10 births a day), because with fewer births there will be less variability.
The two hospitals are equally likely to record such an event, because the probability of a boy does not depend on the number of births
