Answer:
5 cats, 1 fish and 94 birds
Step-by-step explanation:
Let
- c be the number of cats;
- b be the number of birds;
- f be the number of fish.
A kid bought 100 toy animals, then
If a cat costs $10.00, then c cats cost $10c.
If a fish costs $3.00, then f fish cost $3f.
If a bird costs $0.50, then b birds cost $0.5b.
In total,
We get the system of two equations:
From the first equation:
Substitute it into the second equation:
Number f must be a whole number greater than 0, so
Number c must be a multiple of 5, thus the only possible value for c is 5.
When c = 5, then
Answer:
5/4
Step-by-step explanation:
start from 0,0 then go up 5 and right 4
Answer:
Step-by-step explanation:
We are given the following in the question:
The organizers estimate that the variation in distance flown by the athletes will be σ = 10 meters.
This will be stated by the null hypothesis.
It was claimed that the organizers are underestimating the variation and the variation in distance is greater than 10.
This will be stated by the alternate hypothesis.
The parameter for the given hypothesis is standard deviation, 
.
Answer:
60%
Step-by-step explanation:
he gave away 2/5 which is 40%. 100%-40% is 60%
Q + s = q + 1, we know because you can substitute s for 1 according to the number line.
