Product means multiplication. So the equation would be xy ≤ 4.
After 10 hours of work, she makes a total of $500
I think there is a little error in your question. I guess You mean 60 vaccinations instead of 606060. I solved using 60 vaccinations.
Answer:Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.
Step-by-step explanation:
STEP 1
Let number of polio vaccines be x
and number of measles vaccine be y
such that
total does of 60 vaccinations be expressed as
x+y = 60---- equation 1
And number of doses for both vaccine to total 184 doses taken be expressed as
4x + 2y= 184 ---- equation 2
Step 2--- solving
x+y = 60---- equation 1
4x + 2y= 184 ---- equation 2
Making x the subject of formula in equation 1 and substituting it in equation 2
x= 60-y
4(60-y) +2y- 184
240-4y+2y=184
240-184= 4y-3y
56= 2y
y= 58/2 = 28
To get x , put the value of y=28 in equation 1 and solve
x+y=60
x=60-28
x=32
Therefore Dr. Potter gave 32 polio vaccines and 28 measles vaccinations that year.
Answer:
-1/35 = -.0286
Step-by-step explanation:
-5x * 7 = 1
-35x = 1
<u>x = -1/35</u>
Probabilities are used to determine the chances of events
The probability that the first erroneous bit is the 28 bit is 0.0076
<h3>How to determine the probability</h3>
The given parameter is:
p =1% --- the probability that a bit has errors
The probability that the first erroneous bit is the 28 bit means that the first 27 bits do not have errors.
So, we have:
![Pr = (1 - p)^{27} * p](https://tex.z-dn.net/?f=Pr%20%3D%20%281%20-%20p%29%5E%7B27%7D%20%2A%20p)
The equation becomes
![Pr = (1 - 1\%)^{27} * 1\%](https://tex.z-dn.net/?f=Pr%20%3D%20%281%20-%201%5C%25%29%5E%7B27%7D%20%2A%201%5C%25)
Evaluate
![Pr = 0.0076](https://tex.z-dn.net/?f=Pr%20%3D%200.0076)
Hence, the probability that the first erroneous bit is the 28 bit is 0.0076
