5.1 is greater than 5.099, because the value of the 1 in 5.1 is more than the value of the 99 in 5.099.
[tex]\begin{gathered} 5.1=5+0.1=5+\frac{1}{10}=5+\frac{100}{1000} \\ 5.099=5+0.099=5+\frac{99}{1000} \end{gathered}[/tex]The value of 1 in 5.1 is 0.1, while the value of the 99 in 5.099 is 0.099.
Since 0.1 is bigger than 0.099, then 5.1 is bigger than 5.099.
Also, 5.1 is greater than 5.099 because a bigger number on 5.1 (which is 1) is closer to the decimal point compared to 5.099 (1 is bigger than 0). the closer a decimal is to the decimal point the higher its value.
The average number of babies born at a private hospital's maternity wing is 6 per hour. What is the probability that three babies are born during a particular 1-hour period in this maternity wing?
If the average number of babies born at a private hospital's maternity wing is 6 per hour. The probability that three babies are born during a particular 1-hour period in this maternity wing is 0.09.
How to find the Probability?Mean = 6 per hours
Number of babies = 3 babies
Hence,
Now let determine the probability
Let x represent the probability
Pr(X=3) = e^-6 × 6^3 ÷ 3!
Pr(X=3) =0 .535410 ÷ 6
Pr(X=3) = 0.089
Pr(X=3) =0.09 (Approximately)
Therefore we can conclude that 0.09 is the probability.

8. (15 pts) Explain clearly why Graph A IS a function, while Graph B is NOT a function. (Youcan indicate where the graphs pass or fail and reference that in your explanation)
We can see two graphs and we need to determine the reason why graph A IS a function, and graph B is NOT a function.
To achieve that, we can proceed as follows:
1. A function is a relation in which for each element of the domain we have only (exactly) one element of the range.
2. The domain of a function is the values for x for which the function is defined, and the range is those values for y that result when the function takes values for x and after following the rule of the function (the values for which the function is defined).
3. To determine if a graph is a function, we can use the vertical line test. Given the above definitions, this test tells us that if a vertical line passes through a graph at more than a point, then the relation is NOT a function.
4. Now we can use the Vertical Line Test on each graph as follows:
Graph A:As we can see from the graph, the vertical line passes through only one point (one value for y associated to x). We can see that the open circle indicates that the function is not defined for the value while the solid circle indicates that the function is defined for that value.
For instance, for x = -1 the value of the function is y = 0 (and not y = -1 - see the open circle). We have a similar case for x = 1 (y = 1) (not y = 0).
Therefore, graph A IS a function.
Graph B
In this case, we can say that the vertical line passes through more than one point in most of the values. However, we can say that there are some values where the line passes through one point - from x = -3 to x = -2 (included) -, and for values greater than 2 (x>2).
However, since the vertical line test indicates that the line passes through more than a point (there are more than a value, y, for each x) then Graph B is NOT a function.
Therefore, in summary, we can say that using the method of the vertical line test, Graph A IS a function, while Graph B is NOT a function.

The management of the UNICO department store has decided to enclose a 903 ft2 area outside the building for displaying potted plants and flowers. One side will be formed by the external wall of the store, two sides will be constructed of pine boards, and the fourth side will be made of galvanized steel fencing. If the pine board fencing costs $7/running foot and the steel fencing costs $4/running foot, determine the dimensions of the enclosure that can be erected at minimum cost.
The dimensions of the enclosure that can be erected at minimum cost are 21.25 feet by 42.50 feet
How to determine the dimensions of the enclosure that guarantees the minimum costFrom the question, the given parameters are
Area = 903 square feet
Shape = rectangle
From the question, we understand that:
One side of the area would be enclosed by the external wall of the store
If the dimensions of the area are Length (L) and Width (W), then we have
Area = LW
Perimeter = 2L + W
Rewrite as
A = LW
P = 2L + W
Substitute 903 for A in A = LW
LW = 903
Make W the subject
W = 903/L
Substitute W = 903/L in P = 2L + W
P = 2L + 903/L
Differentiate the equation
So, we have
P' = 2 - 903/L²
Set to 0
2 - 903/L² = 0
So, we have
903/L² = 2
This gives
L² = 903/2
Divide
L² = 451.5
Take the square roots
L = 21.25
Substitute L = 21.25 in W = 903/L
W = 903/21.25
Evaluate
W = 42.50
Hence, the dimensions of the enclosure are 21.25 feet by 42.50 feet

during the winter olympics the us curling team scored 2 points more than the canadian team. the canadian curling team scored 4 points more than the norwegian team. altogether the three teams scored a total of 208 point. how many points did the canadian team scored?
Answer:
70 points
Step-by-step explanation:
u = US points
c = Canadian points
n = Norwegian points
u = c + 2
n = c - 4
208 = u + c + n
208 = ( c + 2 ) + c + ( c - 4 ) = 3c - 2
Isolate c:
208 = 3c - 2
210 = 3c
c = 70

if once taxi fare was $7.65 how many miles did he travel in the taxi a taxi company charges $2.25 for the first mile and then $0.20 per mile for additional mile or f equals $2.25 + $0.20(m -1) where f is the fair and m is Adam's number of miles
Answer:
28 miles
Explanation:
The equation that describes the relationship between the fare and the number of miles is:
f = 2.25 + 0.20(m - 1)
Where f is the fare and m is the number of miles.
So, if the taxi fare was $7.65, we can replace f by 7.65. Then:
7.65 = 2.25 + 0.20(m - 1)
Therefore, we can calculate the number of miles by solving the equation for m. So, subtracting 2.25 from both sides:
7.65 - 2.25 = 2.25 + 0.20(m - 1) - 2.25
5.4 = 0.20(m - 1)
Dividing by 0.20, we get:
[tex]\begin{gathered} \frac{5.4}{0.20}=\frac{0.20(m-1)}{0.20} \\ 27=m-1 \end{gathered}[/tex]Finally, add 1 to both sides:
27 + 1 = m - 1 + 1
28 = m
So, he travels 28 miles in the taxi

Signs are placed at regular intervals along a mountain road to indicate altitude. At Grinbrir Lodge, the sign indicates an elevation of 876 meters. But 17 kilometers down the road, another sign indicates that the elevation is 672 meters. What is the average elevation change per kilometer traveled from the Lodge
Answer:
-12 m/km
Step-by-step explanation:
You want to know the average elevation change per kilometer given the elevation changes from 876 meters to 672 meters over a distance of 17 kilometers.
Rate of changeThe average elevation change per kilometer is found by dividing the elevation change by the number of kilometers. The elevation change is the difference between the ending elevation and the starting elevation.
rate of change = ((end elevation) -(start elevation))/(distance)
= (672 m -876 m)/(17 km) = (-204 m)/(17 km) = -12 m/km
The average elevation change is -12 meters per kilometer traveled from the lodge.

Expressing both dimensions in the same unit, we can find the average grade of the road to be ...
(-12 m)/(1000 m) = -0.012 = -1.2% . . . . . average grade of the road

In order to add these numbers, first let's write all of them with the same number of decimal places:
17.34 = 17.340
8.03 = 8.030
0.009 = 0.009.
Then, let's add all algarisms that are in the same position in each number:
0 + 0 + 9 = 9
4 + 3 + 0 = 7
3 + 0 + 0 = 3
7 + 8 + 0 = 15 (5 plus 1 to next algarism)
1 + 0 + 0 (+ 1) = 2
So the final result is 25.379.
