We have 3 9/16 = 57 / 16 = 3.56;
4 3 / 5 = 23/5 = 4. 60;
4 7/8 = 39 / 8 = 4.87;
4 1 / 2 = 9 / 2 = 4.50;
3 1 / 2 = 7 / 2 = 3.50;
3 3 / 8 = 24 / 8 = 3;
Only, 4.50 > 3.56 and 4.50 < 4.60;
Our number is 4 1 / 2.
Answer:
Step-by-step explanation:
This is simply a units conversion problem. It gives us for the number of passengers, the number of seats per carriage and the number of carriages per train. To change the units from passengers to trains without changing the value, we use the multiplicative identity (that is, 1).
350000 passengers
(350000 passengers) * 1
(350000 passengers) * ((1 carriage)/(32 passengers)) * ((1 train)/(15 carriages)
[note: passengers and carriages cancel. Leaving only trains]
(350000)*(1/32)*(1/15) trains [note: I write this way to paste into MS Excel]
729.1667 trains [oh, but don’t just round this number either up or down]
729 full trains can carry 729*32*15 = 349920 passengers
730 full trains can carry 730*32*15 = 350400 passengers
Now, we can say that 730 trains are adequate to carry 350000 passengers.
Answer:
<h2>
B. <u>g(x) = 4x²</u></h2>
Step-by-step explanation:
f(x)= x²
the shape of f (x ) and g( x ) is same.
and those graphs lower point is ( 0 , 0 )
therefore,
will, g(x) = kx² (k ∈ real numbers)
the g(x) graph goin through the point ( 1 , 4 )
therefore,
4 = k × 1²
k = 4
∴ <u>g(x) = 4x²</u>
Answer:
The sample size for the data set = 56
Step-by-step explanation:
The sample size or number of individuals (n) is gotten from a histogram by summing up the total frequencies of occurrences.
In this example, the frequencies are: 2 4 6 8 10 12 14
Therefore, the sample size (n) is calculated as follows:
n = 2 + 4 + 6 + 8 + 10 + 12 + 14 = 56
Therefore the sample size for the data set = 56
Answer:
M = 7
Step-by-step explanation:
6m + 2(6 + 7m) = -128
6m + 12 + 14m = -128
20m + 12 = -128
Subtract 12 both sides
20m = 140
Divide by 20 both sides
M=7
