Answer:
I think the reference ratio given is wrong so the right one is
8:508:508:5
Step-by-step explanation:
Given that,
8:58:58:5
We want to find which of the option is equivalent to the given ration
Option A.
16:1016:1016:10
Divide each of the ration by
Then,
16÷2:1016÷2:1016÷2:10÷2
8:508:508:5
Option B
50:8050:8050:80
Divide through by 10
50÷10:8050÷10:8050÷10:80÷10
5:805:805:8
Option C
48:3048:3048:30
Divide through by 6
48÷6:3048÷6:3048÷6:30÷6
8:508:508:5
Option D
32:2032:2032:20
Divide through by 4
32÷4:2032÷4:2032÷4:20÷4
8:508:508:5
Option E
64:3564:3564:35
Divide through by 8
64÷8:3564÷8:3564÷8:35÷8
This doesn't have a factor
So the ratio still retain
64:3564:3564:35
So to analyse the solution,
I believe the reference ratio given is wrong, so I think the reference ratio about be 8:508:508:5
So, from the option, the equivalent to the given ratio are options A, C, and D
Answer:
130 meters
Step-by-step explanation:
just add an extra zero at the end of 13
We are give the equation of the perimeter of the triangle as follows:
2a + b = 15.7
where b represents the base.
Now, if we want to calculate the length of the base, all we have to do is isolate the b in one side of the equation as follows:
b = 15.7 - 2a
We know that a = 6.3 cm, therefore, the length of the base can be calculated as follows:
b = 15.7 - 2(6.3) = 3.1 cm
Answer:
1/8 and 1/16
Step-by-step explanation:
The negative exponent just means to right the negative inverse.
For example:
4^-2 means 4^2 but in a fraction
the answer would be 1/16
Answer:
It is going to be bell-shaped(normally distributed), with mean 
and standard deviation 
.
Step-by-step explanation:
The Central Limit Theorem estabilishes that, for a random variable X, with mean 
and standard deviation 
, a large sample size can be approximated to a normal distribution with mean and standard deviation 
.
What can we say about the shape of the distribution of the sample mean time?
It is going to be bell-shaped(normally distributed), with mean and standard deviation .
