Answer:
10000 metres
Step-by-step explanation:
You calculate by multiplying the number of metres in the ratio by 10 centimetres.
Your answer should come out to 10000 (10:10000)
Answer:
Check the attached image below.
Step-by-step explanation:
Kindly check the attached image to get the step by step solution to the question above.
So you have to make two equations. Let's say x stands for shirts and y stands for pants. 4x+3y=85.50. The second equation would be, 5y=115-3x. Since you need one of them to have x= or y=, you need to change it to that form. y=. Then you do substitution and solve which leaves you with:
Shirts are $7.50
Pants are $18.50
Answer:
The graph shows that when x =3 both
and 5 – x equal 2
Step-by-step explanation:
The equation 13x + 1 = 5 – x can be solved by graphing y = 13x + 1 and y = 5 – x.
From the graph, the two lines representing the two equations intersect at (3,2).
This implies that the solution to the system
and
y=5-x
is x=3, y=2
Hence the value of the two functions equals 2 at x=3.
Answer:
Option a
Step-by-step explanation:
Given two normal distribution samples
I group has 106 as mean and 8.5 as std deviation with sample size = 60
II group has 121 as mean and 6.3 as std deviation with sample size =38
We find mean difference =-15
For margin of error finding, we have to find the combined std error for the difference
Variance of difference = Sum of variances
STd error for difference = 1.50
Hence for 99% margin of error =2.58(1.50)
= 3.87
