Answer:
x=wt of small box y = large box wt
First delivery
5x + 2y = 96 solve for y = (96-5x)/2
Second Delivery
8y + 3x = 163 Substitute for y
8 ( ( 96-5x)/2 ) + 3x = 163 and solve for x
384 - 20x +3x = 163
17x=221
x=13 = small box wt kg y= (96-5x)/2 = large box wt = 15.5 kg
Answer:
6 dimes & 10 quarters
Step-by-step explanation:
Here are the two equations. The first one deals with the numbers of coins. The second one deals with the values of the coins.
d + q = 16
0.1d + 0.25q = 3.1
Solve the first equation for d and plug into the second equation.
d = 16 - q
0.1(16 - q) + 0.25q = 3.1
1.6 - 0.1q + 0.25q = 3.1
0.15q = 1.5
q = 10
d + q = 16
d + 10 = 16
d = 6

Answer:
Tested outcome (difference) is significant.
Step-by-step explanation:
The significance level of 5% (more typically referred to as 95%) corresponds to saying that if an observation at hand is (only) 5% or less likely to have been generated by chance, then it will be accepted as significant. In this example, the p-level (which is the actual probability of the observation being generated by chance) is lower than 5% (0.0421<0.05) and therefore a conclusion can be made that the observed outcome is significant.
An example of an outcome being significant could a drug improving patients's condition in a clinical study.
Answer:
1,100
Step-by-step explanation:
Since we know that 825 people are men, and that 75% of the people are men, we can write an equation to help us solve this, which is x times 0.75= 825, with x representing how many people work at the company. We must divide both sides by 0.75 to isolate the variable x and get our answer, which is 1,100 as x= 1,100 (825 divided by 0.75 equals 1,100).
