Answer:
x = 12, y = 0
Step-by-step explanation:
Use elimination.
24y = 0
y = 0
Then plug back into the second equation.
2x + 9(0) = 24
2x = 24
x = 12
Plug back into the first equation to check.
Answer:
0.003
Step-by-step explanation:
P-value = The value of probability.
P value can be defined are the probability of a given test statistic ( which could be z score, t score, f score) that is can be less than, equal to or greater than a given null hypothesis.
In the above question, the test statistic we are given = z score.
z score = -2.73
To find the P- value, we can make use of a z table for normal distribution.
Hence, P(z = -2.73) = 0.0031667
Approximately to the nearest thousandth = 0.003
Answer:
Width of the garden box = 4 feet
Step-by-step explanation:
Given that:
Length of garden box = 22 feet
Let,
w be the width of garden box
It is also given that:
The length of a garden box is 6 feet longer than 4 times the width.
L = 4w + 6
Putting L = 22
22 = 4w + 6
22 - 6 = 4w
4w = 16
Dividing both sides by 4
Hence,
Width of the garden box = 4 feet
