Answer: .03x + .06y ≤ 20
<u>Step-by-step explanation:</u>
Let x represent the number of minutes to the US and
let y represent the number of minutes to Brazil
and make sure their sum is not greater than $20
.03x + .06y ≤ 20
Answer:
x = 47
Step-by-step explanation:
3x - 2 + 41 = 180 {Supplementary}
3x + 39 = 180
3x = 180 - 39
3x = 141
x = 141/3
x = 47
Answer:
Rational
Step-by-step explanation:
You can write it as a ratio of a/b
Answer:
Null hypothesis
Alternative hypothesis
t = - 2.05
Degree of freedom df = 14
P-value = 0.0298
Decision rule: To reject if significance level ∝ is greater than P-value.
Conclusion: We reject at the level of significance ∝ = 0.1, thus there is sufficient evidence to conclude that the machine is underfilling the bags.
Step-by-step explanation:
Given that:
Population mean = 443
Sample size n = 15
Sample mean = 434
standard deviation = 17
Level of significance ∝ = 0.01
The null and the alternative hypothesis can be computed as:
Null hypothesis
Alternative hypothesis
The t-test statistics can be computed as :
t = - 2.05
Degree of freedom df = n - 1
Degree of freedom df = 15 - 1
Degree of freedom df = 14
From t distribution table; from the area in the lower tail to the left of t = -2.05 and for the degree of freedom df = 14, it is given by 0.0298
Thus, P-value = 0.0298
Decision rule: To reject if significance level ∝ is greater than P-value.
Conclusion: We reject at the level of significance ∝ = 0.1, thus there is sufficient evidence to conclude that the machine is underfilling the bags.
This equation follows the format y=mx+b, where m is the slope of the line and b is the y intercept. In this question, the slope of the line is -2 and the y-intercept is 5.
<em>The slope of the line is -2:</em> this means that each point is down 2 and to the right 1 of each other.
<em>The y-intercept is 5</em>: this means that the line crosses the y-axis at 5.
The picture shows the graphed line.
Hope this helps!
