Answer:

Step-by-step explanation:
x - number of adults
y - number of campers
<em>The room for 200 people</em>: x + y ≤ 200
<em>Each adult costs $4, and each camper costs $3</em>: 4x and 3y
<em>A maximum budget of $750</em>: 4x + 3y ≤ 750
Answer:
Therefore the value of tangent of ∠
is
°.
Step-by-step explanation:
Given that,
In Δ
, ∠
°,
and 
and we have to find the value of tangent of ∠
Diagram of the given triangle is shown below:
Now,
Δ
is a right angle triangle, so we can use all the trigonometric ratio.


= 
tangent of ∠
=
= 
= 
= 
∴∠
= 
=
° ≅
°
Therefore the value of tangent of ∠
is
°.
Answer:
Step-by-step explanation:
Using the alternative hypothesis (µ < µ0),
To find the p-value with test statistic -1.25 and assuming a standard level of significance of 0.05, using a p value calculator, the p-value is 0.1057 which is great that 0.05. Thus, the results is not significant.
Using the p value calculation.
1. Check the left tailed z table as the test statistic is negative,
2. Then find the probabilitythat z is greater than your test statistic (look up your test statistic on the z-table- the value under 1.2 and 0.05 which is 0.8944
3. Then, find its corresponding probability, and subtract it from 1 to get your p-value- 1-0.8944 = 0.1056.
