Answer:
Infinite solutions
Step-by-step explanation:
3(2d-1)-2d=4(d-2)+5 | Given equation
6d - 3 - 2d = 4d - 8 + 5 | Distribute
4d - 3 = 4d - 3 | Combine like-terms
4d = 4d
Infinite solutions, the terms are equal.
Answer:
w=38m
Step-by-step explanation: w ∝ m
w = km
w = number of words
m= minutes
k = constant of proportionality = 28
Hence w=38m
Answer:
x+6
Step-by-step explanation:
Answer:
a) P(12≤χ²≤24)=0.690
b) k=35.85
c) Median=18.34
Step-by-step explanation:
<em>The question is incomplete: "Use the calculator provided to solve the following problems. Suppose that χ² follows a chi-square distribution with 19 degrees of freedom. Compute P(12≤χ²≤24) . Round your answer to at least three decimal places.</em>
<em>Suppose again that χ² follows a chi-square distribution with 19 degrees of freedom. Find k such that P(χ²>k)=0.025. Round your answer to at least two decimal places.</em>
<em>Find the median of the chi-square distribution with 19 degrees of freedom. Round your answer to at least two decimal places."</em>
Compute P(12≤χ²≤24)
Find k such that P(χ²>k)=0.025
The median of the chi-square is:
