Answer: 59.342
Step-by-step explanation:
The chi-square critical values are used to find the confidence interval for σ.
Left critical value = [i.e. chi-square value from chi-square table corresponding to degree of freedom n-1 and significance level of ]
To find : left critical value for 95% confidence interval for σ with n = 41.
Significance level :
degree of freedom = 41-1=40
Now, the left critical value for 95% confidence interval for σ with n = 41 is the chi-square value corresponding to degree of freedom n-1 and
=59.342 [from chi-square table ]
Answer:
The boy's age is 8, the younger brother's age is 4.
- What we know is that the first brother has to be 8, because the equation given is x = y(younger brother) + 8
- Now we must solve the equation based off of this.
- Hmm. What would the product of twice the sum of the younger brother's age be?
- If we have already found out that the older brother's age is currently 8, we know that that 8 + 4 is 12, and in that case, the 2 must be the current age apart the brothers are, 2 years. And that would mean the younger brother is 4. Let's finish the equation.
To find the younger brother's age using the given values...
That said, everything matches up with the equation. The first brother is twice the age of his younger brother.
Answer:
Step-by-step explanation:
We just multiply the values on the edges like we are finding the area of a square, L * L = area.
4x * 5x = 20x^2
4x * 8 = 32x
3 * 8 = 24
3 * 5x = 15x
Next add the answers together
20x^2 + 47x + 24
- 47,158
Because 10-83 = -73 -73 times 646 = -47,158
