Step-by-step explanation:
Here,
7x-6=5x+10 (as it has given already that alternate exterior angle are equal.
now, simplifying,
or,7x-5x = 10+6.
or, 2x=16
or, x=16/2
Therefore the value of x is 8.

Answer:
The 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without is (0.500, 0.562).
Step-by-step explanation:
The complete question is:
A random sample of 1014 adults in a certain large country was asked "Do you pretty much think televisions are a necessity or a luxury you could do without?" Of the 1014 adults surveyed, 538 indicated that televisions are a luxury they could do without.Construct and interpret a 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without.
Solution:
In a sample of 1014 adults, 538 indicated that televisions are a luxury they could do without.
Compute the sample proportion of adults who indicated that televisions are a luxury they could do without as follows:
The (1 - <em>α</em>)% confidence interval for population proportion is:
The critical value of <em>z</em> for 95% confidence interval is:
*use a <em>z</em>-table.
Compute the 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without as follows:
Thus, the 95% confidence interval for the population proportion of adults in the country who believe that televisions are a luxury they could do without is (0.500, 0.562).
Answer:
x =2
Step-by-step explanation:
(x+4) /3 = 2
Multiply each side by 3
(x+4) /3 *3= 2*3
x+4 = 6
Subtract 4
x+4-4 = 6-4
x =2
Answer:
O Prime
Step-by-step explanation:
x^2 - 7x - 10
What two numbers multiply to -10 and add to -7
There are no two number that multiply to -10 and add to -7
On substituting x= 9 in the above equation,
y= 9-5= 4
and, the y coordinate is also same i.e. 4
Yes.
It satisfies the equation.
