In the given figure, The marked angles forms a pair of co - interior angles [ because lines l and m are parallel ]
therefore,
Hence, the value of x is ~ 7
Answer:
Step-by-step explanation:
did u ever hear of the FOIL method ?
First, outside, inside, last
(5x + 2)(x + 1)
FIRST: multiply the first terms in each set : 5x * x = 5x^2
OUTSIDE: multiply outside terms in each set : 5x * 1 = 5x
INSIDE:multiply inside terms in each set: 2 * x = 2x
LAST: multiply last terms in each set: 2 * 1 = 2
so we now have : 5x^2 + 5x + 2x + 2....combine like terms
5x^2 + 7x + 2 <== ur answer
Answer:
angle x is 130 degrees
Step-by-step explanation:
Recall that the addition of all central angles of the full circle should add up to . There are two angles that are explicitly given: MON = , and POR = . The other piece of information is that the arc from M to R is 4 times the length of the smaller arc From N to M, and therefore, their angles should keep the same proportion. That is: angle MOR should be 4 times angle MON, which in math terms will be: MOR = 4 x , then MOR = .
Now, since the addition of all angles should total , we can find what angle "x" measures:
Answer:
This statistic is misleading because Howard surveys only his department, and not membes of all the departments that the company has.
Step-by-step explanation:
This is a common statistics practice, when we want to study something from a population, we find a sample of this population.
However, the sample has to be representative
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So i ask, lets say, 1000 randomly selected Buffalo residents wheter they are Buffalo Bills fans, and expand this to the entire population of New York State residents. This is not representative of all New York State residents, just Buffalo residents.
In this problem, we have that:
Howard wants to know the proportion of employees of a company who use the company's healthcare. He asks only his department. However, a company as multiple departments, which leads to the statistics found in Howard's survey being misleading.
