If angle 4 is 52.7, what are the measures of angles 1,2, and 3? ​
shusha [124]

Answer:

  1. 127.3
  2. 52.7
  3. 127.3
  4. 52.7

Step-by-step explanation:

Since we know the angle measure of angle 4, we already know that angle 2 will have the same measure according to do the vertical angle theorem. Now to find angles 1 and 3, we can make an equation and solve for x (supplementary angles).

52.7 + x = 180

x = 127.3

Best of Luck!

A researcher studying public opinion of proposed Social Security changes obtains a simple random sample of 35 adult Americans an
Liula [17]

Answer:

Adult required in the case of “a” 28 and in the case of “b” the adult requirement is 19.

Step-by-step explanation:

(a) The percentage of adult that support the change is 20 percent.

Now calculate the number of adult required.

Given p = 0.20

Use the below condition:

np(1 – p) \geq 10 \\n \times 0.20 (1 – 0.20) = 10 \\n = 63 round off

Since 35 adults are already there so required adults are 63 -35 = 28

(b) The percentage of adult that support the change is 25 percent.

Now calculate the number of adult required.

Given p = 0.25

Use the below condition:

np(1 – p) \geq 10 \\n \times 0.25 (1 – 0.25) = 10 \\n = 54 (round off)

Since 35 adults are already there so required adults are 54 -35 = 19 .

What is thd solution for the equation 14.8=n-0.3
Nina [5.8K]
The given equation is:

14.8 = n - 0.3

Adding 0.3 to both sides, we get:

14.8 + 0.3 = n - 0.3 + 0.3
15.1 = n - 0
15.1 = n

Thus, the value of n for which the given equation is true is 15.1
