What is the value of x?Please help ✨

Mathematics
1 answer:
mestny [16]2 years ago
6 0

To solve this problem, we must remember that vertical angles (angles that are across from one another as <TRS and <VRW are above) have the same measure, they are equivalent. This means that we can set up an equation that sets the measures of these two angles equal to one another, as shown below:

x + 40 = 3x

To solve this equation, we will begin by subtracting x from both sides of the equation so that all of the variable terms are on the right side of the equation.

40 = 2x

Next, we should divide both sides of the equation by 2 so that we can get the variable x alone on the right side of the equation and cancel out its coefficient of 2.

x = 20

Therefore, your answer is x=20 (the first option listed).

Hope this helps!

Which of the following is not true about the standard error of a statistic?
aniked [119]

Answer:

Only option d is not true

Step-by-step explanation:

Given are four statements about standard errors and we have to find which is not true.

A. The standard error measures, roughly, the average difference between the statistic and the population parameter.

-- True because population parameter is mean and the statistic are the items.  Hence the differences average would be std error.

B. The standard error is the estimated standard deviation of the sampling distribution for the statistic.

-- True the sample statistic follows a distribution with standard error as std deviation

C. The standard error can never be a negative number. -- True because we consider only positive square root of variance as std error

D. The standard error increases as the sample size(s) increases

-- False.  Std error is inversely proportional to square root of n.  So when n  decreases std error increases

18. Find two numbers whose L.C.M is 3965 and G.C.F is 61​
Artist 52 [7]

Answer:

305 and 793

Step-by-step explanation:

LCM * HCF = product

3965 * 61 = 241,865 = 5*13*61*61

HCF = 61 so

61*5 = 305

61 * 13 = 793
