Hello there!
Before we answer the question, we must solve the equation first.
4x + 5 = 10
4x = 10 - 5
4x = 5
x = 5/4
Therefore,
The equation has one solution!
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The Margin of error in this survey is 1%.
<h3>What is the margin of error?</h3>
The margin of error is a statistic that expresses how much random sampling error there is in a survey's results. The wider the margin of error, the less confident one should be that a poll result reflects the outcome of a population-wide survey.
The random sample of 2500 sports fans, out of which 61% prefer basketball over soccer, therefore, we can write n=2500 and p=0.61. Thus, the margin of error can be written as,

Hence, the Margin of error in this survey is 1%.

Answer:
c
Step-by-step explanation:
the probability isn't unavailable so it's not A. 0
and it isn't less than 0 because it is still "may occur"
and it is not one because it is still "unlikely"
so its C. close to 0
rs + st = rt Plug in the values
3x + 1 + 2x - 2 = 64 Combine like terms (1 and -2)
3x -1 + 2x = 64 Combine like terms (3x and 2x)
-1 + 5x = 64 Add 1 to both sides
5x = 65 Divide both sides by 5
x = 13
Answer:
27
Step-by-step explanation:
Let's call boys and girls 3x and x respectively. Since 3x + x = 36, x = 9. Boys = 3x = 3 * 9 = 27.
