Answer:
x=20
Step-by-step explanation:
Complementary means =90 degrees, so with that being said, you need to write the equation as follows:
2x+10+x+20=90
Then add like terms:
3x+30=90
Subtract 30 from both sides (30 and 90)
3x=60
Divide both sides by 3
x=20
I hope this helps!!

11. There are 300 and 250 cows on Farms A and B respectively. How
many cows from Farm A must be transferred to Farm B so that the
number of cows on Farm B is four times the number of cows on
Farm A?
Answers
Answer:
I think it's twenty five
Answer:
190
Step-by-step explanation:
we want 1/5 on farm A and 4/5 of cows on farm B.
[tex] \frac{(300+250)}{5} = \frac{550}{5} = 110[/tex]
110 cows is 1/5. 550-110=440 and 440 is 4/5.
we want 110 cows on farm A and 440 on farm B.
So, there already is 250 cows on farm B and we need to move 440-250=190 cows from farm A to farm B.
And you can check that 4*110=440

Percentage:
The Latin word "per centum," which meaning "by the hundred," was the source of the English word "percentage." Fractions with a denominator of 100 are called percentages. In other words, it is a relationship where the value of the entire is always assumed to be 100.
What is percentages ?
A percentage is a ratio or fraction where the full value is always 100. Sam, for instance, would have received 30 out of a possible 100 points if he had received 30% on his arithmetic test. In ratio form, it is expressed as 30:100 and in fraction form as 30/100.
Calculation of Percentage:
Finding the percentage of a whole in terms of 100 is what percentage calculation refers to. A percentage can be found in one of two ways:
By using the unitary method.
By changing the denominator of the fraction to 100.
It should be noted that when the denominator is not a factor of 100, the second technique of percentage calculation is not applied. In these situations, we employ the unitary technique.

Suppose a population has a mean happiness score of 75 and a standard deviation of 15. Researcher A takes a random sample of 100 participants. Researcher B takes a random sample of 25 participants. Which researcher is more likely to get a sample mean of 80 or higher
Answers
Answer:
Researcher A is more likely to get a sample mean of 80 or higher
Step-by-step explanation:
The central limit theorem states that if the sample size increases the sampling distribution of the mean approaches normal distribution.The z score would be given by
z= x`- ux/ (σx/√n)
The sample standard deviation is given by 15 / √25 = 3 and 15 / √100 = 1.5
z=75-ux/3/5
Suppose z= 1.96
1.96 = 75 - ux /0.6
1.176- 75= -ux
ux = 73.824
Now Putting values for the second sample
z=75-ux/1.5/10
Suppose z= 1.96
1.96 = 75 - ux /0.15
0.2904- 75= -ux
ux = 74.706
From the above we see that the larger sample size would give a sample mean equal to the population mean .
