Answer:7/6
Step-by-step explanation:
divide both 35 & 30 by 5 since it’s their greatest common factor.
that would get u 7/6
Answer:
The slope will be:
slope = 0.3
Step-by-step explanation:
As we know that the slope of a certain line is basically the measure of its steepness.
Mathematically, the slope can be calculated as 'rise over run'.
In other words, the 'rise' is 'change in y', and 'run' is 'change in x'.
Given
The roof of the school has a rise = 3.6 meters = rise = change in y
The roof of the school has a run = 12 meters = run = change in x
So the slope will be:
slope = rise ÷ run
= 3.6 ÷ 12
= 0.3 ∵( 3.6 ÷ 12 = 0.3)
Therefore, the slope will be:
slope = 0.3
What are u asking ? I’m don’t get it
Angles B and C are both supplimentary angles with the numbers they are closest to. The sum of two supplimentary angles is always 180 degree. Therefore:
B + 45 = 180
B = 135
C + 105 = 180
C = 75
We now know two out of three of the angles for the inside of the triangle. The sum of the interior angles of a triangle is always 180. Therefore, we can solve for A.
A + 75 + 45 = 180
A = 60
Therefore A = 60, B = 135 and C = 75.
Answer:
A sample size of 474 is required.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of 
, and a confidence level of 
, we have the following confidence interval of proportions.
In which
z is the z-score that has a p-value of 
.
The margin of error is of:
Based on previous evidence, you believe the population proportion is approximately 73%.
This means that 
95% confidence level
So 
, z is the value of Z that has a p-value of 
, so 
.
How large of a sample size is required?
A sample size of n is required, and n is found when M = 0.04. So
Rounding up:
A sample size of 474 is required.
