Step-by-step explanation:
Perimeter = 2L + 2W
42= 2L + 2(8)
26 = 2L
13 = L
Answer:
c) 4
Step-by-step explanation:
<u><em>The sum of two numbers is 14. The larger number minus three times the lesser number is -2</em></u>
<u><em /></u>
To solve this question, we need to write the statement mathematically;
Let the two numbers be x and y
"The sum of two numbers is 14" can be mathematically written as x+y = 14
and
"The larger number minus three times the lesser number is -2" can be mathematically written as x - 3y = -2
x + y = 14 ------------------(1)
x - 3y= -2 -------------------(2)
Subtract equation (2) from equation (1)
[x - x = 0 y - (-3y)=4y 14-(-2)=16]
4y = 16
To get the value of y divide both-side of the equation by 4
4y/4 = 16/4
y = 4
Substitute y=4 into equation (1)
x + y =14
x +4 =14
Subtract 4 from both-side of the equation
x + 4 -4 = 10]-4
x = 10
x=10 and y =4
Therefore the lesser number is 4
QUESTION:- DETERMINE THE X-INTERCEPT AND THE Y-INTERCEPT FOR THE GRAPH OF THE EQUATION.
EQUATION:- 2x - 3y + 36 = 0
STANDARD EQUATION:- y=mx+c
where
- m-> slope.
- c-> Y-INTERCEPT
- x&y are the coordinates.
SO GIVEN EQUATION:- 2x - 3y + 36 = 0
WE CAN SOLVE THIS TO CHANGE IN FORMAT OF STANDARD EQUATION
SO :-
Answer:
Step-by-step explanation:
Using normal distribution
z = (x - mean) / standard deviation
Nine percent of americans say they are well informed about politics in comparison to most people.
That means probability of success is p =9/100 = 0.09,
then probability of failure is
q = 1-p =1 -0.09= 0.91
n = number of sample = 200
x=(8% of 200) = 0.08×200 =16
mean = np = 200×0.09= 18
Standard deviation = npq = 200×0.09×0.91= 16.38
We are looking for the probability that less than 8% of the people sampled will answer yes to the question
8% of 200 = 16
P (x greater than 16) =P(x lesser than/equal to 15)
z = 15-18 /16.38 = -3/16.38
= -0.18
Looking at the normal distribution table
P(x greater than 16) = 0.5714
