Answer:
x=36
Step-by-step explanation:
First rewrite equation then multiply each side by 36. 9x-36=4x+144.
then move the variable 9x-4x+36=144. Next subtract 9x and 4x ...5x=144+36.... 5x=180. Lastly you divide 180÷5 this your answer x=36
It's just an equation, the number you're looking for is X, and then turn the words into an solvable equation with respect to X.
7X + 3 = 39 - 2X
9X = 39 -3 = 36
X = 4
Answer:
3 and 4
Step-by-step explanation:
We apply 2 transformations here.
f(x) ----> f(x + a) - this is a shift of a units to the left.
f(x) ---- > f(x) + a - this is a shift of a units vertically up.
x - 1 ----> x + 2 shifts it 3 units to the left.
3 ---->5 shifts it 2 units up.
Complete Question
A certain university estimated that the proportion of students who prefer 2 day a week classes to 1 day a week classes was somewhere in the interval (0.451, 0.872) . If a 95% confidence interval was used, find the point estimate of the proportion and the margin of error
Answer:
The point estimate is
The margin of error is
Step-by-step explanation:
From the question we are that
The estimate of the proportion of students who prefer 2 day a week classes to 1 day a week classes is (0.451, 0.872)
Generally the point estimate is mathematically represented as
=>
Generally the margin of error is mathematically represented as
=>
Answer:
hypotenuse
Step-by-step explanation:
Remember that when using sin and cos functions, the hypotenuse is always included as the denominator of the equation EXCEPT when you're solving with tan, which is opposite/adjacent.
