Answer:
The confidence interval is (0.1008, 0.1792)
Step-by-step explanation:
According to the question, the data provided is as follows
p′=0.14
sampling standard deviation of σp′= 0.02
Based on the above information
The computation of the 95% confidence interval for the true or correct proportion is
Here we apply the z value of 95% confidence interval i.e. 1.96
Now the confidence interval is
[tex]= (pcap - z\times sigma, pcap + z\times sigma)\\\\= (0.14 - 1.96\times 0.02, 0.14 + 1.96\times 0.02)\\\\= (0.1008, 0.1792)[/tex]

After measuring the foot size of 15 of his biology classmates, Laquon finds the average value and claims that it is the
average foot size of all 1,200 students in his high school.
What is most likely a problem with Laquon's conclusion?
A) He should have found the mode instead of the average.
B) He should have used shoe size instead of measuring feet.
C) The amount of data he collected was inadequate.
D) The data he collected was measured incorrectly.
Answer: C. The amount of data collected was inadequate:
Step-by-step explanation: Interviewing 15 students out of 1,200 does not show an accurate result, as he should have interviewed more students. Also, just took the quiz.

If fx = 3x over 5 +3 which of the following is the inverse
Answer:
f^(-1)(x) = -3x/(3x-3)
Step-by-step explanation:
1) replace f(x) by y
● y = 3x/(5x+3)
2) exchange x and y
● y = 3x/(5x+3)
● x = 3y / (3y +3)
3) solve for y
● x = 3y / (3y +3)
● x (3y +3) = 3y
● 3xy + 3x = 3y
● 3xy - 3y = -3x
● y (3x - 3) = -3x
● y = -3x /(3x-3)
4) replace y with f^(-1)(x)
● y = -3x/(3x-3)
● f^(-1)(x) = -3x/(3x-3)

What is the value of y in the equation 6.4x + 2.8y = 44.4, when x = 3?
Answer:
y = 9
Step-by-step explanation:
Given
6.4x + 2.8y = 44.4 ← substitute x = 3 into the expression
6.4(3) + 2.8y = 44.4
19.2 + 2.8y = 44.4 ( subtract 19.2 from both sides )
2.8y = 25.2 ( divide both sides by 2.8 )
y = 9

A box contains four tiles 1,4,5 and 8 as shown. Kelly chooses one time places it back in the box then chooses a second tile. What is the probability that the sum of the two chosen tiles is greater than 7?
Answer:
the answer to that question is 11/16
Using the probability principle, the probability of picking two tiles which sums above 7 is 11/16.
Recall :
Probability = required outcome / Total possible outcomesThe only way to choose two tiles which sums up to a number greater than 7 would be :
(1,8), (8, 1), (4, 5), (5,4), (4, 8), (8,4), (5,8), (8,5), {4, 4}, {5, 5}, {8, 8}Since selection is performed with replacement ;
Total possible outcome = sample size = 4² = 16The probability of choosing two tiles whose sum is greater than 7 ;
11/16 =Hence, probability of choosing tiles with a sum greater than 7 is 11/16
Therefore, the probability of picking two tiles which sums above 7 is 11/16.

Help please!!!!!!!!:(
Answer:
Step-by-step explanation:
As seen from the first given equation: x + 1/x = 2
If we think of x as x/1 instead then we get:
x/1 + 1/x = 2.
To combine the fractions we multiply the top and bottom of the first one (x/1) by x to get x^2/x so both have the same denominator so we can combine them which gives us:
(x^2+1)/x=2
Move x to the other side and we get:
x^2+1=2x
Move it back and we get a quadratic equation of
x^2 - 2x + 1
This factors into (x-1)(x-1) meaning x=1
For all the other equations they are equal because x=1.
1 to the power of anything is still one so each of the equations below will result in: 1+1/1 which is 2.
Therefore all of them are equal.

If x = 1, then 3*1 = 3 which when modded with 5, we get 3 as a remainder. In other words, 3/5 = 0 remainder 3. We don't use the quotient at all when it comes to modular arithmetic. All we care about is the remainder.
If x = 2, then 3*2 = 6 which leads to remainder 1 when we divide by 5. Therefore, 3x = 1 (mod 5) when x = 2.
If x = 3, then 3*3 = 9 = 4 (mod 5) because 9/5 = 1 remainder 4.
So 3x = 4 (mod 5) when x = 3.
The final answer is C) 3We don't need to check D since x = 3 is a solution and it's smaller than x = 4.
If you wanted to check x = 4, then 3*4 = 12 = 2 (mod 5) because 12/5 yields a remainder of 2.

Answer:
5x + 6y = -10
Step-by-step explanation:
(-2, 0) and (-8, 5)
m = (y₂ - y₁) / (x₂ - x₁)
m = (5 - 0) / (-8 -(-2)
m = 5 / (-8+2)
m = -5/6
y = mx + b
(-8, 5)
5 = -5/6(-8) + b
5 = 40/6 + b
b = 5 - 40/6
b = -5/3
y = mx + b
y = -5/6x - 5/3 *6
6y = -5x -5(2)
6y = -5x - 10
5x + 6y = -10

Rewrite the quadratic equation in the form y=a(x - h)^2 + k
y= 4x^2 -16x + 64
Answer:
y = 4(x - 2)² + 48
Step-by-step explanation:
Given
y = 4x² - 16x + 64
Using the method of competing the square
Factor out 4 from 4x² - 16x
y = 4(x² - 4x) + 64
add/ subtract ( half the coefficient of the x- term)² to x² - 4x
y = 4(x² + 2(- 2)x + 4 - 4 ) + 64
= 4(x - 2)² - 16 + 64
= 4(x - 2)² + 48
y = 4(x - 2)² + 48
