a) 1.5 milliliters, b) 0.67 milliliters
Step-by-step explanation:
100 ml vinegar mixes with 150 ml soy sauce
So, 1 ml vinegar mixes with (150/100) = 1.5 ml soy sauce.
Again,
150 ml soy sauce mixes with 100 ml vinegar
So, 1 ml soy sauce mixes with (100/150) = 0.67 ml vinegar.

Answer:
3.0Step-by-step explanation:
Sample standard deviation is found by steps below.
Find the mean:
μ = (9 + 15 + 13 + 9 + 15)/5 = 12.2Find deviations from the mean and their squares:
9 - 12.2 = - 3.2 ⇒ (-3.2)² = 10.2415 - 12.2 = 2.8 ⇒ 2.8² = 7.8413 - 12.2 = 0.8 ⇒ 0.8² = 0.649 - 12.2 = - 3.2 ⇒ (-3.2)² = 10.2415 - 12.2 = 2.8 ⇒ 2.8² = 7.84Sum the squares:
10.24*2 + 7.84*2 + 0.64 = 36.8Divide by N - 1 (N - number of samples):

Answers
Answer:
Step-by-step explanation:
5). 3x + y = 5 -------(1)
2x - y = 10 ---------(2)
By adding equation (1) and (2),
(3x + y) + (2x - y) = 5 + 10
5x = 15
x = 3
From equation (1),
3(3) + y = 5
y = -4
6). 4x + 3y = 13 -------(1)
x + y = 4 -------(2)
Multiply equation (2) by 3 and subtract it from equation (1)
(4x + 3y) - (3x + 3y) = 13 - 12
x = 1
From equation (2),
1 + y = 4
y = -3
7). x - 7y = 7 -----(1)
-3x + 21y = -21
-3(x - 7y) = -(3 × 7)
x - 7y = 7 -------(2)
Since, equation (1) and (2) are same, system of the equations will have infinitely many solutions.
8). x - 3y = 12
3y = x - 12
[tex]y=\frac{1}{3}x-4[/tex] --------(1)
3x - 9y = 18
3(x - 3y) = 3(6)
x - 3y = 6
3y = x - 6
[tex]y=\frac{1}{3}x-2[/tex] ----------(2)
Slopes of both the equations are same but the y-intercepts are different.
Therefore, both the lines are parallel and the system of equations will have no solution.

Answer:
length = 15 meters
Step-by-step explanation:
Volume of a pyramid is:
V = l*w (h/3)
We know that; Volume is 40, Width is 2, and Height is 4, therefore;
40 = l*2 (4/3)
40 = 2l (4/3)
(3/4) * 40 = 2L
30 = 2L
30/2 = L
15 = L
therefore the length = 15 meters

Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
A random sample of 432 voters revealed that 100 are in favor of a certain bond issue.
This means that [tex]n = 432, \pi = \frac{100}{432} = 0.231[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].

Answers
Answer:
μ > 21.21
Test statistic = 1.217
Kindly check explanation for more details
Step-by-step explanation:
The null hypothesis, H0 : μ = 21.21
Alternative hypothesis, H1 : μ > 21.21
The test statistic :
(xbar - μ) ÷ (s/sqrt(n))
(21.212 - 21.21) ÷ (0.01 / √2)
= 1.217
The critical value :
From the t distribution :, one tailed = 2.434
Decision region :
Reject H0 if test statistic > critical value
1.217 < 2.434 ; We fail to reject the null ` ; and conclude that there is not enough evidence to support the claim.

b. Margin of error: 0.009, confidence level: 99%; p and q unknown
c. Margin of error: 0.01; confidence level: 95%; from a prior study, p is estimated by the decimal equivalent of 52%.
Answers
Answer:
a. The minimum sample size required is of 60,025.
b. The minimum sample size required is of 20,465.
c. The minimum sample size required is 9,589.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the z-score that has a p-value of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is of:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
Question a:
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
p and q unknown means that we use [tex]\pi = 0.5[/tex], which is when the largest sample size is needed.
Margin of error: 0.004
We have to find n for which M = 0.004. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.004 = 1.96\sqrt{\frac{0.5*0.5}{n}}[/tex]
[tex]0.004\sqrt{n} = 1.96*0.5[/tex]
[tex]\sqrt{n} = \frac{1.96*0.5}{0.004}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96*0.5}{0.004})^2[/tex]
[tex]n = 60025[/tex]
The minimum sample size required is of 60,025.
b. Margin of error: 0.009, confidence level: 99%; p and q unknown
99% confidence level
So [tex]\alpha = 0.01[/tex], z is the value of Z that has a p-value of [tex]1 - \frac{0.01}{2} = 0.995[/tex], so [tex]Z = 2.575[/tex].
Margin of error: 0.009
We have to find n for which M = 0.009. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.009 = 2.575\sqrt{\frac{0.5*0.5}{n}}[/tex]
[tex]0.009\sqrt{n} = 2.575*0.5[/tex]
[tex]\sqrt{n} = \frac{2.575*0.5}{0.009}[/tex]
[tex](\sqrt{n})^2 = (\frac{2.575*0.5}{0.009})^2[/tex]
[tex]n = 20464.9[/tex]
Rounding up:
The minimum sample size required is of 20,465.
c. Margin of error: 0.01; confidence level: 95%; from a prior study, p is estimated by the decimal equivalent of 52%.
Here we have [tex]\pi = 0.52[/tex].
The minimum sample size is n for which M = 0.01. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.01 = 1.96\sqrt{\frac{0.52*0.48}{n}}[/tex]
[tex]0.01\sqrt{n} = 1.96\sqrt{0.52*0.48}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.52*0.48}}{0.01}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.52*0.48}}{0.01})^2[/tex]
[tex]n = 9588.6[/tex]
Rounding up:
The minimum sample size required is 9,589.

On multiplication of number x with 6 it will be 6x.12
On subtraction of 5 it will be 6x - 5
6x - 5 = 7
6x = 7 + 5
6x = 12
x = 12/6
x = 2
Answer:

Let the number be n
Multiply the number by 6 = 6n
Subtract 5 from the number , 6n - 5

Answers

Answer:
center: (1/2, 6)
radius: √5
Step-by-step explanation:
The standard form equation for a circle of radius r and center (h, k) is ...
(x -h)^2 +(y -k)^2 = r^2
When we compare this to the given equation:
(x -1/2)^2 +(y -6)^2 = 5
we see that h=1/2, k=6, and r^2=5.
The center is (h, k) = (1/2, 6); the radius is √5.

D+16/3=17 the steps?
1. D+16/3=17
Divide 16/3.
D+6 = 17
2. subtract 6 from both side.
D = 11.
STEP1:
d + 16
Simplify ——————
3
Equation at the end of step
1
:
(d + 16)
———————— - 17 = 0
3
STEP
2
:
Rewriting the whole as an Equivalent Fraction
2.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 3 as the denominator :
17 17 • 3
17 = —— = ——————
1 3
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
2.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
(d+16) - (17 • 3) d - 35
————————————————— = ——————
3 3
Equation at the end of step
2
:
d - 35
—————— = 0
3
STEP
3
:
When a fraction equals zero :
3.1 When a fraction equals zero ...
Where a fraction equals zero, its numerator, the part which is above the fraction line, must equal zero.
Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:
d-35
———— • 3 = 0 • 3
3
Now, on the left hand side, the 3 cancels out the denominator, while, on the right hand side, zero times anything is still zero.
The equation now takes the shape :
d-35 = 0
Solving a Single Variable Equation:
3.2 Solve : d-35 = 0
Add 35 to both sides of the equation :
d = 35
