Solve the proportion 20/3=?/6
Answer:
40
Step-by-step explanation:
3x2=6 so 20x2=40. It is a 6.66:1 ratio.
The value of the unknown number in the equation 20/3 = ?/6 is 40.
What is the value of the missing number?Given the equation in the question:
20/3 = ?/6
To solve the equation 20/3 = ?/6, first represent the missing number with x:
20/3 = x/6
Cross-multiply and solve for the unknown value.
x × 3 = 20 × 6
Multiply 3 and x:
3x = 20 × 6
Multiply 20 and 6:
3x = 120
Next, divide both sides by 3:
3x/3 = 120/3
x = 120/3
x = 40
Therefore, the value of x is 40.

Find the quotient

Which choice describes the value of m when -5(m + 1) ≤ 23?
1. m ≥ -28/5
2. m ≤ -28/5
3. m ≥ -18/5
4. m ≤ -18/5
Answer:
Number 1
Step-by-step explanation:
-5(m + 1) ≤ 23
Distribute
-5m - 5 ≤ 23
-5m ≤ 23 + 5
-5m ≤ 28
-m ≤ 28/5
Since we divide by a negative the ≤ flips to ≥
m ≥ -28/5

Order of operation with Integers
Answer:
8
Step-by-step explanation:
we have to follow PEDMAS.
what we have to do in each operation:
Parenthesis ~ 100 + 8 to the second power
Exponents ~ 10 to the 2nd power, 8 to the 2nd power, 2 to the 3rd power
Multiplication ~ none
Division ~ 10 to the 2nd power - (100 + 8 to the second power) divided by 2 to the 3rd power
Addition ~ 100 + 8 to the 2nd power
Subtraction ~ 10 to the 2nd power - (100+8 to the second power)
doing the work:
we start with P: but in what we have to do in the Parenthesis, there is an exponent and addition. we do the exponent first. 8 to the second power is 64. now we can add. 100 + 64 = 164.
E: we did the 2nd exponent, but we need the other 2 for later. 10 to the 2nd power is 100, and 2 to the 3rd power is 8.
we can skip M because there isn't any multiplication to do.
D: we have to do 10 to the 2nd power - (100 + 8 to the second power) first. 100-164= 64. now we can devide. 64 devided by 8 = 8
A: we already did the addition in the parenthesis part.
S: we already did the addition in the parenthesis part.

Applying the exterior angle of a triangle theorem, m<WUV = 36°
What is the Exterior Angle of a Triangle Theorem?The exterior angle of a triangle theorem states that the measure of the angle formed, when one side of a triangle is extended, is equal to the sum of the opposite interior angles of that triangle.
Applying the exterior angle of a triangle theorem:
m<WUV + m<UVW = m<VWX
Substitute
2x + 8 + 3x + 16 = 8x - 18
Add like terms
5x + 24 = 8x - 18
5x - 8x = -24 - 18
-3x = -42
-3x/-3 = -42/-3
x = 14
m<WUV = 2x + 8
Plug in the value of x
m<WUV = 2(14) + 8
m<WUV = 28 + 8
m<WUV = 36°
Therefore, applying the exterior angle of a triangle theorem, m<WUV = 36°

Find a 95% confidence interval for the true population proportion.
In a survey of 765 employees of a large company, 30% said that they had high job satisfaction.
Answer:
The 95% confidence interval for the true population proportion is (0.27, 0.33).
Step-by-step explanation:
The (1 - α)% confidence interval for population proportion of is:
[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
The information given is:
[tex]\hat p=0.30\\n=765\\\text{Confidence level}=95\%[/tex]
The critical value of z for 95% confidence level is, 1.96.
Compute the 95% confidence interval for the true population proportion as follows:
[tex]CI=\hat p \pm z_{\alpha/2}\cdot\sqrt{\frac{\hat p(1-\hat p)}{n}}[/tex]
[tex]=0.30\pm 1.96\times\sqrt{\frac{0.30(1-0.30)}{765}}\\\\=0.30\pm 0.0325\\\\=(0.2675, 0.3325)\\\\\approx (0.27, 0.33)[/tex]
Thus, the 95% confidence interval for the true population proportion is (0.27, 0.33).
