Answer:
no solution
Step-by-step explanation:
Given
2(x + 4) - 6 = 2(x - 8) + 1 ← distribute and simplify both sides
2x + 8 - 6 = 2x - 16 + 1
2x + 2 = 2x - 15 ( subtract 2 from both sides )
2x = 2x - 17 ( subtract 2x from both sides )
0 = - 17 ← not possible
This indicates the equation has no solution

If z is the complex number then IzI = 5 represents the equation of the circle.
What is a circle?A circle is a closed, two-dimensional object where every point in the plane is equally spaced from a central point. The line of reflection symmetry is formed by all lines that traverse the circle.
And the general formula of the circle,
(x – h)²+ (y - k)² = r²,
where (h, k) is the center and r is the radius of the circle.
Given:
The equation of the circle.
IzI = 5.
The set of all complex numbers with a given modulus (such as 5) always has the shape of a circle.
And the modulus represents the radius of the circle.
Therefore, the modulus represents the radius of the circle.

can someone help me solve for x and show the work please
Answer:
D. -10
Step-by-step explanation:
The sum of a triangle = 180°, therefore,
64° + 63° + x + 63 = 180°
Add like terms
x + 190° = 180°
Subtract 190 from each side
x + 190 - 190 = 180 - 190
x = -10

Tara bought a silver coat rack originally priced at $375 but on sale for 20% off. After 12% sales tax, what was the total cost?
Answer:
$336
Step-by-step explanation:
1 - 20% = .8
1 * 12% = 1.12
375 * .8 * 1.12 = 336
The total cost was of $336.
--------------
This question is solved using percentages/proportions.
The original price is of $375.On sale for 20% off, which means that you pay 1 - 0.2 = 0.8 of the price.Sales tax of 12%, which means that the cost is also multiplied by 1 + 0.12 = 1.12.Thus, the total cost will be given by:
[tex]C = 375 \times 0.8 \times 1.12 = 336[/tex]
The total cost was of $336.

which choice is equivalent to the product below when x>/0
√2x^2 ·√4x
the answer is: 2x sqrt 2x
The expression √(2x²) · √(4x) is equivalent to the expression 2x√2x. Then the correct option is D.
What is an equivalent expression?The equivalent is the expressions that are in different forms but are equal to the same value.
The expressions are given below.
√(2x²) and √(4x)
Then the product of the expressions √(2x²) and √(4x) will be
⇒ √(2x²) · √(4x)
The factor of 2x² will be
2x² = 2 · x · x
The factor of 4x will be
4x = 2 · 2 · x
Substitute in the expression, then the expression will be
⇒ √(2 · x · x) · √(2 · 2 · x)
We know that √x² = x and √4 = 2. Then the expression will be
⇒ x√2 · 2√x
⇒ 2x√2x
Thus, the expression √(2x²) · √(4x) is equivalent to the expression 2x√2x.
Then the correct option is D.

Many fast-food restaurants have soft drink dispensers with preset amounts, so that when the operator merely pushes a button for the desired rink the cup is automatically filled. This method apparently saves time and seems to increase worker productivity. A researcher randomly selects 9 workers from a restaurant with automatic dispensers and 9 works from a restaurant with manual dispensers. At a 1% significance level, use the Mann-Whitney U Test to test whether workers with automatic dispensers are significantly more productive.
Automatic (Group 1): 153, 128, 143, 110, 152, 168, 144, 137, 118
Manual (Group 2): 105, 118, 129, 114, 125, 117, 106, 92, 126
What is the alternative hypothesis for this study?
Worker productivity is higher with automatic dispensers.Automatic dispensers fill cups faster than manual dispensers. Worker productivity is lower with automatic dispensers.There is no difference in worker productivity between restaurants with automatic and manual dispensers.
What rank will be given to the observation value, 118 that is in both the automatic and manual groups? (Round answer to 1 decimal)
When rounding the U test statistic up to the next value, what is the p-value from the Mann Whitney Table of p-values? (Round to 4 decimal places)
What can be concluded from this study at a 1% significance level?
There is no difference in worker productivity between restaurants with automatic and manual dispensers.Worker productivity is higher with automatic dispensers. Automatic dispensers fill cups faster than manual dispensers.Worker productivity is lower with automatic dispensers.
Answer:
Alternative hypothesis is that Worker productivity is higher with automatic dispensers.
The Rank for Group1 is 115.5 and Group 2 is 55.5.
Conclusion is that Worker productivity is higher with automatic dispensers.
Step-by-step explanation:
The null and alternative hypotheses are
H0: Group1 ≤ Group2 against the claim
Ha: Group1 > Group2
Alternative hypothesis is that Worker productivity is higher with automatic dispensers.
Calculations:
Group1 Group2
Sample Mean x ` 139.22 114.67
Sample size n 9 9
Sample SD 18.21 11.937
Rank 115.5 55.5
U 10.5 70.5
The Rank for Group1 is 115.5 and Group 2 is 55.5.
1. H0 hypothesis
As p-value < alpha and Z lies in the critical region, H0 is rejected.
The randomly selected value of Group1's population is considered have greater productivity than the randomly selected value of Group2's population.
2. P-value
The p-value equals 0.0046.
3. Test statistics
Z= u-μ+c/σ
The critical region for one tailed test for z at 0.01 significance level is
z > 2.33.
The test statistic Z equals 2.6063, which lies in the critical region of acceptance z> 2.326
4. Conclusion
As the calculated test statistic lies in the critical region H0 is rejected and it is concluded that
Worker productivity is higher with automatic dispensers.
