Answer:

x = 34

Step-by-step explanation:

1/4(x - 2) + 4 = 12

Subtract 4 from both sides.

1/4(x - 2) = 8

Multiply both sides by 4.

x - 2 = 32

Add 2 to both sides.

x = 34

Step-by-step explanation:

This is just a complicated method to do ratios and proportions

use the given x and y values and the ratio will be determined by k.

The Vertex is at (3, 0)

The Axis of symmetry is; x = 3

The x-intercept is; x = 3

We are given the quadratic equation as;

y = -2(x - 3)²

Expanding this gives us;

y = -2(x² - 6x + 9)

y = -2x² + 12x - 18

x coordinate of vertex = -b/2a = -12/(2 * -2) = 3

y coordinate of vertex = f(3) = -2(3)² + 12(3) - 18 = 0

Vertex is at (3, 0)

Axis of symmetry is the x coordinate of vertex = -b/2a = -12/(2 * -2) = 3

x-intercepts is gotten by finding the roots which are; x = 3 and 3

Answer:

x = 0

Step-by-step explanation:

Given equation,

→ 2(3x - 1) + 2(4x + 5) = 8

Now the value of x will be,

→ 2(3x - 1) + 2(4x + 5) = 8

→ 6x - 2 + 8x + 10 = 8

→ 14x + 8 = 8

→ 14x = 8 - 8

→ x = 0/14

→ [ x = 0 ]

Hence, the value of x is 0.

The sum of the masses of earth and its moon is 6.07 * 10^24kg

Scientific values are values expressed in the form A * 10^n

where

A is any value between 1 and 10

n is any integer

Given the following

Mass of earth = 6 *10^24kg

Mass of moon. = 7 *10^22kg

Take the sum

Sum = 600 * 10^22 + 7 * 10^22

Sum = 607 * 10^22

Answer: D e acute

Step-by-step explanation:

Answer:

D. Fail to reject the null hypothesis. There is enough evidence to oppose the gaming company's claim.

Step-by-step explanation:

Let μ = mean time to complete a role-playing game.

The company claims that their role-playing games take over 65 hours to complete, so the hypotheses are:

H₀: μ = 65       H₁: μ > 65

Therefore, this is a one-tailed test.

The significance level is 1%, so α = 0.01.

Find the value of the test statistic (z):

[tex]\textsf{sample mean }\overline{x}=63,\quad \sigma=10, \quad n=300[/tex]

[tex]\implies z=\dfrac{\overline{x}-\mu}{\sigma / \sqrt{n}}=\dfrac{63-65}{10 / \sqrt{300}}=-2\sqrt{3}=-3.4641...[/tex]

Using the “Percentage Points of The Normal Distribution” table, the critical value is z = 2.3263 meaning the critical region is Z > 2.3263.

Since z = -3.4641... < 2.3263, the observed value of the test statistic lies outside the critical region.  Therefore, the result is not significant.

Conclusion

There is sufficient evidence at the 1% level of significance to fail to reject H₀ and to oppose the alternative hypothesis that the mean time to complete the role-playing game is more than 65 hours.

Answer:

A) Reject the null hypothesis. There is enough evidence to oppose the gaming company's claim.

Step-by-step explanation:

The test statistic needs to fall within the rejection regions that are above and below the critical z-score associated with a 1% level of significance in order to reject the null hypothesis. Otherwise, we will fail to reject the null hypothesis.

the absolute deviation for the man is 3 years more than the one for the woman.

We know that the absolute value function:

m(x) = |x - 44|

Represents the absolute deviation of man's age, in years.

This means that the average age of a man in that city is 44 years old, so if a man has 64 years, then the absolute deviation is given by:

m(64) = |64 - 44| = 20

The absolute deviation for a man of 64 years old living in this city is 20 years.

Similar for the case of women, the equation here is:

w(x) = |x - 47|

If a woman has 64 years old, then the absolute deviation is:

w(64) = |64 - 47| = 17

The absolute deviation is 17 years.

We can see that the absolute deviation for the man is 3 years more than the one for the woman.

The reflection transformation of the given diagram means that; W' X' is parallel to Z' Y'

Reflection over y-axis is a reflection or flip over the y-axis where the y-axis is the line of reflection used. The formula for this is: (x,y) →(−x,y) ( x , y ) → ( − x , y ) .

To reflect an equation over the y-axis, simply multiply the input variable by -1: y=f(x)→y=f(−x) y = f ( x ) → y = f ( − x )

Thus, looking at the given image and applying the transformation rule above, we can say that the reflection of parallelogram WXYZ across the y-axis would mean that W' X' is parallel to Z' Y'

The coordinates of the point 3/10 of the way between A and B are (-19/15, 1/5).

Let P be the point that is 3/10 of a way from A to B. This means that it divides P in the ratio 3:10 = AP/PB = 3/10.

To find the coordinates, use the internal division formula, which is given as:

x = (mx₂ + nx₁)/(m + n)

y = (my₂ + ny₁)/(m + n)

Where,

(x₁, y₁) = A(-3, -5)

(x₂, y₂) = B(12, 4)

m = 3 and n = 10.

Substitute the values to find the x and y coordinates of point P.

y = (3×4 + 10(-5))/(3 +10)

On solving;

y = -19/15

Solve for x coordinates;

y = (3(12) + 10(-3)/(3 +10)

on solving;

y = 1/5

Therefore, the coordinates of the point 3/10 a way from A and B is (-19/15, 1/5).

To establish whether findings from a sample may be extrapolated to the entire population, we use inferential statistics.

A population is the total group about which you want to reach conclusions. A sample is the specific group from which you will collect data. Always, the sample size is less than the whole population. The term "population" in research rarely refers to people. Using an office as an example, all of the employees would represent the Population, and all of the managers would represent the Sample. To create a comparison, picture your population as an ocean, and your sample as an aquarium.

Inferential statistics is a branch of statistics that uses data to draw inferences and generalizations about a certain situation or fact.
