Answer:

**Answer:**

y = -7/5x - 6.7

**Step-by-step **

**y = -7/5x + 6. A Line that is parallel will always have the same slope. The slope is m. m in this situation = -7/5x. A lines equation is y = mx + b. m = -7/5. y = -7/5x + b. Now to find b we can substitute the given point which goes through the new line, (2, -6). In this point x =2 and y = -6. Now substitute the x and y values into our equation. y = -7/5x + b is now -6 = -7/5(2) + b. -7/5(2) = -7/10. -6 = 7/10 + b. Subtract 7/10 from -6. Its -6 and 7/10 or -6.7 . -6.7 = b. b = -6.7. Now substitute the b value into the equation. y = -7/5x -6.7. **

Which value is needed to determine a confidence interval for a sample mean?

OA

the margin of error for the proportion

ов.

the population size

OC.

the sample proportion

OD

the standard error of the mean

The **value **needed to determine a **confidence **interval for a **sample **mean is the **standard **error of the **mean **option** (D) **is **correct**.

It is defined as the **sampling **distribution following an approximately **normal **distribution for known **standard **deviation.

The formula for finding the **confidence **interval for **population **standard **deviation **as follows:

Where s is the **standard **deviation.

n is the sample size.

are the **constant **based on the **Chi**-**Square **distribution table:

α is the significance level.

σ is the **confidence **interval for **population **standard deviation.

Calculating the **confidence **interval for population **standard **deviation:

We know **significance **level = 1 - confidence level

It is given that:

The value needed to determine a **confidence **interval for a sample mean is the standard error of the mean.

CI = X + Z(s/√n)

Here **CI **is the **confidence **interval

**Z **is the **confidence **level

**X **is the **sample **mean

Thus, the **value **needed to determine a **confidence **interval for a **sample **mean is the **standard **error of the **mean **option** (D) **is **correct**.

**Step-by-step explanation:**

trust me i got it right Plato

the object is 12 ft, what is the height of the object if the shadow is 18 ft?

**Answer:**

8 ft

**Step-by-step explanation:**

Use the **direct variation equation, y = kx,** where k is a constant.

Change the equation to fit the variables: **L = kH**

**Plug in the given length of the shadow and the height of the object, then solve for k:**

L = kH

27 = k(12)

2.25 = k

**So, the equation is L = 2.25H**

Then, **plug in 18 as L, and solve for H:**

L = 2.25H

18 = 2.25H

**8 = H**

So, when the shadow is 18 feet, **the height of the object is 8 ft**

Using the concept of direct **variation**, we find that the constant of variation is 2.25. Subsequent substitution in the equation reveals that the **object's** height when the shadow is 18ft is 8ft.

The question involves the concept of direct variation in mathematics. In direct variation, two quantities increase or decrease together to keep their ratio constant. This concept is given by the equation Y = kX, where Y and X are the quantities and k is a constant.

In our situation, the **length** of the shadow (L) varies directly with the object's height (H), i.e., L = kt. We are given that L=27ft when H=12ft, we can find the constant k by solving the **equation** 27ft = k * 12ft. This will get us k = 27ft/12ft = 2.25.

Now, we can determine the object's height if the shadow is 18ft. By substituting the values into the equation, we get 18ft = k * H. Substituting the value of k (2.25) will yield H = 18ft /2.25 = 8ft. Hence, the object's height when the **shadow** is 18ft is 8ft.

(5x2 + 2x + 11) − (7 + 4x − 2x2)

**Answer:**

*7x² - 2x + 4 *

**Step-by-step explanation:**

(5x² + 2x + 11) - (7 + 4x - 2x²) = 5x² + 2x + 11 - 7 - 4x + 2x² =

(5x² + 2x²) + (2x - 4x) + (11 - 7) = *7x² - 2x + 4*
