A sample of 8 new models of automobiles provides the following data on highway miles per gallon. Highway Miles Model Per Gallon 1 33.6 2 26.8 3 20.2 4 38.7 5 35.1 6 28.0 7 26.2 8 27.6 a. What is the point estimate for the average highway miles per gallon for all new models of autos? b. Determine the point estimate for the standard deviation of the population.

Pls help, and don’t give random answers just so you can have points.

Does sine inverse have an exponent? If not, why is there a negative one there? If so, why can't you just divide?

a model rocket is fired straight up from the ground. The heigth of the rocket (in feet) at any time T (in seconds) can be modeled by the equation h= -16t^2+ 128 when will the height of the rocket be 240feets from the ground.

**Answer:**

**Step-by-step explanation:**

hello :

the sequence is geometric because : (1/4)/(-1/8) = (-1/8)/(1/16)=-2 = r

the nth term is : An =A1 × r^(n-1)

a common ratio is : r and A1 the first term

in this exercice : r =2 A1 = 1/16

when : n =12 you have the 12rd term A12

A12 = 1/16 × 2^(12-1) = 1/16 × 2^(11)

10100 is the answer hope it helps you.

**Answer:**

The volume of sphere is 267.95 units³.

**Step-by-step explanation:**

**Given that the formula of volume of sphere is V = 4/3×π×r³ where r represents radius. Then, you have to substitute the values into the formula :**

V=4/3πr^3

= 4/3 x π x 4^3

= 268.08

= 85.33 π

~ 300 units ^3

= 4/3 x π x 4^3

= 268.08

= 85.33 π

~ 300 units ^3

-42v +33 <8v +91

Move all terms with V to the left side by subtracting 8V from both sides.

-50v +33 < 91

Now get the term with V all by itself by subtracting 33 from each side:

-50v<58

Solve for V by dividing both sides by -50 ( when dividing an inequality by a negative number you also need to reverse the direction of the inequality sign).

v >58/-50

Reduce the fraction and relocate the negative sign:

V >-29/25

Move all terms with V to the left side by subtracting 8V from both sides.

-50v +33 < 91

Now get the term with V all by itself by subtracting 33 from each side:

-50v<58

Solve for V by dividing both sides by -50 ( when dividing an inequality by a negative number you also need to reverse the direction of the inequality sign).

v >58/-50

Reduce the fraction and relocate the negative sign:

V >-29/25

The **number** of **seconds** it takes **light** to **travel** from **Sirius to Earth** is .

Given that, the speed of light is about 1.86×10^5 miles per second. The star Sirius is about 5.062×10^13 miles from Earth.

We need to find out how many seconds it takes light to travel from Sirius to Earth.

To determine the **power** or **exponent** of 10, let us understand how many places we need to move the **decimal poin**t after the **single-digit number**.

- If the given number is
**multiples**of**10**then the**decimal point**has to move to the**left**, and the power of 10 will be**positive**. - If the given number is smaller than 1, then the decimal point has to move to the
**right**, so the power of 10 will be**negative**.

Let the number of seconds it takes light to travel from Sirius to Earth be n seconds

Now, the proportion=

⇒

⇒

Therefore, the **number** of **seconds** it takes **light** to **travel** from **Sirius to Earth** is .

**Answer:**

2.72 × 10^8 seconds

**Step-by-step explanation:**

1. Organize the given information to help you create the equation:

- Light travels 1.86 × 10^5 miles per 1 second

- Light travels 5.062 × 10^13 miles per *n* seconds

- Need to solve for *n*

2. Set up the equation (Make sure that both numerators and both denominators match units, so the seconds are either both on top or both on bottom, NOT switched):

=

3. Cross multiply (Multiply the first fraction's numerator by the second's denominator, and vice versa. It doesn't matter what number is on which side of the = sign)

*n *× (1.86 × 10^5) = 5.062 × 10^13

4. Solve for *n* by isolating the variable and dividing.

=

*n* =

*n ***= 2.72 × 10^8** (Make sure to include the unit, seconds)
