Gianna is 90 miles far away in 3 hours of driving.

She drove in total of 180 minutes.

The speed can be defined as the rate at which an object covers some distance. Speed can be measured as the distance traveled by a body in a given period of time. The SI unit of speed is m/s.

Given,

Gianna drives 5 miles in 10 minutes

Speed per minute = 5/10 = 0.5 miles/minute

Gianna drove in total for 3 hours

1 hour = 60 minutes

3 hours = 60 × 3 = 180 minutes

Distance Gianna drove in 180 minutes = speed per minute × time

                                                                = 0.5 × 180

                                                                = 90 miles

Hence, Gianna drove 90 miles in 3 hours, 180 minutes is total time she drove.

Answer:

$44

Step-by-step explanation:

Hello!

It said that 7 cameras cost $308, right?

If each camera costs the same, it means that 7 cameras with the same value equal $308.
If we use this in an equation, and if x is a variable we want to solve, it would be:

7x = 308.

If 7x = 308, it would be

308/7 =

44.

So, $44 is the answer.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Number of buses that has 63 people = 5

Number of buses that has 54 people = 4

The total number of people in all the buses.

= 5 x 63 + 4 x 54

= 315 + 216

= 531

For the 21% of a number is 27, the value of 7% of that number is 7.

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

We have to given that;

⇒ 21% of a number is 27

Let a number is = x

So, We can formulate;

⇒ 27% of x = 27

Solve for x as;

⇒ 27/100 × x = 27

⇒ 27x = 27 × 100

⇒ 27x = 2,700

⇒ x = 2,700 / 27

⇒ x = 100

So, 7% of 100 is,

⇒ 7% of 100

⇒ 7/100 × 100

⇒ 7

Answer:

  ∠AGC  or  ∠FGD

Step-by-step explanation:

∠AGF is part of two linear pairs. The other angle in the pair is supplementary to ∠AGF.

Point G is on line AD, so ∠FGD is a supplementary angle to ∠AGF.

Point G is on line FC, so ∠AGC is a supplementary angle to ∠AGF.

The answer is (a) MX + MY. Whether or not X and Y are independent, we cannot simplify (a) or (b) further.

The mean of X + Y is:

E(X + Y) = E(X) + E(Y)

So the answer is not (a) or (b).

(c) is incorrect because the formula given is only true if X and Y are independent, but no such assumption is given in the problem.

(d) is also incorrect because we cannot simply divide the means by the standard deviations to get the standard normal variables, especially when the variables X and Y have different means.

Therefore, the answer is (a) MX + MY.

Standard Deviation is a measure which shows how much variation (such as spread, dispersion, spread,) from the mean exists. The standard deviation indicates a “typical” deviation from the mean. It is a popular measure of variability because it returns to the original units of measure of the data set.

Answer:

Step-by-step explanation:

RA = 4 in, RB = 2 in

oil height in A = hA = 2 in

Find oil height in B = hB

volume of oil in A = VA = π*RA² * hA

equal amount means volume of oil in B VB = VA

But VB = π*RB² * hB

so π*RA² * hA = π*RB² * hB

then

hB = hA *(RA/RB)² = 2 * (4/2)² = 8 in

Answer:

\(\displaystyle{f(x)=3^x-5}\)

Step-by-step explanation:

Being translated up-down means that the value exists outside of x. Therefore, we can cancel B and C choice since those are horizontal (left-right) translation.

Our only choice is A and D. However, D is being translated up since it's +5. Thus, the only correct answer that a function is being translated down is:

\(\displaystyle{f(x)=3^x-5}\)

Answer:

The value is \(n = 188 \)

Step-by-step explanation:

From the question we are told that

    The margin of error is  \(E = 0.06\)

From the question we are told the confidence level is  90% , hence the level of significance is    

      \(\alpha = (100 - 90 ) \%\)

=>   \(\alpha = 0.10\)

Generally from the normal distribution table the critical value  of  \(\frac{\alpha }{2}\) is  

   \(Z_{\frac{\alpha }{2} } =  1.645\)

  Generally will assume that the sample proportion young adults in Louisville, Kentucky, who received help from their parents in buying a home is  \(\^ p = 0.5\)

Generally the sample size is mathematically represented as  

    \(n = [\frac{Z_{\frac{\alpha }{2} }}{E} ]^2 * \^ p (1 - \^ p ) \)

=>  \(n = [\frac{1.645}{0.06 } ]^2 * 0.5 (1 - 0.5 ) \)

=>  \(n = 188 \)

The equation of the ellipse is \(\frac{x^2}{49} + \frac{y^2}{65} = 1\)

The given parameters are:

The above means that:

c = 4 and

The semi-major axis, a = 7 i.e 14/2

Calculate b using

\(b = \sqrt{c^2 + a^2\)

So, we have:

\(b = \sqrt{4^2 + 7^2\)

\(b = \sqrt{65\)

Square both sides

\(b^2 = 65\)

The standard form of the ellipse is represented as:

\(\frac{x^2}{a^2} + \frac{y^2}{b^2} = 1\)

This gives

\(\frac{x^2}{7^2} + \frac{y^2}{65} = 1\)

Evaluate

\(\frac{x^2}{49} + \frac{y^2}{65} = 1\)

Hence, the equation of the ellipse is \(\frac{x^2}{49} + \frac{y^2}{65} = 1\)
