Just answer number 7 and 8
melamori03 [73]
We are given the equation:
F = 2.25+0.2(m-1)
where:
F is the fare
m is the number of miles.

In question 7, we are given that the fare (F) is equal to $6.05 and we need to get the number of miles. To do so, we will simply substitute with the fare in the given equation and solve for the number of miles (m) as follows:
F = 2.25 + 0.2(m-1)
6.05 = 2.25 + 0.2(m-1)
6.05-2.25 = 0.2(m-1)
3.8 = 0.2(m-1)
3.8/0.2 = m-1
19 = m-1
m = 19+1
m = 20 miles

Number 8 is exactly the same, but we will substitute F=7.65 and again solve for m

Answer:

The answer is "0.0764"

Step-by-step explanation:

Please find the complete question in the attached file.

\to \mu = \$ \ 4064\\\\\to \sigma = \$ \ 460 \\\\\to \sigma \bar{x} = \frac{\sigma}{\sqrt{n}}\\\\

        = \frac{460}{\sqrt{21}}\\\\ = \frac{460}{4.58257569}\\\\=100.3802

\to P(\bar{x}< \$ \ 3920) = \frac{P((\bar{x} - \mu \bar{x})}{\frac{\sigma \bar{x}

\to P(z < -1.43) = 0.0764 \\\\\to P(\bar{x}< \$ \ 3920) = 0.0764\\\\

If 3/4 is the dividend and -2/5 is the divisor then what is the quotient ?
Alexxx [7]

Answer:

\dfrac{-15}{8}

Step-by-step explanation:

<h3>Fraction division:</h3>

\sf \dfrac{3}{4} \ \div \dfrac{-2}{5}

 Use KCF method.

  • Keep the first fraction.
  • Change division to multiplication
  • Flip the second fraction.

       \sf \dfrac{3}{4} \ \div \dfrac{-2}{5}=\dfrac{3}{4}*\dfrac{-5}{2}

                      \sf = \dfrac{3*(-5)}{4*2}\\\\ =\dfrac{-15}{8}

FIRST ANSWER GET BRAINLEST
liraira [26]

Let's call x the price of a box of slime.

Gianna spent 4 × $58 for art supplies so 4(58) + 8x all together.  We have

392 ≤  4(58) + 8x ≤ 472

We can work with both inequalities at once.  4(58)=232 so we subtract that from all three sides.

160 ≤ 8x ≤ 240

Divide all three sides by 8, a positive number so the inequalities don't flip.

20 ≤ x ≤ 30

Answer: Least: $20, Most: $30
