Answer:

Rosa will go farther.

Step-by-step explanation:

1. Samy's travel distance.

3/4 of 20

3/4 * 20 = 15 gallons

15 miles for every gallon

15 * 15 = 225

Samy's travel distance is 225 mIles

2. Rosa travel distance.

13 gallons

19 miles for every gallon

19 * 13 = 247 mIles

Rosa's travel distance is 247 mIles.

labwork [276]

Answer:

1, 2, 2, 2, 3, 8, 9

Step-by-step explanation:

The following data represent the times in minutes required for 18 co-workers to commute to work

48 42 31 29 41 22 38 38 21 39 22 48 22 12 34 32 23 28

Rewrite this data in ascending order

12 21 22 22 22 23 28 29 31 32 34 38 38 39 41 42 48 48

Now, the stem-and-leaf plot is

$\begin{array}{cc}\text{Stem}&\text{Leaf}\\ \\1&2\\2&1,2,2,2,3,8,9\\3&1,2,4,8,8,9\\4&1,2,8,8\end{array}$

The second row represents the leaves for the given data points in the range 20 to 29 for this stem-and-leaf plot, so the answer is

1, 2, 2, 2, 3, 8, 9

Find the area of rectangle with sides 2 5/6 and 4 4/7

g100num [7]

<h3>Given :</h3>

Length = $\sf2\dfrac{5}{6}$ cm.
Breadth = $\sf4\dfrac{4}{7}$ cm.

The area of rectangle.

<h3>Solution :</h3>

Area of rectangle = Length × Breadth

$\sf=2\dfrac{5}{6}\times4\dfrac{4}{7}$

$\sf=\dfrac{17}{6}\times\dfrac{25}{7}$

$\sf=\dfrac{17\times25}{6\times7}$

$\sf=\dfrac{425}{42}$

<h3>Area of rectangle is 425/42 cm².</h3>

The answer is B. y = -1/5x +1/2.

EXPLANATION

First solve for the slope:
$m = \frac{y2 - y1}{x2 - x1} \\ m = \frac{0 - \frac{3}{5} }{ \frac{1}{2} - \frac{1}{5} } \\ m = - \frac{1}{5}$
After finding the slope, look for the linear equation with the same value of m (parallel equation).

A sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to

Archy [21]

Answer:

0.2916, 0.1488, 0.0319

Step-by-step explanation:

Given that a sign on the pumps at a gas station encourages customers to have their oil checked, and claims that one out of 10 cars needs to have oil added.

Since each trial is independent there is a constant probability for any random car to need oil is 0.10

Let X be the number of cars that need oil

A) Here X is BIN(4,0.1)

$P(X=1) = 4C1(0.1)(0.9)^3 \\= 0.2916$

B) Here X is Bin (8, 0.1)

$P(x=2) = 8C2 (0.1)^2 (0.9)^6\\\\=0.1488$

C) Here X is Bin (20,5)

$P(x=5) = 20C5 (0.1)^5 (0.9)^{15} \\=0.0319$
