Answer:

x= 1.6

y= - 1.6

Step-by-step explanation:

y = 1.5x - 4

y = -x

WE solve for x and y using substitution method

LEts plug in -x for y in the first equation

y = 1.5x - 4

-x = 1.5x - 4

Subtract 1.5x on both sides

-2.5x=- 4

Divide both sides by -2.5

x= 1.6

Now plug in 1.6 for x in y=-x

y= - 1.6

Alex777 [14]

Answer:

The gas cost for the Camry will be $ 150.

Step-by-step explanation:

Since in planning a Thanksgiving vacation, you want to rent a car for a week and travel the Pacific Highway from San Francisco to San Diego, and you want to return to San Francisco via Las Vegas, Death Valley, and Yosemite National Park, and this trip covers approximately 1,500 miles, and you plan to return the car with a full tank of gasoline and are considering two options advertised by Hertz:

Toyota Camry, 40 mpg highway, costs $ 448.27 plus taxes and fees, totaling $ 533.65.

Toyota Prius Hybrid, 49 mpg highway, costs $ 610.58 plus taxes and fees, totaling $ 772.88.

In both cases, you must purchase gasoline, which costs $ 4.00 per gallon in California.

To determine the total cost of gasoline for the Camry, the following calculation must be performed:

(1,500 / 40) x 4 = X

37.5 x 4 = X

150 = X

Therefore, the gas cost for the Camry will be $ 150.

Answer: the standard deviation is 2.4

Step-by-step explanation:

The formula for standard deviation is expressed as

s = √npq

Where

p = probability of success

q = probability of failure

n = number of samples

From the information given,

The probability of success, p is given as 0.2. It means that the probability of failure, q will be 1 - p = 1 - 0.2 = 0.8

There were 35 attempts. This means that total number of samples, n is 35

The standard deviation becomes

√35×0.2×0.8 = √5.6 = 2.366

Approximately 2.4
