Answer:

$1,236.25‬

Step-by-step explanation:

Since sales tax is 7.5% of the purchase, and since the pc costs 1,150, take 7.5% of 1,150, and add 1,150 and the new value together.

7.5 / 100 = 0.075

1150 * 0.075 = 86.25

1150 + 86.25 = 1236.25

Answer:

8x + 12y = 360

x-intercept = 45

y-intercept = 30

Slope = -3/4

Step-by-step explanation:

To begin, let's start with what we know

8 vans + 12 buses = 360 student

If we have vans as the variable x, having an unknown amount of students, and buses as y, also an unknown amount of students, also making 360 a flat number, we will get the equation

8x + 12y = 360

With this equation, we can find the y-intercepts and x-intercepts

The y-intercept can be found when x = 0, so let's substitute that in

8(0) + 12y = 360

   12y / 12 = 360 / 12

             y  = 30

The x-intercept can be found when y = 0, so let's substitute that in

8x + 12(0) = 360

8x/8          = 360/8

x                = 45

So, the x-intercept is 45 and the y-intercept is 30.

Next, let's find the slope. We can solve this easily by isolating y and finding the coefficient of x

8x + 12y = 360

-8x                    -8x

       12y = 360 - 8x  

12y / 12 = (360 - 8x) / 12

          y  = 30 - 3/4x

The coefficient of x is -3/4, so the slope will be -3/4

ddd [48]

Answer: 0.8926

Step-by-step explanation:

Given : A shipment of 50 inexpensive digital​ watches, including 10 that are​ defective.

The probability that a digital​ watch is defective : p=\dfrac{10}{50}=0.2

Sample size : n=10

Also, they reject the whole shipment if 1 or more in the sample are found defective.

Using the binomial probability formula :

P(x)=^nC_xp^x(1-p)^{n-x}

Let x be the random variable that represents the number of defective watches.

The probability that the shipment will be​ rejected :-

P(x\geq1)=1-P(0)\\\\=1-^{10}C_0(0.2)^0(0.8)^{10}\\\\=1-(0.8)^{10}=0.8926258176\approx0.8926

Hence, the probability that the shipment will be​ rejected = 0.8926
