The values of (x, y) are (-5, 1), if the equations x-5y=-10 and -x+y=6 are solved by elimination method.

Step-by-step explanation:

The given is,

                      x-5y=-10................................(1)

                    -x+y=6.....................................(2)

Step:1

           Equation (2) is multiplied by -1 ( Eqn (2) × -1 )

                      x-y=-6..................................(3)

Step:2

         Substrate the equation (1) and equation (3),

                                      x-5y=-10

                                        x-y=-6

          ( - )

         After the Subtraction equation becomes,

                   (x-x)+(-5y+y)=(-10+6)

                                (0)+(-4y)=(-4)

                                            -4y=-4

                                                 y=1

Step:3

           By using y value find value of x,

                                  x-5y=-10

                             x-(5)(1)=-10

                                           x=-10+5

                                           x=-5

Step:4

           Check for solution,

                                  -x+y=6

                              -(-5)+1=6

                                             6=6

           Both sides are equal so answer is corrected

Result:

         The values of (x, y) are (-5, 1), if the equations x-5y=-10 and -x+y=6 are solved by elimination method.

The probability of getting fewer than 3 correct answers is 0.1385

<h3>How calculate the probability of getting fewer than 3 correct answers?</h3>

This is a binomial problem with n = 13

Since we are dealing with a binomial probability distribution. We are going to use the binomial distribution formula for determining the probability of x successes:

P(x = r) = nCr . p^r  . q^n-r

total choices = 13 x 3 = 39

p = P(correct answer) = 13/39 =1/3

Given: n = 13, p = 1/3, q = 1- 1/3 = 2/3

Fewer than 3 correct answers mean less than 3 correct answers

P(x<3) = P(x = 0) + P(x=1) + P(x=2)

P(x<3) = (13C0 × (1/3)^0 × (2/3)^13-0) + (13C1 × (1/3)^1 × (2/3)^13-1 + (13C2 × (1/3)^2 × (2/3)^13-2)

         = 0.005138 + 0.0333 + 0.1001

         = 0.1385

Therefore, the probability that the person gets fewer than 3 correct answers is 0.1385

a patient is to take 2 4/5 tablespoons of medicine per day in 2 equally divided doses. how much medicine is to be taken in each
Ray Of Light [21]
Just divide 2 4/5 by 2:  

Convert 2 4/5 into the improper fraction 14/5, and then divide this result by 2:

7/5, or 1 2/5, tablespoons of medication, twice per day (total 2 4/5 tablespoons)

HELP PLEASE!! GIVE EXPLANATION! 15 PTS!!
Vinil7 [7]
So first, you need to separate the expression and numbers. For me, i would prefer putting the expressuon on the left hand side and numbers on the right hand side. this will make the solving more clearer and easier to solve.
10p+5=18p-62
10p-18p=-62-5
-8p =-67
p= 8.375

the answer should be
p= 8.375. but however it is not in the option.

Jan wants to protect the wooden box in question 4a by painting varnish on all of the outside surfaces, including the bottom. Wil
Dafna1 [17]

Answer:

As this question is incomplete, but we will try to solve this question by adding our own data to understand the concept of the problem.

Explanation is given below

Step-by-step explanation:

As this question is incomplete, but we will try to solve this question by adding our own data to understand the concept of the problem.

In order to answer this question we need to have the dimensions of the box.

Let's suppose there are 6 outside surfaces of the box and are equal in dimension including the bottom side which Jan wants to varnish.

So,

Let's suppose,

Surface area of the cube = 6a^{2}

Here, Surface area = 275 square inch

Surface area of the cube = 6a^{2} = 275 square inch

a^{2} = 275/6 = 45.833

a = \sqrt{45.833}

a = 6.77 inches

Now, for the amount of the varnish, we need the spreading rate of the varnish to be used on the box,

Let's suppose it is = 11 square incher per litre.

So,

Required Varnish = Surface area / Spreading rate

Required varnish = 275 / 11

Required varnish = 25 liters

If the 1 container of varnish contains 25 liters then it will be sufficient to protest the outside surfaces of the box.
