Answer:

p = -3/2q = 9r = -5/2

Step-by-step explanation:

Put the given coordinates in the equation for the line and solve for the unknown.

  y = -2x +3

  (p, 6) ⇒ 6 = -2p +3   ⇒   p = -3/2

  (-3, q) ⇒ q = -2(-3) +3   ⇒   q = 9

  (r, 8) ⇒ 8 = -2r +3   ⇒   r = -5/2

The given composite shape has an area of (72,78,66,84) cm2 and a perimeter of (42,47,40,33) cm.

Answers

Answer:

78 cm²

42 cm

Step-by-step explanation:

To obtain the area of the shape given :

The figure is divide into three different rectanglular parts :

Recall, area of a rectangle = Length x width :

Rectangle 1 : 9* 6 = 54 cm²

Rectangle 2 = 6 * 2 = 12 cm²

Rectangle 3 = 4 * 3 = 12 cm²

Total area = (54 + 12 + 12). = 78 cm²

Perimeter = sun of the exterior sides of the shape

Perimeter = (9 + 8 + 3 + 4 + 3 + 6 + 3 + 6) = 42 cm

14e -10 = 6+6e

Subtract 6e from each side

14e-6e -10 = 6+6e-6e

If a concrete mix contains 1-1/2 cubic feet of gravel, 1/2 cubic foot of water,
1 cubic foot of cement, and 2 cubic feet of sand, what percentage of the mix is
sand?

Answers

Answer:

The correct answer is "50%".

Step-by-step explanation:

The given values are:

Gravel,

= [tex](1-\frac{1}{2} )[/tex]

Water,

= [tex]\frac{1}{2}[/tex]

Cement,

= 1

Sand,

= 2

Now,

The total mixture will be:

= [tex]Gravel+Water+Cement+Sand[/tex]

By substituting the values, we get

= [tex](1-\frac{1}{2} )+\frac{1}{2} +1+2[/tex]

= [tex]\frac{1}{2} +\frac{1}{2} +1+2[/tex]

= [tex]4 \ cubic \ feet[/tex]

hence,

The percentage of sand will be:

= [tex]\frac{Sand}{Total}\times 100[/tex]

= [tex]\frac{2}{4}\times 100[/tex]

= [tex]50[/tex]%

A university professor asked his class of 42 students when they had studied for his class the previous weekend. There responses were. please answer part a, b and c

Answers

ANSWERS:

a) 16 students

b) 25 students

c) 2 students

STEP BY STEP:

There are 42 students in total. This question can be solved by "Principal of Inclusion and Exclusion"

Question a)

The students that studied on Sunday in total with overlaps is 30. To figure out the students that ONLY studied on Sunday you need to first minus the overlaps in the combos:

the combos:

3, 10, 6, 2

Since the last combo included all of the other dates, we need to minus it:

1, 8, 4, 2

Now we can use the total of Sunday and minus the combos that includes Sunday:

30 - (4 + 2 + 8)  = 16 students

Question b)

To figure out all the students that only studied on ONE day, not 2 not 3, just one day. We need to figure out the students that studied for Saturday and Friday using the same method before for figuring out Sunday:

Friday: 9 - 4 - 1 -2 = 2 students

Saturday: 18 - 1 - 2- 8 = 7 students

and now add them all together: 2 + 7 + 16 = 25 students

That is the total number of students that studied on one day.

Question c)

Now for the numbers of students that didn't study... We can just use the total to minus everything else!

42 - (25 + 1 + 4 + 8 + 2) = 2 students!!!

And thats all done!  If you still don't get it, please ask!

Find the area of the triangle which the line 2x – 3y +6=0 forms with the coordinate axis.

Answers

2x-3y+6=0 has an x intercept of 2 and a y intercept of -3.

That means the 2 sides of the right triangle are 2 and -3

Area of triangle= 1/2×base×height

                         = 1/2×-3×2

                         =-3

∴ Area of the triangle=-3

The area of the asked triangle is 3 sq units.

What is area?

Area is defined as the total space taken up by a flat (2-D) surface or shape of an object.

Given that, a triangle is formed by the line 2x – 3y +6=0 and the coordinate axis.

When we plot the graph of the line, we get, y-intercept = 2 and x-intercept = -3

Hence, the height and base of the triangle will be 2 and 3 respectively.

Area of a triangle = 1/2 (base) (height)

Area = 1/2 (2)(3)

Area = 3

Hence, the area of the asked triangle is 3 sq units.

Household Size Probability 1 0.04 2 0.09 3 0.14 4 0.20 5 0.29 6 0.14 7 0.08 8 0.02 a. What is the probability that there are less than 5 members in a household in India

Answers

Given:

Probability distribution table is:

Household Size :   1            2          3           4          5         6         7          8

Probability          : 0.04     0.09     0.14     0.20     0.29    0.14    0.08   0.02

To find:

The probability that there are less than 5 members in a household in India.

Solution:

Let x be the number of members in a household. The probability that there are less than 5 members in a household in India is:

[tex]P(x<5)=P(x=1)+P(x=2)+P(x=3)+P(x=4)[/tex]

[tex]P(x<5)=0.04+0.09+0.14+0.20[/tex]

[tex]P(x<5)=0.47[/tex]

Therefore, the probability that there are less than 5 members in a household in India is 0.47.

The average electric bill for a small electric company is $72 for the month of April with a standard deviation of $6. If the amounts of the bills are normally distributed, find the probability that the mean of the bills for 15 randomly selected residents will be less than $75

Answers

Answer:

Hence the probability that the mean of their utility bills will be less than $75 = P(X < 75) is 0.9736.

Step-by-step explanation:

Now,  

Population mean electric bill, [tex]\mu =[/tex]  $72  

Population standard deviation, [tex]\sigma =[/tex]  $6  

Standard error of the mean[tex]= \sigma / \sqrt{n} = 6 / \sqrt{15} = 1.5492[/tex]

The probability that the mean of their utility bills will be less than $75 = P(X < 75)

= P[Z < (75 - 72) / 1.5492]

= P[Z < 1.9365]

= 0.9736 (Using Z table)

Given the functions below, find f(x) - g(x) f(x) = 3x^2 + 2x + 1 g(x) = x^2 - 6x + 3

Answers

Answer:

Here is your answer.....

Hope it helps....

The value of given function f(x) - g(x) is 2x² + 2x + 1.

What is function?A relation between a collection of inputs and outputs is known as a function. A function is, to put it simply, a relationship between inputs in which each input is connected to precisely one output. Each function has a range, codomain, and domain.The characteristic that every input is associated to exactly one output defines a function as a relationship between a set of inputs and a set of allowable outputs.

Given,

                  f(x) =3x² + 2x + 1

                  g(x) = x² - 6x + 3

f(x) - g(x) = ( 3x² + 2x + 1) - ( x²- 6x + 3)

              = 3x² + 2x +1 - x² + 6x - 3

              = 2x² +8x - 2

Therefore , the value of given function f(x) - g(x) is 2x² + 2x + 1.
