======================================================

Explanation:

The event space is the set of outcomes we want to happen.

The event space is {5, 6, 7, 8, 9, 10, 11} which consists of getting a value greater than 4. There are 7 items in this event space. Let A = 7.

The sample space consists of all possible outcomes. The sample space is {1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11} and there are 11 items in the sample space. Let B = 11.

Divide the values of A and B to get the answer we're after

A/B = 7/11

This is the probability of selecting a value greater than 4.

Answer:

$608

Step-by-step explanation:

Well first you have to see that there is 4 people going ari and his 3 brothers. Then I multiplied 4 people times 18 dollars a week. I got 72. After that I multiplied 72 dollars by 4 because of the 4 weeks they will be collecting money and I got 288. Lastly I added the 288$ to the 320 dollars they already saved and in total I got $608.

$608

40cm

Step-by-step explanation:

if the area is 100 then you have to do the square root of 100 which is 10.

each side is 10.

10 x 4 because 4 equal sides

40

Answer:

The required equations are:

C) x + y = 18

D) y = 3x - 2

Step-by-step explanation:

Let x be the length of shorter piece and y be the length of larger piece

It is given that the total length is 18 ft which gives us our first equation

[tex]x+y = 18[/tex]

Now it is also given that

"3 times the length of the shorter piece (x)"

[tex]3x[/tex]

"2 ft less than 3 times the length of the shorter piece (x)"

[tex]3x-2[/tex]

Second equation will be:

[tex]y = 3x-2[/tex]

Hence, the required equations are:

C) x + y = 18

D) y = 3x - 2

Solution :

Sampling may be defined as the technique of selecting the individual members or the subset of the population to make a statistical inferences and estimates the characteristics of the entire population.

There are several sampling methods. This includes : Systematic sampling, clustered sampling, stratified sampling, quota sampling, judgement sampling, random sampling, convenience sampling and many more.

In the context, the sampling methods for each of the descriptions are :

a). The researcher use computer program to randomly choose a sample of 30 mice of the 1000 mice for using her study

   --- Simple Random

b). The researcher chose the 1st 30 mice as she can reach the door to the mouse room

   --- Convenience sampling

c). The mice those whose are kept in the cages on 10 various shelves in mouse room. The researcher or the experimenter chose the three mice from each shelve.

  ---- Stratified sampling

d). Each of the cage have 5 mice and the researcher randomly chooses 6 cages for her study

----- Cluster sampling

e). The researcher generates the list of the identification numbers which has been sorted from the smallest to the largest. The researcher randomly picks 1 mouse form the list and selects every 4 mouse until the researcher has 30 mice.

 ---- Systematic sampling

Step-by-step explanation:

Answer:

The polynomial equation that cannot be solved using the quadratic formula: Option2: [tex]x^2-2x^3-5=0[/tex]

Step-by-step explanation:

First of all we have to learn what a quadratic polynomial is.

A polynomial or equation of degree 2 is called a quadratic equation. Quadratic formula is used to solve quadratic equations.

The quadratic equation is of the form:

[tex]ax^2+bx+c = 0[/tex]

From the given options, only option 2 doesn't have degree 2 so it is not a quadratic polynomial.

Hence,

The polynomial equation that cannot be solved using the quadratic formula: Option2: [tex]x^2-2x^3-5=0[/tex]

Answer:

he is 23 miles northeast from this starting spot

Step-by-step explanation:

ok so you start with the directions and notice they are different but this equation worked in our favor because the directions are north and east then all you do is add 8 + 15 and you get 23 so its 23 miles northeast from starting position

Answer:

1 unit = 3 inches

Step-by-step explanation:

We are given that 4 units = 12 inches.

This can be rewritten as 4x = 12

Then to solve for x, you divide 4 on both sides

so x = 12/4

x = 3

Let me know if you have any questions

Answer:

Step-by-step explanation:

4 units = 12 inches

1 unit = 12 ÷ 4 = 3 inches

Hope This Helped Have a Good Day! :)

Step-by-step explanation:

Answer: See explanation

Step-by-step explanation:

3.) 140 and its supplementary angle form a straight line, basically, they sum up to 180°. That angle is y

y + 140 = 180

Subtract both sides by 140

y = 40°

Seems both angles are congruent since they have the same label.

y + x + x = 180°

40 + 2x = 180

Subtract both sides by 40

2x = 140

Divide both sides by 2

x = 70°

4.) The missing angle = y

2x - 14 + 3x + 2 + y = 180

5x - 12 + y = 180

Subtract 5x from both sides

-12 + y = - 5x + 180

Add 12 to both sides

y = -5x + 180 + 12

y = -5x + 192

3x + 2 + 2x - 14 - 5x + 192 = 180

3x + 2x - 5x + 2 - 14 + 192 = 180

0 + 180 = 180

180 = 180

That's correct I guess.

5.) Missing angle = y

2x + 8 + 5x + y = 180

7x + 8 + y = 180

Subtract 7x from both sides

8 + y = -7x + 180

Subtract 8 from both sides

y = -7x + 180 - 8

y = -7x + 172

2x + 8 + 5x - 7x + 172

2x + 5x - 7x + 8 + 172 = 180

0 + 180 = 180

180 = 180

I.. think that's correct..?

6.) Missing angle = y

134 + y = 180

Subtract 134 from both sides

y = 46°

x + 46 + 22 = 180

x + 68 = 180

Subtract 68 from both sides

x = 112°

#4 and #5 were honestly sooo confusing. I just did whatever but I hope this is correct lol.

Answer:

Says your in college-

Step-by-step explanation:

Answer:

m∠3 = 143°

Step-by-step explanation:

m∠1 = 53°

m∠2 = 180 - (90 + 53) = 37°

m∠3 = 180 - 37 = 143°

Answer:

143

Step-by-step explanation:

solution:

angle 1 = 53°

angle D = 90°

angle 3 = angle 1+ angle D [sum of two]

= 53°+90° [interior angle is equal ]

=143° [to an exterior angle]

Answer:

the linear function is y= -x+9
