300 ÷ 12.50 = 24 biros

Answer 2

Answer:

24

Step-by-step explanation:

It's a ratio problem

Let B is Biro and N naira

B   :      N

1    :     12.5

x    :      300

then x = 300 * (multply) 1 /12.5 = 24

Step-by-step explanation:

Valerie and Seth are measuring the outside walls of a house using two different instruments. They want to find the house's perimeter. Valeria measured the north and east sides while Seth measured the west and south sides. Their results are listed in the table.

Part A
Use decimal numbers to write an expression that represents the length of the walls that Valerie measured.

Part B
Now use decimal numbers to write an expression that represents the length of the wall that Seth measured.

Part C
Write an expression for the perimeter of the house. Use the work you completed in part A & B to guide you.

Part D
Simplify the expression from part C to find the perimeter of the house in feet.

Part E
Suppose that you evaluate the expression for Valerie's wall and the expression for Seth's wall separately. Then you add the two expressions together. Will you get the same answer that you arrived at in part D? Why or why not? Show your work to prove your case.​

PLEASE PLEASE PLEASE HELP I REALLY NEED HELP IN THIS WORK, THANK YOU.

Answers

Answer:

A)

Valerie measured 4 walls at 2 1/2 feet. In decimal form, each wall is 2.5 feet long. So, the total length of the 4 walls is (2.5 × 4) feet.

Valerie measured 3 walls at 21 1/4 feet. In decimal form, each wall is 21.25 feet long. So, the total length of the 3 walls is (21.25 × 3) feet.

Valerie measured 1 wall at 32 feet.

The expression that gives the total length of the walls that Valerie measured is (2.5 × 4) + (21.25 × 3) + 32.

B)

Seth measured 1 wall at 3.5 feet.

Seth measured 2 walls at 22.75 feet. So, the total length of the 2 walls is (22.75 × 2) feet.

Seth measured 1 wall at 58 feet.

The expression that gives the total length of the walls that Seth measured is 3.5 + (22.75 × 2) + 58.

C)

The total length of Valerie’s walls is (2.5 × 4) + (21.25 × 3) + 32.

The total length of Seth’s walls is 3.5 + (22.75 × 2) + 58.

To find the expression for the perimeter of the house, add Valerie’s expression to Seth’s:

(2.5 × 4) + (21.25 × 3) + 32 + 3.5 + (22.75 × 2) + 58.

D)

(2.5 × 4) + (21.25 × 3) + 32 + 3.5 + (22.75 × 2) + 58

= 10 + 63.75 + 32 + 3.5 + 45.5 + 58

= 212.75

The perimeter of the house is 212.75 feet.

E)

The total length of Valerie’s walls is 105.75 feet:

(2.5 × 4) + (21.25 × 3) + 32 = 10 + 63.75 + 32 = 105.75 feet.

The total length of Seth’s walls is 107 feet:

3.5 + (22.75 × 2) + 58 = 3.5 + 45.5 + 58 = 107 feet.

The sum of 105.75 feet and 107 feet is 212.75 feet. The Commutative Property allows me to add numbers in any order. This is why the answers in parts D and E match.

points did Clare score?
60

Answers

Answer:

90

Step-by-step explanation:

She scored 50% more so scored 1.5x tyler

1.5 * 60 = 90

Answer:

90

Step-by-step explanation:

so for this, all we have to do is add %50 of the first score to the second one, first lets find out what %50 of that score is

%50 of 60 = 30 (because %50 is half of something)

next, we add that new amount to the first score

60 + 30 = 90

so 90 is %50 more then 60, or 90 is %150 of 60

A random sample of 250 juniors majoring in psychology or communication at a large university is selected. These students are asked whether or not they are happy with their majors. Assume that none of these 250 students is majoring in both areas. There are a total of 100 majoring in psychology and only 80 of those majoring in psychology are happy while 35 students majoring in communication are unhappy.
If one student is selected at random from this group, find the probability that this student is:________
i. happy with the choice of major
ii. a psychology major
iii. a communication major given that the student is happy with the choice of major
iv. unhappy with the choice of major given that

Answers

Solution :

It is given that :

Number of students in a random sample majoring in communication or psychology at an university = 250

Total number of students majoring in psychology = 100

Number of students majoring in psychology  those who are happy = 80

So number of students majoring in psychology  those who are not happy = 20

Total number of students majoring in communication = 250 - 100 = 150

Number of students majoring in communication  those who are happy = 115

So number of students majoring in psychology  those who are not happy = 35

a). Probability of the students happy with their major choices are

    [tex]$=\frac{80+115}{250}$[/tex]

    = 0.78

b). Psychology major [tex]$=\frac{80+20}{250}$[/tex]

                                   = 0.4

c). Probability of the students who are happy with the communication as the choice of major = [tex]$\frac{115}{250}$[/tex] = 0.46

d). Students unhappy with their choice of major given that the student is psychology major = [tex]$\frac{20}{250}$[/tex]  =  0.018

a) Probability of the students happy with their major choices is 0.78.

b) Probability of Psychology major is 0.4

c) Probability of the students who are happy with the communication as the choice of major is 0.46.

d) Students unhappy with their choice of major given that the student is psychology major is 0.018

Given:

Number of students in a random sample majoring in communication or psychology at an university = 250

Total number of students majoring in psychology = 100

Number of students majoring in psychology  those who are happy = 80

So, number of students majoring in psychology those who are not happy = 20

Total number of students majoring in communication = 250 - 100 = 150

Number of students majoring in communication  those who are happy = 115

So, number of students majoring in psychology  those who are not happy = 35

a). Probability of the students happy with their major choices are

[tex]=\frac{80+115}{250} =0.78[/tex]

b). Psychology major

[tex]\frac{80+20}{250} =0.4[/tex]

c). Probability of the students who are happy with the communication as the choice of major =[tex]\frac{115}{250} =0.46[/tex]

d). Students unhappy with their choice of major given that the student is psychology major =[tex]\frac{20}{250} =0.018[/tex]

What are word problems?

A word problem is a few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

Given is that one number is 10 less than 5 times the second number. Their sum is 26.

Let the numbers be [x] and [y] repsectively. Then, we can write that -

x + y = 26        ..... Eq[1]

x = 5y - 10        ..... Eq[2]

We can write -

x + y = 26

5y - 10 + y = 26

6y = 36

y = 6

Then, we can write [x] as -

x = 5 x 6 - 10 = 30 - 10 = 20

x = 20

Therefore, the two numbers are 6 and 20 respectively.

factor 1/8 out of 1/8x-49/8​

Answers

Answer:

1/8(x - 49)

Step-by-step explanation:

When we factor out something, we are basically finding common factors from multiple terms to take out. Example:

ab + ac; factored out: a(b + c)

If we want to factor out 1/8 from 1/8x - 49/8, we simply divide the two terms by 1/8.

[tex]\frac{1/8}{1/8x}[/tex] The 1/8 cancel out giving us x so:

1/8(x - __)

The next term,

[tex]\frac{49/8}{1/8}[/tex]

When two fractions divide, you flip the bottom one and multiply them both,

[tex]\frac{49}{8} *\frac{8}{1}[/tex]

giving us 49.

The answer is: 1/8(x - 49)

Answers

Answer:

P( -1.96 ≤ Z≤ 1.96) = 0.95

Step-by-step explanation:

Explanation:-

Given that the z -scores -1.96 and 1.96

we have to find   P( -1.96 ≤ Z≤ 1.96)

P( -1.96 ≤ Z≤ 1.96) = |A(1.96)+A(-1.96)|

                              = |A(1.96)+A(-1.96|   (∵A(-Z) = A(Z))

                            =  0.4750+0.4750

                            = 2×0.4750

The probability lies between  -1.96 to 1.96
