Answer:

At least 18 students scored below a 67.

Step-by-step explanation:

Given the 5 number summary of scores obtained by 37 students in a test worth 100 points :

55, 67, 73, 81, 98

Minimum = 55

Q1 = 67

Q2 = 73

Q3 = 81

Maximum = 98

Q1 = first quartile = 25%

Atleast 25 % scored below 67 (True)

25% of 37 students = 0.25 * 37 = 9.25

Atleast 9 students scored below 67 (True)

Median, Q2 = 50%

Score between Q2 and Q1 = 50% - 25% = 25% ;

Hence, atleast 25 students scored between 73 and 67 ; meaning (0.25 *37) = 9.25 students Hence. Atleast, 9 students scored between 73 and 67 (True)

Third quartile = 75%

Percentage above third quarterile = (100 - 75)% = 25%

Hence, atleast 25% scored above 81 (True)

The false statement is At least 18 students scored below a 67.

Answer:

(x+1)(2x+5)

Step-by-step explanation:

f(x) = 2x² + 7x + 5

Factor the expression by grouping. First, the expression needs to be rewritten as 2x²+ax+bx+5. To find a and b, set up a system to be solved.

a+b=7

ab=2×5=10

Since ab is positive, a and b have the same sign. Since a+b is positive, a and b are both positive. List all such integer pairs that give product 10.

1,10

2,5

Calculate the sum for each pair.

1+10=11

2+5=7

The solution is the pair that gives sum 7.

a=2

b=5

2x²+7x+5 as (2x²+2x)+(5x+5).

(2x²+2x)+(5x+5)

Factor out 2x in the first and 5 in the second group.

2x(x+1)+5(x+1)

Factor out common term x+1 by using distributive property.

(x+1)(2x+5)

Answer:

Not a function.

Step-by-step explanation:

The vertical line test is when you run a line -vertical or AKA: up and down- through the path of a graph if the line runs through the path more than once, it has failed the vertical line test, and therefore is not a function. The graph in question fails this test, and cannot be a function.

Answer:

1/5

Step-by-step explanation:

6/30 can be simplified by finding the LCD (least common denominator), which is 6

divide both the top & bottom by 6

6/6 = 1

Answer:

Step-by-step explanation:

$1500-$250 = $1250

You need to save an additional $1250.

The question did not include a pay rate.

Suppose you earn x dollars an hour.

$1250 × (1 hour)/($x) = (1250/x) hours

You need to work 1250/x hours.

Answer:

solve the 3y and 2y first

Step-by-step explanation:

Answer:

y = 2.

Step-by-step explanation:

We need to have  y terms on one side of the equation and numbers on the other side:-

3y - 4 = 6 -  2y    

 Add 2y to both sides:              

3y + 2y - 4 = 6 - 2y + 2y

5y - 4 = 6    

Add 4 to both sides:                      

5y  - 4 + 4 = 6 + 4

5y = 10

y = 10/5

y = 2.

Answer:

150,000.

Step-by-step explanation:

Given that an insector found 24 defective cameras during an inspection and this is 0.016% of the total numbers of cameras inspected, to determine how many cameras were inspected the following calculation must be performed:

0.016 = 24

100 = X

100 x 24 / 0.016 = X

2,400 / 0.016 = X

150,000 = X

Thus, the total number of cameras that were inspected is 150,000.

Answer:

Step-by-step explanation:

180+220+88 = 488 km

2.5+4.4+2.2 = 9.1 h

(488 km )/(9.1 h) = (488/9.1 km)/h ≈ 53.6 km per hour

Given:

The value of a house is 600,000 in 2005.

It increased by 25% in 2006 and 10% in 2007 but dropped by 15% in 2007.

To find:

The value of the house in 2008.

Solution:

We have,

Value of house in 2005 = 600,000

It increased by 25% in 2006.

Value of house in 2006 = [tex]600,000+\dfrac{25}{100}600,000[/tex]

                                        = [tex]600,000+150,000[/tex]

                                        = [tex]750,000[/tex]

It increased by 10% in 2007

Value of house in 2007 = [tex]750,000+\dfrac{10}{100}750,000[/tex]

                                        = [tex]750,000+75,000[/tex]

                                        = [tex]825,000[/tex]

But it dropped by 15% in 2007.

Value of house in 2008 = [tex]825,000-\dfrac{15}{100}825,000[/tex]

                                        = [tex]825,000-123,750[/tex]

                                        = [tex]701,250[/tex]

Therefore, the value of the house in 2008 is 701,250.

Answer:

Step-by-step explanation:

The amount of money that Ms. Gonzalez spends on small folders than large folders will be $12.75.

The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.

Ms. Gonzalez buys folders for her office. She buys 4 small folders for every 1 large folder. She buys 15 folders in all. Small folders cost $0.75, and large folders cost $1.25.

Let 'x' be the number of small folders and 'y' be the large folders. Then the equations are given as,

x + y = 15          ...1

y = 4x              ...2

From equations 1 and 2, then we have

x + 4x = 15

5x = 15

x = 3

Then the value of 'y' is given as,

3 + y = 15

y = 12

The cost of the small folder is given as,

⇒ $0.75 × 3

⇒ $2.25

The cost of the large folder is given as,

⇒ $1.25 × 12

⇒ $15

The difference is given as,

⇒ $15 - $2.25

⇒ $12.75

The amount of money that Ms. Gonzalez spends on small folders than large folders will be $12.75.
