Answers

Answer:

Shown below.

Step-by-step explanation:

The table showing the umber and frequency of a certain ocean's hurricanes annually from 1930 through 2005 is:

   Number:     0     1      2     3      4    5     6     7    8     11     12      

Frequency:    5    16    20   14      3    5     4     4    2      1       1

The probability of an events, say E is the ratio of the number of favorable outcomes to the total number of outcomes.

[tex]P(E)=\frac{n(E)}{N}[/tex]

Compute the probabilities of 0 - 12 hurricanes each season as follows:

Number Frequency Probability

     0       5             0.07

     1              16                   0.21  

     2     20             0.27

     3      14             0.19

     4       3             0.04

     5       5             0.07

     6       4             0.05

     7       4             0.05

     8       2             0.03

    11       1                     0.01

    12         1              0.01

 Total     75             1.00

Emma wants to stain a circular deck that has a diameter of 12 m. The cost of the wood stain is $3.25
per square meter.
To the nearest dollar, how much will it cost Emma to stain the entire deck?
Use 3.14 for

Answers

Answer:

$1469

Step-by-step explanation:

diameter of deck = 12 m

diameter = 2*radius

thus

12 m = 2*radius

radius = 12m / 2 = 6 m

area of circle is given by [tex]\pi r^{2}[/tex]

where r is the radius

thus, area of given deck with radius = 12 m

[tex]\pi r^{2} = 3.14*12^{2} \\=> 3.14*144 = 452.16[/tex]

Thus, area of given deck is 452.16 meter square

given

The cost of the wood stain is $3.25 per square meter

cost of 1 meter square wood stain =  $3.25

since we have to find to stain the entire deck which has area 452.16 meter square , we multiply both side of equation by 452.16

cost of  452.16 meter square wood stain =  $3.25*452.16 = $1469.25

Thus,

it will cost $1469 to the nearest dollar for   Emma to stain the entire deck

Jenny has only 3 1/2 cups of flour in her house. She needs 1 5/8 cups for a brownie recipe. Her sister Jody needs 1 3/4 cup flour for her cookie recipe. Will there be enough flour for both recipes?

Answers

Answer:

yes, Jenny has enough flour for both recipes

Step-by-step explanation:

First, find what Jody and Jenny need for both their recipes. For this, we need a common denominator, 8

1 5/8=13/8

3/4=6/8

13/8+6/8=19/8

Jody has 3 1/2 cups of flour, which is 7/2 cups or 28/8.

Now we need to make sure that 28/8 is greater than 19/8

28>9.... so she has enough flour!

Which of the following is not equal to the rational number 7/4 ?

Option 1: 14/8
Option 2: 10/7
Option 3: 1.75
Option 4: 1 3/4

YOU COULD PICK MORE THEN ONE OPTION

Answers

Answer:

(2)  [tex] \frac{10}{7} [/tex]

Step-by-step explanation:

Given the rational number, [tex] \frac{7}{4} [/tex], the following can be said to be equal to the rational number:

1. [tex] \frac{14}{8} [/tex]

Simplify the fraction

[tex] \frac{2*7}{2*4} [/tex]

[tex] = \frac{7}{4} [/tex]

Therefore,  [tex] \frac{14}{8} = \frac{7}{4} [/tex]

3.  [tex] \frac{7}{4} = 1.75 [/tex] (using your calculator)

4. [tex] 1\frac{3}{4} [/tex]

Convert from mixed fraction to improper fraction

[tex] 1\frac{3}{4} = \frac{7}{4} [/tex]

[tex] \frac{10}{7} [/tex] ≠  [tex] \frac{7}{4} [/tex]

The answer is (2)  [tex] \frac{10}{7} [/tex]

Solve for x and y in the diagrams below.

Answers

1. x = 13, y = 11.5

2. x = 39, y = 123

Step-By-Step Explanation: For the first diagram, you can see that 10x - 42 = 6x + 10 by way of vertical angles. Vertical angles are two opposite angles created by the same two lines, meaning that they will ALWAYS be congruent. Solving for x, you get that 4x = 52, or that x = 13. There is another thing. Both of the diagrams have a total angle measurement of 360, since they both go all the way around. Knowing that, 6x + 10 + 8y must be equal to half of that, or 180. Solving for 88 + 8y = 180 (since you know the value of x), you know that 8y = 92, or x = 11.5.

For number two, the concept is very similar, but this time there's more angles. You can immediately see that there are 3 pairs of vertical angles. The value of the angle squishes between the x - 10 and the 3x + 6 is x - 11; again, vertical angles. The angle squished between 3x + 6 and x - 11 is x - 10 (vertical angles!). Last, you know that 3 x + 6 = y, since they are vertical angles. Combining 2(x-11) and 2(x-10) and 2(3x+6) [remember, y = 3x + 6!!], you get that 10 x = 390, and x = 39. Plug that in for the value of y, which is 3x + 6, giving you 123 degrees.
