Answer:

About 41.5%

Step-by-step explanation:

Given:

A bowl has 8 green grapes and 15 red grapes. Henry randomly chooses a grape, eats it, and then chooses another grape.

To Find:

What is the probability that both grapes are red?

Answer choices:

about 39.7%

about 41.5%

about 42.5%

about 44.5%

Solution:

Since, there are 8 green grapes and 15 red grapes, the total number of grapes is 23 .

As the red grapes are 15..

Thus,

The probability of choosing a red grape the first time is 15/23.

Because out of the total 23 grapes only 15 were red grape.

The probability of choosing the red grape the second time will be 14/22. Because the number of red grapes has already decreased by one and so is the total number of grapes after first choice

Hence, the probability of choosing or eating two red grapes will be :

15/23×14/22

=105/253

=0.415

= 41.5%

Therefore, the probability that both grapes are red is about 41.5%

Step-by-step explanation:

Im glad i could help out.

Answer:

A) It would take 360 monthly payment to pay of the 30-year loan.

B) Her monthly payment would be $650.

C) The total paid back to bank over 30 years would be $234,000

D) The total amount of interest was $114,000 (95% interest back to the bank after 30 years).

Step-by-step explanation:

6.5 percent *120000 =

(6.5:100)*120000 =

(6.5*120000):100 =

780000:100 = 7800

6.5% of 120,000 is 7,800.

Every year Leaf U. Allone has to pay $7,800 to the bank.

12 months in a year.

7,800 ÷ 12 = $650

Every month Leaf U. Allone has to pay $650 to the bank.

Over 30 years of paying 7,800

Multiply 7,800 * 30

= $234,000

To find the interest,

subtract 120,000 from 234,000

= $114,000 in interest.

Meaning the home value went up.

Answer:

a) 35%

b) 6.67%

Step-by-step explanation:

a) The annual number of burglaries in 2012 would be 150% and since in 2013, it fell by 10%:

10% of 150 is 15 so 150-15 = 135%.

The actual percentage increase of burglaries is 135% - 100% = 35% not 40%.

b) In the second year, the percentage would have to decrease by 10% of the initial 150% so [tex]\frac{10}{150}[/tex] = [tex]\frac{1}{15}[/tex] which as a percentage would be 6.66666....% or 6.67%.

The number of burglaries actually changed in the two-year period will be 35% and the crime have to decrease in the second year in order for the change over the two-year period to actually be a 40% increase will be 6.7%

It is act of breaking and entering a dwelling at night to commit a felony such as theft.

The steps are as follow:

(x - 100) / 100 = 0.40

x - 100 = 40

x = 140

So, burglaries after the 10% reduction in 2013 would be 35% and change in burglaries over the two-year period to have 40% increase will be 6.7%.

Answer:

obtuse

Step-by-step explanation:

a² + b² = c²

Let's use the two shorter sides as legs.

a² + b² = 31² + 54² = 961 + 2916 = 3877

c = √3877 = 62.2655...

For the triangle to be a right triangle, the third side would have to have a length of 62.2655. The actual length of the third side is 69. 69 is greater than 62.3, so the angle between the sides 31 and 54 must be greater than 90°. Therefore the triangle is an obtuse triangle.

Considering the points M and N, the vector MN is component form is given by:

169.09 degrees

Step-by-step explanation:

Interior Angle of a polygon with 33 sides = (n-2) x 180/n degrees = (33-2) x 180/33 degrees = 169.09 degrees

33 sides

the size if each interior angle.

[tex] \frac{360}{33} [/tex]

[tex] = 10.91[/tex]

a) For the Jumping Jackrabbits, the MAD is of 3.6 and for the Leaping Lizards, the MAD is of 6.8.

b) Due to the higher value of the MAD, the Leaping Lizards have less consistent scores than the Jumping Jackrabbits.

Item a:

For the Jumping Jackrabbits, the mean and the MAD are given by:For the Jumping Jackrabbits, the MAD is of 3.6 and for the Leaping Lizards, the MAD is of 6.8.

M = (70 + 65 + 72 + 80 + 73)/5 = 72

MAD = (|70 - 72| + |65 - 72| + |72 - 72| + |80 - 72| + |73 - 72|)/5 = 3.6.

For the Leaping Lizards, the mean and the MAD are given by:

M = (61 + 47 + 70 + 63 + 54)/5 = 59

MAD = (|61 - 59| + |47 - 59| + |70 - 59| + |63 - 59| + |54 - 59|)/5 = 6.8.

For the Jumping Jackrabbits, the MAD is of 3.6 and for the Leaping Lizards, the MAD is of 6.8.

Item b:

Due to the higher value of the MAD, the Leaping Lizards have less consistent scores than the Jumping Jackrabbits.
