Step-by-step explanation:
a.) 9
When you divide with a fraction you do the reciprocal of the fraction (basically flipping numerator and denominator) then multiplying (since the opposite of division is multiplication.
So if you flip
[tex]\frac{1}{9} [/tex]
It would be:
[tex] \frac{9}{1} [/tex]
9/1 is the same as 9 so:
1 times 9 = 9
b.) 15
Same thing like we did above, just do the reciprocal the multiply.
[tex] \frac{1}{5} [/tex]
Becomes
[tex] \frac{5}{1} [/tex]
5/1 is the same as 5.
3 times 5 = 15

What is the total area of the figure? (square inches)
Answers
Answer:
60
Step-by-step explanation:
TOTAL SURFACE AREA = AREA OF SQUARE+2×(AREA OF TRIANGLE)
=(6×6)+2×(1/2×6×4)
=36+24=60 square inches
I hope it helped you
Answer:
The area of the full figure is 60 square inches.
Step-by-step explanation:
There are 4 triangles and one square in this figure. We can start by figuring out the area of the middle square, which would be [tex]6*6=36[/tex] because we know the sides are all 6 inches.
Next, we can look at the triangles and see that their hypotenuses (the longest sides) are all the same length, that being 5 inches. This means that we only need to find the length of the third side and then multiply the area of one triangle by 4 to get the area of all the triangles.
The pythagorean theorem states that in any right triangle, [tex]a^2 +b^2=c^2[/tex], with [tex]c^2[/tex] being the length of the hypotenuse. Since we know the length of the hypotenuse is 5 and one of the legs of the triangle is 4, we can insert this into the equation: [tex]a^2+4^2=5^2[/tex], which when simplified all the way gives us that [tex]a=3[/tex].
Since a right triangle is half of a rectangle, the easiest way to find the area of the triangle is to multiply the measures of the two legs together and then divide by two: [tex](3*4)/2=6[/tex]. Therefore, we know that each triangle in the picture has an area of 6.
Finally, you need to add all of the areas together to find the area of the full figure: [tex]36+6+6+6+6=60 in^2[/tex]
The area of the full figure is 60 square inches.

(a) Determine the MAD of each data set. In your work, show the mean and the absolute deviation of
each data value in each set.
(b) Compare and interpret the MADs in context of the situation.
Answer:
Answers
Using it's concept, it is found that:
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.
What is the mean absolute deviation of a data-set?The mean of a data-set is given by the sum of all observations divided by the number of observations.The mean absolute deviation(MAD) of a data-set is the sum of the absolute value of the difference between each observation and the mean, divided by the number of observations.The mean absolute deviation represents the average by which the values differ from the mean.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.

Answers
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%

2108/10 = 210.8 (mean for Luis)
Darcy 231 + 210 + 245 + 259 + 286 + 245 + 231 + 244 + 236 + 228 = 2415
2415/10 = 241.5 (mean for Darcy)
Answer:
To find the median number of words in Darcy’s essays, first arrange the values in the data set in ascending order:
210, 228, 231, 231, 236, 244, 245, 245, 259, 286.
Because the number of values in the data set is an even number (10), the median is the mean of the two middle values, the fifth and sixth values, in the data set. The fifth and sixth values are 236 and 244, respectively. So,
median
