1.38 is the mean of the amount of rainfall over the course of the week
Answer:
1.4 inches (1 decimal place)
Step-by-step explanation:
To calculate the mean you get the sum of all the terms required and divide by the number of terms you summed up.
All of the terms in the table sum up to 29/3. 29/3 divided by 7 (number of days in a week) = 1.3809..., which you can round to 1.4 inches

to find
Step-by-step explanation:
Answer:
108
Step-by-step explanation:
So we can break this figure into 2 shapes. A rectangle and a right triangle.
Once we do that, we can solve the area for each shape.
Rectangle: 6 x 3 = 18
For the triangle, we'll need to find the sum of 6 + 6, which would be 12 to find the missing height for the triangle. Then we can find the area.
Triangle: (12 x 15)/2 = 90
We can then add our two answers up to get our final answer.
18 + 90 = 108

\(\frac{16}{27}\)
Step-by-step explanation:
From the table, we notice that the total number of students is:
\(3+10+8+6=27\)
Then, along the second column of the table, we notice that the number of students who do not have a brother is:
\(10+6=16\)
So, the probability that a randomly chosen student does not have a brother is:
\(\frac{\text{number of students who do not have a brother}}{\text{total number of students}}=\frac{16}{27}\)

Using inverse operations is a direct way to solving equations
What is the Golden Rule for solving equations?
Answers
Answer:
Do unto one side of the equation, what you do to the other!
Step-by-step explanation:
An equation is like a balance scale. If we put something on, or take something off of one side, the scale (or equation) is unbalanced. When solving math equations, we must always keep the 'scale' (or equation) balanced so that both sides are ALWAYS equal.
Answer:
Keeping the equation balanced.
Step-by-step explanation:
You need to keep the equation balanced on both sides of the equal sign, like when you need to get rid of the number 4 on one side you have to do the same thing on the other side.

Below is a single die and a spinner with the numbers from 1 to 8.
(A) if the die is tossed and the pointer is spun what is the problability of getting a 5 on the die and a 7 on the spinner?
(B) What is the problability of getting a number less than 3 on the die and a number greater than 5 on the spinner?
Answers
Answer:
(A) P(5 on die) = 1/6, P(7 on spinner) = 1/8
(1/6)(1/8) = 1/48
(B) P(less than 3 on die) = 2/6 = 1/3
P(greater than 5 on spinner) = 3/8
(1/3)(3/8) = 1/8

What is the ordered pair of the final point?
A) (6, 4)
B) (4, 5)
C) (5, 3)
D) (5, 4)
Answers
Answer:
d) (5,4)
Step-by-step explanation:
Answer:
D. (5, 4)
Step-by-step explanation:
First, we need to know how coordinate [order] pair works.
(x, y)
That means, (5, 4) is 5 unit on the x-axis and 4 unit on the y-axis.
East means to the right on the graph (+) ;
South means going downward on the graph (-) ;
West means to the left on the graph (-) ;
North means going upward on the graph (+) .
So first, (5, 4) 5 units east meaning that we are moving the x-axis and moving right. 5 [in the order pair] + 5 [unit east] = 10
After the first step, we have (10, 4)
Moving (10, 4) 4 units south meaning that we are moving the y-axis and moving downward on the graph. 4 [in order pair] - 4 [unit south] = 0
After the second step, we have (10, 0)
Moving (10, 0) 4 units west meaning that we are moving the x-axis again and moving left this time. 10 [in order pair] - 4 [unit west] = 6
After the third step, we have (6, 0)
Moving (6, 0) 4 units north meaning that we are moving the y-axis again and moving upward on the graph. 0 [in order pair] + 4 [unit north] = 4
After the forth step, we have (6, 4)
Moving (6, 4) 1 unit west meaning that we are moving the x-axis again and moving left. 6 [in order pair] - 1 [unit west] = 5
After the final step, we have (5, 4)
Therefore, the answer to this question is D. (5, 4)
Though there is an easier version of this, which require some brain to do, but here's how-
Same above, we need to know that east and west moves sideways (east use +, west use -)
And north and south moves up and down (north use +, south use -)
And then we need to sort out how many steps moves sideways and how many steps moves up & down.
5 units east, 4 units west, and 1 unit west. And we put this in an equation for the x-axis. 5 [original] +5 [units east] -4[units west] -1[units west] = 5
Which would still get us 5 for the x-axis.
4 units south and 4 units north balanced out, which still is 4 for the y-axis.
Put the order pair together: (5, 4)
And we got the same answer: D. (5, 4)
I hope this helps!

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

In a garden, 2/3 of the flowers are roses. Of the roses in the garden, 5/12 are yellow and the rest are red. What fraction of the flowers are red roses?
Answers
because 5/12 are yellow, the rest would be red. so 7/12. but total roses are only 2/3 of the whole garden.
tip: when you see "of" in a fraction problem, it means you can multiply them.
so, 7/12 OF 2/3 is just (7/12) * (2/3).
multiplying straight across and simplifying will get you to 7/18!

Answer: -5x - 3y + 1
Step-by-step explanation:
When you get a question that asks you to combine like terms, arrange the x terms together, the y terms together, and the numbers together. Be sure to keep the + and - signs in front of each term.
-10x + 5x + 3y - 6y - 7 + 8
Once the like terms are together, you can add and subtract.
-10x + 5x = -5x
