There are 80 girls and 70 boys in the sixth grade. Of these students, 11 girls and 7 boys are left handed. What percentage of the sixth graders are left handed?
Answers
Answer: 12%
Step-by-step explanation:
Total number of people in 6th grade: 70+80 = 150
Total numbers of lefties: 11 + 7 = 18
Percent:
18 ÷ 150 = 0.12
0.12 x 100 = 12
Answer:
12%
Step-by-step explanation:
80+70=150 which is the whole
11+7= 18 which is the part
The equation is
Part= Percent x Whole
18= % x 150 or 18 divided by 150 is
.12 or 12%

A basketball has a mass of 1 kg and is traveling 12 m/s.
What would happen to the velocity if the momentum of the basketball were cut in half?
Answers
Answer:
\(6\:\mathrm{m/s}\) (The velocity would also be halved)
Step-by-step explanation:
The momentum of an object is given as \(p=mv\) where \(m\) is the mass of the object and \(v\) is the velocity of the object.
Because mass is constant, if the momentum (\(p\)) was cut in half, the velocity of the basketball would also be halved:
Let \(p_1\) be the initial momentum and \(p_2\) be the final momentum:
\(\frac{1}{2}p_1=p_2,\\\frac{1}{2}mv_1=mv_2, \\\fbox{$\frac{1}{2}v_1=v_2$}\)
Therefore, the basketball's new velocity is \(\frac{1}{2}\cdot 12=\fbox{$6\:\mathrm{m/s}$}\).

8. What is the interquartile range for the data in Table 3 (Number of Siblings)?
9. What is the mean absolute deviation of the data in Table 3 (Number of Siblings)?
Answers
Answer:
The data in Table 1 answers the question of what the distribution of heights is in Thomas's class.
The data in Table 2 answers the question of what the distribution of weights is in Thomas's class.
The data in Table 3 answers the question of what the distribution of number of siblings is in Thomas's class.
The most appropriate measure of center for the data in Table 1 is the mean. The mean is the average of all the values in the data set. In this case, the mean height is 5'8".
The mean height of the students in Thomas's class is 5'8".
The most appropriate measure of center for the data in Table 2 is the median. The median is the middle value in the data set. In this case, the median weight is 150 pounds.
The median weight of the students in Thomas's class is 150 pounds.
The interquartile range (IQR) is a measure of variability that is calculated by taking the difference between the third and first quartiles. In this case, the IQR is 25 pounds.
The mean absolute deviation (MAD) is a measure of variability that is calculated by taking the average of the absolute values of the differences between the data values and the mean. In this case, the MAD is 10 pounds.

Considering area (A) of garden as 30 square feet:
30 = x(2x+7)
Now we need to expand it:
x(2x+7) = 2x^2 + 7x
2x^2 + 7x = 30
Adding this into an Algebra calculator gives us 5/2 or 2.5
So x = 2.5
To prove this:
2(2.5) + 7 = 12
14 * 2.5 = 30
(2x+7) x = 30
you can distribute to make this easier
2x^2 + 7x = 30
you can plug this into quadratic formula by setting the equation =0, so:
2x^2 +7x -30 = 0
where 2x^2 = a
7x = b
and -30 = c
you can plug this into your calculator and get an answer of
X = 2.5

y = 400/d²d is directly proportional to x²

Answers
Answer:
20
Step-by-step explanation:
This is an easy problem. All that is needed to do is you add up all the numbers, then divide that number by how many numbers you have.
Example: 17+24+26+13=80
80/4 = 20
Answer:
So the mean means the average of all the numbers, right? So that means all you have to do is add up all the numbers together, and divide by the amount of numbers there are.
so for this question...
17 + 24 + 26 + 13 = 80.
since it equals 80, and there are four numbers, (17, 24, 26, 13) divide 80/4.
80/4 = 20
your answer is 20!

What equation models the line? I need help pretty fast.
Answers
Answer: y= 21x
Step-by-step explanation:
As you can see, the line is steadily increasing. To make an equation for the line, we need to use the formula y=mx+b.
Step 1: Find the slope, "m"
m is the slope of the line, calculated by finding 2 points on the line, and using the formula rise÷run.
To do this, find a point on the line. (Make sure it's an actual point, not one that is in between the lines). In this example I will use 0,0. Then, find the nearest (actual) point on the line. That will be 1,21.
Now, we will use rise/run.
To get from the 2 points I listed, we must rise, or go up, 21. Then, we must "run", or go left or right 1. In this case we go left.
Therefore, the "rise"= 21, and the "run"= 1. Now 21÷1= 21, so the slope is 21.
Step 2: Find the y-intercept, "b"
b is the y intercept of the line, whch is the first point on the y axis that the line is on. In this line, the y intercept is 0.
Step 3: Write the equation
Now that we know what "m" and "b" stand for, we can replace these letters with the numbers by plugging in.
y=mx+b
y= 21x+0
y= 21x
*Note that when the y intercept ("b") is 0, you don't write it in the equation, but if it were a number other than 0, you would.
