Given:
In triangle XYZ, P is the centroid of triangle XYZ, YP = 8, QP = 5, YZ = 10.
To find:
The measure of median YS.
Solution:
We know that a centroid divides a median in 2:1.
P is the centroid and YS is the median. So,
[tex]YP:PS=2:1[/tex]
Let the measure of YP and PS are 2x and x.
It is given that the measure of YP is 8.
[tex]2x=8[/tex]
[tex]x=\dfrac{8}{2}[/tex]
[tex]x=4[/tex]
[tex]PS=4[/tex]
Now, the measure of YS is:
[tex]YS=YP+PS[/tex]
[tex]YS=8+4[/tex]
[tex]YS=12[/tex]
The measure of median YS is 12 units. Therefore, the correct option is (a).
i want to fined out that
a^2+b^2
________is equal to?
a+b
Answers
Answer:
(a+b)²-2ab
Step-by-step explanation:
First we need to factorize (a+b)²
(a+b)² = a² + 2ab + b²
(a+b)² = a²+b²+2ab
Subtract 2ab from both sides
(a+b)² - 2ab = a²+b²+2ab - 2ab
(a+b)²-2ab = a²+b²
Swap;
a²+b² = (a+b)²-2ab
Hence the expression of a² + b² is (a+b)²-2ab
The sum of three numbers is 84, the second number is 2 times the 3rd , the first number is 8 more than the 3rd. What are the numbers
Answers
Answer:
a = 27
b = 38
c = 19
Step-by-step explanation:
a + b + c = 84
b = 2c
a = 8+c
8+c +2c+c = 84
4c + 8 = 84
4c = 76
c = 19
b = 2(19) = 38
a = 8 + 19 = 27

Find x
x + 11 = 3x + 1 (substitution)
Collect like terms
x - 3x = -11 + 1
-2x = -10
Divide both sides by -2
x = -10/-2
x = 5
✔️FG = x + 11
Plug in the value of x
FG = 5 + 11
FG = 16

Step-by-step explanation:
Jack invested $7100 compounded continuously at an interest rate of 3⅝% which is 0.03625
Formula for future value of continuous compounding is;
FV = PVe^(rt)
Where;
FV is future value
PV is present value
r is interest rate
t is time
After 19 years;
FV = 7100 × e^(0.03625 × 19)
FV = $14137.697
Henry invested $7100 compounded monthly at an interest rate of 3⅜% which is 0.03375.
Formula for FV of monthly compounding is;
FV = PV(1 + i)^(n)
FV = 7100(1 + 0.03375)^(19)
FV = $13339.922
Thus, amount Jack has more than Henry = 14137.697 - 13339.922 = $797.775
Approximating to the nearest dollar gives $798

if 4x=3y, which shows the ratio of x to y in simplest form?
Answers
Answer:
B
Step-by-step explanation:
4x=3y
x/y=3/4
Just like the photo I attached
If 4x=3y, then 3/4 is the ratio of x to y in the simplest form. Option B is correct.
The ratio of x to y can be determined by dividing both sides of the equation 4x = 3y by y:
4x/y = 3y/y
4x/y = 3
To express the ratio of x to y in simplest form, we divide both sides of the equation by 4:
x/y = 3 / 4
Therefore, the ratio of x to y in simplest form is 3/4. option B is correct.

Gwen makes 30 cookies in 3/4 hour. At this rate, how many cookies could Gwen make in 3 hours
Answers
Answer:
120 cookies
Step-by-step explanation:
3 / (3/4) = 4
30 * 4 = 120
Answer:
120
Step-by-step explanation:
3/4 of an hour is the same as 45 minutes. If she is doing this in an even pace, we can figure out how many cookies she's made in 15 minutes. (This will make the problem easier for us to solve.)
45÷3=15
30÷3=10
We now that in 15 minutes she can make 10 cookies. There are 180 minutes in three hours so we can divide 180 by 15 to know how many rounds of 15 there is.
180÷15 =12
Know we know that there are 12 rounds of 15 in three hours. We also know that in 15 minutes she can make ten cookies so all we have to do now is to multiply 12×10 to get 120. She can make 120 cookies in three hours.

You mix 3/4 quart of blue paint for every 5/6 quart of yellow paint to make 4 3/4 quarts of green paint. How much blue paint and how much yellow paint do you use?
Answers
Answer: We need 2.5 quarts of yellow paint.
Step-by-step explanation:
As per given, The ratio of blue paint to yellow paint is [tex]\frac34: \frac{5}{6}[/tex].
[tex]=3\times6:5\times4\\\\=18:20\\\\ =9:10[/tex]
Total green paint = [tex]4\frac34[/tex] quarts
Quantity of yellow paint required = [tex]\frac{10}{9+10}\times4\frac34[/tex]
[tex]=\frac{10}{19}\times\frac{19}{4}\\=\frac{5}{2}\\=2.5\ $$ quarts$$[/tex]
Hence, We need 2.5 quarts of yellow paint.
To find this take the average of the absolute values of the differences between each member of a data set in the mean of the data set
Answers
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the dataset is missing; However, one can deduce that the question implies that you calculate the mean absolute deviation of the missing dataset.
Take for instance, the dataset is: 1, 2, 2, 3, 3, 5, 8
Calculate the mean:
[tex]\bar x = \frac{\sum x}{n}[/tex]
[tex]\bar x = \frac{1+2+2+3+3+5+8}{7}[/tex]
[tex]\bar x = \frac{24}{7}[/tex]
[tex]\bar x = 3.43[/tex]
Next, proceed to the instruction in the question;
Which is:
[tex]M = \frac{1}{n}\sum\limits^{n}_{i=1}|x_i - \bar x|[/tex]
So, we have:
[tex]M = \frac{1}{7}(|1-3.43| + |2 - 3.43| + |2 - 3.43| + |3 - 3.43| + |3 - 3.43| + |5 - 3.43| + |8 - 3.43|)[/tex]
[tex]M = \frac{1}{7}(|-2.43| + |- 1.43| + |-1.43| + |- 0.43| + |-0.43| + |1.57| + |4.57|)[/tex]
Remove absolute brackets
[tex]M = \frac{1}{7}(2.43 + 1.43 + 1.43 + 0.43 + 0.43 + 1.57 + 4.57)[/tex]
[tex]M = \frac{1}{7}*12.29[/tex]
[tex]M = 1.76[/tex]

Melanie ran the 400-meter dash six times during track practice. Her times are shown in the table to the left. If she drops her slowest time, which measure of center is affected the most, mean or median? Explain
Answers
Answer:
Mean
Step-by-step explanation:
The median is only the middle part of the set of numbers (from the smallest number to the biggest.) if the slowest time is 3 or 4 in that set of numbers then well bad luck I guess, but for mean it is all of them added up then divided by 6 ( the amount of numbers) so I would say mean.
