Answer:
Step-by-step explanation:
Mean = sum of variables/sample size
Sum of variables = 5+8+18+1+14+6+8+13+8+19
Sum of variables = 100
Sample size = 10
Mean = 100/10
Mean = 10
Median is the value at the centre after rearrangement.
On rearrangement
1,5,6,8),8,8,(13,14,18,19
Median = 8+8/2
Median = 16/2
Median = 8
Mode is the value with the highest frequency. The value that occur the most. From the datas, the mode is 8 since it occurred 3 times.

Kaitlyn is making big goods for charity bake sale he places a tray of scones a tray of muffins and a tray of cookies in the oven discounts bake for 15 minutes the muffins bake for 12 minutes and the cookies bake for 10 minutes when one trays done he removes it and replace it with another tray at the same I don't how many minutes after kaylan put the trays in the oven when he 1st remove the scones muffins and cookies at the same time
Answer:
So:
Counting from a given time t = 0min, we know that:
Each 15 mins she removes the scones
Each 12 mins she removes the muffins
Each 10 mins she removes the cookies.
So when will she remove both at the same time?
Well, this will happen in the smallest common multiple of 15, 12 and 10.
or at LCM(10, 12, 15).
How we find it?
well, in this case is easy.
All the multiples of 10 end with a zero.
So let's find the multiples of 12 and 15 that also end with a zero:
12*6 = 60
15*4 = 60
and
10*6 = 60
So the LCM(10,12,15) = 60.
Another way is by calculating:
10*12*15/(GCF(10,12)*GCM(12,15)*GCM(10,15)
Where GCF = greatest common factor.
Between 10 and 12 is 2.
Between 12 and 15 is 3
Between 10 and 15 is 5.
Then:
10*12*15/(2*3*5) = 60.
This means that 60 minutes after she starts, she will remove the scones, muffins and cookies at the same time.

angelo wants to buy a laptop and an android phone to be used in his online class. He paid a total of Php 24, 200.00 for both gadgets. The price of the laptop is Php 3, 800.00 more than the price of the android phone.
Answer:
laptop: 14000
phone: 10200
Step-by-step explanation:
laptop: x + 3800
phone: x
x + 3800 + x = 24200
2x + 3800 = 24200
2x = 20400
x = 10200
laptop: 10200 + 3800 = 14000
phone: 10200
What is the slope of the line that passes through the pair of points?
( 1,7 ) , ( 10,1 )
Answer:
m = -2/3
Step-by-step explanation:
We can find the slope of the line from the given two points:
m = (y2-y1)/(x2-x1)
m = (1-7)/(10-1)
m = -6/9
m = -2/3
3=−2 |14s−5| +3 can i get a simple explination im kind of dumb lol
Answer:
s=5/14
Step-by-step explanation:
cancel equal terms on both sides of the equation
0=-2 x |14s-5|
swap the sides of the equation
-2 x |14s-5|=0
divide both sides of the equation by -2
|14s-5|=0
when the absolute value of 14s-5= 0, then 14s-5=0
move the constant to the right-hand side and change its sign
14s=5
now divide both sides of the equation by 14
s=5/14

Quadration Equation
X^2 - 6x - 7 = 0
Answer:
x = - 1, x = 7
Step-by-step explanation:
Given
x² - 6x - 7 = 0
Consider the factors of the constant term (- 7) which sum to give the coefficient of the x- term (- 6)
The factors are - 7 and + 1, since
- 7 × 1 = - 7 and - 7 + 1 = - 6, thus
(x - 7)(x + 1) = 0
Equate each factor to zero and solve for x
x - 7 = 0 ⇒ x = 7
x + 1 = 0 ⇒ x = - 1

When measuring the sides, triangles can be classified as acute, scalene and isoceles
Answer:
Yes, When measuring the sides, triangles can be classified as acute, scalene, and isosceles
Step-by-step explanation:
In any triangle, there are at least two acute angles
The types of triangles according to their angles are:
Acute-angled triangle ⇒ 3 angles are acuteRight-angled triangle ⇒ 2 acute angles and 1 right angleObtuse-angled triangle ⇒ 2 acute angles and 1 obtuse angleThe types of triangles according to their sides are:
Equilateral triangle ⇒ 3 equal sidesIsosceles triangle ⇒ 2 equal sidesScalene triangle ⇒ 3 different sideYou can classify the type of the triangle according to its angle using the measuring of its sides.
If a triangle has sides length a, b, c where c is the longest side
∵ a² + b² > c²
∴ The triangle is an acute-angled triangle
∵ a² + b² = c²
∴ The triangle is a right-angled triangle
∵ a² + b² < c²
∴ The triangle is an obtuse-angled triangle
You can classify the type of the triangle according to its sides using the measuring of its sides.
If a triangle has sides lengths a, b, c
∵ a, b, c have unequal lengths
∴ The triangle is scalene
∵ a and b or a and c or b and c have equal lengths
∴ The triangle is Isosceles
∵ a, b, c have equal lengths
∴ The triangle is equilateral
Yes, When measuring the sides, triangles can be classified as acute, scalene, and isosceles
Owen made 60% of the shots he attempted during his hockey practice. He made 18 shots. How many shots did Owen attempt during his hockey practice?
Answer:
10.8 shots
Step-by-step explanation:
Owen made 60% of the shots he made, and he made 18 shots in total. Therefore, we would take 60% of 18. The answer we get is 10.8, but we can't have a part of a shot.

One solution to a quadratic equation is x = 1 + 8i. What is the other solution?
We'll assume the quadratic equation has real coefficients
Answer:
The other solution is x=1-8i.
Step-by-step explanation:
The Complex Conjugate Root Theorem
if P(x) is a polynomial in x with real coefficients, and a + bi is a root of P(x) with a and b real numbers, then its complex conjugate a − bi is also a root of P(x).
The question does not specify if the quadratic equation has real coefficients, but we will assume that.
Given x=1+8i is one solution of the equation, the complex conjugate root theorem guarantees that the other solution must be x=1-8i.
Answer:
the answer would be x= 1-8i

An appliance store sells microwave ovens and has many different styles to choose from. A handout from the store contains details about brand, price, number of power settings, and color. What are the individuals in this data set?
a) microwave ovens
b) brands
c) prices
d) colors
Answer:
a) microwave ovens
Step-by-step explanation:
Since we don't know what the dataset is, we cannot say with certainty what its elements are. The first sentence talks about microwave ovens, so it may be reasonable to assume that will be the members of the data set.
_____
Additional comments
In computer programming terms (as for a shopping web site, for example), the data set would consist of tuples of ...
(brand, price, number of power settings, color)
and perhaps other attributes, such as dimensions, home/commercial, length of warranty, and more. That is, the appropriate answer would be "all of the above."
