Answer:
59.1 for the mean
Step-by-step explanation:
You add all the numbers together and divde it by the amount of numbers there are.
Answer:
Mean= 59.1
Median= 58
Range= 11
Step-by-step explanation:
Mean= Total data/Number of given datas
= 60+58+54+56+63+65+62+59+56+58/10
Mean = 591/10= 59.1
Median= Middle value
= 65, 63, 62, 60, 59, 58, 58, 56, 56, 54
Median= 58
Range= Highest value- Lowest value
= 65-54
Range= 11

Use elimination to sole the system of linear equations and determine how much each bracelet cost, x and how much each necklace coast. (x,y)
Answers
Answer:
bracelet $18necklace $58Step-by-step explanation:
You are given that ...
40x +40y = 3040
80x +40y = 3760
Eliminate y by subtracting the first equation from the second:
(80x +40y) -(40x +40y) = (3760) -(3040)
40x = 720
x = 18
Using the first equation to find y, we have ...
40y = 3040 -40x
y = 76 -x . . . . . divide by 40
y = 76 -18 = 58
The cost of a bracelet is $18; the cost of a necklace is $58.

Given f(x) = 2x² + 8x - 4 and g(x) = 5x +6, find 3f(x) – 2g(x).
Answers
Step-by-step explanation:
When the problem says 3f(x), it means that you are multiplying f(x) by 3. The same goes for 2g(x).
[tex]3(2x^2+8x-4)= 6x^2+24x-12[/tex]
[tex]2(5x+6) = 10x+12[/tex]
Now, we subtract f(x) from g(x) after being multiplied.
[tex](6x^2+24x-12)-(10x+12)[/tex]
[tex]6x^2+14x-24[/tex]
Determine the value of x
Answers
Answer:
The value of x is 12 feet
Step-by-step explanation:
The shape in question is a composite shape. We can see that x is both the base of the triangle and the breadth of the rectangle.
To get the area of the shape, we will have to add the area of the rectangle to the area of the triangle.
Area of rectangle = length X breadth
Area of triangle = 1/2 base X height.
However, to calculate the area of the triangle, we need to find its height first.
The next step is to get the height of the triangle. Observing the shape properly, we can see that we can get the height by subtracting the length of the rectangle from the overall length of the shape.
Height of triangle = 16 ft - 10 ft = 6 ft
recall area = 156 square feet.
We now have most of our missing dimensions
We can now set up an equation as follows:
[tex](10 \times x) +0.5 \times x \times 6 = 156[/tex]
[tex]10x +3x=156\\13x=156\\x=12 feet[/tex]
Therefore the value of x is 12 feet

Natasha bought a necklace and 4 identical bracelets. A necklace cost $294 more than a bracelet. Natasha paid $3519 for her purchases. What was the cost of the necklace?
Answers
Cost of necklace is $939 and cost of bracelet is 645
Cost based problem:Given that;
Number of necklace = 1
Number of bracelets = 4
Cost of necklace = Cost of bracelets + 294
Find:
Cost of necklace
Computation:
Assume;
Cost of bracelets = a
Cost of necklace = a + 294
So,
4a + a + 294 = 3519
5a + 294 = 3519
5a = 3225
a = 645
Cost of necklace = 645 + 294
Cost of necklace = $939

Answers
Answer:
(x + 1 s 1) n (x + 12 1)
(x +1<1) n (x + 1 > 1)
Step-by-step explanation:
Just simplify each the statements.
Then compare and and see if the statements are contradictory and therefore FALSE, if so, then there is no solution.
(x + 1<-1) n (x + 1< 1)
(x <-2) n (x < 0) which is true, so there is a solution.
(x + 1 s 1) n (x + 12 1)
this doesn't make sense so there is no solution.
(x +1<1) n (x + 1 > 1)
(x < 0) n (x > 0)
This is not possible, the statements are contradictory and therefore FALSE, so there is no solution.
What are the coordinates of point C
Not sure if I’m right or wrong
Answers
Answer:
x always comes first so that is 0
then it is y and that is -6 so the answer is (0,-6) aka B
IF i could get brainliest that would be great
Answer: (0, -6)
Step-by-step explanation: When finding the coordinates of a given point, be very careful with your signs.
On the x-axis, left means negative and right means positive and
on the y-axis, down means negative and up means positive.
So to find the coordinates for point C, we start at the origin
which is where the x-axis and y-axis intercept.
So, we go 0 units to the left or right and 6 units down.
So that's (0, -6).
Remember that the first number in the ordered pair represents the x-coordinate or how far we move to the left or right from the origin and the second number represents the y-coordinate or how far we move up or down from the origin.

. el aula negra tiene, tiene el 20% de los estudiantes.
Los hombres están reportados de manera uniforme, pues en cada aula hay un 40% de hombres, si se selecciona estudiante al azar:
a) ¿Cuál es la probabilidad de que sea una mujer del aula azul?
b) ¿Cuál es la probabilidad de que sea hombre del aula negra?
Answers
Answer:
To solve this problem, we just have to multiply.
(A) The event: woman in the blue class room is related to 60% of women representation and 30% of students representation in the blue classroom.
Therefore, the chances of choosing a woman student from the blue classroom is
[tex]P= 0.60 \times 0.30 = 0.18[/tex]
Which is equivalent to 18% of probability.
(B)We apply the same process to find the probability of choosing a man from the black classroom.
[tex]P= 0.40 \times 0.20 = 0.08[/tex]
Which is equivalent to 8% of probability.
Therefore, there's a 18% of chances of choosing a woman from the blue classroom, and there's a 8% of changes of chossing a man from the black classroom.JC is making a poster for Bike Safety Week.

We can use two data points to find the linear function that relates the two quantities. For example, a linear function relating calories (C) consumed over days(d) can be generated from the following data: -After 3 days 4,100 calories have been consumed. -After 8 days 10,600 calories have been consumed. The slope of this function is________ and indicates the number of calories consumed each day. The y-intercept of this function is_________ and indicates the calories consumed at day . This function can be modeled by C=______
Answers
Answer:
Step-by-step explanation:
Let the number of days be x because x is the independent variable
Any y is the number of calories consumed the dependent variable.
Now slope = y2 - y2/ x2 - x2
= 10600-4100/8-3
= 6500/5 = 1300
From our analysis we know it consumes 1300 per day so ideally on day 3 we expect him to consume 1300x3= 3900
But the given value is 4100
This means it's inherent energy is 4100-3900= 200
This is the y- intercept and it occurs when x= 0
from the above explanation we know that
C = 200. and it's the y- intercept.
Look at the general equation of a line
y = mx + C; when x= 0, y = C; note we define C as the value of y when x = 0

A statistics student wants to examine if there is a difference in the commute times for students and faculty at her community college. She collected data from a random sample of 10 faculty and 10 students. The commute times (in minutes) are given below.
Faculty 5 12 12 15 12 22 25 30 35 45
Students 10 12 14 15 15 20 22 24 25 30
Determine and enter the five-number summary for the commute times (in minutes) of the two samples. Include all calculations in your answer, round to two decimal places.
Answers
Answer:
Step-by-step explanation:
To find the five-number summary for the commute times (in minutes) of the two samples, we would determine the lowest, highest, first quartile, median and third quartile for each set of values.
1) Considering the data for faculty, arranging in ascending order, it becomes
5 12 12 12 15 22 25 30 35 45
Minimum = 5
Maximum = 45
Median = (15 + 22)/2 = 18.5
Placing the median in the data, it becomes
5 12 12 12 15 18.5 22 25 30 35 45
The median divides the data into the lower and upper halves
First quartile is the 25% mark. It is also the middle of the lower halve. Therefore,
First quartile = 12
Third quartile is the 75% mark. It is also the middle of the upper halve. Therefore,
Third quartile = 30
2) Considering the data for students, arranging in ascending order, it becomes
10 12 14 15 15 20 22 24 25 30
Minimum = 10
Maximum = 30
Median = (15 + 20)/2 = 17.5
Placing the median in the data, it becomes
10 12 14 15 15 17.5 20 22 24 25 30
The median divides the data into the lower and upper halves
First quartile is the 25% mark. It is also the middle of the lower halve. Therefore,
First quartile = 14
Third quartile is the 75% mark. It is also the middle of the upper halve. Therefore,
Third quartile = 24

if D is the center of the circle below and AC measures 48, what is the measure of ABC
Answers
Answer:
24
Step-by-step explanation:
How do we know that a circle must complete up to 180, then we have to:
180 - 48 = 132
Now knowing this distance we can also know the other, starting from the same concept, in addition to what the circle below is like, a semicircle refers to so we divide by 2:
(180-132) / 2 = 24
Therefore the answer is 24.
We can also do it ABC is half of ADC. So ABC = 48/2 = 24
24 is the answer
