Find the area of the figure. A. 24.3 ft2 B. 38.1 ft2 C. 48.6 ft2 D. 35.7 ft2
The area of the figure is the amount of space on it, and the calculated area is 48.6 square feet
How to determine the area?The figure is a triangle with the following parameters:
Base = 20
Height = 4.86
The area of a triangle is:
Area = 0.5 * Base * Height
So, we have:
Area = 0.5 * 20 * 4.86
Evaluate
Area = 48.6
Hence, the calculated area is 48.6 square feet

Point B is between A and C. If AB = 3x, BC = 4x-2, and AC = 12, find the length of BC
Answer:
BC = 6 units
Step-by-step explanation:
given that B is between A and C , then
AB + BC = AC ( substitute values )
3x + 4x - 2 = 12
7x - 2 = 12 ( add 2 to both sides )
7x = 14 ( divide both sides by 7 )
x = 2
Then
BC = 4x - 2 = 4(2) - 2 = 8 - 2 = 6
Answer:
6
Step-by-step explanation:
from the question, since point B is between Ac
AC = AB + BC
12 = 3X+4X -2
3X+4X-2 = 12
7X = 12+2
7X = 14
dividing bothsides by 7
7X/7 = 14/7
X = 2
the length BC = 4X-2 = 4(2)-2 = 8-2= 6
length of BC = 6

You're looking for the equation of the line through the two yellow points, whose coordinates are (4, 0) and (8, 9).
Compute the slope:
(9 - 0) / (8 - 4) = 9/4
Using the point-slope formula, the equation of the line is
y - 0 = 9/4 (x - 4)
or
y = 9x/4 - 9
What is the probability of pulling a card from a deck of 52 cards and getting a king and a queen?
Answer:
4/52 or 1/13
Step-by-step explanation:
In a standard deck of 52 cards, there are 4 suits and each suit has 13 cards.
There are 4 kings, 4 queens, 4 aces, and 4 jacks.
So the probability of drawing a king would be:
4/52 = 1/13
Answer:
The probability of drawing a King is 4/52 or about . 0769, which is also the probability of drawing a Queen. The probability that a card drawn from the deck will be both a King and a Queen is zero. The probability that a card will be either a King or a Queen is 8/52.
Step-by-step explanation:
52 cards in a deck 4 queens and 4 kings

buffy's beverages has increasing profits each week during the hot summer months. Buffy finds that each week his profits increase by 20% over what they were the previous week. In his first week of business his profits were $200
The exponential function that gives the profit after x weeks is given by:

In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem:
Buffy finds that each week his profits increase by 20% over what they were the previous week, hence r = 0.2.In his first week of business his profits were $200, hence A(0) = 200.Thus, the equation is given by:

A bag contains 9 marbles: 2 are green, 3 are red, and 4 are blue. Raina chooses a marble at random, and without putting it back, chooses another one at random. What is the probability that both marbles she chooses are red? Write your answel as a fraction in simplest form.
=========================================================
Explanation:
There are 3 red out of 9 total
The probability of picking red at random is 3/9 = 1/3
If the first marble is not put back, then the chances of picking red again are now 2/8 = 1/4
Notice how I subtracted 1 from the numerator and denominator of 3/9 to get to 2/8. This is because the red count and the total count both go down by 1 each.
Now multiply the fractions mentioned:
(3/9)*(2/8) = (1/3)*(1/4) = (1*1)/(3*4) = 1/12
If you did this trial 12 times, then you should expect to get two reds about once. That's one way to interpret the probability of 1/12.
Side note: 1/12 = 0.0833 = 8.33% approximately

Given that l is the centroid of triangle CDE, find CH.
A. 3
B. 4
C. 8
D. 12
Answer:
D. 12.
Step-by-step explanation:
As I is the centroid G is the midpoint of CE, so
2x + 5 = 5x - 4
5+4 = 5x - 2x
3x = 9
x = 3.
x + 5 = 2/3 * CH (Properties of the centroid of a triangle).
So as x = 3
2/3 CH = 3 + 5
CH = 8 * 3/2
CH = 12.

What's the mean, median, mode, and range of 8, 10, 8, 14, 8 and 15
Answer: Mean: 10.5, Median: 9 Mode: 8 Range: 7
Step-by-step explanation
mean put the numbers in order, so 8,8,8,10,14,15 the mean is adding all numbers together and dividing by the number so 8 + 8 + 8 + 10 + 14 + 15 divided by 6 is 10.5,
median is middle so 9 since theres two middle numbers u add them both and then divide by 2
mode is the most so its 8 since 8 is there 3 times
range is the highest number and lowest number and u subtract them so 15 - 8 = 7
sorry if this is long but the answers are at the top
Answer:
Below in bold.
Step-by-step explanation:
Mean = ( 8 + 10 + 8 + 14 + 8 + 15) / 6
= 10.5.
Arrange in ascending order to find the median:
8 8 8 10 14 15
Median = mean of the middle 2 numbers
= (8 + 10)/2
= 9.
Mode = most occurring number = 8.
Range = greatest - least = 15 - 8 = 7.

Given: f(x) = -2x² +x+6
5.1 Calculate the coordinates of the turning point of f.
Answer:
[tex]\left(\dfrac{1}{4},\dfrac{49}{8}\right)[/tex]
Step-by-step explanation:
Turning points (stationary points) occur when the gradient of a graph is zero.
To find when the gradient of the graph is zero, differentiate the function, set it zero, then solve for x.
Given function:
[tex]f(x)=-2x^2+x+6[/tex]
Differentiate:
[tex]\implies f'(x)=(2)(-2)x^{2-1}+(1)x^{1-1}+6(0)[/tex]
[tex]\implies f'(x)=-4x+1[/tex]
Set the differentiated function to zero and solve for x:
[tex]\implies f'(x)=0[/tex]
[tex]\implies -4x+1=0[/tex]
[tex]\implies 4x=1[/tex]
[tex]\implies x=\dfrac{1}{4}[/tex]
To find the y-coordinate, input the found value of y into the given function:
[tex]\implies f\left(\dfrac{1}{4}\right)=-2\left(\dfrac{1}{4}\right)^2+\left(\dfrac{1}{4}\right)+6[/tex]
[tex]\implies f\left(\dfrac{1}{4}\right)=\dfrac{49}{8}[/tex]
Therefore, the turning point of the function is:
[tex]\left(\dfrac{1}{4},\dfrac{49}{8}\right)[/tex]
answers
f=1/4=49/8
Step-by-step explanation:
identify the coefficients
a=-2, b=1
substitute the coefficient into the expression
x= -1/((2x(-2))
then solve it out the equation
x=1/4
evaluate the function x =1/4
f(x) =-2x²+x+6(1/4)
f=1/4=49/8

the volume (V) of a prism is calculated as
V = Ah ( A is the area of the base and h the height )
A
A = 20 and h = 5 , then
V = 20 × 5 = 100 cm³

A = 25 and h = 4 , then
V = 25 × 4 = 100 cm³
Please help! Asap!!!
Step-by-step explanation:
mean value : the sum of the measurements of all 10 plants divided by 10 (the number of measurements).
A)
since the 2 measurement errors are compensating each other in the sum of measurements (-5 cm vs. +5 cm), the sum stays the same, the number of measurements stays the same (10), so the mean value stays the same (72 cm).
B)
the mean absolute deviation was the mean value of the absolute values of the differences of each measurement to the plant measurements.
since the mean value stayed the same, so did the difference of the 8 originally correct measurements to that mean value.
the only change is with the 2 corrected measurements.
the original (but wrong) measurement of 65 had a difference of 7 (to 72).
and now it is only 2 (70 to 72).
and the other one had a difference of 6 (72 to 78).
and now it is only 1 (73 to 72).
so, the sum of all the differences decreased by (7-2) + (6-1) = 5 + 5 = 10.
we had originally a mean absolute deviation of 8.5. the sum of all 10 original differences was therefore 8.5×10 = 85.
now this sum went down to 85-10 = 75.
and the new mean absolute deviation is 75/10 = 7.5.
