What is the area of this triangle in the coordinate plane?
Answer:
48
Step-by-step explanation:
6x8=48
Answer:
24 untits 2
Step-by-step explanation:
The following table provides a probability distribution for the random variable y. Y f(y) 1 0. 20 5 0. 30 6 0. 40 9 0. 10 (a) compute e(y). If required, round your answer to one decimal place.
The expected value of y, rounded to one decimal place, is 5.0.
Here, we have to compute the expected value E(y), we multiply each value of y by its corresponding probability and sum them up.
E(y) = (1 * 0.20) + (5 * 0.30) + (6 * 0.40) + (9 * 0.10)
Calculating the above expression:
E(y) = 0.20 + 1.50 + 2.40 + 0.90
E(y) = 5
Therefore, the expected value of y, rounded to one decimal place, is 5.0.
The expected value of a discrete random variable can be calculated as the weighted average of all its possible values, with the weights being the probabilities of each value.
In order to calculate the expected value, we will need to multiply each value by its corresponding probability and then add up these products:
E(y) = 1 (0.20) + 5(0.30) + 6 (0.40) + 9(0.10)
E(y) = 0.20 + 1.50 + 2.40 + 0.90
E(y) = 5
Therefore, the expected value of y is 5.

-0.4(x+3)=4 answer this problem
Answer:
x = - 13
Step-by-step explanation:
- 0.4(x + 3) = 4 ( divide both sides by - 0.4 )
x + 3 = - 10 ( subtract 3 from both sides )
x = - 13

5(m+2)-m=2m+3
Please I need help
Answer:
m=-7/2
Step-by-step explanation:
(5 • (m + 2) - m) - (2m + 3) = 0
2m + 7 = 0
3.1 Solve : 2m+7 = 0
Subtract 7 from both sides of the equation :
2m = -7
Divide both sides of the equation by 2:
m = -7/2 = -3.500
Answer
5(m+2)-m=2m+3
5m+10-m=2m+3
5m-2m-m=-10+3
3m-m=-10+3
2m=-7
m= -7/2
m= -3.5

16.4,1.64,1.6,16.099 greatest to least
Answer:
1.6, 1.64, 16.099, 16.4
Step-by-step explanation:
Add a 0.
1.60, 1.64, 16.099, 16.40
The ones are of lesser value because they only have one whole number, and the 16.099 is less than 16.40 because it has that 0 in front of the nines.

Explain how to determine the quadratic equation using linear factors and zeros of the graph below.
Answer:
[tex]f(x)=-x^2+11x-28[/tex]
Step-by-step explanation:
We see that the zeroes of the graphed parabola are [tex]x=4[/tex] and [tex]x=7[/tex], which are solutions to [tex]x-4=0[/tex] and [tex]x-7=0[/tex] respectively. We also observe that the parabola opens downward, so the leading coefficient is negative. By multiplying these two factors and negating the result, we can determine the actual function:
[tex]f(x)=-(x-4)(x-7)\\\\f(x)=-(x^2-11x+28)\\\\f(x)=-x^2+11x-28[/tex]
Thus, the quadratic equation represented by the graph is [tex]f(x)=-x^2+11x-28[/tex]

Answer: The area of the shaded region is 30 cm^2
Step-by-step explanation:
First, we recall the area for a rectangle and a triangle.
-Area for rectangle: A = L x W
-Area for triangle: A = 1/2 x b*h
Next, I find the area of the total region.
-12 cm x 4 cm = 48 cm^2
Then, I find the area for the non-shaded region (or the white triangle)
- A= 1/2 x 9*4
- A= 1/2 x 36
- A = 18 cm^2
Finally, I subtract the total area of the whole region from the non-shaded region ( or again white triangle)
- 48 minus 18 = 30 cm ^2

2(12+x) = 2x=24 simplify and show work
Answer:
No possible answer (unless the equal sign was supposed to be a plus sign, then see answer below)
Step-by-step explanation:
we can simplify the expression like such:
24 + 2x = 2x = 24
As you will notice 2x + 24 cannot equal 2x, or 24.
If the equals sign was a typo and was meant to be a plus sign then the answer is all real numbers.
2(12 + x) can be broken down to (2*12) + (2*x) which equals 2x + 24.
Then this equals the other side of the equation meaning that it doesn't matter what x equals the equation is always equal.

what two numbers multiply 25 and add 26
Let's set our two numbers as x and y:
When two numbers multiply 25 --> xy = 25
Add to 26 --> x + y =26
The equations:
xy = 25 <-- equation 1x + y = 26 <-- equation 2Now Solve:
Solve for y in the equation 2:
y = 26 - x <-- equation 3
Plug equation 3's value of y into equation 1
x(26 - x) = 25
-x^2 + 26x - 25= 0
x^2 - 26x + 25 = 0
(x - 1) (x -25) = 0
Thus say x = 1, then y = 25, it can be either way that x = 25 and y = 1, but our two numbers are 1 and 25
Hope that helps!
I need help with this question
Answer:
h = 16°
Step-by-step explanation:
The total angle of a straight line = 180°.
So we can say that 151° + x = 180°
180° - 151° = x
x = 29°
total angles of a triangle = 180°
∴ 118 + 29 + 2h + 1 = 180
⇒ 148° + 2h = 180°
⇒ 2h = 180° - 148°
⇒2h = 32°
⇒h = 32° ÷ 2
⇒ h = 16°

The length of a radius of a circle, measured in centimeters, is represented by the expression x 1. 5. The diameter of the circle is 925 cm. What is the value of x? Enter your answer as a decimal or mixed number in simplest form in the box.
Given that the diameter of circle = twice the radius, the value of x = 4.7.
What is the Diameter of a Circle?The diameter of a circle is a segment that divides the circle into two halves.
Diameter = 2(radius of circle).
Given:
Radius of circle = x + 1.5
Diameter = 9 2/5 = 9.4 cm
Therefore:
2(x + 1.5) = 9.4
2x + 3 = 9.4
2x = 9.4
x = 9.4/2
x = 4.7
Therefore, given that the diameter of circle = twice the radius, the value of x = 4.7.
