Given quadrilateral DEFG is an isosceles trapezoid. Find DE.
A-10
B-3
C-12
D-11
The measure of DE is 10 from the given figure
Since the given trapezoid is an isosceles trapezoid, this shows that two of the sides will be equal. According to the given diagram, we can say that:
DG = EFGiven the following parameters
DG = 2x + 5
EF = 3x + 2
2x + 5 = 3x + 2
Collect the like terms
2x - 3x = 2 - 5
-x = -3
x = 3
Get the measure of DE
DE = 4x - 2
DE = 4(3) - 2
DE = 12 - 2
DE = 10
Hence the measure of DE is 10 from the given figure

The probability density function of the time to failure of an electronic component in a copier (in hours) is f(x) for Determine the probability that
a. A component lasts more than 3000 hours before failure.
b. A component fails in the interval from 1000 to 2000 hours.
c. A component fails before 1000 hours.
d. Determine the number of hours at which 10% of all components have failed.
The question is incomplete. Here is the complete question.
The probability density function of the time to failure of an electronic component in a copier (in hours) is
[tex]f(x)=\frac{e^{\frac{-x}{1000} }}{1000}[/tex]
for x > 0. Determine the probability that
a. A component lasts more than 3000 hours before failure.
b. A componenet fails in the interval from 1000 to 2000 hours.
c. A component fails before 1000 hours.
d. Determine the number of hours at which 10% of all components have failed.
Answer: a. P(x>3000) = 0.5
b. P(1000<x<2000) = 0.2325
c. P(x<1000) = 0.6321
d. 105.4 hours
Step-by-step explanation: Probability Density Function is a function defining the probability of an outcome for a discrete random variable and is mathematically defined as the derivative of the distribution function.
So, probability function is given by:
P(a<x<b) = [tex]\int\limits^b_a {P(x)} \, dx[/tex]
Then, for the electronic component, probability will be:
P(a<x<b) = [tex]\int\limits^b_a {\frac{e^{\frac{-x}{1000} }}{1000} } \, dx[/tex]
P(a<x<b) = [tex]\frac{1000}{1000}.e^{\frac{-x}{1000} }[/tex]
P(a<x<b) = [tex]e^{\frac{-b}{1000} }-e^\frac{-a}{1000}[/tex]
a. For a component to last more than 3000 hours:
P(3000<x<∞) = [tex]e^{\frac{-3000}{1000} }-e^\frac{-a}{1000}[/tex]
Exponential equation to the infinity tends to zero, so:
P(3000<x<∞) = [tex]e^{-3}[/tex]
P(3000<x<∞) = 0.05
There is a probability of 5% of a component to last more than 3000 hours.
b. Probability between 1000 and 2000 hours:
P(1000<x<2000) = [tex]e^{\frac{-2000}{1000} }-e^\frac{-1000}{1000}[/tex]
P(1000<x<2000) = [tex]e^{-2}-e^{-1}[/tex]
P(1000<x<2000) = 0.2325
There is a probability of 23.25% of failure in that interval.
c. Probability of failing between 0 and 1000 hours:
P(0<x<1000) = [tex]e^{\frac{-1000}{1000} }-e^\frac{-0}{1000}[/tex]
P(0<x<1000) = [tex]e^{-1}-1[/tex]
P(0<x<1000) = 0.6321
There is a probability of 63.21% of failing before 1000 hours.
d. P(x) = [tex]e^{\frac{-b}{1000} }-e^\frac{-a}{1000}[/tex]
0.1 = [tex]1-e^\frac{-x}{1000}[/tex]
[tex]-e^{\frac{-x}{1000} }=-0.9[/tex]
[tex]{\frac{-x}{1000} }=ln0.9[/tex]
-x = -1000.ln(0.9)
x = 105.4
10% of the components will have failed at 105.4 hours.
if (8^9)^p=8^18what is the value of p
Answer:
[tex]\huge\boxed{p=2}[/tex]
Step-by-step explanation:
In order to simplify this equation [tex](8^9)^p = 8^{18}[/tex], we have to use basic exponent rules.
Exponent rules tell us that [tex](a^b)^c = a^{b\cdot c}[/tex].
We have [tex](8^9)^p[/tex], so this means that it's equivalent to [tex]8^{9 \cdot p}[/tex] or just [tex]8^{9p}[/tex].
Now, we have [tex]8^{9p}=8^{18}[/tex]
Let's just focus on the exponents for now.
Since we know that in order for [tex]8^{9p}[/tex] to be equivalent to [tex]8^{18}[/tex], the exponents must be the exact same. So, [tex]9p=18[/tex].
We can find p by divide both sides by 9.
[tex]p = 2[/tex]

Answer:
x = 1, XZ = 48
Step-by-step explanation:
So you already have the diagram with the number labeled,
4(x + 5) and 2(x + 11)
We know that Y is the midpoint between X and Z so we know that XY = YZ:
4(x + 5) = 2(x + 11)
Let's solve the equation for x:
4x + 20 = 2x + 22 (Distributive Property)
Subtract 20 from both sides:
4x = 2x + 2
Subtract 2x from both sides:
2x = 2
Divide both sides by 2:
x = 1
So now we know that x = 1, we want to find XZ:
XZ = 4(x + 5) + 2(x + 11)
We can plug in x (1):
XZ = 4(1 + 5) + 2(1 + 11)
Simplify:
XZ = 4(6) + 2(12)
XZ = 24 + 24
XZ = 48

The division of the number 90 in the ratio 1:4:5 will be 9:36:45.
What are ratios and proportions?An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. The numerical relationship between two values demonstrates how frequently one value contains or is contained within another.
Given that the number 90 is divided in the ratio 1:4:5. The division will be done as below,
x + 4x + 5x = 90
10x = 90
x = 90 / 10
x = 9
The ratio will be,
1:4:5 = 9 : ( 9 x 4 ) : ( 9 x 5 )
1:4:5 = 9: 36: 45

Answer:
Heloo
Step-by-step explanation:
Simplifying
3x + 21 = 6x + -60
Reorder the terms:
21 + 3x = 6x + -60
Reorder the terms:
21 + 3x = -60 + 6x
Solving
21 + 3x = -60 + 6x
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-6x' to each side of the equation.
21 + 3x + -6x = -60 + 6x + -6x
Combine like terms: 3x + -6x = -3x
21 + -3x = -60 + 6x + -6x
Combine like terms: 6x + -6x = 0
21 + -3x = -60 + 0
21 + -3x = -60
Add '-21' to each side of the equation.
21 + -21 + -3x = -60 + -21
Combine like terms: 21 + -21 = 0
0 + -3x = -60 + -21
-3x = -60 + -21
Combine like terms: -60 + -21 = -81
-3x = -81
Divide each side by '-3'.
x = 27
Simplifying
x = 27
Answer:
x = 27Step-by-step explanation:
3x + 21 = 6x - 60

Which equation describes the line whose x-intercept is (4,0) and whose y-intercept is (0,-3)?
Answer:
[tex]y = \frac{3}{4}x - 3[/tex]
Step-by-step explanation:
In slope intercept form y = mx + b
We have the y intercept already so our equation becomes y = mx -3. Now we need to figure out the slope, we do this by subtracting the y values from both points and the x values from both points:
-3 - 0 = -3
0 - 4 = -4
Slope = -3/-4 the negatives cancel and now we have 3/4 as the slope.
Now the equation is y = 3/4x -3
[tex] y \: = \: \frac{3}{4} x \: - 3[/tex]
Double checking by inputting values such as x = 0 we now get (0, -3) which is correct and if the x-intercept is 4 then it should give us a y value of 0 which = (4,0). Yep! This is the correct linear equation for the line described
