Answer:
[tex]3.9 \times 10^{-11}[/tex] probability that both vehicles will have all defective fuses
Step-by-step explanation:
For each fuse, there are only two possible outcomes. Either they are defective, or they are not. The probability of a fuse being defective is independent of any other fuse. This means that the binomial probability distribution is used to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Probability of a vehicle having all defective fuses:
5% of fuses are defective, which means that [tex]p = 0.05[/tex]
A vehicle has 4 fuses, which means that [tex]n = 4[/tex].
This probability is P(X = 4). So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 4) = C_{4,4}.(0.05)^{4}.(0.95)^{0} = 0.00000625[/tex]
If 2 assembled vehicles are selected at random and independently of one another, what is the probability that both vehicles will have all defective fuses?
For each vehicle, 0.00000625 probability of having all defective fuses. For 2:
[tex](0.00000625)^2 = 3.9 \times 10^{-11}[/tex]
[tex]3.9 \times 10^{-11}[/tex] probability that both vehicles will have all defective fuses
Evaluate the following, using the distributive property. (i) – 39 × 99
(ii) (– 85) × 43 + 43 × ( – 15)
(iii) 53 × ( – 9) – ( – 109) × 53
(iv) 68 × (–17) + ( –68) × 3
(v) 26 x (-48) + (-48) x 36
(vi) (-41) x 102
(vii)(-57) x (-19) + 5
Answer:
(i) - 33 × 99
= - 3267
(iii) 53 × ( - 9) - ( - 109) × 53
= - 477 + 109 × 53
= - 477 + 5777
= + 5300
(ii) (-85) × 43 + 43 × ( - 15)
= - 3655 + 43 - 645
= - 3655 - 645 + 43
= - 4300 + 43
= - 4257

Answer:
y=1x+(-8)
Step-by-step explanation:
the product of a number and 5 is increased by 12 the result is 32 find the number
Answer:
4
Step-by-step explanation:
First, to get just the multiplication equation, we need to do,
32-12 = 20
20/5 = 4
The number is 4.
Now let's check our work.
4x5+12=32
The answer is 4.
The required number is 4.
Let the number be x.
Given, the product of x and 5 increased by 12 gives 32.
So in equation form,
[tex]5x+12=32\\[/tex]
Subtracting 12 from both the sides,
[tex]5x+12-12=32-12[/tex]
[tex]5x=20\\\\[/tex]
[tex]x=\dfrac{20}{5}[/tex]
Or, [tex]x=4[/tex]
Hence the required number is 4.

What is the slope of the following graph?
Consider the function f(x)=x−5ln(x), 1/5≤x≤10.
The absolute maximum value is =
and this occurs at x equals =
The absolute minimum value is =
and this occurs at x equals =
f(x) = x - 5 ln(x)
Get the derivative:
f'(x) = 1 - 5/x
Find the critical points:
• f'(x) = 1 - 5/x = 0 -> 5/x = 1 -> x = 5
• f'(x) is undefined for x = 0, but that's outside the domain of f(x)
Get the second derivative:
f''(x) = 5/x ^2
Check the sign of the second derivative at the critical point x = 5:
f'' (5) = 5/5^2 = 5/25 = 1/5 > 0
Since the second derivative is positive at this point, this means x = 5 is a local minimum.
Check the value of f(x) at the critical point as well as the endpoints of the given domain:
f (5) = 5 - 5 ln(5) ≈ -3.407
f (1/5) = 1/5 - 5 ln(1/5) ≈ 1.809
f (10) = 10 - 5 ln(10) ≈ -1.513
So we have
• absolute maximum = 1/5 - 5 ln(1/5) at x = 1/5
• absolute minimum = 5 - 5 ln(5) at x = 5
The absolute maximum value is f(5)=5−5ln(5), and this occurs at x equals 5
The absolute minimum value is f(1/5)= 1/5−5ln(1/5), and this occurs at x equals 1/5
Given the function f(x)=x−5ln(x),
We are to find the absolute minimum and maximum value of the function
At the turning point f'(x) = x - 5ln(x)
f'(x) = 1 - 5/x
0 = 1 - 5/x
-5/x = -1
-x = -5
x = 5
Find the second derivative of the function;
f''(x) = -5/x²
Substitute the value of x = 5 into the second derivative function to have:
f''(5) = -5/5² = 1/5
Since f''(5) = 1/5 < 0, this is the local maximum and the point x = 5 is the absolute minimum
The absolute maximum value is f(5)=5−5ln(5), and this occurs at x equals 5
The absolute minimum value is f(1/5)= 1/5−5ln(1/5), and this occurs at x equals 1/5

Answer:
k ≈ 0.03719
Step-by-step explanation:
Fill in the given numbers and solve for k.
750 = 600e^(6k)
1.25 = e^(6k)
ln(1.25) = 6k . . . . . take the natural log
k = ln(1.25)/6 . . . . . divide by 6

In her first basketball game, Charlotte scored 21 points. In the next game, she scored 15
points. By what percent did her score decrease?
ASAP
Answer:
28.57%
Step-by-step explanation:
Find the percent decrease by dividing the change in the number of points by the original number of points, then multiplying it by 100:
((21 - 15) / 21) x 100
(6 / 21) x 100
= 28.57
So, her score decreased by approximately 28.57%
