The probability that 1 battery in a pack of 16 is defective is approximately 0.3706 or 37.06%.
How to evaluate using the binomial modelThe binomial model can be used to calculate the probability of a specific number of successful outcomes (in this case, defective batteries) in a fixed number of trials (in this case, 16 batteries) with a constant probability of success (in this case, 5%) for each trial.
The probability of 1 defective battery in a pack of 16 can be calculated using the formula:
P(X = 1) = (¹⁶C₁) × (0.05)¹ × (0.95)⁽¹⁶⁻¹⁾
where (¹⁶C₁) is the binomial coefficient, which is equal to 16.
So;
P(X = 1) = (¹⁶C₁) × (0.05)¹ × (0.95)⁽¹⁶⁻¹⁾
P(X = 1) = 16 × 0.05 × 0.95¹⁵
P(X = 1) = 0.3706
Therefore, the probability that 1 battery in a pack of 16 is defective is approximately 0.3706 or 37.06%.

3. Find (a) the net cost equivalent and (b) the single discount equivalent for a
series discount of 5/10/12.
Answer:(a) To find the net cost equivalent, we can use the formula:
Net Cost Equivalent = Original Cost / (1 - (Discount Rate / 100))
Using this formula, the net cost equivalent for a series discount of 5/10/12 is:
Net Cost Equivalent = Original Cost / (1 - (5/100)) / (1 - (10/100)) / (1 - (12/100))
(b) To find the single discount equivalent for a series discount of 5/10/12, we can use the formula:
Single Discount Equivalent = (1 - (1 - (Discount Rate1 / 100)) x (1 - (Discount Rate2 / 100)) x ... x (1 - (Discount RateN / 100))) x 100
Using this formula, the single discount equivalent for a series discount of 5/10/12 is:
Single Discount Equivalent = (1 - (1 - (5/100)) x (1 - (10/100)) x (1 - (12/100))) x 100
3. If AB = 26 and BD = 20, find AE.
In a parallelogram, opposite sides are equal in length, which can be used to calculate the length of AE. AB is equal to 26 and BD is equal to 20, so AE is equal to 6.
Is a parallelogram a rhombus?In contrast to a parallelogram, which has equal sides on both sides and diagonals that bisect each other, a rhombus has equal sides on all four sides and diagonals that cross at 90 degrees.
The length of each side is the same. A rhombus has equal opposite angles. At a 90° angle, the diagonals split in half.
In a parallelogram, opposite sides are equal in length. Therefore, we can use this fact to calculate the length of AE in the given parallelogram.
Since AB is equal to 26 and BD is equal to 20, we can set up the equation:
26 = AE + 20
Subtract 20 from both sides of the equation to solve for the length of AE:
26 - 20 = AE
6 = AE
Therefore, AE is equal to 6.

Answer: I don't have the capability to draw images. However, I can explain how to graph the equation y = x² for the interval -3≤x≤4.
To graph the equation, we can plot a set of points by substituting values of x from the given interval into the equation and solving for y.
For example:
when x = -3, y = (-3)² = 9
when x = -2, y = (-2)² = 4
when x = -1, y = (-1)² = 1
when x = 0, y = (0)² = 0
when x = 1, y = (1)² = 1
when x = 2, y = (2)² = 4
when x = 3, y = (3)² = 9
when x = 4, y = (4)² = 16
We can plot these points on a coordinate plane, and then connect them with a smooth curve.
The graph of y = x² for the interval -3≤x≤4 will be a parabola that opens upward and its vertex is located at (0,0) point.

Find the value of v that makes quadrilateral PQRS a parallelogram.
P v+38°
s 8v-56°
R 6v–72°
Q v+98°
PLEASEE HELPPPPPP ILL GIVE YOU BRAINLIESTTTTTT
Answer:
there is no value of v that makes quadrilateral PQRS a parallelogram.
Step-by-step explanation:
Hopefully this helps, may be wrong so...
A quadrilateral is a parallelogram if and only if opposite angles are equal. Therefore, in order for quadrilateral PQRS to be a parallelogram, angle P must be equal to angle S, and angle Q must be equal to angle R. From the given information, we know that:
angle P = v + 38°
angle S = 8v - 56°
angle Q = v + 98°
angle R = 6v - 72°
To find the value of v that makes quadrilateral PQRS a parallelogram, we must set angle P equal to angle S and angle Q equal to angle R:
v + 38° = 8v - 56°
v + 98° = 6v - 72°
Solving for v in the first equation:
v + 38° = 8v - 56°
-7v = -94°
v = 13.428571428571429
Solving for v in the second equation:
v + 98° = 6v - 72°
-5v = -170°
v = 34
We can see that both values of v do not match, therefore there is no value of v that makes quadrilateral PQRS a parallelogram.
A quadrilateral is a parallelogram if and only if the opposite angles are equal. In this case, the opposite angles are P and S, and Q and R.
Therefore, for the quadrilateral PQRS to be a parallelogram, we must have:
v+38° = 8v-56° and v+98° = 6v–72°
Solving the first equation for v:
v+38° = 8v-56°
38 = 7v
v = 38/7
Now we use this value of v to check if the second equation is true:
v+98° = 6v–72°
(38/7) +98 = 6(38/7) - 72
98 = -34
As we can see, the second equation is not true, so the value of v = 38/7 doesn't make quadrilateral PQRS a parallelogram.
No value of v exists that would make quadrilateral PQRS a parallelogram, as the opposite angles are not equal in this case.

Let $x$ be a real number selected uniformly at random between 100 and 200. If $\lfloor {\sqrt{x}} \rfloor = 12$, find the probability that $\lfloor {\sqrt{100x}} \rfloor = 120$. ($\lfloor {v} \rfloor$ means the greatest integer less than or equal to $v$.)
$\text{(A)} \ \frac{2}{25} \qquad \text{(B)} \ \frac{241}{2500} \qquad \text{(C)} \ \frac{1}{10} \qquad \text{(D)} \ \frac{96}{625} \qquad \text{(E)} \ 1$
The probability of successful region is =241/2500 Option b is correct.
Since √x=12, 12 ≤√x<13 and thus 144 ≤ x < 169.
The successful region is when 120 ≤ 10√x < 121 in which case 12 ≤√x< 12.1
Thus, the successful region is when
144 ≤ x < 146.41
The successful region consists of a 2.41 long segment, while the total possibilities region is 25 wide. Thus, the probability is
=2.41/25
=241/2500 (B)
In mathematics, a real number is a quantity that can be expressed as an infinite decimal expansion. In contrast to the natural numbers 1, 2, 3,..., which are derived from counting, real numbers are used in measurements of continuously varying quantities such as size and time.

A boat travels 10 miles upstream in 2 hours. Going downstream, it can travel 18 miles in the same amount of time. Find the speed of the current and the speed of the boat in still water.
The speed of the current is 7 miles per hour,
and the speed of the boat in still water is 2 miles per hour.
What is speed?The distance that an object travels in relation to the amount of time it takes to do so can be used to define speed. In other terms, it is a measurement of an object's motion's speed without direction Velocities are what we get when speed and direction are combined.
Given A boat travels 10 miles upstream in 2 hours. Going downstream, it can travel 18 miles in the same amount of time.
let the speed of the boat and current be x and y,
for downstream,
x + y = D₁/t₁
D₁ = distance traveled in downstream = 18 miles
t₁ = time taken = 2 hours
x + y = 18/2
x + y = 9 .........(1)
for upstream,
x - y = D₂/t₂
D₂ = distance traveled in upstream = 10 miles
t₂ = t₁ = time taken = 2 hours
x - y = 10/2
x - y = 5 .......(2)
adding both equations
x + y + x - y = 9 + 5
2x = 14
x = 7 miles per hour
and x + y = 9
7 + y = 9
y = 9 - 7
y = 2 miles per hour
speed of the boat is 7 miles per hour and the speed of the current is 2 miles per hour.
Hence boat's speed is 7 miles per hour and the current speed is 2 miles per hour.
