The percent error for the batteries is 20%
Estimated defective batteries as per Saif = 12 batteries
Actual defective batteries = 10
Percent error is given by the formula:
Percent error = (E-T/E)*100
where E is the experimental value and T is the theoretical value
Substituting the values in the formula we get:
= (12-10/12)*100
= 20%
The difference between an approximate or measured value and an exact or known value is expressed as a percentage error, also known as a % error. In science, it is used to document the discrepancy between a real or accurate value and a measured or experimental value.

A pre-image includes a line segment with the length of z units in a slope of M units the pre-image is dilated by a scale factor of N. The length of a corresponding line segment in the image is blank units
The length of a corresponding line segment in the image is; Nz
How to find the Slope of the Line Segment?We know that;
Slope is the ratio of change in y-value and change in x-value.
Thus, dilation does not change the slope of any line.
Now, after dilation; M---->M
Length of line:
We know that a dilation has the effect of stretching or shrinking the line segment by the factor of N units
We are given

The probability of rolling an even number or a multiple of 3 is 3/4.
What is the probability?Probability determines the odds that a random event would happen. The probability the event takes place is 1 and the probability that the event does not happen is 0.
An even number is a number that is perfectly divisible by 2.
Probability of rolling an even number = number of sides that are even / total number of sides
Sides that are even = 2, 4, 6
Probability of rolling an even number = 3/6 = 1 / 2
Probability of rolling a multiple of 3 = number of sides that are multiples of 3 / total number of sides
Sides that are multiples of 3 = 3, 6
Probability of rolling a multiple of 3 = 2/6 = 1/2

Step-by-step explanation:
I guess you want to draw the graph.
The graph is a straight line
-6x - 20 = 4y
When x = 0:
-6(0) - 20 = 4y
y = -20/4 = -5
So, one point on the graph

When y = -2:
Plugging y = -2 into the equation:

The measures of the unknown angles are as follows:
∠DEA = ∠BEC = 60°∠AEB = ∠CED = 120°How to find the measure of angles?The measures of each angles can be found as follows:
Therefore,
∠AEB = ∠CED (vertically opposite angle)
∠DEA = ∠BEC (vertically opposite angle)
Vertically opposite angles are equal.
Therefore,
4x = 75 - x
4x + x = 75
5x = 75
x = 75 / 5
x = 15
Therefore,
∠DEA = ∠BEC = 4(15) = 60°

A certain plant grows 1 1/6 inches each week. it will rake the plant to grow 6 1/6 inches is 5 weeks 2 days.
What is the definition of time?Time is ongoing progression of existence and things that happen in what seems to be an irrevocable order from the past, present, and forward into the future. It is a quantity that is part of several measurements that are used to compare the length of events or the gaps between them, to compare how long they last, to order events, and to measure how quickly the things change in the real world or in our conscious experience. Along with the three spatial dimensions, time is frequently referred to as a fourth dimension.
Time has long been an important subject of study in religion, philosophy, and science, but defining it in a manner applicable to all fields without the circularity has consistently eluded scholars. Nevertheless, diverse fields such as the business, industry, sports, sciences, and the performing arts all incorporate some notion of time into their respective measuring systems.
A certain plant grows every week = [tex]1\frac{1}{6}[/tex] = [tex]\frac{7}{6}[/tex] inches
1 week = 7 days
Therefore in 1 day plant grows = [tex]\frac{\frac{7}{6} }{7}[/tex]
= [tex]\frac{1}{6}[/tex] inch
Now we have to calculate the number of days in which the plant grows [tex]6\frac{1}{6}[/tex] inches ≈ [tex]\frac{37}{6}[/tex] inch
Number of days = [tex]\frac{Total growth}{growth in one day}[/tex]

= [tex]\frac{37}{6}[/tex] × 6
= 37 days ≈ 5 weeks and 2 days
It will take plant 5 weeks 2 days to grow [tex]6\frac{1}{6}[/tex] inches.

What is trigonometric functions?The simplest definition of a trigonometric function is the function of an angle in a triangle, also known as a circular function. It implies that these trigonometric functions can be used to determine the relationship between a triangle's angles and sides. The fundamental trigonometric operations include sine, cosine, tangent, cotangent, secant, and cosecant.
Now given degree is 0 ,
So, we know that sin 0° = 0,
And cos 0° = 1,
⇒tanθ=sinθ/cosθ,
Here θ = 0°
⇒tan 0° = 0/1,
⇒tan 0° = 0,
Now as cot θ is the inverse of tan θ, we get,
⇒cot θ = 1/tan θ,
⇒cot 0°= 1/0,
⇒cot 0° = ∞,
Now we know that cosec θ is the inverse of sin θ, we get,
⇒cosec θ = 1/sin θ,
⇒cosec 0° = 1/0,
⇒cosec 0° = ∞
And we know that sec θ is the inverse of cos θ we get,
