the shortest side is 6 centimeters and the length of each of the other sides is 12 centimeters each.
Let x represent the length of the shortest side of the triangle.
Two sides of the triangle are each twice as long as the shortest side. This means that the length of the two sides would be 2x.
The perimeter of a triangle is the sum of each side of the triangle.
The puzzle piece in the shape of a triangle has perimeter 30 centimeters. This means that
x + 2x + 2x = 30

Step-by-step explanation:
the equation of a horizontal line, parallel to the x- axis is

Describe and correct the error a student made when graphing y + 5 = - 3/4 (x - 8).
The student's first error was in step 1.
Step 1 should involve plotting a point at (0, 1).
Step 2 should involve plotting a point 3 units down and 4 units right from the point in step 1, at (4, -2).
Step 3, connecting the points with a line was correct.
In this question, we have been given an equation of line y + 5 = - 3/4 (x - 8)
We need to describe and correct the error a student made when graphing y + 5 = - 3/4 (x - 8).
Consider given equation.
y + 5 = - 3/4 (x - 8)
y + 5 = - 3/4 x - (-3/4) 8
y + 5 = -3/4 x + 6
y = (-3/4)x + 6 - 5
y = -3/4 x + 1
Here,
slope(m) = (-3/4)
and y-intercept (c) = (0, 1)
Therefore, the student's first error was in step 1.
Step 1 should involve plotting a point at (0, 1).
Step 2 should involve plotting a point 3 units down and 4 units right from the point in step 1, at (4, -2).

Here is an unlabeled rectangle, followed by other quadrilaterals that are labeled.
a. Select ALL quadrilaterals that are scaled copies of the unlabeled rectangle.
The quadrilateral named D, H, and E will be the scaled copies of the unlabeled rectangle.
A quadrilateral may be defined as a closed figure having four sides whereas a rectangle is a type of quadrilateral which has four sides in which any two sides are equal and the other two sides are also equal. The interior angles are 90°. The scale factor may be defined as the ratio of two dimensions such that one figure is large, and another is small. The scale factor is done due to the unpractical measurement of any figure. For example, if a figure is a scale copy of the scale factor of 6/2 it means 2 is converted into 6. Now, from the question If any figure is a scaled copy, then all dimensions must be enlarged with the same factor it means length and width both must be enlarged with the same factor. So, the unlabeled rectangle has 4 grid lengths and 2 grid widths. In H length is 8 grids and width are 4 which is the multiplication of 2 by 4 and 2. Quadrilateral D and E also follow the same.

Intelligence Quotient (IQ) scores are often reported to be normally distributed with 100.0 and standard deviation = 15.0. A random sample of 57 people is taken.
What is the probability that the mean IQ score of people in the sample is less than 987 Round your answer to 4 decimal places, if necessary.
A measure of the probability that the sample's average IQ is below 987 is 44.70 %.
Why are z-scores important?The Z-score quantifies the discrepancy between a given value and the standard deviation. The Z-score, also known as the standard score, indicates how many standard deviations a specific data point deviates from the mean.
Do z scores have p values?The Z-standard score's deviation measure, which the p-value is, can be regarded of as a percentile expression. So they do have p-values.
Given: IQ scores are frequently described as having a normal distribution with a mean of 100.0 and a standard deviation of 15.0. A sample of 57 persons is chosen at random.
Z-score = (X- μ)/σ
= (98-100)/15
= -0.1333
P value for this z score equals 0.4470 which is 44.70 %

The probability of getting heads is 1/2 which typically implies that the coin is fair. NO, procedure (b) does not give a fair coin flip outcome.
Given that, we want to generate the outcome of the flip of a fair coin, but that all we have at our disposal is a biased coin which lands on heads with some unknown probability p that need not be equal to1/2.
What is the probability?Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true.
The following procedure for accomplishing our task are:
1. Flip the coin.
2. Flip the coin again.
From here will know that the coin is first flipped twice
3. If both flips land on heads or both land on tails, it implies that we return to step 1 to start again. this makes the flip to be insignificant since both flips land on heads or both land on tails
But if the outcomes of the two flip are different i.e., they did not land on both heads or both did not land on tails , then we will consider such an outcome.
Let the probability of head = p
so P(head) = p
the probability of tail be = (1 - p)
This kind of probability follows a conditional distribution.
Therefore, the probability of getting heads is 1/2 which typically implies that the coin is fair. NO, procedure (b) does not give a fair coin flip outcome.

Mandy must to walk a distance of 24.73 units towards Mark.
Given:
Mark is standing at 35th Street and 21st Avenue, so his location can be determined using the coordinates (35,21)

We know that To rotate a figure 180 degrees, you will need to apply the rule (x, y) → (-x, -y).
Thus, The coordinates of triangle RST becomes
R (1,1) → R'(-1,-1)
S (3,4) → S'(-3,-4)
