The area and perimeter of the shape is 4.65cm² and 9.5cm
What is area and perimeter of a triangle?Perimeter of a triangle = a + b +c , where a, b and c are the three different sides of the triangle. Area of a triangle = 1/2 b × h; where b is the base and h is the height of the triangle.
A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC.
Perimeter of the triangle = 3.2+ 2.0+4.3
= 9.5cm
The area of the triangle = ½bh
= 1/2 ×3.1 × 3
= 4.65 cm²

Given the following sample: 7, 9, 18, 22, 27, 29, 32, 40
1. Find the range of this data.
2. Find the interquartile range.
3. Compute the variance and the standard deviation of the data. 4. Compute the mean deviation.
5. Compute the median deviation.
Answers
The range is 33. The interquartile range is 18. The variance is 187.7143 and the standard deviation is 13.69.
The mean deviation is 7.75. The median deviation is 7.38.
How to find the range, standard deviation and mean deviation ?Range = maximum value - minimum value
Maximum value = 40
Minimum value = 7
Range = 40 - 7 = 33
The median of the lower half is (7 + 9 + 18 + 22)/4 = 14
The median of the entire set is (7 + 9 + 18 + 22 + 27 + 29 + 32 + 40)/8 = 24.5
The median of the upper half is (27 + 29 + 32 + 40)/4 = 32.
So, Q1 = 14 and Q3 = 32.
Interquartile range (IQR) = Q3 - Q1 = 32 - 14 = 18
Mean (μ) = (7 + 9 + 18 + 22 + 27 + 29 + 32 + 40)/8 = 23
Variance (σ^2) = Σ(xi - μ)^2 / (n-1)
= ((7-23)^2 + (9-23)^2 + (18-23)^2 + (22-23)^2 + (27-23)^2 + (29-23)^2 + (32-23)^2 + (40-23)^2) / (8-1)
= 187.7143
Standard deviation (σ) = √(σ^2) = √(187.7143) = 13.69
Mean deviation (MD) = Σ|xi - μ| / n
= (|7-23| + |9-23| + |18-23| + |22-23| + |27-23| + |29-23| + |32-23| + |40-23|) / 8
= 62 / 8
= 7.75
Median deviation = Σ|xi - M| / n
where M is the median.
M = (22 + 27) / 2 = 24.5
Median deviation = (|7-24.5| + |9-24.5| + |18-24.5| + |22-24.5| + |27-24.5| + |29-24.5| + |32-24.5| + |40-24.5|) / 8
= 59 / 8

Give the equation of the circle centered at the origin and passing through the point (0, 6).
Answers
The equation of circle is x² + y² = 36.
We have,
Center= (0, 0)
Passing point = (0, 6)
We know the equation of circle is
(x-h)² + (y-k)² = r²
where (h, k) be the center and r be the radius.
Now, the radius of circle is
= √(6-0)² + (0-0)²
= √36
= 6 unit

(x-0)² + (y-0)² = 6²
x² + y² = 36

Write as a percent 0.011
Answers
Answer:
1.1%
Step-by-step explanation:
To convert from percentage to decimal you simply divide by 100 so to convert from decimal to percentage you do the opposite, by multiplying by 11. In doing so, you get 1.1%. Think about it this way, if you wanted 100% of an item, you would basically just be multiplying by 1... which is 100% divided by 100. But if you wanted 50%, you would want half, or other in other words divide it in half, which is the same as multiplying by 0.50 which is 50% divided by 100
In a classroom, 100 plastic fish are in a tub. The tub is hidden from the student view. Some fish are green, and the rest are yellow.

The students go fishing, each time, picking a random fish from the tub, recording its color, and throwing the fish back in the tub.

Describe how to calculate this best estimate, and explain why your method of calculation makes sense in a way that a seventh grader my understand. Is your best estimate necessarily accurate?

The best estimate for the number of fish is that there are 82 yellow fish and 18 green fish, which you can calculate using the rule of three. This estimate is expected to be accurate.
What is the estimated number of fish of each color?This can be calculated using a rule of three as follows. Let's start with the yellow fish:
53 = 65
x = 100
53 x 100 / 65 = 82 yellow fish
Green fish:
12 = 65
x = 100
12 x 100 / 65= 18 green fish

Answers
Probability of red = \(\frac{4}{10}\) , blue = \(\frac{5}{10}\) , green = \(\frac{1}{10}\).
Meaning of probability :
Probability is calculation of how likely some event will happen. Whenever we are not sure about the outcome of an event, we can talk about the probabilities of certain outcomes—how likely they are going to happen.
The analysis of events governed by probability is called statistics.
According to the given information :
Red section = \(\frac{2}{5}\)
multiply numerator and denominator by \(2\) we get
Red section = \(\frac{4}{10}\)
Blue section = \(\frac{1}{2}\)
multiply numerator and denominator by \(5\) we get
Blue section = \(\frac{5}{10}\)
Green section = \(1\)- Red section - Blue section
Green section =\(1-\frac{4}{10} -\frac{5}{10}\)
Green section = \(\frac{1}{10}\)
Therefore Probability of red = \(\frac{4}{10}\) , blue = \(\frac{5}{10}\) , green = \(\frac{1}{10}\).

Santiago has been approved for a conventional loan which requires a 20% down payment, he has been approved for a mortgage up to $195,000. If Santiago buys a house for the max amount, how much will his down payment be? Therefore, how much house could Santiago afford? How much is Santiago's down payment? How much can Santiago spend on a house?
Answers
If Santiago has been approved for a mortgage up to $195,000 and the conventional loan requires a 20% down payment, then his down payment will be:
Down payment = 20% * $195,000
Down payment = $39,000
Therefore, if Santiago buys a house for the maximum amount he has been approved for, he will need to make a down payment of $39,000.
To calculate how much house Santiago can afford, we need to subtract the down payment from the total amount he has been approved for:
Maximum home price = Total mortgage amount - Down payment
Maximum home price = $195,000 - $39,000
Maximum home price = $156,000
Therefore, Santiago can afford a home up to a maximum price of $156,000.
To summarize:
Santiago's down payment will be $39,000.
Santiago can spend up to $156,000 on a house.
