A fair price for the seller's 1800 square foot house is $183.68 thousand, option B is correct
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given linear equation represents a relationship between the square footage (x) and the price (y) of houses in the neighborhood.
We can use this equation to estimate the fair price for the seller's house by plugging in the square footage (x) of the house and solving for y:
y = 0.074x + 50
y = 0.074(1800) + 50
y = 133.2 + 50
y = 183.68
Hence, a fair price for the seller's 1800 square foot house is $183.68 thousand, option B is correct

Answer:
D) 171 cm²
Step-by-step explanation:
You don’t actually need to decompose it. You could just do it as a trapezoid:
(15+23)/2=19
19x9=171
If you want to decompose it into 2 triangles and a rectangle:
10=15x9=135
1/2(3)(9)=13.5
1/2(5)(9)=22.5
135+13.5+22.5=171 also

The weight of adult female panthers in one habitat area are normally distributed with a mean of 82 pounds and a standard deviation of 9.8 pounds. What percent of the panthers weigh less than 76 pounds?
Answer:
27.09% of the panthers weigh less than 76 pounds
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Mean of 82 pounds and a standard deviation of 9.8 pounds.
This means that [tex]\mu = 82, \sigma = 9.8[/tex]
What percent of the panthers weigh less than 76 pounds?
The proportion is the pvalue of Z when X = 76. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{76 - 82}{9.8}[/tex]
[tex]Z = -0.61[/tex]
[tex]Z = -0.61[/tex] has a pvalue of 0.2709
0.2709*100% = 27.09%
27.09% of the panthers weigh less than 76 pounds

A sample of these candies came from a package containing 466 candies, and the package label stated that the net weight is 397.9 g. (If every package has 466 candies, the mean weight of the candies must exceed 397.9466
Required:
If 1 candy is randomly selected, find the probability that it weighs more than 0.8535 g. The probability is:_____
Answer:
The probability is 0.508 = 50.8%.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
Normally distributed with a mean weight of 0.8544 g and a standard deviation of 0.0525 g.
This means that [tex]\mu = 0.8544, \sigma = 0.0525[/tex]
If 1 candy is randomly selected, find the probability that it weighs more than 0.8535 g.
This is 1 subtracted by the pvalue of Z when X = 0.8535. So
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0.8535 - 0.8544}{0.0525}[/tex]
[tex]Z = -0.02[/tex]
[tex]Z = -0.02[/tex] has a pvalue of 0.492
1 - 0.492 = 0.508
The probability is 0.508 = 50.8%.

Mark multiplied a number by itself. He found a
product of 30. What is the number, rounded to the
nearest tenth?
A. 4.5
B. 5.4
C.5.5
D. 15.0
Answer:
5.5×5.5=30.5
we rounded 30.25 in nearest tenth it becomes 30
Answer:
C.] 5.5
Step-by-step explanation:
It is mentioned that the number was multiplied by the number itself.
Let's take 'x' as the number. It was multiplied by itself and the product is 30. So the equation will be:
x × x = 30
[tex]x^{2}[/tex] = 30
x = [tex]\sqrt{30}[/tex]
x = 5.47 = 5.5 (to the nearest tenth)
Work out the following.
33 + 8 x 9 =
(31 - 20) x 3 =
102 - 6 = (8-5) =
120 = (12 + 4 x 7) - 2 =
8 × 9 = 72
33 + 72 = 105
The answer is 105
2nd Equation:31 - 20 = 11
11 × 3 = 33
The answer is 33
3rd Equation:102 - 6 = 8 - 5
102 - 6 = 96
96 = 8 - 5
8 - 5 = 3
96 = 3
93 = 3 is false so therefor, this equation has no solution.
4th Equation:
102 = 12 + 4 × 7 - 2
4 × 7 = 28
102 = 12 + 28 - 2
12 + 28 = 40
102 = 40 - 2
40 - 2 = 38
102 = 38
102 = 38 is false so, it means that this equation has no solution.

B Acute
Obtuse
D Right
9514 1404 393
Answer:

Step-by-step explanation:
We can define a "form factor" for a triangle as ...
f = a² +b² -c²
where c is the longest side length. It will be interpreted as follows:
negative -- obtuse trianglezero -- right trianglepositive -- acute triangleFor this triangle, our "form factor" is ...
f = 15² +16² -21² = 225 +256 -441 = 40 . . . . a positive number
The triangle is Acute.
Andrea runs 4 miles every day, but she wants to increase her distance in order to run a 26 mile marathon. She decides to add 2 miles each day to her distance until she achieves her goal. If she starts with 6 miles today, how many miles will she have run in total, by the time she achieves her 26 mile goal? The correct answer is 176 miles.
Answer:
By the time she achieves her 26 mile goal Andrea will have run 176 miles.
Step-by-step explanation:
Since Andrea runs 4 miles every day, but she wants to increase her distance in order to run a 26 mile marathon and she decides to add 2 miles each day to her distance until she achieves her goal, to determine, if she starts with 6 miles today, how many miles will she have run in total, by the time she achieves her 26 mile goal the following calculation should be performed:
6 + 8 + 10 + 12 + 14 + 16 + 18 + 20 + 22 + 24 + 26 = X
14 + 22 + 30 + 38 + 46 + 26 = X
36 + 68 + 72 = X
36 + 140 = X
176 = X
So, by the time she achieves her 26 mile goal Andrea will have run 176 miles.
