Which of the following equations describes the line shown below? Check all
that apply. (-3,-6)(9,3)
Answers
Answer:
C and D
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (- 3, - 6) and (x₂, y₂ ) = (9, 3) ← 2 points on the line
m = [tex]\frac{3+6}{9+3}[/tex] = [tex]\frac{9}{12}[/tex] = [tex]\frac{3}{4}[/tex]
Using (a, b ) = (9, 3 ) , then
y - 3 = [tex]\frac{3}{4}[/tex] (x - 9) → C
Using (a, b ) = (- 3, - 6 ), then
y - (- 6) = [tex]\frac{3}{4}[/tex] (x - (- 3) ) , that is
y + 6 = [tex]\frac{3}{4}[/tex] (x + 3) → D

The ages of trees in a forest are normally distributed with a mean of 25 years and a standard deviation of 5 years.
Answers
Complete question is in comment section :
Answer:
68%
Step-by-step explanation:
Mean = 25
Standard deviation = 5
The percentage of trees between 20 and 30
20 trees = 1 standard deviation below the mean ; mean - 1(standard deviation)
25 - 5 = 20
30 trees = 1 standard deviation above the mean ;
Mean + 1(standard deviation) ;
25 + 5 = 30
This means, 20 and 30 lies ±1 standard deviation from the mean which according to the empirical rule is 68%

A square has an area of 227 in^2?
Answers
Answer:
s = √227 in
Step-by-step explanation:
A = s²
Where,
A = Area of a square
s = side length of the square
Find the side length of a square with area of 227 in²
A = s²
227 in² = s²
Find the square root of both sides
√227 in² = √s²
√227 in² = s
s = √227 in
Answer:
s = √227 in

A farmer has an equal number of cows in 3 different fields on his farm. Which choice could be the total number of cows
Answers
Options :
112
178
207
206
Answer:
207
Step-by-step explanation:
Given that:
Number of cows in each field = x
Number of fields = 3
Hence, total number of cows would be :
Number of cows per field * number of fields
Total number of cows = 3x
Therefore,
The total number of cows must be a multiple of 3 : as the total would be a while number.
From the options given, the only possible value for the total Number of cows is 207 as it is the only number which is a multiple of 3 in the options given.
207 = 3x
x = 207 / 3
x = 69

Every day, Bridgette's burrito stand uses 7/10 of a bag of tortillas. How many days will 6 3/10 bags of tortillas last?
Answers
Answer:
Number of days bags of tortillas will last = 9 days
Step-by-step explanation:
Total bags of tortillas =6 3/10
Bag of tortillas used per day = 7/10
How many days will 6 3/10 bags of tortillas last?
Number of days bags of tortillas will last = Total bags of tortillas / Bag of tortillas used per day
= 6 3/10 ÷ 7/10
= 63/10 × 10/7
= 63*10 / 10*7
= 630/70
= 9
Number of days bags of tortillas will last = 9 days

A track is 400 yards around how many full laps does tyler need to run if he wants to run atleast 2 milies
Answers
Answer:
17.6 laps
Step-by-step explanation:
Total distance to be covered = 2 miles
distance coved in each lap = 400 yards
We know that 1 mile = 1760 yards
therefore, 4 miles will make = 4×1760
= 7040 yards.
Number of laps to be taken
= Total distance to be covered ÷ distance coved in each lap
= 7040/400 = 17.6 laps
Therefore, it would take 17.6 laps to cover a distance of 4 miles if lap were 400 yards.

Which statement describes the behavior of the function around the vertical asymptotes?
Answers
Answer:
Its B
I only answered it on the test and it said it was right
The vertical asymptote concept is used to solve this question. First, I explain the concept, and then, we use it to solve the question.
Using this, the correct option is the second.
Vertical asymptote:
A vertical asymptote is a value of x for which the function is not defined, that is, it is a point which is outside the domain of a function;
In a graphic, these vertical asymptotes are given by dashed vertical lines.
In this question:
Vertical asymptoes at [tex]x = -3[/tex] and [tex]x = 3[/tex]
At x = -3
To the left(x < -3), goes to plus infinite. To the right(x > -3), goes to negative infitite, so:
[tex]\lim_{x \rightarrow -3^{-}} = \infty, \lim_{x \rightarrow -3^{+}} = -\infty[/tex]
At x = 3
To the left(x < 3), goes to plus infinite. To the right(x > 3), goes to negative infinite, so:
[tex]\lim_{x \rightarrow 3^{-}} = \infty, \lim_{x \rightarrow 3^{+}} = -\infty[/tex]
Left and right have the same limits both at x = -3 and x = 3, and thus, they behave in the same manner, and the second option is correct.

What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The three consecutive odd numbers are x + 3, x + 5, and x + 7. The sum of these numbers cannot be greater than 201. Then the inequality is given as,
x + 3 + x + 5 + x + 7 ≤ 201
Simplify the inequality, then we have
x + 3 + x + 5 + x + 7 ≤ 201
3x + 15 ≤ 201
3x ≤ 186
x ≤ 62
The range value of the variable 'x' will be less than or equal to 62.

A 10 ft by 10 ft square garden contains a large walking path through the diagonal what is the area of the walking path shown in the grey above
Answers
Answer:
64 ft^2
Step-by-step explanation:
Area of shaded part = area of a square = 2 x area of a triangle
area of a square = length^2
10^2 = 100 ft^2
Area of a triangle = (1/2) x base x height
1/2 x 6 x 6 = 18 ft^2
area of shaded part = 100 - 2x 18 = 64 ft^2

Answers
Answer: Loss of 3 yards
Step-by-step explanation:
The overall gain or loss of all 5 plays will be gotten by adding all the results of the plays given and this will be:
= 7 + 2 - 5 - 23 + 16
Collect like terms
= 7+2+16-5-23
= 25 - 28
= -3
The overall loss of all 5 plays will be -3 yards or loss of 3 yards
