Given:
The graph of a trend line.
To find:
The equation of the trend line is slope intercept form.
Solution:
From the given graph it is clear that the equation of the trend line is passes through the points (0,25) and (5,50).
Slope of the line is:
[tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]
[tex]m=\dfrac{50-25}{5-0}[/tex]
[tex]m=\dfrac{25}{5}[/tex]
[tex]m=5[/tex]
The line passes through the point (0,25). So, the y-intercept of the line is 25.
Slope intercept form of a line is:
[tex]y=mx+b[/tex]
Where, m is slope and b is y-intercept.
The slope intercept from of the line is:
[tex]y=(5)x+(25)[/tex]
[tex]y=5x+25[/tex]
Therefore, the equation for the trend line in slope -intercept form is [tex]y=5x+25[/tex].
What is the total surface area of a regular heptagonal pyramid with a base side length of 7 inches and a slant height of 16 inches.
Answer: Right Regular Pyramid Surface Area = (½ * Perimeter of Base * Slant Height)
Perimeter of Base = 16 inches
Right Regular Pyramid Surface Area = (½ * 16 * 7)
= 56 square inches

c = pi times d so that would mean d divided by pi would be the diameter.
to find the radius you would then have to take the diameter and times it by 1/2 bc r = 1/2 times d

Answer:
y=x4
Step-by-step explanation:
Answer:
y-intercept = 0
Step-by-step explanation:
hello! is y = 3x - 3 proportional or non-proportional?? please help!
A proportional graph is a straight line that goes through the origin while a non-proportional graph is a straight line that doesn't go through the origin.
y = mx + b
the b represents the y-intercept, so -3 is the y-intercept in the equation y = 3x -3
therefore, the line doesn't go through the origin and is a non-proportional equation
Find n(A) for the set.
1) A = 200, 201,
202, ..., 2000)
A) n(A)= 1801
B) n(A)= 4
C) n(A)=2000
A=200,201,202.........,2000
Here, it forms an AP with common difference 1
Let the number of terms in the set be n
[tex] T_{n} = a+(n-1)d \\\\ 2000= 200+(n-1) \\\\ 200+n-1= 2000 \\\\ => n=2000-199= 1801[/tex]
Hence,n(A)=1801

Step-by-step explanation:
Which equation finds the area of a square with a side length of 5 n Superscript 4 units?
(5 n Superscript 4 Baseline) squared = 25 n Superscript 8 square units
(5 n Superscript 4 Baseline) squared = 5 n Superscript 8 square units
5 (n Superscript 4 Baseline) squared = 5 n Superscript 8 square units
5 (n Superscript 4 Baseline) squared = 10 n Superscript 8 square units

If the parent function is y = 3^x,which is the function of the graph?
Answer:
[tex]y = 3x + _ 2[/tex]
Step-by-step explanation:
The graph of y = 3^x will pass through the point (0, 1). This graph passes through the point (-3, 1); it has been shifted to the left 3 units.
A function can be translated, or shifted, to the left by adding a number to x before the function is applied; in this case, it means adding 3 to x before the base is raised to the power. This gives us
This graph has also been translated, or shifted, down 2 units. This can be done by subtracting a number from the end of the function; this gives us
Amy buy 6 tickets for a match, 3 adult and 3 children tickets. Each ticket costs £7.27. She gets £2.75 off on each children's ticket. How much does Amy finally pay for 6 tickets?
Answer:
$35.37
Step-by-step explanation:
Answer:
Amy pays £35.37 for 6 tickets
Step-by-step explanation:
since each ticket costs the same amount, we can do 6(£7.27) to find out how much she originally had to pay before she gets £2.75 off on each children's ticket
6(£7.27)=£43.62
now, since she gets £2.75 off on each children's ticket, and there are three children, to find out how much money she got off total:
3(£2.75)=£8.25
finally, we have to subtract £43.62-£8.25 to find the total amount Amy finally pays for 6 tickets
£43.62-£8.25=£35.37
so, Amy pays £35.37 for 6 tickets
The gas mileage for Peter's car is 21 miles per gallon when the car travels at an average speed of 50 miles per hour. The car's gas tank has 17 gallons of gas at the beginning of a trip. If. Peter's car travels at an average speed of 50 miles per hour, which of the following functions fmodels the number of gallons of gas remaining in the tank thours after the trip begins? 21 A. f(t) = 17 - 50T B. f(t) = 17 - 500 21 17-500 C. f(t) 17-210 50 D. f(t) = 21
Answer:
f(t)= 17- 50t/21
Step-by-step explanation:
distance covered after t hours= 50t miles
number of gal.=50t×1/21 =50t/21 gal.
f(t)=starting-consuming= remaining
= 17-50t/21
Answer:f(t)= 17- 50t/21
f(t)= 17- 50t/21
Step-by-step explanation:
distance covered after t hours= 50t miles
number of gal.=50t×1/21 =50t/21 gal.
f(t)=starting-consuming= remaining
= 17-50t/21

Answer:
θ = 76°
Step-by-step explanation:
Using the cofunction identity
sinx° = cos(90 - x)°, then
sin14° = cos(90 - 14)° = cos76°
That is θ = 76°
Answer:
in radians o= 0.13716675
Step-by-step explanation:
cos(0)=0.9906074
O= arccos(0.9906074)
O=0.13716675

which is a solutiom (x-3)(x + 9)=-27?
Answer:
x = 0, -6
Step-by-step explanation:
(0 - 3)(0 + 9) = (-3)(9) = -27
(-6 - 3)(-6 + 9) = (-9)(3) = -27
A botanist wishes to estimate the typical number of seeds for a certain fruit. She samples 41 specimens and counts the number of seeds in each. Use her sample results (mean = 54.7, standard deviation = 5.3) to find the 90% confidence interval for the number of seeds for the species. Enter your answer as an open-interval (i.e., parentheses) accurate to one decimal place (because the sample statistics are reported accurate to one decimal place).
Answer:
(53.3; 56.1)
Step-by-step explanation:
Given that:
Sample size, n = 41
Mean, xbar = 54.7
Standard deviation, s = 5.3
Confidence level, Zcritical at 90% = 1.645
Confidence interval :
Xbar ± Margin of error
Margin of Error = Zcritical * s/sqrt(n)
Margin of Error = 1.645 * 5.3/sqrt(41)
Margin of Error = 1.362
Lower boundary = 54.7 - 1.362 = 53.338
Upper boundary = 54.7 + 1.362 = 56.062

The diagonals of a quadrilateral are 12 and 10. Is
this a parallelogram rectangle? Explain your answer
Answer:
the answer is no.a parallelogram is not a rectangular but the opposite is true. the reason is a cause of parallelogram's diagonals.they might not be equal in parallelogram but in rectangular they must be equal.
Step-by-step explanation:
Answer:
If both pairs of opposite sides of a quadrilateral are congruent, then the quadrilateral is a parallelogram. So yes it is a parallelogram.
Step-by-step explanation:
Diagonals of parallelogram are not necessarily equal. This is a known property of a parallelogram. If all angles are equal, then it means its opposite angles are also equal which is a condition for a quadrilateral to be called parallelogram. If all sides are equal then, opposite sides are also equal.

The Riddle Family has a total monthly budget of $3,400. If the utilities represent 15% of the budget, then how much money is the Riddle Family spending on
utilities each month?
Answer: $510
Step-by-step explanation:
Total monthly budget = $3,400.
Percentage of total budget spent on utilities = 15%
The amount that the Riddle Family spending on utilities each month will then be:
= 15% × $3400
= 15/100 × $3400
= 0.15 × $3400
= $510
Answer:
0.15 * 3400 = $________ utilities cost per month
Multiply the monthly cost by 12.

find the measure for each angle indicated
Step-by-step explanation:
7. 180 -92 -67 =21. 180-21 = 159
8.180-144 = 36 + 94 = 130 180-130 = 50
Answer:
Step-by-step explanation:
TWO RULES:
⊳ Angles in a triangle add up to 180
⊳ Angles on a straight line also add up to 180
=================================================================
QUESTION 1
92 + 67 + x = 180
x + 159 = 180
x = 21
180 - 21 = 159
? = 159
=================================================================
QUESTION 2
144 + x = 180
x = 36
94 + 36 + ? =180
130 + ? =180
? = 50
