Brenda recorded the amount of time it took to cook potatoes in a microwave.
Are the data proportional? How do you know?
Answer:
Yes. As we can see, there is a clear pattern for what we see. For every potato, we have to cook it for an extra 5 minutes. Thus, as the data is constant in the pattern, it is proportional.
Answer:
Yes, the data is proportional. We know this because, in each scenario, the input is multiplied by 5 to produce the output.
Step-by-step explanation:
2 × 5 = 10
3 × 5 = 15
5 × 5 = 25

Please help me! It isn’t hard im just not sure how to do it .
Answer:
a. Semester 1: 86.8, Semester 2: 87
b. Semester 1: 5.7, Semester 2: 6.3
c. Semester 1 because the standard deviation of the first semester was lower than of the second. This shows that his scores were closer to the mean and therefore he was more consistent.
Step-by-step explanation: Find the mean by taking the sum of the values for each semester and divide that sum by the number of values to find the average. Do this for both semesters. Now, find the absolute value of the difference between the mean and each value of the corresponding data set. Square each if those differences and sum them up. Now divide that sum by the number of data values and take the square root. This number is your standard deviation. You will use the standard deviations to make the comparison for part c. I hope this makes sense and helps!!!!

Answer:
x = 88
Step-by-step explanation:
Becuase this is a quadrilateral, the opposite angles total 180 degrees. So, the opposite of x is 92. That would mean that x + 92 = 180. We subtract 92 from both non-variable sides to get the x by itself. 180 - 92 = 88. 92 - 92 = 0. this leaves us with X = 88
hope this helps

1) Solve for x.
(3.x - 2)°
(14x -19°
(9x+7)
Answer:
x = 12
Step-by-step explanation:
We will label the unknown interior angle of the triangle d.
14x - 19 + d = 180
14x + d = 199
d = 199 - 14x
199 - 14x + 3x + 9x + 7 - 2 = 180
199 - 2x +5 = 180
204 - 2x = 180
204 = 180 + 2x
2x = 24
x = 12

Given that A, O & B lie on a straight line segment, evaluate
x
.
Answer:
Step-by-step explanation:
It is the same way:
we know that
if A , O and B lie on a straight line segment
then
∡AOY+∡YOZ+∡ZOB=180°
so
3x+x+x=180-----> 5x=180--------> x=180/5--------> x=36°
the answer is
x=36°

The area of a trapezoid is 70.55 square feet. The length of the bases are 11.4 feet and 5.6 feet. What is the height of the trapezoid?
Answer:
8.3 feet.
Step-by-step explanation:
Area = (h/2)(a + b) where h = height and a and b are the lengths of the 2 bases.
70.55 = (h/2)(11.4 + 5.6)
(h/2)(17) = 70.55
h/2 = 70.55/17
h = (2 * 70.55) / 17
h = 8.3 feet.
The question is in the photo, that answer is not correct. At least I do not know if it is.
Answer:
Step-by-step explanation:
To get the solution lying in the shaded region,
Justify the equation with the given options,
Option (1)
[tex]\frac{x^2}{16}+\frac{y^2}{4}\leq 1[/tex]
For (1, 1),
[tex]\frac{1^2}{16}+\frac{1^2}{4}\leq 1[/tex]
[tex]\frac{1}{16}+\frac{1}{4}\leq 1[/tex]
[tex]\frac{1+4}{16}\leq 1[/tex]
[tex]\frac{5}{16}\leq 1[/tex]
True.
Therefore, point (1, 1) justifies the equation.
Option (2)
For (4, 1),
[tex]\frac{x^2}{16}+\frac{y^2}{4}\leq 1[/tex]
[tex]\frac{4^2}{16}+\frac{1^2}{4}\leq 1[/tex]
[tex]1+\frac{1}{4}\leq 1[/tex]
[tex]1\frac{1}{4}\leq 1[/tex]
False.
Therefore, point (4, 1) doesn't justify the equation.
Option (3)
For (-1, 2),
[tex]\frac{x^2}{16}+\frac{y^2}{4}\leq 1[/tex]
[tex]\frac{(-1)^2}{16}+\frac{(2)^2}{4}\leq 1[/tex]
[tex]\frac{1}{16}+1\leq 1[/tex]
[tex]1\frac{1}{16}\leq 1[/tex]
False.
Therefore, point (-1, 2) doesn't justify the equation.
Option (4)
For (2, -2),
[tex]\frac{x^2}{16}+\frac{y^2}{4}\leq 1[/tex]
[tex]\frac{2^2}{16}+\frac{(-2)^2}{4}\leq 1[/tex]
[tex]\frac{1}{4}+1\leq 1[/tex]
[tex]1\frac{1}{4}\leq 1[/tex]
False.
Therefore, point (2, -2) doesn't justify the equation.
Option (1) will be the answer.

Use OZ with VWXY
What is XY ?
A 30
B. 35
C. 40
D. 50
Answer:
Step-by-step explanation:
Chords having equal measures are equidistant from the center of the circle.
Since, VW = XY
Therefore, ZP = ZR = 15 units
A perpendicular line drawn from the center of a circle to the chord is the bisector of the chord.
VR = WR = 20 units
By applying Pythagoras theorem in ΔZRV,
ZV² = ZR² + VR²
ZV² = (15)² + (20)²
ZV = √(225 + 400)
ZV = √625
ZV = 25 units
Therefore, measure of radius ZV = 25 units.
VW = XY [Given]
Therefore, XY = 2(20)
= 40 units
Researchers at a major car company have found a function that relates gasoline consumption to speed for a particular model of car. In particular, they have determined that the consumption, C, in liters per kilometer, at a given speed, s. is given by a function C = f(s), where s is the car's speed in kilometers per hour.
Required:
a. What are the units on f'(s)?
b. Data provided by the car company tells us that f(80) = 0.015, f(90) = 0.02, and f(100) = 0.027. Use this information to estimate the instantaneous rate of change of fuel consumption with respect to speed at s = 90
Answer:
(a) The units of f'(s) is kilometer per liter
(b) [tex]\triangle = 2.22 * 10^{-4}[/tex]
Step-by-step explanation:
Given
[tex]C = f(s)[/tex]
[tex]f(80) = 0.015, f(90) = 0.02, f(100) = 0.027[/tex]
Solving (a): Unit of f'(s)
From the question, we understand that:
[tex]C = f(s)[/tex]
and
[tex]C = Litre/km[/tex] --- units
f'(s) is the inverse of C.
Hence:
i.e.
[tex]f'(s) = C^{-1}[/tex] --- units
So, we have:
[tex]f'(s) = (Litre/km)^{-1}[/tex]
[tex]f'(s) = Km/Litre[/tex]
Solving (b): Instantaneous rate of change at:
[tex]s = 90[/tex]
We have:
[tex]C = f(s)[/tex]
The change is calculated as:
[tex]\triangle = \frac{f(s)}{s}[/tex]
Substitute 90 for s
[tex]\triangle = \frac{f(90)}{90}[/tex]
Given that: [tex]f(90) = 0.02[/tex]
[tex]\triangle = \frac{0.02}{90}[/tex]
[tex]\triangle = 0.000222[/tex]
[tex]\triangle = 2.22 * 10^{-4}[/tex]
