The center of a circle is at (5, –4). A point on the circle is located at (12, –4). What is the approximate circumference of the circle?
Answer:
43.98 approximately
Step-by-step explanation:
radius = [tex]\sqrt{ (5 - 12)^{2} + (-4+4)^{2} }[/tex]
= [tex]\sqrt{(-7)^{2} + 0^{2} }[/tex]
= [tex]\sqrt{49} = 7[/tex]
diameter = 14
Circumference = diameter x pi
= 14π = 43.98 approximately

x=32
Does anyone know the answer to this?!
Answer:
65°
Step-by-step explanation:
Properties of a triangle:
Triangles always have 3 sidesThe sum of the interior angles of a triangle must be equal to 180°.To solve:
Since the angles inside of a triangle must always be equal to 180, use the following formula to solve:a + b + c = 180(The variables can be assigned to any value in this situation)Since two angles are already given, replace 2 variables:a + 85 + 30 = 180Solve the equation by subtracting on both sides:a = 65The value of a is the measure of the missing angle. The problem is solved.Answer:
the missing angle is 65
Step-by-step explanation:
a whole triangle is 180
subtract the given angles from 180
180
- 85
----------
95
subtract the remaining angle

- 30

A company says its premium mixture of nuts contains 10% Brazil nuts, 20% cashews, 20% almonds, and 10% hazelnuts, and the rest are peanuts. You buy a large can and separate the various kinds of nuts. Upon weighing them, you find there are 112 grams of Brazil nuts, 183 grams of cashews, 207 grams of almonds, 71 grams of hazelnuts, and 446 grams of peanuts. You wonder whether your mix is significantly different from what the company advertises. a) Explain why the chi-square goodness-of-fit test is not an appropriate way to find out. b) What might you do instead of weighing the nuts in or- der to use a test

Nkechi wants to use a one-sample z interval to estimate what proportion of candies in a bag are red. She takes a random sample of 24 of the 80 total candies and finds that 18 of the candies in the sample are red. Which conditions for constructing this confidence interval did Nkechi's sample meet? Choose all answers that apply
Answer: The data is a random sample from the population of interest.
Step-by-step explanation: The condition is met since she randomly selected the sample from the population of interest.
The data is a random sample from the population of interests.(Option A), and individual observations can be considered independent.(Option C)
What are the conditions for valid inference about one proportion?Random sample: The sample should be taken randomly.Normal distribution of proportion: The sampling distribution of the proportion we're taking about should be normally distributed.Independent observations: Each of the observations must be independent.The missing options are:
A. The data is a random sample from the population of interests.
B The observed counts of successes and failures are both sufficiently large.
C. Individual observations can be considered independent.
For this case, we're given that the sample was random.
Sample size is 24,which is not sufficiently large (usually we take > 30 as sufficiently large size).
Also, each candle was independent for being red colored.
Thus, the data is a random sample from the population of interests.(Option A), and individual observations can be considered independent.(Option C)

Answer:
Volume of cuboid = 1,386 inch³
Step-by-step explanation:
Given:
Length of cuboid = 14 inch
Width of cuboid = 9 inch
Height of cuboid = 11 inch
Find:
Volume of cuboid
Computation:
Volume of cuboid = Length of cuboid x Width of cuboid x Height of cuboid
Volume of cuboid = 14 inch x 9 inch x 11 inch
Volume of cuboid = 126 inch² x 11 inch
Volume of cuboid = 1,386 inch³
