Answer:
The area of this circle is 50.27
Step-by-step explanation:
The area of this circle is 50.3 units² or 16π
What is incircle?The incircle is defined as the largest circle that can be made in a triangle and is tangent to each side of the triangle.
The area of the circle is the product of the pie and the square of the radius.
The area of the circle = πr²
We are given that radius of the circle as r = 4.
Then we know that
Area = πr²
Substitute the values r = 4
π = 3.14
Area = 3.14(4)²
Area = 3.14 × 16
Area = 50.3

3 daily attendance at the water park: 346, 250, 433, 369, 422,298
Find the median, Q1, Q3,and IQR

Q1 --> 298
Q3 --> 422
IQR > 124
Step-by-step explanation:
3 daily attendance at the water park: 346, 250, 433, 369, 422,298
Find the median, Q1, Q3,and IQR
Step 1
We rearrange the given data set
250, 298, 346, 369, 422, 433
a) The Median
The formula to find the Median
= 1/2( n + 1)th term
Where n = Number of terms = 6
Median = 1/2(6 + 1)th
= 1/2(7)th term
= 3.5th term
The 3.5th term = The number between the 3rd and 4th term
3rd term = 346
4th term = 369
Hence,Median = 346 + 369/2
= 357.5
2) Q1 = First Quartile
= 1/4(n + 1)the
= 1/4( n + 1)th term
Where n = Number of terms = 6
Median = 1/4(6 + 1)th
= 1/4(7)th term
= 1.75th term
The 1.75th term = 2nd term
= 298
Q1 = 298
3) 3/4( n + 1)th term
Where n = Number of terms = 6
Median = 3/4(6 + 1)th
= 3/4(7)th term = 21/4th term
= 5.25th term
The 5.25th term = 6th term
Q3 = 422
4) Interquartile Range = Q3 - Q1
= 422 - 398
= 124

(A) [tex]2+\frac{1}{2}a[/tex]Step-by-step explanation:
You take the equations that the exercise give you:
x + y = 4x - y = aNow you clear the "y" variable in any equation you want, in this case, I'm gonna use the second equation:
x - y = a-y = a - x3. y = x - a
And now, you'll replace this third equation in the equation you didn't take (the first in this case).
x + y = 4x + (x - a) = 4x + x - a = 4Add the x variables:
2x - a = 42x = 4 + ax = (4 + a) / 2That's the answer of the exercise, but you can represent this in this form:
x = (4 + a) / 2 ↔ [tex]x = \frac{4}{2} + \frac{1}{2} a[/tex]x = (4 + a) / 2 ↔ [tex]x = 2+ \frac{1}{2} a[/tex]By this reason, the right answer is [tex]x = 2+ \frac{1}{2} a[/tex].
If CosA= sqrt 3/2, what is TanA?
Answers
Answer:
√(3)/3
Step-by-step explanation:
cos(A) = adj./hyp.
adj. = √(3) or √(3)/2
hyp. = 2 or 1
use unit circle:
hyp. = 1
adj. = √(3)/2
use pythagorean theorem c² - b² = a²
1² - (√(3)/2)² = 1 - 0.75 = 0.25
a² = 0.25
a = √(0.25)
a = 0.5
tan(A) = opp./adj.
tan(A) = 0.5/(√(3)/2)
tan(A) = 1/√(3)
rationalize
tan(A) = √(3)/3

Step-by-step explanation:
Answer:
52√3 ft²
Step-by-step explanation:
sin 60° = (√3) / 2 = h/8
h = 8 x (√3) / 2 = 4√3
cos 60° = 1/2 = a/8
a = 4 b = 15-4 = 11
area = left triangle + right rectangle
area = (4*4√3) / 2 + 11*4√3

A cell phone company expects that every 2 out of 25 cell phones will have some formof defect. At this rate, how many cell phones out of 500 will be expected to have a defect?
Answers
Answer: 40 phones
Step-by-step explanation:
The company expects that every 2 out of 25 phones will have some form of defect.
In percentage terms, this is:
= 2 / 25 * 100%
= 8%
If there are 500 phones therefore, the defected phones would still be the same percentage and the actual number would be:
= 8 % * 500
= 40 phones
A diamond ring increases in value at a rate of 5% per year. If the ring was purchased for $1200, which equation would calculate how much will it be worth in 30 years?
Would it be
A - y = 1200(1+.05)^30
B - y = 30(1+.05)^1200
C - y = .05(1+1200)^30
Answers
Answer:
A - y = 1200(1+.05)^30
Step-by-step explanation:
In this case, you need to calculate the future value and the formula to calculate that is:
FV=PV*(1+r)^n
FV=future value
PV=present value
r=rate
n=number of periods of time
The present value would be the price of the ring which is $1200. The rate is 5% per year and the number of periods of time is 30 years since you need to find the ring's worth in 30 years. Now, you can replace the values on the formula:
FV=1200*(1+0.05)^30
According to this, the answer is that the equation to calculate how much will it be worth in 30 years is: y = 1200(1+.05)^30.

Write an equation of the line, in point-slope form, that passes through the points (–7, 2) and (3, –2). Use (–7, 2) as the point (x1, y1)
Answers
Answer:
first use the equation m = y2 - y1 / x2- x1 to get the slope
m = -2 - 2 = -4
m = 3 + 7 = 10 when there is a negative for x1 it turns positive
the slope is -4/10 or -2/5
now plus the info into the point slope equation
y - y1 = m (x-x1)
this is in point slope form y - 2 = -2/5 (x + 7)
This is how to get it in y-intercept form
y -2 = -2/5x + -2.8
now add -2 on both sides to the -2.8
y = -2/5x (Slope) + -0.8 y- intercept
