Answer:
Distance between B and C is 9.6 miles.
Step-by-step explanation:
By applying tangent rule in the given right triangle ABC,
tan(58°) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{BC}{AB}[/tex]
= [tex]\frac{BC}{6}[/tex]
1.60 = [tex]\frac{BC}{6}[/tex]
BC = 9.6 mi
Therefore, Distance between B and C is 9.6 miles.

A rectangle with sides 14 cm and 6 cm has the same diagonal as a square.
What is the length of the side of the square.
Give your answer as a surd in its simplest form.
Answer:2* square root 58
Step-by-step explanation:
To find the diagonal follow these steps:
(14^2(the side) + 6^2(the other side))square rooted
(14^2 is 196 + 6^2 is 36)
so its square root of 232 or
2*square root of 58.

In a study of speed dating, male subjects were asked to rate the attractiveness of their female dates, and a sample of the results is listed below (1 = not attractive; 10 = extremely attractive). Construct a confidence interval using a 95% confidence level. What do the results tell about the mean attractiveness ratings of the population of all adult females? 5, 8, 2, 8, 7, 6, 6, 8, 9, 9, 6, 9 What is the confidence interval for the population mean μ? <μ
Answer:
Confidence Interval = ( 5.6 < μ < 8.2 )
The interval shows that the mean attractiveness is Above average on a scale of 1 to 10
Step-by-step explanation:
Data Given : 5, 8, 2, 8, 7, 6, 6, 8, 9, 9, 6, 9
a) construct a confidence interval at a 95% confidence level
confidence interval = x ± tcritical ( s / √ n ) ------ ( 1 )
n = 12
μ (mean) = ( 5+8+2+8+7+6+6+8+9+9+6+9 ) / 12 ≈ 6.92
std ( s ) = √ 1/11 *∑( xi- X )^2
= √ 1/11 * ( 5 - 6.92)^2 + ( 8 - 6.92)^2 + ( 2 - 6.92)^2 + ( 8 - 6.92)^2 + ( 7-6.92)^2 + ( 6 - 6.92)^2 + (6 - 6.92 )^2 + ( 8 - 6.92 )^2 + ( 9 - 6.92)^2 + ( 9 - 6.92)^2 + ( 6 - 6.92 )^2 + ( 9 - 6.92 )^2
= √ 1/11 * 46.92 = 2.07
tcritical at ∝ 0.05 , df = 11 = 2.20
Back to equation 1
6.92 ± 2.2 ( 2.07 / √ 12 )
( 6.92 ± 1.31 )
Confidence Interval = ( 5.6 < μ < 8.2 )

How many degrees has (triangle)ABC been rotated counterclockwise about the origin?
Answer:
180°
Step-by-step explanation:
180
The total number of degrees in which has the triangle ABC been rotated counterclockwise about the origin is 180 degrees.
What is the rotation of the figure?The transformation of a figure around a point, either clockwise or counterclockwise, is called rotation. A figure's coordinate point changes when it rotates.
About the origin, the triangle ABC has been rotated. The new triangle A'B'C' is created as a result. In the graph below,
The vertex B' points have the same but negative coordinates,
The vertex of B of the original figure points on the same line.
The coordinate point of B is (5,8).
The coordinate points of B' is (-8,-5).
The same will goes for the A and C points of the triangle
Thus the change in coordinate point after the rotation is,
coordinates of B = (5,8)
coordinates of B' = (-5, -8)
The same will follow with A and C
This is the rotation rule of 180 degrees counterclockwise.
Therefore, The triangle ABC has been rotated 180 degrees counterclockwise in all with respect to the origin.

If Ryan rides his bike 5 miles in 3/4 of an hour, then he rides 5/3 miles in 1/4 of a hour (divide both by 3). To get to a full hour from 1/4, you need to multiply it by 4. You must do the same for 5/3. 5/3*4 is equal to 20/3.

For whole numbers between 1 and 1001, inclusive, let m be the sum of odd numbers and n be the sum of even numbers. What is the value of m−n?
Answer:
m - n = 501
Step-by-step explanation:
Remark
The first thing you have to do is find the number of odd and even numbers. This is where you have to be careful because there is a danger of being out by one.
equation
l = a + (n - 1)*d
Solution even
l = 1000
a = 2
d = 2
1000 = 2 + (n - 1)*2
998/2 = (n - 1) * 2 / 2
499 = n - 1
n = 500
Solution odd
l = 1001
a = 1
d = 2
1001 = 1 + (n - 1)*2
1000 = (n - 1)*2
1000/2 = (n - 1)2/2
500 = n - 1
501 = n
Sum Even of even numbers from 1 to 1001
Givens
a = 2
n = 500
l = 1000
Equation
Sum = (a + l ) * n / 2
Solution
Sum = (2 + 1000)*500/2
Sum = 1002 * 250
Sum = 250500
Sum of Odd numbers from 1 to 1001
a = 1
l = 1001
n = 501
Equation
sum = (a + l)*n/2
sum = (1 + 1001) * 501
sum = (1002)*501 / 2
Sum = 251001
Answer
m - n = 251001 - 250500 = 501
