Answer:
b = 45 ft
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
b² + 60² = 75²
b² + 3600 = 5625 ( subtract 3600 from both sides )
b² = 2025 ( take the square root of both sides )
b = [tex]\sqrt{2025}[/tex] = 45

x=130°
y=50°
z=130°
Step-by-step explanation:
__________
Answer:
x = 130°
y = 50°
z = 130°
Step-by-step explanation:
From the diagram, you can see that the angle given, 50° is a vertical angle to y. This means they are equal, so y = 50°.
Next, angle x, and the given 50° angle are supplementary since they form a straight line. Because of this, you get that:
50° + x = 180°
- and -
x = 130°
You can see that angle z is a vertical angle to angle x, so they are equal, which gives you z = x = 130°. --> z = 130°

Imagine opening the Triangular prism
We will have 2 triangles at the base
and 3 rectangles
The sides of the triangle : base 9in, height 3in
Area of Triangle
= [tex]\frac{1}{2} * base * height = \frac{1}{2} * 9*3 =\frac{27}{2}[/tex]
Now the rectangles
Rectangle1 with sides 9in and 15in, Area = 9*15 = 135
Rectangle 2 with sides 5in and 15in , Area = 5*15 = 75
Rectangle 3 with sides 6in and 15in, Area = 6*15 = 90
Now the total area of the prism
= [tex]\frac{27}{2}+\frac{27}{2}+135+75+90 = 27+ 135+75+ 90 = 327in^{2}[/tex]

To assess the accuracy of a laboratory scale, a reference weight known to weigh exactly 10 grams (g) is weighed repeatedly. The scale readings are Normally distributed with standard deviation sigma = 0.0002 g. The reference weight is weighed 5 times on that scale. The mean result is 10.002} g.
a) Do the 5 weighings give good evidence that the scale is not well calibrated (that is. its mean mu for weighing this weight it not 10 g)?
b) Give a 95% confidence interval for the mean weight on this scale for all possible measurements of the reference weight. What do you conclude about the calibration of this scale?
c) Compare your results in pans (a) and (b). Explain why the confidence interval is more informative than the test result.
Answers
Answer:
1.) Yes,
2.) (10.0017518 ; 10.0022482)
Step-by-step explanation:
1.) Since the average is > mean, then it shows that scale isn't well calibrated.
2.)
Sample mean = 10.002
Standard Error = σ/√n = 0.0002/√5
df = n - 1 = 5 - 1 = 4
Tcritical(0.05, 4) = 2.776
Margin of Error = Tcritical * standard error
Margin of Error = 2.776*0.0002/√5 = 0.0002482
Confidence interval :
Mean ± margin of error
Lower boundary = 10.002 - 0.0002482 = 10.0017518
Upper boundary = 10.002 + 0.0002482 = 10.0022482
(10.0017518 ; 10.0022482)
C.)
Since 10 does not fall within the interval ; then we can agree with our assertion in (1).
Confidence interval gives a range of of all possible values and not just a single point value.

PLEASE PLEASE HELP
Answers
Answer:
The speed will be "144 mph".
Step-by-step explanation:
Let the speed of the plane be "x mph".
then,
The car's speed be "x-130 mph".
According to the question,
⇒ [tex]\frac{1440}{x} =\frac{400}{x-130}[/tex]
By applying cross-multiplication, we get
⇒ [tex]1440(x-130)=400x[/tex]
⇒ [tex]1440x-187200=400x[/tex]
⇒ [tex]1440x-140x=187200[/tex]
⇒ [tex]1300x=187200[/tex]
⇒ [tex]x=\frac{187200}{1300}[/tex]

Find the area of the circle use 3.14 for pie d=6ft
Answers
Answer:
28.26 ft.²
Step-by-step explanation:
Mathematics: Explain/formula.
To find the area of a circle, multiply the radius by itself twice, then multiply the product by pi.
[tex]\pi r^2(3.14*radius*radius)[/tex]
[tex]\pi =pi[/tex]
Mathematics: Solve.
Here, the diameter is 6 ft.
To find the radius, divide the diameter by 2.
[tex]6/2=3[/tex]
[tex]radius=3[/tex]
Now, we can plug the numbers into the formula.
[tex]\pi 3^2(3.14*3*3)=28.26[/tex]
Mathematics: Conclude.
Therefore, the area of this circle is 28.26 ft.²
the area of the given circle will be 28.27 ft².
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, a circle that has a diameter of 6 ft,
Since, Radius = diameter/2
Thus,
Radius = 6/ 2
Radius = 3ft
From the formula of the area of the circle:
Area = pi* radius *radius
In our case,
Area = pi * 3 * 3
Area = 28.274
Therefore, the area of the given circle will be 28.27 ft².
