Answer:
The true percentage actually differ from 85%, 10%, and 5%chi-square statistic. = 5.0294Step-by-step explanation:
85% of fasteners = conforming
10% of fasteners = downgraded
5% of fasteners = scrap
In a sample size of 500 fasteners
410 = conforming , 55 = downgraded,
The true percentage actually differ from 85%, 10%, and 5% as shown below
Observed Expected
conforming 410 500*0.85 = 425
Downgraded 55 500*0.10 = 50
Scrap 35 500 * 0.05 = 25
Test statistic
determine the test statistic
= [ (410 - 425)2 / 425 + (55 -50)2 / 50 + (35 - 25)2 / 25 ]
chi-square statistic. = 5.0294

10. Cassandra needs 2 meters of string
C. 150 milliliters
D. 1,500 mililiters
centimeters of string do
Answer: D 1,500
Step-by-step explanation:
Because there is 2,000 milliliters in 2 liters, so if we do 2,000 - 500 we get 1,500 left
Answer:
Both A and D
Step-by-step explanation:
Because 500 milliters is half of one liter which makes the total 1.5 liters or 1500 mililliters

Part D Some of the measurements of the triangular prism with a right triangle base are shown. What is the length of the hypotenuse of the base?
Answer:
Hypotenuse = 5.7 cm
Step-by-step explanation:
Since the base is a right triangle, we would apply pythagorean theorem to find the length of the hypotenuse of the triangular base.
Pythagorean theorem is given as: c² = a² + b²,
Where,
c = hypotenuse
a = 4 cm
b = 4 cm
Substitute
(Hypotenuse)² = 4² + 4²
Hypotenuse = √32
Hypotenuse = 5.65685425
Hypotenuse = 5.7 cm (nearest tenth)
User averysmartperson is helping with this question.
Answer:
[tex]x^2 + (y-60)^2 = 30,625[/tex]
Step-by-step explanation:
There are 42 carts, so there is 42 spaces in between them; if one of those spaces are 25pi/3 feet long, then 42 of them would be 25*42*pi/3 = 350pi (Perfect! no fractions)
350pi is the circumference. Now if we plug that into the circumference equation we get:
C = 2pi*r
350pi = 2pi*r
Divide both sides by pi to get rid of it
350 = 2r
Divide both sides by 2
r = 175 feet
So the new equation to graph it is:
x^2+y^2 = 175^2 = 30,625
We also know that the center of the Ferris wheel has to be at least 60 feet from the ground. Since the radius is more than that, a good bit of the Ferris wheel has to be underground OR we can make it higher (keyword: at least) if we want it to be above ground. I'll do the equation for underground since it more closely represents the question.
subtracting a number from y, shifts the graph up that much so:
[tex]x^2 + (y-60)^2 = 30,625[/tex]
I can't really draw it electronically but I can graph it:

Leonard wrote the sequence of numbers below. 9, 15, 21, 27,... Which expression did be use to form the sequence, where n is the term number?
A 3n + 3
B 3n - 3
C 6n+3
D 6n-3
Answer:
I think they took 3 * 3 is equals to 9
3 * 5 equals to 15
3 * 7 equals to 21
and 3 * 9 equals to 27.
Step-by-step explanation:
can can you realise that they skipped 3 * 4 3 * 6 and 3 * 8 and the difference between 9 and 15 is 6 meaning there's a gap of 6 at each sequence so I guess my answer is 3 and + 3 if it's not if this is not the answer please tell me if it is not matching with your book tell me so that i can ask the people around me. answer 3n + 3

[tex]y=-\frac{1}{5} x-1[/tex]
Step-by-step explanation:
Hi! Welcome to brainly!
So slope intercept form - y = mx + b
where m = slope and b = y intercept
First lets find the y intercept
The y intercept is at (0,-1)
B would equal the y value of the y intercept so b = -1
now lets find the slope
To do so we can pick 2 points on the line and use the slope formula
[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]
the points can vary but i chose the points (5,-2) and (10,-3)
having found the points we plug them into the formula
[tex]m = \frac{-3-(-2)}{10-5} \\-3-(-2)=-1\\10-5=5\\m=-\frac{1}{5}[/tex]
now that we have found all of the information we plug the values into the equation and get that the answer is
[tex]y=-\frac{1}{5} x-1[/tex]
find the volume of the cone Diameter:10 m and Height:10m
Answer:
V = 260.2 m^3
Step-by-step explanation:
The area of the circular base is (pi)(r)^2, where r is the radius and half the diameter.
In this case the volume of the cone is V = (1/3)(pi)(5 m)^2*(10 m) = 260.2 m^3
Answer: 262

The area of a triangle is 36 m2 and the height is 9 m. What is the length of the corresponding base?
Answer:
base = 8 m
Step-by-step explanation:
base = (2* area) ÷ height

Find the lateral area of this cone.
Leave your answer in terms of pi
15cm
8cm
Answer:
lateral surface area of cone =
[tex]\pi rl[/tex]
where, l = slant height, and r = radius
then
[tex]l.a = \pi \times 8 \times 17[/tex]
[tex]l.a = 136\pi[/tex]
The lateral area of this cone will be 136 π. Lateral area is found as the product of pi ,radius and slant height.
What is a cone?It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.
lateral area of this cone is found as;
L=πrl
L=π×8×17
L=136π
Hence,the lateral area of this cone will be 136 π.

Classify the triangle
Answer:
This triangle is an isosceles acute
Step-by-step explanation:
First lets define each classification
scalene - no equal sides
isosceles - two equal sides
equilateral - all equal sides
acute - all angles have a measure of less than 90 degrees
right - has a right angle (90 degree angle)
obtuse - has an angle that has a measure of more than 90 degrees
Now lets classify
The triangle has two equal sides (indicated by the little line on the top and bottom side) therefore it is an isosceles triangle
We know its an acute triangle because the one angle given is not a right angle nor a obtuse angle meaning that the other two angles are going to have a measure of less than 90 degrees
So we can conclude that this is an isosceles acute triangle
1. Anvi borrowed $5,000 from a bank at a flat interest rate of 11% per year for a 3-year
period. How much interest does she have to pay the bank at the end of 3 years? (2dp)
Answer:
He will have to pay $1,650 in interest at the end of 3 years.
Step-by-step explanation:
This is a simple interest problem.
The simple interest formula is given by:
[tex]E = P*I*t[/tex]
In which E is the amount of interest earned, P is the principal(the initial amount of money), I is the interest rate(yearly, as a decimal) and t is the time.
After t years, the total amount of money is:
[tex]T = E + P[/tex]
Anvi borrowed $5,000 from a bank at a flat interest rate of 11% per year for a 3-year period.
This means that [tex]P = 5000, I = 0.11, t = 3[/tex]
How much interest does she have to pay the bank at the end of 3 years?
[tex]E = P*I*t = 5000*0.11*3 = 1650[/tex]
He will have to pay $1,650 in interest at the end of 3 years.

Answer:
4.67 inches
Step-by-step explanation:
Shanna is planning a trip from Dallas, Texas, to San Diego, California.
She will travel about = 1,400 miles
The scale of a map is 300 miles = 1 inches
The trip of 1,400 miles = [tex]\frac{1400}{300}[/tex]
= 4.66666 inches ≈ 4.67 inches
Her trip is 4.67 inches far on the map.
A baker has 6 pounds of sugar. He divides into 3 containers. He then uses 1 container to bake pies.
Step-by-step explanation:
If the question is how much sugar contains pie, then do it like this:
6:3=2
So in one container you have 2 pounds of sugar. And if you use 1 container for a pie you will use : 2 pounds of sugar for pie.
If question is how much sugar does he have after that, it would be:
6-2=4 pounds of sugar or
3-1= 2 containers of sugar
