The weight of each cookie in a batch of a certain type of commercially produced cookie follows an approximately normal distribution with a mean of 11.32 grams and a standard deviation of 0.03 grams. Approximately what percent of the cookies weigh between 11.32 and 11.35 grams?
Answers
Answer:
Around 34.14% of the cookies are between 11.32 and 11.35 grams.
Step-by-step explanation:
In a normal distribution around 68.28% of the values are around minus one to one standard deviation. In this case we want to know the percentage of values that are between zero and one standard deviation, therefore the percentage of values that are in that range is given by 68.28% / 2 , which is equal to 34.14%.
Find the volume. Round to 1 decimal place
Answers
Answer:
380.8cm³
Step-by-step explanation:
Volume of a Cylinder is: [tex]V=\pi r^2h[/tex]
'r' is the radius.
'h' is the height.
We are given a height of 9.9 cm and a diameter of 7cm.
The radius is half the diameter.
Divide 7 by 2:
[tex]7/2=3.5[/tex]
The radius is 3.5 cm.
Solve for The Volume (Using 3.14 for pi):
[tex]V=3.14*3.5^2*9.9\\\rightarrow3.5^2=12.25\\V=3.14 * 12.25 * 9.9\\V=38.465 * 9.9\\\boxed {V=380.8035}[/tex]
380.8035 ≈ 380.8
The volume of the cylinder should be 380.8cm³.

Answer:
The larger pyramid is 5,376 inches^3 greater
Step-by-step explanation:
To calculate how many inch greater the volume of the larger pyramid compared to the volume of the new smaller pyramid, what we do is to calculate the volume of both.
Mathematically, the volume of a square pyramid = area of base * height of pyramid
For the larger pyramid, length of base is 16 inches and height is 24 inches;
The area of base is L^2 since it is a square; 16 * 16 = 256 inches^2
The volume is thus 256 * 24 = 6,144 inches^3
For the smaller pyramid also, we use the same approach but this time, length of base is 8 inches and height is 12 inches
Area of base = 8 * 8 = 64 inches^2
Volume = 64 * 12 = 768 inches^3
Now how much more is the larger pyramid, that would be the volume of the larger pyramid- volume of the smaller pyramid = 6144 - 768 = 5,376 inches^3

Find the area of this shape. Correct answer will Brainliest
Answers
Answer:
As shown in picture, this is a trapezoid.
The area of a trapezoid is calculated by:
A = (base1 + base2) x height x (1/2)
To work out A, we need to find out base1, base2, and height.
base1 = YZ = [tex]\sqrt{(Zx - Yx)^{2} + (Zy - Yy)^{2} } = \sqrt{(5 - 2)^{2} + (5 - 5)^{2} } = 3[/tex]
base2 = XW =[tex]\sqrt{(Wx - Xx)^{2} + (Wy - Xy)^{2} } = \sqrt{(8 - 1)^{2} + (1 - 1)^{2} } = 7[/tex]
Otherwise, the height (distance between base1 and base2) is 4 as shown in picture.
=> A = (3 + 7) x 4 x (1/2) = 20

What is the correct equation for the line in slope-intercept form?
Answers
Answer:
y=-5x+35
Step-by-step explanation:
The equation for a line in slope intercept form is y=mx+b, where m is the slope of the line and b is the y intercept, or where the line meets the y axis.
First, we should calculate the slope of the line. The slope of any line is rise over run. We can select any two points- I will select (6,5) and (4, 15).
We see that the rise is 10 units, because 15-5=10, and the run is -2 units, because 4-6=-2. We have rise over run which is 10/-2, or -5.
So, we find that the m value is equal to -5.
The y intercept is easier to find, it is just where the line meets the y axis. The lines meets the y axis at the point (0,35) so the y intercept is 35.
Thus we have the equation of the line is y=-5x+35.
Hope this helps!

please help asap i do not like slopes
Answers
Your answer is A. (0,0)
The equation of the line is in the form y = mx + b, where m is the slope and b is the y-intercept, which is where the line cuts the y-axis.
In the line y = 4x, the ‘m’ would be 4 and the ‘+ b’ would be 0, which means that the line cuts the y-axis when y = 0.
There are only 2 answer options that have y = 0, A (0, 0) and D (4, 0). To find out which is correct, we can substitute in y = 0 into the equation y = 4x to see what the x-value would be:
y = 4x
0 = 4x
0 = x
Therefore the answer is A.
I hope this helps!
Think of y = 4x as y = 4x + 0.
If you don't have anything you're adding to
adding or subtracting to then it's 0.
Now our equation is in slope-intercept form.
We can write this as the ordered pair (0, 0).

Answers
Answer:
68 miles
Step-by-step explanation:
Distance biked on the first five days =67,60 ,69 ,68 , and 70 miles
Let the distance biked on the sixth day=x miles
We want his average for the 6 days =67 miles per day
Therefore:
[tex]Average=\dfrac{67+60+69+68+70+x}{6} \\67=\dfrac{334+x}{6}\\$Cross multiply\\67*6=334+x\\402=334+x\\x=402-334\\x=68 miles[/tex]

Which is an equation for the circle?
Answers
Answer:
Option D.
Step-by-step explanation:
From the given graph,
Center of the circle = (-4, -2)
This circle passes through a point (0, -3),
Radius of the circle = Distance between center and point (0, -3)
r = [tex]\sqrt{(0+4)^{2}+(-3+2)^{2}}[/tex]
r = [tex]\sqrt{17}[/tex]
Standard equation of the circle is,
(x - h)² + (y - k)² = r²
Where (h, k) is the center and r is the radius of the circle.
By putting the values in this equation,
(x + 4)² + (y + 2)² = (√17)²
(x + 4)² + (y + 2)² = 17
Option D. will be the answer.

Vanessa purchased a smart TV for

months after purchasing the TV, her
balance was $1,200. Seven months
after purchasing the TV, her
balance was $975. Find an equation
that models the balance y after t
months. How many months will it
take her to pay off the TV loan?
Answers
Answer:
y = 1500 - 75t
It will take her 20 months to pay off her TV loan.
Step-by-step explanation:
Vanessa purchased a smart TV for $1500 on a payment plan. After 4 months of purchasing the TV her balance was $1200 . 7 month her balance was $975. The amount she pays every month can be calculated as follows. After 4 months she paid 1500 - 1200 = $300. Her balance is $1200. Divide 300 by 4 to get $75 per month as the amount she pays every month.
1500 - 975 = 525/7 = $75 per month.
The equation to model the balance y after t months can be expressed below.
y = 1500 - 75t
where
y = balance
t = number of months
Her balance should be $0 for her to be able to pay off the TV loan.
y = 0
-1500 = -75t
divide both sides by -75
t = -1500/-75
t = 20
It will take her 20 months to pay off her TV loan.
The restrooms for the former Estabrook Hall were known to each be 117 cubic feet in volume. We are tasked with creating a 1:4 scale model of one of the rooms. For the purposes of this analysis, we'll treat the facilities like simple rectangular boxes. What is the volume of the model in cubic inches? If the model has a floor area of 117 sq. Inches, what is the height of the real facility? (include units with answer)
Answers
Answer:
1) The volume of the model is 3159 in.³
2) The height of the real facility is 61.94 ft
Step-by-step explanation:
1) The parameters given are;
Volume of the Estabrook hall = 117 ft³
Scale of model = 1:4
For the scale factor of a volume, we have;
[tex]Volume \, scale \, factor =\left (\frac{a}{b} \right )^3 = \left (\frac{1}{4} \right )^3 = \frac{1}{64}[/tex]
That is the volume of the model is 1/64 times the volume of the actual Estabrook hall restrooms or
[tex]\frac{1}{64} \times 117 \, ft^3= 1\tfrac{53}{64} \, ft^3[/tex]
∴ The volume of the model = 1.83 ft.³
1 ft.³ = 1728 in.³
∴ 1.83 ft.³ = 1.83 ft.³ × 1728 in.³/ft.³ = 3159 in.³
2) Where the model of the floor has an area of 117 in.²
Therefore, since the volume of a rectangular prism shape = Floor area × Height, we have
The height, h = Volume/(floor area) = 3159/117 = 185.8 in.
From a scale of 1:4, we have that the height of the real facility = 4 × 185.8 in.
Hence, the height of the real facility = 743.3 in = 61.94 ft.

Find the area of the the regular polygon.
Answers
Answer:
Area of regular polygon: ( About ) 442.8 units^2; Option C
Step-by-step explanation:
~ In this situation we can apply the formula 1/2 * a * P, provided a ⇒ apothem, and P ⇒ Perimeter of the shape ~
Here we are directly provided with the apothem, which makes it a whole lot easier than dividing the figure into triangles, drawing an altitude to one of the triangles, determining the tan degree of the triangle etc.
1. Given one of the sides to be 11 units, the perimeter of this hexagon would be 11 * 7, as it is implied that it is a regular polygon ⇒ Perimeter: 77 units
2. Now let us substitute the apothem and perimeter into this formula to determine the area of this regular polygon: 1/2 * 11.5 * 77 ⇒ 442.75
Area of regular polygon: ( About ) 442.8 units^2

The value of the trigonometry function sin θ in the triangle would be, 0.34.
Used the concept of trigonometry function,
sin x = Opposite / Base
Given that,
A triangle with angles is shown in the figure.
Since we know that,
sin x = Opposite / Base
Here, for the angle θ;
Opposite = 7.78
Base = 22.6
So, we get;
sin x = Opposite / Base
sin θ = 7.78 / 22.6
sin θ = 0.34
Thus, The value of the trigonometry function sin θ would be, 0.34.
