A set of data is normally distributed with a mean of 455 and a standard deviation of 25. What percent of the data is in the interval 405–455?
a.
47.5%
c.
68.3%
b.
49.85%
d.
34.15%
Answers
Answer:
a. 47.5%
Step-by-step explanation:
1. Find the z-score for 405: 405-455/25 = -2
2. Find the z-score for 455: 455-455/25 = 0
3. Using technology or a chart, find the percentage that corresponds with the z-scores: -2 = 0.0228 or 2.28%, AND 0 = 0.5000 or 50%
4. Find the difference between the percentages by subtracting them: 50% - 2.28% = 47.72%
5. Most of the time, the answers aren't exact, so since 47.72% is closest to 47.5%, I would say that's the answer.

Allison designs fancy boxes to fill with chocolates. The boxes are in the shape of a right square pyramid as shown, where 8y represents the
length of one side of the base of the pyramid, and 5y represents the height of one triangular face of the pyramid.
8y
The large size box must be designed to have a volume of 1,000 cubic centimeters,
Create an equation that can be used to calculate the length of the base and height of the triangular face of the box. Enter your equation in
the first response box.
Answers
The requreid equation that can be used to calculate the length of the base and height of the triangular face of the box is:
8y ≈ 8.4 cm
5y ≈ 5.8 cm
What is volume?Volume is defined as the mass of the object per unit density while for geometry it is calculated as profile area multiplied by the length at which that profile is extruded.
The formula for the volume of a square pyramid is:
V = (1/3) * base area * height
In this case, the base of the pyramid is a square with a side length of 8y, so the base area is:
base area = (8y)² = 64y²
The height of each triangular face is given as 5y, so the total height of the pyramid is 2 * 5y = 10y.
Substituting these values into the formula for volume, we get:
1000 = (1/3) * 64y² * 10y
y ≈ 1.16
Therefore, the length of the base of the pyramid is:
8y ≈ 8.4
And the height of each triangular face is:
5y ≈ 5.8 cm
So the equation that can be used to calculate the length of the base and height of the triangular face of the box is:
8y ≈ 8.4 cm
5y ≈ 5.8 cm

PLEASE ASNWER ASAP WITH WORK IN A TABLE PLEASE
Answers
Answer:
Step-by-step explanation: Given is a function as 1 divided by the quantity x minus 10 squared
Mathematically translating we get
the function
Since the function become undefined at x=10 we get
vertical asymptote is
x=10
Limit x tends to 10 of f(x) will exist since both limits are equal
This is because let x tends to 0 from left.
Then we have
f(x) =
Right limit also will be +infinity
This is because the curve is symmetrical about x=10 and hence limit would be +infinity.

Anna and Paddy take part in the same fun run.
Anna completed the fun run in 2 hours.
Her average speed was 6 kilometres per hour.
Paddy completed the fun run in 90 minutes.
(a) Work out Paddy's average speed in kilometres per hour.
Answers
Answer:
I wanna say 4.6 kmph
Step-by-step explanation:
6(average) /2(hr)=3kmph
1.20(hr) / 6 (kmph) = 4.6
If Anna and Paddy take part in the same fun run. Anna completed the fun run in 2 hours. Her average speed was 6 kilometres per hour. Paddy completed the fun run in 90 minutes. Then 4.5 km/h is Paddy's average speed
What is Equation?Two or more expressions with an Equal sign is called as Equation.
Given,
Anna and Paddy take part in the same fun run. Anna completed the fun run in 2 hours.
Her average speed was 6 kilometres per hour.
Paddy completed the fun run in 90 minutes.
We need to find paddys average speed in kilometres per hour.
Let us convert 2 hrs to minutes=120 minutes
6/120=x/90
Apply cross multiplication
90×6=120x
540=120x
Divide both sides by 120
x=4.5
Hence 4.5 kilometer per hour is the Paddy's average speed.

Trigonometry ratioGiven the following parameters
sinθ = 9/41
According to the SOH CAH TOA identity
sinθ = opposite/hypotenuse
Determine the adjacent sides
a= √41² - 9²
a = √ 1600
a = 40

The measure of angle x will be 145° so option (C) will be correct.
What is an angle?
An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
Since we lack a measurement for angular rotation, the angle is a valuable tool for measuring angular distance. For instance, a meter or an inch is a unit of measurement for linear motion.
The identical endpoint of the two rays—known as the vertex—is referenced as an angle's sides.
The angle all around the line is 360°.
The angle 165°, 50°, and x consist total of 360°.
165 + 50 + x = 360
x = 145°.
So the angle of x will be 145°.
