Volume of sphere =
3 773
Density
= mass = volume
TT = 3.142
Which ball should he choose?
Dylan should choose Ball B which having lowest density.
What is volume of spere?
The volume of a sphere is calculated using the formula volume = 4/3πr³ where r is the sphere's radius.
Given that:
Ball A = diameter 7cm, mass 1.742kg
Ball B = diameter 6cm, mass 1.040kg
As we know that,
volume of a sphere =4/3πr³
1) For Ball A,
volume of a Ball A = 4/3π(3.5)³
volume of a Ball A = 179.6 cm³
given mass for Ball A is 1.742 kg = 1742 g.
So, Density = \(\frac{mass}{volume}\)
Density of Ball A will be 9.7 g/cm³.
2) For Ball B,
volume of a Ball B = 4/3π(3)³
volume of a Ball B = 113.11 cm³
given mass for Ball B is 1.040 kg = 1O40 g.
So, Density = \(\frac{mass}{volume}\)
Density of Ball B will be 9.19 g/cm³.
By comparing density of both balls,
Density of Ball A > Density of Ball B
Hence, Dylan should choose Ball B which having lowest density.

An inspector inspects a shipment of medications to determine the efficacy in terms of the proportion p in the shipment that failed to retain full potency after 60 days of production. Unless there is clear evidence that this proportion is less than 0.05, she will reject the shipment. To reach a decision, she will test the following hypotheses using the large-sample test for a population proportion:
H0 : p = 0.05, Ha : p < 0.05
To do so, she selects an SRS of 200 pills. Suppose that eight of the pills have failed to retain their full potency. The proportion 'p-hat' for the proportion of pills that have failed to retain their potency is:_____.
Solution :
It is given that :
\($H_0:p \geq 0.05$\) (Null hypothesis, \($H_0 : p = 0.05$\) is also correct)
\($H_a:p<0.05$\) (Alternate hypothesis, also called \($H_1$\))
This is a lower tailed test,
Therefore,
Sample proportion, \($\hat p = \frac{x}{n}$\)
\($=\frac{8}{200}$\)
= 0.04
And claimed proportion, P = 0.05
Significance level, \($\alpha$\) = 0.01
Therefore, calculating the statistics, we get
Standard deviation of \($\hat p, \sigma_{\hat p}=\sqrt{\frac{P\times (1-P)}{n}}$\)
\($=\sqrt{\frac{0.05\times (1-0.05)}{200}}$\)
\($\approx 0.0154$\)
Test statistic,
\($z_{observed}=\frac{\hat p -0.05}{\sigma_{\hat p}}$\)
\($=\frac{0.04 -0.05}{0.0154}$\)
\($\approx -0.65$\)
Now since this is a lower tailed test, p-value = \($P(Z < z_{observed})=P(Z < -0.65)=0.2578$\)
Rejection Criteria : Reject \($H_0$\) if p-value < α .
Conclusion : Since the p-value \($\geq \alpha$\), we fail to reject the null hypothesis. There is insufficient evidence that p is less than 0.05
The proportion 'p-hat' for the proportion of pills that have failed to retain their potency is: 0.04
The given parameters are:
H0 : p = 0.05, Ha : p < 0.05
n = 200
x = 8
p-hat is then calculated as:
\(\mathbf{\^p = \frac{x}{n}}\)
Substitute values for x and n
\(\mathbf{\^p = \frac{8}{200}}\)
Divide
\(\mathbf{\^p = 0.04}\)
Hence, the proportion is 0.04

What are two possible measures of the angle below?
The smaller angle, inside the bold lines, is -90 degrees.
The larger angle, outside the bold lines, is 270 degrees.
Angles can be measured in increments between -90° and 630°.
What angles are created when two lines cross one other?Two straight lines are considered to be intersecting if they come together at the same point. The intersection of two lines is known as the junction point. When two lines intersect, four angles are produced. The sum of the four angles is always 360 degrees.
Two straight lines that cross one other and produce right angles are called perpendicular lines. There are four right angles created when two perpendicular lines cross.
There are two types of angle connections produced when lines intersect:
Congruent opposite angles
Nearby angles are helpful
The information is
Let O (0, 0) be the origin, where the y and x axes must connect.
Thus, the angles on the four quadrants of the axis are produced.
The fourth quadrant's crossing lines create an angle that is given by For, the anticlockwise measure, A = -90°.
B = 360n - 180° for the clockwise measure, and n = 3 in this case.

Step-by-step explanation:
In Euclidean geometry, a line continues in opposite directions forever. As a result, the line will have an infinite length. How does this differ from a line in spherical geometry?
In Spherical Geometry, you can imagine a line as the sphere's great circle.
Spherical geometry uses spheres to represent points and large circles, whereas Euclidean geometry uses a plane. Angles between large circles are described in spherical geometry. The angle between the tangent lines is how we define the angle between two curves. Radians will be used to measure all angles.
A line in Euclidean geometry is undefinable. A line is a straight path with no thickness that travels in two opposing directions without coming to an end. A line has an endless number of points.

Anu was checking her emails she casually told her friend siting next to her the ratio of unread emails in my inbox is 4:1 The total number of emails is 120 what is the number of unread emails in her inbox
In a case whereby Anu was checking her emails and she casually told her friend siting next to her the ratio of unread emails in my inbox is ratio 4:1 where the total number of emails is 120 then the number of unread emails in her inbox is 96mails.
How can the unread mails be calculated?The concept that will be used here is ratio. An ordered pair of numbers a and b, represented as a / b, is a ratio if b is not equal to 0. A proportion is an equation that sets two ratios at the same value. For instance, you could express the ratio as follows: 1: 3 if there is 1 boy and 3 girls (for every one boy there are 3 girls)
The total mails in her box is 120
The we can represent the unread mails as 4x and read mails be 1x
This can be expressed as :
(4x+1x)=120mails
5x=120mails
x=120/5
x=24
This implies that the uread mails(4×24)
=96mails

Ben is tiling the floor in his bathroom the area he is tiling is 4m times 2m each tiles measures 400mm times 400mm he has 45 tiles is that enough
Answer:
No, it's not enough
Step-by-step explanation:
Given
Tilling Dimension = 4m by 2m
Tile Dimension = 400mm by 400mm
Required
Determine the 45 tiles is enough
First;
The area of the tiling has to be calculated
\(Area = Length * Breadth\)
\(Area = 4m * 2m\)
\(Area = 8m^2\)
Next, determine the area of the tile
\(Area = Length * Breadth\)
\(Area = 400mm * 400mm\)
Convert measurements to metres
\(Area = 0.4m* 04m\)
\(Area = 0.16\ m^2\)
Next, multiply the above area result by the number of files
\(Total = 0.16m^2 * 45\)
\(Total = 7.2m^2\)
Compare 7.2 to 8
Hence, we conclude that the 45 tiles of 400mm by 400 mm dimension is not enough to floor his bathroom

The formula for the volume of a pyramid is uppercase V = one-third uppercase B h Which of the following equations is equivalent to the given formula?
Step-by-step explanation:
One possible equivalent equation to the given formula is:
uppercase B = 3 uppercase V ÷ h
To see why this equation is equivalent, we can isolate uppercase B in the original formula by multiplying both sides by 3/h:
3/h * uppercase V = 3/h * (one-third uppercase B h)
Simplifying the right-hand side:
3/h * (one-third uppercase B h) = uppercase B
Substituting back in the original formula gives:
uppercase B = 3/h * uppercase V

Answer:
B. The graph of K has a greater y-intercept
D. The graph of J has a greater slope.
Step-by-step explanation:
Given a table for function J and an equation for function K, you want to know which has the greater slope, and which has the greater y-intercept.
Y-interceptThe y-intercept is the value of the function when x=0. We see from the table that y=2 corresponds to x=0 for function J.
We see from the equation for function K that the constant is 8. This is the value of y when x=0.
Function K has the greater y-intercept (8 vs. 2).
SlopeThe slope is the change in y-value when x increases by 1 unit. We see from the table that y=7 when x=1, so the change in y from x=0 to x=1 is 7-2 = 5. The slope of function J is 5.
The equation for function K has an x-coefficient of 3. This means a change in x of 1 unit will result in a change in y of 3 units. The slope of function K is 3.
Function J has the greater slope (5 vs. 3).
Additional comment
Both functions are graphed in the attachment. The y-intercepts have their points labeled. The graph with the steeper slope is the blue line, function J.

The length of a shadow of a building is 10 m . The distance from the top of the building to the tip of the shadow is 26 m. Find the height of the building. If necessary, round your answer to the nearest tenth.

What are similar triangles?
To be similar, two triangles must have the same shape, which means that their corresponding angles are equal. If the angles in two triangles are the same, they are said to be "congruent". If the angles are congruent and the sides are proportional, then the triangles are similar.
Let's call the height of the building "h". We can use similar triangles to find the height of the building.
This forms two triangles, one with the height of the building and the other with the length of the shadow.
Using the properties of similar triangles, we can set up the following proportion:
h/10 = (h+x)/26
where x is the distance from the tip of the shadow to the bottom of the building. We want to solve for h, so we can simplify and solve for h:
26h = 10 (h+x)
26h = 10h + 10x
16h = 10x
h = 10x/16
h = 0.625x
So, the height of the building is 0.625 times the distance from the tip of the shadow to the bottom of the building. We know that the distance from the top of the building to the tip of the shadow is 26 m, so the distance from the tip of the shadow to the bottom of the building is:
x = 26 - h = 26 - 0.625x
Solving for x, we get:
1.625x = 26
x = 16
Therefore, the height of the building is:
h = 0.625x = 0.625(16) = 10
So, the height of the building is 10 meters.
