a. The mean mass of Ca in the solid sample is 0.3784 g with a standard deviation of 0.0014 g and a relative standard deviation of 0.37%.

b. The average percent weight of Ca in the solid sample is 8.73% with a standard deviation of 0.32%. The 95% confidence interval for the percent weight of Ca is 8.09% to 9.37%.

To calculate the mean mass of Ca in the solid sample, we sum up the individual measurements and divide by the total number of measurements. Adding the given values, we get a sum of 1.8912 g. Dividing this sum by 5 (the number of measurements) gives us the mean mass of Ca as 0.3784 g.

To calculate the standard deviation, we subtract the mean from each individual measurement, square the differences, sum up the squared differences, divide by the total number of measurements minus 1 (in this case, 4), and take the square root of the result. This gives us a standard deviation of 0.0014 g.

The relative standard deviation (RSD) is calculated by dividing the standard deviation by the mean and multiplying by 100 to express it as a percentage. In this case, the RSD for the mass of Ca is 0.37%.

The shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

What is a normal distribution?

A normal distribution is a function on some random variables, which represent the set of all those random variables in a symmetrical bell shape about the mean value.

It shows that the probability of occurrence of some data which is distributed over a function is more at or around the mean.

It is also known as probability distribution curve.

The normal distribution has two parameters:

What is the shape of the normal distribution?

The normal distribution curve is at it's peak at the mean value. This shows that the probability of occurrence of the data or value is more concentrated or distributed about the mean. It is also symmetric about the mean. As we more further from the mean, we see that the normal distribution curve gradually decreases showing that the probability of occurrence of the data or the values decreases. The shape that this curve forms is like a bell-shaped. So the shape of normal distribution is bell shape.

Hence, the shape of the normal distribution is bell shape and it is also symmetrical from the left and right sides about the origins (mean).

Answer:

Choice A, 20(3n-m)

Step-by-step explanation:

First, lets combine like terms for the question 54n - 20m + 6n,

60n - 20m.

Next, lets rule out the choices that are visibly wrong. This includes Choice B, because it wouldn't equal what is above and Choice C, as it ignores unlike terms.

Now, it is down to Choices A and D. Let's use the distributive property to simplify these options.

Choice A:

20(3n-m)

60n-20m

Choice D:

20(m-3n)

20m-60m

With this, it can be concluded that the correct answer is Choice A since it equals 60n-20m, which is equal to the original question when like terms are combined.

We substitute

ANSWER

The slope is -6/13

Answer:

the first option

Step-by-step explanation:

(f-g)(x) simply means to subtract both expressions. really literally.

and we go through it power by power of x.

the highest power/exponent of x is 3 (x³). only f(x) has one.

so, -7x³ is the first part of f-g.

next is x².

11x² - 6x² = 5x², which is the second part of f-g.

next is x.

-8x - (-14x) = -8x + 14x = 6x, which is the third part of f-g.

next is x⁰ (in other words, no x, just a constant).

4 - (-3) = 4 + 3 = 7, which is the 4th part of f-g.

we have no x to the power of -1 or -2, so we have -3

0 - (-4x‐³) = 4x‐³, which is the last part of f-g.

so, it is clearly the first answer option.

0.0000679 in scientific notation

\(6.79 \times 10 {}^{ - 5} \)

Answer: 6.79×10^-5

Step-by-step explanation:

In order to write the given value in scientific notation, we have to bring the decimal point after the first non-zero digit.

So it will become 6.79

Now for the zeros that have been removed we represent them in the form 10^-5.

And it is -5 because we have removed the zeros from the left side of the value. The 10^-5 indicates that we have to move "five points" to the "left side" to get the original value again.

So it is first, 0.0000679

(we make the decimal point jump across four zeros to the right side and then across the 6 which is the first non zero digit, that is 5 jumps in total as indicated by the 10^-5)

Then it becomes:

6.79×10^-5

Answer:

C because X values can't be repeated

Step-by-step explanation:

Gibbs phase rule: F = C - P + 2, where F is degrees of freedom, C is components, and P is phases.

Starting with the expression for the Gibbs free energy of phase r, Gr = ∑(μirNir), where μir is the chemical potential of substance i in phase r and Nir is the number of moles of substance i in phase r. The chemical potential is a homogeneous function of temperature, pressure, and mole numbers.

Differentiating the expression for Gibbs free energy with respect to temperature, pressure, and mole numbers, we can obtain partial derivatives and use them to derive relationships between variables.

Using these relationships and considering the equilibrium conditions, we can derive the Gibbs phase rule: F = C - P + 2, where F is the number of degrees of freedom, C is the number of components (chemically independent substances), and P is the number of phases in the system.

When chemical reactions between different molecules are included, the phase rule can be generalized to account for additional constraints and variables arising from the stoichiometry of the reactions and the conservation of atoms.

Answer:

D

Step-by-step explanation:

To solve this question we can use the area formula for an octagon.

It is as follows:

A=2(1+√2)a^2

where "A" is the total area and "a" is the length of a side.

Plug in our side length a=10.4

A=2(1+√2)10.4^2

≈522.24268

Alternatively, you can split the octagon into 8 equal triangles.

The base of each triangle would be 10.4 and the height would be 12.5 since opposite sides are 25 feet apart. (25/2)

The area of a triangle would then be:

A=1/2bh

where "b" is base and "h" is height

A=125*10.4*1/2

=65

Since there are 8 we multiply that by 8 for the area of an octagon

65*8=520

The area of the octagon base is 520 square feet.

I'll use this value to do my calculations as it is more exact.

Now, using this area, we need to find the volume of the pool we are meant to fill.

To do this, we simply multiply the area of the base by the height.

520*3=1560

Now, we know that the volume of the pool is 1560 cubic feet.

Each cubic foot takes 7.5 gallons to fill.

1560*7.5=11700

Therefore, the pool takes 11700 gallons of water to fill.

Answer:

Step-by-step explanation:

The parabola that forms the shape of the satellite dish has its axis of symmetry along the vertical direction, and the vertex at the bottom center of the dish. Let's assume that the vertex of the parabola is at the origin (0,0) of a coordinate system, and the opening of the dish is along the x-axis. Then the equation of the parabola is:

y = a x^2

where "a" is a constant that determines the shape of the parabola. We can find the value of "a" using the given dimensions of the dish.

At the opening of the dish, which has a diameter of 72 feet, the y-coordinate is zero. Therefore, we have:

0 = a (36)^2

Solving for "a", we get:

a = 0

This means that the equation of the parabola is simply y = 0, which is a horizontal line passing through the origin. Clearly, this is not the correct equation for the parabola.

To find the correct equation, we need another point on the parabola. We are given that the depth of the dish at its center, which corresponds to the focus of the parabola, is 9 feet. Using the definition of a parabola, we know that the distance from any point on the parabola to the focus is equal to the distance from that point to the directrix. Since the axis of symmetry is vertical, the directrix is a horizontal line located 9 feet below the vertex.

The equation of the directrix is therefore:

y = -9

We can use this to find another point on the parabola. Consider a point (x,y) on the parabola that is equidistant from the focus (0,9) and the directrix y = -9. The distance from (x,y) to the focus is:

d = sqrt(x^2 + (y-9)^2)

The distance from (x,y) to the directrix is simply y + 9. Therefore, we have:

sqrt(x^2 + (y-9)^2) = y + 9

Squaring both sides and simplifying, we get:

x^2 = 4y(18-y)

This is the equation of the parabola. We can now find the x-coordinate of the receiver, which is located at the focus (0,9). Setting y = 9 in the equation of the parabola, we get:

x^2 = 4(9)(9) = 324

Therefore, the x-coordinate of the receiver is:

x = ±18

Since the dish is 72 feet across at its opening, the receiver should be located at a distance of 36 feet from the center of the dish. Therefore, the receiver should be placed at a height of:

y = 9 + 36 = 45 feet

above the vertex of the parabola.
