Step-by-step explanation:

There are 38,400 different ways for Xing to construct a banana split at this ice cream shop if he is allowed to choose between zero and three sprinkled toppings.

a) In order to construct a banana split, Xing needs to select 3 flavors of ice cream, 6 sauces, and 3 sprinkled toppings. Therefore, the formula for the number of ways to construct a banana split is (20 flavors)(6 sauces)(10 toppings)^3. When calculated, this number is 28,800. This means that there are 28,800 different ways for Xing to construct a banana split at this ice cream shop.

b) In this scenario, the formula for the number of ways to construct a banana split is (20 flavors)(6 sauces)(10 toppings)^0 + (20 flavors)(6 sauces)(10 toppings)^1 + (20 flavors)(6 sauces)(10 toppings)^2 + (20 flavors)(6 sauces)(10 toppings)^3. When calculated, this number is 38,400. This means that there are 38,400 different ways for Xing to construct a banana split at this ice cream shop, with the option to choose zero, one, two, or three sprinkled toppings.

Therefore, there are 38,400 different ways for Xing to construct a banana split at this ice cream shop if he is allowed to choose between zero and three sprinkled toppings.

the CPI to the nearest tenth in 1950 was 24.06.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

Given, a bottle of dishwashing detergent cost $0.31 in 1950 and In 1970, a bottle of dishwashing detergent cost $0.50

Since CPI, Consumer Price Index measures the overall change in consumer prices based on a representative basket of goods and services over time.

The price of dishwashing detergent increased at the same rate as the CPI from 1950 to 1970.

So,

0.50 / 0.31 = CpI for 1970/ CPI for 1950

Since CPI in 1970 is 38.80

CPI in 1950 = 0.62 * 38.80

CPI in 1950 = 24.056

Therefore,  the CPI to the nearest tenth in 1950 was 24.06.

Option (b) is correct. The sample size was not sufficiently large.

The histogram that is shown at the end of the answer shows the results of the simulation. We can clearly see that there are different variations in the population size. There are various reasons which can cause the simulation not to be normal. The main reason for this if the sample size is not big enough. That is because a theory stated that when the sample size taken by a person or researcher is not large or insufficient for the alpha level as well as the analysis one chooses to do, it will limit the statistical power of the study.

Due to the above, we can say that the sample size is not big enough that's why the simulation of the sampling distribution is not approximately normal. So option (b) is correct.

You can use the fact that both the cars were travelling at the same speed so we can take them equal to some variable.

The speed of the cars was 0.8 miles per hour

How to form may you can represent the unknown amounts by the use of variables. Follow whatever the description is and convert it one by one mathematically. For example if it is asked to increase some item by 4 , then you can add 4 in that item to increase it by 4. If something is for example, doubled, then you can multiply that thing by 2 and so on methods can be used to convert description to mathematical expressions.

How  to find the speed of the cars?

Supposing that both the cars were travelling with the speed

Let the first car travels  miles

then as second car travels 12 miles extra, thus, distance traveled by second car is  miles.

Using the formula for speed, we have:

For first car:

Distance traveled =  miles

Speed =

Time taken =

Thus,

For second car:

Distance traveled =  miles

Speed =

Time taken =

Thus,

So, we got system of 2 linear equations in two variables.

Using the expression for x from first equation and substituting it in second equation, we get

Substituting this value in first equation to get the value of x

Thus,

The speed of the cars was 0.8 miles per hour

The domain of the composite function (f o g)(4) for f(x) = 4x - 3 and g(x) = x³ + 2x is equal to -59.

A function is composite when the co-domain of the first mapping is the domain of the second mapping

We shall evaluate the domain of the function (f - g)(4) as follows:

(f - g) = 4x - 3 - (x³ + 2x)

(f - g) = 4x - 3 - x³ - 2x

(f - g) = 2x - 3 - x³

(f - g)(4) = 2(4) - 3 - (4)³

(f - g)(4) = 8 - 3 - 64

(f - g)(4) = -59

The volume common to the two spheres is V = 2 * (2/3) * pi * r^3 = (4/3) * pi * r^3.

The volume shared by two spheres with radii r and centers separated by r/2 can be calculated by using the volume of a sphere equation and subtracting the volumes of two smaller spheres cut out by the intersection of the larger spheres.

Assume that the two spheres are centered at (r/2,0,0) and (-r/2,0,0). Finding the points where it intersects with a plane perpendicular to the x-axis and passes through the x-axis at x = r/4.

This plane cuts the spheres at two points, and the smaller spheres have the same radius as the distance between these points.

The radius of these spheres can be found using the Pythagorean theorem:

r = sqrt(r^2 - (r/2)^2) = sqrt(3r^2/4)

The volume of each smaller sphere is given by:

V = (4/3) * pi * (r)^3 = (4/3) * pi * (sqrt(3r^2/4))^3 = (2/3) * pi * r^3

Therefore, the volume common to the two spheres is given by:
