Total price paid by Michael for the basket of mangoes is $4.48.

For the calculation of total price, price of sales tax will be added with selling price. Forming the equation -

Total price = 4 + 12%×4

Calculating the percentage of sales tax on Right Hand Side of the equation

Total price = 4 + 12×4/100

Solving the percentage part on Right Hand Side of the equation

Total price = 4 + 0.48

Performing addition on Right Hand Side of the equation

Total price = $4.48

Hence, Michael has to pay $4.48 after addition of sales tax for the basket of mangoes.

The coefficient of determination if the total sum of squares is 23.29 and the sum of squares due to regression is 10.03 is 0.43

How to calculate regression?

The standard formula for simple linear regression is Y = mX + b, where Y is the response (dependent) variable, X is the predictor (independent) variable, m is the estimated slope, and b is the estimated intercept.

Here we need to find the coefficient determination if the total sum of squares (sst) is 23.29 and the sum of squares due to regression (ssr) is 10.03.

Here we know that the value of the following are given,

Sum of square = 23.29

Sum of regression = 10.03

Then the coefficient determination is calculated as,

The coefficient of determination r2 = SSR/SST.

When we apply the value, then we get,

=> 10.03/23.29

=> 0.43

No, it is not appropriate to estimate the probability using an approximately normal model because the population is not normal and the sample size is small.

The details given are,

Sample size = 9

Standard deviation = 8.99

Therefore we conclude that is it not  appropriate to calculate the likelihood of the sample mean being less than 30 seconds using an approximately normal model.

Handball = 7

Step-by-step explanation:

21 pieces = 2:1n

step 1

Add the ratios together

21 = 3n

Step 2

divide both sides by 3

n = 21/3 = 7

When we divide the 464 by 60 we get the following remainder in our answer that is 44.

The Remainder is the name for the value that is left behind after division. If an amount (reward) cannot be divided completely with another number, we are left with only a meaning (divisor). The remaining is the name for this amount. For instance, 10 is not precisely divisible by 3. We can calculate 3 x 3 = 9 because that is the closest value.

6 games are played by Xochitl and 3 rides went on by Xochitl

Two or more expressions with an Equal sign is called as Equation.

Given that the Xochitl is going to a carnival that has games and rides

The cost of each game is $2.50 and cost of each ride is  $5.

Xochitl spent $30 altogether on 9 games

Let x represents the number of games and y represents the number of rides.

By the given information we form two equations.

x+y=9...(1)

2.5x+5y=30...(2)

From equation (1)

x=9-y

Now plug in x value in (2)

2.5(9-y)+5y=30

22.5-2.5y=30

Subtract 22.5 on both sides

-2.5y=30-22.5

-2.5y=7.5

Divide both sides by 2.5

y=3

x+y=9

x+3=9

x=6

Hence, the number of games Xochitl played is 6 and the number of rides Xochitl went on is 3.

What is meant by null hypothesis?

The null hypothesis, often known as H₀, is the assertion that there is no difference between two sets of data or variables under analysis, or that there is no relationship between them. Because there is no underlying causative relationship, the null hypothesis holds that any experimentally detected difference is merely the result of chance; therefore, the name "null."

We can create a z-test hypothesis by assuming that the amount of rain produced by thunderheads follows a distribution that is nearly normal:

300 acre feet is the null hypothesis for the average quantity of rain that thunderheads produce on their own without fertilizing the clouds.

Alternative Hypothesis: The amount of rain that thunderheads often produce by seeding the clouds is greater than 300 acre feet.

Answer:

  Zach is correct

Step-by-step explanation:

You want to know if reflection across the two axes and translation right will achieve the same effect if the transformations are done in any order.

Translation right adds a value to the x-coordinate.

Reflection over the y-axis changes the sign of the x-coordinate.

If the order of these two transformations is changed, the result will change.

Example

Consider point (0,0) and the translation right 1 unit.

  Reflection, then translation: (0, 0) ⇒ (0, 0) ⇒ (1, 0)

The first and the second terms of the recursive sequence are given as follows:

a) u(1) = -25.

b) u(2) = -15623.

The definition of the recursive sequence is presented as follows:

u(n + 1) = u(n)³ + 2.

The initial term is needed to solve the sequence, hence it is given as follows:

u(0) = -3.

Thus the term with index 1 is given as follows:

u(1) = u(0)³ + 2.

u(1) = -3³ + 2

u(1) = -27 + 2

u(1) = -25.

Considering the term with index 1, the term with index 2 is obtained as follows:

u(2) = u(1)³ + 2

u(2) = (-25)³ + 2

u(2) = -15623.

And then the same rule is obtained if needed to obtain the 3th, 4th terms, and so on, considering the previous term and the definition.
