Answer:

44 cards

Step-by-step explanation:

In a standard deck of 52 cards, there are 4 suits each of which has 13 cards.  Since we are finding the minimum value to be fully guaranteed of drawing five spades we can assume the scenario as follows:

If the first 39 cards picked are the complete full suits of hearts, diamonds, and clubs, then we know that the next 13 are spades. Since we have to find at least five spades we add 5 cards to the 39 to get our answer of 44 cards to be absolutely guaranteed.

$85.09

Step-by-step explanation:

Answer:

\(x = \frac{4y^{2} + 1}{ {y}^{2} - 1} \)

Step-by-step explanation:

Please see the attached pictures for the full solution.

Cost - 500

Marked Up - 250

Margin - 71.4286

MxCxMA= $1,750

This may seem confusing, but its $1,750 for the new price, and the equation is:

M= Marked

C= Cost

MA= Margin

The new price of the television is $1750.

To determine the quantity or percentage of something in terms of 100, use the percentage formula. Per cent simply means one in a hundred. Using the percentage formula, a number between 0 and 1 can be expressed. A number that is expressed as a fraction of 100 is what it is. It is mostly used to compare and determine ratios and is represented by the symbol %.

Given:

A television that costs $500 is marked up 250%.

So, the new price is

= 500 + 250% of 500

= 500 + 250/100 x 500

= 500 + 1250

= $1750

Hence, the new price of the television is $1750.

The value of the length of side UX for the right triangle formed by sides tangent to the circle is equal to 3.4 using the Pythagoras rule.

The Pythagoras rule states that in a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides. 

The side XV is perpendicular to the side UV tangent to the circle, which makes the triangle a right triangle.

so by evaluation we derive the value for the hypotenuse UX as follows;

UX = √(3² + 1.6²)

UX = √(9 + 2.56)

UX = √11.56

UX = 3.4

Therefore, the length of side UX for the right triangle is equal to 3.4 using the Pythagoras rule.

The counterexample that makes the conclusion false is:

-5 - 8 = -13 and the conclusion is difference of two positive numbers is always positive.

What are positive and negative numbers ?

Positive and negative numbers are numerical values that represent quantities that are greater than or less than zero, respectively.

Positive numbers are numbers that are greater than zero. Examples of positive numbers include 1, 2, 3, 4, 5, 100, and 1000.

Negative numbers are numbers that are less than zero. Examples of negative numbers include -1, -2, -3, -4, -5, -100, and -1000.

Zero is neither positive nor negative, but it is used as a reference point to distinguish between positive and negative numbers. Positive numbers are located to the right of zero on the number line, while negative numbers are located to the left of zero.

According to the question:
The counterexample that makes the conclusion false is:

-5 - 8 = -13

In this case, the two numbers are positive (5 and 8), but their difference is negative (-13), which contradicts the conclusion that the difference of two positive numbers is always positive.

The model assumption are satisfied in histogram, residuals vs order of collection and residuals vs fitted values.

HIstogram

We can see from the histogram that the residuals are normally distributed, so the assumption that the errors are normally distributed is met.

residuals vs. the fitted values

We find a circular pattern where the errors are concentrated based on the residuals vs. the fitted values. indicating a breach of the assumption of equal variance (homoscedasticity). There is another nonlinear pattern that should be investigated.

Residuals vs. Order of collection

: Because the residuals are randomly distributed, the assumption of equal variance of the residuals is not violated.

Residuals vs. gestational length

A The gear concentration of the residuals in the shape of an oval indicate additional signals from the data that have not been modelled. As a result, the assumption of equal variance of the residuals is violated, and it may also indicate a nonlinear relationship between the dependent and independent variables. This problem can be solved by taking the log of the independent variable and normalising the data.

Parity vs. residuals

Because this is a binary variable, the plot provides no clear indication.

Residuals vs. mother's height

There is a clear oval pattern visible, indicating that the variable is violated.

Residuals vs. mother's weight

There is a clear oval pattern visible, indicating that the variable is violated.

Smoking vs. Residuals

Because this is a binary variable, the plot provides no clear indication.

Overall, this is the next step. We must examine the variables for multicollinearity. Because the residuals histogram is normally distributed, but the residuals vs fitted values has a violation.

We must determine whether the independent variables are correlated with one another. If they are correlated, we must discard the one that is least correlated with the target variable.

Marissa's shape is classified as a scalene and obtuse triangle, considering it's concepts presented in this problem.

The triangle has three sides of unequal length, as the opposite angle measures are different, hence it is classified as an scalene triangle.

(it would be equilateral if all had the same length, and isosceles if two sides have the same length).

The triangle has one angle larger than 90º, hence it is classified as an obtuse triangle.

(acute with no angles of 90º or greater, right with one angle of exactly 90º).

Converting 1. 50μm²  to square meters gives 1. 5 × 10 ^-11

Conversion of units is defined as the conversion of different units of measurement for the same quantity, mostly through multiplicative conversion factors.

From the information given, we are to convert micrometers to square meters

Note that:

1 micrometer ( μm²) = 10^-12m²

Given 1. 50μm² =  xm²

cross multiply

x = 1. 50 × 10^-12

x = 1. 50 × 10^-12

x = 1. 50 × 10^-12

x = 1. 5 × 10 ^-11 square meters

Thus, converting 1. 50μm²  to square meters gives 1. 5 × 10 ^-11

The chance that the player's average over the next 100 times at bat will be .310 or better is .9267

To determine the probability that the player's average over the next 100 times at bat will be .310 or better, we need to consider the probability of getting at least 31 hits in 100 at-bats when the probability of getting a hit in each at-bat is .300.

The probability of getting at least 31 hits in 100 at-bats when the probability of getting a hit in each at-bat is .300 can be calculated as follows:

P(31 hits or more in 100 at-bats) = 1 - P(30 hits or fewer in 100 at-bats)

Using the normal approximation, we can calculate the probability of getting at least 31 hits in 100 at-bats when the probability of getting a hit in each at-bat is .300 as follows:

P(31 hits or more in 100 at-bats) = 1 - P(30 hits or fewer in 100 at-bats)

= 1 - P(z <= (30 - 100(.300)) / √(100(.300)(1 - .300)))

= 1 - P(z <= -1.44)

= 1 - .0733

= .9267

Therefore, the probability that the player's average over the next 100 times at bat will be .310 or better is approximately .9267.
