Suppose that you are playing blackjack against a dealer. in a freshly shuffled deck, what is the probability that neither you nor the dealer is dealt a blackjack?

Equation have infinity solution

Here the equation is 2q-3q =-q.

After solving this we have

                    -q = -q

As Left-hand side is equal to the right-hand side.

Therefore whatever the value we will put for the q, the left and right hand side remains the same.

Therefore this equation has an infinity solution.

The length of the side EF will be 18 inches as the sides opposite to the equal angles are also equal.

We are given a triangle EFG.

In this triangle, we can see that:

∠ E = ∠ F = 23°

Now, we know that the sides opposite to the equal angles are also equal.

So, the side opposite to angle E is GF

And the side opposite to angle F is EF.

This means that EF will be equal to GF.

EF = GF

Now, we are also given that GF = 18 inches.

So, EF will also be:

EF = 18 inches.

Therefore, we get that, the length of the side EF will be 18 inches as the sides opposite to the equal angles are also equal.

Numbers of cubes are  224

We have been given that

side length of cubes is = 1 /4 cm

dimension of prism are

2 cm

7/4 cm

1 cm

Each cube with side lengths of 1/4 have a volume of (1/4)3 . To find how many cubes are needed to fill the prism.

Prism: A glass or other transparent object in prism form, especially one that is triangular with refracting surfaces at an acute angle with each other and that separates white light into a spectrum of colors.

To compute the prism volume in the given dimensions (cm³) and the cube volume in the same dimensions, then find the number of cube volumes in the prism volume.

Prism volume = l×w×h

Cube volume = (side)³

than Prism volume =(2×7/4×1)cm

                               = (3.5)cm

and cube volume = (1/4)³cm

                            = (1/64)cm

Then the number of cubes that will fit in the prism is ...

(Prism volume)/(cube volume)

(3.5)/(1/64)cm= 224 cubes

The differences between the trapezoidal rule and simpson's rule is -

The trapezoidal rule and Simpson's method, the latter a set of formulas of varying complexity, are both Newton-Cotes formulas, that are used to examine and model complex curves.

The trapezoidal rule is just an integration rule that divides a curve into small trapezoids to calculate the area under it. A area under the curve is calculated by adding the areas of all the small trapezoids.

Follow the steps below to use the trapezoidal rule to determine the area under given curve, y = f. (x).

Simpson's rule is used to approximate the area beneath the graph of the function f to determine the value of the a definite integral (such that, of the form  b∫ₐ f(x) dx.

Simpson's 1/3 rule provides a more precise approximation. Here are the steps for using Simpson's rule to approximate the integral ba f(x) dx.

Thus, sometimes we cannot solve an integral using any integration technique, and other times we don't have a particular function to integrate. Simpson's rule aids in approximating the significance of the definite integral in such cases.

Answer:

f(5) = 104

Step-by-step explanation:

To find the value of f(5), we have to plug in 5 into our equation f(x) = 20x + 4.

f(5) = 20(5) + 4

Following our order of operations, we multiply first, then add to get our answer.  

f(5) = 20(5) + 4

f(5) = 100 + 4

The standard deviation of the sample  = 28.

An indicator of how much a set of values vary or are dispersed is the standard deviation. When the standard deviation is low, the values tend to fall within a narrow range of the set's mean, while when it is high, the values tend to deviate from that mean more.

The standard deviation is a tool for calculating market volatility or the variation in asset prices from their mean. A high standard deviation indicates that prices are moving erratically and that an investment will indeed be risky. Low standard deviation indicates stable prices and low risk for investments.

A specimen of 196 observations has a variance of 784. determine the sample's standard deviation.

The principle can makes 4 groups with 7 girls and 8 boys.

The biggest number that divides each of the two or more numbers is known as the HCF, or highest common factor. The Greatest Common Measure (GCM) and Greatest Common Divisor are further names for HCF (GCD). The least common multiple, or LCM, is used to determine the smallest common multiple of any two or more numbers. LCM and HCM are two separate approaches.

According to the given statement ;

We are given that 28 girls and 32 boys volunteer to plant at a school.

The principle divided the girls and boys into identical groups that have girls and boys in each group.

We have to find that how much the principle can make greatest number of groups.

We will find HCF of 28 and 32

28= 2X2X7

32= 2X2X2X2X2

Highest common factor of 28 and 32 =2X2=4

The probability that three of the children have sickle cell anemia and three of the children are healthy 13.2%.

Sickle cell anemia is an autosomal recessive condition, the trait is only visible in the homozygous state.

The parents are heterozygous( Aa × Aa), and the progeny (AA, Aa, Aa, and aa) have a normal probability of 3/4 and an affected probability of 1/4.

The binomial theorem can be used to calculate the probability of a normal and affected child:

Probability =  n! / x! ( n! - x!) × pˣqⁿ⁻ˣ.

Here, n is the total children 6,

Let 'x' be the normal child

Then, n! - x! is the affected child.

Let 'p' is the normal child probability (= 3/4) and

Then, 'q' is affected child probability (= 1/4).

Substituting the values in the formula;

probability = (6!/3!×3!)×(3/4)³×(1/4)³

on solving

probability = 0.1318

probability = 13.18%

probability = 13.2% (approximately)

Therefore,  the binomial theorem to determine the probability that three of the children have sickle cell anemia and three of the children are healthy is 13.2%.

A straight line is an infinite-length line that does not have any curves on it. A straight line can be formed between two points also but both ends extend to infinity. A straight line is a figure formed when two points A (x1, y1) and B (x2, y2) are connected with the shortest distance between them, and the line ends are extended to infinity.

In the image shown below, a straight line between two points A and B is shown. A straight line AB is represented by: Vector AB

The lines are drawn in a slanting position or form some angle other than 0o, 90o, 180o, 270o, 360o with horizontal or vertical lines are called oblique or slanting lines.
