[tex]5.51134751094269\times10^8[/tex] transistors could fit on a microchip [tex]19[/tex] years later.

Moore's law predicts that the number of transistors that can be fit on a microchip will increase 40% every year.

So the expected increment every year [tex]40\%[/tex].

Microchips from a given year could hold about [tex]922,200[/tex] transistors.

We have to find ow many transistors could fit on a microchip [tex]19[/tex] years later.

From the question total years are [tex]19[/tex].

Since the number of transistors is increased every year so number of transistors of previous year added. So we can see that  the number of transistors that can be fit on a microchip is increased compound. We can find the total number of transistors by multiplying number of transistors with the rate assembled by one. So we can use the formula

So the number of transistors could fit on a microchip 19 years later.

Number of transistor = Microchips from a given year could hold about transistors(1 + increment rate)^total years

Number of transistor [tex]=922,200(1+\frac{40}{100})^{19}[/tex]

Number of transistor [tex]=922,200(1+\frac{2}{5})^{19}[/tex]

Number of transistor [tex]=922,200(\frac{5+2}{5})^{19}[/tex]

Number of transistor [tex]=922,200(\frac{7}{5})^{19}[/tex]

After evaluating the expression using the calculator we get

Number of transistor [tex]=551134751.094269[/tex]

Number of transistor [tex]=5.51134751094269\times10^8[/tex]

Hence, [tex]5.51134751094269\times10^8[/tex] transistors could fit on a microchip [tex]19[/tex] years later.

Answer:

x = 9

Step-by-step explanation:

3(x - 5) = 12 ← distribute the parenthesis on the left by 3

3x - 15 = 12 ( add 15 to both sides )

3x = 27 ( divide both sides by 3 )

Solution of the given algebraic expression (f-g)(x) is equal to 4x³+6x²-7x-1

Algebraic equations are defined as mathematical statements in which two algebraic expressions are set equal to each other. An algebraic expression usually consists of  variables,  coefficients and  constants. Algebraic equations can be of many types, such as monomial algebraic equations, binomial algebraic equations, quadratic algebraic equations, polynomial equations.  

Given in the question that the value of f(x) is equal to 4x³+6x²-3x-4

and the value of g(x) is equal to 4x-3.

The value of x is 25. It states that when two parallel lines are cut by a transversal, the resulting alternate interior angles or alternate exterior angles are congruent.

Parallel lines are coplanar straight lines that do not intersect at any point in geometry. Parallel planes are planes that never meet in the same three-dimensional space. Parallel curves are those that do not touch or intersect and maintain a constant minimum distance.

Parallels, paralleling, and paralleled are all word forms. a countable noun A parallel is something that is similar to something else but exists or occurs in a different place or at a different time.

Parallel lines are lines that are always the same distance apart in a plane. Parallel lines never cross. Perpendicular lines are those that intersect at a right angle (90 degrees).

Two different interior angles.

The measure of the angle y is 49 degrees if AB=AD and BC=DC; the answer is 49 degrees.

It is defined as a four-sided polygon in geometry having four edges and four corners. The kite is quadrilateral, having two pairs of congruent sides and it has one pair of opposite congruent angles.

The kite is given in the picture.

AB = AD

BC = DC

∠DBC + ∠CBD +  ∠C = 180  

From the property of kite: ∠DBC = ∠CBD

y + y + 82 = 180

y = 98/2

y = 49 degrees

Thus, the measure of the angle y is 49 degrees if AB=AD and BC=DC; the answer is 49 degrees.

We have a rectangular slab.

The volume of concrete is equal to the volume of this rectangular prism.

The volume of this prism is equal to the product of its length, width and thickness.

Then, we can write:

We convert the thickness from inches to feet by multiplying it by a unit ratio 1 ft / 12 inches, which has a value of 1, as 1 ft = 12 inches, but let us change the units from inches to feet.

When we have all the measures in feet we can have the volume in cubic feet.

The 95% confidence interval for the mean score of all such subjects. will be ( 67. 7 , 84.7) using mean.

What is mean?

Mathematicians, particularly statisticians, use a variety of means. Every mean serves to condense a certain set of facts, frequently to help grasp the general significance of a particular data set.

sample mean = x' = 76.2

sample S = 21.4

sample size n = 27

Confidence level = a = 0.95
α=1-a=0.05
95% confidence interval for the mean score of all such subjects is
(x'-E , x'+E)
E = [tex]\frac{tc*s}{\sqrt{n}}[/tex]
E = [tex]\frac{2.056*21.4}{\sqrt{27}}[/tex]} = 8.466

95% confidence interval for the mean score of all such subjects is
(x'-E , x'+E)
=(76.2-8.466 , 76.2+8.466)

The covariance value between two variables says, days to 230 lbs and backfat thickness, is 0.48..

The covariance value between any two variables is used to determine whether the variables are changing in the same direction. It relates the two variables if they are from different data sets.

Let X and Y be two data sets with different values. Then the covariance between X and Y is given by

Cov ( X,Y) = ∑ ( X ᵢ– u) ( Yⱼ-v ) /n

Where are Xᵢ's elements in the X data set

Yⱼ→ elements of the Y set

μ → mean of X data set

ν→ mean of Y set

n→ total number of observations

As we have given two sets of data, let days to 230 lbs and backfat thickness be sets X and Y, respectively.

Now, we shall calculate the mean value for X and Y sets.

Mean of X set = (164+158+180 + +160+198+172+186+178+178+186)/10= 176

The mean of Y set =

 (1.0+ 1.1+ 1.2+ 1.4+1.2+1.3++1.1+1.3+1.4+1.0)/10 = 1.2

Xᵢ– μ - 12 -18 4 -16 22 -4 10 2 2 10

Yⱼ– ν -.2 - .1 0 .2 0 .1 -.1 .1 .2 -.2

(Xᵢ - μ)(Yⱼ- ν) 2.4 1.8 0 - 3.2. 0 0.4 1 4.4 -2

∑ (Xᵢ - μ ) ( Yⱼ - ν) = 4.8

put all the values of variables in above formula we get,. Cov( X, Y) = 4.8 / 10 = 0.48 ..

So, the Covariance between the days of 230lb and backfat thickness is 0.48 ..

not a function

for the function

f(x) = (x -g)(x - h)

To get the x-intercept, we can equate the function to zero

f(x) = (x -g)(x - h) = 0

so (x - g) = 0

which gives x = g

And (x - h) = 0

which gives x = h

Since we have been told that g and h are positive, then it follows that both intercepts are positive

Leah can run 320 yards in 2 minutes at the same rate as she can run 720 yards in 4.5 minutes. The correct option is B. 320.

To find out how many yards Leah can run in 2 minutes at the same rate, we can use the concept of proportionality.

Let's set up a proportion based on the information given:

720 yards / 4.5 minutes = x yards / 2 minutes

To find the value of x, we can cross-multiply:

4.5 minutes × x yards = 720 yards × 2 minutes

Now, divide both sides by 4.5 to solve for x:

x yards = (720 yards × 2 minutes) / 4.5 minutes

x yards = 320 yards

So, Leah can run 320 yards in 2 minutes at the same rate.

The correct answer is B. 320.
