A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given, 33% of millennials rely on blogs before making a purchase.

Eight out of 10 millennials never buy anything without reading a review first.

That means,

8 out of 10 is 80%.

In a sample size of 75 millennials:

To find the number of people that never buy anything without reading a review first:

80% of 75

80 x 75 / 100

= 6000/ 100

= 60

To find the number of people that use blogs to make a purchase:

33% of 75

33 x 75 / 100

= 2475/ 100

Step-by-step explanation:

If I make x the scope of mix and y the quarts of water, my equation would be y = .125x

I can find the constant of Proportionally by y/x

Using points (4,.5) and (12,1.5)

(.5/4) = 0.125

(1.5/12) = 0.125

The equation would then be:

y = 0.125x

C see the graph provided from Desmos (a free graphing calculator).  as x Increases by 1, y increases by 0.125

y = 0.125x

y =.0125(20)

y = 2.5

For 20 scoops, I would need 2.5 quarts of water.

You can also see from the graph as 8 scoops, I would need 1 quart of water.

A stock price will rise if demand for stock is greater than supply. So, the correct answer is option (d).

The stock price or share price is the amount of money it costs to buy shares in a company. Stock prices are not fixed and fluctuate based on market conditions. It is likely to go up if the company is viewed as good, and it is likely to go down if the company is not performing as expected. If there are more people who want to buy a demand than sell (supply ) it, the stock price will go up. Conversely, if more people want to sell than buy stocks, there will be more supply than demand and prices will fall. Understanding supply and demand is easy.

Answer:

A. x = -6

Step-by-step explanation:

-1/6x - 5 = 2/3x

add 1/6x to both sides:

-1/6x - 5 + 1/6x = 2/3x + 1/6x

-5 = 2/3x + 1/6x

common denominator on right side:

-5 = 4/6x + 1/6x

combine right side:

-5 = 5/6x

multiply both sides by 6/5:

(-5)(6/5) = (5/6x)(6/5)

-30/5 = x

reduce left side:

-6 = x

x = -6 (option a)

Answer: A) x=-6

Step by step explanation:

[tex]\boldsymbol{\sf{\dfrac{-1}{6}x-5=\dfrac{2}{3}x }}[/tex]

We calculate the multiplication expression.

An ellipse's equation has its origin at its center, its foci on the y-axis, and its major axis at x2/16+y2/144, which is three times longer than its minor axis.

In mathematics, an ellipse is a planar curve with two focal points, where the total of the two distances from any point on the curve to the focal points is a constant.

It generalizes the shape of a circle, a unique variety of ellipse in which the two focus points coincide.

The eccentricity of an ellipse,  , which ranges from 0 (the limiting case of a circle) to 1 (the length of the ellipse), is used to determine how long it is (the limiting case of infinite elongation, no longer an ellipse but a parabola).

The area of an ellipse has a straightforward algebraic solution, while the perimeter (also known as circumference), for which integration is necessary to arrive at a precise answer, only has approximations.

According to our question-

M(X0|Y)   M(0|0)

(X-X0)^2/a^2 +(Y-Y0)^2/b^2=1

x2/a2+x2b2=1

a=4 b=3 .a=12

x2/16+y2/144

Hence, An ellipse's equation has its origin at its center, its foci on the y-axis, and its major axis at x2/16+y2/144, which is three times longer than its minor axis.

The solution to a system of equations is the set of points that satisfy all of the equations at once. On a graph, it will be the set of points where the graphs of the equations intersect.

Here the two lines cross at one point, hence there is one solution.

The point where the lines cross is approximately (3, -0.5). That makes (3, -0.5) a reasonable estimate of the solution of the system.

Answer:

22

Step-by-step explanation:

Let's say the 4 consecutive integers are a, b, c, and d

a=b-2  ==> Consecutive even numbers have a difference of 2: Ex. (4-2=2)

b=c-2

c=d-2

a+b+c+d=100

Solve for a:

a=b-2  ==> add 2 on both sides

a+2=b

a+(a+2)+c+d=100  ==> substitute a+2 for b

a+2=c-2  ==> b=c-2 and a+2=b, so a+2=c-2

a+2+2=c-2+2  ==> add 2 on both sides

a+4=c

a+(a+2)+(a+4)+d=100 ==> substitute a+4 for c

a+4=d-2  ==> c=d-2 and a+4=c, so a+4=d-2

a+4+2=d-2+2  ==> add 2 on both sides

a+6=d

a+(a+2)+(a+4)+(a+6)=100  ==> substitute a+6 for d

a+a+2+a+4+a+6=100  ==> solve for a

a+a+a+a+2+4+6=100

4a+12=100 ==> simplify

4a+12-12=100-12 ==> isolate a

4a=88  ==> simplify

a=88/4

a=22

The solutions of the given system of equations are, (-2, 11) and (-1, 6).

What is system of equations?

A group of equations involving one or more variables is known as a system of equations. The variable mappings that satisfy each component equation, or the points where all of these equations intersect, are the solutions to systems of equations.

Consider, the given system of equations

y = x^2 - 2x + 3            ..(2)

y = -5x + 1                    ..(1)

Plug value of y in equation (1).

⇒ -5x + 1 = x^2 - 2x + 3

x^2 - 2x + 3 + 5x - 1 = 0

x^2 + 3x +2 = 0

x^2 + 2x + x + 2 = 0

x(x + 2) + 1(x + 2) = 0

(x + 2)(x + 1) = 0

(x + 2) = 0,      (x + 1) = 0

       x = -2,             x = -1

Now to find the value of y for each value of x.

Plug x = -2 in equation (2)

y = -5(-2) + 1 = 10 + 1 = 11

Plug x = -1 in equation (2)

y = -5(-1) + 1 = 5 + 1 = 6

The null hypothesis is a statement of a general population parameter that is assumed to be true. It is typically tested using a statistical test, such as an independent t-test or ANOVA. If the null hypothesis is not rejected at the 5% level of significance, it does not necessarily mean that it will also not be rejected at the 1% level. This is because the 1% level of significance is a stricter level of significance, meaning that the sample data must be even more extreme in order to reject the null hypothesis. Thus, the null hypothesis may be rejected or not rejected at the 1% level, depending on how extreme the data are.

If her current wealth is $100 and f 0.25, then she bets $25 and either gains or loses that amount then the probability is 0.139.

It is given that Xj is the amount she has immediately after the j the bet is settled.

In the J+1 the bet, she bets fXj of her welath, which has a probability of win of P and probability  of loss of 1-p.

Thus:

Xj+1 = Xj + fpXj - f(1-p)Xj

the nth term is 2n

Step-by-step explanation:

notice how for each number of tiles, 2, 4, 6, 8, 10, they are all multiples of 2, so like ok 2 is definitely in the term, next check how n can fit. Well, since they are multiples, you multiply n by 2, now check to see if you dont need to add any values by the following method:

first number = 2,  then 2(1) = 2 if n = 1

second = 4, then (2)(2) = 4 if n = 2

its all the same for the rest. Each new diagram or tile structures represents n, so if n =1, then there are 2 tiles, if n = 4 there are 8 tiles and so on, which explains us why the nth term is 2n

The nth term formula for the number of square tiles in the nth figure is aₙ=2n.

An arithmetic sequence is a sequence of numbers where the differences between every two consecutive terms is the same. The general form an arithmetic sequence is aₙ=a+(n-1)d.

To write the equation in exponential form we must follow certain rules:

1. Logarithm product rule -            log b ( x ∙ y) = log b ( x) + log b ( y)

2. Logarithm quotient rule -           log b ( x / y) = log b ( x) - log b ( y)

3. Logarithm power rule -               log b ( x y) = y ∙ log b ( x)

4. Logarithm base switch rule -     log b ( c) = 1 / log c ( b)

1. ㏒z(w) = p

Here all constants are taken to be positive and not equal to 1

z = base of the logarithmic function

z^p = w --------> (1)

This z^p = w is the exponential form of ㏒z(w) = p

2. ㏒(s) = r

Here all constants are taken to be positive and not equal to 1

e = base of the logarithmic function

e^r = s --------> (2)

This e^r = s is the exponential form of ㏒(s) = r

3. 7m = a

Here we have to write the equation in logarithmic form

㏒(7m) = log r

log(7m) - log r = 0

We know quotient rule :-

log b ( x / y) = log b ( x) - log b ( y)  --------(A)

Applying that same principle to our question by using this equation we have:
