Quintin divided 5/20÷5/11 what answer would make a quintin correct

Answer:

x = 2.4

Step-by-step explanation:

10x = 24

x = 24 ÷ 10

x = 2.4

Step-by-step explanation:

→ -4 = 20 - 10x

→ -20 - 4 = 10x

→ -24 = 10x

→ x = -24/10

→ x = -2.4

therefore, value of x is -2.4

When a study's findings are highly valid, it means that they accurately reflect the genuine features, traits, and variations in the physical or social reality. The measure of frequency of drinking and driving is: reliable but not valid.

This option contends that although the survey's measure was not valid, it was dependable. This happens when research is constructed in a consistent but ineffective manner. In this instance, a sample of young people from a small town was taken into account; however, despite its consistency and reliability, it does not accurately reflect the findings of data from police records.

How well a method measures what it is supposed to measure is known as its validity. When a study's findings exists highly valid, it indicates that they accurately reflect the genuine features, traits, and variations in the physical or social reality. High dependability exists one sign of a valid measurement.

(A) The equation for the population p in terms of time t in minutes is:

                  \(P = 250 * 3^{t/16}\)

(B) The population after one hour is 267.5

According to the Question,

Given that,

(B) Tyrell is working in a lab testing bacteria populations. After starting out with a population of 250 bacteria, he observes the change in population and notices that the population triples every 15 minutes.

Therefore, the equation for the population P in terms of time t in minutes is

   \(P = 250 * 3^{t/16}\)

(B) The population after one hour.

   \(P = 250 * 3^{t/16}\\P = 250* 3^{1/16} \\P = 250*3^{0.0625}\)    P

Answer:

y = -4/5x + 2 & y = -2/7x - 4/7

Step-by-step explanation:

(4x) - 5y = -10                                             (2x) - 7y = 4

Move 4x on the same side as -10            Move 2x on the same side as 4

-5y = 4x -10                                                -7y = 2x + 4

Divide -5 to both sides                              Divide -7 by both sides

That should isolate the y for both equations.

4x/-5 = -4/5x....-10/-5 = 2                            2x/-7 = -2/7x....4/-7 = -4/7

y = -4/5x + 2                                                y = -2/7x - 4/7

m = 3 and n = -1

======================================================

Explanation:

Let's first factor out the GCF

m^3n^2 + m^2n^5

m^2n^2(m + n^3)

The term m^2n^2 is always nonnegative because squaring a negative leads to a positive (eg: (-10)^2 = 100).

So the entire expression is positive when m+n^3 is also positive. In other words when m+n^3 > 0.

If we tried something like m = -2 and n = -2, then,

m + n^3 > 0

-2 + (-2)^3 > 0

-2 + (-8) > 0

-10 > 0

Which is false. So we rule out choice B. You should find that choices C and D lead to similar conclusions. Only choice A works

m + n^3 > 0

3 + (-1)^3 > 0

3 + (-1) > 0

2 > 0

we get a true result here. Note that this happens because the value of m is larger than the absolute value of the result of n^3, which helps keep m+n^3 in positive territory.

The time taken to triple the principal investemet for an interest compounded semi-annually is approximately 267 months.

The formula accrued amount in a compounded interest is expressed as;

\(A = P( 1 + \frac{r}{n})^{(nt)}\)

Where A is accrued amount, P is principal, r is interest rate and t is time.

Given that:

P = principal amount (initial investment) = $2000

A = final amount (triple the initial investment) = 3 × $2000 = $6000

r = interest rate per period = 5%

n = number of compounding periods per year n = 2

t = time in years = ?

First, convert R as a percent to r as a decimal

r = R/100

r = 5/100

r = 0.05

Plug the given values into the above formula and solve for time taken t.

\(A = P( 1 + \frac{r}{n})^{(nt)}\\\\t = \frac{In(\frac{A}{P}) }{n(In( 1 + \frac{r}{n}) } \\\\t = \frac{In(\frac{6000}{2000}) }{2(In( 1 + \frac{0.05}{2}) } \\\\t = 22.246\ years \\\\t = 267\ months\)

Therefore, the time taken is approximately 267 months.

In the basis step of the mathematical induction proof for P(n), we show that the equation is true for n = 1. The equation of the inductive hypothesis (IH) is P(k), where k is an arbitrary natural number. In the inductive step, we need to show that if P(k) is true, then P(k+1) is also true.

In the basis step, we substitute n = 1 into the equation 11⋅2+12⋅3+⋅⋅⋅+1n⋅(n+1)=nn+1. This gives us the equation 1⋅2 = 1+1, which is true.

The inductive hypothesis (IH) is denoted as P(k), where k is an arbitrary natural number. We assume that P(k) is true, meaning that 11⋅2+12⋅3+⋅⋅⋅+1k⋅(k+1)=kk+1 holds.

In the inductive step, we need to show that if P(k) is true, then P(k+1) is also true. This involves substituting n = k+1 into the equation 11⋅2+12⋅3+⋅⋅⋅+1n⋅(n+1)=nn+1 and demonstrating that the equation holds for this value. The specific equation we need to show in the inductive step is 11⋅2+12⋅3+⋅⋅⋅+1(k+1)⋅((k+1)+1)=(k+1)(k+1+1).

In the basis step, we need to show that the equation P(1) is true. The equation of the inductive hypothesis (IH) is P(k), where k is any natural number greater than or equal to 1. In the inductive step, we need to show that if P(k) is true, then P(k+1) is also true.

To prove the equation P(n): 11⋅2 + 12⋅3 + ... + 1n⋅(n+1) = n(n+1) using mathematical induction, we follow the two-step process.

1. Basis Step:

We start by showing that the equation is true for the base case, which is n = 1:

P(1): 11⋅2 = 1(1+1)

Simplifying, we get: 2 = 2, which is true.

2. Inductive Step:

Assuming that the equation is true for some arbitrary value k, the inductive hypothesis (IH) is:

P(k): 11⋅2 + 12⋅3 + ... + 1k⋅(k+1) = k(k+1)

In the inductive step, we need to show that if P(k) is true, then P(k+1) is also true:

P(k+1): 11⋅2 + 12⋅3 + ... + 1k⋅(k+1) + 1(k+1)⋅((k+1)+1) = (k+1)((k+1)+1)

By adding the (k+1)th term to the sum on the left side and simplifying the right side, we can demonstrate that P(k+1) is true.

The equation, in slope-intercept form, of the line zw is y = x.

It is given that, equation of the line pq is:-

y = -x + 2

Also, line pq is perpendicular to line zw

zw passes through the point z (11,11).

We have to find the equation, in slope-intercept form, of the line zw.

The slope intercept form of a line is:-

y = mx + b

Where,

m represents slope of the line,

(x,y) represents every point on the line

b represents the y-intercept of the line

We know that, when two lines are perpendicular, the product of slopes of the lines is -1.

Let the slope of the line zw be m.

Hence,

m*(-1) = -1

m = 1

As it passes from the point z(11,11).

Hence, we can write,

11 = 1(11) + b

11 = 11 + b

b = 0

Hence, the slope intercept form of the line zw is y = x .

To calculate the amount of money that Maura spends on each scarf the following is carried out.

The amount of money that she spends on the scarf material = $5.50

The percentage selling price of each scarf = 600% of $5.50

That is ;

Step-by-step explanation:

The probability that the first item is not the first to be delivered is 0.5567.

Given that Meredith orders three items from an online retailer, where the first item will arrive with equal likelihood in one of the first through third days of February, the second will arrive with equal likelihood in one of the second through fourth days of February, and the third will arrive with equal likelihood in one of the third through fifth days of February.

The number of possible outcomes when the first item can be delivered is 3, and the number of possible outcomes when the second item can be delivered is 3, and the number of possible outcomes when the third item can be delivered is 3.

So the total number of possible outcomes is 3*3*3=27. Since there can only be one item delivered in a given day, it is not possible for all three items to be delivered on the same day. Hence the cases where all the items arrive on the same day need to be excluded.

There are 3 cases where all the items arrive on the same day. Therefore, the total number of favorable outcomes is 27-3=24.

The cases where the first item is delivered first are the cases where the first item arrives on February 1, February 2, and February 3, and the second and third items arrive on February 2 and February 3. This means that there are 3 favorable outcomes where the first item is delivered first.

Therefore, the probability that the first item is not the first to be delivered is P(First item is not the first to be delivered)=1-P(First item is the first to be delivered) P(First item is the first to be delivered)=3/24=1/8P(First item is not the first to be delivered)=1-1/8=7/8=0.8750

Thus the probability that the first item is not the first to be delivered is 0.8750 or 0.5567 (rounded to 4 decimal places).
