HELP PLEASE! The perimeter is 22. How much bigger is the longest side than the shortest side?
I asked this question two hours ago, and since then, I haven't recived any help. I don't mean to sound demanding and I understand that there are millions of users here, but it seems it's been a while since someone's answered this, and I can't figure it out.

Answer:

Step-by-step explanation

Left at 6:15 am

How many hours until 2:15pm? 8 hours

How many minutes from 2:15 until 2:30? 15

So it took 8 hours and 15 minutes

The probability that the weight of a randomly selected steer is between 1379 and 1590lbs is P(1.39 < z < 1.80) = P(z < 1.80) - P(z < 1.39)

Let X the random variable that represent the weights of a population, and for this case we know the distribution for X is given by:

X~N (1379,1590)

Where we know u = 1200 and a = \(\sqrt{90000}\) = 300

we need probability of

P (1379 < X < 1590)

now we can solve this using z = x-u/a

by using the above formula we get:

1590-1200/300 = P(1.39 < z < 1.8)

And we can find this probability using the normal standard table with this difference:

P(1.39 < z < 1.80) =

P(z < 1.80) - P(z < 1.39)

Answer:

x=-5

Step-by-step explanation:

First set the values equal to each other;

5x-10=3x-20

Add 10 to both sides;

5x-10+10=3x-20+10

Simplify;

5x=3x-10

Subtract 3x from both sides;

5x-3x=3x-10-3x

Simplify;

2x=-10

Divide both sides by 2;

2x/2=-10/2

Simplify 2x/2;

2/2=1

Answer:

15^2 + 16^2= x^2

Step-by-step explanation:

I took the usa test prep test and this is how you calculate it

Answer:

x = 5\(\sqrt{7}\)

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² + 9² = 16²

x² + 81 = 256 ( subtract 81 from both sides )

x² = 175 ( take the square root of both sides )

x = \(\sqrt{175}\) = 5\(\sqrt{7}\) ≈ 13.23 units ( to 2 dec. places )

Answer:

x = 5√7

Step-by-step explanation:

By pythagoras theorem,

(hypotenuse)² = (altitude)² + (base)²

(hyp)² - (base)² = (alt)²

(16)² - (9)² = x²

256 - 81 = x²

x² = 175

x = √175

x = 5√7

The type of sample that a store prints a request on each receipt asking customers to fill out a satisfaction survey online if they are willing is a voluntary response sample.

In the statistics world, a voluntary response sample is a research sample that relies on individual self-selection. This is in opposition to random sampling, in which the samples are gathered in a way that ensures everyone in a particular population has an equal chance of being chosen. This method of self-selection is also known as self-selection bias or sampling bias.Voluntary response samples are subject to a variety of flaws. The responses may not be representative of the population as a whole, and they may be skewed by numerous factors, such as which individuals are most likely to volunteer, how these volunteers differ from the population as a whole, and how the survey questions are phrased.The results of a voluntary response survey may be useful in generating hypotheses or gaining a general sense of how individuals feel about a particular subject. However, they are not reliable enough to draw any conclusions or to be taken seriously in the scientific sense.

The products obtained from the reactions of (E)- and (Z)-hex-3-ene with D2 in the presence of a platinum catalyst are related as enantiomers.

Hence, the correct option is E.

Enantiomers are stereoisomers that are non-superimposable mirror images of each other. In this case, the (E)- and (Z)-isomers have different spatial arrangements around the C=C double bond. When they react with D2 in the presence of a platinum catalyst, the deuterium atoms add to the double bond, resulting in two new chiral centers.

Since the two isomers have different spatial arrangements around the double bond, the addition of deuterium atoms will produce enantiomeric products. Therefore, the products obtained from the reactions of (E)- and (Z)-hex-3-ene with D2 are related as enantiomers.

Hence, the correct option is E.

Step-by-step explanation:

Option B is correct, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.

A parabola is a U-shaped plane curve where any point is at an equal distance from a fixed point and from a fixed straight line which is known as the directrix.

We can start by using the vertex form of the equation of a parabola, which is given by:

y = a(x - h)² + k

where (h, k) is the vertex of the parabola and a determines the shape and direction of the opening of the parabola.

We are given that the vertex is (5, -3),

Substitute h = 5 and k = -3:

y = a(x - 5)² - 3

We also know that the parabola passes through the point (6, 1), so we can substitute x = 6 and y = 1:

1 = a(6 - 5)² - 3

1 = a - 3

a = 4

Substituting a = 4 into the equation

y = 4(x - 5)^2 - 3

Hence, the equation of the parabola in vertex form is y = 4(x - 5)² - 3.

Hu and colleagues (2001) addressed concerns about the lack of random assignment to treatment conditions by using a quasi-experimental design.

In their study, Hu and colleagues (2001) used a quasi-experimental design to examine how organizational citizenship behaviors (OCBs) of bank tellers affect customer service. A quasi-experimental design is a type of research design that lacks the random assignment of participants to treatment conditions, which is a key characteristic of true experimental designs.

To address the concerns about the lack of random assignment in their study, Hu and colleagues (2001) used statistical techniques to control for potential confounding variables and to increase the internal validity of their findings.

Step-by-step explanation:

After 2.94 Hr. or approximately 3 Hr. both cars will be 250 miles apart.

We have,

The value of the speed of the car moving in the north direction =35 mph

The value of the speed of the car moving in the south direction=50 mph

From above, we can conclude that both are going in the opposite direction

So, the value of the net speed/ relative speed of both the car will be =35+50=85 mph

As we know,

The value of distance can be determined by using the relationship:

Distance = speed * time

So, for determining the value of time, we will put the value of total distance covered and the value of relative speed in the above expression.

Thus, we will get it as:

250=85*t

So, the value of the time taken = t=250/85=2.94 hours approx 3 hours

Answer:42

Step-by-step explanation:

The correct option regarding the amount of coins is given as follows:

c 4 nickels, 10 dimes, 4 quarters

The amounts are obtained by a system of equations, for which the variables are given as follows:

Amy has 18 coins consisting of nickels, dimes, and quarters, hence:

x + y + z = 18.

She has the same amount of nickels as quarters, hence:

x = z.

Thus:

2x + y = 18

y = 18 - 2x.

She has a total of $2.20 worth of coins, hence:

0.05x + 0.1y + 0.25z = 2.2

0.3x + 0.1y = 2.2

Since y = 18 - 2x, the value of x is obtained as follows:

0.3x + 0.1(18 - 2x) = 2.2

0.1x = 0.4

x = 0.4/0.1

x = 4.

We have two right-angled triangles that share a common side, with side lengths 6 and 10. Let's label the sides of the triangles as follows:

Triangle 1:

Side adjacent to the right angle: 6 (let's call it 'a')

Side opposite to the right angle: x (let's call it 'b')

Triangle 2:

Side adjacent to the right angle: x (let's call it 'c')

Side opposite to the right angle: 10 (let's call it 'd')

Using the Pythagorean theorem, we can write the following equations for each triangle:

Triangle 1:\(a^2 + b^2 = 6^2\)

Triangle 2: \(c^2 + d^2 = 10^2\)

Since the triangles share a common side, we know that b = c. Therefore, we can rewrite the equations as:

\(a^2 + b^2 = 6^2\\b^2 + d^2 = 10^2\)

Substituting b = c, we get:

\(a^2 + c^2 = 6^2\\c^2 + d^2 = 10^2\)

Now, let's add these two equations together:

\(a^2 + c^2 + c^2 + d^2 = 6^2 + 10^2\\a^2 + 2c^2 + d^2 = 36 + 100\\a^2 + 2c^2 + d^2 = 136\)

Since a^2 + 2c^2 + d^2 is equal to 136, we can conclude that x (b or c) is between 11 and 12
