Step-by-step explanation:

Let's factor z2−10z+25

z2−10z+25

The middle number is -10 and the last number is 25.

Factoring means we want something like

(z+_)(z+_)

Which numbers go in the blanks?

We need two numbers that...

Add together to get -10

Multiply together to get 25

Can you think of the two numbers?

Try -5 and -5:

-5+-5 = -10

-5*-5 = 25

Fill in the blanks in

(z+_)(z+_)

with -5 and -5 to get...

(z-5)(z-5)

Answer: (Z - 5) (Z - 5)

Answer:

\(y_1 = -2\) and \(y_2 = 4\)

Step-by-step explanation:

\( \sqrt{10y + 24} - 3 = y + 1\)

Move the constant to the right-hand side and change their sign.

\( \sqrt{10y + 24} = y + 1 + 3 \)

combine like terms

\( \sqrt{10y + 24} - 3 = y + 4\)

Square both side to remove square brackets.

10y + 24 - 3 = y²+ 8y + 16

Move the expression to the left-hand side and change its sign.

10y + 24 - y² - 8y - 16 = 0

Combine like terms

10y - 8y + 24 - 16 - y² = 0

2y + 8 - y² = 0

Use commutative property to reorder the terms.

-y² + 2y + 8 = 0

Change the sign of expression.

y² -2y -8 = 0

split -2y

y² + 2y - 4y - 8 = 0

Factor out y from the first pair and -4 from the second equation.

y ( y + 2 ) - 4 ( y + 2 ) = 0

Factor out y+2 from the expression.

( y + 2 ) ( y - 4)

When the products and factors equals 0, at least one factor is 0.

y + 2 = 0

y - 4 = 0

Solve for y

y = -2

y = 4

When we plug the both solution as y we found that both is true solution of this equation.

This equation has two solutions which are -2 and 4.

Answer:

Solution given:

\( \sqrt{10y + 24} - 3 = y + 1\)

keep the constant term in one side

\( \sqrt{10y + 24} =y+1+3\)

solve possible one

\(\sqrt{10y+24}=y+4\)

now

squaring both side

\((\sqrt{10y+24})²=(y+4)²\)

10y+24=y²+8y+16

taking all term on one side

10y+24-y²-8y-16=0

solve like terms

8+2y-y²=0

doing middle term factorisation

8+4y-2y-y²=0

4(2+y)-y(2+y)=0

(2+y)(4-y)=0

either

y=-2

or

y=4

The statement "Because in a randomized controlled trial (RCT), the assignment is random, therefore there is no coverage bias---by definition" g is false because, it is important to consider both randomization and other factors when assessing the potential for bias in an RCT.

Random assignment in an RCT can help to reduce selection bias, but it does not guarantee the absence of coverage bias.

Coverage bias can occur if the participants who are enrolled in the trial do not represent the population to which the results will be generalized.

For example, if the trial only includes participants who are healthier or more compliant than the typical patient, the results may not be applicable to the broader population.

Therefore, it is important to consider both randomization and other factors when assessing the potential for bias in an RCT.

There are 1350 4-digit numbers that have the second digit even and the fourth digit at least twice the second digit.

To form a 4-digit number, we have 10 choices for each digit, except the first digit, which can't be 0. Hence, there are 9 choices for the first digit.

For the second digit, there are 5 even digits (0, 2, 4, 6, 8) to choose from.

For the third digit, there are 10 choices.

For the fourth digit, we can choose any of the even digits we picked for the second digit, or any of the larger odd digits 4, 6, 8.

Hence, the number of 4-digit numbers that meet the given criteria is

9 × 5 × 10 × 3 = 1350.

The actual implications of giving a bone to a subject would depend on the specific context, such as the subject's identity (human or animal), the purpose of giving the bone, and the cultural or medical considerations involved.

Assuming that a randomly selected subject is given a bone, it seems that we need to consider the context and determine the implications or consequences of this action. Without further information, it is difficult to provide a specific explanation or analysis. However, we can discuss some general possibilities and considerations related to giving a bone to a subject.

1. Medical Treatment: Giving a bone could be related to medical treatment or procedures. For example, in orthopedic medicine, bones may be used for grafting or reconstructive surgeries to repair damaged or fractured bones.

2. Nutritional Benefits: Bones, such as beef or chicken bones, can be used to make broths or stocks that are rich in nutrients like collagen, calcium, and other minerals. These bone-based products are often consumed for their potential health benefits.

3. Animal Care: Giving a bone to an animal, particularly dogs, is a common practice. Bones can serve as a form of entertainment or enrichment for pets, satisfying their chewing instincts and providing dental benefits.

4. Symbolic Meaning: In certain cultures or traditions, bones can hold symbolic meanings. They may be used in rituals, ceremonies, or artistic expressions to represent various concepts, such as strength, mortality, or spirituality.It's important to note that the above interpretations are speculative and based on general assumptions. The actual implications of giving a bone to a subject would depend on the specific context, such as the subject's identity (human or animal), the purpose of giving the bone, and the cultural or medical considerations involved.

The patient is recieving nearly 35.5 miligrams of the drugs for  per kilogram per 24 hours.

First, we need to convert the child's weight from pounds to kilograms:

99 lbs / 2.205 = 44.9 kg

Next, we calculate the recommended dose for this weight:

40 mg/kg/24h x 44.9 kg = 1796 mg/24h

Since the recommended dose is divided into four equal doses, each dose should be:

1796 mg/24h ÷ 4 doses = 449 mg/dose

However, the physician ordered 400 mg every 6 hours, which is not the same as 449 mg every 6 hours. To calculate the actual dose per kilogram per 24 hours, we need to convert the ordered dose to the recommended dose:

400 mg/dose x 4 doses = 1600 mg/24h

Then, we divide the actual dose by the child's weight in kilograms:

1600 mg/24h ÷ 44.9 kg = 35.6 mg/kg/24h

Therefore, the patient is receiving 35.6 mg/kg/24h, which is slightly lower than the recommended dose of 40 mg/kg/24h.

A company produces two types of smartphones: Model X and Model Y. The profit from each Model X sold is $150, while the profit from each Model Y sold is $200. Last month,the company sold a total of 500 smartphones and made a total profit of $85,000.

Here's a word problem that uses a system of linear equations:

Sarah and John went to a coffee shop and ordered lattes and scones. Sarah ordered 2 lattes and 3 scones and paid $10. John ordered 3 lattes and 2 scones and paid $11.50. What is the cost of one latte and one scone?

Let x be the cost of one latte and y be the cost of one scone. We can set up a system of linear equations to solve for x and y:

2x + 3y = 10

3x + 2y = 11.5

Now, your partner can solve this system of equations using any method they prefer, such as substitution or elimination.

To solve the system of equations:

2x + 3y = 10

3x + 2y = 11.5

We can use elimination method, by multiplying the first equation by 2 and the second equation by -3 to eliminate y:

4x + 6y = 20

-9x - 6y = -34.5

Adding the two equations, we get:

-5x = -14.5

Dividing both sides by -5, we get:

x = 2.9

Substituting x = 2.9 into the first equation, we can solve for y:

2(2.9) + 3y = 10

5.8 + 3y = 10

3y = 4.2

y = 1.4

Therefore, one latte costs $2.9 and one scone costs $1.4.

The specific range depends on the material properties and the energy levels involved.

The minimum and maximum frequencies for the acoustic and optic modes depend on the specific system or material under consideration. However, I can provide some general information.

Acoustic Mode:

The acoustic mode refers to the propagation of sound waves or vibrations in a material. In a solid, the acoustic mode can have different types, such as longitudinal and transverse modes.

The minimum frequency for the acoustic mode is typically determined by the size and physical properties of the material. In general, it can be close to zero for macroscopic objects or materials with low elasticity.

The maximum frequency for the acoustic mode depends on factors such as the speed of sound in the material and the characteristic dimensions of the system. It can range from a few kilohertz to several gigahertz.

Optic Mode:

The optic mode is related to the interaction of light with a material. It typically refers to the vibrations of charged particles (such as electrons) in a solid or the oscillations of electric or magnetic fields associated with photons.

The minimum frequency for the optic mode is typically determined by the energy gap between electronic states in the material. For example, in a semiconductor, the minimum frequency is usually in the infrared range.

The maximum frequency for the optic mode is not strictly defined, as it can extend into the terahertz, infrared, visible, ultraviolet, X-ray, and even gamma-ray regions. The specific range depends on the material properties and the energy levels involved.

It's important to note that these frequency ranges are general guidelines and can vary depending on the specific system or material being studied.

y = x - 2(w + z).

Expressions can be made simpler by first enlarging any brackets, then multiplying or dividing any terms and, if necessary, using the rules of indices. Then, similar terms can be gathered by adding or subtracting them, and the expression is then rewritten.

By combining the terms those are similar, we can "collect the like terms" and make an algebraic expression simpler.

As we highlight a like terms, we has to include the sign next to the term and if appropriate identify the negative values.

The given formula is:

w = (x - y)/2 - z

To estimate the value of y.

Bring 'z' on the left of the formula.

w + z =  (x - y)/2

Now multiplying both sides by 2.

2(w + z) =  2*(x - y)/2

2(w + z) =  (x - y)

What is percentage?

Percentage is a way of expressing a number as a fraction of 100. It is denoted by the symbol "%". Percentages are commonly used to represent part of a whole or a proportion of a quantity.

At the end of 2010, the business had 140 stores in the United States.

By the end of 2016, the number of stores in the United States had increased by 60%. To find out how many stores there were at the end of 2016, we need to add 60% of the original number of stores to 140:

Number of stores at end of 2016 = 140 + 0.6*140 = 140 + 84 = 224

So there were 224 stores in the United States at the end of 2016.

If 1/14 of these stores were located in California, we can calculate the number of stores located in California as follows:

Number of stores in California = (1/14) * 224 = 16

Therefore, the number of stores located in California at the end of 2016 was 16, so the answer is (d) 16.

b. To find the predicted price for a 2000 square foot house, we substitute the size value into the equation: PRICE = 30.0 + 0.338 * SIZE. Therefore, the predicted price for a 2000 square foot house would be $30,000 + 0.338 * 2000 = $30,676.

c. If we had measured price in dollars instead of thousands of dollars, the estimated coefficient on size would decrease. For example, if the coefficient on size was 0.338 when price was measured in thousands of dollars, it might be 0.000338 when price is measured in dollars. This is because the change in the unit of measurement affects the magnitude of the coefficient.
