which expressions represents a quadratic expression in factored form

Step-by-step explanation:

3.14

To round to the nearest hundredth, we therefore need to look at the digit immediately to its right—in other words, the 1 in the thousandths place. Since that number is less than 5, we need to round down—which gives us a rounded value of pi equal to 3.14

Answer:

32,800 litres

Step-by-step explanation:

V=l*w*h

V=4*2*4.8

V=38.4 cubic meters

38.4 cubic meter -> 38,400 litres

38,400/4=9,600

9,600*3=28,800

28,800+4,000=32,800

Answer:

Owen has enough to make 3 1/2 of pancake mix.

Step-by-step explanation:

Since the ratio is 1/8 cup of oil per cup of mix and Owen has 1/2 a cup of mix, he has enough to cover the 3 cups of mix since that would be 3/8 cups of oil. He has enough to cover 1/2 a cup as well because that'd be 1/16 cup of oil.

Step-by-step explanation:

An alternate exterior angle pair would have to be on the outside and be on opposite sides of the same line (like 5 and 11).

Angles 5 and 11, and angles 4 and 6 are pairs of alternate exterior angles.

Orientation of the one line with respect to the horizontal or other respective line is known as a measure of orientation and this measure is known as the angle.

Here,
Alternate exterior angles are angles that are located on opposite sides of the transversal (a line that intersects two other lines) and outside of the two lines being intersected. They are equal in measure.

Thus, Angles 5 and 11, and angles 4 and 6 are pairs of alternate exterior angles.

Answer:

1 do the division by a draw of their names into 2 teams

2 there might be one group with a higher age and thus a lower chance of being cured and you should know all variables and have control over the project

Step-by-step explanation:

Answer:

1. There are multiple methods to choosing randomly from a selection. One instance could be choosing names from a hat.

2. Dividing the groups randomly allows for an equal and fair distribution of people for the control and variable groups. The 50 people receiving the drug are the variable group, while the other 50 receiving the placebo are the control group.

Step-by-step explanation:

Random selection is used in testing in order to assure the lack of bias from researchers. In real trials, random selection would likely be done through the company's own software, or an Excel spreadsheet.

Random selection is also used in order to remove lurking variables. An example of a lurking variable could be shown as follows:

A researcher is studying a connection between heart disease and cholesterol intake. Aspects unrelated to the study could still have an effect on the quality of the results, like whether people in the groups smoked or was very stressed. Random distribution assists in removing any lurking variables - and if it can't fully remove them, it will at least distribute them fairly across the control and variable groups.

Step-by-step explanation:

Jordan's monthly mortgage payment will be $805.23.

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.

To calculate Jordan's monthly mortgage payment, we can use the formula for a fixed-payment loan:

M = P [ i(1 + i)^n ] / [ (1 + i)^n – 1 ]

where:

M = monthly mortgage payment

P = the principal, which is the amount borrowed

i = the monthly interest rate, which is the annual interest rate divided by 12

n = the number of monthly payments, which is the loan term in years multiplied by 12

In this case,

the principal (P) is $150,000,

the annual interest rate is 5%,

the loan term is 30 years,

and the monthly interest rate (i) can be calculated as:

i = 5% / 12 = 0.00417

n = 30 years * 12 months/year = 360 months

Substituting these values into the formula, we get:

M = 150000 [ 0.00417(1 + 0.00417)³⁶⁰] / [ (1 + 0.00417)³⁶⁰ – 1 ]

Simplifying this expression, we get:

M = $805.23

Therefore, Jordan's monthly mortgage payment will be $805.23.

x = 5[tex]\sqrt{3}[/tex]

Step-by-step explanation:

Using the sine ratio in the right triangle and the exact value

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex]

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{x}{10}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

2x = 10[tex]\sqrt{3}[/tex] ( divide both sides by 2 )

the answer is 11 (i think)

Step-by-step explanation:

Answer:

A couple of questions first:

Are we going to divide the candy box equally between those 2,3 or 7 person at one event- (at the same time )?

Are there 12 persons to take into consideration and that each gets the same number of candy pieces?

Are the 3 persons (and the other 2 as well) -different individuals from those who are the 7 referred to . If not then we have to consider 2 more persons.

So does the equal division of candy pieces have to be made between a minimum of 7, 10 or 12 individuals (2+3+7)?

The lowest common denominator is going to be 42. ( 2 x 3 x 7) Therefore seven persons would each get 6 pieces.)

But if the 2 and 3 people are diffèrent persons than the 7 , they will get an equal share ie. 6 pieces each, as well!

2 x 6 = 12

3 x 6 = 18

7 x 6 = 42

So, the box would have to contain at least 72 pieces of candy/ /chocolates or 6 dozens. And every one of the 12 would be happy with his 6 chocolates.

Comment on sequences and series

The sequences we commonly study are "arithmetic" and "geometric." Each of these has an explicit formula for the n-th term, based on the first term and the common difference or ratio. Similarly, each series (sum of terms of a sequence) also has a formula. That's 4 formulas to keep track of; not difficult. One of them, the formula for the n-th term of a geometric sequence, is shown above.
