Step-by-step explanation:

Given quadratic equation:

[tex]2x^2-4x+3=0[/tex]

When completing the square for a quadratic equation in the form ax²+bx+c=0, first move the constant to the right side of the equation:

[tex]2x^2-4x=-3[/tex]

Divide both sides of the equation by the coefficient of x²:

A high school soccer team is going to Columbus, Ohio to see a professional soccer game. A coordinate grid is superimposed on a highway map of Ohio. The high school is at point (2, 5) and the stadium in Columbus is at point (8, 13). The map shows a highway rest stop halfway between the cities. What is the distance between the high school and the stadium? (One unit = 8.6 miles.)

Answers

To find the distance between the high school and the stadium, we need to use the distance formula. The distance formula is given by the following equation:

d = sqrt((x2 - x1)^2 + (y2 - y1)^2)

where (x1, y1) is the coordinates of the starting point, and (x2, y2) is the coordinates of the ending point.

In this case, the starting point is the high school, which is located at the coordinates (2, 5), and the ending point is the stadium in Columbus, which is located at the coordinates (8, 13). Plugging these values into the distance formula, we get:

d = sqrt((8 - 2)^2 + (13 - 5)^2)

d = sqrt(6^2 + 8^2)

d = sqrt(36 + 64)

d = sqrt(100)

d = 10

Therefore, the distance between the high school and the stadium is 10 units. Since 1 unit is equal to 8.6 miles, the distance between the high school and the stadium is 86 miles.

It's worth noting that the rest stop is located halfway between the high school and the stadium. This means that the distance from the high school to the rest stop is 86/2 = 43 miles, and the distance from the rest stop to the stadium is also 43 miles. This can be verified by using the distance formula to find the distance between the rest stop and the high school, and then between the rest stop and the stadium.

question what is the hundredths digit of the decimal z ? (1) the tenths digit of 100z is 2. (2) the units digit of 1,000z is 2.

Answers

We can infer that those assertions do not provide us with adequate details on the hundredths in the decimal system.

What do we mean by a decimal?

The decimal numeral system is widely used to express both integer and non-integer numbers.

The Hindu-Arabic number system has been expanded to include non-integer values.

The way of representing numbers in the decimal system is known as decimal notation.

(1) Since 2 is the eleventh digit of 100z, we may begin writing 100z.

10z = 100(a.bcd)

The decimal point is moved two places to the right by multiplying by 100, giving us the value of:

10z = 100abc.d

Then we shall have d = 2 if the tenths of 100z equal 2.

We have so far: z = a.bc2

(2) Since 1000z's units digit is 2, we may begin writing 1000z.

1000z = 1000a.bc2

We need to move the decimal point three places to the right so that we have order to multiply by 1000:

1000z = abc2

As a result, we can now confirm that the unit digit is actually 2.

However, the number is as follows: z = a.bc2

Therefore, we can infer that those assertions do not provide us with adequate details on the hundredths in the decimal system.

Answers

The number of children take greek and hebrew = 2

In this question, we have been given that in a class of 30 children, 20 take latin, 14 take greek, and 10 take hebrew.

So, n(s) = 30

Let set a: children taking Latin language

n(a) = 20

set b: children taking Greek language

n(b) = 14

set C: children taking Hebrew language

n(c) = 10

no child takes all three languages

⇒ n(a ∩ b ∩ c) = 0

And eight children take no language

⇒ n(S) -  n(a ∪ b ∪ c) = 8

So, n(a ∪ b ∪ c) = 8

This means, 22 children taking languages.

Of those 22 kids, 14 take Greek and 10 take Hebrew.

14+10 = 24

This means, at least 2 children must taking Greek and Hebrew.

Since no child takes all three languages, the children taking Greek and Hebrew can't be taking Latin. Since 20 of the 22 kids are taking Latin, that means at most 2 are taking Greek and Hebrew.

Writing 1/3 as a number's exponent is another method to represent a cube root.

The given equation

z³ = 8

The number 8 can be written as

8 = 2 × 2 × 2

= 2³

So,

z³ = 2³

So, comparing both sides, we get

z = 2

This is the solution to the equation.

Answers

Among the following, the population mean u = (upper confidence limit) + (lower confidence limit) is not derived from the confidence interval.

A confidence interval is defined as the range of values that we observe in our samples and for which  we expect to find the value that accurately reflects the population.

In frequentist statistic, a confidence interval is a range of estimates for an unknown parameter.    

To find a confidence level for a data set by taking half of the size of the confidence interval, multiplying it by the square root of the sample size and then dividing by the sample standard deviation.

Confidence level refers to the percentage of probability,or certainty, that the confidence interval would contain the true population parameter when you draw a random sample many times. The most common confidence levels are 90%, 95% and 99%.

in order to fairly set flat rates for auto mechanics, a shop foreman needs to estimate the average time it takes to replace a fuel pump in a car. how large a sample must he select if he wants to be 99% confident that the true average time is within 15 minutes of the sample average? assume the standard deviation of all times is 30 minutes.

Answers

The value of n is 25  according to standard deviation in the question.

What is standard deviation?

Standard Deviation is a measure that shows what quantity variation (such as unfold, dispersion, spread,) from the mean exists. the quality deviation indicates a “typical” deviation from the mean. it's a well-liked live of variability as a result of it returns to the first units of live of the info set.

Main body:

s = 30 minutes

C.I. = 99%

mean = 15 minutes

z value for 99% = 2.58

mean = z*s/√n

15  = 2.58 * 30 / √n

√n = 5.06

n = 25

Hence the value of n is 25 .

translate each of the following multiplicative expressions into its additive counterpart. assume that the operation is commutative. a. a2b3 b. a22(b21c)2 c. (ab2)23c2 5 e

Answers

The additive counterpart of given expressions are (2a+3b), -2a+2(-b+c), and -3(a+2b)+2c=0.

When two numbers may be added together or multiplied, regardless of the order in which they are entered, the result is said to be commutative. There are different formulas available for the conversion of multiplicative expressions to their additive counterparts.

a) The first expression is a²b³. This expression is written as aabbb. This is of the form ab and its corresponding additive counterpart is of the form a+b.

Then, a+a+b+b+b=2a+3b.

b) The second expression is a⁻²(b⁻¹c)². This expression is of the form a⁻¹ and its corresponding additive counterpart is of the form -a.

Then,

[tex]\begin{aligned}a^{-2}(b^{-1}c)^2&=a^{-1}a^{-1}(b^{-1}c)(b^{-1}c)\\&=-a-a-b+c-b+c\\&=-2a+2(-b+c)\end{aligned}[/tex]

c) The third expression is (ab²)⁻³c²=e. This expression is first expanded as, (ab²)⁻¹(ab²)⁻¹(ab²)⁻¹c²=e. Using property, (xy)⁻¹=y⁻¹x⁻¹.

Then,

[tex]\begin{aligned}((b^2)^{-1}a^{-1})((b^2)^{-1}a^{-1})((b^2)^{-1}a^{-1})c^2&=e\\(b^{-2}a^{-1})(b^{-2}a^{-1})(b^{-2}a^{-1})c^2&=e\end{aligned}[/tex]

Also, the additive identity to e is zero. And, aⁿ=na.

Then,

(-2b-a)+(-2b-a)+(-2b-a)+2c=0

Simplifying we get,

-3(a+2b)+2c=0.

The answers are  (2a+3b), -2a+2(-b+c), and -3(a+2b)+2c=0.
