Six-four million, one hundred eighty-six thousand, three hundred square miles in standard form

Answers

Answer 1

Answer:

64,186,300

Step-by-step explanation:

Six-four million - 64 million.

One hundred eighty six thousand - 186,000

You won't have space for the zeros, so you remove them.

And last, three hundred - 300.

So, now combine all of the numbers.

Your answer is 64,180,300.

Hope it helps!

Answer 2

Answer:

Final answer:

The number six-four million, one hundred eighty-six thousand, three hundred is written as 64,186,300 in standard form.

Explanation:

The student is asking for a numerical representation of a written number, specifically six-four million, one hundred eighty-six thousand, three hundred. In standard form, this would be written as 64,186,300. The "million" denotes six zeros following the 64, the "thousand" indicates three zeros following the 186, and the "three hundred" is written as 300 at the end. So, in simpler terms, the number is written as 64,000,000 + 186,000 + 300 = 64,186,300.

Answer:

The length of the guy wire is 17ft.

Step-by-step explanation:

$c = \sqrt{a^(2)+b^(2) }$

a = 15ft

b = 8ft

c = $\sqrt{15^(2) + 8^(2) }$

c = $√(225 + 64)$

c = $√(289)$

c = 17

The length of the guy wire is 17ft.

Answer:

Step-by-step explanation:

c=15×15+8×8

c=225+64

c=289=17

Write the expanded form 0.45 in this way using fractions and using decimals

Answers

Using fractions, 0.45 can be written as $(3)/(10)$ + $(3)/(20)$ . Using decimals, 0.45 can be written in the form as 0.30 + 0.15.

What is Decimal Numbers?

Decimal number system is applicable for both integers as well as non integers. Decimal number include a whole number part and a decimal part separated using decimal point.

Fractions are the numbers which are part of a whole.

All decimal numbers can be written as fractions and fractions can be written in the form of decimal numbers.

The given number is 0.45.

0.45 can be written as $(45)/(100)$ .

$(45)/(100)$ can be expanded in various ways like (40 + 5)/100, (42 + 3)/100 and so on.

$(45)/(100)$ can be written in one of the form as $(30)/(100)$ + $(15)/(100)$ .

When simplified, $(30)/(100)$ simplified to $(3)/(10)$ and $(15)/(100)$ simplified to $(3)/(20)$ .

So 0.45 = $(3)/(10)$ + $(3)/(20)$ .

Now, in the decimal form, $(3)/(10)$ = 0.3 and $(3)/(20)$ = 0.15

So, 0.45 = 0.3 + 0.15

Hence 0.45 can be expanded in the fractional form as $(3)/(10)$ + $(3)/(20)$ and in the decimal form as 0.3 + 0.15.

For the equation y = 2x2 - 5x + 18, choose the correct
application of the quadratic formula.

Answers

Answer:

Option (2)

Step-by-step explanation:

For a quadratic equation,

ax² + bx + c = 0

roots of this equation can be determined by using quadratic formula,

x = $(-b\pm√(b^2-4ac))/(2a)$

Comparing this quadratic equation with the given equation,

y = 2x² - 5x + 18 = 0

a = 2

b = (-5)

c = 18

By substituting these values in the given formula,

x = $(5\pm√((-5)^2-4(2)(18)) )/(2(2))$

Therefore, Option (2) will be the answer.

(a) For a normal distribution, find the z-score that cuts off the bottom 55.76% of all the z-scores. Round to 2 decimal places after the decimal point. answer: (b) For a normal distribution, find the z-score that cuts off the top 77.52% of area. Round to 2 decimal places after the decimal point. answer:

Answers

Answer:

a) Z = 0.15

b) Z = -0.76

Step-by-step explanation:

Problems of normally distributed samples are solved using the z-score formula.

In a set with mean $\mu$ and standard deviation $\sigma$ , the zscore of a measure X is given by:

$Z = (X - \mu)/(\sigma)$

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

(a) For a normal distribution, find the z-score that cuts off the bottom 55.76% of all the z-scores.

Bottom 55.76% of the scores are the z-scores with a pvalue of 0.5576 and less. So the z-score that cuts off these scores is Z when X has a pvalue of 0.5576, which is Z = 0.145, rounded to two decimal places, Z = 0.15.

(b) For a normal distribution, find the z-score that cuts off the top 77.52% of area.

The top 77.52% of the scores are the z-scores with a pvalue of 1-0.7752 = 0.2248 and higher. So Z = -0.764 and higher. So the value that cuts off the top 77.52% is Z = -0.76.
