What is 3.761 in expanded form

Answer:

x = -11

Step-by-step explanation:

The sum of the angles of a triangle add to 180

x+50  + 72+  x+80   = 180

Combine like terms

2x + 202 = 180

Subtract 202 from each side

2x+202-202 = 180-202

2x =-22

Divide each side by 2

2x/2 = -22/2

x = -11

Step-by-step explanation: Write down the whole number amount, for example: 500. Calculate the equation. The result is the decimal equivalent of the percentage. Multiply the decimal equivalent of the percentage by 100; or move the number's decimal point over two places to the right.

Complete question is;

Statistics can help decide the authorship of literary works. Sonnets by a certain Elizabethan poet are known to contain an average of 8.88 new words (words not used in the poet's other works). The standard deviation of the number of new words is 3. Now a manuscript with 6 new sonnets has come to light, and scholars are debating whether it is the poet's work. The new sonnets contain an average of 12.4 words not used in the poet's known works. We expect poems by another author to contain more new words, so to see if we have evidence that the new sonnets are not by our poet we test the following hypotheses.

H0 : µ = 8.88 vs Ha : µ > 8.88

Give the z test statistic and its P-value. What do you conclude about the authorship of the new poems? (Let a = .05.)

Use 2 decimal places for the z-score and 4 for the p-value.

a.What is z ?

b.The p-value is greater than ?

c. What is the conclusion? A)The sonnets were written by another poet or b) There is not enough evidence to reject the null.

Answer:

a) z = 2.87

b) P-value ≈ 0.0021

c) The sonnets were written by another poet

Step-by-step explanation:

We are given the hypothesis as;

Null hypothesis; H0 : µ = 8.88

Alternative hypothesis; Ha : µ > 8.88

We are also given;

Sample size; n = 6

Population Standard deviation; σ = 3

Sample mean; x¯ = 12.4

a) formula for z - value is;

z = (x¯ - µ)/(σ/√n)

z = (12.4 - 8.88)/(3/√6)

z = 2.87

b) we are given the significance value as α = 0.05.

From online p-value from z-score calculator attached and using z = 2.87; one tail distribution; α = 0.05, we have;

P-value = 0.002052

Approximating to 4 decimal places;

P-value ≈ 0.0021

c) The p-value is less than the significance level, thus we react the null hypothesis and conclude that the sonnets were written by another poet

A growth mindset is an idea that people are born with certain characteristics and can't change. A growth mindset allows a person to believe they can change themselves, and that abilities and intelligence can be developed over time. A growth mindset helps you learn that mistakes are stepping stones and that you aren't defined as some characteristic (like "dumb").

.55×78=42.9

78+42.9

=120.9 round off 121

Answer: 120.9 I believe.

Step-by-step explanation:

55% of 78 is 42.9.

(55 x 78 over 100 = 42.9)

Therefore take 78 + 42.9.

120.9

Step-by-step explanation:

Answer:

The line y+2x=b is perpendicular to a line that passes through the origin. If the two lines intersect at the point (k+2,2k)

Step-by-step explanation:

that should be right

The value of k is 2/3.

We have,

To determine the value of k, we need to find the equation of the line passing through the origin that is perpendicular to the line y + 2x = b.

The given line, y + 2x = b, can be rewritten in slope-intercept form

(y = mx + c) by solving for y:

y = -2x + b

Since the line passing through the origin is perpendicular to this line, its slope will be the negative reciprocal of the slope of the given line.

The given line has a slope of -2, so the perpendicular line will have a slope of 1/2.

Using the point-slope form (y - y1 = m(x - x1)) with the point (k + 2, 2k), we can write the equation of the perpendicular line passing through the origin as:

y - 0 = (1/2)(x - 0)

y = (1/2)x

To find the value of k, we equate the y-values of the two lines at the point of intersection:

(1/2)x = 2k

x = 4k

Since the x-coordinate of the point of intersection is k + 2, we can set it equal to 4k and solve for k:

k + 2 = 4k

2 = 3k

k = 2/3

Therefore,

The value of k is 2/3.

Answer:

The answer is 35

Step-by-step explanation:

First of all, note that 56 is the same as 56/1 since 56 divided by 1 is 56. Therefore, start by setting up the problem like this:

Step 1: 56/1 x 8/5 =

Step 2: Multiply the numerators together (56 x 8 = 448) and multiply the denominators together (1 x 5 = 5) and make it into one fraction like so 448/5 Step 3: Convert the improper fraction above to a mixed number to get the answer: 89 3/5

That's it! Now you know how to calculate 56 times 8:5.

The price of the pen is "12", and the cost price of 1000 pens is "12000".

Assume the number of Pens[tex]= x[/tex]

commission price of 1000 Pens[tex]=1000 x[/tex]

The selling price of Pens:

  [tex]=\frac{1000\times 115x}{100}\\\\ ={10\times 115 x}{}\\\\= 1150x[/tex]

Commission price on Purchase:

[tex]= \frac{1000\times 1 x}{100}\\\\= \frac{10\times 1 x}{1}\\\\= 10x[/tex]

commission price on sales:

[tex]=\frac{1150x \times 3}{100}\\\\=\frac{115 x \times 3}{10}\\\\=\frac{345 x }{10}\\\\=34.5\ x[/tex]

Calculating the total commission:

[tex]\to 10x+34.5x=44.5x=534\\\\\to 44.5x=534\\\\\to x = \frac{534}{ 44.5}=12[/tex]

Therefore, the agent buys a pen at 12 rupees and the cost price of 1,000 pens is 12000.

Answer:

15,003 and Highest Point

Step-by-step explanation:

The highest point is at a positive 14,864 feet so we will use the number 14, 864.

The lowest is at a negative (below sea level) 141, so we will use the number -141.

The difference between them means that you subtract.

14,862-(-141)= x

Note that there is a double negative so it is positive.

14862+141=15,003 feet difference between them.

A city at 7642 above sea level is:

7642-14862=7222 feet away. The city is 7222 feet away from the highest point.

7642--141=7783 feet away. The city is 7783 feet away from the lowest point.

7222 is less than 7783, so the city is closest to the highest point.

Answer:

The difference is 15,005 and for the second part its closer to the highest point

Answer:

$56.51

Step-by-step explanation:

Given parameters:

Cost price by the store = $49.14

Amount of mark up = 50%

Unknown:

Make- up price  = ?

Solution:

Since the price was increased by 50% more, to find the mark up price, we can find 50% of the cost price and add the value to the cost price.

Also;

 Make-up price  =( 1 + [tex]\frac{50}{100}[/tex] ) x $49.14

                           = 1.15 x $49.14

                            = $56.51
