80 times what equals 44??

Answer:

cbe

Step-by-step explanation:

The angle whose measure is equal to the sum of the measures of ∠BAC and ∠BCA is ∠CBE, the correct option is B.

An angle is formed by two rays called the arms of the angle meeting at a common endpoint called the vertex of the angle.

The angle whose measure is less than 90 degree is called the acute angle, whose measure is equal to 90 degree is called right angle, the angle whose measure is greater than 90 degree is called obtuse angle.

The ∠BAC and ∠BCA are the interior angles of the triangle,

According to the theorem of exterior angle, The measure of the exterior angle is equal to the sum of the two opposite interior angles.

The sum of the angles, ∠BAC and ∠BCA is equal to the opposite exterior angle, i.e. ∠CBE

∠CBE =  ∠BAC + ∠BCA

Given:

This table shows the ratio of apples to oranges.

Apples      Oranges

   6                 10

   9                 15

  12                  ?

To find:

The missing value in the table of equivalent ratios.

Solution:

Let the missing value be x.

The ratios of apple and oranges are equivalent. So,

[tex]\dfrac{6}{10}=\dfrac{9}{15}=\dfrac{12}{x}[/tex]

[tex]\dfrac{3}{5}=\dfrac{3}{5}=\dfrac{12}{x}[/tex]

[tex]\dfrac{3}{5}=\dfrac{12}{x}[/tex]

On cross multiplication, we get

[tex]3\times x=12\times 5[/tex]

[tex]3x=60[/tex]

Divide both sides by 3.

[tex]x=20[/tex]

Therefore, the missing value is 20.

Answer:

a)The average salary, then, for accountants in Canada is $2352

b) The standard deviation of the salary, then, for accountants in Portugal is $388.2

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ,

where:

x is the raw score

μ is the population mean

σ is the population standard deviation.

a) Suppose you are told that an accountant in Canada who makes $2,646.00 has a z-score of +0.50 relative to other accountants in Canada and that the standard deviation of the salary of accountants in Canada is $588.00. The average salary, then, for accountants in Canada is _____.

z = (x-μ)/σ

z = 0.50, x =$2,646.00 μ = ?? σ = $588

Hence,

0.50 = 2,646 - μ/588

0.50 × 588 = 2,646 - μ

294 = 2,646 - μ

μ = 2,646 - 294

μ = $2352

Therefore, the average salary, then, for accountants in Canada is $2352

b) Suppose you are also told that an accountant in Portugal who makes $2, 329.40 has a z-score of +2.00 relative to other accountants in Portugal and that the mean of the salary of accountants in Portugal is $1, 553. The standard deviation of the salary, then, for accountants in Portugal is _____ .

z = (x-μ)/σ

z = 2, x = $2,329.40 μ =$1,553 σ = ?

2 = ($2,329.40 - $1,553)/σ

2σ = $2,329.40 - $1,553

σ = $2,329.40 - $1,553/2

σ = $776.4 /2

σ = $388.2

Therefore, the standard deviation of the salary, then, for accountants in Portugal is $388.2

Answer:

−5m² + 7m + 8

Explanation:

−m² + 6 − 4m² + 7m + 2

= −m² + 6 + −4m² + 7m + 2

[ Combine Like Terms ]

= −m² + 6 + −4m² + 7m + 2

= −5m² + 7m + 8

Answer:

Step-by-step explanation:

You are to make 5 assemblies.

Each assembly requires the use of 1 Type A bolt.

To make the 5 assemblies, you need 5 Type A bolts.

The container of bolts has a total of 60 bolts.

The focus - Type A bolts - is 20 out of this 60.

The probability of obtaining a Type A bolt at all, is 20/60, which is = 1/3

(A) What is the probability of taking the exact number of Type A bolts you need for your 5 assemblies, if you randomly take 10 bolts from the container?

- The exact number of Type A bolts you need for the 5 assemblies is 5

1/3 × 5/10 =  5/30 =  1/6 =  0.167

(B) What is the probability of taking/having less than 5 Type A bolts out of the randomly selected 10 bolts? The solution is to sum up the following:

1/3 × 4/10 = 0.133

1/3 × 3/10 = 0.1

1/3 × 2/10 = 0.067

1/3 × 1/10 = 0.033

1/3 × 0/10 = 0

TOTAL = 0.333

Step-by-step explanation:

Let the smaller number be x.

So, according to Question,

the larger number will be 1+4x.

Now, sum of the numbers is 61, like this:-

[tex]1 + 4x + x = 61[/tex]

[tex]5x = 61 - 1[/tex]

[tex]5x = 60[/tex]

[tex]\tt{x = \dfrac{60}{5}}[/tex]

[tex]\boxed{\tt{x = 12}}[/tex] is the required Answer.

Step-by-step explanation:

Given parameters:

Equation of the line is y = -[tex]\frac{1}{2} x[/tex] + 8

Unknown:

Slope of line parallel to this line = ?

Slope of line perpendicular = ?

Solution:

A line parallel to this line will have the same slope with it.

A line perpendicular will have the negative inverse of this slope;

Slope of line  = - [tex]\frac{1}{2}[/tex]

Slope of line parallel to this line = [tex]-\frac{1}{2}[/tex]

Slope of line perpendicular = negative inverse = -( -([tex]\frac{1}{\frac{1}{2} }[/tex]))   = 2

So, the slope of line parallel to this line is - 1/2 and that perpendicular is 2

The correct answer is 24654.29

Step-by-step explanation:

Identify the values of each variable in the formulas. Remember to express the percent as a decimal.

For quarterly compounding, n=4. There are 4 quarters in a year.

Substitute the values in the formula.

A=15,000(1+0.054)4⋅10

Compute the amount. Be careful to consider the order of operations as you enter the expression into your calculator.

A=$24,654.29

Answer:

1- Add 15 to both sides

2- 3x - 15 = 27

3- Already answered

4- 3x = 42

5-  Divide both sides by 3

    x = 14
