1945 men and 2849 women register to audition for a singing competition. The number of participants who are not successful in their auditions what’s five times the number of those who are successful. There are 799  participants were successful.

The successful  participants  can be calculate by solving a linear equation as follows

First, it's crucial to understand linear equations.

Equation connects the two algebraic expressions with an equal to sign to demonstrate the equality between the two algebraic expressions.

Linear equations are those with one degree.

In this case, a linear equation must be resolved.

1945 for the men's total

Women are present in 2849.

Participants in total: 1945 + 2849 = 4794

Let x be the proportion of participants that were successful.

Men who failed were 5 times as numerous.

Participants in total: 5x + x = 6x

Due to the issue,

The linear formula is

6x = 4794

x = 4794/6

x = 799

799 of the participants had success.

Step-by-step explanation:

8+2=10

10-4=6

3-5=-2

6 + -2=4

Answer:

(- 2, 16 )

Step-by-step explanation:

y = 8x + 32 → (1)

y = - 8x → (2)

substitute y = 8x + 32 into (2)

8x + 32 = - 8x ( add 8x to both sides )

16x + 32 = 0 ( subtract 32 from both sides )

16x = - 32 ( divide both sides by 16 )

x = - 2

substitute x = - 2 into either of the 2 equations and evaluate for y

substituting into (2)

y = - 8(- 2) = 16

solution is (- 2, 16 )

Answer:

in pre algebra

you have to do the math so that you

put x on one side of the equal sign &

the numbers on the other side

x = the answer

for  

1.

2x - 7 = 3 (x - 4)

multiply 3 with  (x - 4)

you do this by

multiplying 3 with x and

multiplying 3 with- 4

2x - 7 = 3 (x - 4)

2x - 7 = 3x - 12

put x on one side of the equal sign & the numbers on the other side

2x - 7 = 3x - 12

-2x     = -2x    

2x -2x = 0 & 7 comes down.

3x -2x = 1x & - 12  comes down

0 - 7 = 1x - 12

add 12 on both sides

- 12 + 12 = 0

- 7 + 12 is the same as 12 - 7 which is 5

0 + 5  =  1x - 0

you dont have to show the 0

& if its 1x you you dont have to show the 1

5 = x or x = 5

2.

5x + 3 < 4x - 1

for now treat < like an equal sign

in real life math the symbols  < & > mean at least or at most

which helps with things about money

5x + 3 < 4x - 1

subtract -4x on both sides

5x + 3 < 4x - 1

-4x         -4x

1x + 3 < 0 - 1

subtract 3 on both sides

1x + 3 < 0 - 1

1x - 3 < 0 - 3

x < - 3

answer means the answer is

The standard error for the sample was 0.13 when "for the 25 students, the standard deviation of grade points was 0.65 and the mean was 2.89."

The standard deviation of a statistic's sampling distribution, or an estimate of that standard deviation, is the statistic's standard error. The term "standard error of the mean" is used when referring to a statistic that is the sample mean. By dividing the standard deviation by the square root of the sample size, the standard error is determined. By taking into account the sample-to-sample variability of the sample means, it provides the precision of a sample mean.

Here,

The standard error=standard deviation/√number of samples

=0.65/√25

=0.65/5

=0.13

Answer: A and B

Step-by-step explanation:

The shape is moving from right to left and down

Using the prime factorization method, we can find the greatest common divisor (GCD) and least common multiple (LCM) for the given numbers.

a. For the numbers 11 and 19:

To find the GCD, we compare their prime factorizations. Since 11 and 19 are both prime numbers, their only common factor is 1.

Therefore, the GCD is 1.

To find the LCM, we multiply the numbers together since they have no common factors. Hence, the LCM of 11 and 19 is 11 * 19 = 209.

b. For the numbers 140 and 320:

To find the GCD, we factorize both numbers into their prime factors. The prime factorization of 140 is 2² * 5 * 7, and the prime factorization of 320 is 2⁶ * 5. To find the GCD, we take the lowest exponent for each common prime factor, which is 2² * 5 = 20. Therefore, the GCD of 140 and 320 is 20.

To find the LCM, we take the highest exponent for each prime factor present in the numbers. Thus, the LCM of 140 and 320 is 2⁶ * 5 * 7 = 2240.

In summary, for the numbers 11 and 19, the GCD is 1 and the LCM is 209. For the numbers 140 and 320, the GCD is 20 and the LCM is 2240.

Answer:

30°, 60° and 90°

Step-by-step explanation:

Given the expression Arccos (√3/2)=β, we can use the expression to calculate one of the acute angles in a right angled triangle.

Note that a right angled triangle is made up of two acute angles and a right angled (90°)

Let's get one of the acute angles first

If Arccos (√3/2)=β

β = cos^-1 √3/2

β = 30°

This shows that one of the acute angles is 30°

To get the third angle, we know that sum of angles in a triangle is 180° and since we already know two of the angles, i.e 90° and 30°, we can get the third angle.

90+30+x = 180

120+x = 180

x = 180-120

x = 60°

All the angle measurement for the right angled triangle are 30°, 60° and 90°

(1) 6.1 x 10⁷ is approximately 2.9 x 10¹¹ times larger than 2.1 x 10⁻⁴ as estimated.

(2) 1.9 x 10⁻⁸ is approximately 4.5 x 10⁴ times larger than 4.2 x 10⁻¹³ as estimated.

To estimate how many times larger 6.1 x 10⁷ is than 2.1 x 10⁻⁴, we can divide the two numbers:

6.1 x 10⁷ ÷ 2.1 x 10⁻⁴

= 6.1 x 10⁷ ÷ (2.1/10⁴)

= 6.1 x 10⁷ x (10⁴/2.1)

≈ 2.9 x 10¹¹

To estimate how many times 1.9 x 10⁻⁸ is than 4.2 x 10⁻¹³, we can divide the two numbers:

1.9 x 10⁻⁸ ÷ 4.2 x 10⁻¹³

= 1.9/4.2 x 10⁵

a. The standard error of the mean for n = 25 is 3 cm

b.  The standard error of the mean for n = 100 is 1.5 cm.

Agronomist measured the height of n corn plants. If the mean height is 220 cm and the standard deviation is 15 cm, then we can calculate the standard error of the mean for n = 25 and n = 100 as shown below -

(a) For n = 25:

    If n = 25, then the formula for calculating the standard error of the mean is as follows -

    Standard Error of the Mean = (Standard Deviation / √n)

    Given,

    Standard deviation (σ) = 15 cm

    Number of samples (n) = 25 cm

    We can calculate the standard error of the mean as follows -

    Standard Error of the Mean = (Standard Deviation / √n)

                                                   = (15 / √25)

                                                   = 3

    Hence, the standard error of the mean for n = 25 is 3 cm.

(b) For n = 100:

    If n = 100, then the formula for calculating the standard error of the mean is as follows -

    Standard Error of the Mean = (Standard Deviation / √n)

    Given,

    Standard deviation (σ) = 15 cm

    Number of samples (n) = 100 cm

    We can calculate the standard error of the mean as follows -

    Standard Error of the Mean = (Standard Deviation / √n)

                                                   = (15 / √100)

                                                   = 1.5

    Hence, the standard error of the mean for n = 100 is 1.5 cm.

Answer:

Step-by-step explanation:

By the Isosceles Triangle Theorem, if 2 sides of a triangle are congruent to each other, than the angles opposite those sides are also congruent. We see by the markings on the triangle that WX and WY are congruent. That means that angle Y (which is across from WX) and angle X (which is across from WY) are the same measure. We can set them equal to each other  because of this:

6y - 2 = 4x + 20

But we have a problem because we have 2 unknowns.

Let's try this out: the Triangle Angle-Sum Theorem says that all the angles of a triangle have to add together to equal 180. That means that

52 + 6y - 2 + 4x + 20 = 180.

But we STILL have a problem with those 2 unknowns. BUT...

If angle X and angle Y are the same, then we don't need both 6y - 2 AND 4x + 20.  We only need 1 of those multiplied by 2 because they're the same measure. Changing things up a bit to reflect that:

52 + 2(4x + 20) = 180 and

52 + 8x + 40 = 180 and

8x = 88 so

x = 11.

That means that

4(11) + 20 = 64 which is the measure of both angles X and Y.

Let's check:

64 + 64 + 52 better equal 180. And it does, so we're good.

The value of x is found this way:

4x + 20 = 64 and

4x = 44 so

x = 11 which we already knew. Now for y:

6y - 2 = 64 and

6y = 66 and

y = 11 also.

The amount of money you need to save today is $4,926.

To calculate the amount of money you need to save today, you can use the formula for calculating future value with compound interest:

Future Value = Present Value * \((1 + Interest Rate)^T^i^m^e\)

In this case, the future value is $5,000, the interest rate is 1.75% (or 0.0175), and the time is 1 year. We need to solve for the present value.

Rearranging the formula, we have:

Present Value = Future Value /\((1 + Interest Rate)^T^i^m^e\)

Plugging in the values, we get:

Present Value = $5,000 / \((1 + 0.0175)^1\)

Present Value = $4,926

Therefore, you need to save $4,926 today in order to have $5,000 one year from now.
