Answer:amount of decrease 290 ;numbers of chairs 5510

Step-by-step explanation:

Stablish the proportion 5800/100%=x/5% then solve for x. ; x=(5%/100%)*5800 = 290 which is the decrease. Then make the difference 5800-290 and you get 5510

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

The number of chairs decreased is 290.

The number of new chairs produced each month is 5510.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

We have,

Number of chairs produce in a month = 5800

5% decrease in production:

= 5% of 5800

= 5/100 x 5800

= 5 x 58

= 290

The number of new chairs produced each month:

= 5800 - 290

= 5510

Thus,

The number of chairs decreased is 290.

The number of new chairs produced each month is 5510.

Answer:

50.7

Step-by-step explanation:

Answer:

180m/s

STEP BY STEP EXPLANATION:

1m/s = 3600/1000 km/h

50m/s = 3600/1000 * 50

= 36 * 5

= 180m/s

4x – 2y=7

3x – 3y = 15

we want to keep y by eliminating the x

so we will Multiply the top equation by 3 and the bottom equation by 4.

we will get

12x - 6y = 21

12x - 12y = 60

we subtract the equations

12x - 6y - 12x - (-12y) = 21 - 60

6y = -39 and so on

Answer:

68mph to 134 mph

Step-by-step explanation:

We apply

Chebyshev's Theorem States:

At least 3/4 or 75% of data falls within 2 standard deviations from the mean - between μ – 2σ and μ + 2σ.

At least 8/9 or 88.89% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

From the question,

Mean = 101 miles per hour

Standard deviation = 11 miles per hour

We are to give an interval that will contain the speeds of at least eight ninths of the players serves

Hence, we apply the rule

At least 8/9 or 88.89% of data falls within 3 standard deviations from the mean - between μ - 3σ and μ + 3σ.

μ - 3σ

= 101 - 3(11)

= 101 - 33

= 68 miles per hour

μ + 3σ.

= 101 + 3(11)

= 101 + 33

= 134 miles per hour

Therefore, the interval is 68mph to 134 mph

32.5 ft^2

Step-by-step explanation:

All sides of a square have the same length.  Area would therefore be:

 (5.7 ft)(5.7 ft) = 32.5 ft^2

The true statement is that, the probability that 17% to 23% percent of all voters planned to vote is high

The percentage sample error (S) is given as:

S = 3%

The proportion (p) of the respondent is given as:

p = 20%

This means that the range (R) of the proportion is:

R = p ± S

This gives

R = 20% ± 3%

Expand

R = (20% - 3%, 20% + 3%)

Evaluate

R = (17%, 23%)

This means that the range is 17% to 23%

Step-by-step explanation:

If Caitlin were to win a huge sum of cash. In total, she has 49 bills. She adds up $1430. There are twenty and fifty-dollar bills available. The equation 20x + 50y = 1430 is the one that best describes the situation.

Equations are statements that affirm the equivalence of two expressions that are joined by the equals symbol "=". An equal sign ("=") links two expressions together to form an equation.

Given that Caitlin won a bag of cash, she has a total of 49 bills. She adds up to $1430. There are twenty and fifty-dollar notes available.

The system best represents the situation is,

20x + 50y = 1430

Thus, if Caitlin was to win a huge sum of cash. In total, she has 49 bills. She adds up to $1430. There are twenty and fifty-dollar bills available. The equation 20x + 50y = 1430 is the one that best describes the situation.

Answer:

Step-by-step explanation:

Look a the picture.

Draw the horizontal line y = 2.

Common point: (-4, 2).

Conclusion: f(x) = 2 → x = -4

From the graph at x = -4, then value of f(x) will be 2.

A graph can be defined as a pictorial representation or a diagram that represents data or values in an organized manner.

In the given graph, first we have to draw a line f(x)=2 i.e y=2

Draw the horizontal line y = 2.

We have to check where the horizontal line is meeting the line in graph.

Then we get a Common point at (-4, 2).

So x value is =-4 for f(x)=2 in the given graph.
