how many solutions does the equations 3(x+2)-10+4x-6x have?

Answer:

0.1849 = 18.49% probability of making 2 sales in 100 calls

Step-by-step explanation:

For each call, there are only two possible outcomes. Either it is a success, or it is not. The probability of a call being a success is independent of any other call. This means that we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.

[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]

And p is the probability of X happening.

Probability of success is 1/100

This means that [tex]p = \frac{1}{100} = 0.01[/tex]

What is the probability of making 2 sales in 100 calls?

This is P(X = 2). So

[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]

[tex]P(X = 2) = C_{100,2}.(0.01)^{2}.(0.99)^{98} = 0.1849[/tex]

0.1849 = 18.49% probability of making 2 sales in 100 calls

Answer:

2 and 3  

Step-by-step explanation:

2) If two polygons are similar, the ratio of their areas is equal to the square of the ratio of their corresponding sides. 

side ratio:  1/4-------   area ratio: 1²/4²  =  1/16   = 1:16 ratio

3)If two polygons are similar, then the ratio of their perimeters is equal to the ratios of their corresponding side lengths.

The ratio of the perimeters is the same as the scale factor.

 scale 1:4

9514 1404 393

Answer:

  49.5 ft

Step-by-step explanation:

The diagonal of a square is √2 times its side length. This means the length of the walkway will be ...

  (35 ft)√2 ≈ 49.5 ft . . . walkway length

Answer:

1/12

Step-by-step explanation:

Given the following :

Actual height of pyramid = 24 ft

Dimension of scaled model :

Height = 2ft ; width = 1ft

a scale factor is a number used to reproduce a reduced dimension of a model by multiplying the actual dimeznsion or size of the model or object.

Since the height is of the scaled model is less than the actual height of the pyramid ; then it could be said that the scale factor is a fraction, because reduction has occurred.

(Height of scaled model / height of actual pyramid)

(2ft / 24ft) = 1/12

The  margin of error of the 8 simulations is 0.89z

The dataset is given as:

112 106 105 110 109 108 111 105

Using a graphing calculator, the standard deviation is:

σ =2.53

The  margin of error is then calculated using:

[tex]E = z * \frac{\sigma}{\sqrt n}[/tex]

Where z represents the critical value

So, we have:

[tex]E = z * \frac{2.53}{\sqrt 8}[/tex]

Evaluate

E = 0.89z

Answer:

The answer is A

Step-by-step explanation:

"The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9" is correct edg 2021

The correct statement is "The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9".

In rough terminologies, the limit from one side is when we only use one side of the function with respect to the considered point of interest (in input) to predict the value of the function at that point.

For a limit of a function f(x) to exist at a point a,

[tex]\lim_{x \to a^-} f(x) = \lim_{x \to a^+} f(x)[/tex]

That is, it has to approach (a) from both sides toward the same value, thus it cannot be oscillating.

From the table, looking at the value of slightly less than 9,

[tex]\lim_{x \to 9^-} f(x)= 4.73[/tex]

Looking at the value of slightly more than 9,

[tex]\lim_{x \to 9^+} f(x) = -4.73[/tex]

Since the lateral limits are different, the limit does not exist.

The correct statement is "The limit does not exist because the values of h(x) seem to oscillate between random values around x = 9".

Answer:

11 hrs 1 min (i think so based on math)

Step-by-step explanation:

If Johnna's reading rate is 150 words per min and there are 364 pages with about 275 words, you need to multiply 364 and 275 to get 100100 and divide that by 150 to get 667.3333333 round to the nearest tenth which will give you 667.3 and divide that by 60 because there are 60 minutes in an hour to get 11.12222222 and round that to the nearest tenth to get 11.1 which means it will take Johnna 11 hours and 1 minute to read the book.  I hope this is correct I'm really sorry if it isn't. :P

The picture demonstrates the greenhouse effect because all the grass within the rectangle is green. This is due to the fact that it received the nutrients it required. Carbon dioxide molecules provide the initial greenhouse heating needed to maintain water vapor concentrations. When carbon dioxide concentrations drop, Earth cools, some water vapor falls out of the atmosphere, and the greenhouse warming caused by water vapor drops.

Answer:

x = 10

Step-by-step explanation:

2+3+4+5+6 = 20

(20 + x) / 6 = 5

cross-multiply:

20 + x = 30

x = 10

Answer:

x = 10

Step-by-step explanation:

There are 6 numbers in total: 2, 3, 4, 5, 6, and whatever x is. In order for the average to be 5 in this scenario, all numbers must add up to 30, because 30/6 = 5.

2 + 3 + 4 + 5 + 6 = 20. 30-20=10. This means x would need to equal 10.
