Answer:

I think it is tho

let's wait for another answer

Answer:

x = 1

Step-by-step explanation:

From ΔABC and ΔDEF,

m∠C = m∠F [Given]

AC = DF [Given]

BC = EF [Given]

Therefore, ΔABC ≅ ΔDEF [By SAS property of congruence]

AB = DE [CPCTC]

2x - 1 = 5x - 4

5x - 2x = 4 - 1

3x = 3

x = 1

36 dollars per person and they all will pay 2 dollars each the large group will hit a wall

Answer:

35 times, or D

Step-by-step explanation:

A bag contains 5 red marbles, 6 blue marbles, 3 green marbles, 4 black marbles, and 2 yellow marbles. A marble will be drawn from the bag and replaced 100 times. What is a reasonable prediction for the number of times a green or black marble will be drawn?

A quick lesson on probability:

The probability of an event is: (the number of ways what you want can happen) / (total number of outcomes possible). For example, in a coin flip, there is 1 way to get heads, and 2 possible outcomes. Thus, the possiblity  of flipping a coin and getting heads is:

(1 way to get heads) / (2 possible outcomes) = 1/2

Then, if we were to flip the coin 100 times, we would expect about 1/2 of the times to be heads, so we should expect heads 50 times.  

On to the problem.

There are 3 green marbles and 4 black marbles, so there are 7 ways to draw a green or black marble.

Then, there are 5 + 6 + 3 + 4 + 2 = 20 possible outcomes.

Using the formula to find the probability, substitute the values we just found.

(the number of ways what you want can happen) / (total number of outcomes possible) =

(7 ways to draw a green or black marble) / (20 marbles that can be drawn) = 7/20 chance of getting a green or black marble.

Then, because there is a 7/20 chance of getting what we want, and there are 100 draws, we can say that an we should get green or black

7/20 * 100 = 35 times, or D

Step-by-step explanation:

[tex]-\frac{60}{6}a + \frac{84}{8} + \frac{1}{4}a - \frac{1}{10}[/tex]

= [tex]-\frac{120}{12}a + \frac{3}{12}a + \frac{420}{40} - \frac{4}{40}[/tex]

Answer: The 3rd one.

Step-by-step explanation:

Answer:

Length DE= 2√2

Length EF= 2√2

Step-by-step explanation:

The 45-45-90 rule is very special but this question is really simple. You have all the angles and one side.

STEPS:

1) Take 45 from angle D and use its sine to find side EF

2) sin45= x/4 => 2.82 or  2√2

3) Take either cos45 from angle D or use Pythagoras since we now have enough side lengths to use Pythagoras (faster for me to use cosine).

4) cos45=x/4 => 2.82 or  2√2

Further explanation:

If you don't understand the sine and cosines, here's a word play to help.

S O/H

C A/H

T O/A

S=Sine

C=Cosine

T= Tangent

O= Opposite

H= Hypotenuse

A= Adjacent

Answer:

44 because 50% of 88 is 44

Step-by-step explanation:

88 / 100 * 50

0.88 * 50

44

or in this case when it is 50% just do:

88 / 2

Answer:

0.136

Step-by-step explanation:

If you have a calculator with statistical functions, this problem is straightforward.

Use the normcdf function as follows:

normcdf(300,350,400,50) = 0.136

This result is the probability that a worker makes between $300 and $350 per week:  0.136

The comparison of the given function and the graph is required.

It is true that y-intercept of both functions is 0.

It is false that the slope of both functions is [tex]\dfrac{3}{2}[/tex]

It is true that the graphs function has a greater rate of change.

It is true that point (0,0) is the point of intersection for both the functions.

Two points of the graph are (0,0),(-2,-3).

The equation of the line is

[tex]y-0=\dfrac{-3}{-2}(x-0)\\\Rightarrow y=\dfrac{3}{2}x[/tex]

The other equation is [tex]y=\dfrac{2}{3}x[/tex]

Both the lines pass through the origin so the y intercept of both the functions is 0.

Only the slope of the function in the graph is [tex]\dfrac{3}{2}[/tex] the other function has slope [tex]\dfrac{2}{3}[/tex]

Writing the decimal forms of the slopes [tex]\dfrac{3}{2}=1.5[/tex] and [tex]\dfrac{2}{3}=0.67[/tex]

The function in the graph does have a greater rate of change.
