Order these numbers from least to greatest.
8.4051, 8.009, 8.4, 8.09
Answer:
8.009, 8.09, 8.4,8.4051
Step-by-step explanation
the 8.009 goes first because since it has zeros in it it would be the lowest than 8.09 is the next smallest 8.4 is the next big number because four is greater than zero and the biggest number because its has the bigger numbers in it.
Hope my explanation makes sense

=> w < 10-6
=> w < 4
so the answer is,
w < 4

What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
We have to given that;
In honors math increased by 12% in this year students.
Now, if S represents students.
Then, An expression to represent this situation is,
⇒ S + 12% of S
⇒ S + 0.12S
⇒ S (1 + 0.12)
⇒ 1.12S
Thus, The expression is true.

x = -7
m<GFD = 50°
m<CFD = 40°
Segment FD doesn't bisect <CFG because the angles aren't equal.
Step-by-step explanation:
<CFD and <GFD are complementary angles and their sum is 90°
-5x + 5 -7x + 1 = 90° add like terms
-12x + 6 = 90
-12x = 84 divide both sides by -12
x = -7
m<CFD is -5x + 5 ➡ (-5)×(-7) + 5 = 40°
m<GFD is -7x + 1 ➡ (-7)×(-7) + 1 = 50°

Suppose 49% of the population has a retirement account. If a random sample of size 896 is selected, what is the probability that the proportion of persons with a retirement account will differ from the population proportion by less than 3%?
Answer:
The probability is [tex]P( |\^ p - p | < 0.03 ) = 0.9275[/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is [tex]p = 0.49[/tex]
The sample size is n = 896
Generally the standard deviation of the sampling distribution is mathematically represented as
[tex]\sigma_{p} = \sqrt{ \frac{p(1 -p )}{n} }[/tex]
=> [tex]\sigma_{p} = \sqrt{ \frac{0.49(1 -0.49 )}{896} }[/tex]
=> [tex]\sigma_{p} = 0.0167[/tex]
Generally the the probability that the proportion of persons with a retirement account will differ from the population proportion by less than 3% is mathematically represented as
[tex]P( |\^ p - p | < 0.03 ) = P( \frac{ | \^ p - p|}{\sigma_p } < \frac{0.03}{0.0167} )[/tex]
[tex]\frac{|\^ p - p |}{\sigma_p } = |Z| (The \ standardized \ value\ of \ |\^p - p| )[/tex]
=> [tex]P( |\^ p - p | < 0.03 ) = P(|Z| < 1.796 )[/tex]
=> [tex]P( |\^ p - p | < 0.03 ) = P(- 1.796 < Z < 1.796 )[/tex]
=> [tex]P( |\^ p - p | < 0.03 ) = P(1.796 < Z) - P(Z < -1.796 )[/tex]
From the z table the area under the normal curve to the left corresponding to 1.796 and - 1.796 is
[tex]P(Z < -1.796 ) = 0.036247[/tex]
[tex]P(1.796 < Z) = 0.96375[/tex]
So
[tex]P( |\^ p - p | < 0.03 ) = 0.96375 - 0.036247[/tex]
=> [tex]P( |\^ p - p | < 0.03 ) = 0.9275[/tex]

In a certain card game, only the thirteen cards that are Hearts are used, and each player is dealt a hand of just two cards. How many ways are there to deal hands of two cards each to each of three players from a 13-card deck comprised of just the Hearts?
Solution :
It is given that only 13 cards that are Hearts that is used in a certain game.
And 2 hearts to each of the 3 players.
Therefore, the number of ways is
= [tex]$^{13} C_2 \times ^{11} C_2 \times ^{9} C_2$[/tex]
[tex]$= \frac{13 !}{11 ! \times 2!} \times \frac{11 !}{9 ! \times 2!} \times \frac{9 !}{7 ! \times 2!} $[/tex]
[tex]$=\frac{13 !}{7! \times 2! \times 2! \times 2!}$[/tex]
= 120 number of ways

What is an equation of the line that passes through the points (5,-2) and ( -5,0)?
Put your answer in fully reduced form.
9514 1404 393
Answer:
y = -1/5x -1
Step-by-step explanation:
When given 2 points, it can work well to start with the 2-point form of the equation for a line.
y = (y2 -y1)/(x2 -x1)(x -x1) +y1
y = (0 -(-2))/(-5 -5)(x -5) +(-2)
y = 2/(-10)(x -5) -2
y = -1/5x -1 . . . . . eliminate parentheses and collect terms
