Answer:

<h2> ${7}^{3} (as \: a \: single \: power \: of \: 7)$ </h2>

Step-by-step explanation:

Given 

${7}^{4} \div 7$

Since,

${a}^{x} \div {a}^{y} = {a}^{x - y}$

Hence,

$= {7}^{4 - 3}$

$= {7}^{3} (ans)(as \: a \: single \: power \: of \: 7)$

There are eight students in a class. Only one of them has passed Exam P/1 and only one of them has passed Exam FM/2. No student

Svetach [21]

Answer: There is probability of 0.57 chances that exactly three students from a group of four students have not passed Exam P/1 or Exam FM/2.

Step-by-step explanation:

Total number of students = 8

Number of student who has passed Exam P/1 = 1

Number of student who has passed Exam FM/2 = 1

No student has passed more than one exam.

According to question, exactly three students from a randomly chose group of four students have not passed Exam P/1 or Exam FM/2.

So, Probability will be

$\frac{^6C_3\times ^2C_1}{^8C_4}\\\\=\frac{20\times 2}{70}\\\\=\frac{4}{7}\\\\=0.57$

Hence, there is probability of 0.57 chances that exactly three students from a group of four students have not passed Exam P/1 or Exam FM/2.

(-7)-(-44)/22+((-4)*59) with calculation

Pavel [41]

Hi,

$\frac{ ( - 7) - ( - 44)}{22 + (( - 4) \times 59)}$

$\frac{ - 7 - ( - 44)}{22 + (( - 4) \times 59}$

$\frac{ - 7 + 44}{22 + (( - 4) \times 59}$

$\frac{ - 7 + 44}{22 + ( - 236)}$

$\frac{37}{22 + ( - 236)}$

$\frac{37}{22 - 236}$

$\frac{37}{ - 214}$

good look :)

Hello,

In my old memories,
p(μ-2σ<=X<=μ+2σ)=95%
p(μ-3σ<=X<=μ+3σ)=99%

1000-2*200=1000-400=600
1000+2*200=1000+400=1400
