Answer:

#7 = 430

#9 = 16

#11 = 930

Step-by-step explanation:

7 to the power of 2 is 49 /  49+3 is 52  /  52-9 is 43  / 43x10 is 430

66 divided by 11 is 5 /  5 +3 is 8   /   8 X2 is 16

18 -3 is 15  /  15 + 3 is 18 /  18 to the power of 2 is 324  /   324 - 14 is 310

310x3 is 930

lol, i was doing just fine on this hw until this. Pleeze help! solve for d+2 > 6. I am offering twenty-five Points
expeople1 [14]

Hello from MrBillDoesMath!

Answer:

d>4

Discussion:

I understand the question is asking us to solve for "d" in the inequality:

d + 2 > 6              => subtract 2 from both sides

d + 2 -2 > 6 - 2   => as 2 - 2 = 0

d > 6 -2 = 4


If I have misunderstood the question, please tell me.



Thank you,

MrB

MrRissso [65]

Answer:

A) sample mean = $1.36 million

B) standard deviation = $0.9189 million

C) confidence interval = ($1.93 million , $0.79 million)

*since the sample size is very small, the confidence interval is not valid.

Step-by-step explanation:

samples:

  1. $2.7 million
  2. $2.4 million
  3. $2.2 million
  4. $2 million
  5. $1.5 million
  6. $1.5 million
  7. $0.5 million
  8. $0.5 million
  9. $0.2 million
  10. $0.1 million

sample mean = $1.36 million

the standard deviation:

  • $2.7 million - $1.36 million = 1.34² = 1.7956
  • $2.4 million - $1.36 million = 1.04² = 1.0816
  • $2.2 million - $1.36 million = 0.84² = 0.7056
  • $2 million - $1.36 million = 0.64² = 0.4096
  • $1.5 million - $1.36 million = 0.14² = 0.0196
  • $1.5 million - $1.36 million = 0.14² = 0.0196
  • $0.5 million - $1.36 million = -0.86² = 0.7396
  • $0.5 million - $1.36 million = -0.86² = 0.7396
  • $0.2 million - $1.36 million = -1.16² = 1.3456
  • $0.1 million - $1.36 million = -1.26² = 1.5876
  • total $8.444 million / 10 = $0.8444 million

standard deviation = √0.8444 = 0.9189

95% confidence interval = mean +/- 1.96 standard deviations/√n:

$1.36 million + [(1.96 x $0.9189 million)/√10] = $1.36 million + $0.57 million = $1.93 million

$1.36 million - $0.57 million = $0.79 million

Simplify the expression 5 + 2 ⋅ {(2 + 5) ⋅ 5 + 5] <br><br> 1: 55 <br> 2: 85<br> 3: 105 <br> 4: 115
FromTheMoon [43]

Answer:

85

Step-by-step explanation:

Order of operations rules (PEMDAS) govern here.  Anything inside parentheses must be done first, followed by exponentiation, mult. and div., and add. and subtr. last.

Add 2+5 first:    5 + 2*{(7)*5 + 5}

Perform the work shown inside the brackets {  and  }:  5 + 2*{40}

Perform the indicated mult.:  5 + 80

Finally, add:  85

This hyperbola is centered at theorigin. Find its equation.Foci: (-2,0) and (2,0)Vertices: (-1,0) and (1,0)
beks73 [17]

SOLUTION

From the question, the center of the hyperbola is

\begin{gathered} (h,k),\text{ which is } \\ (0,0) \end{gathered}

a is the distance between the center to vertex, which is -1 or 1, and

c is the distance between the center to foci, which is -2 or 2.

b is given as

\begin{gathered} b^2=c^2-a^2 \\ b^2=2^2-1^2 \\ b=\sqrt[]{3} \end{gathered}

But equation of a hyperbola is given as

\frac{(x-h)^2}{a^2}-\frac{(y-k)^2}{b^2}=1

Substituting the values of a, b, h and k, we have

\begin{gathered} \frac{(x-0)^2}{1^2}-\frac{(y-0)^2}{\sqrt[]{3}^2}=1 \\ \frac{x^2}{1}-\frac{y^2}{3}=1 \end{gathered}

Hence the answer is

\frac{x^2}{1}-\frac{y^2}{3}=1
