Answer:

$239.02 and $10177

Step-by-step explanation:

Ann:

2868.32/6= 478.05

478.05/2= 239.02

Ann's sister:

3562.28/7= 508.89

508.89/5= 101.77

dont know if i did this right to be completely honest. but i feel like it's right. sorry if it's not.

Answer: (a) P(no A) = 0.935

              (b) P(A and B and C) = 0.0005

              (c) P(D or F) = 0.379

              (d) P(A or B) = 0.31

Step-by-step explanation: Pareto Chart demonstrates a relationship between two quantities, in a way that a relative change in one results in a change in the other.

The Pareto chart below shows the number of people and which category they qualified each public school.

(a) The probability of a person not giving an A is the difference between total probability (1) and probability of giving an A:

P(no A) = [tex]1-\frac{68}{1052}[/tex]

P(no A) = 1 - 0.065

P(no A) = 0.935

b) Probability of a grade better than D, is the product of the probabilities of an A, an B and an C:

P(A and B and C) = [tex](\frac{68}{1052})(\frac{258}{1052})(\frac{327}{1052})[/tex]

P(A and B and C) = [tex]\frac{5736888}{1164252608}[/tex]

P(A and B and C) = 0.0005

c) Probability of an D or an F is the sum of probabilities of an D and of an F:

P(D or F) = [tex]\frac{269}{1052} +\frac{130}{1052}[/tex]

P(D or F) = [tex]\frac{399}{1052}[/tex]

P(D or F) = 0.379

d) Probability of an A or B is also the sum of probabilities of an A and of an B:

P(A or B) = [tex]\frac{68}{1052} +\frac{258}{1052}[/tex]

P(A or B) = [tex]\frac{326}{1052}[/tex]

P(A or B) = 0.31

Answer:

The height of the rocket is greater than or equal to 1.039 feet during first 19.936 seconds.

Step-by-step explanation:

The height of the rocket launched from the ground is modelled after the following expression:

[tex]h(t) = -16.087\cdot t^{2}+320\cdot t +15[/tex] (1)

Where:

[tex]t[/tex] - Time, measured in seconds.

[tex]h[/tex] - Height, measured in feet.

After a careful reading to the statement, we translate all relevant information into the following mathematical inequation:

[tex]-16.087\cdot t^{2}+320\cdot t +15\ge 1.039[/tex] (2)

After some algebra, we get the equivalent inequation:

[tex]-(16.087\cdot t^{2}-320\cdot t -13.961)\ge 0[/tex]

[tex]16.087\cdot t^{2}-320\cdot t -13.961 \le 0[/tex]

[tex](x-19.936)\cdot (x+0.044)\le 0[/tex]

Which means that the following conditions must be observed to satisfy the inequation above:

[tex]x-19.936\le 0\,\land\,x+0.044\ge 0[/tex]

[tex]x\le 19.936\,s\,\land\,x\ge -0.044\,s[/tex]

[tex]0\,s\le x \le 19.936\,s[/tex]

The height of the rocket is greater than or equal to 1.039 feet during first 19.936 seconds.

Step-by-step explanation:

Answer:

[tex] f(-8) = -25 [/tex]

Step-by-step explanation:

[tex] f(x) = -x^2 - 3x + 15 [/tex]

[tex] f(-8) = -[(-8)^2] - 3(-8) + 15 [/tex]

[tex] f(-8) = -(64) + 24 + 15 [/tex]

[tex] f(-8) = -25 [/tex]

Generally speaking, arithmetic sequences have the form:

an=a1+(n-1)*d

Where:

an=the nth term in the sequence

a1=the 1st term in the sequence

n=the number of terms in the sequence

d=the difference between consecutive terms (i.e. d=an-an-1=a2-a1=a3-a2, etc.)

The SUM of the terms of an arithmetic sequence, notated Sn, is given by:

Sn=[n/2]*[2a1+(n-1)*d]

So if n=8 then:

a8=a1+7d=63

And if there are 94 terms in the sequence then:

S94=[94/2]*[2a1+93d]=47*(2a1+93d)=94a1+4371d=1000

So this is a system of equations where:

{ a1 + 7d = 63 (Multiply this first equation by -94 on both sides and add to second equation)

{ 94a1 + 4371d = 1000

-94a1 - 658d = -5922 (Add this new equation to second equation)

Therefore:

3713d = -4922

So:

d = -4922/3713

Answer: arithmetic / -30

Step-by-step explanation: This is an arithmetic sequence.

The reason I know that is because the same number is being

added each time to get the next term in the sequence.

In this case, we are adding -30 each time to reach the next term.

So the common difference is -30.

Step-by-step explanation:

Total sum of age of 12 students = 12*18 = 216;

Total sum of age of 8 students = 8*23 = 184;

Total sum of age of 20 students = 216+184 = 400;

Mean age of all the students = total age / number of students;

= 400/20 = 20 year

Answer:

Step-by-step explanation:

A living room wall is 13 feet long. If the perimeter of the rectangular living room is 56 feet long.

The formula for the perimeter of the rectangular living room =

P = 2(L + W)

P = 2L + 2W

L = Length = 13 feet

W = Width

P = 56 feet

56 = 2 × 13 + 2 W

56 = 42 + 2W

56 - 42 = 2W

14 = 2W

W = 14/2

W = 7

The width of the rectangular room is 7 feet long

A rectangular room would have 4 walls

Step-by-step explanation:

1+(2)(3)(4)

=1+(6)(4)

=1+24

=25

Hope this helps!

Answer: The answer would be 25

Step-by-step explanation: So the first thing you do, is multiply each number in parentheses first. So 2 mulitplied by 3 is 6. Then multiply 6 by 4 to get 25. Then add 1 to 24, to get 25. Hoped this helped

yes because when filling in the unknown (3*2-4=2) gets you the answer of 2.

Answer: Yes, it is a solution.

Step-by-step explanation:

3(2)=6-4=2

Answer:

When it yields a negative constant, the original function is everywhere concave down. In other words, when the second derivative of the equation of our parabola is positive, the parabola opens upward; when it is negative the parabola opens downward. Example 2: If y = -2(x-1)² + 3, determine the parabola's orientation.

Step-by-step explanation:

y=3

x=−3

Answer:

x=−1/10 y+ −27/10

x=−1/4 y+ −9/4

Step-by-step explanation:

−10x−y=27

Step 1: Add y to both sides.

−10x−y+y=27+y

−10x=y+27

Step 2: Divide both sides by -10.

−10x /−10= y+27 /−10

x=−1/10 y+ −27 /10

−4x−y=9

Step 1: Add y to both sides.

−4x−y+y=9+y

−4x=y+9

Step 2: Divide both sides by -4.

−4x /−4= y + 9/−4

x= −1/4 y + -9/4

No

Answer:

Jessica lived 10 months in Spain and 8 months in Colombia.

Step-by-step explanation:

Let x be the months Jessica spent in Spain, and y the months she spent in Colombia:

   1. x + y = 18

Using the information of words per month learned in each country, we can also write the equation:

    2. 160 * x + 200 * y = 3200

So now we have a system of two equations and two unknowns.

First we express y in terms of x, in the first equation:

We replace y in the second equation:

And solve for x:

Finally we use that value of x in the first equation and solve for y:

Jessica lived 10 months in Spain and 8 months in Colombia.
