Malik and Mia both converted to a decimal. Malik says
the answer is 0.45 and Mia says the answer is 0.45. Which
answer is correct? Explain why that is the correct answer, and
the other is incorrect.

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.

Answer:

25

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

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

Step-by-step explanation:

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.

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.

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:

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:

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.

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
