Answer:

Yes, they differ across the two delivery styles of the previous course.

Step-by-step explanation:

So, we are given the following data or information or parameters from the question above;

Flipped(group) => 166(n) 2.45(l) 1.09(s).

Traditional(group) => 129(n) 1.59(l) 1.20(s).

Therefore, the hypothesis is given below as; Jo : b1 = b2, Jx : b1 ≠ b2.

Recall that we are given; 166 = (n1), 2.45 = (l1), 1.09 = (s1) and 129 = (n2) , 1.59 = (l2), 1.20 = (s2).

Therefore, we will be using the following mathematical representation or formula to solve this question;

s = √(s1^2/ n1 + s2^2/n2).

When we slot it the values accordingly and solve for s, we will have a value of;

s = 0.1354.

Thus , for our t*, we can calculate that by using the formula below:

t*= l1 - l2/ s.= (2.45 - 1.59)/ 0.1354= 6.35.

Thus: p value = 2P(V> 6.35) = 2.1 × 10^-10.

Since we are given that a=0.01, thus, p value is less than 0.01 we can reject Jo.

And we got:

[tex] 280 x10^4[/tex]

And if we move the decimal point two units to the left we got:

[tex] 2.8 x10^6[/tex]

Step-by-step explanation:

We know that each elefeant weight about [tex]1.4 x10^4[/tex]

And we have a total of 200 elephants so then we can find the total weights for the elephants with this formula:

[tex] 200 *1.4*10^4[/tex]

Using the properties of multiplication we can do this:

[tex] (200*1.4) *10^4[/tex]

And we got:

[tex] 280 x10^4[/tex]

And if we move the decimal point two units to the left we got:

Answer:

1000m

STEP BY STEP EXPLANATION: 300m+300m+200m+200m

=600m+400m

=1000m

The perimeter of the field is 1000m

Since the field is 300m long and 200m wide.

We know that the perimeter of the rectangle is

= 2(length + width)

= 2(300 + 200)

= 2(500)

= 1000m

Therefore we can conclude that The perimeter of the field is 1000m

Answer:

The equation of the parabola is y=(1/8)x^2

[tex]y=\dfrac{1}{8}x^2[/tex]

Step-by-step explanation:

We know the vertex (0,0) and the focus (0,2) of the parabola.

The equation in vertex form is written as:

[tex]y=a(x-h)^2+k\\\\\text{vertex}=(h,k)[/tex]

Then, in this case, we have the equation:

[tex]y=a(x-0)^2+0=ax^2[/tex]

As the focus is (0,2), it is at a distance of 2 units from the vertex (0,0).

For the focus, we have the following equation:

[tex]4p(y-k)=(x-h)^2[/tex]

where p is the distance from the focus to the vertex (in this case, p=2).

h and k are the vertex coordinates, both 0.

So we have:

[tex]4p(y-k)=(x-h)^2\\\\4(2)(y-0)=(x-0)^2\\\\8y=x^2\\\\y=\dfrac{1}{8}x^2[/tex]

Answer:

[tex]y = 4(x^{2} + 8x + 15) = 4x^{2} + 32x + 60[/tex]

Step-by-step explanation:

A parabola has the following format:

[tex]y = f(x) = ax^{2} + bx + c[/tex]

If a is positive, it's minium value is:

[tex]y_{M} = -\frac{\bigtriangleup}{4a}[/tex]

In which

[tex]\bigtriangleup = b^{2} - 4ac[/tex]

Factoring:

[tex]ax^{2} + bx + c = a(x - x_{1})*(x - x_{2})[/tex], in which [tex]x_{1} and x_{2}[/tex] are the intercepts.

In this question:

[tex]x_{1} = -5, x_{2} = -3[/tex]

So

[tex]a(x - x_{1})*(x - x_{2}) = a*(x - (-5))*(x - (-3)) = a*(x+5)*(x+3) = a*(x^{2} + 8x + 15)[/tex]

Suppose a = 1, we have:

[tex]x^{2} + 8x + 15[/tex]

[tex]\bigtriangleup = 8^{2} - 4*1*15 = 4[/tex]

The minimum value will be:

[tex]y_{M} = -\frac{4}{4} = -1[/tex]

We want this minimum value to be -4, which is 4 times the current minimum value, so we need to multiply a by 4. Then

[tex]a = 4[/tex]

And the parabola is:

[tex]y = 4(x^{2} + 8x + 15) = 4x^{2} + 32x + 60[/tex]

Answer:

n = 3/5

Step-by-step explanation:

We are given the ratio 6 : 10.

We see that we want to get a number n to 1 ratio; n : 1

In order to get one, we must divide 10 by 10, and so we would divide the entire ratio by 10 and simplify:

6/10 : 10/10

3/5 : 1 or 0.6 : 1

Answer:

C. The price of "personal computers and peripheral equipment" decreased 89.3%.

Step-by-step explanation:

Consumer Price Index (CPI) measures change in price level, of weighted average market basket of consumer goods & services produced by households.

CPI calculated change in current year price level with regards to base year price level, base year price = 100. CPI > 100 implies that inflation (price rise) has occurred in current year from base year. CPI < 100 implies that deflation (price fall) has occurred in current year from base year.

CPI for 'personal computers & equipment' = 10.7 implies that prices of 'personal computers & equipment' have fallen or deflated. As per base year price = 100, prices have fallen by 100 - 10.7 = 89.3%

Answer:

The answer is "Option B"

Step-by-step explanation:

[tex]CPI = 10.7 \ in \ (\ june, \ 2006) \\\\CPI_{2006}= \frac{\ cost \ of \ basket \ of \ year \ 2006}{\ cost \ of \ basket \ of \ year \ 1982 \ to \ 84} \times 100\\\\\frac{10.7}{100} =\frac{\ cost \ of \ basket \ of \ year \ 2006}{\ cost \ of \ basket \ of \ year \ 1982 \ to \ 84}\\\\[/tex]

The cost of basket [tex]_{1982 \ to 1984} \times 0.107= \ cost \ of \ basket_{2006} \\\\[/tex]

[tex]\ cost \ of \ basket_{1982 \ to 1984} \ is \ given \ as \ 100\\\therefore \ \ cost \ of \ basket_{2006} = 100 \times 0.107\\\\[/tex]

                                  [tex]\ = 10.7\\\\[/tex]

Step 1:  Answer part a

He has 3.5 pounds of clay and each bowl is 0.5 pounds of clay.  Therefore, 3.5 / 0.5 will give us the amount of bowls he can make.  

3.5 / 0.5

7

Answer: He can make 7 bowls

Step 2:  Answer part b

I don't really understand what the questions asking about how much clay does he need to make with all of his clay.  If you explain what that means I can answer it.

If you meant how much mugs he is able to make → 14

If you meant how much clay he needs to have for each mug → 0.25

Answer & Explanation:

Part A

It gives us 2 numbers to determined how much bowls he can make.

He need 0.5 of clay to make 1 bowl and he has 3.5 pounds of clay.

[tex]3.5[/tex] ÷ [tex]0.5[/tex]

= [tex]7[/tex]

He can make 7 bowls out of the 3.5 pounds of clay that he has.

Part B

This question is very confusing...

He can make 1 mug with 0.25 pounds of clay.

[tex]3.5[/tex] ÷ [tex]0.25[/tex]

= [tex]14[/tex]

He can make 14 mugs if he uses all of his clay.

Answer:

  B.  129.7°

Step-by-step explanation:

The law of sines tells you ...

  sin(C)/c = sin(A)/a

  sin(C) = (c/a)sin(A)

  C = arcsin((c/a)sin(A)) = arcsin(117/57·sin(22°)) = 50.3°

The value shown is the result of using the arcsin function, but we know that the supplement of this angle has the same sine value. Then, we could have ...

  C = 180° -50.3° = 129.7°

The figure shows C as an obtuse angle, so we choose this latter value as the appropriate answer to this question.

  C = 129.7° . . . . . matches choice B

_____

Comment on the answer

We note that choice C (50.3°) matches the result of straightforward use of the law of sines. This triangle actually has two solutions for angle C, as we have noted above. Often, figures are "not to scale," so the appearance of angle C as an obtuse angle cannot always be taken at face value. Here, because both choices for angle C are offered, we use the appearance of the figure to help decide the right one.

Answer:

Volume of the pyramid =  927.72 m² (Approx)

Answer:

21

Step-by-step explanation:

Answer:

As shown in picture, if MC is median of triangle ABC, M is midpoint of AB.

Denote the coordinate of A, B and M are (Ax, Ay), (Bx, By) and (Mx, My) respectively.

The formula relating coordinate of A, B and M is:

Ax + Bx = 2Mx

Ay + By = 2My

In detail,

-1 + Bx = 2 x 4 => -1 + Bx = 8 => Bx = 9

11 + By = 2 x 11 = > 11 + By = 22 => By = 11

=> Option D is correct
