Between-group design compares two groups (randomly formed) on the same task, such as movement speed.

Given things that there are two groups that are randomly formed for the same task.

A between-group design in experimental design is an experiment in which two or more groups of individuals are assessed simultaneously by separate testing factors. This design is typically used instead of, or in conjunction with, the within-subject design, which applies identical modifications of circumstances to each participant in order to monitor the reactions.

F(x) = x ^ 2 - 8x + 7

bekas [8.4K]

Answer:
They have the same x-value
f(x) has the greater minimum
Step-by-step explanation:
To find the vertex of a second degree equation, in this case the minimum value, we can use the following equation:
x = -b / 2a
Remember that a second degree equation has the following form:
ax^2 + bx + c
so a = 1, b = -8 and c = 7. Now you have to substitute in the previous equation
x = - (-8) / 2(1)
x = 8 / 2
x = 4
This means that the two functions have the same x-value.
The y value of f(x) would be
f(4) = (4)^2 - 8(4) + 7
f(4) = 16 - 32 + 7
f(4) = -9
So the vertex, or minimun value of f(x) would be at the point (4, -9).
The vertex, or minimun value of g(x) is at the point (4, -4).
So f(x) has a minimum value of -9 and g(x) a minimum value of -4.

One thousand tonnes (1000 t, one t equals 10 cubed kg) of sand contains about a trillion (10 super 12) grains of sand. How many

Phantasy [73]

Answer with Step-by-step explanation:

Since 1 mole of sand will contain Avagadro's Number of sand particles (by definition of 1 mole)

Thus we have

1 mole of sand = $6.022\times 10^{23}$ sand particles

Thus in number of trillion sand particles we have no of trillion sand particles in 12 mole is

$\frac{6.022\times 10^{23}}{10^{12}}=6.022\times 10^{11}$

Now since it is given that mass of 1 trillion sand particles is 1000 tonnes Thus the mass of $6.022\times 10^{11}$ trillion sand particles is

$Mass=1000\times 6.022\times 10^{11}=6.022\times 10^{14}tonnes$

Part 2)

Since it is given that volume of 1 sand particle is $1.0mm^{3}$ thus the volume of 1 mole of sand is volume of $6.022\times 10^{23}$ sand particles

Thus volume of 1 mole is $V=1.00\times 10^{-18}km^{3}\times 6.022\times 10^{23}=6.022\times 10^{5}km^{3}$

Now since the Area of united states is $A=3.6\times 10^{6}mile^{2}=5.8\times 10^{6}km^{2}$

Thus the depth of the sand pile is

$Depth=\frac{Volume}{Area}=\frac{6.022\times 10^5}{5.8\times 10^6}=0.10387km=103.8meters$

an initial deposit of $200 is made into an account that pays 4.2% annual interest. What is a model to represent the balance in t

Sholpan [36]

You would use the equation y = A(1+r)^t

A = Original amount = 200
r = interest rate = 0.042 (when converted from percent to decimal)
t = time = x

Plug them in and you get the model: y = 200(1+0.042)^x

or just simplify the parentheses to (1.042)

A basketball team scored 105 points during one game. There were as many two-point baskets as free throws (1 point each), and the

liubo4ka [24]

The number of three-point baskets from the substitution method is 15.

According to the statement

we have given that the total score of basket ball is 105 points and there were as many two-point baskets as free throws (1 point each), and the number of three-point baskets was five less than the number of free throws.

And we have to find the number of three-point baskets.

So, For this purpose, we know that the

Final Score S = 105

Two point baskets T = Free throws F -(1)

Three point baskets H = F - 5 -(2)

Now, we know that the

The final score is equal to 3 times the number of three point baskets plus 2 times the number of two point baskets plus 1 times the number of free throws

So,

S = (3*H) + (2*T) + (1*F)

Here we can use substitution method,

Now we can substitute

105 = 3H + 2T + 1F

105 = 3H + 2F + 1F {substitute from equation (1)}

105 = 3(F-5} + 2F + 1F {substitute from equation (2)}

105 = 3F -15 + 2F + 1F

105 = 6F - 15

120 = 6F

F =20

Now that we get the value of F, now we can substitute into Eqn 2 to find H

H = F -5

H = 20 - 5

H = 15

So, The number of three-point baskets from the substitution method is 15.
