The relative frequencies missing in the table are :

ham-wheat = 0.231, cheese-wheat = 0.0.462.

rye-turkey = 0.167, rye-ham = 0.417.

<u> Step-by-step explanation: </u>

From the given data we have to count the frequencies of wheat and rye chosen to find the missing values.

The frequency of wheat chosen = 13.

The frequency of rye chosen = 12.

Relative Frequency can be obtained by dividing the combined frequency by the total number of data values.

Wheat combinations:

1) The frequency of ham-wheat = 3.

Then the relative frequency of ham-wheat = $\frac{3}{13}$ .

The the relative frequency of ham-wheat = 0.230769 or 0.231.

2) The frequency of cheese-wheat = 6.

Then the relative frequency of cheese-wheat = $\frac{6}{13}$ .

The the relative frequency of cheese-wheat = 0.4615 or 0.0.462.

Rye combinations:

1) The frequency of rye-turkey = 2.

Then the relative frequency of rye-turkey = $\frac{2}{12}$ .

The the relative frequency of rye-turkey = 0.1666 or 0.167.

2) The frequency of rye-ham = 5.

Then the relative frequency of rye-ham = $\frac{5}{12}$ .

The the relative frequency of rye-ham = 0.41667 or 0.417.

What is the product?<br><br> (5.63 x 10^5) x 5,600,000

victus00 [196]

Answer: $3.1528 \times 10^{12}.$

Step-by-step explanation: Given expression $(5.63 \times 10^5) \times 5,600,000$ .

In order to find the product of given expression, we need to convert 5,600,000 into scientific notation, because other number is also in scientific notation.

5,600,000 = 5.6 × 10^6.

Therefore, $(5.63 \times 10^5) \times 5,600,000 =(5.63 \times 10^5) \times (5.6 \times 10^6)$ .

Now, multiplying 5.63 × 5.6 first, we get 31.528.

And 10^5 × 10^6 = 10^11.

Therefore,

$(5.63 \times 10^5) \times (5.6 \times 10^6) = 31.528 \times 10^11$ .

Triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 t

faust18 [17]

Answer:

Answer: The correct option is (D) P″(9, -12) and Q″(15, -3).

Step-by-step explanation: Given that triangle PQR is dilated by a scale factor of 1.5 to form triangle P′Q′R′. This triangle is then dilated by a scale factor of 2 to form triangle P″Q″R″.

The co-ordinates of vertices P and Q are (3, -4) and (5, -1) respectively.

We are to find the co-ordinates of the vertices P″ and Q″.

Case I : ΔPQR dilated to ΔP'Q'R'

The co-ordinates of P' and Q' are given by

Case II : ΔP'Q'R' dilated to ΔP''Q''R''

The co-ordinates of P'' and Q'' are given by

Thus, the co-ordinates of the vertices P'' and Q'' are (9, -12) and (15, -3).

Option (D) is CORRECT.

Step-by-step explanation:

Evaluate the difference quotient?

goldenfox [79]

F(x) = x^2 + 4x - 5

[f(a + h) - f(a)] / h

f(a) = a^2 + 4a - 5
f(a + h) = (a + h)^2 +4(a + h) - 5
   = a^2 + 2ah + h^2 + 4a + 4h - 5

f(a + h) - f(a) = a^2 + 2ah + h^2 + 4a + 4h - 5 - ( a^2 + 4a - 5)
---------------- ------------------------------------------------------------
   h h

   = 2ah + h^2 + 4h h (2a + h + 4) 2a + h + 4
   ------------------- = ------------------- =
   h h
