Answer:

1/2

Step-by-step explanation:

the probability of the die rolling an even number = the probability of the die rolling an odd number =1/2

Let us name these 2 dice as A and B

One die can roll an even and the other can roll an odd, in the following cases

A rolls even and B rolls odd. The probability of this happening =1/2×1/2

A rolls odd and B rolls even. The probability of this happening =1/2×1/2

∴ The required probability

=1/2×1/2+1/2×1/2

=1/4+1/4

=1/2

Answer:

The linear regression model that will determine approximate Fat Grams (y) as a function of Calories (x) is given by

y = 0.054 x - 2.105

Hence the correct option is B.)

Step-by-step explanation:

Step 1: Find X⋅Y and as it was done in the table below.

Step 2: Find the sum of every column:

ΣX = 1560, ΣY = 67, ΣX.Y = 14860 , ∑( $\textbf{X}^{2}$ ) = 337600

Step 3: Use the following equations to find a and b:

a = = -2.105

b = $\frac{n.\sum{XY} - \sum{X}.\sum{Y}}{n.\sum{(X^{2})}- (\sum{X})^{2} }$ = 0.054

Step 4: Substitute a and b in regression equation formula

y = a + b⋅x= −2.105 + 0.054⋅x

The linear regression model that will determine approximate Fat Grams (y) as a function of Calories (x) is given by

y = 0.054 x - 2.105

Hence the correct option is B.)

Andrea multiplied 6.75 x 10^6 and 0.2 x 10^6 and got 6.95 x 10^6. explain Andrea’s mistake and give the correct answer

Dvinal [7]

Answer:

Correct answer = $1.35\times10^{12}$

Step-by-step explanation:

Given:

Andrea multiplied 6.75 x 10^6 and 0.2 x 10^6 and got 6.95 x 10^6.

Question asked:

Explain Andrea’s mistake and give the correct answer.

Solution:

The above question is of exponential question:

Here Andrea simply added 6.75 to 0.2 and got 6.95 and took 10^6 as common and written down wholly 6.95 x 10^6 which is incorrect.

Here we multiply 6.75 to 0.2 and get 1.35 and secondly to multiply 10^6 with 10^6 we have to understand the rule of exponents:-

As we know:

$a^{m} \times a^{n} =a^{m+n}$

$Similarly,\ 10^{6} \times 10^{6}=10^{6+6}=10^{12}$

Hence when we multiplied 6.75 x 10^6 and 0.2 x 10^6 originally we got $1.35\times10^{12}$
