The 4th option is the correct answer.

Explanation:

Here we will place the opposite of the number of the divisor in the top left box. Now we will bring down the coefficient of the squared term or 2. Now, we will multiply the number in the top left box or 5 with the times of the coefficient of the squared term. This gives 10 and we will place 10 in the second column. This column now contains -1 and 10 and adding these we get 9. Now we will multiply 5 with the result of the second column or 9 to get 45, We will place 45 in the third column which already has 4, and adding both we get 49.

I need some help with this calculus question

Over [174]

The tangent to $y$ at the point (0, 5) has a slope equal to the derivative evaluated at $x=0$ .

$y=x^4+5e^x\implies y'=4x^3+5e^x\implies y'(0)=5$

This tangent passes through the point (0, 5), so its equation is

$y-5=5(x-0)\implies y=5x+5$

The normal line passes through the same point, but is perpendicular to the tangent line, so its slope is the negative reciprocal of the slope of the tangent. So the equation for the normal line is

$y-5=-\dfrac15(x-0)\implies y=5-\dfrac x5$

Given that events A and B are independent with P(A)=0.3P(A)=0.3 and P(A\cap B)=0.27P(A∩B)=0.27, determine the value of P(B)P(B),

Stolb23 [73]

Answer:

0.9

Step-by-step explanation:

Since A and B are independent hence;

P(A∩B) = P(A)P(B)

Given the following

P(A∩B) = 0.27

P(A) = 0.3

Required

P(B)

Substitute into the formula;

P(B) = P(A∩B)/P(A)

P(B) = 0.27/0.3

P(B) = 0.9

Hence the value of P(B) is 0.9
