P(odd) or P(multiple of 5)
When we roll 2 number cubes

all possible outcomes of their sum are 2,3,4,5,6,7,8,9,10,11,12.(11 possible outcomes)

Out of those possible outcomes
3,5,7,9,11 are odd (5 outcomes) and ...

5 and 10 are multiples of 5 (2 outcomes)

Now, P(odd) or P(multiple of 5) really means P(odd) + P (multiple of 5) =
(If we had “and” instead of “or” we multiply)
= (5/11) +(2/11)

5 x 20 is 100

3 x 20 is 60

100+60=160

Find the gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​
Luba_88 [7]

The gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​ is 15x²+6x-1.

<h3>What is the gradient?</h3>

A differential operator is used for a function having a vector value in three dimensions to produce a vector whose three components are the partial derivatives of the function with respect to its three variables.

The given equation for the curve is;

y = 5x³ + 3x² - x + 4​

The gradient of the tangent to the curve is;

\rm y'=\frac{dy}{dx} \\\\ y'= 5x^3 + 3x^2- x + 4 \\\\\ y'=15x^2+6x-1

Hence,the gradient of the tangent to the curve y = 5x³ + 3x² - x + 4​ is 15x²+6x-1.

To learn more about the gradient refer to;

Pani-rosa [81]

Answer:

The null hypothesis is not rejected  and hence Type II error occurred

Step-by-step explanation:

Here

The null hypothesis is as follows

H0 = Mean = 0.5

The alternate hypothesis is as follows -

H1 = Mean >0.5

For Type I error = The Null hypothesis is rejected if null hypothesis is actually true

Type II error =The Null hypothesis is not rejected when the null hypothesis is not true but is false.  

Here, the null hypothesis is not rejected  and hence Type II error occurred
