Answer:

( x − 4 ) ( x − 8 ) is the factorised form of the expression.

Step-by-step explanation:

−

We can Split the Middle Term of this expression to factorise it.

In this technique, if we have to factorise an expression like

, we need to think of 2 numbers such that:

For each day in New England, the probability that it is mostly cloudy is 0.10 . Cindi is planning to go leaf watching, and her f

kolbaska11 [484]

Answer:

0,37

Step-by-step explanation:

It will be easier if we noun the events.

A= Cindi's friend comes to England.

B= New England is mostly cloudly.

We are searching the probability of just A doesn´t happen or just A happens but not B.

The probability of A doesn´t happen is one minus the probability of A:

$=(A^{|} )=1-P(A)=1-0.7=0.3$

The events A and B are independent for this reason the probability than both occurs is the product of the probability of each event. It means:

$P(A \cap B)= P(A)P(B)=0.1*0.7=0.07$

The probability of A doesn´t happen or A and B happen is:

$P(A^{|} \cup (A \cap B))= P(A^{|} )+P (A \cap B)-P(A^{|} \cap A\cap B)=0.3+0.07-0=0.37$

Conclusively we have to rest the probability of A doesn´t happen and A and B happen, but A happens and doesn´t happen and the same time is impossible. For this reason, we have the same result.

$P(A^{|} \cup (A \cap B))-P(A^{|} \cap A\cap B)=0.37-0=0.38$

Then the probability either Cindi's friend does not come to New England, or she does come but it is mostly cloudy is 0.37

a storage drum in the shape of a cylinder is 3 feet tall and has a diameter of 4 feet. what is the total surface area of the sto

nlexa [21]

Answer:

$SA=62.8\ ft^2$

Step-by-step explanation:

we know that

The surface area of a cylinder is equal to

$SA=2\pi r^{2}+2\pi rh$

we have

$h=3\ ft$

$r=4/2=2\ ft$ ----> the radius is half the diameter

assume

$\pi =3.14$

substitute

$SA=2(3.14)(2)^{2}+2(3.14)(2)(3)$

$SA=62.8\ ft^2$
