Could someone tell me how to work this problem 7.86 x4.6 please

1 answer:

5 0

In order to solve this problem, we just have to multiply it normally. Firstly, remove the decimals first and proceed with the multiplication process.
786 x 46 would be 36156. Going back to the decimals, how many decimal places are there in total? So there are three decimal places. Now, from 6, count 3 backwards, and that makes 36.156. I hope that this answer helps. Let me know if you need more help next time.

Associative property of (21)(7)(3x) ? PLEASE HELPPPP 40 PTS!!!!

sdas [7]

Ehh, now it's letting me answer.

So the associative property is basically as long as it's addition or multiplication, you can move around the groupings and it will still be the same.

For example, you can say:(21 * 7) (3x) instead of (21)(7)(3x)

And it would be equal to the old version.

(To answer your other question, the commutative property is you can move around all the parts of the equation as long as it's addition or multiplication.)

So basically, it would be the first one you sent me.

Answer:

(a) The value of x is 0.30.

(b) The probability that a reported case of rabies is not a raccoon is 0.45.

Step-by-step explanation:

Denote the events as follows:

R = reported case of rabies is a raccoon

F = reported case of rabies is a fox

B = reported case of rabies is a bat

O = reported case of rabies is a some other animal.

The data provided is:

P (R) = 0.55

P (F) = 0.11

P (B) = 0.04

P (O) = x.

(a)

A property of a probability distribution is that the sum of all individual properties is 1.

That is, $\sum P(X)=1$

Compute the value of x as follows:

$\sum P(X)=1\\P(R)+P(F)+P(B)+P(O)=1\\0.55+0.11+0.04+x=1\\0.70+x=1\\x=1-0.70\\x=0.30$

Thus, the value of x is 0.30.

(b)

The probability of the complement of an event is the probability of its not happening.

$P(A^{c})=1-P(A)$

Compute the probability that a reported case of rabies is not a raccoon as follows:

$P(R^{c})=1-P(R)\\=1-0.55\\=0.45$

Thus, the probability that a reported case of rabies is not a raccoon is 0.45.

(c)

Compute the probability that a reported case of rabies is either a bat or a fox as follows:

$P(B\cup F)=P(B)+P(F)\\=0.11+0.04\\=0.15$

Thus, the probability that a reported case of rabies is either a bat or a fox is 0.15.

Anna paid $4 for renting a video game for 4 days. Which graph shows the relationship between the costs of renting a video game f

Andreas93 [3]

She paid $ 4 for renting a video game for 4 days...that means she paid $ 1 per day.

A horizontal axis is labeled days, a vertical axis is labeled cost of rental.
(x,y)...x is gonna be ur days and y is gonna be ur cost of rental

ur equation is gonna be y = x

points are plotted (1,1) , (2,2), (3,3)

^^ this is the graph u use ...graph B
