What is -5x-5(8x)=0 solve for x

2 answers:

7 0

Multiply -5 and 8x to get -40x
then subtract 40x from -5x to get -45x
lastly divide 0 by -45 to get 0
x=0
hope this helps :)

-45(x) = 0 {Solve this}
Now, lets multiply (×) by both sides of the problem
45{x} = 0
Divide each of the sides of the problems by the number 45
So, this means that the value of x is probably going to be 0 ; x = 0

Plz help <br> decrease 420 by 7%

UNO [17]

So you would work out
5%= 21
and then you would need to work out 2%
1%=4.2
2%=8.4
21+8.4
=29.4
420-29.4
=390.6

What is the length of TH, when T (10,7), and H (-4,3)?

drek231 [11]

Answer:

TH=14.56

Step-by-step explanation:

Given: T(10,7) and H(-4,3)

Distance formula: $d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\text{Length of TH }=\sqrt{(-4-10)^2+(3-7)^2}$

$=\sqrt{14^2+4^2}$

$=\sqrt{196+16}$

$=\sqrt{212}$

$\approx 14.56$

Hence, The length of TH $\sqrt{212}\approx 14.56$

On a very hot summer day, 5% of the production employees at Midland States Steel are absent from work. The production employees

Ann [662]

Answer:

59.87% probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent

Step-by-step explanation:

For each employee, there are only two possible outcomes. Either they are absent, or they are not. The probability of an employee being absent is independent from other employees. So we use the binomial probability distribution to solve this question.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

In which $C_{n,x}$ is the number of different combinations of x objects from a set of n elements, given by the following formula.

$C_{n,x} = \frac{n!}{x!(n-x)!}$

And p is the probability of X happening.

5% of the production employees at Midland States Steel are absent from work.

This means that $p = 0.05$

What is the probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent

This is P(X = 0) when n = 10. So

$P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}$

$P(X = 0) = C_{10,0}.(0.05)^{0}.(0.95)^{10} = 0.5987$

59.87% probability of randomly selecting 10 production employees on a hot summer day and finding that none of them are absent
