How to solve: -8 + square root of (5a-5) = -3

Mathematics
1 answer:
Lorico [155]3 years ago
5 0

Answer:

a=6

Step-by-step explanation:

-8+\sqrt{(5a-5)}=-3

Adding 8 both sides.

8-8+\sqrt{(5a-5)}=-3+8

\sqrt{(5a-5)}=5

Squaring both sides.

(\sqrt{(5a-5)})^2=5^2

5a-5=25

Adding 5 both side.

5a-5+5=25+5

5a=30

Dividing by 5 both sides.

\frac{5a}{5}=\frac{30}{5}

∴ a=6

The warranty for a particular system on a new car is 2 years. During which there is no limit to the number of warranty claims pe
const2013 [10]

Answer: by using Poisson distribution

The warranty for a particular system on a new car is 2 years

P(x=2)= 0.143

There is no limit to the number of warranty claims per car

P(X=0) = 0.449

Step-by-step explanation:

<u>step:-1</u>

A random variable X is said to follow a Poisson distribution if it assumes only non-negative values and its probability distribution is given by

P(X=x) = \frac{e^{-w}w^{x}  }{x!}

here w>0 is called the parameter of the distribution

<u>Step 2</u>:- Given mean value of Poisson distribution = 0.8

The warranty for a particular system a new car is 2 years

P(X=x)=P(X=2)=\frac{e^{-0.8}{0.8^{2} }  }{2!}

P(x=2)= 0.143

<u>Step 3</u>:-

Given mean value of Poisson distribution = 0.8

There is no limit to the number of warranty claims per car

P(X=x)=P(X=0)=\frac{e^{-0.8}{0.8^{0} }  }{0!}

P(X=0) = 0.449

Find the value of this pronumeral
patriot [66]
A straight angle measures 180º. 
A triangle's interior angles also measure 180º.  
The angle measuring 130º is complementary to the corresponding interior angle, so that interior angle plus 130 has to equal exactly 180º. 
180 - 130 = 50º 
45 + 50 = 95º, so subtract that from 180 to find the measure of the last interior angle of the triangle. 
180 - 95 = 85º 
That angle of 85º is complementary to the other outside angle, n, and to find that subtract 85 from 180. 
180 - 85 = 95º 
n = 95 
Hope this helps!
