Answer:

The value of the equation is  a= \frac{2}{5} or 0.4

Step-by-step explanation:

Consider the provided equation.

We need to solve the equation for a.

1.7a + 0.3a = \frac{4}{5}

Add the like terms.

2a= \frac{4}{5}

Now divide both sides by 2.

\frac{2a}{2}= \frac{4}{5\times 2}

a= \frac{2}{5} or a= 0.4

Hence, the value of the equation is a= \frac{2}{5} or 0.4

Assume the readings on thermometers are normally distributed with a mean of 0degreesC and a standard deviation of 1.00degreesC.
Nat2105 [25]

Answer:

P(-2.05

And we can find this probability with this difference

P(-2.05

And we can see the figure in the plot attached.

Step-by-step explanation:

Let X the random variable that represent the redings on thermometers of a population, and for this case we know the distribution for X is given by:

X \sim N(0,1)  

Where \mu=0 and \sigma=1

We are interested on this probability

P(-2.05

We can use the z score formula given by:

z=\frac{x-\mu}{\sigma}

Using this formula we got:

P(-2.05

And we can find this probability with this difference

P(-2.05

And we can see the figure in the plot attached.

Solve the radical equation. square root 6n-11= n – 3 Which solution is extraneous? A.)2
Anvisha [2.4K]
ANSWER


D) 10

EXPLANATION

We want to solve the radical equation,

\sqrt{6n - 11}  = n - 3

Square both sides,



6n - 11 = (n - 3) ^{2}

Expand brackets on right hand side,

6n - 11 =  {n}^{2}  - 6n + 9

Rewrite in general quadratic equation form,

{n}^{2}  - 12n  + 20 = 0

Factor to obtain,

(n - 2)(n - 10) = 0

Apply the zero product principle to get,

n = 2 \: or \: n = 10


We put n=2 into the equation to get,

\sqrt{6(2) - 11}  = 2 - 3


1 =  - 1


This statement is false, hence 2 is an extraneous solution


We put n=10, to get

\sqrt{6(10) - 11}  = 10 - 3


\sqrt{49}  = 7


7 = 7


This is true, hence the only solution is
n = 10
