- Abel says (62)3 = 65. Is he correct?<br> Explain.

expeople1 [14]

Answer and Step-by-step explanation:

Abel is incorrect. $(62)3$ denotes that the two terms are being multiplied. Instead of multiplying, Abel added these two terms.

The correct solution would be:

$(62)(3)=186$

What is the recursive formula for this sequence . 10,14,18,22,26

Marrrta [24]

add 4 each time

the nth term is a_n or f(n)

the next term after that is a_{n+1} or f(n+1)

so each term is 4 more than previous

basically

a_{n+1}=4+a_n or

f(n+1)=4+f(n)

The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean μ, the act

cluponka [151]

Answer: 0.3061.

Step-by-step explanation:

Given : The temperature reading from a thermocouple placed in a constant-temperature medium is normally distributed with mean $\mu$ , the actual temperature of the medium, and standard deviation $\sigma$ .

Let X be the random variable that represents the reading of the thermometer.

Confidence level : $=95\%$

We know that the z-value for 95% confidence interval is 1.96.

Then, we have

$-1.96$ $z=\dfrac{X-\mu}{\sigma}$

$\Rightarrow\ -1.96\sigma$

But all readings are within 0.6° of $\mu$ .

So, $1.96\sigma=0.6$

$\Rightarrow\ \sigma=\dfrac{0.6}{1.96}=0.30612244898\approx0.3061$

Hence, the required standard deviation will be

Find the coordinates of the vertices of the figure after the given transformation T <2,4>

tankabanditka [31]

The correct answer is option A which is j'(1,3) , E'( -2,1) and V'( 1,3).

<h3>What is coordinate geometry?</h3>

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis.

Given that:-

The coordinates of the vertices of the figure after the given transformation T <2,4>

So we will transform the points given in the figure.

V(-1,-1) , J(-4,-5) and E(-4,-3).

The transformation will be given as:-

V(-1,-1) → V'(-1+2 , -1 + 4) → V'( 1,3 )

J(-4,-5) → J'( -4 +2 , -5 + 4 ) → J'( -2,-1 )

E(-4,-3). → E'( -4+2 , -3+4 ) → E' ( -2, 1 )

Therefore correct answer is option A which is j'(1,3) , E'( -2,1) and V'( 1,3).
