Answer:

P(1.48<X<15.56) ≈ 0.919 ≈ 91.9%

Step-by-step explanation:

2nd+DISTR --> normalcdf

P(1.48<X<15.56) = normalcdf(1.48,15.56,8,4) ≈ 0.919

What is the value of x?<br> 12 units<br> 15 units<br> 20 units<br> 25 units
Firlakuza [10]

Answer:

The answer is 12 units.

Step-by-step explanation:

Looking at the figure we see that

(1).9^2+x^2=SR^2

(2).16^2+x^2=RQ^2 and

(3).SR^2+RQ^2=(9+16)^2

Now from equations (1) and (2) we have values for SR^2 and RQ^2, so we put those into the equation (3) and get:

9^2+x^2+16^2+x^2=(9+16)^2

\rightarrow 337+2x^2=625

\boxed{\therefore x= 12.}

Therefore the answer is 12 units.

Find the first four terms of the sequence given by the following.<br> aₙ=43-3(n-1) n=1,2,3. . .
Serggg [28]

Given :-

  • The general term of a sequence is given by aₙ=43-3(n-1) .

To Find :-

  • The first four terms of the sequence.

Solution :-

The given expression is /

→ aₙ=43-3(n-1)

where n > 0

<u>Finding</u><u> the</u><u> </u><u>first </u><u>term </u><u>:</u>

Substituting n = 1 , we have ,

→ T1 = 43 - 3(1-1)

→ T1 = 43 - 3*0

→ T1 = 43 - 0 = 43

<u>Finding</u><u> the</u><u> </u><u>second</u><u> </u><u>term </u><u>:</u>

Substituting n = 2 , we have,

→ T2 = 43 -3(2-1)

→ T2 = 43 -3*1

→ T2 = 43 -3 = 40

<u>Finding</u><u> </u><u>the </u><u>third </u><u>term</u><u> </u><u>:</u>

Substituting n = 3 , we have,

→ T3 = 43 -3(3-1)

→ T3 = 43 -3*2

→ T3 = 43 -6 = 37

<u>Finding</u><u> the</u><u> </u><u>fourth</u><u> </u><u>term </u><u>:</u>

→ T4 = 43 -3(4-1)

→ T4 = 43 -3*3

→ T4 = 43-9 = 34

<u>Hence</u><u> the</u><u> </u><u>first</u><u> </u><u>four</u><u> terms</u><u> of</u><u> </u><u>the</u><u> </u><u>sequence</u><u> </u><u>are </u><u>4</u><u>3</u><u> </u><u>,</u><u> </u><u>4</u><u>0</u><u> </u><u>,</u><u> </u><u>37</u><u> </u><u>and </u><u>34</u><u> </u><u>.</u>

<em>I </em><em>hope</em><em> this</em><em> helps</em><em> </em><em>.</em><em> </em><em>Let </em><em>me</em><em> know</em><em> if</em><em> you</em><em> </em><em>need </em><em>further</em><em> </em><em>clarification</em><em> </em><em>.</em>

Is the LCM of a pair of numbers ever equal to one of the numbers?
den301095 [7]

Yes.

For example, the LCM of 12 and 36 is 36, because factoring these numbers gives

12 = 2^2 * 3

36 = 2^2 * 3^2

So, to match them, just multiply the twelve by 3, then they're both 36.
