What is the least common denominator of 5/12 and 4/18

Answers

The least common denominator of 12 and 18 is 36.

Given that fractions $(5)/(12)$ and $(4)/(18)$ .

Fraction: It is of the form p/q where q is not equal to zero.

∴p/q , q ≠ 0

Fractions: $(5)/(12)$ and $(4)/(18)$

LCM of the denominator: 12 and 18

LCM of 12 and 18 = 36

Fraction 5/12:

Multiply numerator and denominator by 3.

$(5 * 3)/(12 * 3) = (15)/(36)$

Fraction 4/18:

Multiply numerator and denominator by 2.

$(4 * 2)/(18 * 2) = (8)/(36)$

Thus the common denominator of the fraction is 36.

What is the slope of the line that contains these points?x 15,17,19,21 y -10,2,14,26

Answers

Answer:

Step-by-step explanation:

The slope (m) can be found using the formula ...

m = (y2 -y1)/(x2 -x1)

Any pair of points will do. We can use the first two.

m = (2 -(-10))/(17 -15) = 12/2

m = 6

The slope of the line is 6.

Answer: 6

Step-by-step explanation:

Find the points on the given curve where the tangent line is horizontal or vertical. (Assume 0 ≤ θ < π. Enter your answers as a comma-separated list of ordered pairs.)r = 6 cos(θ)

Answers

Answer:

point of horizontal tangent is $(0^(o),6)$ and point of vertical tangent is $(-15.17^(o),5.79)$

Step-by-step explanation:

For a horizontal tangent it's slope should be zero thus

$r=6cos(\theta )\n\n(dr)/(d\theta)=-6sin(\theta )$ $\therefore -6sin(\theta)=0\n\n \Rightarrow \theta =0,\pi$

Thus the ordered pair of $(\theta ,r)$ becomes (0,6) at this point tangent is horizontal

For a vertical tangent it's slope should be $(\pi )/(2)$

Again differentiating the given curve we get

$r=6cos(\theta )\n\n (dr)/(d\theta)=-6sin(\theta )$ $\therefore -6sin(\theta)=(\pi )/(2)\n\n\Rightarrow \theta =sin^(-1)(-\pi )/(12)$

$\therefore \theta =-15.17^(o)$

Thus the ordered pair of vertical tangent becomes ( $\theta =-15.17^(o),5.79)$

The required probability that a bottle has a volume greater than 992 mL is 0.84134. Option C is correct

Given that,
A bottler of drinking water fills plastic bottles with a mean volume of 999 milliliters (ml) and a standard deviation of 7 ml. The fill volumes are normally distributed. What is the probability that a bottle has a volume greater than 992 mL, is to be determined

What is probability?

Probability can be defined as the ratio of favorable outcomes to the total number of events.

We use Z-statistic to find out the probability,

z = (x − μ) / σ

x = raw score = 992 mL
μ = population mean = 999 mL
σ = standard deviation
z = [992 − 999]/7
z = -1

P-value from Z-Table:

P(x<992) = 0.15866

P(x>992) = 1 - P(x<992) = 0.84134

Thus, the required probability that a bottle has a volume greater than 992 mL is 0.84134

#SPJ2

Answer:

0.8413

Step-by-step explanation:

Find the z score.

z = (x − μ) / σ

z = (992 − 999) / 7

z = -1

Use a chart or calculator to find the probability.

P(Z > -1)

= 1 − P(Z < -1)

= 1 − 0.1587

= 0.8413

Can someone please answer c. I’ve been trying for 30 mins and can’t understand it

Answers

Answer: 7

Step-by-step explanation:

For c, we are given this sum from 1 to 3 of $(n^2)/(2)$ . 1/2 is a constant , therefore, we can move it outside of the summation.

*I hope you can understand what I'm saying. I can't figure out how to type in summations into the equations section.

1/2∑₁³n²

This means you would multiply the sum of n² from 1 to 3 by 1/2.

We are told n=1 to n=3 so we would plug 1, 2, 3 into n.

1²=1

2²=4

3²=9

We would add them together since that is what the sum sign tells us to do.

1+4+9=14

Now that we know the sum, we multiply it with 1/2

14/2=7
