Answer:

C

Step-by-step explanation:

the unit right below yards is ft so we can mark out A

we also know that there are 3 feet in 1 yard and that in order for the unit yard to cancel out, the 1 yard needs to be the denominator to 3 feet, so we can mark out D

the unit right below feet is inches and we know that there are 12 inches in one foot, so we can mark out B

this leaves us with C

If the die is rolled then the probability of the roll is a prime number is [tex]\frac{4}{10}=\frac{2}{5}[/tex]. The probability that the same number would appear twice on the dice is [tex]0.01[/tex], and the expected value of the roll is [tex]5.5[/tex].

Expected value (EV), which is based on a random variable's probability distribution, describes the long-term average level of that variable. The expected value of a stock or other investment is a crucial factor in investing and is taken into account while performing scenario analysis. The anticipated value is an extension of the weighted average in probability theory. Informally, the anticipated value is the arithmetic mean of a significant number of outcomes of a random variable that were independently chosen. Find the anticipated value by [tex]E(X)[/tex]. Simply multiply each value of the discrete random variable by its probability, then add the results to get the value, or mean, of the random variable. The equation is provided as [tex]E(X)[/tex]=μ=Σ[tex]XP(X)[/tex]. Expected value is calculated by multiplying each outcome's value by the probability.

Total Number of outcomes is [tex]10[/tex]. And the number of prime number is [tex]4 \ \ i.e.\ (2,3,5,7)[/tex]. So the probability of a prime number is [tex]\frac{4}{10}=\frac{2}{5}[/tex]

The expected value is ×[tex]XP(X)= 0*\frac{1}{10}+1 * \frac{1}{10} + 2*\frac{1}{10} +3*\frac{1}{10} +4*\frac{1}{10} +5*\frac{1}{10} +6*\frac{1}{10} +7*\frac{1}{10} +8*\frac{1}{10} +9*\frac{1}{10} \\ =0+\frac{1}{10}+\frac{2}{10}+\frac{3}{10}+\frac{4}{10}+\frac{5}{10}+\frac{6}{10}+\frac{7}{10} +\frac{8}{10}+\frac{9}{10} \\ =\frac{1+2+3+4+5+6+7+8+9}{10}=\frac{55}{10}=5.5[/tex]

If the dice is rolled twice the probability that the same number is obtained is [tex]\frac{1}{10}*\frac{1}{10}=\frac{1}{100}=0.01[/tex]

Answer:

The correct option is;

Magnitude of 8 and direction angle equal to 0°

Step-by-step explanation:

The magnitude of a vector is given by the distance from the initial point of the vector, (which id the starting point) to the final point of the vector, which is the end point of the vector

From the graph, the starting point of the vector = (-2, 2·√2)

The end point of the vector from the graph = (6, 2·√2)

The magnitude of the vector = √(6 - (-2))² = 6 - (-2) = 6 + 2 = 8

The direction of the vector = arctan((The y-component of the vector)/(The y-component of the vector))

∴ The direction of the given horizontal vector = arctan(0/8) = arctan(0) = 0°

Answer:

A - Magnitude of 8 and direction angle equal to 0°.

Step-by-step explanation:

11.  Point (0,4) m=2

 y-y1 = m(x-x1)

 y - 4 = 2(x -0 )

  y-4 =2x

  y = 2x+4

12.  (3,5) and (9,3)

 m = (3-5) / (9-3)

 m = -2 / 6 = -1/3

y-y1 = m(x-x1)

y - 5 = (-1/3) (x - 3)

3y -15 = -(x-3)

3y = -x + 3 +15

3y = -x +18

13.  y = -x/3 + 6

14.  3x - 5y = 15

        -5y = -3x +15

         divide by -5 throughout

    y = (3/5)x - 3

This is 4 quadrants picture

Answer: -0.6

Step-by-step explanation:

The value of the integers computed are 25 and 125.

It should be noted that from the information given, 4² is given as 16 and 4³ is given as 64. We are to find another example that illustrates the information.

The number to use here is 5.

In this case, 5² will be 5 × 5 = 25

5³ will be 5 × 5 × 5 = 125

Therefore, the value of the integers computed are 25 and 125.

Average number of shoppers waiting at checkout is 7.

Average:

Average means the ratio of the sum of all given observations to the total number of observations.

Given,

Little’s law can be applied to any part of the store, such as a particular department or the checkout lines.

The store owner determines that, during business hours, approximately 84 shoppers per hour make a purchase and each of these shoppers spend an average of 5 minutes in the checkout line.

Let,

r is shoppers/minute

T is average time spend by shoppers in minutes

N average number of shoppers.

So, Here, shoppers/hour =84.

Hence, the value of r

r = 84 / 60

And the value of

T = 5

So, the average number of shoppers waiting at checkout is calculated as,

N = r x T

N = (84/60) x 5

N = (84/12) x 1

N = 7

Therefore, the average number of shoppers waiting at checkout is 7.

Because a die has six sides. So you have six chances to get a 4 again.

Percentage error in computing volume is 10%;

r = 6 cm;

Possible measurement error , dr = ±0.1;

dr = 0.1-(0.1) = 0.2 cm;

Volume, V = 4/3 πr³ -(1)

Differentiate w.r.t. r;

dV/dr = 4πr²;  -(2)

Divide (2) by (1);

dV/V = 3 (dr/r)

Put value of r = 6 cm, dr = 0.2 cm;

dV/V = 0.1

Percentage error in computing volume = dV/V × 100% = 10%

Step-by-step explanation:

Answer:

y=¾+8

Step-by-step explanation:

Using the approach y-y1=m(x-x1),where m is the slope defined by ∆y/∆x

So ∆y/∆x=y2-y1/x2-x1

m=6-3/0-(-4)

m=¾

Now plug in m=¾ into the approach and simplify

y-3=¾(x-(-4))

y-3=¾(x+4) Multiply through by 4

4y-12=3x+12 Transpose it for y

4y=3x+12+12
