The distance between points (X7, Yı) and (4, 8) is the square root of (x7 - 8)2 +
serious [3.7K]

Answer:

B. False

Step-by-step explanation:

Given

Points: (x_7 - y_i),(4,8)

Required

Is the distance between them \sqrt{(x_7 - 8)^2 + (y_1 - 4)^2}

Given that there are two points, the distance between them is calculated using

Distance = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2}

In this case;

(x_1,y_1)= (x_7 - y_i)\\(x_2,y_2) =(4,8)

Substitute these in the given formula

Distance = \sqrt{(4- x_7)^2 + (8 - y_1)^2}

Comparing this with the given formula, both are not the same;

Hence, the formula is false and the correct formula is of the form \sqrt{(4- x_7)^2 + (8 - y_1)^2}

Roll a number cube. If the number cube comes up odd, you win the same number of points as the number on the cube. If the number
laila [671]

Answer:

–0.5

Step-by-step explanation:

Expected value is found by multiplying the probabilities of each roll by the amount won or lost with each roll.

The odd rolls are 1, 3 and 5.  The probability of rolling a 1 is 1/6, and the value is 1; this gives us 1/6(1) = 1/6.

The probability of rolling a 3 is 1/6, and the value is 3; this gives us 1/6(3) = 3/6.

The probability of rolling a 5 is 1/6, and the value is 5; this gives us 1/6(5) = 5/6.

Rolling any even number gives us the same value.  The probability of rolling an odd number is 3/6, and the value is -4; this gives us 3/6(-4) = -12/6.

Together we have

1/6+3/6+5/6-12/6 = 4/6+5/6-12/6 = 9/6-12/6 = -3/6 = -0.5

Erica can thoroughly analyze the company’s monthly credit card statements
lbvjy [14]

Answer:

240 minutes or 4 hours

Step-by-step explanation:

So if it takes Erica 80 minutes to analyze the company's monthly credit card statements, she will get 30/80 of it done in 30 minutes.

If it takes Alexa 2 hours to analyze the company's monthly credit card statements, she will get 30/120 of it done in 30 minutes.

Add 15 to each of the fractions because they analyze the company's monthly credit card statements with Mack for 15 more minutes.

So you have 45/80 and 45/120.

Now add both fractions by finding the lowest common denominator which is 240.

135/240 + 90/240 = 225/240

So Mack did the remaining 15/240.

Now to find how long it would take him to analyze the company's monthly credit card statements by himself divide 240 by 15 which is 16.

Then multiply

15 x 16 = 240

so it would take him 240 minutes or 2 hours.
