Answer:

Prob (Arrive before 7.30) =  14 / 25 ; Prob (Arrive after 7.30) = 11 / 25

Step-by-step explanation:

Prob (Arrive before 7.30) = No. of days before 7.30 arrival / Total work days

= 28 / 50  = 14 / 25

Prob (Arrive after 7.30) = No. of days after 7.30 arrival / Total work days

= (50 - 28) / 50 = 22 / 50 = 11 / 25

or , 1 - Prob (Arrive before 7.30) = 1 - 14/25 = (25 - 11) / 25 = 11/ 25

A prairie dog left its burrow 5 feet underground and started digging deeper into the ground. It digs straight down at a constant
SpyIntel [72]

Building and solving an equation to model the situation, it is found that it takes 4 min for the prairie dog to reach 13 feet underground.

  • Initially, the dog is 5 feet underground.
  • Each minute, the dog goes 2 more feet underground.

Hence, the underground height of the dog after t seconds is given by:

h(t) = 5 + 2t

The time it takes for the dog to reach 13 feet underground is <u>t for which h(t) = 13</u>, hence:

h(t) = 5 + 2t

13 = 5 + 2t

2t = 8

t = \frac{8}{2}

t = 4

It takes 4 min for the prairie dog to reach 13 feet underground.

The coordinates of rectangle ABCD are A(1, 2), B(4, 5),C(9, 0) and D(6, -3). What is the area of the rectangle? 18 square units
Natali5045456 [20]
In order to find the area of a rectangle, the formula is L*W (Length multiplied by Width). Our goal is to find these two measurements, so we will take the following steps:
1) Plot the coordinates on a graph (I have attached a visual guide)
2) Using the Pythagorean Theorem, or the Distance formula we can find the length and width: \sqrt{(x_{2}-x_{1} )^{2} +(y_{2}-y_{1} )^{2}
3) We will use these values in the Area formula for a rectangle (L*W)
4) After solving the Area formula with the values retrieved from the Distance Formula we find that the area is roughly 30 units squared.
