The perimeter of a playing field for a certain sport is 174 ft. The field is a rectangle, and the length is 45 ft longer than th
Leno4ka [110]

Answer:

21 ft by 66 ft

Step-by-step explanation:

From the question,

P = 2(L+W)............... Equation 1

Where P = Perimeter of the playing Field, L = Length of the playing Field, W = width of the playing Field.

If the Length of the Field is 45 ft longer than the width,

L = 45+W............ Equation 2

Substitute Equation 2 into equation 1

P = 2(45+W+W)

P = 90+4W............. Equation 3

Given: P = 174 ft.

Substitute into equation 3

174 = 90+4W

4W = 174-90

4W = 84

W = 84/4

W = 21 ft.

Substituting the value of W into equation 2

L = 45+21

L = 66 ft.

Hence the dimensions of the playing field is 21 ft by 66 ft

The probability that a student pilot passes the written test for a private pilot's license is 0.7. what is the probability that
zhenek [66]
<span>Probability = 0.063 Fourth try = 0.0973 Let X be the number of failed attempts at passing the test before the student passes. This is a negative binomial or geometric variable with x â {0, 1, 2, 3, . . .}, p = P(success) = 0.7 and the number of successes to to observe r = 1. Thus the pmf is nb(x; 1, p) = (1 â’ p) xp. The probability P that the student passes on the third try means that there were x = 2 failed attempts or P = nb(2, ; 1, .7) = (.3)2 (.7) = 0.063 . The probability that the student passes before the third try is that there were two or fewer failed attmpts, so P = P(X ≤ 2) = nb(0, ; 1, .7) + nb(1, ; 1, .7) + nb(2, ; 1, .7) = (.3)0 (.7) + (.3)1 (.7) + (.3)2 (.7) = 0.973 .</span>

A circle has a diameter with endpoints of (-3, 8) and (7, 4). What is the center of the circle?
Alexeev081 [22]
The center of the circle is expressed as (h,k) in the standard form  of equation. In this case, the diameter endpoints are <span>(-3, 8) and (7, 4). Hence the circle center has coordinates which are the midpoints of the two points. 

x = (-3 + 7) /2  = 2
y = (8 + 4) /2 = 6 

hence the center of the circle is (2,6)</span>

Show your work 2 1/5 × 3 1/8
vesna_86 [32]

Solution

For this case we can do the following:

2\cdot\frac{1}{5}=\frac{2\cdot5+1}{5}=\frac{11}{5}3\cdot\frac{1}{8}=\frac{3\cdot8+1}{8}=\frac{25}{8}

And then if we multiply we got:

\frac{11}{5}\cdot\frac{25}{8}=\frac{55}{8}
