62.5% just divide 35/56 and multiply by 100

%62.5 you divide the amount of males with the total amount of guests then you will get 0.625 so you put the comma two places behind and add a percentage.

Miguel buys a large bottle and a small bottle of juice. The amount of juice that the manufacturer puts in the large bottle is a

fomenos

Answer:

Pr(X>1540.2) = 0.0655

Step-by-step explanation:

Expected value of large bottle,

E(Large) = 1016

Expected value of small bottle,

E(small) = 510

Expected value of total

E(total) = 1016 + 510 = 1526

So the new mean is 1526

Find standard deviation of new amount by variance

Variance of large bottle,

v(large) = 8^2 = 64

Variance of small bottle,

v(small) = 5^2 = 25

Variance of total

v(total) = 64+25 = 89

So the new standard deviation

sd(new) = sqrt(89) = 9.434

Find probability using the new mean and s.d.

Pr(X>1540.2)

Z score, z = (x-mean)/sd

= (1540.2 - 1526)/9.434

= 1.505

value in z score

P(z<1.51) = 0.9345

For probability of x > 1540.2

P(z > 1.51) = 1 - 0.9345 = 0.0655

The terms of the binomial expansion are written below using the patterns. (m + 2)4 = (1)(m4)(20) + (4)(m3)(21) + (6)(m2)(22) + (

lorasvet [3.4K]

Answer:

$(m + 2)^4 = m^4+ 8 m^3 + 24 m^2 + 32 m + 16$

Step-by-step explanation:

$(m + 2)^4 = (1)(m^4)(2^0) + (4)(m^3)(2^1) + (6)(m^2)(2^2) + (4)(m^1)(2^3) + (1)(m^0)(2^4)$

2^0 is 1 also m^0 is 1

2^2= 4, 2^3= 8 , 2^4= 16

$(m + 2)^4 = (1)(m^4)(1)+ (4)(m^3)(2) + (6)(m^2)(4) + (4)(m^1)(8) + (1)(1)(16)$

$(m + 2)^4 = m^4+ 8 m^3 + 24 m^2 + 32 m + 16$

The length of a rectangle is 4n, and twice as long as the width. the perimeter pf the rectangle is twice as long as that of an e

sattari [20]

2n,perimeter of rectangle is 12n ( width is 2n because length is twice of the width)
1/2 of that ( because the perimeter of the rectangle is twice of the equilateral triangle) is 6n. Since its an equilateral triangle, divide 6n by 3 to get 2n

A carnival has two payment options. Plan A, you pay $10 admission plus $3 for each ride. Plan B, you pay a $20 admission plus $1

stiks02 [169]

<span>Let x = # of rides

Plan A: 10 + 3x

Plan B: 20 + x

if x < 5 rides then plan A is better buy
if x = 5 both plans are the same
if x > 5 then plan B is the best buy

Prove:
x = 6 (rides)

plan A: </span>10 + 3x = 10 + 3(6) = 10+18 = $28
plan B: 20 + x = 20 + 6 = $26
