Answer:

n = 13

Step-by-step explanation:

Divide 1045 spectators by 85:

1045

---------- = 12.29

     85

Obviously it won't suffice to use 12 busses; this 12.29 must be rounded up to 13 busses.  n = 13

Answer:

85n >/= 1,045

Step-by-step explanation:

85 people times n buses has to equal or exceed 1,045 people

85n is greater than or equal to 1,045

85n >/= 1, 045

n >/= 12.29

So, since n has to be greater than or equal to 12.29, and there is no 29/100ths of a bus, they would need 13 buses (in case there's a follow-up question)

A cheese can be classified as either raw dash milk or pasteurized. Suppose that 91​% of cheeses are classified as pasteurized. ​
Marina CMI [18]

Answer:

Step-by-step explanation:

Given that a cheese can be classified as either raw dash milk or pasteurized. Suppose that 91​% of cheeses are classified as pasteurized.

Each cheese is independent of the other and there are only two outcomes.

Hence X = no of cheeses pasteurized is binomial (2,0.91)

a) P(x=2 ) when n=2  is(0.91)^2=0.8281

b) n=6.  

P(x=6) = (0.91)^6=0.5679

c) P(atleast one raw dash milk) = 1-P(all pasteurised)

=0.8281

Since probability is 0.83 it is not unusual.

On Friday, you raked leaves for 4 neighbors, on saturay you raked leaves for 5 neighbors, and on Sunday you raked leaves for 3 n
Jet001 [13]

Answer:

The amount paid by each house is $11.25

Step-by-step explanation:

Let the amount paid by each house is $K

Number of neighbors you worked for on Friday = 4

So the amount paid by all of them = 4K

Number of neighbors you worked for on Saturday = 5,

similarly amount paid = 5K

Number of neighbors you worked for on Sunday = 3,

here amount paid = 3K

Also, in total the amount paid = $135

So, Amount paid on {Friday + Saturday +Sunday} = Total Amount

or, 5K + 4K + 3K = $135

or, 12K = 135

⇒K =135/12 = $11.25

So, the amount paid by each house is $11.25

Lol helppppppppppppp
Dima020 [189]

Answer:

\boxed {x = \frac{10}{c}}

Step-by-step explanation:

Solve for the value of x:

3(cx - 7) = 9

-Divide 9 by 3:

cx - 7 = \frac{9}{3}

cx - 7 = 3

-Add 7 to both sides:

cx - 7 + 7 = 3 + 7

cx = 10

-Take c and divide it on both sides:

\frac{cx}{c} = \frac{10}{c}

\boxed {x = \frac{10}{c}}

Therefore, the value of x is \frac{10}{c}.
