Answer:

Before Tim ate any of the jellybeans, here are numbers: 

pineapple or p  =10

raspberry or  r = 10

orange or o = 10

 

Tim has eaten 6 orange and 4 pineapple jellybeans. Hence, what's left are: 

 p = 10-4 =6

o = 10-6 =4

r = 10 so now total jelly beans are 20

So the probability of getting a raspberry is: 

p(r) = number of r/total

10/20 or 50%

Estimate the size of a crowd walking in a charity fundraising march that occupies a rectangular space with dimensions of 10 feet
jolli1 [7]

Answer:

4000 is size of a crowd walking in a charity fundraising March.

Step-by-step explanation:

Given:

Dimensions of rectangular space 10 feet by 12000 feet

So we can say that,

Length = 1200 ft

Width = 10 ft

Now we will calculate the area of rectangular space which is given by

Hence Area will be = length\times width= 10\ ft \times 1200 \ ft= 12000 \ ft^2

Now we know that 40 people occupy a rectangle measuring 10 feet by 12 feet.

Length = 12 ft

Width = 10 ft

Area = length\times width= 10\ ft \times 12 \ ft= 120 \ ft^2

It says that 40 people are occupied in 120 ft^2

So how many people will be there in 12000 ft^2

By using unitary method we get,

Number of people = \frac{40\times 12000 \ ft^2}{120 \ ft^2} = 4000 \ peoples

Size of a crowd walking in a charity fundraising March is 4000.

13. f(x) = x^4<br> - 9x2 -22x - 24
Anna007 [38]

Answer:

x = 4 or x = -2

Step-by-step explanation:

Solve for x over the real numbers:

x^4 - 9 x^2 - 22 x - 24 = 0

The left hand side factors into a product with three terms:

(x - 4) (x + 2) (x^2 + 2 x + 3) = 0

Split into three equations:

x - 4 = 0 or x + 2 = 0 or x^2 + 2 x + 3 = 0

Add 4 to both sides:

x = 4 or x + 2 = 0 or x^2 + 2 x + 3 = 0

Subtract 2 from both sides:

x = 4 or x = -2 or x^2 + 2 x + 3 = 0

Subtract 3 from both sides:

x = 4 or x = -2 or x^2 + 2 x = -3

Add 1 to both sides:

x = 4 or x = -2 or x^2 + 2 x + 1 = -2

Write the left hand side as a square:

x = 4 or x = -2 or (x + 1)^2 = -2

(x + 1)^2 = -2 has no solution since for all x on the real line, (x + 1)^2 >=0 and -2<0:

Answer:  x = 4 or x = -2
