Answer:

50% percent chance the ball will be yellow

Step-by-step explanation:

Find the amount of all the balls-24 and the amount of yellow balls-12

Then divide the number of yellow balls by the number of total balls.

12÷24=0.5

0.5=50%

Answer:

Part A is ≤ means less than OR equal to. < only means less than

Part B is 9

Step-by-step explanation:

A: Because it would equal 19, and 19 is equal than 19. 4(5) - 1 would equal 19, which is equal to 19, and not less than. ≤ means less than or equal to. < means less than. So its not true.

B: 47 - 2, 45. Then 5 x 9 equals 45. So 5 x 9 equals 45, then add 2 would equal 47.

The 555 points plotted below are on the graph of y=\log_b{x}y=log
adell [148]

Answer:

See attachment for graph

Step-by-step explanation:

<em>See comment for correct question</em>

Given

y = \log_bx

Required

The corresponding points on y =b^x

On the graph, we have:

(x_1,y_1) \to (1,0)

(x_2,y_2) \to (2,1)

(x_3,y_3) \to (4,2)

(x_4,y_4) \to (8,3)

(x_5,y_5) \to (16,4)

First, we solve for b in y = \log_bx

Using laws of logarithm, the equivalent of the above is:

x = b^y

(x_2,y_2) \to (2,1) implies that:

2 = b^1

2 = b

Rewrite as:

b =2

So, the equation y =b^x becomes:

y = 2^x

Using the same values of x, we have:

(x_1,y_1) = (1,2)

(x_2,y_2) = (2,4)

(x_3,y_3) = (4,16)

(x_4,y_4) = (8,256)

(x_5,y_5) = (16,65536)

sydney predicted the that it would snow 5 days Last winter but it actually snowed one week. What is the percent error?
babunello [35]

There is 28.57% error in Sydney's calculations.

Step-by-step explanation:

Given,

John's prediction = Approx value = 5 days

Actually snowed = Exact value = 1 week = 7 days

Percent error = \frac{|aprrox-exact|}{exact}*100

Percent\ error=\frac{|5-7|}{7}*100\\Percent\ error=\frac{|-2|}{7}*100\\Percent\ error=\frac{|-200|}{7}\\Percent\ error=28.57\%

There is 28.57% error in Sydney's calculations.
