Move two choices to the blanks to correctly complete the sentences.
Pavel [41]

Answer:

(A) There should have been 5 outcomes of HT

(B) The experimental probability is greater than the theoretical probability of HT.

Step-by-step explanation:

Given

S = \{HH,HT,TH,TT\} -- Sample Space

n(S) = 4 --- Sample Size

Solving (a); theoretical outcome of HT in 20 tosses

First, calculate the theoretical probability of HT

P(HT) = \frac{n(HT)}{n(S)}

P(HT) = \frac{1}{4}

Multiply this by the number of tosses

P(HT) * n= \frac{1}{4} * 20

P(HT) * n= 5

<em></em>

Solving (b); experimental probability of HT

Here, we make use of the table

P(HT) = \frac{n(HT)}{n(S)}

P(HT) = \frac{6}{20}

P(HT) = 0.30 ---- Experimental Probability

In (a), the theoretical probability is:

P(HT) = \frac{1}{4}

P(HT) = 0.25 ---- Experimental Probability

By comparison;

0.30 > 0.25

If the sum of three consecutive numbers is 36. Find the numbers.
aleksandrvk [35]

Answer:

11, 12, 13

Step-by-step explanation:

x is the first number

(x + 1) is the second number

(x + 2) is the third number

x + x+1 + x+2 = 36

3x + 3 = 36

3x = 36 - 3

3x = 33

x = 11  ← the first number

the second number  = x + 1 = 11 + 1 = 12

the third number = x + 2 = 11 + 2 = 13

A line has a y-intercept and a slope of 0. What is the line’s equation?
Gnom [1K]
The answer is y= -1

When the slope is 0, we refer to the line as a constant function. In slope intercept form, the line is equal to y = mx + b

 

"m" is the slope, and "b" is the y-intercept.

 

Let's replace those in the function.

 

y = 0*x - 1

 

0 multiplied by anything is 0

 

y = 0 - 1

y = -1
