Stacy uses a spinner with six equal sections numbered 2, 2, 3, 4, 5, and 6 to play a game. Stacy spins the pointer 120 times and
2 answers:
Answer:
The solution is given below;
Step-by-step explanation:
The computation is shown below:
There is six equal sections are numbered i.e. 2, 2, 3, 4, 5, and 6.
And, Number of Outcome of 2 on the Spinner is 2
Also, total Number of Sections is 6
As the winning spin is a 2
So, The theoretical probability of winning
= 2 ÷6 × 100
= 33.33%
Now
There is a total no of trials be 120
And, the number of outcome of 2 be 30
So, the experimental probability is 30 ÷ 120 = 1 ÷ 4 × 100 = 25%
As 33.3%>25%, this represent that the theoretical probability of winning would be greater.

Answer:
Proportion states that the two fractions or ratios are equal
As per the statement: Mrs. Hwang is taking her vehicle to the shop to have the gas tank expanded by 10 gallons. Now, it costs her $42.56 to fill the tank. Once the new tank is in, it will cost her $72.96
Let the tank size now be x
Since, the gas tank expanded by 10 gallons = x + 10
by definition of proportion ;
by cross multiply we get;
using distributive property;
Subtract 42.56x from both sides we get;
Divide both sides by 30.4 we get;
x = 14
Therefore, the tank is her now is, 14 gallons
Answer:
The predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
Step-by-step explanation:
The least square regression line is used to predict the value of the dependent variable from an independent variable.
The general form of a least square regression line is:
Here,
<em>y</em> = dependent variable
<em>x</em> = independent variable
<em>α</em> = intercept
<em>β</em> = slope
The regression line to predict the life expectancy of men in a country from the life expectancy of women in that country is:
Compute the life expectancy of men in a country in which the life expectancy of women is 70 years as follows:
Thus, the predicted life expectancy of men in a country in which the life expectancy of women is 70 years is 65.33 years.
