Answer: The mean hours the groups of teens spent studying is little bit greater for 15- to 16-year old teen or about same .
The range range for the two groups of of teens is greater for 13- to 14-year old teens.
Step-by-step explanation:
We know that the mean of a data is given by :-
[tex]\text{Mean}=\dfrac{\text{Sum of all observations}}{\text{Number of observations}}[/tex]
Range = largest observation - least observation
From the given table :
The mean hours spent by 13- to 14-year olds is given by :-
[tex]\text{Mean}=\dfrac{87}{10}=8.7[/tex]
[tex]\text{Range=12-2=10}[/tex]
The mean hours spent by 15- to 16-year olds is given by :-
[tex]\text{Mean}=\dfrac{89}{10}=8.9[/tex]
[tex]\text{Range=12-4=8}[/tex]
The mean hours the groups of teens spent studying is little bit greater for 15- to 16-year old teen or can say about same.
The range range for the two groups of of teens is greater for 13- to 14-year old teens.

Jason ate one third of a pizza for dinner, and his brother ate one sixth of the same pizza.What portion of the pizza was left over?
Jason and his brother ate a total of one half of the pizza when their portions, one third and one sixth respectively, are combined. Therefore, one half of the pizza was left over.
To calculate this, we add the fractions of the pizza that were consumed together:
Jason's portion: 1/3
Brother's portion: 1/6
We find a common denominator, which is 6 in this case, and sum the fractions:
(2/6) + (1/6) = 3/6
After simplifying 3/6, which is one half, we subtract this from the whole pizza to find the portion that is left:
1 - 1/2 = 1/2
Therefore, one half of the pizza was left over after Jason and his brother had their portions.

The simplification 6x + 8 = 7x + 13 is one solution. The correct option is A.
What is one solution?There is just one correct answer to some equations. There is only one value for the variable in these equations that causes the equation to be true.
If you solve an equation and the result is a variable equal to a number, the equation has just one solution. There is only ever one real number solution to a quadratic problem. A system is deemed consistent if it has at least one solution.
A consistent system is independent if it only has one solution. A consistent system is dependent if there are an endless number of possible solutions. Both equations show the same line on a graph when you plot the equations.
Therefore, the correct option is A, one solution.

In the figure, lines a, b, and c are parallel and m∠4=48° .
Drag and drop the correct angle measure for each angle.
The values of each angle are:
∠1 = 48
∠2 = 132
∠3 = 132
∠5 = 48
We have,
∠4 = 48
∠4 and ∠5 are corresponding angles.
so,
∠5 = 48
Now,
∠3 and ∠4 make a straight angle.
So,
∠3 + ∠4 = 180
∠3 = 180 - 48
∠3 = 132
Now,
∠2 and ∠3 are alternate angles.
So,
∠2 = ∠3 = 132
Now,
∠1 and ∠2 make a straight angle.
So,
∠1 + ∠2 = 180
∠1 = 180 - 132
∠1 = 48
Thus,
∠1 = 48
∠2 = 132
∠3 = 132
∠5 = 48

What are the amounts of interest and maturity value of a loan for 150,000 at 6 1/2% simple interest for 3 years?
The formula for computing the amount of simple interest is:
I = Prt
Where P = principal amount of the loan
r = interest rate of the loan
t = duration of the loan
Substituting the amounts in the formula,
I = (150,000) (6.5%) (3)
= 29,250
To compute for the maturity value, you have to add the interest to the principal amount:
Maturity value = 150,000 + 29,250 = 179,250
To calculate the amount of interest and maturity value of a loan, use the formula: Interest = Principal × Rate × Time. In this case, the interest is $29,250 and the maturity value is $179,250.
Explanation:To calculate the amount of interest and maturity value of a loan, we can use the formula:
Interest = Principal × Rate × Time
Maturity Value = Principal + Interest
In this case, the principal is $150,000, the rate is 6.5% (0.065 in decimal form), and the time is 3 years.
Step 1: Calculate the interest
Interest = $150,000 × 0.065 × 3 = $29,250
Step 2: Calculate the maturity value
Maturity Value = $150,000 + $29,250 = $179,250
Therefore, the amount of interest is $29,250 and the maturity value of the loan is $179,250.

Which formula can be used to describe the sequence? , −4, −24, −144,...
Answer:
[tex]An= -4(6)^{n-1}[/tex]
Step-by-step explanation:
−4, −24, −144,...
There is no common difference
-24/-4= 6
-144/ -24= 6
common ratio = 6
when there is a common ratio then it is an Geometric sequence
[tex]An= a1(r)^{n-1}[/tex]
a1 is the first term = -4
r is the common ratio = 6
