The modal class, or mode class, is the class that has the highest frequency. Visually on a bar graph or histogram, it is the bar that is the tallest.
In this case, the highest frequency is 65 which corresponds to the class 30-40. The third frequency is the highest, so the third class is the modal class.
Answer: The interval 30-40 is the modal classPLEEASE I REALLY NEED HELP!!!!

What is the slope, the Y-intercept and the equation for this graph??
Answers
Answer:
equation of the line: y=1/2x-1
slope :1/2x
y intercept: -1
Step-by-step explanation:
using y1-y2/x1-x2:
-1-0/0-2= -1/-2=1/2
the slope is 1/2.
plug in the numbers from the given points to find the y intercept:
-1=1/2•0+b
b= -1
the y intercept is -1.
with that, you've gotten the slope and the y intercept, which means you just have to plug them into y=mx+b.
so, the equation of the line is y=1/2x-1
What is the point slope of a line with the slope 4 that contains the point (-3, -4) ?
A. y + 4 = -4 (x + 3)
B. y - 4 = -4 (x - 3)
C. y - 4 = 4 (x - 3)
D. y + 4 = 4 (x + 3)
Answers
Answer:
Correct choice: D.
[tex]y+4=4(x+3)[/tex]
Step-by-step explanation:
The point-slope form of the equation of a line is:
[tex]y-k=m(x-h)[/tex]
Where m is the slope and (h,k) is a point through which the line passes.
According to the question, the slope of a line is m=4 and it contains the point (-3,-4), thus, replacing the values:
[tex]y-(-4)=4(x-(-3))[/tex]
Operating:
[tex]\boxed{y+4=4(x+3)}[/tex]
Correct choice: D.

Jack reads his book for 8 minutes before school and 10 minutes after school. He attends school Monday through Friday. Which equation shows how many minutes Jack reads his book in two weeks? A. (8 × 5) + (10 × 5) = 40 + 50 = 90 minutes B. (8 × 8) + (10 × 10) = 64 + 100 = 164 minutes C. (8 × 10) + (10 × 10) = 80 + 100 = 180 minutes D. (8 × 14) + (10 × 14) = 112 + 140 = 252 minutes
Answers
Answer:
(8 × 10) + (10 × 10) = 80 + 100 = 180 minutes
Step-by-step explanation:
It is given that, Jack reads his book for 8 minutes before school and 10 minutes after school.
No of days between Monday to Friday = 5
No of days between Monday to Friday in 2 weeks = 10
We need to find how many minutes Jack reads his book in two weeks.
For 10 days, before school = (8 × 10) min = 80 minutes
For 10 days, after school = (10 × 10) min = 100 minutes
It means, total time will be :
T = (8 × 10) min + (10 × 10) min
T = 80 + 100
T = 180 minutes
Hence, the correct option is (C).

Answers
Answer:
6/15 ÷ 6
Step-by-step explanation:
Martin is an after school math tutor
He noticed that 6 people still needed help on 2/5 of the time that was left
Martin wrote the expression
2/5 ÷ 6
This expression can be used to determine the number of persons who still need help
Therefore the expression that is equivalent to Martin's expression is
= 6/15 ÷ 6
Using 3 to divide both 6 and 5 will give
2/5 ÷ 6
Hence the expression which is equivalent to Martin's expression is 6/15 ÷ 6

6x + 5 = 3x + 14
Answers
Answer:
x = 3
Step-by-step explanation:
Step 1: Subtract 3x from both sides.
6x + 5 − 3x = 3x + 14 − 3x
3x + 5 = 14
Step 2: Subtract 5 from both sides.
3x + 5 − 5 = 14 − 5
3x = 9
Step 3: Divide both sides by 3.
[tex]\frac{3x}{3} = \frac{9}{3}[/tex]
x = 3

The solution of the linear equation with a single variable 6x + 5 = 3x + 14 will be 3.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.
The equation is given below.
6x + 5 = 3x + 14
Simplify the equation, then we have
6x + 5 = 3x + 14
6x - 3x = 14 - 5
3x = 9
x = 3
The solution of the linear equation with a single variable 6x + 5 = 3x + 14 will be 3.

the prices of stock A at 9am was $12.18 since then the price has been increasing at the rate of $0.06 each hour. At noon the price of stock B was $12.68. It begins to descrease at the rate of $0.09 per hour. If the 2 rates continue in how many hours will the prices of the two stocks be the same?
Answers
Answer:
3.33hours
Step-by-step explanation:
Where the number of hours = h
the prices of stock A at 9am was $12.18 since then the price has been increasing at the rate of $0.06 each hour.
The Algebraic expression =
$12.18 + $0.06 × h
12.18 + 0.06h
At noon the price of stock B was $12.68. It begins to descrease at the rate of $0.09 per hour.
$12.68 - $0.09×h
12.68 - 0.09h
If the 2 rates continue in how many hours will the prices of the two stocks be the same?
Stock A = Stock B
12.18 + 0.06h = 12.68 - 0.09h
Collect like terms
0.06h + 0.09h = 12.68 - 12.18
0.15h = 0.5
h = 0.5/0.15
h = 3.3333333333 hours
h = 3.33hours
