The five-number summary for scores on a statistics exam is: 35, 68, 77, 83 and 97. In all, 196 students took this exam About how many students had scores between 68 and 83?
The five-number summary consists of the minimum value, the first quartile, the median, the third quartile, and the maximum value.
The interquartile range is the difference between the third and first quartiles. Interquartile range (IQR) = Q3 – Q1, where Q3 is the third quartile and Q1 is the first quartile. The 5-number summary for scores on a statistics exam is given below:
Minimum value = 35
First quartile Q1 = 68
Median = 77
Third quartile Q3 = 83
Maximum value = 97
The interval 68–83 is the range between Q1 and Q3.
Thus, it is the interquartile range.
The interquartile range is calculated as follows:IQR = Q3 – Q1 = 83 – 68 = 15
The interquartile range of the scores between 68 and 83 is 15. Therefore, the number of students with scores between 68 and 83 is roughly half of the total number of students. 196/2 = 98.
Thus, the approximate number of students with scores between 68 and 83 is 98.Answer: a. 98

The Galen Middle School is building a new bicycle storage shed in the school yard. On a carpenter's blueprint, the scale reads 1 in. = 3 ft. The frame for a doorway on the blueprint is shown as a in. Wide and 2a in. High. When the shed is built, what will be the actual dimensions of the doorway
Answer:
Width = 3a
Height = 6a
Step-by-step explanation:
Given the following :
Scale = 1 in = 3 feets
Doorway frame on blueprint= a inches wide ; 2a inches High
Actual dimension of the doorway:
Since 1 in represent 3 feets
Actual doorway frame dimension will be :
Width = 3 * a = 3a
Height = 3 * 2a = 6a

Solve for z. Assume the equation has a solution for z. -4z + 1 = bz + c
Answer:
z=c-1/-4-b
Step-by-step explanation:
-4z+1=bz+c
out objective is to factor out z, so we can get rid of that b in order to solve for z.
-4z-bz=c-1
we can now factor by z
z(-4-b)=c-1
z=c-1/-4-b
make sure you dont forget restrictions
b cant equal -4
3(3) +0.75(2) = (3+0.75)x
Answer:
x=2.8
Step-by-step explanation:
Simplify
3(3) = 9
0.75(2) =1.5
Add
9+1.5=10.5
Simplify again

What is the slope of the line y = –2? a 0 b -2 c
Answer:
Zero
y=2 is a horizontal line, which has a slope of zero. x is the only variable that is changing, as y is always equal to 2 . Since we have no change in y , we have no "rise", therefore the slope is zero.
Answer:
slope = 0
Step-by-step explanation:
y = - 2 represents a horizontal line parallel to the x- axis.
Since the x- axis has a slope of zero then slope of y = - 2 is zero
x−2=3x−1 pls someone help
Answer:
x = - 1/2
Step-by-step explanation:
x - 2 = 3x - 1 We have to subtract x from both sides of the equation and we have to add 1 to both sides of the equation.
-1 = 2x Divide 2 from both sides of the equation
x = - 1/2 <-- This is your answer

What is the value of variable m and what relationship is used?
Answer:
The value of the variable m is 14
The relationship is used → 5m - 28° = m + m + m
Step-by-step explanation:
In the given figure
∵ An angle is divided into 3 equal angles
∵ One angle of these equal angles measures m
∴ That means every one of these equal angles measures m
∵ The measure of the angle which divided into 3 equal angles is 5m - 28°
→ That means its measure equal the sum of the measures of
the 3 equal angles
∴ 5m - 28 = m + m + m
→ Add the like terms in the right side
∴ 5m - 28 = 3m
→ Add 28 to both sides
∵ 5m - 28 + 28 = 3m + 28
∴ 5m = 3m + 28
→ Subtract 3m from both sides
∵ 5m - 3m = 3m - 3m + 28
∴ 2m = 28
→ Divide both sides by 2
∵ [tex]\frac{2m}{2}=\frac{28}{2}[/tex]
∴ m = 14
The value of the variable m is 14
The relationship is used → 5m - 28° = m + m + m
What is 1/4=1/12+1/z
Answer:
[tex]\boxed {z = 6}[/tex]
Step-by-step explanation:
Solve for the value of [tex]z[/tex]:
[tex]\frac{1}{4} = \frac{1}{12} + \frac{1}{z}[/tex]
-The variable [tex]z[/tex] cannot equal to [tex]0[/tex] since division by zero is undefined. SO, you multiply both sides by [tex]12z[/tex], which is the least common multiple of [tex]4[/tex], [tex]12[/tex], and [tex]z[/tex]:
[tex]3z = 12z \times (\frac{1}{12}) + 12[/tex]
[tex]3z = z + 12[/tex]
-Take [tex]-z[/tex] and subtract it from [tex]3z[/tex]:
[tex]3z - z = z - z + 12[/tex]
[tex]2z = 12[/tex]
-Divide both sides by [tex]2[/tex]:
[tex]\frac{2z}{2} = \frac{12}{2}[/tex]
[tex]\boxed {z = 6}[/tex]
So, the value of [tex]z[/tex] of [tex]6[/tex].
