Shown here are four frequency distributions. Each is incorrectly constructed. State the reason why.
Answer/Step-by-step explanation:
a. The the class width for the 1st, 2nd, 3rd, and 5th row equal 5 in the frequency distribution. Whereas, in the 4th row, the class width is 4 (49 - 45). This makes the construction incorrect.
b. Here, the upper limit of each consecutive class was used as the lower limit if the next class. For example, 9 is a member of the first class, which is the upper limit if the class in the first row, it ought not to be included as a member of the next class in the second row.
c. In the 3rd row, the lower limit of the class should be 133, NOT 138.
d. Different class width were used.
Row 1 class width = 13 - 9 = 4
Row 2 class width = 19 - 14 = 5
Row 3 class width = 25 - 20 = 5
Row 4 class width = 28 - 26 = 2
Row 5 class width = 32 - 29 = 3
The reason for all the frequency distribution is given below and this can be determined by using the given data.
Check all the options in order to determine the reason for the incorrect construction.
A) The given frequency table is given below:
Class Frequency
27-32 1
33-38 0
39-44 6

B) The given frequency table is given below:
Class Frequency
5-9 1
9-13 2
13-17 5
17-20 6
20-24 3

C) The given frequency table is given below:
Class Frequency
123-127 3
128-132 7
138-142 2
143-147 19

A leaf hangs from a branch 12 feet in the air. It falls to the ground at a rate of 0.25 feet per second. Which graph could represent the leaf’s height in feet as a function of time, in seconds, after leaving the branch?
Answer:
No graphs was presented but its the last one shown in the photo
The leaf's height as a function of time is determined as h(t) = 12 - 0.25t - 4.9t².
Equation for the motion of the leaf
The equation for the motion of the leaf is calculated as follows;
h = vt + ¹/₂gt²
where;
h is the height of fallv is the initial velocityt is the time of motionThe leaf's height as a function of time is given as;
h(t) = 12 - 0.25t - 4.9t²
Due to presence of gravity, the decline in the height of the leaf will be gradual.

Samantha's mother spent $78 at a farmers market. She bought the same number of pounds of apples for $1.50 per lb as tomatoes for $2.50 per lb. She also bought half that weight of a farmers cheese that sold for $4.00 per lb. The number of pounds of peaches she bought for $3.00 per lb was one more pound than the farmers cheese. How many pounds of each product did Samantha's mother buy?
Answer:
The number of pounds of apples she bought = 10 pounds
The number of pounds of tomatoes she bought = 10 pounds
The number of pounds of the farmers cheese she bought = 5 pounds
The number of pounds of peaches she bought = 6 pounds
Step-by-step explanation:
The given information are;
The amount that Samantha's mother spent in the market = $78
The number of pounds of apples she bought = The number of pounds of tomatoes she bought
The number of pounds of the farmers cheese she bought = 1/2 of the number of pounds of apples she bought
The number of pounds of peaches she bought = 1 + 1/2 of the number of pounds of apples she bought
The price of the apples = $1.50
The price of the tomatoes = $2.50
The price of the farmers cheese = $4.00
The price of the peaches = $3.00
If we put the number of pounds of the apples she bought = X, we have
X×$1.50 + X×$2.50 + 1/2×X×$4.00 + (1 + 1/2×X)×$3.00 = $78.00
Which gives;
X×$1.50 + X×$2.50 + 1/2×X×$4.00 + $3.00+ 1/2×X×$3.00 = $78.00
[tex]\dfrac{X \times \$15.00 + \$ 6.00}{2} = \$ 78[/tex]
X × $15.00 + $6.00 = $78 × 2 = $156.00
X × $15.00 + $6.00 = $156.00
X × $15.00 = $156.00 - $6.00 = $150.00
X = $150.00/($15.00) = 10 pounds
Therefore;
The number of pounds of the apples she bought = X = 10 pounds
The number of pounds of apples she bought = 10 pounds
The number of pounds of tomatoes she bought = The number of pounds of apples she bought = 10 pounds
The number of pounds of tomatoes she bought = 10 pounds
The number of pounds of the farmers cheese she bought = 1/2 of the number of pounds of apples she bought = 1/2 of 10 = 1/2×10 = 5 pounds
The number of pounds of the farmers cheese she bought = 5 pounds
The number of pounds of peaches she bought = 1 +The number of pounds of the farmers cheese she bought = 1 pound + 5 pounds = 6 pounds
The number of pounds of peaches she bought = 6 pounds.
The solution is: Samantha´s mother bought:
10.71 Lbs of apples10.71 Lbs of tomatoes5.36 Lbs of farmers cheese6.36 Lbs of peachesAs the question of the problem is" How many pounds of each product Samantha´s mother bought" it is convenient to call:
x quantity of pounds of apple ( the same as tomatoes )Samantha´s mother bought y quantity of pounds of farmers cheese Samantha´s mother bought z quantity of pounds of peaches Samantha´s mother boughtAccording to that:
Spent
She spent 78 $ buying
1.50× x + 2.50×x + 4× y + 3 × z = 78 (1)
Now y = x/2 and z = y + 1
By substitution in equation (1) we get
3.50× x + 4×(x/2) + 3× [( x/2 ) + 1 ] = 78
Solving for x
5.50×x + (3/2)×x + 3 = 78
11×x + 3×x + 6 = 156
14×x = 150
x = 10.71 Lbs
y = 10.71/2 y = 5.36 Lbs
and z = 5.36 + 1 = 6.36 Lbs
z = 6.36 Lbs

Answer:
x=6
Step-by-step explanation:
5-6x=17-8x 5-6x=17-8x
5-6(6)=17-8(6) or 5+2x=17 added 8x to both sides
5-36=17-48 2x=12 subtracted 5 from both sides
-31=-31 x=6 divided both sides by 2
