Based on the tallies and frequencies for the first and last intervals, how many intervals of what length did Jamie use?
a.
4 intervals of 1000 feet
c.
6 intervals of 500 feet
b.
5 intervals of 1000 feet
d.
7 intervals of 500 feet
Answer:
D. 7 intervals of 500 feet
Step-by-step explanation:
Got it right
Jamie used 5 intervals of 1000 feet as per the given data. The correct option is b.
What are tallies and frequencies?A tally chart is a straightforward method of recording and counting frequencies. Each occurrence is represented by a tally mark, and every fifth tally is drawn diagonally to form a five-pointed star.
The first interval has a frequency of 7, which corresponds to the first 7 data points in the list:
1010
1470
1600
2000
2800
1053
1495
The last interval has a frequency of 2, which corresponds to the last 2 data points in the list:
2310
4260
Since there are 25 data points in total, and the first 7 and last 2 have been accounted for, that leaves 16 data points for the remaining intervals.
If Jamie used 1000-foot intervals, each interval would cover a 1000-foot range. The remaining data points range from 1200 to 4200 feet, so they are divided into 1000-2000, 2000-3000, and 3000-4000 foot intervals.
If Jamie used 500-foot intervals, each interval would cover a 500-foot range.
Thus, because the remaining data points range from 1200 to 4200 feet, they are divided into 1000-1499, 1500-1999, 2000-2499, 2500-2999, 3000-3499, 3500-3999, and 4000-4499 foot intervals.

which value if x makes this proportional true? 14/20=56/x A.x=62 B.x=70 C.x=80 D.x=100
==================================================
Work Shown:
Let's cross multiply to get the following
14/20 = 56/x
14*x = 20*56
14x = 1120
x = 1120/14
x = 80
-------------------
As a way to check the answer, we can type 14/20 - 56/80 into the calculator and we should get 0. I'm taking advantage of the rule that if A = B, then A-B = 0. This trick is handy to check if two sides of any equation are equal to one another.
your answer will be 80 pretty sure

Answer:
60
Step-by-step explanation:
The volume of the rectangular prism is V = 64 units³
What is the volume of a prism?A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.
The volume of a prism is the product of its base area and height
Volume of Prism = B x h
where B = base area of prism
h = height of prism
Given data ,
Let the volume of the rectangular prism be represented as V
Now , the height of the prism is H = 4 units
The length and width of the prism is 1 and 16 units respectively
So , the base area of the prism B = 16 units²
Now , Volume of Prism = B x h
On simplifying , we get
The volume of rectangular prism V = 16 x 4
The volume of rectangular prism V = 64 units³
Hence , the volume of the rectangular prism is 64 units³

Pentru sala de mese a scolii s-au adus 12 scaune si 7 mese, plătindu-se 320lei.Știind că 4 scaune costă cât trei mese, află prețul unui scaun și prețul unei mese.
Răspuns:
Costul scaunului = 15
Costul mesei = 20
Explicație pas cu pas:
Dat fiind:
Să prețul scaunelor = c; pretul mesei = t
12c + 7t = 320 - - - (1)
4c = 3t; c = 3/4 t - - - (2)
Introducerea c = 3 / 4t în (1)
12 (3 / 4t) + 7t = 320
9t + 7t = 320
16t = 320
t = 320/16
t = 20
c = 3 / 4t
c = 3/4 (20)
c = 15
Costul scaunului = 15
Costul mesei = 20
