Answer:

1. 3 2. 22 3. 0

Step-by-step explanation:

First Box: Jada only has $15 dollars she can spend

If she chooses to buy 6 individual songs that would cost her $3.

because each individual song cost $0.50 so (6 times 0.5= 3)

Since Jada only has $15 we need to subtract 3 from 15 to find out how much money she has left. So, 15-3=12. Jada has $12 left

An album cost $4 dollars each so Jada can only buy 3 albums with $12 because 12 divided 4 is 3.

Answer to first box: 3

Second Box: Jada only has $15 dollars she can spend

If she chooses to buy 1 album that would cost her $4.

because each individual song cost $4 so (4 times 1= 4)

Since Jada only has $15 we need to subtract 4 from 15 to find out how much money she has left. So, 15-4=11. Jada has $11 left

An individual song cost $0.50 dollars each so Jada can only buy 22 individual songs with $11 because 11 divided by 0.5=22.

Answer to second box: 22

Third Box: Jada only has $15 dollars she can spend

If she chooses to buy 30 individual songs that would cost her $15.

because each individual song cost $0.50 so (30 times 0.5= 15)

Since Jada only has $15 we need to subtract 15 from 15 to find out how much money she has left. So, 15-15=0. Jada has $0 left

An album cost $4 dollars each so Jada can only buy 0 albums with $0 because 0 divided 4 is 0.

Answer to third box: 0

Construct the cumulative frequency distribution for the given data.

tino4ka555 [31]

Answer:

Age Frequency Cumulative Frequency

Less than 30 27 27

Less than 40 37 27 + 37 = 64

Less than 50 1 1 64 + 11 = 75

Less than 60 3 75 + 2 = 77

Less than 70 5 77 + 5 = 82

Less than 80 1 82 + 1 = 83

Less than 90 2 83 +2 = 85

Step-by-step explanation:

Given:

The Frequency Distribution table of ages of best actresses when award was won

To find:

Construct the cumulative frequency distribution

Solution:

In order to construct cumulative frequency distribution for the given data, each frequency from above table is added to the sum of the previous frequencies. For example, frequency for Less than 40 is 37 and the previous frequency (less than 30) is 27 so in order to calculate cumulative frequency 27 i.e. previous frequency is added to 37 (frequency of less than 30). The complete table is given above.

PLEASE HELP ASAP 35 POINTS

podryga [215]

Your answer is A

It cannot be C because the line y > -2 uses the (>) greater than symbol.

When equations have a greater than symbol, they are graphed using a dotted line.

It cannot be D because the line is y ≤ - l x-1 l

with the less than or equal to sign (≤) , you use a solid line to graph

With the greater than symbol for y > -2 , the shaded region must be above this line.

With the less than or equal to sign in y ≤ - l x-1 l , the shaded region must be below the line.

Hope I helped - message me if you have any questions :)

the height in feet above the ground of an arrow after it is shot can be modeled by y=-16r^2+63r+4.Can the arrow pass over a tree

miss Akunina [59]

Answer:

yes

Step-by-step explanation:

y=-16r^2+63r+4

maximum value of y :

y'=0

-32r +63=0

r= 63/32

y = -16(63/32)²+63(63/32)+4

= -4 + 124 + 4 = 124 ft

124 > 68

the Arrow can pass over the tree
