Six friends are sharing 8 cups of lemonade. If they share the lemonade equally, how many cups will each friend get? simplify your answer to a mixed number
Answer:
Step-by-step explanation:
Divide the 8 cups between 6 people: 8/6 = 1.333
As a mixed fraction, that is 1(1/3)
As an improper fraction (that you didn't ask for but whatever), it's 4/3
Each friend gets [tex]1\frac{1}{3}[/tex] cups of lemonade.
What is Division?A division is a process of splitting a specific amount into equal parts.
Given that Six friends are sharing 8 cups of lemonade.
The friends share 8 cups lemonade equally.
We need to find the number of cup each friend will get.
To find this we have to divide eight by six.
In this questions we are splitting 8 cups among 6 friends.
Divide 8 by 6
8/6
Now divide numerator and denominator by 2
4/3
Now let us convert this to mixed fraction
[tex]1\frac{1}{3}[/tex]
Hence, each friend gets [tex]1\frac{1}{3}[/tex] cups of lemonade.

A painter charges $20 for every hour that he paints. Let h represent the number of hours he paints and e represent his earnings. Select all the statements that are true.
Answer:
the 3 correct ones are b,c,e
Answer:
See below.
Step-by-step explanation:
He earns $20 per hour, so when you multiply 20 by h number of hours, you get the amount he earns for working h hours.
The equation is
e = 20h
A is false.
B
e = 20h
20h = 500
h = 25
B is true.
C is false. He earns $20 per hour, not 20h dollars per hour.
D
e = 20h
For 10 hours, h = 10.
e = 20 * 10 = 200
He earns $200 for 10 hours.
D is false.
E
If he raises his hourly rate by $2, he will earn $22 per hour. The new equation is
e = 22h
E is true.

Serenity practices the piano 1036 minutes in 4 weeks. If t represents the total time she practices for any number of days, d, write a proportional equation for t in terms of d that matches the context
Answer:
The proportional equation is [tex]t = 37d[/tex]
Step-by-step explanation:
Serenity practices the piano 1036 minutes in 4 weeks.
Each week has 7 days, so 4 weeks = 4*7 = 28 days.
The amount of minutes she practices per day is given by:
[tex]\frac{1036}{28} = 37[/tex]
So, after d days, the total amount of time she will have practiced is given by:

A grocery store manager claims that 75% of shoppers purchase bananas as least once a month. Technology was used to simulate choosing 150 SRSs of size n = 100 from a population of shoppers where 75% buy bananas. The dotplot shows pˆ = the sample proportion of shoppers who bought bananas in the past month. A random sample of 100 shoppers from the store were selected and 64 bought bananas in the past month. Does this sample provide evidence that the grocery store manager overstated the true proportion? Justify your answer.
Answer:
P-value = 0.0333
At 5% level of significance;
0.0333 < 0.05
Therefore, we reject null hypothesis H₀ at 5% level of significance,
We conclude that proportion of shoppers who bought bananas at least once in the past month is overstated
Step-by-step explanation:
Given the data in the question;
To test whether population proportion p is overstated;
Null hypothesis H₀ : p = (75%) = 0.75
Alternative hypothesis H₁ : = < (75%) < 0.75
now, sample proportion p" = 64 / 100 = 0.64
from the dot plot below, we will determine the p-value for test { P(p" < 0.64)}
so, the number of times p"<0.64 in 150 simulations is 5
Hence; P(p" < 0.64 ) = 5 / 150 = 0.0333
P-value = 0.0333
At 5% level of significance;
0.0333 < 0.05
Therefore, we reject null hypothesis H₀ at 5% level of significance,
We conclude that proportion of shoppers who bought bananas at least once in the past month is overstated
This sample provide evidence that the grocery store manager overstated the true proportion P-value = 0.0333.
Given data in the question:
To test whether population proportion p is overstated; Null hypothesis H₀ : p = (75%) = 0.75 Alternative hypothesis H₁ : = < (75%) < 0.75Now, sample proportion p" = 64 / 100 = 0.64
From the dot plot below,
we will determine the p-value for test { P(p" < 0.64)} The number of times p"<0.64 in 150 simulations is 5Therefore:
P(p" < 0.64 ) = 5 / 150 = 0.0333 P-value = 0.0333
At 5% level of significance;
0.0333 < 0.05
Therefore, we reject null hypothesis H₀ at 5% level of significance,
We conclude that proportion of shoppers who bought bananas at least once in the past month is overstated.

A skateboard costs $240. The sales tax on the skateboard is $12. What the percent of the sales tax?
Answer:
5%
Step-by-step explanation:
12 divided by 240 is 0.05, which is a PERCENTAGE FRACTION (as I like to call it).
This means that you can easily make this into a percentage.
Example Percentage Fractions:
A whole number, like 1 for example, is 100% or more.
The number 1 is 100%, and 2 is 200% and 4.25 is 425%
But since 12 divided by 240, in this problem, is 0.05, it is 5%.
Example are:
0.08 is 8%
0.02 is 2%
0.43 is 43%
0.79 is 79%
It's pretty simple.

Nine bands are to perform at a weekend festival. Suppose you want to determine how many different ways there are to schedule their appearances. Would you use a combination or a permutation?
Answer:
permutation
Step-by-step explanation:
Analyzing the information in the question above, it is correct to say that it is necessary to use permutation, since the ORDER matters, since there is a need to program the band's appearances.
Permutation can be understood as an arrangement in which n = p, where n is the number of elements in the set and p is the number of available elements.
Therefore, the permutation of nine bands is:
Pn = n!
P9 = 9!
p9 = 362880

are any two of the three triangles similar? if so write the appropriate similarity statement.
Answer:
Angle ABC is similar to PQR.
Postulate is Side side, side similarity
Step-by-step explanation:
In triangle ABC, AC:AB = 4/5 = 0.8
In triangle PQR, PR:PQ = 8/10 = 0.8
Looking at the triangle PQR carefully, we can deduce that QR = PR.
Thus; QR:PQ = 8/10 = 0.8.
Also,BC/AB = 4/5 = 0.8
Also, PR/RQ = 8/8 = 1 and AC/CB = 4/4 = 1
Both triangles have the same proportion of their sides and thus we can say they are similar.
Postulate used is Side, Side, Side similarity.
