Answer:
52 students ride a bus to school
Step-by-step explanation:
Step 1: Our output value is 260.
Step 2: We represent the unknown value with x.
Step 3: From step 1 above $260 = 100%.
Step 4: Similarly, x = 20%.
Step 5: This results in a pair of simple equations:
260 = 100%(1).
x = 20%(2).
Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have
[tex]\frac{260}{x}[/tex] = [tex]\frac{100}{20}[/tex]%
Step 7: Again, the reciprocal of both sides gives
[tex]\frac{x}{260}[/tex] = [tex]\frac{20}{100}[/tex]
⇒x=52$
Therefore, 20% of 260 is 52.
Hope this helps! :)

The number of students who ride a bus is 52.
What is a percentage?The percentage is calculated by dividing the required value by the total value and multiplying by 100.
Example:
Required percentage value = a
total value = b
Percentage = a/b x 100
Example:
50% = 50/100 = 1/2
25% = 25/100 = 1/4
20% = 20/100 = 1/5
10% = 10/100 = 1/10
We have,
Total number of students = 260
The number of students who ride a bus.
= 20% of 260
= 1/5 x 260
= 52
Thus,
The number of students who ride a bus is 52.

Answer: t= 11.5
Step-by-step explanation: 5 + (-11.5+3) = 3.5
Answer:
T = -3.7
Step-by-step explanation:
We begin with the given equation.
5(t+3)=-3.5
Distribute 5 throughout parentheses.
5t + 15 = -3.5
Move 15 to the other side and switch signs.
5t = -3.5 - 15
Combine like terms.
5t = -18.5
Divide by 5t.
t = -3.7

Based on the table, do the data support the use of a normal model to approximate population characteristics?
A Yes, because the sum of the relative frequencies is 1.00.
B
Yes, because the distribution of relative frequencies is very close to the empirical rule for normal models.
с
No, because the values are negative and normal models are used for positive values.
D
No, because the distribution of relative frequencies is very far from the empirical rule for normal models.
E
No, because the sample size and the population parameters are not known.
Answer:
B
Step-by-step explanation:
I know because I know that how
The correct answer is D. No, because the distribution of relative frequencies is very far from the empirical rule for normal models.
What is Mean?The sum of all values divided by the total number of values determines the mean (also known as the arithmetic mean, which differs from the geometric mean) of a dataset. The term "average" is frequently used to describe this measure of central tendency.
To determine if the data supports the use of a normal model to approximate population characteristics, we need to examine the relative frequencies and see if they exhibit a bell-shaped or normal distribution.
Looking at the table, we see that the relative frequencies are not symmetrical and do not follow the empirical rule for normal models.
The largest relative frequency is in the interval from -0.28 to -0.25, and the frequencies decrease as we move away from this interval. Additionally, there are negative values in the data, which is not a characteristic of normal models.
Therefore, the correct answer is D. No, because the distribution of relative frequencies is very far from the empirical rule for normal models.

slope of 0 and passes through (7, 4)
Answer:
y = 4
Step-by-step explanation:
Assuming you require the equation of the line.
A line with a slope of zero is a horizontal line parallel to the x- axis, with equation
y = c
where c is the value of the y- coordinates the line passes through
The line passes through (7, 4 ) with y- coordinate 4, thus

Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store. The 0.425 kg box was on sale for $3.59, the 0.74 kg box was on sale for $4.88, and the 0.95 kg box was on sale for $7.29. Which box of cookies was the best buy? Explain your reasoning. To get you started: 3.59 : 0.425 1kg/ 0.425kg= 2.35 0.425 x 2.35= 1kg $3.59 x 2.35= $8.44 3.59 : 0.425 -> $8.44 : 1kg
Answer:
The best buy is the 0.74 kg box
Step-by-step explanation:
Kamilah noticed that three different-sized boxes of the same cookies were on sale at a grocery store.
We find the unit price for 1 box
a) The 0.425 kg box was on sale for $3.59
= 1 kg = $3.25/0.425
= $7.6470588235
b) the 0.74 kg box was on sale for $4.88,
1 kg = $4.88/0.7$
= $6.5945945946
c) the 0.95 kg box was on sale for $7.29.
1 kg = $7.29/0.95
= $7.6736842105
Which box of cookies was the best buy?
The best buy is the 0.74kg box because 1kg of this box has a lesser price compared to the others.

Lisa is buying a computer for $1,500. The sales tax rate is 8.5%. Which expression should be used to calculate t, the total cost for the computer including tax?
Answer:
t=$1627.5Step-by-step explanation:
Step one:
given data
price of computer= $1500
sales tax= 8.5%
Step two
Let us compute the amount in tax
tax= 8.5/100*1500
=0.085*1500
=$127.5
Let the total cost be t
hence
t=1500+0.085*1500
t=1500+127.5
t=$1627.5

if 72 is 40% what is 100%?
Answer:
180
Step-by-step explanation:
If 40% = 72, 100% can be found like so:
40% = 72
100% = [tex]\frac{100}{1}[/tex] * [tex]\frac{72}{40}[/tex]
You can reduce 40 and 100 by 20 (or probably more, but I'll use 20)
So now we have:
[tex]\frac{50}{1}[/tex] * [tex]\frac{72}{20}[/tex] = [tex]\frac{3600}{20}[/tex]Divide, and you get 180.
To check, we can find 40% of 180.

A gardening company sells clay flower pots and plastic flower pots. There must be at least 2 pots in each shipment, but there cannot be more than 8 in a shipment. Additionally, the shipment must weigh less than 100 lbs. Each shipment container weighs 20 lbs., and there is 1 lb. of packing material. A clay flower pot weighs 15 lbs., whereas a plastic flower pot weighs 7.5 lbs.
(A) Write a system of inequalities that represent the constraints on the number of pots that can be included in one shipment.
The system of inequalities can be obtained from the given information
on the allowable weights and number of pots.
The correct responses:
The system of inequalities that represent the constraint on the number
of pots that can be included in one shipment are;
2 ≤ x + y ≤ 815·x + 7.5·y ≤ 79 lbs.Methods used to find the system of inequalitiesThe inequality that represents the number total number of clay, T, in each shipment is 2 ≤ T ≤ 8
The inequality that represents weight of each shipment is w < 100 lbs
The weight of each shipment container = 20 lbs
The weight of the packing material = 1 lb
Therefore;
The maximum weight of the flower pots = 100 lbs - 21 lbs = 79 lbsThe weight of each clay flower pot = 15 lbs
The weight of each plastic flower pot = 7.5 lbs
Let "x" represent the number of clay flower pot included in one shipment
and let "y" represent the number of plastic flower pot included in one
shipment, we have;
The system of inequalities that represent the constraint on the number of pots that can be included in one shipment are as follows;
2 ≤ x + y ≤ 815·x + 7.5·y ≤ 79 lbs.Learn more about inequalities here:
https://brainly.com/question/10868639
We will find the system of inequalities:
C*15 lb + P*7.5lb < 79 lb
2 ≤ P + C ≤ 8
How to write a system of inequalities?
First, we need to define the variables that we will be using, these are:
C = number of clay pots.P = number of plastic pots.From the first restriction, we have that:
2 ≤ P + C ≤ 8
The other restriction says that the weight must be less than 100lbs:
W < 100lbs
Where the weight is:
W = C*15 lb + P*7.5lb + 20lb + 1lb
Where 20lb is the weight of the container and 1lb is the weight of the packing material, then we have:
C*15 lb + P*7.5lb + 20lb + 1lb < 100lb
We can subtract 21 lb in both sides to get:
C*15 lb + P*7.5lb < 100 lb - 21 lb
C*15 lb + P*7.5lb < 79 lb
So we got our two inequalities, then the system is:
C*15 lb + P*7.5lb < 79 lb
2 ≤ P + C ≤ 8

Answer:
P(green) =1/4
P(orange)=1/2
Step-by-step explanation:
I'm assuming this is probability but it\s been a while, so i'm not sure
number one is a square being divided into half and then one half is being divided into quarters. (as shown by the dotted lines and right angle)
so the probablity of landing in green is 1/4, because it is one fourth of the square.
the probability of the orange is 1/2 because it is 1/2 of the square
The same logic would apply to the "circle" i can see in the next problem. 120 degrees is 1/3 of 360, 90 is 1/4, and so on.
Hope that helps.
