On average, Taub drinks 7/9 of a 12-ounce glass of water in 1/10 of an hour. How many glasses of water does she drink in one hour?
Answers
Answer:
Step-by-step explanation:
7/9
Taub can drink 7/9 glasses in 1/10 of an hr, you want to know how much she can drink in 1 hr
multiply 7/9 by 10 = 70/9
the number line will be:
7/9 14/9 21/9 28/9 35/9 42/9 49/9 56/9 63/9 70/9
1/10 2/10 3/10 4/10 5/10 6/10 7/10 8/10 9/10 10/10
Step-by-step explanation:
We can set up a ratio
\( \frac{7}{9} = \frac{x}{12} \)
Next we cross multiply
\(9x = 84\)
\(x = 9 \frac{1}{3} \)
So he drinks 9 1/3 ounces of water in 1/10. To go from 1/10 to 10/10, you multiply by 10. So we will do that to the ounces.
\(9 \frac{1}{3} \times 10 = 93 \frac{1}{3} \)
Lastly we divide by 12
\(93 \frac{1}{3} \div 12 = 7 \frac{7}{9} \)
I'm not sure how you are suppose to answer it, but here are the options
\(7 \frac{7}{9} = mixed\)
\( \frac{70}{9} = fraction\)
\(7.77 = whole \: number\)

Answer: Range and mean = 8 of both
variance of Set X= 4.7
variance of Set Y= 4.6
Step-by-step explanation:
Two sets of data, set X and set Y are given
a.) Range is the difference of the highest value and the lowest value,
Therefore, Range of set X = 12-4=8
Range of set Y = 12-4=8
Now, Mean of a given data set is the average of all the terms present in the given data set
Mean of set X= Σxif/n = (4+5+6+7+16+18+24)/10 = 8
Mean of set Y= (4+5+7+32+20+12)/10= 8
Therefore, both the data sets has same range and mean.
b.) Standard deviation tells about the variability of the date and is given by,
S.D= σ = √∑ ( X − μ )^2/n
S.D of set X= √(16+9+4+1+0+1+16)/10= √4.7
S.D of set Y= √(16+9+1+0+4+16)/10= √4.6
Variance is the square of S.D, that is, σ^2
Therefore, variance of set X=4.6
variance of set Y= 4.7
c.) The calculated variances of set X and set Y are 4.7 and 4.6 respectively. It implies that the data is more distributed or varied in set X than in set Y. In the other words, data in set Y is more consistent data than of set X.

Madison is ordering a taxi from an online taxi service. The taxi charges $2.50 just for the pickup and then an additional $1.50 per mile driven. How much would a taxi ride cost if Madison is riding for 3 miles? How much would a taxi ride cost that is mm miles long?
Answers
Answer: It would cost Madison $7 to go for a 3-mile ride.
Step-by-step explanation:
Initial fee: $2.50
Per mile: $1.50
Set up an equation where \(x\) = the number of miles driven
Using y = mx + b form:
y = 1.5x + 2.5
How much would a taxi ride cost if Madison is riding for 3 miles?
Simply plug in 3 for x
y = 1.5(3) + 2.5
y = 4.5 + 2.5
y = 7
Therefore, It would cost Madison $7 to go for a 3-mile ride.
How much would a taxi ride cost that is mm miles long?
To solve this plug in the number of miles driven for x and then solve
Madison will cost a total of $7 for his 3 miles riding.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
Summation = addition of two or more numbers or variable
For example = 2 + 8 + 9
Subtraction = Minus of any two or more numbers with each other called subtraction.
For example = 4 - 8
Division = divide any two numbers or variable called division.
For example 4/8
Multiplication = to multiply any two or more numbers or variables called multiplication.
For example 5 × 7.
Given,
Pick up charge = $2.50
Rate of charge per mile = $1.50/ mile
So,
Total charge = pickup charge + number of mile(rate of charge per mile)
Total charge = 2.50 + 3(1.50)
Total charge = $7
Hence "Madison will cost a total of $7 for his 3 miles riding".

Answer:
202.5 cm^2
Step-by-step explanation:
We can calculate the area of the shape by completing it
to a full rectangle or dividing it to a rectangle and triangle.
The second way seems easier
The area of the rectangle is calculated by multiplying length to width
20 × 9 = 180 cm^2
The area of a triangle is calculated by multiplying height to the base and that divided by two
5 × 9 ÷ 2 = 22.5 cm^2
Now add these two 180 + 22.5 = 202.5 cm^2
Answer:
202.5 cm squared
Step-by-step explanation:
To find the area of this figure easier, you can cut the figure like I showed in the attachment below.
The rectangle (purple): 20 times 9 is 180.
The right triangle (light blue): 9 times 5 times 1/2 is 22.5.
All together: 180 plus 22.5 is 202.5 cm squared!
