The probability of picking a dime and then a penny without replacement is 0.0651.
What is the probability?Probability is used to determine the odds that a random event would happen. The probability the event happens is 1 and the probability that the event does not happen is 0.
The more likely the event is to occur, the closer the probability value would be to 1. The less likely it is for the event not to happen, the closer the probability value would be to zero.
The probability of picking a dime and then a penny without replacement = (number of dimes / total number of coins) x (number of pennies / total number of coins - 1)
(19 / 73) x (18 / 72) = 0.0651

what is the total capacity in gallows of a rectangular tank 5 meters in height knowing that it will hold 200 liters per foot?
729.1 is the total capacity in gallows of a rectangular tank .
What is rectangle?
The internal angles of a rectangle, which has four sides, are all exactly 90 degrees. At each corner or vertex, the two sides come together at a straight angle. The rectangle differs from a square because its two opposite sides are of equal length.1 Foot height can store = 200 ltrs
Height of tank = 5 m = 500/30.48 = 16.4 ft
Total Capacity = 200 * 16.4 =3280.8 ltr
There were several gallons in use. One gallons is roughly = 4.5 ltr
Hence the capacity in gallon = 3280.8/4.5 = 729.1

The graph to the right uses cylinders to
represent barrels of oil consumed by two
countries. Does the graph distort the data or
does it depict the data fairly? Why or why not?
If the graph distorts the data, construct a
graph that depicts the data fairly.
Does the graph distort the data? Why? Or Why not?
A. Yes, because 3D objects always distort the data in graphs.
B. Yes, because the graph incorrectly uses objects of volume to represent the data.
C. No, because the graph is technically correct.
D. No, because the proportions are accurate.
The correct option regarding whether the graph distorts the data is:
B. Yes, because the graph incorrectly uses objects of volume to represent the data.
What is the correct graph for the amounts in the problem?When we are showing absolute amounts of two or more data-sets, the correct representation should be of graphs like histograms or bar graphs.
For this problem, the objective is to show the daily oil consumption in two countries, and they are shown as the volumes of a cylinder, which gives the idea that the amount in country A is considerable more than 4 times country B, that is, distorting the data.
Conversely, a bar graph or a histogram would show the right ratio between these two amounts.
Hence the correct option is:
B. Yes, because the graph incorrectly uses objects of volume to represent the data.

A person who wants to get in shape goes to a local gym that advertises 62 training sessions for $1109. Find the cost of 94 training sessions.
The cost of 94 training sessions is $1681.3.
A unit means one thing. A unit rate means the rate of something. Write this as a ratio with a denominator of 1. For example, if you ran 70 meters in 10 seconds, you ran an average of 7 meters in 1 second. A ratio of 70 yards in 10 seconds and 7 yards in 1 second are both rates, but 7 yards in 1 second is a unit rate. The unitary method is a method of finding the value of one unit and then finding the value of the required number of units.Suppose you go to the market to buy six apples. The shopkeeper told you that he sells 10 apples for 100 rupees. In this case, the apple is the unit and the apple price is the value.
62 training sessions for $1109
1 session = 1109/62
94 sessions = (1109/62) * 94
= $1681 .3
The cost of 94 training sessions is $1681.3.

The values of the set functions after the matching are:
D∩F = FD∩E = EDU(E∩F) = DD∩(E∩F) = {16}D∩(EUF) = {1,,4,9,12.14,16,18,35,36,47,64,81}What do we mean by different types of sets' functions?The intersection of two sets is represented by ∩.This refers to shared values between the sets under consideration.U represents the union of two sets.This includes all values from all sets considered.So, we have D = {x | x is a whole number}.
Then: D = {0,1,2,3,4,5,6,7,8,.........}Similiarly, E = {x | x is a perfect square < 100}.
So: E = {1,,4,9,16,35,36,47,64,81}Similarly, F = {x | x is an even number between 10 and 20}.
Then: F = {12,14,16,18}Now, D∩E = The common values from sets D and E.
Here we have: = E (all perfect square < 100 )D∩F = F
Where: This means all even numbers between 10 and 20}Now, D∩(E∩F) = {16}.
Then: E∩F = {16}Hence, The only value common to both set D and E∩F is 16.DU(E∩F) = D ( This means all whole numbers)
Then we can say: E∩F = {16}D∩(EUF) = {1,,4,9,12.14,16,18,35,36,47,64,81}
We obtain: EUF = {1,,4,9,12.14,16,18,35,36,47,64,81}Therefore, the values after the matching are:

Pablo had 638 grams of cashew nuts and 594 grams of peanuts. He mixed the nuts and packed them into 7 packets. Each packet of nuts had a mass of 120 grams. How many grams of nuts did Pablo have left?
The nuts left with Pablo after using 840 g of nuts to make 7 packets is 392 g.
We are given that:
Pablo has
Cashew nuts = 638 g
Peanuts = 594 g
He now has mixed the nuts.
Total amount of nuts will be calculated by using addition.
Total amount of nuts = T = 638 g + 594 g
T = 1232 g
He has made a total of 7 packets and in each packet, he has put 120 g of nuts.
Total nuts used = 7 × 120 g = 840 g
Nuts left with Pablo = 1232 g - 840 g
Nuts left = 392 g
Therefore, we get that the nuts left with Pablo after using 840 g of nuts to make 7 packets is 392 g.

Bill’s spelling list is 3 words long at the start of the school year. Each month, his teacher adds 8 words to the list.
Let m represent the number of months since school began and w represent the total number of spelling words.
This relationship can also be shown in a table. Complete the equation that represents between m and w.
Based on the fact that m represents the number of months and w is the total number of spelling words, the equation that represents the relationship between m and w is w = 8m + 3
How to find the equation?The first thing to find is the slope of the relationship. This can be found as:
= ( 51 - 43) / (6 - 5)
= 8 / 1
