What is the surface area of a 5 cm cube?

the probability that the two cards dealt to Satara (without replacement) will both be hearts is 7%

Total Number of cards left in the deck = 10

Number of hearts left in the deck = 3

Probability = (required outcome / Total possible outcomes)

Required outcome = hearts card in the deck

Without replacement, deal Satara two cards as follows:

The chance that the first card is a heart:

P(first card being hearts) = necessary result / all possible results

P(first card is a heart) equals 3/10.

The probability that the second card is a heart:

It cannot be replaced because:

Required result = (3 - 1). = 2

The total number of outcomes is (10 - 1) = 9 P(the second card is a heart) = 2 /9

The likelihood that the two cards are hearts is (3/10 x 2/9) = 6/90 = 0.0666 x 100% = 6.66%

= 7% (nearest whole number)

The mean for a given set of observations is 10.

The mean is the average of a set of variables in mathematics and statistics. The mean may be calculated in a variety of methods, including the simple arithmetic mean (add the numbers and divide the total by the number of observations), geometric mean, and harmonic mean. A data set's mean (average) is calculated by summing all of the numbers in the set and then dividing by the number of values in the set. When a data collection is arranged from least to largest, the median is the midway value. The mode is the number that appears the most frequently in a data collection.

Linear equations are easy to solve .They are a type of mathematical equation that involve one or more variables, in which all terms are of the first degree.

The general form of a linear equation is Ax + B = C, where A, B and C are numerical coefficients and x is a variable. Linear equations can be solved by first rewriting the equation in slope-intercept form, which is y = mx + b, where m is the slope and b is the y-intercept. Then, the y-intercept can be determined by substituting in a value for x and solving for y. To find the slope, two points on the line must be chosen, and the formula            m = (y2 - y1)/(x2 - x1) is used to calculate the slope. Once the slope and y-intercept are known, the equation can be written in its slope-intercept form and solved for x.

Linear equations can also be solved using the substitution method, where one of the variables is substituted with a numerical value. This method can be used when the equation is already written in its standard form, Ax + B = C. By solving for x, the value of x can be found and substituted back into the equation to find the value of C.

Finally, linear equations can also be solved using the elimination method, which is used when there are two linear equations with two unknowns. The two equations are added together, and the coefficients of one of the variables are eliminated. This method is useful for solving systems of linear equations.

Answer: w = 4

Step-by-step explanation:

To solve the equation 10(w+3) = 70, we will work to get w by itself:

1. Divide by 10. This will get us closer to w.

(10( w + 3))/10 = 70/10

w + 3 = 7

2. We now have the equation w + 3 = 7. All we need to do now to get w by itself (or isolate it) is to subtract 3.

(w + 3) - 3 = 7 - 3

w = 7 - 3

w = 4

3. We can check our solution by inputting our found value, w = 4, into the equation.

10( 4 + 3 ) = 70

10(7) = 70

70=70

Because both sides of the equation are true, our solution of w = 4 is correct.

Answer: w = 4

Step-by-step explanation:

10(w+3)=70

10w + 30 = 70

Answer:

Step-by-step explanation:

If you're wondering about what percent of 212 is 400, the answer is 189.3%. This means that 400 is 89.3% higher than 212. It’s easy to see that, when compared side by side, 400 is a much bigger number, almost twice as great as 212. Put another way, if you divide 400 by 212, you get 1.89—that’s your answer! Clearly, 400 is a great deal larger than 212 and this difference in size can be expressed as a percentage increase of 189.3%.

Approximately 19.05% of 212 is 400.

Answer:

Step-by-step explanation:

Solution for 212 is what percent of 400:

212:400*100 =

(212*100):400 =

21200:400 = 53

Now we have: 212 is what percent of 400 = 53

Question: 212 is what percent of 400?

Percentage solution with steps:

Step 1: We make the assumption that 400 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$.

Step 3: From step 1, it follows that $100\%=400$.

Step 4: In the same vein, $x\%=212$.

Step 5: This gives us a pair of simple equations:

$100\%=400(1)$.

$x\%=212(2)$.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS

(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{400}{212}$

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{212}{400}$

$\Rightarrow x=53\%$

Therefore, $212$ is $53\%$ of $400$.  

the answer is 53 or 188.68%

Three commonly used types of graphs are bar graphs, Pie Chart, and line graphs. Every sort of graph is appropriate for displaying a one-of-a-kind kind of records.

Graph:

The term graph is a pictorial illustration of facts in an organized way. Charts are normally fashioned from different data factors that represent the link among two or more matters.

Bar Graph:

A bar graph is a chart that displays complete data in rectangular bars, with the height of the bars proportional to the values ​​they represent. Chart bars can be displayed vertically or horizontally. A bar chart, also called a bar chart, is a graphical representation of grouped data. It is a method of data processing. Bar Graph are great for displaying data independent of each other and do not need to be in any particular order when displayed. Bars provide a visual indicator for comparing amounts in different categories. A bar chart has two lines, the horizontal and vertical axes (also called x-axis and y-axis), a title, labels, and a scale range.

Pie Chart:

Pie Chart is a chart type that visually represents data in a pie chart. It is one of the most commonly used charts for representing data with attributes of circle, sphere, and angle data to represent real-world information. The shape of the pie chart is circular, the circle represents all the data and the slices of the pie represent portions of the data and are plotted separately.

For Example: A full circle represents a value of 100. Divided into 10 slices or sectors. Different colors represent the ingredients used to prepare the cake. What is the exact amount of each component represented by a particular color in the pie chart below?

Solution: As you can see, the pie he is divided into 10 segments or sectors. To calculate the exact amount of ingredients added to the cake, divide the value across sectors.

H. 100 in sectors. So 100 ÷ 10 = 10.

Line graph:

A line chart is a graphical representation of changes that occur over a period of time. A line chart has a horizontal axis called the x-axis and a vertical axis called the y-axis. The x-axis usually has a period of time that measures the quantity of a particular thing or item on the y-axis. Line charts are useful for analyzing trends, whether the quantity on the y-axis is increasing or decreasing over time. A line chart clearly shows an uptrend or a downtrend.

Step-by-step explanation:

You want the difference between the largest and smallest 5-digit numbers whose digits are from the set {1, 2, 3} and include each of these at least once. The numbers cannot be divisible by 2 or 3.

The number will be divisible by 3 when its sum of digits is a multiple of 3. Since 1, 2, and 3 are prescribed digits, the remaining two digits must not have a total of 3 or 6. The largest possible remaining digits are {2, 3}, and the smallest remaining digits are {1, 1}. (Using {3, 3} for the largest digits would give a number divisible by 3.)

The number will be divisible by 2 if the least significant digit is 2. The largest and smallest digits are not 2, so that will not be an issue.

The largest number will place the largest available digit in the place with the highest place value: 33221.

The smallest number will place the smallest available digit in the place with the highest place value: 11123.

The desired difference is the difference of these numbers:

  33221 -11123 = 22098 . . . . difference of largest and smallest
