Answer:
0.543 or 54.3%
Step-by-step explanation:
This is an example of a binomial distribution, where the probability of success (playing the particular song) is 0.42, and the number of trials is 6.
To find the probability that the song will be played on at least 3 days out of 6, we need to calculate the probability of the song being played on 3, 4, 5, or 6 days.
Using a binomial probability calculator or formula, we can calculate these individual probabilities:
Probability of the song being played on 3 days out of 6: 0.308
Probability of the song being played on 4 days out of 6: 0.177
Probability of the song being played on 5 days out of 6: 0.052
Probability of the song being played on all 6 days: 0.006
To get the probability of the song being played on at least 3 days out of 6, we add these individual probabilities together:
0.308 + 0.177 + 0.052 + 0.006 = 0.543
Therefore, the probability that the song will be played on at least 3 days out of 6 is 0.543 or 54.3% (rounded to the nearest thousandth).
ou are paid 1.5 times your normal hourly rate for each hour you work over 40 hours in a week. you worked 46 hours this week and earned $612.50. part a: which equation can you use to solve for $x$ , your normal hourly rate? responses $612.50\
The equation to solve for your normal hourly rate is x = (612.5 - 1.5 * 46 + 46 * x) / 40.
In this equation, x represents your normal hourly rate. The first term in the parentheses, 612.5, is your total earnings for the week. The second term, 1.5 * 46, represents the overtime pay you received for working 6 hours over 40 hours. The third term, 46 * x, represents the amount you earned for your 40 hours of regular pay. The final term, 40, represents the number of hours you worked at your regular rate. By dividing both sides of the equation by 40, we can isolate x and solve for your normal hourly rate.

its Frequency Distribution table
The answer is:
A frequency distribution for a collection of data is shown in the accompanying table.
The intervals or ranges of the data are displayed in the left column of the table, and the frequency or number of observations within each interval is displayed in the right column.
For instance, the first row demonstrates that 4 observations fall within the range of 10 to 19 while the second row demonstrates that 5 observations fall within the range of 20 to 29.
We only combine the frequencies to determine the total number of observations:
Total observations equal 25 (4 + 5 + 8 + 7 + 1 = 25)
By averaging the bottom and upper interval bounds, we can also determine each interval's midpoint. As an illustration, the first interval's midway (10-19) is as follows:
Midpoint: (14.5) (10 + 19) / 2
This may be done for each interval, and to display the midpoints, we can add a third column to the table.
The cumulative frequency, which is the overall frequency as we progress from the shortest interval to the longest interval, can then be calculated. The cumulative frequency can be displayed in the table by using a fourth column.
The finished table is shown here:
Interval Frequency Midpoint Cumulative Frequency
10-19 4 14.5 4
20-29 5 24.5 9
30-39 8 34.5 17

Find the exact solution to the equation. (5 points)
one hundred times one fifth to the power of quantity x divided by four equals four.
Answer:
x = 2
Step-by-step explanation:
We can start by rewriting the equation as follows:
100 * (1/5)^x / 4 = 4
Next, we'll multiply both sides by 4 to cancel out the division by 4:
400 * (1/5)^x = 16
Finally, we'll divide both sides by 400 * (1/5)^x to isolate (1/5)^x:
1/((1/5)^x) = 16 / 400 = 1/25
Taking the reciprocal of both sides:
(1/5)^x = 25
Taking the power of 5 to both sides:
x = log(25)/log(5) = 2
So x = 2 is the solution to the equation.

kari is buying aa batters and d batteries. the store sells aa batteries in packs of 6 and d batteries in packs of 10. if kari wishes to buy the same number of aa and d batteries, what is the smallest number of each battery type that she can buy
Kari can buy 30 AA batteries and 30 D batteries. We used simple LCM for this solution.
To find the smallest number of each battery type that Kari can buy, we must find the least common multiple (LCM) of 6 and 10. The LCM is the smallest multiple that both numbers can divide into evenly. To find the LCM, we can list the multiples of each number until we find a common multiple. In this case, the LCM of 6 and 10 is 30. So, Kari can buy 30 AA batteries and 30 D batteries, which gives her an equal number of both battery types.

The area of shape B is 312.5 cm²
Let us assume that the area of the shape B is m square units.
Here, the dimensions of shape A is 12 cm and the area of the shape A is 200 cm²
The dimensions of shape B is 15 cm and the area of the shape B is m cm²
Since A and B are two similar 2D shapes their dimensions must be in proportion.
So, we get an equation,
⇒ A² / B² = 200 / m
⇒ 12² / 15² = 200 / m
⇒ 144 / 225 = 200 / m

Mr. Ross is painting a wall that has an area of 142.5 square feet. He uses
3/4 gallon of paint to paint 1/5 of the wall.
How many gallons of paint will he need to paint the entire wall.
Answer:
Step-by-step explanation:
Say, in relation 3/4 gal of paint : 1/5 of wall. The decimal equivalent is 0.75 : 0.2. With this info., you can multiply 0.2 to get 1 which is equivalent to 1/5 X 5 to get 5/5. What you do to one side, you do to the other, so 0.75 X 5, which gives you 3.75 gal of paint. Round it to 4. So the final answer is 4 gal of paint.
3/4 : 1/5 -> 0.75 : 0.2 -> 5 x 0.75 : 0.2 x 5 -> 5 x 3/4 : 1/5 x 5
15/4 : 5/5 -> 3.75 : 1 = about 4 gals of paint b/c you can't just buy 3.75 gals of paint.
A family has a flower garden in the shape of a parallelogram in their backyard. They planted grass in the rest of the yard. What is the area of the backyard that is planted with grass?
Area of the backyard is 9000 sq.ft. Area of the flower garden is 60 sq.ft. So the area of backyard planted with grass will be 8940 sq.ft.
Here the backyard is in rectangular shape and the flower garden is a parallelogram.
Backyard has a length of 120ft and a width of 75ft. Area of a rectangle is given by the equation
Area of rectangle = length× width = 120×75 =9000 sq.ft
Area of backyard = 9000 sq.ft
The flower garden is a parallelogram with base 12 ft and height 5 ft.
Area of a parallelogram = Base× height = 12×5 = 60 sq.ft
Area of flower garden = 60 sq.ft
All the remaining area is planted with grass. So, the area of the portion of backyard planted with grass = Total area of backyard- area of the flower garden.
Area planted with grass = 9000-60 = 8940 sq.ft
So the area of the backyard is 9000 sq.ft, area of the flower garden is 60 sq.ft and area planted with grass is 8940 sq.ft.

Write the expression that is equivalent to (2x+5)(3x+1)
.
Answer & Step-by-step explanation:
To multiply these two binomials, we can use the distributive property as follows:
(2x+5)(3x+1) = 2x(3x+1) + 5(3x+1)
Now, we can simplify each term:
2x(3x+1) = 6x^2 + 2x
5(3x+1) = 15x + 5
Putting these back together, we get:
(2x+5)(3x+1) = 6x^2 + 2x + 15x + 5
Simplifying the middle two terms, we get:
(2x+5)(3x+1) = 6x^2 + 17x + 5
Therefore, the expression that is equivalent to (2x+5)(3x+1) is 6x^2 + 17x + 5.

The phrase "nominal number" is said to be quite new and rarely used. It seems to have come from the statistical phrase "nominal data," which is reportedly defined as data revealing "...merely declarations of qualitative category of membership," as it is used in school textbooks. The meaning of the word "nominal" in this use is "name."
Nominal numbering is mathematically a one-to-one and onto function from a set of named objects to a set of numbers, which may change (typically growing) over time. It is a function because each named object is assigned a single number; it is one-to-one because different objects are assigned different numbers; and it is onto because every number in the set at a given time has a single named object associated with it.
