which is a unit rate? plis help :c
Answer:
6 hours : 1 book
Step-by-step explanation:
A unit rate is a rate with 1 in the denominator. If you have a rate, such as a price per some number of items, and the quantity in the denominator is not 1, you can calculate unit rate or price per unit by completing the division operation: numerator divided by denominator.

2. One action figure sells for $3.50 How many action figures can Sergio buy for $20.00?
Answer:
He can buy 5
Step-by-step explanation:
To find the answer, you have to do divide 3.50 and 20. You get 5.714285714. You can't round up, since you are dealing with money, so round down to 5.
Hope this helps :)
Step-by-step explanation:
One action figure can be shown as x so x=$3.50.
Sergio has $20.00 so the equation is 20.00÷3.50 = number of x's Sergio can buy.
20÷3.50 =5 2.5/3.5
So x=5 2.5/3.5

Which steps should be used to compare the fraction 2/9 and 5/8
Answer:
the last one
Step-by-step explanation:
You need make the same denominator
9 = 3*3
6 = 3*2
it follows that 3 *3 *2 is the simplest denominator
the fraction with the 6 needs to be multiplied by 3/3 and the one with 9 with 2/2

Step-by-step explanation:
Samantha just opened a new restaurant. She earned $550 on the first day and $750 on the third day that she was open for business. If Samantha's earnings continue to increase at the same rate, by how much are her earnings increasing each day? $________ per day Show your work. HINT: Find the slope.
Answer:
Step-by-step explanation:
If Samantha's earnings continue to increase at the same rate, this means that her earning is increasing arithmetically.
If she earned $550 in the first day, we can say the first term is $550
If she earned $750 on the third day, we can say the third term is $750
For us to know by how much her money is increasing, we need to find the common difference d formed by the sequence
550, x , 750
T1 = 550
T2 = x
T3 = 750
Common difference d = T2-T1 = T3-T2
x - 550 = 750 - x = d
Let's calculate the second term first i.e x
Since x - 550 = 750 - x = d
x - 550 = 750 - x
Collect like terms
x+x = 750+550
2x = 1300
x = 1300/2
x = 650
d = T2-T1
d = x - T1
d = 650-550
d = 100
Hence her money keeps increasing by $100 each day

Answer: The slope is 3/2 or 1.5
Step-by-step explanation:
The line is going through the origin meaning that the slope will be the coordinate of one of the points divided by its y coordinate.
One point that can be found on the line is (2,3)
Divide the y coordinate by the x coordinate to find the slope.
The y coordinate is 3 and the x coordinate is 2.
3/2 = 1.5
The slope is 3/2 or 1.5.
A scientist claims that 7% 7 % of viruses are airborne. If the scientist is accurate, what is the probability that the proportion of airborne viruses in a sample of 600 600 viruses would differ from the population proportion by greater than 3% 3 % ? Round your answer to four decimal places.
Answer:
The probability is [tex]P(|p-\^{p}| > 0.03) = 0.0040[/tex]
Step-by-step explanation:
From the question we are told that
The population proportion is [tex]p = 0.07[/tex]
The mean of the sampling distribution is [tex]\mu_p = 0.07[/tex]
The sample size is n = 600
Generally the standard deviation is mathematically represented as
[tex]\sigma_p = \sqrt{\frac{p (1 -p)}{n} }[/tex]
=> [tex]\sigma_p = \sqrt{\frac{0.07(1 -0.07)}{600} }[/tex]
=> [tex]\sigma_p = 0.010416 [/tex]
Generally the probability that the proportion of airborne viruses in a sample of 600 viruses would differ from the population proportion by greater than 3% is mathematically represented as
[tex]P(|p-\^{p}| > 0.03) = 1 - P(|p -\^{p}| \le 0.03)[/tex]
=> [tex]P(|p-\^{p}| > 0.03) = 1 - P(-0.03 \le p -\^{p} \le 0.03 )[/tex]
Now add p to both side of the inequality
=> [tex]P(|p-\^{p}| > 0.03) = 1 - P( 0.07-0.03 \le \^{p} \le 0.03+ 0.07 )[/tex]
=> [tex]P(|p-\^{p}| > 0.03) = 1 - P(0.04 \le \^{p} \le 0.10 )[/tex]
Now converting the probabilities to their respective standardized score
=> [tex]P(|p-\^{p}| > 0.03) = 1 - P(\frac{0.04 - 0.07}{0.010416} \le Z \le \frac{0.10 -0.07}{0.010416} )[/tex]
=> [tex]P(|p-\^{p}| > 0.03) = 1 - P(-2.88 \le Z \le 2.88 )[/tex]
=> [tex]P(|p-\^{p}| > 0.03) = 1 - [P(Z \le 2.88) - P(Z \le -2.88)][/tex]
From the z-table
[tex]P(Z \le 2.88) = 0.9980[/tex]
and
[tex]P(Z \le -2.88) = 0.0020[/tex]
So
[tex]P(|p-\^{p}| > 0.03) = 1 - [0.9980 - 0.0020][/tex]
=> [tex]P(|p-\^{p}| > 0.03) = 0.0040[/tex]

What is the combined weight of the bee and the pollen? Express your answer in scientific notation.
Answer:
0.18 g
Step-by-step explanation:
Weight of honeybee = [tex]1.2\times 10^{-1}\ \text{g}[/tex]
Weight of pollen = [tex]6\times 10^{-2}\ \text{g}[/tex]
The above values can be written in the following ways
[tex]1.2\times 10^{-1}\ \text{g}=0.12\ \text{g}[/tex]
[tex]6\times 10^{-2}\ \text{g}=0.06\ \text{g}[/tex]
Weight mass = [tex]0.12+0.06=0.18\ \text{g}[/tex]
The combined weight of the honeybee and the pollen is 0.18 g.

whats the difference between irrational and rational numbers
Answer:
difference between irrational and rational numbers:
Rational numbers: They are numbers which can be expressed in the form of p/q and q is not equal to 0
Examples: 3=3/1 , 0=0/1 , 17=17/1
Irrational Numbers: They are numbers which cannot be expressed in the form of p/q where q is not equal to 0
Example: Root 2, 1. 1517825278235............... , 45.87812254.............
this is the major difference between irrational and rational numbers.

Which equation represents a line which is parallel to the line 7x-5y=-30?
Answer:
Y=7/5x+8
Is the answer to question don't ask me how I know I cheated
The equation y = 7x/5 + b represents a line which is parallel to the line 7x-5y=-30.
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
We have an equation,
7x-5y=-30
Simplifying,
y = 7x/5 + 30/5
y = 7x/5 + 6.
The general formula of line parallel to a given line is,
y = 7x/5 + b, where b is the y-intercept of the line.
Therefore, y = 7x/5 + b is the required line.

There were 8 judges at a gymnastic competition. Kathleen received these scores for her performance on the uneven parallel bars: 8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2 Mean = 8.8 Median = 8.85 Mode = 8.9 Which statistic reflects a typical score? Explain.
Answer:
It is the MEAN
Step-by-step explanation:
Mean, median and mode given in the question are all used to measure central tendency of a given data. From the sets of data given, and from the values of the mean, median and mode (8.8, 8.85 and 8.9 respectively) it can be summarized that these values points the center of the sets of data trying to estimate the average.
MEAN is the statistic that reflects a typical score because when we look at the data (8.2, 8.7, 8.8, 8.8, 8.9, 8.9, 8.9, 9.2), it easily gives us the average score. Since mean = addition of the data value / the number of the data, it gives us Kathleen average score since it takes all the judges scores into consideration giving us the typical score. Unlike mode that only use most occured data meaning it doen't use all the data and as such may not show the true average of the scores. Also, mode is not consistent when it comes to small number of data especially if no score occur most or we have more than one mode. It is not median because of the small number of scores (data).

1/8k + 80= 1/2k + 120= ?
I need some help pls
1/8k + 80 = 1/2k + 120
Step 1: Subtract 1/2k from both sides.
1/8k + 80 - 1/2k = 1/2k + 120 - 1/2k
-3/8k + 80 = 120
Step 2: Subtract 80 from both sides.
-3/8k + 80 - 80 = 120 - 80
-3/8k = 40
Step 3: Multiply both sides by 8/(-3).
(8/-3) x (-3/8k) = (8/-3) x (40)
Answer: k = -320/3 or −106.667

Answer:

Step-by-step explanation:
I did this before
The mean absolute deviation of kai's test scores is 3.2.
What is mean absolute deviation?
The mean absolute deviation of a dataset is the average distance between each data point and the mean.
According to the given question
We have
the given data 92, 88, 90, 96, 84
For calculating mean absolute deviation
we will first calculate mean
mean = [tex]\frac{92+88+90+96+84}{5} =\frac{450}{5} = 90[/tex]
Now we will calculate the distance between each data point and the mean :
|92 -90| =2|88-90| =2|90-90| =0|96-90| = 6|84 -90| = 6Add the distances together
2+2+0+6+6 = 16
Divide the sum by number of data points.
MAD( mean absolute deviation ) = [tex]\frac{16}{5} =3.2[/tex]
Hence, the mean absolute deviation of Kai's test scores is 3.2.
