A recipe calls for 3/5 gallon of milk. how much milk is needed to make half the recipe
Answers
Answer:
3/10 gallons
Step-by-step explanation:
We know that the recipe for 1 serving calls for 3/5 gallons of milk.
We want to know what 1/2 a serving calls for. Let's set up a proportion:
(1/2) / 1 = x / (3/5) , where x is the amount of milk needed for 1/2 the recipe
Cross-multiply:
x * 1 = (1/2) * (3/5)
x = 3/10
The answer is thus 3/10 gallons.

Answer:
3/10 gallon of milk
Step-by-step explanation:
The recipe needs 3/5 gallon of milk, half of the recipe requires half of the milk.
3/5 half is:
[tex]3/5 \times 1/2[/tex]
[tex]=3/10[/tex]
What is the answer? x^2-y^2=55
Answers
Answer:
To solve for x we can write:
x² - y² = 55
x² = y² + 55
x = ±√(y² + 55)
To solve for y:
x² - y² = 55
y² = x² - 55
y = ±√(x² - 55)
how much money do you earn in 1 hour if you earn 20 in 4 hours
Answers
Answer:
let’s make a Unit rate.
$20/4 hours = $5 per hour
So you earn $5 in 1 hour if you earn $20 in 4 hours.
hope this helps and pls mark me brainliest if it did ;)
Answer:
$5
Step-by-step explanation:
Let's set up a proportion using the following setup.
money/hours=money/hours
We know that $20 is earned in 4 hours. We don't know how much is earned in 1 hour, so we can say $x is earned in 1 hour.
$20/4 hours= $x/1 hour
20/4=x/1
x/1 is equal to x.
20/4=x
Divide 20 by 4.
5=x
$5 is earned in 1 hour.
paulina plays both volleyball and soccer .the probability of her getting injured playing soccer is 0.10 and the probability of her getting injured playing soccer is 0.20 .which of the event is more likely
Answers
Step-by-step explanation:
While playing volleyball, probability of getting hurt is
P(A) = 0.1 = 1/10
and in the case of soccer, it is
P(B) = 0.2 = 2/10 = 1/5
Here we see, P(A) < P(B)
Answer: We can conclude that the probability of getting injured while playing soccer is more likely.

If
f(x) = 13x + 1, then
f-1(x) =
Answers
Answer:
(x-1)/13
Step-by-step explanation:
y = 13x+1
To find the inverse, exchange x and y
x = 13y+1
Solve for y
Subtract 1 from each side
x-1 =13y+1-1
x-1 = 13y
Divide each side by 13
(x-1)/13 = y
The inverse is (x-1)/13
Answer:
f(x) = 13x + 1
To find the inverse let f(x) = y
y = 13x + 1
x = 13y + 1
13y = x - 1
y = (x-1)/13
The inverse is x-1/13.

Complete Question is;
Which values of a and b make the following equation true (5x^7 • y²) * (-4x⁴ • y^5) = -20x^a • y^b
Answer:
Option A - a = 11 and b = 7
Step-by-step explanation:
We are given the equation as;
(5x^7 • y²) * (-4x⁴ • y^5) = -20x^a • y^b
In algebra, we know that, zⁿ × z² = z^(n + 2).
Thus, collecting like terms in powers on left hand side, we have;
-20(x^(7 + 4)) × (y^(2 + 5)) = -20x^a • y^b
-20(x^(11))•(y^(7)) = -20x^a • y^b
Comparing the left and right hand side, we have;

The measures of two angles of a triangle are 105 and 31 degrees. Find the measure of the third angle.
Answers
Answer: 44°
Step-by-step explanation:
Measures of the angles of a triangle
= 180°
Therefore, 180 - 105 + 31 = 44°
The measure of the third angle is 44 degrees.
We have,
To find the measure of the third angle in a triangle, we can use the fact that the sum of the measures of all three angles in a triangle is always 180 degrees.
Let's denote the measure of the third angle as "x".
We are given that the measures of the other two angles are 105 degrees and 31 degrees.
Using the sum of angles in a triangle, we can set up the equation:
105 + 31 + x = 180
Simplifying the equation:
136 + x = 180
To isolate "x", we subtract 136 from both sides of the equation:
x = 180 - 136
x = 44
Therefore,
The measure of the third angle is 44 degrees.

A simple random sample of 5 months of sales data provided the following information: Month: 1 2 3 4 5 Units Sold: 94 105 85 94 92 (a) Develop a point estimate of the population mean number of units sold per month. x = (b) Develop a point estimate of the population standard deviation. If required, round your answer to two decimal places. s =
Answers
Answer:
a) x = 94 units/month
b) s = 51.50 units/month
Step-by-step explanation:
The adequate point estimation of the population mean and standard deviation are the sample mean and sample standard deviation.
a) Point estimation of the population (sample mean)
[tex]M=\dfrac{1}{n}\sum_{i=1}^n\,x_i\\\\\\M=\dfrac{1}{5}(94+105+85+94+92)\\\\\\M=\dfrac{470}{5}\\\\\\M=94\\\\\\[/tex]
b) Point estimation of the population standard deviation (sample standard deviation)
[tex]s=\dfrac{1}{n-1}\sum_{i=1}^n\,(x_i-M)^2\\\\\\s=\dfrac{1}{4}((94-94)^2+(105-94)^2+(85-94)^2+(94-94)^2+(92-94)^2)\\\\\\s=\dfrac{206}{4}\\\\\\s=51.50\\\\\\[/tex]
Using statistical concepts, it is found that:
a) The point estimate for the population mean is of: [tex]\overline{x} = 94[/tex]
b) The point estimate for the population standard deviation is of: [tex]s = 7.18[/tex]
Item a:
The mean of a data-set is the sum of all observations in the data-set divided by the number of observations.The point estimate for the population mean is the sample mean.In this problem, the sample is: 94, 105, 85, 94, 92.
Thus, the mean is:
[tex]\overline{x} = \frac{94 + 105 + 85 + 94 + 92}{5} = 94[/tex]
Item b:
The standard deviation of a data-set is the square root of the sum of the differences squared between each observation and the mean, divided by one less than the number of values.The point estimate for the population standard deviation is the sample standard deviation.Then:
[tex]s = \sqrt{\frac{(94-94)^2+(105-94)^2+(85-94)^2+(94-94)^2+(92-94)^2}{4}} = 7.18[/tex]

Suppose tossing a coin 8 times represents the 8 cups of tea, heads represents a correct identification of what was poured first, tea or milk, and tails represents an incorrect identification of what was poured first. Select the best conclusion you would draw about whether the woman was just guessing.
A. Repeat the process many times (1000). If 6 correct out of 8 cups rarely occurs, then it is most likely that the woman was just guessing as to what was poured first.
B. Repeat the process many times (1000). If 8 correct out of 8 cups rarely occurs, then it is unlikely that the woman was just guessing as to what was poured first.
C. Repeat the process many times (1000). If 8 correct out of 8 cups rarely occurs, then it is likely that the woman was just guessing as to what was poured first.
D. Repeat the process many times (1000). If 4 correct out of 8 cups rarely occurs, then it is unlikely that the woman was just guessing as to what was poured first.
Answers
Answer:
A. Repeat the process many times (1000). If 6 correct out of 8 cups rarely occurs, then it is most likely that the woman was just guessing as to what was poured first.
Step-by-step explanation:
Since tossing a coin 8 times implies 8 cups of tea, with the given conditions.
The sample space = 1000
Then;
[tex]\frac{6}{8}[/tex] × 1000 = 750
If 6 correct out of 8 cups occurs (750 out of 1000), the woman got 750 correctly. Thus it can be inferred that it is likely that she knew what was poured first, either the tea or milk.
But, if 6 correct out of 8 cups rarely occurs (i.e 250 out of 1000), then it is most likely that the woman was just guessing as to what was poured first.
Assume that the population proportion is 0.56. Compute the standard error of the proportion, σp, for sample sizes of 100, 200, 500, and 1,000. (Round your answers to four decimal places.)
Answers
Answer:
Standard errors are 0.049, 0.035, 0.022, and 0.016.
Step-by-step explanation:
The given value of population proportion (P) = 0.56
Given sample sizes (n ) 100, 200, 500, and 1000.
Now standard error is required to calculate.
Use the below formula to find standard error.
When sample size is n = 100
[tex]\sqrt{\frac{P(1-P)}{n}} = \sqrt{\frac{0.56(1-0.56)}{100}} =0.049[/tex]
When sample size is n = 200
[tex]\sqrt{\frac{P(1-P)}{n}} = \sqrt{\frac{0.56(1-0.56)}{200}} = 0.035[/tex]
When sample size is n = 500
[tex]\sqrt{\frac{P(1-P)}{n}} = \sqrt{\frac{0.56(1-0.56)}{500}} =0.022[/tex]
When sample size is n = 1000
[tex]\sqrt{\frac{P(1-P)}{n}} = \sqrt{\frac{0.56(1-0.56)}{1000}} = 0.016[/tex]
You perform a random experiment by rolling one time two fair six-sided dice and record the number of each die. Define and/or give examples of the following:
a. Give an example for a single outcome of your experiment?
b. What is the sample space of your experiment?
c. What is the probability for the first die to be two?
d. What is the probability that the value rolled on die 1 minus the value rolled on die 2 is positive?
Answers
Answer:
(c)1/6
(d)5/12
Step-by-step explanation:
When two fair six-sided dice are rolled once
(a)The pair (x,y) denotes a single outcome of the experiment where x is the outcome of the first die and y is the outcome of the second die.
For example, (2,1) means the first die shows a 2 while the second die shows an outcome of 1.
(b)Sample Space
The sample space of all possible outcome is:
[tex](1, 1), (1, 2), (1, 3), (1, 4), (1, 5), (1, 6)\\(2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)\\(3, 1), (3, 2), (3, 3), (3, 4), (3, 5), (3, 6)\\(4, 1), (4, 2), (4, 3), (4, 4), (4, 5), (4, 6)\\(5, 1), (5, 2), (5, 3), (5, 4), (5, 5),(5,6)\\(6, 1), (6, 2), (6, 3), (6, 4), (6,5), (6,6)[/tex]
Total Number of Outcomes =36
(c)The probability for the first die to be two
The outcomes where the fist die is 2 are:
[tex](2, 1), (2, 2), (2, 3), (2, 4), (2, 5), (2, 6)[/tex]
Therefore:
The probability for the first die is two
[tex]=\dfrac{6}{36}\\\\=\dfrac{1}{6}[/tex]
(d)The probability that the value rolled on die 1 minus the value rolled on die 2 is positive
These are the outcomes of the pair (x,y) where x>y.
They are:
[tex](2, 1)\\(3, 1), (3, 2)\\(4, 1), (4, 2), (4, 3)\\(5, 1), (5, 2), (5, 3), (5, 4)\\(6, 1), (6, 2), (6, 3), (6, 4), (6,5)[/tex]
