a recipe uses 1 1/4 cups of milk to make 10 servings. if the same amount of milk is used for each serving, how many servings can be made using 1 gallon of milk? take 1 gallon to be equal to 16 cups. please show the work!
Answer:
128 servings can be made using 1 gallon of milk.
Step-by-step explanation:
Given that:
[tex]1\frac{1}{4}[/tex] cups of milk make 10 servings
[tex]1\frac{1}{4}[/tex] can also be written as 1.25
Ratio of cups of milk to servings = 1.25 : 10
1 gallon = 16 cups
Let,
x be the number of servings made from 1 gallon
Ratio of cups of milk to servings = 16 : x
This is a direct proportion
1.25 : 10 :: 16 : x
Product of mean = Product of extreme
10*16 = 1.25x
160 = 1.25x
1.25x=160
Dividing both sides by 1.25
[tex]\frac{1.25x}{1.25}=\frac{160}{1.25}\\x=128[/tex]
Hence,
128 servings can be made using 1 gallon of milk.

Answer/Step-by-step explanation:
1. m<MNQ = m<P + m<Q
Reason: exterior angle theorem of a triangle.
2. 132° = 3x + 54°
Reason: Substitution
3. x = 26
Reason: Algebra
Solving algebraically, x can be found as follows:
132° = 3x + 54°
132° - 54° = 3x (subtraction property of equality)
78° = 3x
78°/3 = 3x/3 (division property of equality)
26 = x
x = 26

Use the following situation to answer the next 2 questions: A manufacturer claims that a particular car will get at least 50 miles per gallon on the highway. The researchers of a consumer-oriented magazine believe this claim is too high and plan a test with a simple random sample of 30 cars. Assume the population standard deviation for individual cars is 2.3 miles per gallon. The researchers found the sample mean to be 49 miles per gallon, and they decided on using a = 0.05. (Hint: H n SD = H. Find the value of the test statistic. A.-2.38 B.-1.645 C.-0.43 D. 0.0087 E. 2.38 What is the conclusion of the hypothesis test? There evidence to reject the manufacturer's claim because sufficient:________A. Is not; 49 miles per gallon is too close to the claimed 50 miles per gallon B. Is not; the p-value of 0.0087 is less than the significance level C. Is; the sample mean is less than the claimed mean D. Is; the p-value of 0.0087 is less than the significance level E. Is; the p-value of 0.0174 is less than the significance level
Answer:
First question
The correct option is A
Second question
The correct option is E
Step-by-step explanation:
From the question we are told that
The population mean is [tex]\mu = 50 \ mpg \ (miles \ per \ gallon )[/tex]
The sample size is n = 30
The population standard deviation is [tex]\sigma = 2.3 \ miles[/tex]
The sample mean is [tex]\= x = 49 \ mpg[/tex]
The level of significance is [tex]\alpha = 0.05[/tex]
The null hypothesis is [tex]H_o : \mu = 50 \ mpg[/tex]
The alternative hypothesis is [tex]H_a : \mu < 50 \ mpg[/tex]
Generally the test statistics is mathematically represented as
[tex]t = \frac{ \= x - \mu }{ \frac{\sigma }{ \sqrt{n} } }[/tex]
=> [tex]t = \frac{ 49 - 50 }{ \frac{2.3}{ \sqrt{30 } } }[/tex]
=> [tex]t = -2.38[/tex]
Generally the degree of freedom is mathematically represented as
[tex]df = n - 1[/tex]
[tex]df = 30 - 1[/tex]
[tex]df = 29[/tex]
Generally from the student t distribution table the probability corresponding to -2.38 to the left at a degree of freedom of [tex]df = 29[/tex] is
[tex]p -value = P( t < -2.38 ) = 0.0174[/tex]
From the value obtained we see that
[tex]p-value < \alpha[/tex] hence
The decision rule
Reject the null hypothesis
The conclusion is
There evidence to reject the manufacturer's claim because the p-value of 0.0174 is less than the significance level E

A line passes through the point (-4, 7) and has a slope of -5/4
Write an equation in slope-intercept form for this line.
Answer:
We conclude that the equation in slope-intercept form for this line will be:
[tex]y\:=\:\frac{-5}{4}x+2[/tex]
Step-by-step explanation:
Given
The point = (-4, 7)slope = m = -5/4We know that the slope-intercept form of the line equation is
[tex]y=mx+b[/tex]
where m is the slope and b is the y-intercept
Using the slope-intercept form to find the y-intercept 'b'
substituting m = -5/4 and the point (-4, 7)
[tex]y = mx+b[/tex]
[tex]7=\:\frac{-5}{4}\left(-4\right)+b[/tex]
[tex]-\left(-5\right)+b=7[/tex]
[tex]5+b=7[/tex]
subtract 5 from both sides
[tex]5+b-5=7-5[/tex]
[tex]b=2[/tex]
now substituting b = 2 and m = -5/4 in the slope-intercept form
[tex]y = mx+b[/tex]
[tex]y\:=\:\frac{-5}{4}x+2[/tex]
Therefore, we conclude that the equation in slope-intercept form for this line will be:
[tex]y\:=\:\frac{-5}{4}x+2[/tex]

Answer:
[tex]9.8704 * 10^1[/tex]
Step-by-step explanation:
The standard form is called the scientific notation expressed generally as;
[tex]A * 10^n[/tex]
A is an integer between 1 and 10
n is ant integer or fraction
Given the decimal value 98.704, we ill shift the decimal point to the back once to have;
98.704 = [tex]9.8704 * 10^1[/tex]
Note the when the decimal point is shifted backwards the value of n is always positive. Hence the expansion in power of 10 is [tex]9.8704 * 10^1[/tex]

There are 28 rows in a corner section of a professional football stadium. Each row
contains 4 more seats than the row in front of it. If there are 15 seats in the first row, 19
seats in the second row, 23 seats in the third row, and so on, which equation represents
the number of seats “s”in the “nth” row?
A. s(n)= 11 +4n
B. s(n) = 15+41
С. s(n) = 28 + 4n
D. s(n) = 11n + 4
Answer: A. S(n) =11+4n
Step-by-step explanation:first row is 15 so 11+(1×4) and 11+(4×2)=19 and so onn.
One angle of an isosceles triangle measures 56°. Which other angles could be in that isosceles triangle? .
Answer:
68 or 62 degrees
Step-by-step explanation:
If the 56 degree angle is one of the base angles of the triangle, you can multiply it by two (because base angles of an isosceles triangle
are congruent), and then subtract 180 (because you must subtract the sum of two angles from 180 to get the measure of the third angle).
If the 56 degree is not a base angle, then you can use this equation to get the measurement of each base angle:
(180-56)÷2=measure of each base angle
180=sum of angle measures in a triangle
56=measure of third angle
With 180-56, you get the sum of the base angles, so you must divide by two. (Base angles of an isosceles triangle are congruent)
The other angles that could be in that isosceles triangle should be considered as the 56°, 68°, or 62°.
Calculation of the measurement of the angles:Since One angle of an isosceles triangle measures 56°.
So in the case when 56° angle is one of the two congruent angles, so the remaining angles are 56° and 180-2(56) = 68°
Now
In the case when the is 56° Is not congruent to either of the other angles, so each of the remaining two angles should be [tex](180-56)/2[/tex]= 62°.
hence, The other angles can be 56°, 68°, or 62°.

A medical researcher wishes to investigate the relationship between hours exercised and weight lost. The researcher randomly samples 50 people on an exercise program and asks them to report how many hours they have exercised on average over the last 6 weeks and how many pounds they have lost. The researcher runs a correlation and finds a test statistic of .34. Knowing that the critical value is .279, what should the researcher conclude
Answer:
The researcher will conclude that there is a correlation between the number of hours worked out and the amount of pounds lost by people on the exercise program
Step-by-step explanation:
Here, we want to state what the conclusion of the researcher should be:
From the last part of the question, we can see that the test statistic is greater than the critical value
So what do we do in a case like this?
We can see that the researcher is trying to see if there is a correlation between hours worked out and the number of pounds lost over a specific period of time.
Now, let us form the null hypothesis;
The null hypothesis here H0 is that we do not have a correlation between number of hours spent working out and the amount of pounds lost
The alternative hypothesis here H1 is that there is a correlation between the number of hours spent working out and the amount of pounds lost
Since we have the value of the test statistic greater than the critical value, we reject the null hypothesis and accept the alternative hypothesis
So therefore, the researcher will conclude that there is a correlation between the number of hours worked out and the amount of pounds lost by people on the exercise program
