How to find the proportion of the whole?Proportion is defined a mathematical comparison between two numbers.
Now, we are given that:
Percentage of Ginger Ale = 35%
Percentage of Orange Juice = 25%
Percentage of Pineapple Juice = 25%
Percentage of Sorbet = 15%
We are told that there are 2 cups of Pineapple Juice. Thus:
(25/100) * x = 2
x = 200/25
x = 8 cups

Answer:
1) ΔCBA ~ ΔCQR
2) ΔCDE ~ ΔCTS
Step-by-step explanation:
In both cases, the vertical angles at C are congruent. The marking shows an additional internal angle is congruent, so the triangles are similar by the AA similarity postulate.
The vertex at C is named first, followed by the marked angle in each of the given similarity statements. The same order must be used for the vertices in the similar triangle.
1) ΔCBA ~ ΔCQR
2) ΔCDE ~ ΔCTS
the scale factor of two similar triangles prisms is 3:5. the volume of the larger prism is 175in^3. what is the volume of the smaller prism
The volume of the smaller prism is 37.8 in³. The result is obtained by using the ratio of corresponding volumes of two similar prisms.
How to find the volume of smaller prism with the scale factor?When two similar prisms or pyramids have a scale factor of L, the ratio of corresponding areas is L² and the ratio of corresponding volumes is L³.
The scale factor of two similar triangles prisms is 3 : 5. The volume of the larger prism is 175 in³. Find the volume of the smaller prism!
We have L = 3 : 5.
The ratio of corresponding volumes is
= L³
= (3/5)³
= 27/125
The smaller prism is
= (27/125) × 175 in³
= (27/5) × 7 in³
= 37.8 in³
Hence, the volume of the smaller triangles prisms is 37.8 in³.

Step 3 is unnecessary (the statement is already given, plus you haven't proven the triangle is isosceles anyway).
After, omit step 5 and jump straight to 6.
After this, step 6 is the statement that used to be step 5, which is true by CPCTC.
Then, you can prove the required statement by definition from this.
Use the expansion of (2-p)⁴ to find the coefficient of x² in the expansion of(1-4x+x²/2)⁴
To find the coefficient of x² in the expansion of (1-4x+x²/2)⁴, we can use the expansion of (2-p)⁴ and substitute p with (1-4x+x²/2).
The expansion of (2-p)⁴ is given by 1 - 8p + 24p² - 32p³ + 16p⁴. We can substitute p with (1-4x+x²/2) to get the expansion of (1-4x+x²/2)⁴. By replacing p with (1-4x+x²/2) in each term of the expansion, we obtain the following expression:
1 - 8(1-4x+x²/2) + 24(1-4x+x²/2)² - 32(1-4x+x²/2)³ + 16(1-4x+x²/2)⁴.
To find the coefficient of x², we need to identify the term that contains x². In this case, the term containing x² is 24(1-4x+x²/2)². Expanding this term further, we get: 24(1-8x+8x²/2-16x²+16x³/2+x⁴/4).
Simplifying this expression, we obtain: 24 - 192x + 96x² - 96x³ + 12x⁴.
Therefore, the coefficient of x² in the expansion of (1-4x+x²/2)⁴ is 96.

Question 6: Difference Quotient
Answer:
see explanation
Step-by-step explanation:
(a)
f(x) = 2x + 5 , then difference quotient is
\(\frac{2(x+h)+5-(2x+5)}{h}\)
= \(\frac{2x+2h+5-2x-5}{h}\)
= \(\frac{2h}{h}\)
= 2
(b)
f(x) = 3x² + x , then difference quotient is
\(\frac{3(x+h)^2+(x+h)-(3x^2+x)}{h}\)
= \(\frac{3(x^2+2hx+h^2+x+h-3x^2-x}{h}\)
= \(\frac{3x^2+6hx+3h^2+x+h-3x^2-x}{h}\)
= \(\frac{6hx+3h^2+h}{h}\)
= \(\frac{h(6x+3h+1)}{h}\)
= 6x+3h+1
Find two quadratic functions, one that opens upward and one that opens downward, whose graphs have the given x-intercepts. (-5,0), (5,0) opens upward f(x)=x²+x-5 X opens downward f(x)=x²-x+5
We have found two quadratic functions with x-intercepts (-5,0) and (5,0): f(x) =\(x^2 - 25\), which opens upward, and g(x) = \(-x^2 + 25\), which opens downward.
For the quadratic function that opens upward, we can use the x-intercepts (-5,0) and (5,0) to set up the equation:
f(x) = a(x + 5)(x - 5)
where a is a constant that determines the shape of the parabola. If this function opens upward, then a must be positive. Expanding the equation, we get:
f(x) = a(x^2 - 25)
To determine the value of a, we can use the fact that the coefficient of the x^2 term in a quadratic equation determines the shape of the parabola. Since we want the parabola to open upward, we need the coefficient of x^2 to be positive, so we can set a = 1:
f(x) = x^2 - 25
For the quadratic function that opens downward, we can use the x-intercepts (-5,0) and (5,0) to set up the equation:
g(x) = a(x + 5)(x - 5)
where a is a constant that determines the shape of the parabola. If this function opens downward, then a must be negative. Expanding the equation, we get:
g(x) = a(x^2 - 25)
To determine the value of a, we can use the fact that the coefficient of the x^2 term in a quadratic equation determines the shape of the parabola. Since we want the parabola to open downward, we need the coefficient of x^2 to be negative, so we can set a = -1:
g(x) = -x^2 + 25

you are in charge of conducting a very important study on the efficacy of imitrex on migraine sufferers. you ask 25 women to test this drug. each of the 25 women is given 'excedrin for migraines' immediately after the onset of their first migraine, after which you measure the time it takes for the headache to subside. after the onset of their second migraine, you give them imitrex and again measure the time it takes for the headache to subside. assuming the data are normally distributed, which is the most appropriate statistical test to determine if imitrex works better than excedrin at eliminating migraines?
If the p-value obtained from the paired t-test is less than the predetermined level of significance (usually 0.05), then it can be concluded that there is a statistically significant difference between the two treatments, and that imitrex is more effective than excedrin at eliminating migraines.
To determine if Imitrex works better than Excedrin at eliminating migraines in your study, the most appropriate statistical test to use is the Paired Samples t-test.
This test is suitable because:
We have two related samples: the same 25 women are given both Excedrin and Imitrex, so their response times are paired.
We're comparing the mean response times between two treatments, which requires a t-test.
The data is assumed to be normally distributed.
To conduct the Paired Samples t-test, follow these steps:
Calculate the difference in response times for each woman (Imitrex time - Excedrin time).
Calculate the mean of these differences.
Calculate the standard deviation of the differences.
Determine the degrees of freedom (25 women - 1 = 24).
Using the mean, standard deviation, and degrees of freedom, calculate the t-statistic.
Compare the t-statistic to the critical value from the t-distribution table, using your chosen significance level (e.g., 0.05).
If the t-statistic is greater than the critical value, reject the null hypothesis, concluding that there's a significant difference between the effectiveness of Imitrex and Excedrin for migraine relief.

You are measuring the time it takes for the headache to subside after administering each drug. To determine if Imitrex works better than Excedrin, the most appropriate statistical test to use would be a "paired t-test."
Step-by-step explanation:
1. Record the time it takes for the headache to subside after administering Excedrin and Imitrex to each woman.
2. Calculate the difference in time for each woman between the two drugs.
3. Compute the mean and standard deviation of these differences.
4. Perform a paired t-test to compare the mean difference to 0 (no difference between the two drugs).
5. Assess the p-value obtained from the t-test. If the p-value is less than the significance level (usually 0.05), then you can conclude that there is a statistically significant difference between the two drugs, suggesting that Imitrex works better than Excedrin in eliminating migraines.
