There are 230 calories in 4 ounces of ice cream. How many calories are in 6 ounces of that ice cream?
Answers
Answer:
345 calories
Step-by-step explanation:
The easiest way to do this is to find out how many calories there are for 1 ounce. So 230 divided by 4, equals 57.5. So if 57.5 calories are in one ounce, then you just multiply by 6 to get your answer.
57.5 x 6 = 345 calories

Suppose 0 is an angle in the standard position whose terminal side is in
Quadrant IV and cos=12/37Find the exact values of the five remaining
37
trigonometric functions of 0
Answers
Answer:
Answers Below.
Step-by-step explanation:
Hello!
Let's first identifiy where the tereminals side actually is - Quadrant II. The original angle and the reference angle together form a straight line along the x-axis, so their sum is 180°. The second quadrant is in the upper left-hand corner of the plane. X has negative values in this quadrant and y has positive values. Quadrant III: The third quadrant is in the bottom left corner. Both x and y have negative values in this quadrant. The fourth quadrant (Q IV) is in the bottom right corner. X has positive values in this quadrant and y has negative values. Quadrant I of course has all positive values.
The five tig functions are:
Sine (sin)
Cosine (cos)
Tangent (tan)
Secant (sec)
Cosecant (csc)
Cotangent (cot)
The question asks for us to use the value of theta to find the rest of the trig values.
costheta=12/37 = 0.9999
Now, plug this number into the rest of them!
sin(0.9999)=0.01745
tan(0.9999)=0.01745
The last three are just reciporcals of the previous functions:
sec(x) = 1/ cosx = 1/cos(0.9999) = 1.0002
csc(x) = 1/ sinx = 1/sin(0.9999)= 57.304
cot(x) = 1/tanx = 1/tan(0.9999)= 57,296
The point of the unit circle is that it makes other parts of mathematics easier and neater. For instance, in the unit circle, for any angle θ, the trig values for sine and cosine are clearly nothing more than sin(θ) = y and cos(θ) = x.
Because the answers are in Quadrant IV, all the x values will be positive.
Hope this helps!

Answers
Answer:
8) 78.5 in.
11) 28.26 m
Step-by-step explanation:
The formula for area of a circle is πr^2 (pi ⋅ radius ⋅ radius).
Here, only the diameter is shown.
To find the radius, we must divide the diameter (10) by 2.
10/2 = 5.
So, 5 is the radius.
Now, we plug in the numbers.
pi ⋅ radius ⋅ radius
(3.14 is commonly used for pi)
3.14 ⋅ 5 ⋅ 5 = 78.5
78.5 is the area of this circle.
Now, to find the area of this circle, we simply repeat the steps.
6/2 = 3
pi ⋅ radius ⋅ radius
3.14 ⋅ 3 ⋅ 3 = 28.26

What type of quadrilateral is quadrilateral ABCD if AB=4x-2, BC=2x+12, DC=3x+5, AD=6x-16, AC=4x+12, DB=8x-10, and x=7? Explain and use the properties of the types of quadrilaterals as proofs.
Answers
Answer:
The quadrilateral ABCD is a square.
Step-by-step explanation:
According to the statement, AB, BC, CD and DA are the sides of the quadrilateral, whereas DB and AC are its diagonals. If we know that [tex]x = 7[/tex], [tex]AB = 4\cdot x - 2[/tex], [tex]BC = 2\cdot x + 12[/tex], [tex]DC = 3\cdot x +5[/tex], [tex]AD = 6\cdot x -16[/tex], [tex]AC = 4\cdot x + 12[/tex] and [tex]DB = 8\cdot x -10[/tex], the lengths of each line segment are respectively:
Sides
[tex]AB = 4\cdot (7) -2[/tex]
[tex]AB = 26[/tex]
[tex]BC = 2\cdot (7) +12[/tex]
[tex]BC = 26[/tex]
[tex]DC = 3\cdot (7) +5[/tex]
[tex]DC = 26[/tex]
[tex]AD = 6\cdot (7) -16[/tex]
[tex]AD = 26[/tex]
Diagonals
[tex]AC = 4\cdot (7) +12[/tex]
[tex]AC = 40[/tex]
[tex]DB = 8\cdot (7) - 10[/tex]
[tex]DB = 40[/tex]
This information indicates that this quadrilateral is a square because of these characteristics:
1) All sides have the same length.
2) The ratio of any diagonal to any side is [tex]\sqrt{2}[/tex].

A psychologist is interested in whether hypnosis affects brain dominance. Twelve college students from the freshmen class are randomly sampled for an experiment. The experiment has two conditions which are given on different days. In condition 1, the students are hypnotized and then given a test which measures the relative dominance of the right and left hemispheres. The higher the score, the more dominant is the right hemisphere. In condition 2, the same students are given the test again, only this time they are not hypnotized but are in their normal state of consciousness. The following scores are obtained:
Student 1 2 3 4 5 6 7 8 9 10 11
Condition 1 26 15 22 19 23 37 16 17 14 16 21
Condition 2 12 13 18 17 21 22 11 22 10 14 15
Answer the following questions and show your work for each mathematical question:

b. What is the null hypothesis?
c. What is the p value?
Answers
Answer:
[tex](a)\ H_a : d_1 - d_2 \ne 0[/tex]
[tex](b)\ H_0 : d_1 - d_2 = 0[/tex]
[tex](c)\ p\ value = 0.0216[/tex]
Step-by-step explanation:
Given
The above data
The question says 12 college students were sampled. However, data for 11 students were provided.
So, I will solve this question using 11 students i.e. n = 11
Solving (a): The alternative hypothesis
Let the relative dominance of the hypnotized students (condition 1) be [tex]d_1[/tex] and the relative dominance of the non-hypnotized students (condition 2) be [tex]d_2[/tex], respectively
The alternative hypothesis is the difference between these relative dominance not equal to 0.
So:
[tex]H_a : d_1 - d_2 \ne 0[/tex]
Solving (b): The null hypothesis
The null hypothesis is the difference between these relative dominance equal to 0.
Using the same notation as (a), the null hypothesis is:
[tex]H_0 = d_1 - d_2 = 0[/tex]
Solving (c): The p value
Using paired samples t test:
First, calculate the difference in scores
[tex]i.e.\ Condition\ 1 - Condition\ 2[/tex]
The difference (d) is as follows:
[tex]d: 14, 2, 4,2, 2, 15, 5, -5, 4, 2, 6[/tex]
Next, calculate the mean of the differences:
This is calculated as:
[tex]\mu = \frac{\sum x}{n}[/tex]
[tex]\mu = \frac{14+ 2+ 4+2+ 2+ 15+ 5 -5+ 4+ 2+ 6}{11}[/tex]
[tex]\mu = \frac{51}{11}[/tex]
[tex]\mu = 4.6364[/tex]
Next, calculate the standard difference of the differences.
This is calculated as:
[tex]\sigma = \sqrt{\frac{\sum(x - \mu)^2}{n-1}}[/tex]
So:
[tex]\sigma = \sqrt{\frac{(14 - 4.6364)^2+ (2- 4.6364)^2+ (4- 4.6364)^2+ ............ (6- 4.6364)^2}{11-1}}[/tex]
[tex]\sigma = \sqrt{\frac{318.54545456}{10}}[/tex]
[tex]\sigma = \sqrt{31.854545456}[/tex]
[tex]\sigma = 5.64398[/tex]
Next, calculate the standard error of the mean difference.
This is calculated as:
[tex]SE = \frac{\sigma}{\sqrt{n}}[/tex]
[tex]SE = \frac{5.64398}{\sqrt{11}}[/tex]
[tex]SE = \frac{5.64398}{3.3166}[/tex]
[tex]SE = 1.70173[/tex]
Next, calculate the degree of freedom (df)
[tex]df = n -1[/tex]
[tex]df = 11 -1[/tex]
[tex]df = 10[/tex]
Lastly, calculate the test statistics (t)
This is calculated as:
[tex]t = \frac{\mu}{SE}[/tex]
[tex]t = \frac{4.6364}{1.70173}[/tex]
[tex]t = 2.72452[/tex]
[tex]t \approx 2.72[/tex]
From the t distribution table:
Where [tex]df = 10[/tex] and [tex]t = 2.72[/tex]
We have:
[tex]P(t > 2.72) = 0.0108[/tex]
For a two-tailed test, the p value is
[tex]p\ value = 2 * P(t > 2.72)[/tex]
[tex]p\ value = 2 * 0.0108[/tex]
[tex]p\ value = 0.0216[/tex]

Answer:
659.52 cm^2
Step-by-step explanation:
In order to find the surface area of this figure, we need to know the dimensions of the base. If we assume the base is square, then the distance from its center to the center of one edge is half the dimension of one side of the base.
That center-to-edge distance (x) can be found from the given dimensions using the Pythagorean theorem.
x^2 + (15.4 cm)^2 = (17 cm)^2
x^2 = (289 -237.16) cm^2 = 51.84 cm^2
x = √51.84 cm = 7.2 cm
This means the edge length of the prism base is 2×7.2 cm = 14.4 cm.
__
The total surface area of the square prism is ...
A = b^2 +2bs . . . where b is the edge length of the base, s is the slant height
A = (14.4 cm)^2 + 2(14.4 cm)(17 cm) = 659.52 cm^2
The total surface area of this square pyramid is 659.52 cm^2.

The game of Scrabble has 100 tiles. The diagram shows the number of tiles for each letter and the letter's point value. One tile is drawn from Scrabble's 100 tiles. Find the probability of selecting an O or a V.
Answers
Answer:
10%
Step-by-step explanation:
In the image attached below, we can see that there are
8 tiles of letter O
2 tiles of letter V
This means that there are 10 total tiles of the letters that you want to get (O and V). Since there are a total of 100 tiles we need to divide this value by 100 to get the probability of getting one of these tiles.
10 / 100 = 0.10 or 10%
Finally, we can see that the probability of selecting a O or a V is 10%
Answer: 8% of O, 2% of V
Step-by-step explanation: There are 8 O tiles and 2 V tiles
