If Frosty's Freeze sells 9 ounces of ice cream for $4.95, what is the cost per ounce of the ice cream?????

Answer: Answer is 193% or c

Step-by-step explanation: To solve this, we can use algebra. Suppose x represents the percent of increase. 1.37 * x = 4.02. Divide both sides by 1.37 to get x = 2.93. This represents 293% However, since it is asking for the increasing, we need to subtract 100% since we only want to increase, not the total value.

Answer:

b. 393%

Step-by-step explanation:

1.37 + 1.37x% = 4.02

Emmy answered average of 60 out of 75 math problems correctly on the quiz she took last week, meaning she answered a total of 60 problems correctly.

60/75 = 0.8

0.8 x 75 = 60

Emmy took a math quiz last week and answered 60% of the 75 problems correctly. To calculate how many problems Emmy got correct, we need to divide 60 by 75, which gives us 0.8. Then, we multiply 0.8 by 75, which gives us 60. This means that Emmy correctly answered 60 out of 75 math problems on the quiz. This is equivalent to 60%, which is the percentage of problems she got correct. It is important to note that if Emmy had answered any more or any less problems correctly, the percentage of correct answers would have been different. Therefore, it is important to understand the relationship between percentages and total number of problems answered correctly in order to accurately calculate the number of correct answers.

N[at least one club] = N[total ways] - N'[at least one club]

                               = N[total ways] - N[no clubs]

There are 39 cards without a club. So there are 39 choose 5 = 575757 ways to not get a club.

There are 2598960 possible hands, leaving us with 2598960-575757 ways.

Which is 2023203 hands.

How many 5 card hands will have (at least) two of the same number?

This is a standard deck. Take 2–10 to be what I mean by numbers.

N=∑k=24(91)(4k)⋅(125−k)(41)5−k+[(92)+(91)(41)](42)2⋅(111)(41)

+(91)(42)⋅(121)(43)+(91)(43)⋅(41)(42)

=(760,320+38,016+432)+114,048+2,592+864

=916,272

A standard deck of playing cards contains 13 unique ranks, each with 4 distinct suits. Since we are interested in only pairs from ranks 2 to 10, we shall define A be the collection of the 9 relevant ranks and B be the collection of the 4 ranks (ace, jack, queen, king) where pairs are not a consideration. Collection C is the union of A and B, which contains all 13 ranks.

When computing probabilities we need to select the ranks(s) from a collection and then choose a number of suits (cards). When ranks are chosen from either A or B they are also chosen from C. This is important since we might choose twice from the same collection. For example, we might choose a rank from A for a pair (9 choose 1) and later choose 3 ranks from C for singletons (12 choose 3).

To hopefully make understanding the logic easier, I have first chosen the ranks either from A, B, or C, and immediately following I have chosen the number of cards, which is always choosing from 4 suits. I have inserted a dot between different card selections.

We begin by computing the number of combinations with exactly 2, 3, and 4 of a kind from A. The singletons come from C.

N1=∑k=24(91)(4k)⋅(125−k)(41)5−k=760,320+38,016+432=798,768

We add the case of either two pairs from A or a pair from each of A and B. The singleton comes from C.

N2=[(92)+(91)(41)](42)2⋅(111)(41)=114,048

We add the case of a pair from A and 3 of a kind from C.

N3=(91)(42)⋅(121)(43)=2,592

Finally, we add the case of 3 of a kind from A and a pair from B. Note that the case of both 3 of a kind and a pair from A is the same as the case of both a pair and 3 of a kind from A, which has already been included.

N4=(91)(43)⋅(41)(42)=864

N=N1+N2+N3+N4=916,272

An arborist sights the top of a tree using a clinometer and reads the angle of elevation to be 29º, The height of the tree is 17.03 meters

Generally, To find the height of the tree, we can use the tangent function and some basic trigonometry. The tangent of an angle is the ratio of the opposite side (the height of the tree) to the adjacent side (the distance from the base of the tree to the clinometer).

tan(29) = opposite / adjacent

We know that the distance from the clinometer to the base of the tree is 28 meters, and that the clinometer is 1.5 meters above ground level.

So we can use the Pythagorean theorem to find the adjacent side:

adjacent = √(28^2 + 1.5^2)

= 28.03 meters

Now we can use the tangent function to find the opposite side:

opposite = tan(29) * adjacent

Using a calculator we can get the opposite = 15.53 meters

The height of the tree is opposite + 1.5 (the clinometer height) '

= 15.53 + 1.5

= 17.03 meters

Answer:

see explanation

Step-by-step explanation:

the equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

y = [tex]\frac{3}{4}[/tex] x - 1 ← is in slope- intercept form

with slope m = [tex]\frac{3}{4}[/tex]

• Parallel lines have equal slopes , then

y = [tex]\frac{3}{4}[/tex] x + c ← is the partial equation of the parallel line

to find c substitute (8, 4 ) into the partial equation

4 = [tex]\frac{3}{4}[/tex] (8) + c = 6 + c ( subtract 6 from both sides )

- 2 = c

y = [tex]\frac{3}{4}[/tex] x - 2 ← equation of parallel line

---------------------------------------------------------------

given a line with slope m then the slope of a line perpendicular to it is

[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{3}{4} }[/tex] = - [tex]\frac{4}{3}[/tex] , then

y = - [tex]\frac{4}{3}[/tex] x + c ← is the partial equation of the perpendicular line

to find c substitute (8, 4 ) into the partial equation

4 = - [tex]\frac{4}{3}[/tex] (8) + c = - [tex]\frac{32}{3}[/tex] + c ( add [tex]\frac{32}{3}[/tex] to both sides )

4 + [tex]\frac{32}{3}[/tex] = c , then

c = [tex]\frac{44}{3}[/tex]

y = - [tex]\frac{4}{3}[/tex] x + [tex]\frac{44}{3}[/tex] ← equation of perpendicular line

The probability that you pick exactly 2 juniors is 15/30 x 14/29 x 13/28 x 12/27, or 0.081.

1. Probability of picking the first junior: 15/30

2. Probability of picking the second junior: 14/29 (14 remaining juniors out of 29 total students after the first pick)

3. Probability of picking the third non-junior: 13/28 (13 remaining non-juniors out of 28 total students after the second pick)

4. Probability of picking the fourth non-junior: 12/27 (12 remaining non-juniors out of 27 total students after the third pick)

Therefore, the probability of picking exactly 2 juniors is

15/30 x 14/29 x 13/28 x 12/27

= 0.081.

The probability of picking exactly 2 juniors out of 4 slips of paper from a hat with the names of all 30 students in your statistics class is 0.081. This is calculated by taking the probability of picking the first junior (15/30) and multiplying it by the probability of picking the second junior (14/29, since there are 14 remaining juniors out of 29 total students after the first pick), the probability of picking the third non-junior (13/28, since there are 13 remaining non-juniors out of 28 total students after the second pick), and the probability of picking the fourth non-junior (12/27, since there are 12 remaining non-juniors out of 27 total students after the third pick).

Compound interest is the interest on a loan or deposit calculated based on both the initial principal and the accumulated interest from previous periods. It is the interest on interest, and it is the mechanism that causes an investment to grow at an exponential rate.

To calculate the amount of money you will have in the investment plan after 18 years, we can use the formula for compound interest:

A = P(1 + r)^n

Where:

A is the final amount (the future value)

P is the principal, or the initial deposit, in this case $300

r is the annual interest rate, in this case 7% (expressed as 0.07)

n is the number of years, in this case 18

m is the number of times the interest is compounded per year. in this case 12 (monthly)

By using this formula, the final amount will be:

A = 300(1 + 0.07/12)^(12*18)

A = $129,218.51

To compare this amount to the total deposits made over the time period, we can calculate the total amount of money deposited by multiplying the deposit amount ($300) by the number of deposits made per month (12) by the number of years (18).

Total deposit = 3001218 = $64,800

Hence, we have to pay $129,216.31; $64,800.

Case 17

y = x · (x + 6)

y = x² + 6 · x

y + 9 = x² + 6 · x + 9

y + 9 = (x + 3)²

Case 18

y = 3 · (x + 4) · (x - 8)

y = 3 · (x² - 4 · x - 32)

y + 3 · 4 = 3 · (x² - 4 · x + 4) - 3 · 32

y + 12 = 3 · (x - 2)² - 96

y + 108 = 3 · (x - 2)²

The approximate measure of angle JGH is 70.5°.

According to this question, we have a right triangle in which lengths of its hypotenuse (GH), in centimeters, and one leg (JH) are known and we must determine the measure of an angle (∠JGH), in degrees. A representation of this triangle is included in the image attached below.

By trigonometry we have the following expression for the required angle:

cos∠GJH = HJ/GH               .......(1)

Given, HJ = 2, GH = 6

cos∠GJH = 2/6

     ∠GJH = [tex]cos^{-1}\frac{2}{6}[/tex]

                ≈ 70.529

The approximate measure of angle JGH is 70.5°.
