Answer 1

Answer:

a. R(t) = 2t - 500

b. D(t) = 400 + 10t

c. T(t) = 400 + 10t + 2t -500

Step-by-step explanation:

donations: $400; every person costs: $10; raffle ticket: $2; winner: $500

a. R(t) = 2t - 500

2t is the raffle tickets. t represents each person. -500 represents the money that the school loses for giving away the money to the winner.

b. D(t) = 400 + 10t

400 is the pre-donation that they had. 10t is the fee for entering the dinner per person. t represents each person.

c. T(t) represents all the money the school will gain (and lose) from the fundraiser. This stands to reason that T(t) is a combination of R(t) and D(t) since R(t) is the raffle and D(t) is the donations and dinner.

T(t) = 400 + 10t + 2t -500

Determine the unit rate: 2 dozen tennis balls for $36

Answers

Answer:

It is $1.50 or $18 per dozen tennis balls

Step-by-step explanation:

1. Divide the total price by the number of tennis balls.

36/24= 1.50

So it cost $1.50 per tennis ball.

2. Then solve by dividing the total price by the number of tennis balls:

36/2= $18

"So it cost $18 per dozen tennis balls"

It is $1.50 or $18 per dozen tennis balls

You must be in degree mode to find sin pie/3
A.) True
B.) False

Answers

Answer:

(i) False. Let A = 30° and B = 60°, then sin (A + B) = sin (30° + 60°) = sin 90° = 1 and, sin A + sin B = sin 30° + sin 60° = 1/2 + √3/2 = 1+√3/2(ii) True. sin 0° = 0 sin 30° = 1/2 sin 45° = 1/√2 sin 60° = √3/2 sin  90° = 1 Thus the value of sin θ increases as θ increases.(iii) False. cos 0° = 1 cos 30° = √3/2 cos 45° = 1/√2 cos 60° = 1/2 cos 90° = 0 Thus the value of cos θ decreases as θ increases.(iv) True. cot A = cos A/sin A cot 0° = cos 0°/sin 0° = 1/0 = undefined.

Step-by-step explanation:

False. You can use both degrees or radians to find sin(pi/3). You only HAVE to be in radians when working with circular objects(like the unit circle)

Can someone please help me? I've been trying to figure this out for days. I don't understand how to construct a confidence interval.

I know that the red box has a mean value of 15.11 and the blue box's mean is 16.83. The difference of sample means is 1.74. The red standard deviation is 3.868 and the blue one is 2.933. the standard deviation of the sample mean differences is 0.69. How do I use all this to construct the interval with no difference between the population means.

Answers

Step-by-step explanation:

Confidence interval is:

CI = x ± CV · SE

where x is the mean, CV is the critical value, and SE is the standard error.

There is no difference between the population means, so x = 0.

The confidence level is 95%, so CV = 1.96.

SE = 0.69.

So the confidence interval is:

CI = 0 ± (1.96) (0.69)

CI = (-1.35, 1.35)

1.74 is outside of the confidence interval, so it is statistically significant.

Fine the area of this figure round your answer to the nearest hundredth use 3.14 to approximate

Answers

Answer:    49.12 square feet

This value is approximate because we used the approximation pi = 3.14

=================================================

Explanation:

For problems like this, a common approach is to break the figure into smaller pieces. Find the area of each small piece, then add up those individual areas to get the full area we're after.

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

A = area of triangle

A = 0.5*base*height

A = 0.5*6*8

A = 24 square feet

-----------

B = area of the semicircle with radius r

B = 0.5*(area of full circle with radius r)

B = 0.5*(pi*r^2)

B = 0.5*pi*r^2

B = 0.5*3.14*4^2 .... the diameter is 8, radius is half that

B = 25.12  square feet

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

C = area of the full figure

C = A+B

C = 24+25.12

C = 49.12 square feet

Find the z-score such that: a. The area under the standard normal curve to its left is 0.5 b. The area under the standard normal curve to its left is 0.9826 c. The area under the standard normal curve to its right is 0.1423 z

Answers

Answer:

The answer is below

Step-by-step explanation:

The z score is used to determine by how many standard deviations the mean is above or below the raw score. If the z score is positive then the raw score is above the mean while if the z score is negative then the raw score is below the mean. The z score is given by:

[tex]z=\frac{x-\mu}{\sigma}\\ \\\mu=mean, \sigma=standard\ deviation[/tex]

a)

From the normal distribution, 0.5 corresponds to a z score of 0.

z = 0.

b) From the normal distribution, an area of 0.9826 to the left corresponds to a z score of 2.11.

c) An area to the right of 0.1423 = an area of 0.8577 ( 1- 0.1423) to the left.  From the normal distribution, an area of 0.8577 to the left corresponds to a z score of 1.07

Steve has 54 stamps in his collection of 13 cent, 29 cent, and 45 cent stamps, totaling a value of $15.98. If the number of 13 cent stamps is doubled, the new total value of his stamp collection would be $17.80. Find the number of each type of stamp in his collection.

Answers

Answer:

Number of 13 cents stamp = 14

Number of 29 cents stamp = 24

Number of 45 cents stamp = 16

Step-by-step explanation:

We are told he has 54 stamps in total.

These stamps are;13 cent, 29 cent, and 45 cent stamps.

Let's call number of 13 cent($0.13) stamp A

Call number of 29 cent($0.29) stamp B

Call number of 45 cent($0.45) stamp C

Thus;

A + B + C = 54

We are told the total value of the 3 stamps are $15.98.

Thus;

0.13A + 0.29B + 0.45C = $15.98 - - - (eq2)

Now we are told that if the number of 13 cent stamps is doubled, the new total value of his stamp collection would be $17.80.

Thus;

2(0.13A) + 0.29B + 0.45C = 17.8

0.26A + 0.29B + 0.45C = 17.8 - - - (eq 3)

Solving the 3 equations simultaneously, we have;

A = 14

B = 24

C = 16

We have;

Number of 13 cents stamp = 14

Number of 29 cents stamp = 24

Number of 45 cents stamp = 16

1.If x and y vary directly and y = 16 when x = 12, then which of the following equations correctly represents the relationship between x and y?

Answers

Answer:

[tex]y = \frac{4}{3}x[/tex]

Step-by-step explanation:

Given:

Variation: Direct Variation.

This can be represented as:

[tex]y\ \alpha\ x[/tex]

[tex]y = 16; x = 12[/tex]

Required

Write out the equation

First, the variation has to be converted to an equation

[tex]y\ \alpha\ x[/tex]

[tex]y = kx[/tex]

Where k represents constant of variation.

Substitute 16 for y and 12 for x

[tex]16 = k * 12[/tex]

Solve for k

[tex]k = \frac{16}{12}[/tex]

[tex]k = \frac{4}{3}[/tex]

To get the equation, we simply substitute 4/3 for k in [tex]y = kx[/tex]

[tex]y = \frac{4}{3}x[/tex]

Which of the original 13 colonies did English settle please help with this question ty Pls need help ASAP i need done before 11:59 I NEED HELP QUICK I FORGOT WHEN IT WAS DUE AND ITS DUE TODAYFROGS AND TADPOLESIt is very interesting in the spring to watch the gradual development of a frog from the egg, through the tadpole stage of its existence, till at last it assumes its final form. The old frogs emerge from their winter hiding-places in the mud, early in the spring, and during April their eggs may be found floating on almost every stagnant pond. A group of these eggs in their early stages of development looks like a mass of clear white jelly, containing numbers of black specks, each of which is really the germ of the future tadpole. In order to watch the development, a group of the eggs should be taken and put in a shallow vessel of water, which, if kept in the house, should have a bell-glass, or some other covering, over it, to keep out the dust. The jelly-like mass which envelopes the future tadpole is so clear that all its changes can be easily watched. First the head appears, then a flat tail, and in course of time the nostrils, mouth and large eyes, till at length the completed tadpole bursts open its gelatinous covering, and apparently not in the least embarrassed by its new surroundings, begins swimming briskly about, looking for something to eat. The time occupied in hatching varies in different countries, according to the climate, from four days to a month. The following stages are even more interesting, especially for those who can take advantage of the transparency of the parts to watch the circulation of the blood through a microscope. The body of the tadpole gradually gets broader, while the tail gets thinner and thinner, till it finally disappears altogether. However, before that happens, its place has been taken by two hind legs, which first appear under the skin and then gradually push their way through. The fore legs next appear, and so on through all the stages of development, till in a longer or shorter time, according to the amount of warmth, light and food it can obtain, the complete frog appears. But woe betide the unfortunate tadpole which, first of the shoal, attains to the dignity of possessing limbs, for so ferocious are the later ones, and so jealous of their precocious little brother, that they almost always fall upon him, and not content with killing, never rest till every morsel of him is eaten. And unless several of the tadpoles assume their final change about the same time, this proceeding is repeated till their numbers are very considerably diminished, or, as sometimes happens, till only one survivor is left, who, having helped to eat all his brethren, is allowed to live on in peace. Of course, this is only till some day, in the course of his walks abroad, he, in his turn, is snapped up as a delicate morsel by some hungry snake or water-fowl.
