Work out and simplify where possible. A) 3/4 + 5/6. B) 4/7 - 1/3

Answers

Answer 1
A) To add 3/4 and 5/6, we need to find a common denominator. The least common multiple of 4 and 6 is 12. We can convert 3/4 to 9/12 by multiplying the numerator and denominator by 3. Similarly, we can convert 5/6 to 10/12 by multiplying the numerator and denominator by 2. Now we have a common denominator of 12, so we can add the fractions:

3/4 + 5/6 = 9/12 + 10/12 = (9 + 10)/12 = 19/12

B) To subtract 1/3 from 4/7, we also need a common denominator. The least common multiple of 3 and 7 is 21. We can convert both fractions to have a denominator of 21:

4/7 = (4/7) * (3/3) = 12/21

1/3 = (1/3) * (7/7) = 7/21

Now we can subtract the fractions:

4/7 - 1/3 = 12/21 - 7/21 = 5/21

A restaurant manager recorded the number of people in different age groups who attended their food festival. They created the following histogram:

Histogram with title Food Festival Participants, horizontal axis labeled Age Group (year) with bins 0 to 19, 20 to 39, 40 to 59, and 60 to 79, and vertical axis labeled Number of People with values from 0 to 60 at intervals of 10. The first bin goes to 20, the second goes to 40, the third goes to 60, and the last goes to 50.

What percentage of the participants are ages 40 to 59? Round to the nearest whole percent.

Answers

Looking at the histogram, we can see that the age group 40 to 59 has a frequency of 30 people. The total number of participants can be found by adding up all the frequencies, which is 20 + 40 + 60 + 50 = 170 people.

To find the percentage of participants that are ages 40 to 59, we can use the following formula:

percentage = (frequency / total number of participants) x 100%

Substituting the values we found, we get:

percentage = (30 / 170) x 100% ≈ 17.6%

Rounding to the nearest whole percent, we get that approximately 18% of the participants are ages 40 to 59.

Answers

Answer:The algebraic steps you have taken are incorrect, leading to an invalid conclusion. Let's go through each step and see where the mistake is made:

X = 1 (given)

X+X = 1+X (adding X to both sides)

2X = 1+X (combining like terms)

2X = X+1 (rearranging terms)

2X-2 = X+1-2 (subtracting 2 from both sides)

2X-2 = X-1 (simplifying)

2(x-1)/(x-1) = (x-1)/(x-1) (dividing both sides by x-1, note that x cannot be 1 as it would result in division by 0)

2 = 1 (canceling out the (x-1)/(x-1) on both sides)

The error lies in dividing both sides by (x-1) in step 7. Although (x-1) appears on both sides of the equation, it is not equal to zero as x cannot be 1 due to division by zero. Dividing by (x-1) effectively cancels it out, leading to the incorrect result of 2=1.

A motorboat travels 234 miles in 6 hours going upstream. It travels 342 miles going downstream in the same amount of time. What is the rate of the boat in still water and what is the rate of the current

Answers

The boat is moving at 48 mph while the current is moving at 9 mph in still water.

To solve this problem

Let's use the letters "B" for the boat's speed in still water and "C" for the current's speed.

The boat's effective speed upstream is B - C because it is moving against the current.

Since the boat is moving downstream against the tide, its effective speed is equal to B plus C.

Based on the supplied data, we can construct the following two equations:

234 = 6(B - C)

342 = 6(B + C)

Making these equations simpler:

39 = B - C

57 = B + C

Now that we have added the two equations, we may solve for B and C:

39 + 57 = 2B

96 = 2B

B = 48

Therefore, the boat's speed in calm water is 48 mph.

To find C, we can rewrite one of the initial equations with this value as a substitute:

39 = 48 - C C = 9

Thus, the current is moving at a 9 mph velocity.

Therefore, the boat is moving at 48 mph while the current is moving at 9 mph in still water.

Answers

The explicit rule for the sequence 4, 3 2/3, 3 1/3, 3.... is f(n) = 4 - 1/3(n - 1)

Finding the explicit rule for the sequence

From the question, we have the following parameters that can be used in our computation:

4, 3 2/3, 3 1/3, 3....

In the above sequence, we can see that 1/2 is subtracted from the previous term to get the new term

Take for instance

2nd = 4 - 1/3 = 3 2/3

3rd = 3 2/3 - 1/3 = 3 1/3

4th = 3 1/3 - 1/3 = 3

And so on

This means that

First term, a = 4Common difference, d = -1/3

So, the explicit rule is

f(n) = a + (n - 1)d

This gives

f(n) = 4 - 1/3(n - 1)

Hence, the explicit formula is f(n) = 4 - 1/3(n - 1)

An equation for the height of the rocket after t seconds is h(t) = -16t² + 352t.

The time it takes for the rocket to reach a height of 0 is 22 seconds.

The time it takes to reach the top of its trajectory is 11 seconds.

The maximum height is 1,936 feet.

The time it takes to reach a height of 968 feet is 18.8 or 3.2 seconds.

How to determine the time when the rocket would hit the ground?

Based on the information provided, we can logically deduce that the height (h) in feet, of this rocket above the​ ground is related to time by the following quadratic function:

h(t) = -16t² + Vit

When the initial velocity is 352 feet per seconds, the height function becomes;

h(t) = -16t² + 352t

Generally speaking, the height of this rocket would be equal to zero (0) when it hits the ground. Therefore, we would equate the height function to zero (0) as follows:

0 = -16t² + 352t

352t = 16t²

Time, t = 352/16

Time, t = 22 seconds.

Next, we would determine the maximum height of this rocket by taking the first derivate in order to determine the time (t) it takes;

h(t) = -16t² + 352t

h'(t) = -32t + 352

352 = 32t

t = 352/32 = 11 seconds.

h(11) = -16(11)² + 352(11)

h(11) = 1,936 feet.

At a height of 968 feet, the time is given by;

968 = -16t² + 352t

16t² - 352t + 968 = 0

t² - 22t + 60.5 = 0

Time, t = 18.8 or 3.2 seconds.

What is an inverse function ?

If the inverse function of f is the function g, then x = f(x) gives x = g(y). We just need to reverse the function.

An inverse function or an anti function is defined as a function, which can reverse into another function. In simple words, if any function “f” takes x to y then, the inverse of “f” will take y to x. If the function is denoted by ‘f’ or ‘F’, then the inverse function is denoted by f-1 or F-1. One should not confuse (-1) with exponent or reciprocal here.

If f and g are inverse functions, then f(x) = y if and only if g(y) = x

The function is :

[tex]f(x) =\frac{-1}{25x^{2} },x < 0[/tex]

We have to find the inverse of the function.

The inverse, interchange the variables solve for y,

Now,

[tex]f(x) =\frac{-1}{25x^{2} },x < 0[/tex]

Answers

Note that the probabilities are given below.


What are the probabilities?

a) the probability of a randomly selected catch being a mouse caught by Cyd

p(Catching a mount) x p(Cyd made the catch)

= 0.5x .2

= 0.1

b) the   probability of a bird not caught by Cyd is 0.5 x 0.8 = 0.4.

Thus

P(that a catch is a bird) x p(the Cyd didn't make the catch)

= 0.3 x 0.8

=0.24

c) The probability of a randomly selected catch being caught by Greg is 0.45

To calculate, we say

(0.5   x0.45) + (0.3 x 0.45) + (0.2 x .45)

= 0.45.

d)

P (mouse caught by Greg) = (0.45 x 0.5) / 1

= 0.225.

e) P(catch is a mouse caught by Ken and catch is a mouse)

= P(catch is a mouse | catch is made by Ken) x P(catch is made by Ken)

= 0.05 x 0.1

Answers

The minimum number of people over age 30 they must include in their sample is: 829 people

How to calculate the standard error?

The formula for calculating the standard error is:

SE = μ ± Z(σ/√N)

Where:

σ = the standard deviation,

N = the sample size,

Z = the Z value for the percent confidence level desired.

We must find the Z value, at the 85% confidence level from a Cumulative Standardized Normal table for the 99% confidence level. This gives us the value of Z = 1.44

σ = 1.4 liters

N = 0.07

Thus:

0.07 = 1.44(1.4/√N)

0.07/1.44 = 1.4/√N

Factor cards is a one - player game using numbered cards. To begin with, all cards are in a central pile with their numbers visible. At each turn , exactly one card is moved from the central pile to the score pile and one or more cards are moved from central pile to the discard pile according to these rules.
Rule 1: A card may be moved to the score pile only if the number on the card has at least one of its factors, other than itself, still on the central pile.
Rule 2: When a card is moved to the score pile, all the cards that have factors of its number and are still in the central pile are moved to the discard pile.
Play stops when no card in the control pile has a factor other than itself in the central pile. The players score is the sum of all numbers on the cards in the score pile at the end of play.
In the following questions, the game starts with 20 cards numbered 1 to 20 and are therefore called 20-games.
A) Show steps that will produce a score of more than 100 points in a 20- game
B) What is the maximum score for a 20- game. Explain why it is the maximum
C) Explain why every 20- game ends with 8 or fewer cards in the score pile .

Answers

The match terminates as soon as the central heap runs out of cards whose factor are not present elsewhere, resulting in a score of 92 - falling short from 100.

How to explain the information

It should be noted that to acquire a higher point achievement, alternative approaches can be tested; however, reaching beyond the hundred mark is not guaranteed.

Conversely, with each 20-game, the final outcome should contain 8 or fewer pieces in the tally pile since there are strictly 17 cards eligible to be shifted into this collection. Subsequently, due to the 138 maximum points potential (stated in part B), and the entire set amounting for 210 points - the minimum count for items within the discard pool will be 3 (as calculated from 20 - 17).

What are the trigonometric ratios?

The three trigonometric ratios are the sine, the cosine and the tangent, and they are defined as follows:

Sine of angle = length of opposite side to the angle divided by the length of the hypotenuse.Cosine of angle = length of adjacent side to the angle divided by the length of the hypotenuse.Tangent of angle = length of opposite side to the angle divided by the length of the adjacent side to the angle.

The sum of the internal angle measures of a triangle is of 180º, hence the missing angle is given as follows:

m < L = 180 - (30 + 60)

m < L = 90º.

Hence the segment JL represents the hypotenuse of the figure.

JL is opposite to the angle K, hence it's length is obtained as follows:

sin(30º) = JL/26

1/2 = JL/26

2JL = 26

JL = 13.

Segment KL is adjacent to the angle of 30º, hence it's length is obtained as follows:

10 ft

Answers

The height will be  61.8 ft

How to solve for the height

Find the volume of prism

Volume = Base Area × Height

since height = 10 feet

5,119.5 ft³ / 10 ft

= 511.95 ft²

formula for the area of a regular polygon is:

Area = (Perimeter × Apothem) / 2

ide length of the pentagon as 's' and the apothem as 'a'

511.95 ft² = (5s × a) / 2

angle at the center of the pentagon is 360° / 5 = 72°

72 / 2 = 36  degrees

tan(36°) = (s/2) / 17.25

solve for the value of s

s = 2 × 17.25 × tan(36°)

= 12.36 ft

5 s =

5 x 12.36 ft

=  61.8 ft

Step-by-step explanation:

For the given rectangular equation give its equivalent polar equation

Answers

Answer:

The last option

[tex]r = \dfrac{14}{6\cos\theta - \sin\theta}[/tex]

Step-by-step explanation:

Given equation is 6x - y = 14

To convert an equation in rectangular(cartesian) form, f(x, y) to polar f(r, θ) we use the following information

x = rcosθ

y = rsinθ

Substituting for x and y in the original rectangular equation 6x - y = 14,

6(rcosθ) - rsinθ = 14

Factoring out r on the left side,
r(6cosθ - sinθ) = 14

which gives

[tex]r = \dfrac{14}{6\cos\theta - \sin\theta}[/tex]

That would be choice  4

The insurance premium of a new bus is GH¢93.30 plus 15% of the insured value. What is the insurance premium of a bus whose insured value is GH¢250.00?

Answers

The requried insurance premium of a bus whose insured value is GH¢250.00 is GH¢130.80.

The insurance premium of a bus is GH¢93.30 plus 15% of the insured value.

Let's first calculate 15% of¢250.00:

15% of GH¢250.00 = 0.15 x 250.00 = GH¢37.50

Now, we can add this amount to the base premium of GH¢93.30 to find the total insurance premium for the bus:

GH¢93.30 + GH¢37.50 = GH¢130.80

Therefore, the insurance premium of a bus whose insured value is GH¢250.00 is GH¢130.80.

10. Bond A is zero-coupon bond paying $100 one year from now. Bond B is a zero-coupon bond paying
$100 two years from now. Bond C is a 10% coupon bond that pays $10 one year from now and $10 plus the $100 principal two years from now. The yield to maturity on bond A is 10%, and the price of bond B is $84.18. Assuming annual
compounding, what is the yield to maturity on Bond B?
*Make sure to input all percentage answers as numeric values without symbols,
0.0600.

Answers

The yield to maturity on Bond B is 9%

How to calculate the yield to maturity

We know that Zero Coupon Bond Value= F/(1+r)^t

F= Face Value =100

r= Rate of interest

t= time to maturity =2Yrs

Price= F/(1+r)^t

84.18 = 100/(1+r)^t

(1+r)^t=100/84.18

(1+r)^2=1.18793

1+r=(1.18793)^(1/2)

r = 1.089922 - 1

r = 8.9922%

r = 9% (Approx)

In conclusion, the yield to maturity on Bond B is 9%

What happens to a consistent slope when the y value starts to decrease and the x value remains the same over time?
A. Y decreases and X decreases

B. Y decreases and X increases

C. Y increases and X increases

D. Y increases and X decreases

Answers

The correct answer is option B:

⇒ Y decreases and X increases.

Given that;

the y value starts to decrease and the x value remains the same over time.

Now, We know that;

the slope remains constant, but the y value decreases as you move along the slope in the negative y direction, while the x value increases.

Hence,

If the y value starts to decrease while the x value remains the same over time on a consistent slope,

Thus, The correct answer is option B:

⇒ Y decreases and X increases.
