The population after 50 years will be 26,765,774.

Percentage is a measurement to find value of given number out of hundred.

Given that,

The current population of Canada=35,687,699.

As per given condition the population is decreasing 0.5% per year,

So after 50 year the population will decrease =50×0.5%=25%

After 50 year the 25% population will decrease, and 75% will remain.

The remaining population = 35,687,699×75/100=26,765,774.

Nicoletta can withdraw $55 from her savings account for 24 weeks until the balance reaches $0 .

Nicoletta sells jewelry during summer vacation .

From the table we can gather the following information:

Expenses = $ 26

Revenue = $132

Profit = $(132-26) = $ 106

Now she sells for 10 weeks.

profit each week  = $ 106

Total profit over 10 weeks = $ 106 × 10 = $ 1060

Money deposited in the account after 10 weeks = $ 1060

Money originally in the account = $260

Total amount of money in savings account

= $ 1060 + $260

= $ 1320

She withdraws 55 each week.

Number of weeks it will sustain at that rate = 1320 / 55 =24

Hence the savings account will have 0 after 24 weeks.

The radius of the roundabout whose circumference is given is: 55 feet.

What is circumference?

The perimeter of a circle or ellipse is known as its circumference in geometry (from the Latin circumferens, meaning "carrying around"). That is, if the circle were opened up and straightened out to a line segment, the circumference would be the length of the arc.

As given in the question ,  

The circumference of the roundabout is 345.4 feet.

and we need to find the radius,

We know that, the circumference is calculated by:

Circumference = 2 π r

So, putting value of circumference,

345.4 = 2 (3.14) r

r = 345.4/6.28

r = 55 feet

For the function F(x, y) = x³ + y³ - 3x² - 6y² - 9x ,  the local maximum value is 5 and the local minimum value is -3. The graph is discontinuous, so we cannot locate the saddle points.

In mathematics, a saddle point or minimax point is a point on the surface of the graph of a function where the slopes (derivatives) in orthogonal directions are all zero (a critical point), but which is not a local extremum of the function.

We have the following function -

F(x, y) = x³ + y³ - 3x² - 6y² - 9x

We will plot the 3 dimensional graph of this function. From the model it can be seen that, the local maximum value is 5 and the local minimum value is -3. Since the graph is discontinuous, we cannot locate the saddle points.

Therefore, for the function F(x, y) = x³ + y³ - 3x² - 6y² - 9x ,  the local maximum value is 5 and the local minimum value is -3. The graph is discontinuous, so we cannot locate the saddle points.

Lines 5(x+3) and y=5x+1 both are parallel.

What are parallel lines?

Parallel lines in geometry are coplanar, straight lines that don't cross at any point. In the same three-dimensional space, parallel planes are any planes that never cross. Curves with a predetermined minimum distance between them and no contact or intersection are said to be parallel.

Here, we have

Given equations = 5(x+3) and y=5x+1

Now we write both equations in standard form and we get

y = 5x + 3,

y = 5x + 1

Then, we compare the slopes of both equations and we get

Slope = 5

Jim needs a score of 115 on his third test to keep an average of 89 or greater.

A mean represents the average value among a set of values.

Mean = (sum of all values)/(total number of values)

In other words, mean is the value assigned to each member of set after fair distribution. It means that if a set of n values has a mean of x, we can assume the set to be 'x' value recurring n times over the sample.

In this case, we have 3 test results: 83, 69 & x, where x is the unknown result of 3rd test. Our required minimum average/mean is 89.

Substituting these in our formula for mean, we get:

[tex]89=\frac{83+69+x}{3} \\89*3=152+x\\x=267-152=115[/tex]

For part A, first of all, you need to multiply both sides by 2.

4x - 1 = 2x + 14

Then, you need to add 2 to both sides.

4x = 2x + 15

Now, you need to subtract 2x from both sides.

2x = 15

Finally, you need to divide both sides by 2.

x = 7.5

So the answer to part A is 7.5

Now for part B.

First of all, you need to multiply both sides by 3.

9x + 6 = 2x + 13

Next, you need to subtract 6 from both sides.

9x = 2x + 7

Now, you need to subtract 2x from both sides.

7x = 7

Finally, you need to divide both sides by 7.

x = 1

Because a 270° rotation around the origin and a subsequent reflection over the x-axis translate ABC onto LMN, the figures are congruent.

Two figures are said to be "congruent" if they can be positioned perfectly over one another. Both of the bread slices are the same size and shape when stacked one on top of the other. Congruent refers to things that are exactly the same size and form. Congruent refers to something that is "absolutely equal" in terms of size and form. The shapes hold true regardless of how we rotate, flip, or turn them. Draw two circles with the same radius, for instance, cut them out, then stack them on top of one another. In geometry, two figures or objects are said to be congruent if their shapes and sizes match, or if one is the mirror image of the other.

AS per the concept of trigonometric ratios for theta, the value of cos θ = 2√6/5 , tan θ = -1/2√6 , cosec θ = -5, sec θ = 5/2√6 and the value of cot θ = -2√6.

Trigonometric ratio:

In math, there are six trigonometric ratios they are sine (sin), cosine (cos), tangent (tan), cotangent (cot), cosecant (cosec), and secant (sec).

Given,

The angle theta is in standard position with a terminal arm in quadrant IV. If sin θ =-1/5.

Now, we have to find the remaining five trigonometric ratio of the θ.

As we know that,

sin²θ + cos²θ =  1

Here we know that value of sin θ = -1/5, then the value of cos θ is calculated as,

=> (-1/5)² + cos² θ = 1

=> 1/25 + cos² θ = 1

=> cos² θ = 1 - 1/25

=> cosθ = √24/25

=> cos θ = 2√6/5

So, the value of tan θ = -1/2√6

Then the value of cosec θ = -5, sec θ = 5/2√6 and the value of cot θ = -2√6.

The t-score of 2.779 is used to find the 99% confidence interval for the population mean.

Given,

Assume that orangutans' heights, measured in inches, are regularly distributed with an unidentified mean and standard deviation. The population means are calculated using the orangutan heights of 27 orangutans that were randomly selected.

What t-score should be applied to determine the population mean's 99% confidence interval?

n = 27

confidence level = 0.99

We have to find a critical value for the confidence level of 0.99.

To find the critical value we need degrees of freedom and significance level.

df = n-1 = 27 - 1 = 26

α = 1 - 0.99 = 0.01

α/2 = 0.01/2 = 0.005

The probability that if we select 4 fish from the tank, at least 2 will be white is 0.7863.

Given,

A fish tank in a pet store has 21 fish in it. 9 are orange and 12 are white. determine the probability that if we select 4 fish from the tank, at least 2 will be white;

The probability that the fish is white = 12/21

                                                      = 4/7

To find the probability that at least two will be white,

P(x ≥ 2) = 1 - P(x < 2) = 1 - ( P(0) + P(1) )

The binomial distribution formula [tex]P(x) = (^n_x)p^xq^n^-^x[/tex] where p is the probability of success and q is the probability of failure.

From the above formula;

P(x ≥ 2) = 1 + [ (3/7)⁴ + 4*(4/7)*(3/7)³ ]

            = 0.7863

Hence, the likelihood that if we select 4 fish from the tank, at least 2 will be white is 0.7863.
