Answer:

the stock is worth $110.21

Step-by-step explanation:

The first thing you want to do is multiply 0.07 and 103, to find out what 7% of 103 is. When you multiply those two numbers you are going to get 7.21. You are then going to add 103 and 7.21 to find out how much it would be worth now.

Answer:

$110.21

Step-by-step explanation:

well 7% of 103 is 7.21  so if you add that to 103 it = 110.21

The statement which BEST describes why Trevor’s conclusion was incorrect is B. The data shows no relationship between class size and the number of absences.

Scatterplots are the plotting of set of points on a vertical axis and an horizontal axis. The shows the correlation extent between the numbers of the observed quantities.

Given a scatterplot which shows the number of absences in a week for classes of different sizes.

From the scatterplot, we can see that,

For a class size of 15, there are 2 kind of absences, 2 and 10.

For class size of 20, there is a positive correlation.

Then again it increases and decreases for various sizes.

So there is no relationship in particular with the 2 variables.

Hence the correct option is B.

3024

Step-by-step explanation:

3024

Option (D) 3024 is the permutation value is the correct answer.

A permutation is an arrangement of objects in a definite order. It is a number of ways a particular set can be arranged, where the order of the arrangement matters.

For the given situation,

The value of 9P4

The formula to find permutation is

[tex]nP_{r}=\frac{n!}{(n-r)!}[/tex]

Here, n = 9 and r = 4

⇒ [tex]9P_{4}=\frac{9!}{(9-4)!}[/tex]

⇒ [tex]\frac{9!}{5!}[/tex]

⇒ [tex]\frac{5!(6)(7)(8)(9)}{5!}[/tex]

⇒ [tex](6)(7)(8)(9)[/tex]

⇒ [tex]3024[/tex]

Hence we can conclude that option (D) 3024 is the permutation value is the correct answer.

Danny's speed is given:

Andrew's speed is found from the table.

Since its the direct relationship, we find it using one pair of values:

Danny is faster as 15 mph > 14.5 mph

Speed =Distance/Time

Here speed is equal to slope of box

Danny is faster as his one is 15mph

Answer:

C

Step-by-step explanation:

In order to find "b" (the y-intercept) from the equation y=mx+b ... If you know the slope (m), use any one of the given points by substituting the Y value of the given point for y, and substituting the X value of the given point for x. Solve for b = Y-mX.

Answer:

To the nearest cent, the accumulated amount over the 10 years is $5,752.67

Step-by-step explanation:

Here, we want to use the given formula to find the accumulated amount on the deposit/investment

we have this as follows;

A = P(1 + r/k)^kt

P is the amount invested which is the principal = $3,500

r is the interest rate = 5% = 5/100 = 0.05

k is the number of times interest is compounded yearly = 4

t is the number of years = 10

Substituting these values in the formula, we have;

A = 3500(1 + 0.05/4)^(4 * 10)

A = 3500 (1 + 0.0125)^40

A = 3500(1.0125)^40

A = $5,752.67

Answer:

16x-2

Step-by-step explanation

Area of the garden = length × width

Substitute the given value

15x 2 - 7x - 2. = 5x+1 × width

Factorize the area

15x^2 - 7x - 2.

15x²-10x+3x -2 =0

5x(3x-2)+1(3x-2)

5x+1(3x-2)

Hence other side so be 3x-2

Perimeter = 2(L+W)

P = 2(5x+1+3x-2)

P = 2(8x-1)

P = 16x-2

Hence the expression that represents the Perimeter is 16x-2

Answer:

[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]

Step-by-step explanation:

Since the hyperbola opens left and right with a center at the origin, then

[tex]\frac{x^{2} }{^{2} } - \frac{y^{2} }{b^{2} } = 1[/tex]

In the graph a = 60 and b = 11

So

[tex]\frac{x^{2} }{60^{2} } - \frac{y^{2} }{11^{2} } = 1[/tex].

[tex]\frac{x^{2} }{3600} - \frac{y^{2} }{121} = 1[/tex]

Answer:

The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].

Step-by-step explanation:

Area of a sector = (θ ÷ 360) [tex]\pi[/tex][tex]r^{2}[/tex]

where θ is the central angle of the sector, and r is the radius of the circle.

From the diagram give, diameter of the circle is 26 m. So that;

r = [tex]\frac{diameter}{2}[/tex]

 = [tex]\frac{26}{2}[/tex] = 13 m

θ = 360 - (180 + 160)

  = 360 - 340

  = [tex]20^{o}[/tex]

Thus,

area of the given sector = [tex]\frac{20}{360}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]

                                        = [tex]\frac{20}{360}[/tex] x x [tex]\frac{22}{7}[/tex] x 169

                                         = 29.5079

The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].

Answer:

y = 2x+1

Step-by-step explanation:

From the question,

Using the equation of a straight line

y = mx+c................. Equation 1

Where m = slope of the line, c = intercept on the y axis.

From the graph, The two point co-ordinate shown os

Point 1 = (-2,0)

Point 2 =(6,4)

s = (y₂-y₁)/(x₂-x₁).............. Equation 2

Where y₂ = 6, y₁ = -2, x₂ = 4, x₁ = 0

Substitute into equation 2

s = (6-(-2))/(4-0)

s = (6+2)/4

s = 8/4

s = 2.

Also from the graph,

c = 1

Substitute these values into equation 1

y = 2x+1

Hence the equation of the line is y = 2x+1

The table is linear because it goes up at a consistent rate each time.

Remark

I hope you have some idea how to make your calculator use logs. This problem is impossible without being able to take the log of each side.

Solution

log(8)^x > log 24        Logs lets you bring down x and multiply it by log24

x log 8 > log 24         Be careful what you do next. Don't use log 3

x > log(24)/log(8)

x > 1.3802/0.9031

x>1.5284

As wrong as this may look, it is correct.

Check it

8^1.5284 = 24.00395

The difference is that 1.5284 has been rounded just a slight bit.

Answer: No slope.

Step-by-step explanation:

No slope, the x values are the same yet they have different Y values so there isn't a slope and this isn't a function.

Answer:

d, the number of degrees that the temperature was lowered by

Step-by-step explanation:

The dependent variable in this scenario would be d, the number of degrees that the temperature was lowered by. This is because the value of this variable depends on the actual amount of hours that have passed by. Therefore, depending on the number of hours, the value of d could be completely different. The variable h for the number of hours does not depend on any other variable in the equation and has its own value, but since d depends on h then it would be the dependent variable in this scenario.

Answer:

• Median for Amo

• Mean for Max

Step-by-step explanation:

Amo's mean score:

= (97 + 92 + 89 + 55 + 90)/ 5

= 84.60

= 85

Max's mean score:

= (68 + 97 + 65 + 92 + 65) / 5

= 77

Amo's median:

First arrange the numbers in ascending order:

55, 89, 90, 92, 97

Median is middle which is 90.

Max's median:

65, 65, 68, 92, 97

Median is 68

Mr Javier should use Median for Amo and Mean for Max.
