can someone please help me with this question I'm not really good with graphs​

Answer:

x=12 is the answer to this question

The red light lasts between 2.5 minutes and 3.5 minutes is 95 %. Then the correct option is C.

It is also called the Gaussian Distribution. It is the most important continuous probability distribution. The curve looks like a bell, so it is also called a bell curve.

At an intersection, the red-light times are normally distributed with a mean time of 3 minutes and a standard deviation of 0. 25 minutes.

In this case, the mean is 3 and the standard deviation is 0.25, We move one space to the right that would represent 3.25 minutes, one more space to the right that is 3.50 minutes. Similarly, we move one space to the left, this would be 2.75, one more space to the left, and the shows 2.50 minutes.

Thus, the correct option is C.

More about the normal distribution link is given below.

Answer:  Yes, Daniel has enough money to buy 2 pens.

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

Explanation:

x = cost of one pencil

y = cost of one pen

4x = cost of 4 pencils

3y = cost of 3 pens

4x+3y = cost of 4 pencils and 3 pens

100 - (4x+3y) = amount Daniel has left = 7 dollars

100-(4x+3y) = 7 is one equation we can form

Another equation we can form is x = y+3 because "each pencil costs $3 more than each pen".

Let's plug that into the first equation and solve for y.

100-(4x+3y) = 7

100-(4(y+3)+3y) = 7

100 - (4y+12+3y) = 7

100 - (7y+12) = 7

100 - 7y - 12 = 7

-7y + 88 = 7

-7y = 7-88

-7y = -81

y = -81/(-7)

y = 11.57 is the cost of one pen

2y = 2*11.57 = 23.14 is the cost of two pens.

Since this is less than $25, this means he has enough to buy two pens. This assumes that we either ignore tax, or the tax is already included in the listed prices.

Answer:

No

Step-by-step explanation:

To Find if -17/-40 equal to -0.425...

We First have to turn -17/-40 into a decimal;

-17/-40 = 0.425 { Negative + Negative = Positive }

Thus,

0.425 > -0.425

Hence, Answer is -17/-40 is Not equal to -0.425

Step-by-step explanation:

Solution In given triangle, 2B=12x+3

12x+3

∠A = 86 , ∠C = 43°

We know that, Sum of all angles of triangle is 180°

86

∴ ∠A+ ∠B + ∠C = 180°

a

86 + 12x+3+ 43 = 180°

The missing side of the fence measures 15 ft

The perimeter of the fence is 40 ft

The area inside the fenced in section is 60 ft²

The fence is triangular and a right triangle.

A right triangle has one of its angle as 90 degrees. Therefore, the sides can be found using Pythagoras theorem.

c² = a² + b²

17² - 8² = b²

b = 15 ft

AC = 15 ft

perimeter of the triangle = 15 + 8 + 17 = 40 ft

Area of the triangle = 1 / 2 × 15 × 8 = 60 ft²

Therefore,

The missing side of the fence measures 15 ft

The perimeter of the fence is 40 ft

The area inside the fenced in section is 60 ft²

Step-by-step explanation:

The amount of money that you will have at the end of the year from your brand-new savings account is $600.69.

The future value is the value of periodic cash flows in the future.  It can be computed using an online finance calculator as follows:

N (# of periods) = 24 (12 X 2)

I/Y (Interest per year) = 0.12% (0.01% X 12)

PV (Present Value) = $0

PMT (Periodic Payment) = $25

Results:

FV = $600.69

Sum of all periodic payments = $600.00 ($25 X 24)

Total Interest = $0.69

Thus, the amount of money that you will have at the end of the year from your brand-new savings account is $600.69.

Answer:

1/15 is simplest, answer 2/30

Step-by-step explanation:

11/30 - 3/10. Find LCD

Since it's 30, leave 11/30 how it is and turn 3/10 into 9/30

Next, 11-9=2

meaning 2/30, which if you divide by 2 both sides, you get 1/15.

Answer:

3 or 2.999 (probably 3)

Step-by-step explanation:

So the volume of a cylinder =  πr^2 * h

h = height

r = radius

now we know the radius. Leaving us with a simple equation which is:

π*9*h = 9π*h = 84.78 =

π*h = 9.42

h = 9.42 / π = 2.99847912785......

but we can round this to 2.999 or just 3. if you use 2.999 the volume is 84.79 which is as close as I'm gonna try to get. And you might ask why we're rounding to 2.999 and not 2.998? This is because that huge number is the minimum. And 2.998 is smaller than that huge number, meaning it would technically be less than 84.78 cubic ft. But this doesn't really matter because the answer your teacher is probably looking for is 3.

√ 80/16=t t=0.5590169943749474

Step-by-step explanation:

The function h(t) = -16t^2 + 70 is a quadratic function, and the stick hits the ground at about 2.092 seconds

Here, we have,

to determine the time it hits the ground:

The function is given as:

h(t) = -16t^2 + 70

Next, we plot the graph of the function h(t)

From the graph of the function h(t) (see attachment), we have the following highlight:

t = -2.092 and t = 2.092 when h(t) = 0

Time cannot be negative.

So, we have:

t = 2.092

This means that the stick hits the ground at about 2.165 seconds

Step-by-step explanation:

Recursive Rule would get by just carefully analysing the pattern and common difference.

a1 = 0 ,

d = a2-a1 ==> d = -3-0 ==> d = -3 ...(common difference)

so here, an would be,

an = a1 + (n-1) d

==> an = 0 + (n-1)(- 3)

==> an = -3(n-1)

==> an = -3n+3

so the final answer is [an = -3n + 3 ]
