Which of the points shown below are on the line given by the equation y = 2x?
Check all that apply

Answer:

Step-by-step explanation:

From the given information:

6 cars pass on the road per minute. This implies that per minute, we will have:

6/60 passes = 0.1 car passing the road per second

Thus, for 5 sec; we have:

5 × 0.1 = 0.5

Let assume X signifies to be a random variable which denote the no of cars in the next  5 minutes and which follows a Poisson distribution.

i.e.

[tex]X \sim Poisson (0.5)[/tex]

[tex]\text{P(collision occurs) = 1 - P(no car coming in the following 5 seconds)} \\ \\ =1 - P(X=0)[/tex]

[tex]= 1- \dfrac{[e^{-0.5\times 0.5^0}]}{0!}[/tex]

[tex]= 1 - e^{-0.5}[/tex]

[tex]= 1 - 0.6065[/tex]

[tex]= 0.3935[/tex]

However, the possibility of collision supposes the deer requires 2 seconds to cross the road can be computed as follows:

Suppose Y denote the arbitrary variable that addresses the no. of cars passing the road in 2 secs, then;

[tex]Y \sim Poisson (0.2)[/tex]

[tex]\text{P(collision occurs) = 1 - P(no car coming in the following 2 seconds)} \\ \\ =1 - P(Y=0)[/tex]

[tex]= 1- \dfrac{[e^{-0.2\times 0.2^0}]}{0!}[/tex]

[tex]= 1 - e^{-0.2}[/tex]

[tex]= 1 - 0.8187[/tex]

[tex]= 0.1813[/tex]

Answer:

x=4, x=-4

Step-by-step explanation:

x^2-16=0

Add 16 to both sides;

x^2-16+16=0+16

Simplify;

x^2=16

x=[tex]\sqrt{16}[/tex], x[tex]-\sqrt{16}[/tex]

[tex]\sqrt{16}[/tex]

=4

factor the number;16

[tex]\sqrt{4^2}[/tex]

=[tex]\sqrt{4}[/tex]

-[tex]\sqrt{16}[/tex]

Factor the number 16;

[tex]\sqrt{4^2}[/tex]

=-4

Answer:

[tex]A=376.99\ cm^2[/tex]

Step-by-step explanation:

We need to find the lateral surface area of the cylinder of radius 6 cm and height of 10 cm.

We need to find the lateral surface area of the cylinder. The formula for the lateral surface area of a cylinder is given by :

[tex]A=2\pi rh\\\\A=2\pi \times 6\times 10\\A=376.99\ cm^2[/tex]

So, the lateral surface area of the cylinder is [tex]376.99\ cm^2[/tex].

Answer:

D. Point G is the center of a circle that can be inscribe in ΔABC

Step-by-step explanation:

To inscribe implies constructing a required shape or figure within a given shape, thus touching the boundaries or sides of the given shape internally.

In the given figure if point G is used as the center of a circle, it would not form an inscribed circle in the given triangle. So that the appropriate answer is Point G is the center of a circle that can be inscribe in ΔABC. Thus, option D is not true.

Answer:

The dimensions of the box so that total costs are minimum are a side length of 2 feet and a height of 5 feet.

Step-by-step explanation:

Geometrically speaking, the volume of the rectangular box ([tex]V[/tex]), in cubic feet, is represented by this formula:

[tex]V = l^{2}\cdot h[/tex] (1)

Where:

[tex]l[/tex] - Side length of the box, in feet.

[tex]h[/tex] - Height of the box, in feet.

In addition, the total cost of the box ([tex]C[/tex]), in monetary units, is defined by this formula:

[tex]C = (c_{b}+c_{t})\cdot l^{2} + 4\cdot c_{s}\cdot l\cdot h[/tex] (2)

Where:

[tex]c_{b}[/tex] - Unit cost of the base of the box, in monetary units per square foot.

[tex]c_{t}[/tex] - Unit cost of the top of the box, in monetary units per square foot.

[tex]c_{s}[/tex] - Unit cost of the side of the box, in monetary units per square foot.

By (1), we clear [tex]h[/tex] into the expression:

[tex]h = \frac{V}{l^{2}}[/tex]

And we expand (2) and simplify the resulting expression:

[tex]C = (c_{b}+c_{t})\cdot l^{2}+4\cdot c_{s}\cdot \left(\frac{V}{l} \right)[/tex] (3)

If we know that [tex]c_{b} = 0.34\,\frac{m.u.}{ft^{2}}[/tex], [tex]c_{s} = 0.05\,\frac{m.u.}{ft^{2}}[/tex], [tex]c_{t} = 0.16\,\frac{m.u.}{ft^{2}}[/tex] and [tex]V = 40\,ft^{3}[/tex], then we have the resulting expression and find the critical values associated with the side length of the base:

[tex]C = 0.5\cdot l^{2} + \frac{8}{l}[/tex]

The first and second derivatives of this expression are, respectively:

[tex]C' = l -\frac{8}{l^{2}}[/tex] (4)

[tex]C'' = 1 + \frac{16}{l^{3}}[/tex] (5)

After equalizing (4) to zero, we solve for [tex]l[/tex]: (First Derivative Test)

[tex]l-\frac{8}{l^{2}} = 0[/tex]

[tex]l^{3}-8 = 0[/tex]

[tex]l = 2\,ft[/tex]

Then, we evaluate (5) at the value calculated above: (Second Derivative Test)

[tex]C'' = 3[/tex]

Which means that critical value is associated with minimum possible total costs. By (1) we have the height of the box:

[tex]h = 5\,ft[/tex]

The dimensions of the box so that total costs are minimum are a side length of 2 feet and a height of 5 feet.

The scientific notation for this is :-6x10⁷

Answer: B 7/14

Step-by-step explanation:

Answer:

Simplified: 9 2/3

Step-by-step explanation:

Convert the mixed numbers into improper fractions

To do this, multiply the denominator by the whole number and add the numerator: (denominator × whole number + numerator)/denoninator

First fraction:

5 11/12

(12 × 5 + 11)/12

(60 + 11)/12

71/12

Next fraction:

3 9/12

(12 × 3 + 9)/12

(36 + 9)/12

45/12

Substitute these fractions in the original problem now:

71/12 + 45/12

Add the numerators only. The denominators stay the same.

(71 + 45)/12

116/12

Now that the calculations are done, convert this back into a whole number

How many times does 12 fit into 116 equally? If you answered 9 times, then you are correct. This 9 will sit as the whole number in the fraction

12 × 9 = 108

This doesn't equal 116 perfectly so we must find the left over

116 - 108 = 8 left over (which is used as the numerator)

9 8/12

If your class or problem asks that you simplify your answer, then look at both the numerator and denominator to determine any common factors within them

8 and 12 both have common factors of 2 and 4

Since 4 is the bigger number, divide both 8 and 12 by 4 to simplify your answer

Answer:

The 95% confidence interval for the true difference in the proportion of tomato plants like these that would experience damage after receiving the kelp treatment and no kelp treatment is -0.2690 < [tex]\hat{p}_1-\hat{p}_2[/tex] < 0.02901

Step-by-step explanation:

The given data are;

The number of the group 1 plants that exhibited damage = 12

The number of plants in group 1, n₁ = 50

The number of the group 2 plants that exhibited damage = 18

The number of plants in group 2, n₂ = 50

The proportion of group 1 plants that exhibited damage, [tex]\hat p_1[/tex] = 12/50 = 0.24

The proportion of group 2 plants that exhibited damage, [tex]\hat p_2[/tex] = 18/50 = 0.36

The z-value at 95% = 1.64

The confidence interval is given by the following formula;

[tex]C.I. = \hat{p}_1-\hat{p}_2\pm z^{*}\sqrt{\dfrac{\hat{p}_1\left (1-\hat{p}_1 \right )}{n_{1}}+\dfrac{\hat{p}_2\left (1-\hat{p}_2 \right )}{n_{2}}}[/tex]

Plugging in the values, we get;

[tex]C.I. = 0.24-0.36\pm 1.64 \times \sqrt{\dfrac{0.24\left (1-0.24 \right )}{50}+\dfrac{0.36\left (1-0.36 \right )}{50}}[/tex]

Therefore, C.I. = -0.2690 < [tex]\hat{p}_1-\hat{p}_2[/tex] < 0.02901

Step-by-step explanation:

We can define a "form factor" for a triangle as ...

  f = a² +b² -c²

where c is the longest side length. It will be interpreted as follows:

For this triangle, our "form factor" is ...

  f = 15² +16² -21² = 225 +256 -441 = 40 . . . . a positive number

The triangle is Acute.

Answer:

c=[tex]\frac{d}{a}[/tex]+b

Step-by-step explanation:

a(c-b)=d

c-b=[tex]\frac{d}{a}[/tex]

c=[tex]\frac{d}{a}[/tex]+b

Replace b with 5:

6(2(5)-4)

Simplify:

6(10-4)

Subtract:

6(6)

Multiply to get the answer: 36

The answer is 36

Hey there!

6(2b - 4)

= 6(2(5) - 4)

= 6(10) - 4)

= 6(10) + 6(4)

= 60 - 24

= 36

Therefore, your answer should be: 36
